Description

Technical Field

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

[0002] There is a very important device inside the structure of the manual transmission, that is the "synchronizer". The role of the synchronizer is very obvious. That is, when shifting gears, the speed of the gear at the power output end is faster than the gear that is about to be shifted into this gear. If there is no synchronizer, forcing a slow-rotating gear into a high-speed rotating gear will definitely cause gear rattling.

[0003] The current synchronizer gear hub will cause gear hub fatigue after long-term use, and then the gear teeth will wear and break, and the entire gear hub needs to be replaced. Replacing the entire gear hub is very inconvenient, time-consuming and labor-intensive, making the replacement efficiency low. For this reason, we propose an automobile synchronizer that is easy to replace. Utility Model Content
