Multi-disc type magnetorheological fluid clutch

Abstract

The invention discloses a multi-disc type magnetorheological fluid clutch and belongs to the field of magnetorheological fluid clutches. The multi-disc type magnetorheological fluid clutch comprises a coil, a coil baffle, a right side outer shell vent hole, a seal ring, a right side outer shell, an end cap, a left side outer shell, a driving shaft, a driven shaft, a master driving disc, an auxiliary driving disc, a slave driving disc, a master driving disc check ring, a slave driving disc check ring, a right magnetism conduction side plate, an outer magnetism separation ring, a left magnetism conduction side plate, a driving side plate which is integrally formed with the driving shaft and an inner magnetism separation ring which is connected with the driving side plate. The multi-disc type magnetorheological fluid clutch further comprises a heat sink which is arranged in the inner portion of the inner magnetism separation ring and fan blades which are arranged on the inner side of the driving shaft and are connected with the driving side plate, the heat sink is fixed between the driving shaft and the auxiliary driving disc, fan-shaped holes which are communicated with the driving side plate and the left side outer shell are formed in the positions of the driving side plate and the left side outer shell, and the positions correspond to the fan-shaped holes which are formed in the left magnetism conduction side plate, the heat absorption end of a heat pipe is deeply inserted into the inner portion of the driving disc, and the heat dissipation end of the heat pipe is provided with a heat dissipation wing. The multi-disc type magnetorheological fluid clutch has the advantages of being good in heat dissipation effect and being capable of working in a slip frequency state for a long time.

Description

technical field [0001] The invention relates to a multi-disk magnetorheological fluid clutch, which belongs to the field of magnetorheological fluid clutches. Background technique [0002] The traditional liquid viscous transmission uses the oil film shearing effect between the active and passive friction plates to transmit power. It can work in slippery conditions for a long time, carry out stepless speed regulation, and can realize the synchronization between the active and passive shafts. Transmission, and by changing the thickness of the oil film to control the size of the transmitted torque. The advantages are fast speed regulation, good stability, and stepless speed regulation. Its disadvantage is that it requires a huge oil supply system and a complex control system, which is bulky and expensive. [0003] Magneto-rheological fluid is a new type of intelligent material. Due to its excellent magnetorheological effect in a magnetic field, it has mature applications in ...
