Abstract

The invention discloses a water-cooled magnetorheological brake which mainly comprises a rotating shaft, a brake disc, magnetorheological fluid, a left sealing end cover, a right sealing end cover, a left cooling end cover, a right cooling end cover, an exciting coil, a non-magnetic ring, sealing rings and temperature sensors. The magnetorheological fluid is filled in a cavity formed among the left sealing end cover, the right sealing end cover and the non-magnetic ring; the left cooling end cover and the right cooling end cover are respectively fixed onto the left sealing end cover and the right sealing end cover by the aid of screws; annular flow channels are respectively arranged inside the left cooling end cover and the right cooling end cover, and fluid inlets and fluid outlets are respectively formed in the outer end surface of the left cooling end cover and the outer end surface of the right cooling end cover; the temperature sensors are mounted at the fluid outlets. The water-cooled magnetorheological brake has the advantages that heat generated by the magnetorheological brake can be transmitted outwardly via cooling fluid in the annular flow channels, and accordingly a radiating effect can be realized.

Description

technical field [0001] The invention relates to a magnetorheological brake, in particular to a water-cooled magnetorheological brake. Background technique [0002] Magnetorheological fluid is a kind of intelligent fluid material, which is a suspension composed of tiny soft magnetic particles with high magnetic permeability and low magnetic hysteresis and non-magnetic liquid. This kind of suspension exhibits low-viscosity Newtonian fluid characteristics under the condition of zero magnetic field; while under the action of strong magnetic field, it presents high-viscosity, low-fluidity Bingham fluid characteristics. [0003] As one of the applications of magnetorheological fluid, magnetorheological brake has the advantages of small size, low energy consumption, fast response and large braking torque. But at the same time, since the magnetorheological brake will generate a lot of heat during braking, it will change the characteristics of the magnetorheological fluid and finall...
