Description

The present invention relates to a parking lock operation device configured to operate an operating state of a parking lock mechanism by operating an operation lever provided in a vehicle interior.

A device has been proposed in which the parking lock mechanism can be manually operated via an operation cable by an operation lever provided in the vehicle interior. In such a device, the vibration of the transmission case provided with the parking lock mechanism inside may be transmitted through the operation cable to generate noise in the vehicle interior.

The device disclosed in Patent Document 1 operates the parking brake mechanism in the operating state (the state of braking the output shaft of the transmission) and the released state via the operation cable, and is transmitted from the operation cable to the vehicle interior. It has a configuration to prevent the generation of noise caused by vibration. In this configuration, the outer sheath of the parking brake operation cable is held by the mounting plate, and this mounting plate is held in a floating state by being fixed to the bracket on the parking brake mechanism side via a vibration-proof member such as vibration-proof rubber. It was done. The bracket is provided with a cylindrical stopper. When the operating lever is not operated (when released), the elastic force of the anti-vibration member separates the bracket from the stopper, which suppresses the transmission of vibration from the parking brake mechanism to the vehicle interior. .. When parking to operate the parking brake mechanism, the vibration isolator is compressed and the bracket and the stopper come into contact with each other as the operating lever is operated, whereby the tensile reaction force of the inner cable is supported by the stopper, and the parking brake mechanism of the parking brake mechanism is operated. The traction force required for operation is transmitted.

In the device of Patent Document 1, the outer sheath is held in a floating state by the vibration isolator when the parking brake mechanism is not operated, so that the transmission of vibration to the vehicle interior via the outer sheath is suppressed. However, since the transmission of vibration via the inner cable is not suppressed, there is still room for improvement in suppressing the transmission of vibration. Further, in the device of Patent Document 1, since the mounting plate is mounted on the bracket on the parking brake mechanism side via the vibration isolator, the parking brake mechanism can be accommodated even when the operation lever is not operated. Due to the relatively low frequency vibration of the transmission case, the anti-vibration member is compressed to the extent that the mounting plate and the bracket come into contact with each other or the vibration of the transmission case is substantially transmitted, and the anti-vibration member controls the vibration. It may adversely affect the suppression of vibration, especially relatively high frequency vibration.

Therefore, an object of the present invention is to provide a novel means for suppressing the transmission of vibration via an operation cable.

In order to solve the above problems, the parking lock operation device according to the present invention is used.
It is a parking lock operation device configured to selectively realize a parking state in which the rotation of wheels is locked by operating the parking lock mechanism built into the transmission case mounted on the chassis.
The operation lever located in the passenger compartment and
An operation cable that can connect the parking lock mechanism and the operation lever, the lever side cable to which the operation lever arranged in the vehicle interior is connected to one end, and the lock mechanism side to which the parking lock mechanism is connected to one end. An operation cable with a cable and
A support mechanism configured to support the operation cable on the chassis, and
A connection switching mechanism having a first connector provided at the other end of the lever-side cable and a second connector provided at the other end of the lock mechanism-side cable is provided.
Before the operation lever is operated, the connection switching mechanism establishes an incompletely connected state in which the transmission of the traction force from the first connector to the second connector is suppressed, and the operation lever is operated. After that, it is configured to establish a connected state in which the traction force is transmitted from the first connector to the second connector to the extent that the parking lock mechanism can be operated by the operating lever.
The connection switching mechanism is provided in the transmission path of the traction force from the operation lever to the support mechanism.

In the present invention, before the operation lever is operated, an incompletely connected state in which the transmission of the traction force from the first connector to the second connector is suppressed is established, so that vibration via the operation cable is established. Transmission is suppressed. After the operating lever is operated, a connected state is established in which the traction force is transmitted from the first connector to the second connector to the extent that the operating state of the parking lock mechanism can be operated by the operating lever. The traction force required to operate the parking lock mechanism is transmitted. That is, it is possible to realize the operation during the manual operation in which the operation lever is operated while suppressing the transmission of vibration during the normal operation in which the operation lever is not operated. Further, in the present invention, since the connection switching mechanism is provided in the transmission path of the traction force from the operation lever to the support mechanism, the transmission of the vibration of the transmission case to the connection switching mechanism is suppressed, and therefore, in the connection switching mechanism. The influence of vibration of the transmission case on the suppression of vibration transmission can be suppressed.

