Abstract
The utility model belongs to the technical field of clutches, and particularly relates to a nonlinear torsion vibration damper. The nonlinear torsion vibration damper comprises a disc hub and a vibration reduction disc as well as a front friction plate and a back friction plate which are arranged on two sides of the disc hub and the vibration reduction disc, wherein a front clamping disc and a back clamping disc are arranged on the front side and the back side of the disc hub; a rubber damping spring is fixed on the disc hub; and the front clamping disc, the back clamping disc, the rubber damping spring and the disc hub are fixedly connected with each other. Through the adoption of the technical scheme, the nonlinear torsion vibration damper has the advantages of simple structure and high damping effect; and the rubber damping spring arranged in the inner chamber of the disc hub cannot move easily under a working state, thereby serving an elastic damping effect during compressive deformation. Therefore, the nonlinear torsion vibration damper has a stepless nonlinear torsion performance to start a vehicle smoothly; and the uncoaxiality during the mounting of a clutch and a transmission also can be compensated. Moreover, as no damping spring made of steel is adopted, the structure is simplified, rigid friction can be reduced effectively, and the buffering effect is better. Therefore, the nonlinear torsion vibration damper is suitable for mechanical vehicles under poor work environments; and the service life of the clutch can be prolonged effectively.
