Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transmission operating device for mechanically operating a transmission shift lever, 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 to 3 are for example
This type of conventional device disclosed in Japanese Patent No. 55-22520 and the like is shown. 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 fairly large device, installation requires the removal of the car seat, which is not only cumbersome, 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 to install it. In this case, manual operation was forced.
Also, the interior of the car was often dirty due to oil leaks. Moreover, since the direction of movement of the spring rod 2 does not completely match the direction of movement of the shift lever 1, the transmission of operating force is not rational.

SUMMARY OF THE INVENTION In view of the above-mentioned prior art, it is an object of the present invention to provide a mission operating device that is easy to position, can be easily attached to a seat, and can reasonably transmit operating force.

The configuration of the present invention that achieves this object includes a rotating pipe rotatably supported on a mounting base, an outer pipe connected to the outer periphery of the rotating pipe via a spline, and an outer pipe attached to the outer periphery of the rotating pipe. a first push-pull wire connected to the coupling member and operated by an actuator to rotate the outer pipe together with the inner pipe; A second push-pull wire connected to the outer pipe and operated by an actuator to move the outer pipe in the axial direction with respect to the inner pipe, and an arm attached to the outer pipe and connected to the shift lever. It is characterized by

Therefore, when the outer pipe movement actuator is actuated to operate the second push-pull wire,
The outer pipe connected to this second push-pull wire moves along the axial direction of the rotary pipe to which it is spline-fitted, and as the outer pipe moves, the shift lever is moved through the arm attached to the outer pipe. Move in the select direction.

Further, when the actuator for rotating the outer pipe is actuated to operate the first push-pull wire, the outer pipe is spline-fitted with the first push-pull wire via a connecting member connected to the rotating pipe. The shift lever rotates in the shift direction via an arm attached to the outer pipe.

The present invention will be described below with reference to embodiments shown in the drawings.

4 to 6 show an embodiment of the present invention, FIG. 4 is a cross-sectional view showing the center and right side parts of the apparatus according to the embodiment, FIG. 5 is a cross-sectional view showing the left side part slightly enlarged, and FIG. FIG. 6 is a sectional view of the vicinity of the push-pull wire connecting member.

In Figures 4 to 6, 16 is a seat in the test vehicle;
17 is a rail of the seat, and 18 is a rail receiver on the floor 19. A mounting plate 20 is placed on the seat 16,
This mounting plate 20 is fixed onto the seat 16 by a jack-type tensioning device 21 between it and the floor 19 and a belt (not shown) between it and the backrest of the seat 16. A magnet 22 for adsorption is arranged on the mounting plate 20, and a mounting base 23 is screwed onto the upper surface of the magnet 22. 24 is a rotating pipe, and in this example, a ball spline groove 24a is formed on the outer periphery. This rotary pipe 24 is rotatably bridged between two support plates 25 on the mounting base 23. Reference numeral 26 denotes a select push-pull wire, the proximal end of which is connected to a select actuator (not shown), and the distal end thereof penetrating into the rotary pipe 24 . A coupler 27 is detachably attached to the side surface of one of the support plates 25 on the base end side of the rotary pipe 24, and the outer cable 26a of the selection push-pull wire 26 is fixed by this coupler 27. Reference numeral 28 denotes a shift connecting member, which in this example is fixed to the outer periphery of the rotary pipe 24 near the other support plate 25 . The tip of the inner cable 29b of the shift push-pull wire 29 is connected to the coupler 3 in this shift connecting member 28.
Connected via 0. The outer cable 29a of the shift push-pull wire 29 is connected and fixed to a guide tube attached to the mounting base 23 via a coupler 31 as well. 32 is an outer pipe, which in this example has a base end 32a and a tip end 32.
The lower half of the tube wall of the intermediate portion is removed, leaving part b (see reference numeral 32d). 33 is a ball spline, which is connected to the ball spline groove 2 of the rotary pipe 24.
A ball that fits into the ball 4a is stored in a storage box 33a. The ball spline 33 is the outer pipe 3
The outer pipe 32 is connected to the rotary pipe 24 by this ball spline 33. Therefore, assembly can be carried out by connecting the outer pipe 32 and the rotating pipe 24 and then supporting the rotating pipe 24 with the support plate 25, or by cutting the base end 32a of the outer pipe 32 in half and attaching the ball spline 33 to the rotating pipe 24. It is preferable to support the rotary pipe 24 equipped with the rotary pipe 24 on the support plate 25 and then fix the base end 32a of the outer pipe 32 to the ball spline 33. In this example, an annular recess 32e is formed on the inner periphery of the tip 32b of the outer pipe 32, leaving an edge 32c and extending to the deleted portion 32d, and the fixed disc 34 is rotatably inserted into the annular recess 32e. Ru. One side of the fixed disk 34 is in close contact with the inner wall of the end edge 32c of the outer pipe 32, and the other side is screwed into the connecting cylinder 35. This connecting tube 35 connects to a coupler 35 attached to the tip of the inner cable 26b of the select push-pull wire 26.
are rotatably connected. An end of an arm 37 connected to a shift lever (not shown) is attached to the tip 32a of the outer pipe 32. In this example,
A long hole 37a is formed in the arm 37 so that the arm 37 can be attached to the front side of the tip 32e.
This arm 37 has a plate-shaped lever 38 divided into two parts.
a and 38b are attached. This lever 38a, 3
8b is formed with uneven steps 38c that are in close contact with each other at the connecting portion, and each lever 3
Holes 38d and 3 for countersunk screws are provided at the ends of 8a and 38b.
8e is formed. Further, the lever 38a having a convex step on the side that contacts the arm 37 has a threaded hole into which a tightening bolt 39 can be screwed. Countersunk screws 40a and 40b are inserted into the levers 38a and 38b, and the countersunk screws are screwed into the fixed disc 34 through the long holes 37a. The tightening bolt 39 itself has a lock nut, and is screwed into the screw hole of the lever 38a to lock the fixing disc 3.
4.