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, the vehicle 1 according to the first embodiment of the present invention has a chassis 2 provided with a rear support member 2a, an engine 3 mounted on the chassis 2, and a transmission case 4. The vehicle 1 is further provided with rubber mounts 5a and 5b for damping. The engine 3 is mounted on the chassis 2 via the rubber mount 5a. The transmission case 4 is mounted on the rear support member 2a via the rubber mount 5b.

An operation lever 6 is installed in the vehicle interior of the vehicle 1. The operating lever 6 has a swivel arm 6a and a base 6b fixed to a vehicle interior member 2b which is a part of the chassis 2, and the base portion of the arm 6a is swiftly supported by the base 6b. Inside the transmission case 4, a parking lock mechanism 7 is provided in addition to a transmission (not shown). The operation lever 6 and the outer lever 7a of the parking lock mechanism 7 can be connected by a parking lock operation cable 8 (hereinafter referred to as an operation cable 8). The operation of the operation lever 6 is transmitted to the parking lock mechanism 7 by the operation cable 8. The operation lever 6 and the operation cable 8 in the present embodiment are not used for parking / stopping in normal operation, but are caused by a failure, that is, a failure of the electric actuator M (see FIG. 2) or an electronic control device. When the parking lock mechanism 7 cannot be released by the electric actuator M, it is used as an emergency parking lock release means by the driver or the restoration worker.

The operation cable 8 includes a lock mechanism side outer sheath 9a, an intermediate outer sheath 9b, a lever side outer sheath 9c (hereinafter, appropriately referred to as an outer sheath 9), a first inner cable 10a, a second inner cable 10b, and a third inner cable 10c (hereinafter, appropriately referred to as an outer sheath 9). Hereinafter, it is appropriately referred to as an inner cable 10). The outer sheath 9 has a function of surrounding and holding the inner cable 10 and receiving a reaction force of the traction force of the inner cable 10.

In FIG. 2, the parking lock mechanism 7 is configured to lock the parking when the “P” position is selected by operating a shift lever (not shown) provided in the vehicle interior. The parking lock mechanism 7 is driven by the electric actuator M. The shift position in the present embodiment includes a P position, an R position, an N position, and a D position, and among these, the R position, the N position, and the D position are referred to as non-P positions.

The parking lock mechanism 7 has a shaft 11 that is rotationally driven by the electric actuator M. The detent plate 12 is fixed to the shaft 11 and rotates together with the shaft 11. A rod 13 is connected to the lower end of the detent plate 12, and the rod 13 moves forward and backward in the longitudinal direction as the detent plate 12 rotates. In order to lock the parking gear 14 fixed to the output shaft of the transmission in the transmission case 4 and thereby lock the rotation of the wheels (not shown), the parking lock pole 15 is used as the transmission case. It is rotatably fixed to 4. In order to moderate the rotation of the detent plate 12 and fix it at each shift position, a detent spring 16 and a roller 17 provided at the tip thereof are provided.

As shown in FIG. 3, the top of the detent plate 12 is provided with four valleys provided between the pair of inner wall surfaces 18 and 19 corresponding to the P position, the R position, the N position, and the D position. The valley 20 located at the end of them corresponds to the P position.

When the shift lever (not shown) in the vehicle interior is positioned in the "P" position, a signal for operating the electric actuator M from an electronic control device (not shown) is used to lock the parking to prevent the rotation of the output shaft. Is output. FIG. 2 shows a state when the shift position is the P position. In this state, the parking lock pole 15 locks the parking gear 14, and the rotation of the drive shaft of the vehicle is hindered. From this state, when the shaft 11 is rotated in the direction of the arrow C shown in FIG. 2 by the electric actuator M that receives the signal for operation from the electronic control device, the rod 13 is shown in FIG. 2 via the detent plate 12. It is pushed in the direction of arrow A, and the parking lock pole 15 is pushed down in the direction of arrow B shown in FIG. 2 by retracting the taper member 21 provided at the tip of the rod 13.

