Automotive knowledge gearbox synchronizer

Inside the structure of the manual gearbox there is a very important device that is the "synchronizer". The role of the synchronizer is very obvious, that is, when the gear is shifted, the speed of the gear on the power output side is faster than that of the gear that will soon be switched into this gear. If there is no synchronizer, a slowly rotating gear is forced into a high speed. In the rotating gear, teething will definitely occur.

More advanced tri-cone synchronizer

Synchronously speaking, it is said that the friction plate is arranged on the combination sleeve and the gear set. Unlike the general friction plate, the friction surface is conical. The role of this group of friction plates is to advance the friction between the straight teeth and the set teeth of the disk beforehand, so as to transfer the energy of the larger rotational speed to the lower rotational speed side, so that the rotational speed of the smaller rotational speed side increases the rotational speed. It is synchronized with the rotation speed of the larger speed. This can not only ensure normal shifting, but also play a buffering role, and the number and material of the cone friction plate group directly affects the performance of the synchronizer.
