Magneto-rheological torsion damper of clutch and clutch with same

Abstract

The invention discloses a magneto-rheological torsion damper of a clutch and a clutch with the same. The magneto-rheological torsion damper comprises a sleeve and a torque input part, wherein a containing cavity is formed in the sleeve, and the torque input part is fixedly connected with the sleeve and inputs torque. The magneto-rheological torsion damper further comprises an elastic vibration damping element and a magneto-rheological damper part, wherein the elastic vibration damping element can buffer vibration through elastic compression when the torque is input, the magneto-rheological damper part rotates inside the annular containing cavity to generate magneto-rheological damping force under the force transmission of the elastic vibration damping element, and the annular containing cavity is filled with magneto-rheological fluid media. The magneto-rheological torsion damper has the advantages of being compact in structure, high in adaptability, small in energy dissipation and the like, can achieve the functions of a traditional torsion damper of the clutch, and meanwhile can solve the problem that damping parameters of an existing driven disc type torsion damper are uncontrollable.

Description

technical field

[0001] The invention relates to the field of clutch damping, in particular to a clutch magneto-rheological torsional shock absorber and a clutch thereof. Background technique

[0002] The clutch is usually installed between the engine and the transmission, its active part is connected with the flywheel of the engine, and the driven part is connected with the transmission. The torsional shock absorber used in the clutch is installed in the driven plate, so that the driven plate and the driven plate hub are elastically connected together by a spring to form the buffer mechanism of the shock absorber. So that the torque transmission from the engine to the driving wheel, or from the driving wheel to the engine, must go through the damping spring, which relieves the torsional vibration, and at the same time can quickly reduce the torsional impact of the transmission system caused by starting or emergency braking. And it is conducive to the soft engagement of the ...
