JP 2001-271918 A

  Although the number of connectors can be reduced if the control unit is connected to the solenoid valve connector and sensors with a single-core wiring as in the above drive unit, the connection between the electronic component and other components can be reduced. Since much work and time are required for the work, the assemblability is deteriorated and the manufacturing cost may be increased.

  SUMMARY OF THE INVENTION Accordingly, it is a primary object of the present invention to provide a transmission hydraulic control device having good assemblability.

  The transmission hydraulic control apparatus of the present invention employs the following means in order to achieve the above-mentioned main object.

The transmission hydraulic control device according to the present invention includes:
A hydraulic control device for a transmission which is attached to an automatic transmission and used for shift control of the automatic transmission,
A valve body having a plurality of oil passages;
A plurality of solenoid valves each having a first connector and forming a hydraulic circuit together with the oil passage in parallel with the valve body so that the connection directions of the first connectors are parallel to each other;
An electronic control unit for driving and controlling the plurality of solenoid valves;
A flexible wiring board electrically connected to the electronic control unit;
A plurality of second connectors each capable of being coupled to the first connector and electrically connected to the flexible wiring board;
A main body that supports the electronic control unit and is attached to the valve body from the side of the plurality of solenoid valves, and the first connector corresponding to the main body when the main body is attached to the valve body. A support member including a plurality of second connectors and a movable holding unit supported by the main body so as to be movable in the connection direction;
Is provided.

  When assembling the transmission hydraulic control device, a plurality of solenoid valves each having a first connector are arranged in parallel on the valve body so that the connecting directions of the first connectors are parallel to each other. Next, the main body of the support member that supports the control unit is attached to the valve body from the side of the plurality of solenoid valves. When the support member is thus attached to the valve body, the second connectors held by the movable holding portion of the support member face the corresponding first connectors of the solenoid valves. And if the movable holding part of a support member is moved to the connection direction of a 1st connector with respect to a main body in this state, several sets of 1st and 2nd connectors can be couple | bonded together very easily. . Further, since each second connector and the control unit are connected by a flexible wiring board having flexibility, the distance between each second connector and the control unit is changed by moving the movable holding portion with respect to the main body. Even so, each second connector, that is, each solenoid valve, and the control unit can be electrically connected satisfactorily, and there is no need to perform complicated wiring. Therefore, this transmission hydraulic control device has an extremely good assembly property.

  The connection direction of the first connector may be substantially orthogonal to the mounting direction of the support member with respect to the valve body. Thereby, compared with the case where the connection direction of the first connector and the mounting direction of the support member with respect to the valve body are coincident (in parallel), the first and second connectors coupled to each other in the mounting direction. Since the dimensions can be reduced, the transmission hydraulic control device can be made compact in the mounting direction (height direction).

  In this case, the plurality of solenoid valves may be arranged in parallel to the valve body such that the respective axial directions are substantially orthogonal to the mounting direction of the support member with respect to the valve body, and the first connector is connected to the connection body. The solenoid valve may be attached so that the direction is parallel to the axial direction of the solenoid valve. Thus, even if a relatively long solenoid valve is used, the transmission hydraulic control device can be made compact in the mounting direction (height direction).

  Further, each of the solenoid valves guides the second connector held by the movable holding portion so as to face the first connector when the main body of the support member is attached to the valve body. A guide part may be provided. As a result, when the main body of the support member is attached to the valve body, each of the second connectors can be satisfactorily opposed to the corresponding first connector, so that the assembly of the transmission hydraulic control device is further improved. This can be further improved.

  In this case, the guide portion has a pair of inclined surfaces that are provided on the solenoid valve so as to be adjacent to the first connector in the connection direction, and that are opposed to each other so that the interval increases as the distance from the solenoid valve increases. The second connector may be accommodated so as to face the first connector. If such a guide part is employ | adopted, it will become possible to oppose each 2nd connector favorably with the corresponding 1st connector, while making a main body approach a valve body at the time of attachment of a supporting member.

