Problems solved by technology

There are many disadvantages in this bonding process: long production cycle, high labor intensity of workers, high energy consumption in the production process, low production efficiency, and because the friction strip material is pre-loaded into the mold, the position of the friction material and the inner ring is not easy to control. It often occurs that the position of the friction material is deviated and the product is scrapped, and the bonding quality of the product is unstable

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 inertia synchronizer is characterized by relying on friction to achieve synchronization, so the friction material of the car synchronizer ring ring plays a vital role in the synchronization process of the car synchronizer! ...
