Synchronizer balking ring and method for manufacturing same

Abstract

The invention relates to a cone ring of a synchronizer and a manufacture method thereof. The cone ring of a synchronizer includes the basal body (1) of the cone ring and a friction material layer (3); wherein, the cone ring of a synchronizer also includes a metal plate layer (2); the metal plate layer (2) is jointed on the inner cone surface and / or the outer cone surface of the basal body (1) of the cone ring; the friction material layer (3) is a metal alloy. The cone ring of a synchronizer provided by the invention greatly reduces the manufacture cost; simultaneously the friction material layer can be jointed on the basal body of the cone ring through the metal plate layer by utilizing a simple manufacture technique, thereby manufacturing the cone ring of a synchronizer with low cost andgood synchronous effect. Besides, the cone ring of a synchronizer has the advantages of good wear resistance and long service life.

Description

technical field [0001] The present invention relates to a synchronizer used in a vehicle transmission, and more particularly, to a synchronizer cone ring and a manufacturing method thereof. Background technique [0002] The vehicle synchronizer is an important component in the vehicle transmission to make shifting light and silent, flexible and reliable, and to prolong the life of the mating gears. The cone ring of the synchronizer is the friction transmission element of the synchronizer, which generates friction torque with the conical surface of the matching gear, so that the relative speed of the active and passive parts approaches zero, so as to complete the synchronization in an instant, so that the main and passive parts The driven gears allow shock-free and silent gear changes. Generally, the greater the friction torque of the matching cone surface of the cone ring, the shorter the time required to complete synchronization and the more stable the synchronization perf...

AI Technical Summary

Problems solved by technology

However, since molybdenum is a scarce metal that is more expensive than copper, this technique has little practical effect on reducing the manufacturing cost of synchronizer cone rings

Moreover, since the spraying process is only applicable to pure metals, other friction materials other than metal molybdenum, such as metal alloys, cannot be bonded to the cone ring substrate by spraying, and the spraying process is more complicated and difficult to control
