Asymmetric soldered tooth synchronizer of automobile

The invention relates to the technical field, particularly discloses an improved asymmetric soldered tooth synchronizer for a mechanical automatic transmission and a manual transmission for the traditional automobile, and aims to overcome the technical problem that the shift secondary peak value in a clamping ring sliding block synchronizer technology is large. The asymmetric soldered tooth synchronizer of the automobile provided by the invention comprises a clamping ring, a soldered tooth ring, a tooth sleeve, a tooth sleeve and a sliding block group, wherein soldered teeth of the clamping ring are of symmetrical structures; the tooth sleeve comprises tooth sleeve symmetrical soldered teeth and tooth sleeve asymmetric soldered teeth, the soldered tooth ring is provided with tooth ring asymmetric soldered teeth, and the tooth ring asymmetric soldered teeth correspond to the tooth sleeve asymmetric soldered teeth. The improved asymmetric soldered tooth synchronizer provided by the invention has the advantages that the improved secondary peak value which is generated in shift is obviously reduced, and the harshness and comfort property of the shift of the synchronizer are improved.
