Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transmission operating device for mechanically operating a shift lever of a column shift type transmission, and is particularly useful for bench testing and simulation of automobiles.

For bench testing of automobiles, a transmission operating device that can mechanically operate a transmission shift lever is required for programming and remote control of the transmission. Figures 1-3 show prior art devices of this type. In the figure, 1 is a shift lever, 2 is a spring rod that connects the upper end of the shift lever 1 with a ball joint 2' at its tip, and 3 and 4 are actuators for shift operation arranged at almost right angles to each other, and a selector lever. This is an actuator for operation.

The output shaft 5 of the shift operation actuator 3 has a universal joint 6 in the middle, and a swing arm 8 whose tip is connected to the spring rod 2 by a uniball 7.
The base of the shaft is attached to the shaft. On the other hand, the output shaft 9 of the select operation actuator 4 has a universal joint 10 at its tip.
A swing arm 11 connected to the base end of the spring rod 2 is pivotally attached. In addition, 12 and 13 are an oil supply pipe and an oil drain pipe for supplying and discharging oil to the actuator, respectively, 14 is a servo valve,
15 is a short circuit solenoid valve.

Therefore, according to the above structure, by operating the shift operation actuator 3, the tip end side of the spring rod 2 can be swung in the longitudinal direction in FIG. 1, thereby causing the shift lever 1 to perform a shift operation. Further, when the select operation actuator 4 is operated, the spring rod 2 is moved in the axial direction, and the shift lever 1 can be caused to perform the select operation.

However, according to the conventional transmission operation device, the two actuators 3 and 4 for shift operation and selection operation are installed independently from each other on a plane, so the installation area becomes large and
Adjusting the placement position is also difficult. Furthermore, since it is a large-scale device, the car seat must be removed to install it, which is not only complicated, but also especially in bench seat type passenger cars and small trucks where the passenger seat is integrated with the driver's seat. It was impossible. In this case, manual operation was forced.
Also, the interior of the car was often dirty due to oil leaks.

It will be done by removing it from 22. Therefore, in this embodiment, an attachment/detachment cylinder 46 is loosely fitted into the support cylinder 24, so that when the operation cylinder 28 is pushed down sufficiently beyond the normal stroke, it is indicated by the two-dot chain line in FIG. As a result of the ring plate 30 pressing down the detachable cylinder 46, the sleeve 31b is pushed down by the detachable cylinder 46.

In the device of this embodiment having the above structure, the mounting plate 2
2. The support cylinder 24 and the bearings 25, 25a form a support member, and this support member as a whole supports the spline inner cylinder 27 so that the spline inner cylinder 27 is at the center of rotation of the shift lever 17 in the shift direction, that is, the shift rod 45. Insert U bolt 2 so that it is coaxial with the axis of
3, it is fixedly installed on the steering wheel 18.
With the male coupler 39a inserted into the female coupler 39 in this case, the shift cable 20 connects one end of the inner cable 20a to the spline inner cylinder 27.
The shift arm 37 is connected to the shift arm 37 by bolting a link ball 38. The operating tube 28 is connected to the connecting tool 29
With the male couplers 29a, 31a and the female couplers 29c, 31c disengaged from each other, the position of the operating arm consisting of the first and second operating arms 41, 42 is changed to the position of the shift lever 17 ( For example, it is fitted into the spline inner cylinder 27 in accordance with the neutral position. The coupler male body 31a at the tip of the inner cable 16a of the select cable 16 is
The attachment/detachment cylinder 46 is pressed down with the operation cylinder 28 and engaged with the coupler female body 31c. Further, the male coupler body 29a at the tip of the outer cable 16b of the select cable 16 is engaged with the female coupler body 29c by simply pushing down the sleeve 29b by hand. Next, the connector 44 of the second operating arm 42 is connected to the lever presser member 50 and the lever presser plate 52, which have been removed from the spherical bearing 49 in advance, with the lever presser member 50 and the lever presser plate 52 first secured to the shift lever 17 with the bolts 53. is inserted and fixed into the spherical bearing 49 and attached to the shift lever 17.

