Multi-stage vibration reduction and large damping automobile clutch driven disc

Abstract

The invention provides a multi-stage damping large damping automobile clutch driven disc, the main structure of the driven disc includes a pre-vibration damping system, a secondary damping system and a main damping system, the main damping system in the main damping system A plurality of bosses are evenly arranged on the vibrating steel sheet, and the large main damping damping is formed by cooperating with the pressure elements on both sides of the main damping bushing plate, which jointly limit the axial position of the main damping bushing plate to achieve The damping systems are spatially independent of each other. The advantage of the present invention is that the steel-to-steel friction between the main vibration-damping bushing plate and the steel sheet boss provides the main vibration-damping damping, larger friction radius and higher friction coefficient can realize large damping; multi-stage vibration-damping system It has its own independent damping mechanism and spring mechanism. By changing the design of the bushing plate, it can achieve multi-level vibration reduction, which can match various driving conditions of the vehicle in a wider range, realize better vibration reduction performance, and improve the comfort of the whole vehicle. sex.

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 cann...

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
