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.

In the case of bench testing of automobiles, a transmission operating device that can mechanically operate the transmission shift lever is required for program operation and remote control of the transmission. 1 to 3 are examples of conventional devices. This mission operating device is a floor type device. The tip of the shift lever 1P is connected to the spring rod 2 via the link ball.
The spring rod 2P is connected via a link to a shift actuator 3P and a selection actuator 4P disposed substantially perpendicular to the shift actuator 3P.

The structure of the link consists of an output shaft 5P of the shift actuator 3P, and a swinging arm 8P connected to the output shaft 5P, with a uniball 6P in the middle, and a uniball 7P at the tip connected to the spring rod 2P. , and the output shaft 9P of the select actuator 4P and the universal joint 10P at the tip.
The swing arm 11P is connected to the base end of the spring rod 2P. Also, 12P, 1
3P is an oil supply pipe and oil drain pipe that respectively supply and discharge oil to the actuator, 14P
is a servo valve, and 15P is a short-circuit solenoid valve. Therefore, according to the above structure, the shift actuator 3P is actuated to swing the tip of the spring rod 2P in the shift direction shown in FIG. 1, thereby causing the shift lever 1P to perform a shift operation. Furthermore, when the selector actuator 4P is actuated to move the spring rod 2P in the axial direction, the shift lever 1P is caused to perform a select operation.

What we will focus on here is the fixation of the tip of the shift lever 1P to one end of the spring rod 2P. Since this part is connected by a link ball, the position cannot be adjusted. In addition, even though the position can be adjusted by expanding and contracting the spring rod 2P, the position cannot be adjusted because the spring rod 2P can only move in the longitudinal direction, and the rods in the shift direction and select direction are connected in the middle. Naturally, there are limits. In particular, the length and direction of movement of the shift lever 1P vary depending on the type and model of the vehicle. For this reason, when the apparatus shown in FIGS. 1 to 3 has been installed, in extreme cases it may be necessary to reinstall it.

In addition, the limit of this position adjustment creates the risk of applying excessive force to the shift lever 1P, which rotates vertically and horizontally around the base end, and also causes the movement of the swing arms 8P, 11P, and spring rod 2P. does not necessarily match the amount of movement of the rotating shift lever 1P, and since the operating force of the actuators 3P and 4P is difficult to be transmitted efficiently, there is a risk that an unreasonable force will be applied to the shift lever 1P.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a transmission operating device that avoids the above-mentioned drawbacks, allows for versatile position adjustment, and prevents excessive force from being applied to the shift lever.

The configuration of the present invention that achieves this object includes a rotating pipe rotatably supported on a mounting base, a shift push-pull wire for rotationally driving the rotating pipe in the circumferential direction, connected to the rotating pipe, A half cylinder which can move in the axial direction of the rotary pipe and rotates integrally with the rotary pipe in the circumferential direction thereof and has a lid at its tip is provided on the outer periphery of the rotary pipe via a spline, while a bolt is attached to the outer circumference of the rotary pipe. an arm for operating a shift lever by forming a long hole to be fitted into the arm; and a fixed disc provided inside the lid of the half-split cylinder and into which the bolt is screwed;
The arm is bolted to the tip of the halved cylinder across the lid, and a select push-pull wire that passes through the rotary pipe is connected to the fixed disc, so that the arm can be moved in the axial direction of the rotary pipe and It is characterized by being configured to operate in the circumferential direction.