  A slope may be formed on the side of the second connector so as to follow the slope of the guide portion. As a result, each of the second connectors can be more accurately opposed to the corresponding first connector.

  Furthermore, the solenoid valve may be provided with a connection direction guide portion that engages with the second connector and guides the second connector in the connection direction. Thereby, when the movable holding part of the support member is moved with respect to the main body, the first connector and the second connector can be smoothly coupled.

  The shift ECU 41 and the SBWECU 42 are circuit boards on which various electronic components are mounted. The flexible wiring board 43 is a flexible deformable wiring material having a thickness of, for example, about 0.1 to 0.2 mm, and is an adhesive to a base film or a base film formed of a resin such as a polyimide resin. It includes a conductor for wiring made of copper foil or the like attached via a layer, a cover film for covering the conductor for wiring, and the like (all not shown). The flexible wiring board 43 is bonded to the circuit board of the shifting ECU 41 or SBWECU 42, and the plurality of bonding terminals formed on the flexible wiring board 43 are electrically connected to the bonding terminals of the shifting ECU 41 or SBWECU 42 via bonding wires or the like. Connected. The unit base 44 is made of a low expansion metal having excellent thermal conductivity and a relatively small thermal expansion coefficient, and is bonded to the flexible wiring board 43 from the opposite side of the speed change ECU 41 and the like. The unit base 44 functions not only as a support for the speed change ECU 41 and the SBWECU 42 but also as a heat sink for dissipating heat.

  As shown in FIGS. 1, 2, and 5, the support member 60 includes a main body 61 that supports the control module 40 and the switch base 50 and is attached to the valve body 21, and a plurality of members extending outward from the main body 61. And a movable holding portion 63 that holds a plurality of connectors 64 that are slidably supported by the pair of guide portions 62 and that can be coupled to the valve-side connector 34 described above.

  The main body 61 of the support member 60 is a rectangular frame formed of resin. As shown in FIGS. 1 and 2, an opening for exposing the speed change ECU 41 and the SBWECU 42 of the control module 40, and the switch base 50. And an opening for exposing the hydraulic switch 51 supported by the motor. The control module 40 is fixed to the main body 61 of the support member 60 via bolts or the like so that the shifting ECU 41 and the SBWECU 42 are positioned on the valve body 21 side. The switch base 50 includes the hydraulic switch 51 on the valve body 21 side. It fixes through a volt | bolt etc. so that it may be located in (refer FIG. 5). The main body 61 is connected via a bolt to a base formed on the valve mounting surface of the valve body 21 from the solenoid valves 30 and 31 side so that each hydraulic switch 51 and the hydraulic pressure introduction hole 24 on the valve body 21 side communicate with each other. It is attached. That is, the support member 60 (main body 61) is attached to the valve body 21 in a direction (vertical direction) substantially orthogonal to the valve mounting surface (see FIG. 2).

  As shown in FIGS. 2 and 5, two guide portions 62 of the support member 60 are extended outward from each of a pair of opposite side portions of the main body 61, and the main body 61 is connected to the valve body. When attached to the valve 21, the valve body 21 extends in the width direction. Further, one movable holding portion 63 is provided on each side of the main body 61, and is formed to be slidably engageable with a pair of guide portions 62, respectively. Thereby, when the main body 61 is attached to the valve body 21, each movable holding portion 63 can approach and separate from the main body 61 along the width direction of the valve body 21. The same number of connectors 64 as the linear solenoid valve 30 are fixed to the movable holding portion 63 located on the upper side in FIG. 5 so as to face the main body 61, and the movable holding portion 63 located on the lower side in FIG. 5. The same number of connectors 64 as the on / off solenoid valves 31 are fixed so as to face the main body 61. In the embodiment, the attachment position of each connector 64 with respect to the movable holding portion 63 is determined when each support member 60 is attached to the valve body 21 with each movable holding portion 63 being (most) separated from the main body 61. 64 is defined so as to enter the guide portion 35 of the solenoid valve 30 or 31 and to face the corresponding valve-side connector 34.

