Abstract

The invention relates to a motor-driven hydraulic clutch and an automobile, wherein a motor stator coil (2) is powered on to control a motor rotor (3) to rotate; a hollow part of the motor rotor (3) and a trapezoidal screw nut (28) are fixed together; the hollow part rotates to drive the trapezoidal screw nut (28) which is inside the hollow part; a trapezoidal screw rod (5) is matched with the trapezoidal screw nut (28), does rectilinear motion with rotation of the trapezoidal screw nut (28) and is used for pushing hydraulic oil in an oil cylinder I into an oil cylinder II and pushing a piston (19) to move; the piston (19) inside the oil cylinder II moves to drive a clutch push rod (16) to move; a displacement sensor magnetic ring (22) is mounted on the piston (19); a displacement sensor (36) is matched with the displacement sensor magnetic ring (22) to detect the displacement of the clutch push rod (16). The motor-driven hydraulic clutch disclosed by the invention is capable of realizing automatic clutching, and no extra hydraulic source is needed, so that the overall executing mechanism is compact in structure, convenient to install and relatively high in reliability.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to a motor-driven hydraulic clutch and an automobile. Background technique [0002] Hydraulic clutches are widely used in the automotive field because of their large torque transmission capacity, small size, no impact, and smooth starting and reversing. [0003] The automobile clutch is installed in the flywheel housing between the engine and the gearbox, and is fixed on the rear plane of the flywheel; the output shaft of the clutch is connected with the input shaft of the gearbox. This hydraulic clutch is mainly composed of a clutch push rod, a main pump, a slave pump and a clutch pedal. During the running of the car, the operator can step on or release the clutch pedal as needed, and use the hydraulic oil in the main pump and the slave pump as the transmission medium to transmit the force of stepping on the clutch pedal to the clutch push rod. The function is to temporaril...
