Efficient conical surface automobile synchronizer for new energy automobile

Abstract

The invention relates to the technical field of automobile synchronizers, in particular to an efficient conical surface automobile synchronizer for a new energy automobile. The synchronizer comprises a locking ring and an inner ring for gear engagement, wherein the locking ring comprises an annular ring and a combined gear ring, and a plurality of groups of clamping grooves are formed in the inner side wall of the circumference of the annular ring at equal angles; the clamping grooves extend to the inner side wall of the circumference of the combination gear ring and penetrate through the inner side wall of the circumference of the combination gear ring, second conical blocks are arranged on the inner side wall of the circumference of the combination gear ring and between every two adjacent clamping grooves, the inner conical side wall of each second conical block is arranged to be a second conical wall, the second conical walls are matched with the first conical walls, and the inner ring is mounted in the locking ring. The inner ring capable of translating relative to the lock ring is additionally arranged in the lock ring, so that two groups of friction acting surfaces are formed among the lock ring, the inner ring and the circular truncated cone part, and under the action of an elastic piece, when a joint sleeve is pulled back, one group of friction acting surfaces are quickly reduced, so that the lock ring is effectively prevented from being locked on the circular truncated cone part, so that the lock ring is conveniently and easily pulled to be right; and locking and impact in gear shifting are avoided.

Description

technical field [0001] The invention relates to the technical field of automobile synchronizers, in particular to a high-efficiency tapered automobile synchronizer for new energy automobiles. Background technique [0002] In order to reduce the noise of automotive transmissions and the power consumption per 100 kilometers of new energy vehicles, eliminate shifting shocks, prolong the life of gears and transmission systems, and achieve smooth and rapid shifting, synchronizers are commonly used in automotive transmissions. The synchronizers currently on the market generally belong to the lock ring type inertial synchronizer. This type of synchronizer cleverly uses the principle of friction mechanics to ensure that the synchronous gear sleeve and the gear gear to be combined cannot be in contact with each other before synchronization is achieved. In order to avoid the generation of shifting impact and noise, after contacting at the same time, the synchronous gear sleeve is sync...

Problems solved by technology

[0004] However, at present, the form of bonding carbon and paper friction materials is often used to increase the synchronous capacity. This structure is prone to locking between the synchronous rings or between the synchronous ring and the gear cone surface, resulting in shifting.
