Abstract

The invention discloses a controllable automobile clutch based on magnetorheology. The controllable automobile clutch comprises a driven plate, a pressure plate, a transmission input shaft, a diaphragm spring connected with the pressure plate and a pushing device for pushing the diaphragm spring; the driven disk is in transmission connection with the transmission input shaft through a magnetorheological damper; the magnetorheological damper comprises a sleeve, a rotating shaft, a coil drum I and a coil drum II; the pushing device comprises a driving motor and a transmission mechanism for transmitting driving force of the driving motor to a diaphragm spring, a motor switch of the driving motor is arranged on the coil drum 1 and the coil drum II, and when the coil drum II moves towards the coil drum I to a set value, the motor switch is started. The controllable automobile clutch can adjust the magnitude of the magnetic field by changing the magnitude of the current, damping parameters are changed, the vibration damping control is achieved, and the control fatigue of a driver can be reduced.

Description

technical field [0001] The invention relates to a clutch for automobiles, in particular to a controllable clutch for automobiles based on magnetorheology. Background technique [0002] Automobile clutch is a commonly used automobile part, 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 damper used in the clutch is generally installed in the driven plate, so that The driven disc and the driven disc hub are elastically connected together by a torsion spring, which constitutes 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 pass through the damping spring to relieve the vibration. The torsional vibration is reduced, and at the same time, the torsional impact of the transmission system caused by starting or emergency braking can...