As the detent plate 12 rotates, the valley located at the end of the four valleys provided at the top of the detent plate 12 corresponding to the P position, the R position, the N position, and the D position, that is, shown in FIG. The roller 17 of the detent spring 16 in the valley 20 at the P position gets over the mountain 22 and moves to one of the other valleys, that is, the non-P position 23 (see FIG. 3). The roller 17 is provided on the detent spring 16 so as to be rotatable around its axis. When the detent plate 12 rotates in the C direction until the roller 17 reaches the non-P position 23, the parking lock pole 15 is pushed down to a position where it does not mesh with the parking gear 14. As a result, the output shaft of the transmission and the drive wheels (not shown) connected to the output shaft are not mechanically fixed, and the shift position is switched to the non-P position. When the shaft 11 is rotated in the D direction by the electric actuator M, the shift position is switched to the P position by the reverse operation of the above operation.

The base of the outer lever 7a is fixed to the end of the shaft 11 of the parking lock mechanism 7, and the first inner cable 10a of the operation cable 8 is connected to the tip of the outer lever 7a. When the shift position is the P position, the operating lever 6 is operated in the direction of arrow E in FIG. 2, so that the outer lever 7a is operated in conjunction with the direction of arrow F. At this time, since the outer lever 7a rotates integrally with the shaft 11, the shaft 11 also rotates in the direction of the arrow C in FIG. 2 together with the operation of the outer lever. Since the detent plate 12 rotates with the rotation of the shaft 11, the detent plate 12 can be rotated by operating the operating lever 6 after all. In this way, the parking state in which the detent plate 12 rotates, the rollers 17 move to the non-P position 23, and the rotation of the wheels is locked can be manually released without using the electric actuator M.

The housing 26 can be disassembled, and in the disassembled state, an operator can access the pin 25a and the receptacle 25b to connect and disconnect the pin 25a and the receptacle 25b. The housing 26 is configured to be fixed to the rear support member 2a of the chassis 2 by the bracket 27. The bracket 27 is preferably fixed to the rear support member 2a via a rubber mount for damping (not shown). The cable connection mechanism 24 constitutes a support mechanism configured to support the outer sheath 9 on the chassis 2.

As shown in FIG. 4, the pin 25a integrally fixed to the first inner cable 10a has a substantially cylindrical main body 31, a small-diameter cylindrical neck 32 provided at the tip thereof, and a large-diameter short body. It has a cylindrical head 33. On the other hand, the slit tackle 25b integrally fixed to the second inner cable 10b is generally a rectangular parallelepiped, and has a width in which only the groove 34 in which the head 33 of the pin 25a is accommodated and the neck 32 of the pin 25a can pass through and the head 33 cannot pass through. It has a slit 35 of.

The housing 26 has a base 36 and a cap 37. The base 36 has a substantially cylindrical main body 39 and a mounting portion 40 extending in two directions from the base portion thereof. The cap 37 has a substantially bottomed cylindrical shape, and its open end is removably coupled to the main body 39 by a fixing means (not shown).

The cable connection mechanism 24 can be disassembled by inserting the head 33 of the pin 25a into the groove 34 of the receptacle 25b to connect the pin 25a and the receptacle 25b, and fitting and fixing the cap 37 to the base 36. Assembled to. In the assembled state shown in FIG. 4, the receptacle 25b is slidable in the longitudinal direction inside the cap 37.

Again, in FIG. 1, a connection switching mechanism 50 is further provided in the middle of the operation cable 8. The connection switching mechanism 50 includes an engaging piece 51 provided at the end of the third inner cable 10c and a cylindrical housing 52. A cylindrical portion 53 having an inner diameter through which the engaging piece 51 does not pass is provided at the end of the housing 52 on the operating lever 6 side, and a compression spring 54 is arranged on the outer circumference of the cylindrical portion 53. The engaging piece 51 is always urged toward the side opposite to the operating lever 6 (that is, the parking lock mechanism 7 side). The engaging piece 51 corresponds to the first connector in the present invention, and the cylindrical portion 53 corresponds to the second connector in the present invention. Brackets 55 are provided in order to maintain a distance in the front-rear direction that sandwiches the connection switching mechanism 50, that is, in the longitudinal direction of the operation cable 8, and an intermediate outer sheath 9b and a lever-side outer sheath 9c are provided at both ends of the bracket 55. Is being struck. The other end (left end in FIG. 1) of the lever-side outer sheath 9c is abutted against the abutting plate 43. The operation lever 6, the operation cable 8, the cable connection mechanism 24, and the connection switching mechanism 50 constitute the parking lock operation device according to the present invention. The combination of the first inner cable 10a and the second inner cable 10b corresponds to the lock mechanism side cable in the present invention, and the third inner cable 10c corresponds to the lever side cable in the present invention.

