Clutch driven plate and clutch with three-stage torsional vibration damping mechanism

Abstract

The invention discloses a clutch driven disc with three levels of torsion damping mechanisms. The clutch driven disc comprises a friction plate, a driven disc steel sheet, a pre-damping mechanism, a second-level damping mechanism and a main damping mechanism, the second-level damping mechanism is connected with the pre-damping mechanism and the main damping mechanism in series and comprises a second-level damping cover plate in riveting connection with the driven disc steel sheet, a second-level damping fin, a second-level damping belleville spring, a second-level damping shaft sleeve plate and second-level damping springs, the second-level damping fin, the second-level damping belleville spring and the second-level damping shaft sleeve plate are arranged between the driven disc steel sheet and the second-level damping cover plate, and the second-level damping springs are located in the second-level damping shaft sleeve plate. The design scheme of the independent two-level damping mechanism is adopted, independent rigidity and damping can be formed, and therefore the better damping effect is achieved.

Description

technical field [0001] The invention relates to a clutch, in particular to a clutch driven disc with a three-stage torsional damping mechanism. Background technique [0002] The structure of the traditional clutch driven disc with torsional vibration damping mechanism is as follows: figure 1 As shown, the friction plate 100 and the splined hub 106 are connected by damping springs (including the main damping spring 102 and the idle damping spring 103 ), which have tangential elasticity to eliminate high-frequency resonance and play a buffering role. Between the friction plate 100, the spline hub 106, and the damping plate 107, there is a vibration damping plate 104, which is elastically clamped by a disc spring 105 to play a role of frictional damping, and to keep the damping torque stable to absorb The engine outputs fluctuating energy and attenuates low-frequency vibrations. [0003] In the structure of the traditional clutch driven disc, there are only two damping stages...

Problems solved by technology

[0008] The object of the present invention is to provide a clutch driven plate with a three-stage torsional vibration damping mechanism, to solve the unstable operation of the clutch in the critical position between the pre-vibration damping level and the main damping level in the prior art problems, thereby improving the torsional vibration damping performance of the vehicle under certain small torque conditions, and making the torque characteristics of the input gearbox more stable

[0009] Another object of the present invention is to provide a clutch driven disc with a three-stage torsional vibration damping mechanism to solve the problems in the prior art that the damping effect of the intermediate stage is not good and the installation of the intermediate shock damping spring is difficult, so that each The stage damping mechanism can be better installed and combined to form independent stiffness and damping, so as to achieve better vibration damping effect