Embodiments of the present invention will now be described with reference to FIGS. 4 to 6. A mounting base 2 is fixed and fixed on the seat 1 in the test vehicle by a tension device (not shown).
Supported. A magnet 3 for adsorption is arranged on the mounting base 2. magnet 3
A mounting plate 4 is screwed to the upper end of the holder. Two support plates 5 are planted on the mounting plate 4 and fixed with bolts. A rotary pipe 6 in which a spline groove is formed is rotatably bridged between the support plates 5. A selector push-pull wire 7 passes through the rotary pipe 6. A selector push-pull wire 7 is attached to one end of the rotary pipe 6 and to the side of one support plate 5.
A coupler 8 for fixing the outer cable is detachably attached. A shift connecting member 9 is fixed to the outer periphery of the rotary pipe 6 near the other support plate 5. In addition, a spline 1 is provided on the outer periphery of the rotating pipe 6.
0 is formed to be movable in the axial direction of the rotary pipe 6. The tip of the inner cable of the shift push-pull wire 11 is connected to the shift connection member 9 via a coupler 12 . A storage box 10a containing balls that fit into the ball spline grooves of the rotary pipe 6 is connected to a half-tube 13, which is a cylindrical half-split in the axial direction. The tip of the half cylinder 13 has a recess 13a in the inner circumferential wall and has a flat cylindrical lid 1.
3b. Recessed portion 13a within lid portion 13b
A fixed disk 14 is rotatably fitted into the. One side of this fixed disk 14 is in close contact with the inner wall of the lid portion 13b. The other side of the fixed disk 14 is screwed into a connecting cylinder 15. A couple 16 attached to the tip of the select push-pull wire 7 is rotatably connected to the connecting tube 15. The end of an arm 17 connected to a shift lever (not shown) is attached to the front side of the lid portion 13b, which is the tip of the half-split cylinder 13. This arm 17 has a long hole 17a formed therein. Two bolts 18 are fitted into the elongated hole 17a, and the bolts 18 pass through the lid portion 13b and are tightened into the fixed disc 14. Therefore, the arm 17 is fixed to the lid portion 13b and eventually to the half cylinder 13 by the bolt 18 and the fixing disk 14.

In such a structure, the movements of each part for moving the arm 17 will be explained. When you operate the select push pull wire 7, this wire 7
The inner cable moves along the longitudinal direction. The movement of this inner cable is as follows: coupler 16, connecting tube 1
5. It is transmitted to the arm 17 via the fixed disk 14. The arm 17 moves in the selection direction together with the spline 10. Further, when the shift push-pull wire 11 is operated, this inner cable moves up and down. This vertical movement of the inner cable is transmitted to the rotating pipe 6 via the coupler 12 and the shift connecting member 9. This rotation of the rotary pipe 6 causes the half tube 13 and the lid portion 13b to rotate via the spline 10. Therefore, the arm 17 moves in the shift direction.

The length and moving direction of the shift lever vary depending on the type of automobile, but the arm 17 is connected to the cover 1.
3b, the suitable fixing position of the arm 17 can be adjusted using the elongated hole 17a attached to the arm 17, and the recess 13 in the lid 13b
Since the fixed disk 14 can rotate within a, the arm 1
The rotational position of the lid part 13b relative to 7 can also be adjusted, and the rotary pipe 6 can be moved along the spline 1 along the axial direction.
0 is movable, the position of the half-split cylinder 13 relative to the arm 17 can also be adjusted. These adjustments can be made by attaching and detaching the bolts 18 even after the device has been installed.

According to the present invention, as embodied in the above embodiments, a push-pull wire for selection and a push-pull wire for shift are arranged at right angles thereto, and the selection operation is performed by moving the half cylinder by the spline 10. Due to the expansion and contraction, the shift operation can be performed by both the rotation of the spline 10 and the rotation of the half-split tube.Moreover, the long holes in the arm and the fixing disk in the lid allow bolts to be fixed as appropriate. In addition, even if the shift lever changes, it is possible to make a large adjustment to the shift lever. Furthermore, with this adjustment, it is possible to avoid applying excessive force to the shift lever, and the operating force is not wasted, and it can be moved not only in a straight line but also on a spline. The rotation of the shift lever can be matched with the rotation of the shift lever. Therefore, regardless of the car model or model, it can be adjusted even after the device is installed, and unreasonable force on the shift lever can be reduced, resulting in a long life.
