Double-conical-surface automobile synchronizer

Abstract

The invention discloses a double-conical-surface automobile synchronizer, relates to the technical field of automobile parts, and provides the following scheme aiming at the problems that an existing double-conical-surface automobile synchronizer is large in mass, heavy during adjustment, high in production cost and poor in use effect, consumes more materials in the production process, does not utilize the design of light weight of a whole automobile and is high in production cost. Comprising a splined hub, arc-shaped grooves are formed in the two sides of the splined hub in an opening and closing mode, through holes are formed in the inner walls of the arc-shaped grooves, a plurality of conical surface inner teeth arranged at equal intervals are fixedly welded to the inner walls of the through holes, and a plurality of conical surface outer teeth arranged at equal intervals are fixedly welded to the outer side of the splined hub; the automobile synchronizer is reasonable in design and convenient to adjust and use, the synchronizer is small in mass and high in strength, the light weight design of the whole automobile is utilized, materials can be saved in the production process, the production cost is reduced, the use effect is good, and the automobile synchronizer is worthy of being used and popularized.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to a double-cone surface automobile synchronizer. Background technique [0002] The synchronizer is a very important device in the automobile gearbox. Its function is to solve the problem of the engine speed and speed change during the shifting operation of the car because the gear speed of the power output end is faster than the gear that is about to be shifted into this gear. The mechanical device with inconsistent speed of the box can effectively avoid the inability to shift gear, eliminate the gear noise when shifting, etc. If there is no synchronizer, a slow rotating gear is forcibly inserted into a high-speed rotating gear. The phenomenon of tooth beating; the synchronizer is actually the friction plate arranged on the combination sleeve and the gear set. Different from the general friction plate, its friction surface is conical. The function of this group of friction...
