Problems solved by technology

But, because in the synchronization process of the synchronizer system of the prior art mentioned above, when the friction pair of the synchronous ring 40 and the ring gear 50 exists in the situation that the dialing ring stage and the free travel stage are not released, like this, if the meshing stage starts It may cause a secondary impact on the gear shift, causing the gear shift force to appear a secondary peak during the entire gear shift process, resulting in insufficient shift comfort

Abstract

The invention relates to the field of synchronizers, in particular to an axial elastic component for a synchronizer system and a synchronizer system. The axial elastic component for a synchronizer system according to the present invention includes: a thrust bearing; and an elastic portion, which is disposed on one of the outer ring or the inner ring of the thrust bearing and extends away from the thrust bearing. When the elastic portion is elastically deformed, the elastic portion can generate an axial elastic force. In addition, the invention also provides a synchronizer system using the axial elastic component. In this way, the synchronous system according to the present invention facilitates the disengagement of the synchronous ring from the ring gear by providing additional axial force, thereby reducing the probability of secondary impact of the shifting force during the entire shifting process and improving shifting comfort.

Description

technical field [0001] The invention relates to the field of synchronizers, in particular to an axial elastic component for a synchronizer system and a synchronizer system using the axial elastic component. Background technique [0002] The synchronizer is one of the key components in the transmission, especially the automobile transmission, and the performance of the synchronizer directly determines the shifting performance of the transmission. [0003] figure 1 A schematic cross-sectional view of a prior art synchronizer system (lock ring inertial synchronizer system) is shown in . Such as figure 1 As shown, the synchronizer system includes a gear sleeve 10 , a gear hub 20 , a synchronizer slider 30 , a synchronizer ring 40 and a ring gear 50 . The gear sleeve 10 is coupled to the gear hub 20 from the outer side in the radial direction R and can slide in the axial direction A due to the action of a shift fork (not shown). Spline connection is adopted between gear hub 2...
