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 provided has a shift pattern as shown in Figure 8. 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 control 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. A pair of left and right pistons that are movably supported but can also slide freely in the axial direction within the inner shaft. and each piston located between these pistons at its inner shaft end A return force that biases the rod part protruding from the lever bracket so that it comes into contact with the lever bracket. In addition to housing the puller, it is neutral between the upshift range and downshift range. Positioning mechanism in select direction including holding position, shift up range and shift lever Provides a positioning mechanism in the shift direction that functions outside the stroke range between unranges. It is characterized by a large number of characters.

[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 operated in the stroke range between the upshift range and the downshift range. Since the positioning mechanism in the foot direction does not work, the neutral retarder inside the inner shaft The shift up range and downshift range are controlled by the operational reaction force that deflects the spring spring. automatically returns to the intermediate position of the lever (neutral holding position of the lever). In addition, the operation lever Shift up range and shift down range according to the select shift operation of Since the positioning mechanism operates at lever positions other than It will be held even if you release your hand at the position.

Position, A is the auto drive range formed in the select direction, R is the auto drive range formed in the shift direction. The reverse range achieved, N indicates the neutral set position.

[0008] The operating lever 11 is installed inside the guide box 10 via the lever bracket 14. Can be attached. The middle part of the lever 11 is freely rotatable around the outer circumference of the hollow inner shaft 15. It is supported via a sleeve so as to be tiltable in the selection direction using the inner shaft 15 as a fulcrum. It will be done. In addition, the lower end of the leg-shaped lower lever portion 17 of the lever 11 can be moved in the selection direction. The lever 11 is engaged with a select guide 18 that allows the lever 11 to shift with the lower end of the lever 11 as a fulcrum. It is possible to tilt in the direction.

[0009] Inside the inner shaft 15 are a pair of left and right pistons 19 that can freely slide in the axial direction. A return spring 20 is located between them and urges the piston 19 outward. The pistons 19 on both sides face the shift direction of the lever bracket 14. A rod portion 19A that elastically supports the lever 11 is formed on the side surface.

0010 An inner shaft 15 is provided on the side surface of the lever bracket 14 facing the selection direction. A guide hole 21 is formed to guide the movement of the A free guide shaft 22 is provided projecting from the inner shaft 15. Furthermore, lever 11 The sleeve 16 and the lower lever part 17 have these functions associated with the selection operation of the lever 11. Elongated holes 23 and 24 are respectively formed to allow movement relative to the guide shaft 22. It will be done.
