Description

[Detailed Description of the Invention] The present invention relates to a transmission operating device that mechanically operates a transmission shift lever, and is particularly useful for use in bench tests and simulations of automobiles.

An example of a conventional mission operating device is shown in FIGS. 1 to 3. This mission operating device is a floor type device. The tip of shift lever 1P is connected to spring rod 2 via a ball joint.
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 a shift actuator 3P, a swing arm 8P connected to the output shaft 5P, a universal joint 6P in the middle, and a unipole 7P connected to a spring rod 2P at the tip. It also consists of an output shaft 9P of the select actuator 4P and a swing arm 11P whose tip is connected to the base end of the spring rod 2P by a universal joint 10P. Also, 12P, 13
P designates an oil supply pipe and an oil discharge pipe for supplying and discharging oil to the actuator, respectively, 14P a servo valve, and 15P 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. Further, when the select 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.

However, in the case of a transmission operating device with such a structure, the actuator, which is the power source, is also installed inside the vehicle under test, making it heavy and difficult to install and remove. The interior of the vehicle is often contaminated by leakage of the air, and furthermore, position adjustment is required during installation. However, since the select actuator 4P and the shift actuator 3P are arranged independently on almost the same plane at right angles, If the installation area becomes larger, it is possible to adjust the front and back and left and right by moving inside the elongated hole.
There are disadvantages such as the vertical adjustment using bolts is troublesome and difficult, and the installation work is very complicated because the seat must be removed.

The above-mentioned drawbacks are related to the floor-type transmission operating device, but there is no column-type transmission operating device that is more suitable than the conventional one, and even if the floor-type device is applied, the above-mentioned drawbacks cannot be eliminated, and the oil In addition to contamination due to leakage and the difficulty of attaching and detaching due to the large weight, it is especially troublesome and difficult to adjust the installation position related to the position of the shift lever. There are serious problems due to the lifting of the mission equipment due to its location in the space.

Therefore, in view of the above-mentioned drawbacks, the present invention provides a suitable column-type transmission operating device, and at the same time, it solves the problems such as difficulty in attaching and dismounting work, troublesome and difficult position adjustment, and oil leakage, etc. when applying a floor type. The purpose of the present invention is to provide a mission operating device that eliminates the

Next, the selection cable 16 will be mainly described. One end of the select cable 16 is connected to the coupler 2
The outer cable 16b of this select cable 16 is fixed to the male coupler body 29a of the coupler 29, while the inner cable 16a is fixed to the male coupler body 31a of the coupler 31. . The selection cable 16 is attached to and detached from the operating mechanism section 24 using a sleeve 29 which is biased in the axial direction and loosely fits around the outer periphery.
coupler female body 29c, 31c having b, 31b
The engagement with the female coupler bodies 29c, 31c is made by the male coupler bodies 29a, 31a, which are released by the movement of the sleeves 29b, 31b in the opposite direction. Especially when removing the outer cable 16b
The connection between the inner cable 16a and the female coupler body 31c and the mounting plate 22 can be released by one-touch operation of the sleeve 29b, but the connection between the inner cable 16a and the female coupler body 31c and the mounting plate 22 can be released when the coupler 31 is inside the support tube 24a. Therefore, one-touch operation is not possible in this state, and the entire coupler 31 must be removed from the mounting plate 22. In this embodiment, when the attachment/detachment cylinder 46 is loosely fitted into the support tube 24a and the operating tube 28 is pushed down sufficiently beyond the normal stroke as shown by the two-dot chain line in FIG. As a result of pushing down the cylindrical body 46, the sleeve 31b is moved by the detachable cylindrical body 46, so that the female coupler body 31c and the male coupler body 31a can be engaged or disengaged.

The assembly of the mission operating device of this embodiment will be explained. The mounting plate 22 is fixedly mounted on the steering wheel 1 with U bolts 23 so that the axis of the operating mechanism section 24 erected on the mounting plate 22 is the same as the axis of the shift rod 45. The shift cable 20 is connected to the inner cable 20a and the spline inner cylinder 2 with the coupler male body 39a inserted into the coupler female body 39.
The shift arm 37 protruding from the link ball 38 is connected to the shift arm 37 by bolting the link ball 38. The operation tube 28 is connected to the couplers 29 and 31 of the same operation mechanism section 24.
Respective coupler male body 29a, 31a and coupler female body 2
9a and 31c, the operating arm 41 and the second operating arm 42 are fitted into the spline inner cylinder 27 with the positions of the operating arm 41 and the second operating arm 42 aligned with the neutral position of the shift lever 4. The coupler male body 31a at the tip of the inner cable 16a of the select cable 16 has an operation tube 28 and is connected to the attachment/detachment tube 46.
is fitted into the coupler female body 31c in a depressed state. Moreover, the coupler male body 29a at the tip of the outer cable 16b of the select cable 16 is connected to the sleeve 29.
By pushing down b, it is fitted into the coupler female body 29c. The connector 44 of the second operating arm 42 is connected to the shift lever 4 by attaching the lever pressing member 50 and the lever pressing plate 52, which have been removed from the spherical bearing 49 in advance, with a bolt 53.
The shift lever 4 is gripped by inserting and fixing the lever pressing member 50 into the spherical bearing 49 in a state where it is clamped to the lever.

