Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0015] like figure 1 , figure 2 As shown, the unilateral synchronizer includes a gear hub 1 and a slider 3 installed in the slider slot 5 of the gear hub 1. The gear hub 1 has a left end face 7, a right end face 2 and an inner arc surface 6. The slider A limit block 4 is clamped in the slot 5 to close one end of the slider slot 5, such as image 3 As shown, the limit block 4 is integrally formed of plastic, and is composed of a limit block 44 and two clamping feet 45 perpendicular to the limit block 44. The upper side 41 of the limit block 44 is an arc that matches the inner arc of the gear hub 1. The surface 6 is an arc surface with the same radian. The limit block 44 extends upward from the middle of the upper side surface 41 to form a stop block 42 . like Figure 4 , Figure 5 As shown, the two sides of the slider slot 5 are symmetrical two-stage ste...

Abstract

The present invention relates to unilateral synchronizers. It includes a gear hub and a slider installed in the slider slot of the gear hub. The gear hub has a left end face, a right end face and an inner arc surface. The slider slot is clamped with a limit block, and the limit block is made of plastic. forming, which closes one end of the slider slot. On the premise of ensuring the reliable position limit of the synchronizer slide block, the invention has the advantages of simple block position limit structure and low cost.

Description

technical field [0001] The present invention relates to synchronizers in transmissions, in particular to single-sided synchronizers. Background technique [0002] Synchronizer is an important execution component for gear switching in automobile transmission. One synchronizer has left and right sides, which can execute one gear respectively, and can execute two gears in total, while unilateral synchronizer only uses one side, only Responsible for executing a gear. The unilateral synchronizer is also widely used, including the gear hub and the slider installed in the gear hub slider slot. The gear hub has a left end face, a right end face and an inner arc surface. The limit reliability of the slider is poor, and there is a risk of the slider coming out. [0003] ZL2016202841364 discloses a unilateral synchronizer, comprising a gear hub, a gear sleeve sleeved on the gear hub, a slider slot is provided on the outer wall of the gear hub, a slider is connected in the slider slot...
