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 puts forward a high-capacity embedded conical-surface synchronizer and a transmission adopting the synchronizer so as to solve the technical problems that gears of high-torque transmissions are relatively short in lift and users require easier and more convenient gear shifting. According to the synchronizer and the transmission, a circular boss with the inner wall being a conical surface is arranged on a gear assembly, and an outer friction ring of the synchronizer is embedded in the circular boss, so that the axial mounting distance of the synchronizer is reduced, the width of agear can be increased under the condition that the total length of the transmission is not increased, and the bending fatigue and contact fatigue life of the gear is prolonged; a locking ring is embedded in a gear hub, and the axial size of the synchronizer is further reduced, so that the gear engagement stroke of a sliding gear sleeve is reduced, the length of a rocker arm of the transmission can be allowed to be increased under the condition that the gear engagement stroke of a cab is unchanged, the large lever ratio can be realized, the gear shifting ability of the synchronizer is improved, the gear engagement force and the idling force of a driver are reduced, and gear engagement is easier and more convenient.

Description

technical field [0001] The invention relates to a large-capacity embedded cone 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 low gear...
