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.
