Abstract

In order to solve the technical problems of the prior art such as long shift idle stroke and secondary impact, the present invention provides a synchronizer and a transmission, including a synchronizer gear sleeve, a synchronizer gear hub, a synchronizer ring and coupling teeth. The ring includes a ring-shaped body, the outer ring surface of the ring-shaped body is provided with a locking boss, the outer peripheral surface of the synchronizer hub is provided with an axially penetrating relief groove, and the locking boss The table can be axially displaced in the said relief groove; one end of the locking boss near the side of the synchronizer hub is provided with two first locking surfaces forming an angle, and the synchronizer teeth The inner peripheral surface of the sleeve is provided with a pair of locking teeth for locking the locking boss, and two second locking teeth corresponding to the two first locking surfaces are provided on the end surface of the locking pair of teeth. stop surface. The synchronizer of the present invention is beneficial to cost control, and at the same time reduces the axial layout space of the synchronizer, reduces the secondary impact of shifting and shifting noise, and is beneficial to the compactness of the overall layout structure of the transmission.

Description

technical field [0001] The invention belongs to the field of transmissions, in particular to a synchronizer of a transmission. Background technique [0002] Automobile synchronizer is an important component in automobile transmission, which plays a very important role in achieving smooth, light, fast, no impact, no noise and prolonging the life of gears in the process of shifting gears. [0003] At present, the commonly used inertia synchronizer includes gear sleeve, gear hub, synchronous ring and coupling teeth. When shifting gears, the gear sleeve pushes the synchronous ring to approach the coupling teeth. The synchronous ring and coupling teeth are frictionally fitted to make the coupling teeth complete synchronous rotation. Then, the gear sleeve can smoothly enter the coupling gear to transmit power and complete the gear shifting action. [0004] In the existing synchronizer, the synchronizing ring includes an annular base body, the base body is provided with an inner t...
