Problems solved by technology

[0002] With the development of high-horsepower and high-torque manual transmissions, it has become extremely difficult for traditional synchronizers to achieve smaller transmission lengths through smaller installation distances and shift strokes, or to reduce the installation of synchronizers when the length of the transmission remains the same. It is also difficult to implement measures to increase the gear width and increase the bending fatigue and contact fatigue life of the gear.

Abstract

The invention aims to solve the technical problems of short service life of high-torque transmission gears and user requirements for lighter shifting, and provides an embedded compact high-performancesynchronizer and a transmission. An annular boss with a tapered inner wall is arranged on a gear assembly. An outer friction ring of the synchronizer is embedded in the annular boss, thereby reducingaxial installation distance of the synchronizer and increasing the tooth width of gears in the case that the total length of the transmission is not increased. The bending fatigue life and contact fatigue life of the gears are prolonged. A locking ring is embedded in a gear hub, and further reduces the axial size of the synchronizer. As a result, the gear shift stroke of a sliding gear sleeve isreduced, so that the length of a transmission rocker arm can be increased under the condition that the gear shift stroke of a cab remains unchanged. A large lever ratio can be realized, shifting ability of the synchronizer can be improved, gear-shifting force and de-gearing force of a driver can be reduced, and gearing is made more convenient.

Description

technical field [0001] The invention relates to an embedded compact high-performance synchronizer and a transmission. Background technique [0002] With the development of high-horsepower and high-torque manual transmissions, it has become extremely difficult for traditional synchronizers to achieve smaller transmission lengths through smaller installation distances and shift strokes, or to reduce the installation of synchronizers when the length of the transmission remains the same. It is also difficult to implement measures to increase the gear width by increasing the pitch to increase the bending fatigue and contact fatigue life of the gear. [0003] In addition, users have higher and higher requirements for the convenience of shifting, and drivers require lighter shifting force and shifting force, no impact and frustration during the shifting process, and reduced driving labor intensity. Contents of the invention [0004] In order to solve the technical problems of lo...
