AI Technical Summary

Technical Problem

In existing technologies, the clutch response speed is relatively slow, resulting in untimely gear shifts and affecting the smoothness of gear shifts.

Method used

Design a clutch device including a piston, a cylinder, a main shaft, a receiving component, and a first elastic component. The piston and cylinder are sleeved on the main shaft, and the piston and the inner wall of the cylinder form a dead cavity. The receiving component is slidably connected to the piston. The first elastic component moves the receiving component away from the cylinder. High-pressure gas rushes into the dead cavity and pushes the piston to slide along the main shaft. The receiving component drives the pressure plate to complete the clutch engagement and disengagement, keeping the dead cavity volume small.

Benefits of technology

It achieves rapid clutch response and timely gear shifting, improving the smoothness of vehicle gear shifting.

Abstract

The invention relates to the technical field of clutches, and discloses a clutch device which comprises a piston, an air cylinder, a main shaft, a bearing piece and a first elastic piece. After high-pressure gas is injected into the air cylinder, the high-pressure gas can be injected into the dead cavity, the high-pressure gas can push the piston to slide relative to the air cylinder in the length direction of the main shaft, the piston can overcome the first elastic piece and drive the bearing piece to move, and the bearing piece drives the pressing piece to move to complete closing and separating of the clutch. After friction is generated between the pressing piece and the clutch, the size of the dead cavity can still be kept small through the first elastic piece, the technical problems that in the prior art, a clutch is slow in response, and a vehicle is not smooth during gear shifting are solved, and the technical effect that the clutch is rapid in response and timely in gear shifting, so that the vehicle is smoother during gear shifting is achieved.
