Description

Technical Field

[0001] The utility model relates to the technical field of automobile synchronizers, in particular to an automobile synchronizer which is convenient for rapid maintenance. Background Art

[0002] The automobile synchronizer refers to an important component used in the automobile transmission system, which is mainly used to achieve synchronization between different gears and smooth transition of gear shifting. In the automobile transmission, the synchronizer is located between each gear and the shaft. Its function is to enable the gears to mesh smoothly during gear shifting to avoid collision and wear, thereby achieving smooth gear shifting operation. During the use of existing automobile synchronizers, since the annular gear portion and the gear hub are usually an integrated structure, the annular gear portion and the gear hub cannot be separated. If the annular gear portion or the gear hub in the automobile synchronizer is damaged, the annular gear portion or the gear hub cannot be replaced and repaired separately, and the automobile synchronizer needs to be replaced and repaired as a whole, which increases the later maintenance cost of the automobile synchronizer. Therefore, we propose an automobile synchronizer that is easy to quickly repair, so as to solve the above problems. Utility Model Content