  Each connector 64 has a terminal structure that can be coupled to the above-described valve-side connector 34, and is electrically connected to the connection end 43 a of the flexible wiring board 43 of the control module 40 fixed to the main body 61. Further, as shown in FIG. 3, a slope 64 a is formed on the side portion of the connector 64 of the embodiment along the slope 35 a of the guide portion 35 of the connector block 33. In the embodiment, the inclination angle of the inclined surface 64 a of the connector 64 is substantially the same as the inclination angle of the inclined surface 35 a of the guide portion 35. The connector 64 is shaped so that the slopes 64 a on both sides abut against the slope 35 a of the guide part 35 and face the valve-side connector 34 when the bottom part abuts on the bottom part of the guide part 35. It should be noted that the inclination angle of the inclined surface 64a of the connector 64 and the inclination angle of the inclined surface 35a of the guide portion 35 do not have to coincide completely.

  Next, an assembly procedure of the hydraulic control apparatus 20 according to the embodiment will be described with reference to FIGS.

  When assembling the hydraulic control device 20 of the embodiment, the valve insertion portion corresponding to the linear solenoid valve 30 and the on / off solenoid valve 31 each having the connector block 33 (valve side connector 34) so that the electromagnetic portion is exposed to the outside. It is inserted into 22 or 23 and fixed to the valve body 21 using a pin (not shown), and a parking cylinder and other sensors are attached to the valve body 21. Thus, the plurality of linear solenoid valves 30 are arranged side by side so as to be adjacent to each other on one side of the center line extending in the longitudinal direction of the valve body 21 and extend in the width direction of the valve body 21, respectively. 31 are juxtaposed on the other side of the center line extending in the longitudinal direction of the valve body 21 so as to be adjacent to each other and extend in the width direction of the valve body 21. The valve-side connector 34 of each linear solenoid valve 30 is parallel to the width direction of the valve body 21 and opens outward, and the guide portion 35 is positioned outward of the valve-side connector 34. It will be. Similarly, the valve-side connectors 34 of the respective on-off solenoid valves 31 are parallel to the width direction of the valve body 21 and open to the outside so that the valve-side connectors 34 of the on-off solenoid valves 31 are outward. Also, the guide portion 35 is located.

  In addition, the control module 40 is fixed so that the speed change ECU 41 and the SBWECU 42 are located on the valve body 21 side with respect to the main body 61 of the support member 60, and the connection end 43 a of the flexible wiring board 43 of the control module 40 is electrically connected. The plurality of connectors 64 connected to are fixed to the corresponding movable holding portions 63. A plurality of connectors 64 may be fixed to the movable holding portion 63 in advance, and the flexible wiring board 43 and each connector 64 may be electrically connected when the control module 40 is attached to the main body 61. Further, the switch base 50 is fixed so that the hydraulic switch 51 is positioned on the valve body 21 side with respect to the main body 61 of the support member 60. Then, the main body 61 of the support member 60 that supports the control module 40 and the switch base 50 is attached to the valve body 21 from the solenoid valves 30 and 31 side in a state where each movable holding portion 63 is separated from the main body 61. Thus, when the support member 60 is attached to the valve body 21, each connector 64 held by the movable holding portion 63 of the support member 60 is guided by the pair of inclined surfaces 35a of the guide portion 35 and smoothly enters the guide portion 35 ( (See FIG. 6). As shown in FIG. 7, when the bottom portion of each connector 64 comes into contact with the bottom portion of the guide portion 35, the slopes 64a on both sides come into contact with the slope 35a of the guide portion 35. Against. Further, the protrusion 64p of each connector 64 and the connection direction guide groove 36 of the guide portion 35 are engaged with each other.

