Problems solved by technology

[0002] At present, most of the gear selection devices used in China are equipped with a set of spring shift and limit mechanisms on the shift shafts on both sides of the shift lever, that is, two shift springs, two washers and two collars. To realize the position selection function in the process of shifting gears, this technical solution has many parts and complex structures, and the assembly process is cumbersome and time-consuming, resulting in a relatively high cost of the entire gear selection device

Embodiment Construction

[0016] The present invention will be further described below in conjunction with drawings and embodiments.

[0017] Such as figure 1 , figure 2 , Figure 5 , Image 6 with Figure 7 As shown, a gear selection device for an automobile transmission includes a shift box 2, a shift shaft 1 pierced in the shift box 2, a shift lever 3 and a limiter 4, wherein the shift shaft 1 The limit piece 4 is set on the top, and the limit piece 4 is in the shape of a U-shaped opening. There is a bar-shaped hole in the middle of the top end of the limit piece 4. The limit piece 4 passes through the first positioning member 21 in the shift box 2. The axial displacement is limited by the third positioning member 23, the third positioning member 23 is located on the left side of the limiter 4, the first positioning member 21 is located on the right side of the limiter 4, and the shift shaft 1 in the limiter 4 The shift lever 3 is fixed on the top, and the shift lever 3 can rotate circumferent...

Abstract

The invention discloses a gear selecting device of an automobile gearbox. The gear selecting device comprises a gear shifting box, a gear shifting shaft penetrating the gear shifting box, a gear shifting rocker and a limiting part, wherein the limiting part is sleeved on the gear shifting shaft and is limited by a first locating component and a third locating component inside the gear shifting box to perform axial displacement, the gear shifting rocker is fixed on the gear shifting shaft inside the limiting part and can rotate in the circumferential direction inside the limiting part and perform axial displacement via the limiting part, and a spring extension mechanism is arranged on the gear shifting shaft on one side of the limiting part. A limiting function in gear selection of the gearbox is realized with one spring extension mechanism only, the gear selecting device is simple in structure, low in cost and convenient to assemble, and large mounting space is saved.

Description

technical field [0001] The invention relates to a vehicle transmission control mechanism, in particular to an automobile transmission gear selection device. Background technique [0002] At present, most of the gear selection devices used in China are equipped with a set of spring shift and limit mechanisms on the shift shafts on both sides of the shift lever, that is, two shift springs, two washers and two collars. To realize the position selection function in the gear shifting process, this technical solution has many parts and components, the structure is relatively complicated, the assembly process is cumbersome and time-consuming, resulting in a relatively high cost of the entire gear selection device. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a gear selection device of an automobile transmission using a unilateral spring shift and limit mechanism. The gear selection device has a simple structure and s...
