Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to an improvement of a shift change operating lever device for an automatic transmission vehicle.

0002

[Conventional technology]

Various types of automatic transmission systems have been proposed for vehicles, but none of them have been installed in the driver's cab. The shift change operation lever device to be installed has a shift pattern as shown in Figure 7. It is equipped with a guide groove to guide the select shift operation of lever 2. . (Refer to Utility Model Application No. 59-70610).

0003

[Problem that the idea aims to solve]

However, in such a conventional example, when changing gears, the operating lever 2 must be pressed once. Return to neutral position, select as necessary, then shift. In situations where frequent gear shifting operations are required, operating the levers becomes cumbersome. There was also the problem that misshift operations were likely to occur.

0004 Therefore, this idea was developed to solve these problems by introducing a shift upshift driver. Shift change operation that allows continuous down operation with one-way lever operation The purpose is to provide a lever device.

[0005]

[Means to solve the problem]

Therefore, this idea is based on the shift pattern that guides the select shift operation of the operating lever. A shift up range and a shift down range are provided in the same select row of the shift guide groove. The operating lever is a hollow inner shaft located in the middle of the lever inside the lever bracket. Tilt in the select direction using the foot as a fulcrum, and in the shift direction using the bottom end of the lever as a fulcrum. While it is movably supported, the lever is attached to the inner shaft side which is fixed at both ends to the lever bracket. A guide hole is formed to guide the movement of the bar in the select direction and shift direction. A guide shaft that can freely slide in the guide hole is installed protruding toward the lever side, and an inner shaft is installed in the guide hole. A pair of left and right pistons that can freely slide in the axial direction on both sides of the guide shaft inside the The same one biases the guide shaft to the neutral position through each of the pistons. While storing a pair of return springs, the lower end of the lever and its selection direction are The shift up range and shift down range are located between the select guide groove that guides the movement. The positioning mechanism in the select direction, including the neutral holding position between the levers, is also and the outer circumference of the inner shaft for the shift up range and down shift range. The present invention is characterized by providing a position mechanism in the shift direction that functions outside the rotation range.

[0006]

[Effect]

Shifting up and downshifting operations are performed by selectively moving the operating lever to these range positions. This can be done by shifting, one gear at a time for each shift, for example, a 2nd gear shift. When trying to raise the gear, it is enough to repeat the shift operation twice. In that case, The operating lever can be shifted within the stroke range of upshift range and downshift range. Since the positioning mechanism in the direction of The shift up range and downshift range are changed by the operational reaction force that deflects the spring. automatically returns to the intermediate position of the lever (neutral holding position). In addition, the operation lever With the select shift operation, the shift up range and shift down range and beyond Since the positioning mechanism operates at the outer lever position, the lever is moved to the desired select shift. Even if you release your hand at this position, it will be held.

A guide hole (not shown) is formed to guide movement in the select direction and shift direction. Ru. In the guide hole, there is a guide shaft that can freely slide in two directions for select shift. The foot 22 is passed through and both ends thereof are connected to the lower lever portion 17. inner shaft 15 includes a pair of left and right pistons 1 that can freely slide in the axial direction at both ends of the guide shaft 22. 9 and the guide shaft 22 to the neutral position via each of these pistons 19. A pair of return springs 20 are also housed therein. In addition, lower lever There is a lever in the shift direction between the outer part 17 and the sleeve 16 on the outer periphery of the inner shaft 15. A gap 21 is provided to allow the bar 11 to tilt.

0010 The lock ball 23 housed in the elongated hole of the sleeve 16 is slidably inserted into the lower lever portion 17. A spring 25 is applied to the outside of the inner shaft 15 via a flexible piston-shaped spring receiver 24. A positioning mechanism 27 that biases the circumference is provided, and a lever 1 is provided on the outer circumference of the inner shaft 15. The recess 28 where the lock ball 23 engages in the reverse range R position of 1 and the lever 1 1 intermediate position between shift up range U and shift down range D (neutral holding position H ), a recess 29 into which the lock ball 23 engages is also formed. Also the lower lever Similarly, the lower end of the portion 17 is also provided with a positioning device consisting of a piston pin 31, a spring 32, etc. A mechanism 33 is provided to the select guide 18 attached to the lever bracket 14. Neutral set position N, neutral holding position H, auto range position A of lever 11 Recesses 34 to 36 with which the spherical end of the piston pin 31 engages are formed in each of the recesses 34 to 36. It will be done.

[0011] 40 is provided internally as shown in FIG. 5 in order to detect the select shift position of the lever 11. A plurality of switches 41 to 48 are arranged corresponding to the shift pattern of the lever 11. In the switch box, these switches 41 to 48 are integrated with the sleeve 16.

From ON, lever 1 is determined to have entered shift down range D. 1 select shift position is detected.

0012 With this configuration, upshifting and downshifting operations can be performed by using the operating lever 11. This can be done by selectively shifting (tilting) to these range positions, and can be done in one cycle. Regarding shift operation, when trying to shift up one gear at a time, for example, 2nd gear, the shift All you have to do is repeat this action twice. In that case, the operating lever 11 is in the shift up range. The positioning mechanism 27 in the shift direction is in the stroke range of U and shift down range D. Since it does not work, the operation reaction that bends the return spring 20 inside the inner shaft 15 is Depending on the force, the intermediate position between upshift range U and downshift range D (maintaining neutral) Automatically returns to position H). In addition, with the select shift operation of the operating lever 11, means the lever position is below shift up range U and shift down range D. Auto drive range A, neutral holding position H, neutral set position N and Since the positioning mechanism 33 or 27 operates in the reverse range R, the lever 11 is Even if you release your hand at that shift select position, it will be held.

[0013] Therefore, shifting up and down operations are performed continuously using a lever in one direction. This allows you to perform quick shift changes according to the situation, and prevents misshift operations. The frequency of production will also be much less. In addition, the overall configuration of the device is relatively simple, and costs are low. But it will be advantageous.
