Description

Technical Field

[0001] The utility model relates to the technical field of shift forks, in particular to an adjustable shift fork. Background Art

[0002] The transmission is an important component of the automobile power system. It outputs different torques and speeds through gear changes to meet the driver's driving speed requirements under different road conditions. The shift mechanism of common MT and AMT transmissions is mainly composed of a shift shaft, shift fork and shift block.

[0003] The function of a car's shift fork is to move the synchronizer sleeve to achieve the engagement and disengagement of each forward gear, thereby smoothing gear shifting. Currently, the shift fork is molded in one piece, and the fork length cannot be freely adjusted. It cannot adapt to different working conditions and must be customized, increasing costs. Utility Model Content

[0004] The purpose of the utility model is to provide an adjustable shift fork to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] An adjustable shift fork includes a shift shaft, an adjusting assembly is provided on the shift shaft, a shift fork is slidably connected to the adjusting assembly, the adjusting assembly includes an adjusting cylinder fixedly connected to the shift shaft, a shift fork is slidably connected to the adjusting cylinder, a first through groove is provided in the adjusting cylinder, a rotating ring is rotatably provided on the adjusting cylinder, a second through groove is provided on the rotating ring, a limiting rod is fixed on the shift fork, the limiting rod extends into the first through groove and the second through groove, and is slidably connected to the first through groove and the second through groove.

[0007] Furthermore, the first through-slot is opened along the axial direction of the adjusting cylinder, and the second through-slot is spirally arranged on the rotating ring.

[0008] Furthermore, it also includes a limiting ring, which is threadedly connected to the outer surface of the adjusting cylinder, and the rotating ring is rotatably arranged in a slot on the adjusting cylinder.

[0009] Furthermore, the shift fork includes a sliding rod slidably connected to the adjusting cylinder, the limiting rod is fixed on the sliding rod, and a fork ring is fixedly connected to the sliding rod.

[0010] Furthermore, a plurality of convex strips are fixedly provided on the slide bar, and each of the convex strips is slidably connected to a corresponding groove in the adjustment cylinder.

[0011] In the above technical solution, the adjustable shift fork provided by the utility model has the beneficial effect: through the provided adjustment component, when the length of the shift fork needs to be adjusted, the rotating ring is rotated, and the second through groove on the rotating ring causes the limit rod to move. Since the limit rod is also constrained by the first through groove, the limit rod moves along the first through groove, and the movement of the limit rod drives the shift fork to move, thereby adjusting the length of the shift fork to adapt to different working conditions.

[0012] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0021] See also Figure 1-3, an adjustable shift fork includes a shift shaft 1, an adjusting assembly 2 is provided on the shift shaft 1, a shift fork 3 is slidably connected in the adjusting assembly 2, the adjusting assembly 2 includes an adjusting cylinder 21 fixedly connected to the shift shaft 1, the shift fork 3 is slidably connected in the adjusting cylinder 21, a first through groove 22 is provided in the adjusting cylinder 21, a rotating ring 23 is also rotatably provided on the adjusting cylinder 21, a second through groove 24 is provided on the rotating ring 23, a limiting rod 32 is fixed on the shift fork 3, the limiting rod 32 extends into the first through groove 22 and the second through groove 24, and is slidably connected to the first through groove 22 and the second through groove 24.

[0022] By means of the provided adjustment assembly 2, when it is necessary to adjust the length of the shift fork 3, the rotating ring 23 is rotated, and the second through slot 24 on the rotating ring 23 causes the limit rod 32 to move. Since the limit rod 32 is also constrained by the first through slot 22, the limit rod 32 moves along the first through slot 22, and the movement of the limit rod 32 drives the shift fork 3 to move, thereby adjusting the length of the shift fork 3 to adapt to different working conditions.

[0023] Furthermore, the first through-slot 22 is formed along the axial direction of the adjusting cylinder 21, and the second through-slot 24 is spirally arranged on the rotating ring 23. The spirally arranged second through-slot 24 drives the limiting rod 32 to move along the first through-slot 22 in the axial direction, thereby adjusting the position of the shift fork 3.

[0024] Furthermore, a limiting ring 4 is included, which is threadedly connected to the outer surface of the adjustment cylinder 21, and the rotating ring 23 is rotatably arranged in the groove on the adjustment cylinder 21. By rotating the limiting ring 4, the limiting ring 4 abuts against one end of the rotating ring 23, and the other end of the rotating ring 23 is tightly abutted against the side wall of the groove, thereby fixing the rotating ring 23 and fixing the position of the adjusted fork 3.

[0025] Furthermore, the shift fork 3 includes a slide rod 31 slidably connected to the adjusting cylinder 21 , the limit rod 32 is fixed on the slide rod 31 , and a fork ring 33 is fixedly connected to the slide rod 31 .

[0026] Furthermore, a plurality of ridges 34 are fixedly provided on the slide bar 31, and each ridge 34 is slidably connected to a corresponding groove in the adjustment cylinder 21. The ridges 34 cooperate with the grooves to enhance the stability of the fork 3 sliding in the adjustment cylinder 21.

[0027] Working principle: When the length of the shift fork 3 needs to be adjusted, the rotating ring 23 is rotated, and the spirally arranged second through groove 24 on the rotating ring 23 causes the limit rod 32 to move. Since the limit rod 32 is also constrained by the axially arranged first through groove 22, the limit rod 32 moves along the first through groove 22. The movement of the limit rod 32 drives the shift fork 3 to move, thereby adjusting the length of the shift fork 3 to adapt to different working conditions.

[0028] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
