Lock pin type automobile synchronizer

Abstract

The lock pin type automobile synchronizer comprises a joint sleeve, one side of the joint sleeve is connected with a first synchronous conical ring in a clamped mode, the other side of the joint sleeve is connected with a second synchronous conical ring in a clamped mode, the middle of the interior of the joint sleeve is connected with a shaft gear in a meshed mode, a tooth groove is formed in the inner side wall of the joint sleeve, and the shaft gear is connected with the joint sleeve in a meshed mode through the tooth groove. And positioning holes are formed in the surfaces of the first synchronous conical ring and the second synchronous conical ring. According to the lock pin type automobile synchronizer, relative sliding between the lock pin and the lock hole can be prevented, the locking effect of the lock pin is improved, the lock pin type automobile synchronizer can be more suitable for a positioning pin with the concave middle through the arc-shaped positioning plate, clamping is tighter, the positioning effect is better, the axial torque of the positioning pin is reduced, and the service life of the automobile synchronizer is prolonged. The clamping effect on the positioning pin is improved, the overall clamping effect of the clamping mechanism is enhanced through secondary abutting of the abutting spring and the abutting ball, the overall strength of the device is improved, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of synchronizers, in particular to a lock pin type automobile synchronizer. Background technique [0002] There is a very important device inside the structure of the manual transmission, that is the "synchronizer". The function of the synchronizer is very obvious, that is, when the gear is shifted, the speed of the gear at the power output end is faster than the gear that is about to be shifted into this gear, and the mechanical device that solves the inconsistency between the engine speed and the gearbox speed during the shifting operation of the car. , he can effectively avoid the inability to shift gears, eliminate the gear noise when shifting, etc. If there is no synchronizer, forcibly inserting a slow rotating gear into a high-speed rotating gear, the phenomenon of tooth knocking will definitely occur. [0003] The existing locking pin type automobile synchronizer cannot reduce the sliding between the...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a lock pin type automobile synchronizer, which solves the problem that the sliding between the lock pin and the lock hole cannot be reduced, thereby affecting the locking effect of the lock pin, and The clamping connection on the positioning pin generally uses a spring to abut against the ball, and the abutment effect is not good.