Now, the operation in this embodiment will be explained here. The shift lever 4 is now in the position shown in Figures 5 and 7.
When in the neutral position indicated by the solid line in the figure, the select actuator 34 is actuated to connect the inner cable 16 of the select cable 16.
When the other end of a is moved back and forth as shown by arrow F (see Fig. 4), the inner cable 16a is fixed by the coupler 31 at one end of the select cable 16, and the outer cable 16b is fixed by the fixing device at the other end. 33, the coupler 31
The length of the cable between the and the fixture 33 changes, and the coupler 29 at one end of the outer cable 16b, which is the free end, moves accordingly, resulting in the arrow D (see Fig. 4).
The operation barrel 28 moves up and down as shown in FIG. 7, and the shift lever 4 is moved in the selection direction as shown by arrow M (see FIG. 7). On the other hand, when the shift actuator 36 is operated to move the other end of the inner cable 20a of the shift cable 20 back and forth as shown by arrow G (see Figure 4), the outer cable 20b of the shift cable 20 is fixed at both ends. Because it has been
One end side, which is the free end of the inner cable 20a, moves back and forth by that amount. Therefore, the spline inner cylinder 27 rotates together with the shift arm 37 in the direction of arrow K (see Fig. 5), and as a result, the operating cylinder 28 rotates together with the operating arm 41 and the second operating arm 42 in the direction of arrow E (see Fig. 4). Turn shift lever 4
rotates in the direction of arrow J (see Figure 5). In this case, since the support cylinder 24a is arranged on the rotation center of the shift lever 4, the rotation center of the spline inner cylinder 27 and the operation cylinder 28, and therefore the operation arm 4
1. The rotation center of the second operating arm 42 and the rotation center of the shift lever 4 in the shift direction match, and the operating force of the operating arm 41 and the second operating arm 42 is smoothly transmitted to the shift lever 4 without loss. . Also, one end side of the shift cable 20 is connected to the coupler female body 3.
9 and the coupler male body 39a, and the inner cable 20a is rotatably supported by the link ball 3.
Since the inner cable 20a is connected to the shift arm 37 at 8, the forward and backward movement of the inner cable 20a is controlled by the shift arm 3.
It is smoothly converted into a rotation of 7. Furthermore, since the second operating arm 42 and the shift lever 4 are connected via the spherical bearing 44, power is transmitted smoothly from the second operating arm 42 to the shift lever 4 in both the select direction and the shift direction. . Further, by using the couplers 29 and 31, the select cable 16 will not be twisted even if the operation tube 28 is rotated.

FIG. 9 shows another embodiment of the device of this embodiment.

According to the present invention, as embodied in the above embodiments, an operating mechanism part, in which the operating arm is rotatable around its axis and protrudes so as to be movable back and forth in the axial direction, is erected on the mounting plate, This mounting plate is mounted on the steering wheel by aligning the axis of the operating mechanism with the axis of the shift lever protruding from the steering column, connecting the shift lever and the operating arm, and attaching the mounting plate to the steering wheel. By connecting the end of the attached shift cable to the operating mechanism and fitting the select cable into the operating mechanism in the axial direction, a useful column-type operating device can be obtained for the first time; Focusing on the fact that there is enough space for the driver above the steering wheel and there are no obstacles, we placed a mounting plate on the steering wheel and fixed it, and even if the operating mechanism was set up from this mounting plate, there would still be enough space. In addition, since it is lightweight, it is extremely easy to attach and detach the operating device as a whole, and it is also extremely easy to attach and detach the shift cable and select cable to the operating mechanism section since there is nothing nearby. This is further achieved by making it possible to attach and detach the select cable in the axial direction in response to reciprocating movement by the operating mechanism, and the shift cable in the longitudinal direction of the mounting plate in response to rotation by the operating mechanism. It does not require a complicated structure and is easy to install and remove. Therefore, one type of device can be used regardless of the type of car, and there is no need to remove the passenger seat as in the past. In addition, all you need to do is place the mounting plate on the steering wheel and align the axis of the operating mechanism and the center of rotation of the shift lever. No need to adjust. This is based on the fact that the shift or select of the operating arm and the shift or select of the shift lever make exactly the same movement. Furthermore, by aligning the axis of the operating mechanism and the center of rotation of the shift lever, the movement of the shift lever and the movement of the operating arm are the same, resulting in high transmission efficiency and extremely smooth operation. can be done. In addition, a device with predetermined parts is attached to the steering wheel, and the size and length of the steering wheel and shift lever are ergonomically constant, so it does not matter what type of car it is, even if it is a bench seat type. Moreover, it is extremely versatile regardless of the size of the engine space.
