Embodiment 1

[0060] Such as Figure 1 to Figure 5 As shown, a shift mechanism 100 provided by an embodiment of the present invention includes a housing 110 and a first shift fork 120 . Wherein, the casing 110 can be understood as a part of the casing assembly of the transmission, and the casing 110 can be in any shape according to actual requirements. Usually, the shift fork is connected with the housing 110 , and the shift fork moves in the horizontal direction to move the synchronizer; or, the shift fork rotates around a fixed rotation fulcrum to move the synchronizer.

[0061] Further, the first shift fork 120 includes a first connecting portion 121 , a first shifting portion 123 and two first fork legs 122 . Specifically, one end of the first connecting portion 121 is connected to a first fork 122, and the other end of the first connecting portion 121 is connected to another first fork 122, and a first connecting portion 121 and two first forks are connected to each other. The feet 1...

Embodiment 2

[0069] Such as Figure 1 to Figure 3 As shown, the shift mechanism 100 further includes a first pulling portion 131 connected to the first connecting portion 121 of the first shift fork 120 . Specifically, the first pulling part 131 is rotationally connected to the first connecting part 121 of the first shift fork 120 through the shifter, and the first pulling part 131 can slide relative to the housing 110, where the sliding can is any direction. Furthermore, during the sliding process, the first driving part 131 can drive the first shift fork 120 to rotate around the centerline of the first connecting member 124 . The first connecting member 124 can be understood as a fixed rotational fulcrum of the first shift fork 120. By setting the first driving part 131, the first shift fork 120 is driven to rotate, and then the first driving part 123 can push the synchronizer to move. Realize shift operation.

[0070] It should be noted that the first pulling part 131 may be a pull r...

Embodiment 3

[0072] Such as figure 1 , figure 2 , image 3 , Figure 4 with Figure 7 As shown, the shift mechanism 100 further includes a mounting seat 133 , a second pulling portion 134 , a third pulling portion 135 and a fork shaft 136 . Specifically, the mounting seat 133 can slide relative to the housing 110 , and the second pulling portion 134 , the third pulling portion 135 and the fork shaft 136 are all passed through the mounting seat 133 . The mounting base 133 is provided with a chute 1331, the chute 1331 is a through groove structure, the first pulling part 131, the second pulling part 134 and the third pulling part 135 are all pierced in the chute 1331 of the mounting base 133, the second The pulling part 134 is in contact with the first driving part 131 , and the third driving part 135 is in contact with the second driving part 134 . The three driving parts can slide relative to the mounting seat 133 , and the sliding directions of the three driving parts are the same. ...

Abstract

The embodiment of the invention provides a gear shifting mechanism and a vehicle. The gear shifting mechanism comprises a shell and a first gear shifting fork, wherein the first gear shifting fork comprises a first connecting component, two first fork feet and first pushing components; the two first fork feet are connected with the first connecting component; through the first connecting component, the two first fork feet are connected with the shell; and the first pushing components are arranged on the first fork feet and used for pushing a synchronizer to move, so that the gear shifting operation can be achieved. In the gear shifting mechanism, the distance between the first connecting component and the first pushing components is regarded as a resisting arm; the distance between the first connecting component and first connectors is regarded as a power arm; according to the lever balance principle, the distance between the first pushing components and the first connecting component is less than the distance between the first connectors and the first connecting component, that is, the power arm is greater than the resisting arm, so that the synchronizer can be pushed by using relatively small gear shifting force and more labor can be saved; and furthermore, the possibility of obvious deformation and even damage caused by low self-strength can be reduced, the gear shifting can be easier, and the whole gear shifting process can be more stable and smoother.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicles, and in particular, relate to a shift mechanism and a vehicle. Background technique [0002] In the related art, the shift fork is U-shaped, and the fork shaft can drive the shift fork to rotate, and then the shift fork pushes the synchronizer to move to realize the shift operation. However, when the synchronizer is pushed by the fork pin of the shift fork, the fork pin is easily deformed, and a large force is required to make the synchronizer move. Contents of the invention [0003] In order to solve at least one of the above technical problems, an object of the embodiments of the present invention is to provide a shifting mechanism. [0004] Another object of the embodiments of the present invention is to provide a vehicle having the above-mentioned shifting mechanism. [0005] In order to achieve the above object, the embodiment of the first aspect of the present inve...
