Abstract

In order to solve the technical problems of longer gear shifting idle stroke, second impact and the like in the prior art, the invention provides a synchronizer and a speed changer. The synchronizer comprises a synchronizer gear sleeve, a synchronizer gear hub, synchronizing rings and combining gears, wherein each synchronizing ring comprises a circular ring body; a locking lug boss is arranged on the outer ring surface of each circular ring body; an axially communicated position avoiding groove is formed in the outer peripheral surface of the synchronizer gear hub; the locking lug boss can move in the axial direction in the corresponding position avoiding groove; one end of the locking lug boss near one side of the synchronizer gear hub is provided with two first locking surfaces; an included angle is formed between the first locking surfaces; the inner peripheral surface of the synchronizer gear sleeve is provided with locking opposite teeth used for locking the locking lug boss; and two second locking surfaces corresponding to the two first locking surfaces are arranged on the end surfaces of the locking opposite teeth. The synchronizer is favorable for cost control; meanwhile, the axial arrangement space of the synchronizer is reduced; the gear shifting secondary impact and the gear shifting noise are reduced; and the scheme is favorable for integral arrangement structure compactness of the speed changer.

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...
