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] The automobile synchronizer is a friction plate arranged on the coupling sleeve and the gear set. The function of this group of friction plates is to rub in advance before the spur teeth and the vertical teeth of the disc come into contact, so as to transfer the energy of the side with a higher speed to the side with a lower speed, so that the side with a lower speed can increase its speed and achieve synchronization with the side with a higher speed. This can not only ensure normal gear shifting, but also play a buffering role. The existing automobile synchronizer is usually an integrated structure. If it is damaged, the damaged area of ​​the automobile synchronizer cannot be replaced separately, and the entire automobile synchronizer needs to be replaced, resulting in a high maintenance cost of the automobile synchronizer.
