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 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. 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. In addition, there is no special stopper for the spring rod 2, and a separate stopper must be provided as needed.

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 adjust its position, can reasonably transmit operating force, and has a built-in stopper.

The configuration of the present invention that achieves such an object includes an arm whose distal end is connected to a shift lever, an arm disposed along the select movement direction of the shift lever, a proximal end of the arm attached to the distal end, and an intermediate portion. The outer pipe is connected to the inner periphery of the proximal end of the outer pipe via a spline, and the axial end of the removed portion of the outer pipe comes into contact with the inner periphery of the outer pipe. a rotary pipe rotatably supported on a mounting base so as to define an axial moving end of the rotary pipe; a push-pull wire for shifting that operates the shift lever in the shift movement direction by rotating a pipe; and a push-pull wire for shifting that passes through the rotary pipe and is connected to the outer pipe and is operated by an actuator to move the outer pipe to the inner side. The present invention is characterized by comprising a selection push-pull wire that operates the shift lever in the selection movement direction by moving it in the axial direction with respect to the pipe.

Therefore, when the actuator for moving the outer pipe is actuated to operate the push-pull wire for selection, the outer pipe connected to the push-pull wire for selection moves along the axial direction of the rotating pipe to which the spline is fitted. As the outer pipe moves, the shift lever moves in the selection direction via an arm attached to the outer pipe.
At this time, the stroke end of the outer pipe relative to the rotating pipe is defined by the axial end of the removed portion of the outer pipe.

Furthermore, when the actuator for rotating the outer pipe is actuated to operate the push-pull wire for shifting, the outer pipe is spline-fitted to the rotating pipe via a connecting member connected to the push-pull wire for shifting. At the same time, 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, for assembly, the rotary pipe 24 is supported by the support plate 25 after connecting the outer pipe 32 and the rotary pipe 24, or the base end 32a of the outer pipe 32 is cut in half and the ball spline 33 is assembled. It is preferable that the base end 32a of the outer pipe 32 is fixed to the ball spline 33 after the rotary pipe 24 equipped with the rotary pipe 24 is supported by the support plate 25. 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 surface of the tip 32a,
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, 40b are inserted into the levers 38a, 38b, and the countersunk screws are screwed into the fixing disk 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 rotating pipe 24 via the coupler 30 and the shift connecting member 28, and the rotating 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. Further, since the middle portion of the outer pipe 32 is removed, the axial end face of the removed portion 32d comes into contact with the shift connecting member 28 or the support plate 25 at that location, and acts as a stopper. Note that the base end surface of the outer pipe 32 is connected to the other support plate 25.
When the outer pipe 32 is brought into contact with it to act as a stopper against the rightward movement of the outer pipe 32 in FIG.
The removed portion 32d of the outer pipe 32 is attached to the tip portion 32b.
It is possible to extend it up to. Furthermore, since the middle part of the outer pipe 32 is removed,
The operation of connecting the inner cable 26b of the selection push-pull wire 26 to the outer pipe 32 is easy. In addition, since the outer pipe 32 can be moved in the axial direction via the ball spline 33,
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, 3
8b to screw together the countersunk screws 40a and 40b fitted into the countersunk screw holes 38d and 38e,
A tightening bolt 39 screwed into the lever 38a is brought into contact with the fixed disc 34 and tightened. This tightening bolt 3
When tightening 9, the lever 38a is raised at its connecting portion, and the uneven stepped portion 38c tightens both levers 38a,
38b will be tilted at the same time. This movement creates a force that presses 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 gutter-like structure in which the tube wall is removed in the axial direction not only at the intermediate portion but also at the tip and base ends. 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.
A transmission operating device capable of rationally transmitting operating force to a shift lever and having a built-in stopper is obtained.