  Here, as shown in FIG. 8, when the linear solenoid valve 30 or the on / off solenoid valve 31 is inserted and fixed in the valve insertion portion 22 or 23, the valve-side connector 34 or the guide portion 35 is in contact with the valve mounting surface. In the embodiment, even if the valve-side connector 34 and the guide portion 35 are inclined, each connector 64 is properly aligned with the corresponding valve-side connector 34. Can be made. That is, when the support member 60 is moved closer to the valve body 21, one of the inclined surfaces 64a formed on the side portions on both sides of each connector 64 held by the movable holding portion 63 is guided as shown in FIG. It abuts on one inclined surface 35 a of the portion 35. As the support member 60 approaches the valve body 21, the connector 64 slides (moves) to the bottom of the guide portion 35 in a state where the one inclined surface 64a and the inclined surface 35a of the guide portion 35 are in contact with each other. Therefore, in the above embodiment, even if the valve-side connector 34 and the guide portion 35 are inclined, as shown in FIG. 10, each connector 64 can be handled only by moving the support member 60 closer to the valve body 21. It is possible to satisfactorily face the valve side connector 34.

  When the support member 60 is attached to the valve body 21 and each connector 64 held by the movable holding portion 63 of the support member 60 faces the corresponding valve-side connector 34 of the solenoid valve 30 or 31, as shown in FIG. The protrusion 64p formed on the bottom of each connector 64 and the connection direction guide groove 36 formed on the guide portion 35 are engaged with each other. In this state, as shown in FIG. 12, if the movable holding portion 63 of the support member 60 is moved in the connection direction of the valve-side connector 34 (the width direction of the valve body 21) with respect to the main body 61, a plurality of sets The valve side connector 34 and the connector 64 can be joined together very easily. At this time, each connector 64 is guided by the connection direction guide groove 36 of the guide portion 35 extending in the connection direction of the valve side connector 34 and moves to the valve side connector 34 side. Can be combined smoothly. Further, even if the distance between each connector 64 and the shifting ECU 41 etc. is changed by moving the movable holding portion 63 relative to the main body 61, the flexible wiring between each connector 64 and the shifting ECU 41 etc. is flexible. Since the connection is made by the plate 43, the change in the distance between each connector 64 and the shifting ECU 41 and the like is absorbed by the bending of the flexible wiring board 43, so that each connector 64, that is, each solenoid valve 30 and 31, and the shifting ECU 41 and the like are connected. Good electrical connection can be maintained. Further, as in the embodiment, the guide portion 35 guides the connector 64 along the mounting direction of the support member 60 with respect to the valve body 21 to oppose the valve side connector 34, and the length of the receiving portion of the valve side connector 34. By making the length relatively short, the flexure of the flexible wiring board 43 associated with the connection between the valve-side connector 34 and the connector 64 can be made as small as possible.

  When the connection between the valve side connector 34 and the connector 64, that is, the connection between the linear solenoid valve 30 or the on / off solenoid valve 31 and the control module 40 (shifting ECU 41) is completed, a bolt or the like is applied to the valve body 21. And the integrated valve body 21, control module 40, switch base 50, support member 60 and strainer 75 are fixed to the housing of the transmission case 12 of the automatic transmission 10, and the strainer 75 and the like are fixed. An oil pan 70 is attached to the lower part of the transmission case 12 so as to cover from below.

