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 middle 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 die and method for bonding a friction material for a conical surface of an intermediate ring of a synchronizer. The bonding die is mainly composed of an upper die body, a lower die body and a heating mechanism, wherein the upper die body is provided with a floating assembly, and the lower die body is provided with a material ejection assembly. By means of the bonding die,pressurized and heated bonding of the conical surface, with the friction material attached in advance, of the intermediate ring of the synchronizer can be achieved, and automatic discharging and material ejection can be achieved after bonding is completed; uniformity of the heating effect is guaranteed; bonding efficiency is improved; the adhesion influence of the contact parts of the intermediate ring and the upper die body as well as the contact parts of the intermediate ring and the lower die body is 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 intermediate 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 synchron...