In the vehicle 1 according to the first embodiment configured as described above, before the operation lever 6 is operated, a space is created between the engaging piece 51 and the cylindrical portion 53 due to the restoring force of the compression spring 54. It is formed. Therefore, an incompletely connected state in which the transmission of the traction force from the engaging piece 51 to the cylindrical portion 53 is suppressed is established.

From this state, when the operating lever 6 is operated in the E direction in FIG. 1, the compression spring 54 is compressed and the engaging piece 51 and the cylindrical portion 53 come into contact with each other. Then, when the operating lever 6 is further operated in the E direction in FIG. 1, the traction force from the third inner cable 10c passes through the second inner cable 10b and the first inner cable 10a, and the outer lever of the parking lock mechanism 7 is used. It is transmitted to 7a. That is, after the operating lever 6 is operated, a connected state is established in which the traction force is transmitted from the engaging piece 51 to the cylindrical portion 53 to the extent that the parking lock mechanism 7 can be released from the parking state by the operating lever 6. .. In this connected state, the transmission of traction is promoted more than in the incompletely connected state.

Further, after the operation lever 6 is operated, a connected state is established in which the traction force is transmitted from the engaging piece 51 to the cylindrical portion 53 to the extent that the parking state of the parking lock mechanism 7 can be released by the operation lever 6. Therefore, the traction force required for operating the parking lock mechanism 7 is transmitted. That is, according to the present embodiment, it is possible to suppress the transmission of vibration during normal operation in which the operation lever 6 is not operated, and to execute the operation during manual release when the operation lever 6 is operated without any trouble.

Further, if the connection switching mechanism 50 is provided in the area between the cable connection mechanism 24 (support mechanism) and the transmission case 4 in the operation cable 8, the vibration of the transmission case 4 acts remarkably in the area. Therefore, even in the normal state when the operation lever 6 is not operated, the engagement piece 51 and the cylindrical portion 53 in the connection switching mechanism 50 collide with each other due to the vibration of the operation cable 8, or the compression spring 54 vibrates. It may be compressed to such an extent that it can be significantly transmitted to some extent, and this may be transmitted to the operating lever 6 as noise or vibration. On the other hand, in the present embodiment, the connection switching mechanism 50 is not the area between the cable connection mechanism 24 (support mechanism) and the transmission case 4, but the traction force from the operation lever 6 to the cable connection mechanism 24 (support mechanism). Since it is provided in the transmission path, the transmission of the vibration of the transmission case 4 to the connection switching mechanism 50 is suppressed, and therefore, the influence of the vibration of the transmission case 4 on the suppression of the vibration transmission in the connection switching mechanism 50 is suppressed.

That is, after the operation lever 6 is operated, a connected state is established in which the traction force is transmitted from the female connector 81 to the male connector 82 to the extent that the parking state of the parking lock mechanism 7 can be released by the operation lever 6.

When the restoration worker disconnects the female connector 81 and the male connector 82 again when the cable connection mechanism 80 is disassembled, that is, after the parking lock is manually released, the restoration worker removes the cap 92 of the housing 91 from the base 36. As shown in 8, the flexible arm 85 of the female connector 81 is exposed from the tip of the cap 92, and the male connector 82 is slid in the width direction (W1-W2 direction) to form the female connector 81 and the male connector 82. Can be easily separated.

As described above, according to the fourth embodiment, while suppressing (blocking / prohibiting) the transmission of vibration during normal operation in which the operating lever 6 is not operated, the operation at the time of manual release in which the operating lever 6 is operated is performed. It can be executed without any trouble. Further, since the pair of flexible arms 85 and the cap 92 that closes the side of the space between them are provided, the female connector 81 and the male connector 82 can be easily separated when the cable connecting mechanism 80 is disassembled. ..
