Problems solved by technology

[0003] It can be seen that the synchronizer device has only one friction layer, and the friction area is small, which limits the shift speed of the transmission. Therefore, it is necessary to provide a new synchronizer device to increase the shift speed

Abstract

The invention discloses an automobile synchronizer device which comprises a gear sleeve, a gear hub, a synchronization ring and a joint gear; the gear hub is sleeved with the gear sleeve; the joint gear is arranged at one end of the gear hub; a groove is formed in the joint gear; the synchronization ring is arranged in the groove; first contact surfaces are arranged between the synchronization ring and the joint gear; the number of the first contact surfaces is at least two; friction layers are arranged on the first contact surfaces; and the friction layers are pasted on the synchronization ring. According to the automobile synchronizer device, the multiple friction layers are arranged between the synchronization ring and the joint gear, so that the friction area is increased, and the gearshifting time is shortened.

Description

technical field [0001] The invention relates to a synchronizer device, in particular to an automobile synchronizer device. Background technique [0002] There is a very important device inside the structure of the manual transmission, that is the "synchronizer". The role of the synchronizer is very obvious. When shifting gears, since the gear speed at the power output end is faster than the gear that is about to be shifted into this gear, the mechanical device that solves the inconsistency between the engine speed and the gearbox speed during the shifting operation of the car can be used. Effectively avoid gear failure, eliminate gear noise when shifting gears, etc. If there is no synchronizer, if a slow-rotating gear is forced into a high-speed rotating gear, the phenomenon of tooth beating will definitely occur. With the continuous improvement of automobile emission requirements, the requirements for the working efficiency and weight of the transmission are also increased...
