Abstract

The invention discloses a gear shifting booster. The gear shifting booster comprises an input shaft, an output shaft, a piston and a valve seat; the input shaft penetrates through the output shaft and extends into the piston, and the output shaft is connected to the piston; the valve seat is arranged in an inner cavity of the piston and sleeves the input shaft; the valve seat comprises a left valve seat body and a right valve seat body, wherein the left valve seat body and the right valve seat body are symmetrically arranged in the inner cavity of the piston; a valve seat spring is arranged between the left valve seat body and the right valve seat body and sleeves the input shaft; and one end of the valve seat spring is connected to the left valve seat body, and the other end of the valve seat spring is connected to the right valve seat body. According to the gear shifting booster, the valve seat spring is arranged between the left valve seat body and the right valve seat body, axial positioning of the left valve seat body and the right valve seat body is realized by utilizing the valve seat spring, deflection of the left valve seat body and the right valve seat body is avoided, and then failure of the boosting effect caused by air leakage of the gear shifting booster is avoided.

Description

technical field [0001] The invention belongs to the technical field of shift boosters, in particular to a shift booster. Background technique [0002] With the rapid development of the economy and the continuous increase of car ownership, road traffic conditions are deteriorating day by day. Frequent shift operations make drivers prone to driving fatigue. Matching shift boosters can greatly reduce shift force and improve driving comfort. As the core component of the mechanical transmission, the gear shift booster can greatly improve the gear shifting performance. It has the advantages of super long life, high reliability, servo assist, good follow-up and high safety. It will be the standard for future mechanical transmissions. with products. [0003] At present, the internal valve seat of the shift booster is easily deflected, causing the booster to leak air, resulting in failure or weak booster power. Contents of the invention [0004] Aiming at the technical problems e...