The apparatus of this embodiment having such a configuration operates as follows. Now, assume that the shift lever 17 is in the neutral position as shown by the solid line in FIGS. 5 and 7. At this time, the selection actuator 34
Assume that the other end of the inner cable 16a of the select cable 16 is moved back and forth in the direction of arrow F by operating the select cable 16 appropriately. In the select cable 16, the inner cable 16a is restricted from moving in the axial direction by the connector 31 at one end, and the outer cable 16b is fixed by the fixture 33 at the other end. Due to the change in the route of the select cable 16 at
As a result of the expansion and contraction between the connecting member 29 at the tip of the outer cable 16b and the free end of the outer cable 16b, the operation cylinder 28 moves up and down as shown by arrow D, and the shift lever 17 is moved in the selection direction A. On the other hand, assume that the shift actuator 36 is operated to move the other end of the inner cable 20a of the shift cable 20 back and forth in the direction of arrow G. Since the shift cable 20 has only the outer cable 20b fixed at both ends, one end, which is the free end of the inner cable 20a, moves in conjunction with the other end, thereby causing the spline inner cylinder 27 to move along with the shift arm 37 in the direction indicated by the arrow. As a result of rotating in the J direction, the operation cylinder 28 moves into the first and second operation arms 41 and 42.
The shift lever 17 rotates in the shift direction B together with the shift lever 17 in the direction of arrow E. In this case, the support tube 24
is arranged on the rotation center of the shift lever 17, so that the rotation center of the spline inner cylinder 27 and the operation cylinder 28, and in turn the rotation center of the first and second operation arms 41, 42, and the rotation center of the shift lever 17 are aligned. The center of rotation in the shift direction coincides, and the operating force of the operating arm is smoothly transmitted to the shift lever 17 without loss. Also,
One end of the shift cable 20 is rotatably supported by a female coupler 39 and a male coupler 39a, and the inner cable 20a is connected to the shift arm 37 via a link ball 38, so that the front and rear of the inner cable 20a The movement is shift arm 37
The rotation is smoothly converted into the rotation of Furthermore, since the operating force is transmitted from the second operating arm 42 to the shift lever 17 via the spherical bearing 49, it is smooth in both the select direction A and the shift direction B. Furthermore, both the connectors 29 and 31 have a coupler female body 29.
Since the coupler male bodies 29a and 31a are rotatable relative to c and 31c, the select cable 16 is not twisted even if the operation tube 28 is rotated.

FIG. 10 shows another implementation mode of the device of this embodiment.

The present invention has been described in detail with reference to the embodiments above, and the mission operating device according to the present invention operates the shift lever of a column shift type transmission, and includes an inner cylinder having a spline on the outer periphery (spline inner cylinder). , an outer cylinder (operating cylinder) that is removably spline-fitted to the inner cylinder, a support member that has a bearing part that pivotally supports the inner cylinder and is attached to the steering wheel, and an inner cylinder that is rotatably supported by the bearing part. a mounting device for mounting the support member to the steering wheel at a position where the axis of the cylinder coincides with the center of rotation in the shift direction of the shift lever; and a mounting device for mounting the support member on the base end of the inner cylinder so as to rotate integrally with the inner cylinder. a shift actuator connected to the shift arm by a shift cable having an outer cable and an inner cable to rotate the shift arm, and an outer cable and an inner cable, one end of which is connected to the outer cylinder. a select cable that is inserted into the select cable while the other end of the outer cable is fixed; a connector that integrally connects one end of the outer cable of the select cable to the outer cylinder in the axial direction; and a connector that is attached to the support member. a connector for connecting one end of the inner cable of the select cable; a select actuator connected to the other end of the inner cable of the select cable to move the outer cylinder in the axial direction; The operating arm is provided in a protruding manner and is connected to the shift lever via a shift lever connector. Therefore, both the shift link mechanism and the select mechanism have a cylindrical structure, making it simple, compact, and lightweight with fewer parts.Moreover, both mechanisms are coaxially combined, making it even simpler, lighter, and reducing costs. I was able to figure it out. Further, since both mechanisms are removably connected by a spline, the installation work is easy, and the positioning of the operating arm and the shift lever can be easily achieved by the relative positioning of the inner cylinder and the outer cylinder. Further, since the relationship between the inner cylinder and the outer cylinder is relative, the direction in which the shift cable connecting the inner cylinder and the shift actuator is drawn out can be freely selected 360 degrees. Furthermore, since the rotation center of the operating arm coincides with the rotation center of the shift lever, the shift lever can be operated smoothly.

As specifically explained above, the present invention is particularly useful for mechanical operation of a transmission in bench tests and simulations of automobiles. Also,
Because it is small and lightweight, and easy to install and adjust, the device of the present invention can be easily installed in a narrow space such as a driver's seat in a car, and in particular can be installed on the steering wheel of a column shift type vehicle. It can be used in all car models regardless of the seat type, such as bench seats or separate seats.
