Multistage vibration reduction large-damping automobile clutch driven disc

Abstract

The invention provides a multistage vibration reduction large-damping automobile clutch driven disc. A body structure of the driven disc comprises a pre-vibration-reduction system, a second-stage vibration reduction system and a main vibration reduction system. A plurality of bosses are evenly distributed on a main vibration reduction steel sheet in the main vibration reduction system, large main vibration reduction damping is formed in cooperation with pressure elements on the two sides of a main vibration reduction shaft sleeve plate, the position of the main vibration reduction shaft sleeve plate in the axial direction is jointly limited, and space of the vibration reduction systems is independent. The multistage vibration reduction large-damping automobile clutch driven disc has the advantages that the main vibration reduction damping is provided by steel-to-steel friction of the main vibration reduction shaft sleeve plate and the bosses of the steel sheet, and large damping can be achieved through the larger friction radius and the higher friction coefficient; the multiple vibration reduction systems are provided with independent damping mechanisms and independent spring mechanisms, multistage vibration reduction is achieved by changing the design of the shaft sleeve plate, various driving working conditions of vehicles are matched within a wider range, the better vibration reduction performance is achieved, and the whole-vehicle comfort is improved.

Description

technical field [0001] The invention relates to a vibration damping system of an automobile clutch, in particular to a multi-stage damping large damping automobile clutch driven disc. Background technique [0002] The clutch is a key component connecting the engine and the gearbox in the car, which plays a role in transmitting torque and reducing engine vibration. Therefore, the performance of its damping system directly affects the comfort of the car. The stiffness in the damping system changes the vibration frequency, and the damping reduces the vibration amplitude, so as to achieve the purpose of improving the comfort of the car. Limited by factors such as the space and life of the damping system, the damping system cannot achieve arbitrary stiffness and damping. Usually, large stiffness and small damping are easy to achieve, but the engine has different working torques under different working conditions. A single large A driven plate with low stiffness and damping ...

Problems solved by technology

Limited by factors such as the space and life of the damping system, the damping system cannot achieve arbitrary stiffness and damping. Usually, large stiffness and small damping are easy to achieve, but the engine has different working torques under different working conditions. A single large A driven plate with low stiffness and damping cannot solve the problem of engine vibration under different operating torques under all working conditions, and this situation will be more prominent when encountering an engine with a higher maximum torque