In such a structure, the movements of each part for moving the arm 37 will be explained. In addition, arm 37
The tip of the shift lever is connected to the shift lever by an appropriate chucking device (not shown).

Now, when the selection push-pull wire 26 is operated, the inner cable 26b moves back and forth in the longitudinal direction. This movement of the inner cable 26b is caused by the coupler 36, the connecting tube 35, and the fixed disc 3.
4 to the outer pipe 32. The outer pipe 32 moves in the select direction along the rotary pipe 24 together with the ball spline 33, and thus the arm 37 moves in the select direction. Further, when the shift push-pull wire 29 is operated, the inner cable 29b moves vertically in the longitudinal direction. This movement of the inner cable 29b is transmitted to the spline 24 via the coupler 30 and the shift connecting member 28, and the rotary pipe 24 rotates. This rotation is transmitted to the outer pipe 32 via the ball spline 33, thereby causing the arm 37 to rotate in the shift direction. In this way arm 3
7 moves in the shift direction and select direction. In this case, since the movement in the shift direction is an arc movement, it matches the movement of the shift lever, and the operating force is transmitted rationally. Further, since the outer pipe 32 is connected to the rotary pipe 24 by a spline, the initial position of the arm 37 in the shift direction can be adjusted by selecting the fitting position of the spline, and can be adapted to various types of automobiles. Furthermore, since the middle portion of the outer pipe 32 is removed, the end face of the removed portion 32d is connected to the shift connecting member 28 or the support plate 2 at that location.
5 and acts as a stopper. Of course, the base end surface of the outer pipe 32 is also connected to the other support plate 25.
It comes into contact with and acts as a stopper. Furthermore,
Since the middle portion of the outer pipe 32 is removed, the work of connecting the inner cable 26b of the selection push-pull wire 26 to the outer pipe 32 is easy. Also, ball spline 3
3, the outer pipe 32 can be moved in the axial direction, so the initial position of the arm 37 in the selection direction can be adjusted.

On the other hand, when attaching and fixing the arm 37 to the outer pipe 32, the levers 38a, 38 are inserted into the fixing disk 34 fitted into the annular recess 32e through the elongated hole 37a.
The countersunk screws 40a and 40b fitted into the countersunk screw holes 38d and 38e are screwed together by b, and the tightening bolt 39 screwed into the lever 38a is brought into contact with the fixed disc 34 and tightened. This tightening bolt 39
To tighten the lever 38a, the lever 38a is raised at its connecting part, and the uneven stepped 38c is used to tighten both levers 38a, 3.
8b will be tilted at the same time. This movement creates a force that compresses the arm 37 against the edge 32c of the outer pipe 32, and the force is increased by the lever action at the countersunk screws 40a, 40b. As a result, the attachment of the arm 37 becomes strong. Incidentally, the inclination of the levers 38a and 38b is the same as the hole 38d for the countersunk screw.
It will escape at the plate part of 38e. With such an arm mounting structure, when installing the arm 37, it can be adjusted to a suitable fixing position using the elongated hole 37a, and the shift direction of the arm 37 can be adjusted by rotating the fixing disk 34 within the annular recess 32e. The initial position can be adjusted. The installation work for the arm 37 requires removing the middle part of the outer pipe 32.
The installation is as simple as the selection push-pull wire 26.

Furthermore, the above-mentioned transmission operating device has a compact shape since the rotary pipe 24 and the outer pipe 32 are the main members, so it can be easily installed on the seat 16, and its position relative to the shift lever can be adjusted using the seat 16. It is also possible to do this by sliding. Of course, the position of the mounting base 23 can also be selected using the magnet 22.

It should be noted here that the outer pipe 32 may be a simple pipe without a deleted portion. In this case, the rotary pipe 24 is cantilever-supported by the support plate 25, but assembly is simple. Moreover, the mounting structure of the arm 37 may be any other structure other than the structure shown in the drawings. Furthermore, it is convenient to provide a scale indicating shift and selection, such as a cross-shaped figure, on the outer surface of the outer pipe 32, so that the user can immediately know in which position the shift lever is being operated. Further, the actuator connected to each push-pull wire 26, 29 can be installed either inside or outside the vehicle as required.

As explained above, according to the present invention, the shape is compact and can be easily installed on the seat, and the position can be easily adjusted with the shift lever of various automobiles.
Moreover, a transmission operating device is obtained which can rationally transmit operating force to the shift lever.
