Embodiment Construction

[0019] Below in conjunction with accompanying drawing, patent of the present invention is described further.

[0020] Refer to attached figure 1 The present invention includes an electromagnetic coil 1, an outer magnetic core 2, a non-magnetic seal 3, a cylinder body 4, a bearing 5, a slider 6, a return spring 7, an output shaft 8, an electromagnetic valve 9, a seal 10, and a driven disk 11. Input shaft 12.

[0021] In the present invention, the input shaft of the auxiliary device is the output shaft of the friction clutch, and the output shaft of the auxiliary device is used as the input shaft of the transmission; the working cylinder is filled with magnetorheological fluid; the electromagnetic coil surrounds the outside of the working cylinder and is controlled by the ECU. The magnitude of the electromagnetic coil current and the magnitude of the current generation determine the viscosity coefficient of the magneto-rheological fluid, so that the joint is softer, smoother an...

Abstract

An auxiliary device of a friction clutch is characterized in that a working cylinder is in a disc shape, an input shaft is fixedly connected with the cylinder, an output shaft is installed in a through hole of a shell through a bearing, magnetorheological fluid is arranged in a cavity of the cylinder, the viscosity coefficient of magnetorheological fluid is influenced by the magnitude of current of a coil, and therefore the magnitude of loads loaded on a driven disc of the clutch is influenced, and the aim of making connection of the clutch smoother is achieved. A magnet exciting coil is fixed to an outer magnetic core which surrounds the outer side of the cylinder, and therefore the magnetic field distribution can be improved, and the auxiliary device works more stably; if the magnet exciting coil is damaged, the magnet exciting coil can be easily replaced, and therefore use performance of the auxiliary device is improved. Due to the fact that the controllability of magnetorheological fluid is high, the auxiliary device rapidly responds to the clutch. After the friction clutch is fully connected, a slide block overcomes the tensile force of a reset spring and is inserted into a machined groove in the cylinder, the output shaft is in rigid connection with the cylinder, the electromagnetic coil can be powered off at the moment, the rigid connection of a transmission system is kept, the auxiliary device does not need to be powered for a long time through the electromagnetic coil, and the high transmission efficiency and high stability of the transmission system are ensured.

Description

technical field [0001] The invention relates to an auxiliary device for a friction clutch, in particular to a device which uses magneto-rheological fluid to make the clutch engage more smoothly. Background technique [0002] The clutch is a component directly connected with the engine in the car transmission system. Its function is mainly to ensure the smooth start of the car, to ensure the smooth operation of the transmission system when shifting gears, and to prevent the transmission system from being overloaded. [0003] The use of the car clutch has a direct impact on the starting and shifting of the car. When the car starts or changes gears, if the clutch is engaged too quickly, it will easily cause the car to stall or not drive smoothly. This situation generally occurs in existing friction clutches. Usually, a hydraulic torque converter is used to overcome the shortcomings of traditional clutches, so that the operation of the car is simple, the starting shift is smooth...