  As described above, when assembling the hydraulic control device 20 according to the embodiment, the valve body of the plurality of solenoid valves 30 and 31 each having the valve side connector 34 is set so that the connection directions of the valve side connectors 34 are parallel to each other. 21 in parallel. Next, the main body 61 of the support member 60 that supports the control module 40 (such as the shifting ECU 41) is attached to the valve body 21 from the plurality of solenoid valves 30 and 31 side. When the support member 60 is thus attached to the valve body 21, the connectors 64 held by the movable holding portion 63 of the support member 60 face the corresponding valve-side connectors 34 of the solenoid valves 30 or 31, respectively. In this state, if the movable holding portion 63 of the support member 60 is moved in the connecting direction of the valve-side connector 34 with respect to the main body 61, the plurality of sets of valve-side connectors 34 and connectors 64 are very easily bundled together. Can be combined. Further, each connector 64 and the shifting ECU 41 and the like are connected by a flexible wiring board 43 having flexibility, so that each connector 64 and the shifting ECU 41 and the like are moved by moving the movable holding portion 63 relative to the main body 61. Even if the distance between the connector 64 and the solenoid valves 30 and 31 and the shifting ECU 41 and the like can be electrically connected well, it is not necessary to carry out complicated wiring. Therefore, the hydraulic control device 20 of the embodiment has an extremely good assembly property.

  In the above embodiment, the connection direction of the valve-side connector 34 is parallel to the width direction of the valve body 21, so that the connection direction of the valve-side connector 34 is substantially orthogonal to the mounting direction of the support member 60 to the valve body 21. (See FIG. 2). Thereby, compared with the case where the connection direction of the valve side connector 34 and the mounting direction of the support member 60 with respect to the valve body 21 are coincident (in parallel), the valve side connector 34 and the connector 64 coupled to each other. Since the dimension in the mounting direction can be reduced, the hydraulic control device 20 can be made compact in the mounting direction, that is, the height direction. Further, in the above embodiment, the plurality of solenoid valves 30 and 31 have a valve body whose axial direction is parallel to the width direction of the valve body 21, that is, substantially orthogonal to the mounting direction of the support member 60 with respect to the valve body 21. The valve-side connector 34 is attached to the solenoid valves 30 and 31 so that the connection direction thereof is parallel to the axial direction of the solenoid valves 30 and 31. Thereby, even if relatively long solenoid valves 30 and 31 are used, the transmission hydraulic control device 20 can be made compact in the mounting direction (height direction).

  In each of the solenoid valves 30 and 31, the connector 64 held by the movable holding portion 63 is opposed to the valve-side connector 34 when the main body 61 of the support member 60 is attached to the valve body 21. A guide portion 35 is provided to guide the user. Thus, when the main body 61 of the support member 60 is attached to the valve body 21, each of the connectors 64 can be satisfactorily opposed to the corresponding valve-side connector 34, so that the assembly of the transmission hydraulic control device 20 can be performed. Can be further improved. That is, in the above-described embodiment, the guide portion 35 has a pair of inclined surfaces 35a facing each other so that the distance increases as the distance from the solenoid valves 30 and 31 increases, and the connector 64 can be accommodated so as to face the valve-side connector 34. Is provided in the solenoid valves 30 and 31 so as to be adjacent to the valve-side connector 34 in the connecting direction. When such a guide portion 35 is employed, the main body 61 is attached to the valve body 21 when the support member 60 is attached even if the valve-side connector 34 and the guide portion 35 are slightly inclined with respect to the valve body 21 (mounting surface). While approaching each other, each of the connectors 64 can be properly aligned with the corresponding valve-side connector 34. Moreover, if the slope 64a is formed in the side part of the connector 64 so that it may follow the slope 35a of the guide part 35 like the said Example, each of the connectors 64 can be more correctly aligned with the corresponding valve side connector 34. It becomes possible to pair. Further, if the solenoid valve 30 and 31 are engaged with the connector 64 and the connection direction guide groove 36 for guiding the connector 64 in the connection direction of the valve-side connector 34 is provided, the movable holding portion 63 of the support member 60 is moved to the main body 61. Therefore, the valve-side connector 34 and the connector 64 can be connected smoothly.

  In addition, although the hydraulic control apparatus 20 of the said Example was demonstrated as what is applied to the automatic transmission 10 mounted in a motor vehicle, it is not restricted to this. That is, the hydraulic control device 20 according to the present invention may be applied to an automatic transmission that is mounted on a device other than an automobile.
