Problems solved by technology

[0004] The above-mentioned patent uses the interlock plate to control the shift finger on the selector shaft to only drive one shift fork to rotate, which can solve the problem of shift sticking, but the structure is relatively complicated, and it operates the selector arm when shifting to drive the selector. The gear shaft and the interlock plate move to complete the gear selection, so that a space larger than the shift stroke must be reserved at both ends of the gear selection shaft on the transmission case, which increases the axial size of the transmission, and the structure is complex and takes up Large space, not suitable for light subcompact car

Embodiment Construction

[0024] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0025] Such as Figures 1 to 3 As shown, a transmission shift mechanism includes a shift shaft 1 fixedly connected to the transmission case and three shift forks 2 that are vacantly sleeved on the shift shaft 1. There is also a cylindrical fork 2 in the transmission case. The wheel hub 3 is fixedly connected with a driven gear 5 at the lower end of the wheel hub 3, and the driven gear 5 is coaxially arranged with the wheel hub 3. There are three curved guide rails 4 on the outer side of the hub 3 respectively corresponding to the fork positions. The guide rails 4 are three grooves 41 located on the outer side of the hub 3 . The floating size of the guide rails 4 is equal to the shift stroke. A connecting pin 6 is arranged...

Abstract

The invention provides a gear shifting mechanism of a transmission, which belongs to the technical field of automobiles. It solves the problem that the existing transmission shifting mechanism has a complex structure and occupies a large space, and is not suitable for light and small cars. The transmission shift mechanism includes a shift shaft fixedly connected to the transmission case and a shift fork sleeved on the shift shaft. The transmission case also has a cylindrical hub connected to the power input end. The outer side has guide rails with the same number and corresponding positions as the forks, and a part of the forks is connected with the guide rails. The shifting mechanism of the transmission has the advantages of simpler and more compact structure and better shifting effect.

Description

technical field [0001] The invention belongs to the technical field of automobiles, relates to an automobile transmission, in particular to a transmission shift mechanism. Background technique [0002] The automobile transmission must be equipped with a shifting mechanism to realize the shifting work of the transmission. The traditional shifting mechanism uses the shift finger to toggle the fork frame on the shift fork assembly to achieve the purpose of shifting. This structure requires multiple shifting The gear shift fork assembly, and because the shift fork shaft assembly is integrated, the shift finger drives the shift fork to move axially when shifting gears, which will cause shift sticking. [0003] In view of existing problems, people have designed various shifting mechanisms, and some have also applied for patents. For example, Chinese patent literature discloses a transmission shifting mechanism [200810241299.4; publication number: CN101457832A], which includes a ge...
