Abstract

The invention discloses a synchronizer inner ring conical surface friction material bonding mold and bonding method thereof. The bonding mold is mainly formed by an upper mold, a lower mold and a heating mechanism, wherein the upper mold is provided with a discharging assembly and a floating assembly, and the lower mold is provided with a material butting assembly. Through the bonding mold, not only can pressurized heating bonding of a synchronizer inner ring conical surface subjected to prebonding of friction materials be achieved, but also automatic discharging and automatic material butting after bonding is finished can be achieved, uniformity of the heating effect is guaranteed, bonding efficiency is improved, adhesion influences of contact parts between an inner ring and the upper mold and between the inner ring and the lower mold are avoided, and bonding quality and production efficiency are improved.

Description

technical field

[0001] The invention belongs to the technical field of vehicle gear transmission, and designs a processing mold for a vehicle synchronizer material, in particular to a bonding mold and a bonding method for an inner ring cone friction material of an automobile synchronizer. Background technique

[0002] The automobile synchronizer is a very important device inside the manual transmission. The transmission includes an input shaft and an output shaft. The function of the synchronizer is to make the gear speed difference between two adjacent gears smaller when shifting, making the shift more smooth. Automobile synchronizers include atmospheric pressure type and inertial type. At present, inertial synchronizers are the main ones.

[0003] The characteristic of the inertial synchronizer is that it relies on friction to achieve synchronization. Therefore, the friction material of the automotive synchronizer ring plays a vital role in the synchronization process of ...
