Abstract

The invention discloses a reverse-gear synchronizer assembly used in a manual transmission. The reverse-gear synchronizer assembly comprises an input shaft, hubs, gear sleeves and reverse-gear gear sets. Each gear sleeve is located between a corresponding bearing and the corresponding reverse-gear gear set, a fixing taper ring is further arranged between each bearing and the corresponding gear sleeve, and each gear sleeve is further provided with a first synchronous ring. Each reverse-gear gear set is further provided with a synchronous gear ring, wherein one end of the synchronous gear ring is connected with the reverse-gear gear set in an engaged manner, and the other end of the synchronous gear ring extends towards the corresponding gear sleeve side. Each gear sleeve is further provided with a second synchronous ring used for being matched with the corresponding synchronous gear ring, the second inner ring face of each second synchronous ring is in a conical shape, and each second inner ring face can be kept to be tightly matched with the outer ring face of the corresponding gear ring. The reverse-gear synchronizer assembly is simple in structure and convenient to install, the input shaft can be effectively decelerated so as to achieve synchronous input shaft deceleration, a reverse gear can be better engaged, and reverse-gear tooth collisions are avoided.

Description

technical field [0001] The invention relates to the technical field of automobile reverse gear parts assembly, in particular to a reverse gear synchronizer assembly. Background technique [0002] The manual gearbox is mainly composed of a gear shaft transmission system, a synchronization system, a gear selection mechanism, and a housing structure. , to achieve smooth gearing, but also to ensure that the synchronous system maintains stable torque transmission during gearing, and no jumping gears occur. The principle of the ordinary reverse gear synchronizer is to synchronize the speed of the gear sleeve and the reverse gear through the friction of the conical surface in contact between the gear ring and the combined teeth, so as to achieve smooth shifting; ordinary manual transmissions do not have reverse gear semi-synchronization / With the fully synchronous function, when the vehicle speed is not 0, the phenomenon of reverse gear kicking often occurs, causing complaints fro...
