Abstract

The invention relates to a magnetorheological fluid brake with multiple magnetic poles. The brake comprises an end cover (1), an input shaft (2), a sealing bearing (3) and a base (8), a rotating disc (9) is arranged on the input shaft (2), magnet exciting coils (5, 6 and 7), an inner cylinder (10) and magnetic conductive blocks (11 and 12) are arranged in the base (8), a sealing ring (4) is arranged at the inner side of the end cover (1), and a sealing cavity formed by the end cover (1), the sealing bearing (3), the input shaft (2), the sealing ring (4), the inner cylinder (10) and the rotating disc (9) is filled with magnetorheological fluid. According to the magnetorheological fluid brake with the multiple magnetic poles, the multiple coils are designed, so that a magnetic field can be uniformly distributed on the cylindrical surface of the rotating disc, the magnetorheological material can provide larger shearing braking torque, the braking response speed is high, regulation and control are easy, the structure is simple and compact, disassembly and maintenance are easy, the machining difficulty is low, and miniaturization and large scale are facilitated.

Description

technical field [0001] The invention relates to the technical field of magneto-rheological fluid brakes, in particular to a magneto-rheological fluid brake with multiple magnetic poles, which belongs to the technical field of mechanical brakes. Background technique [0002] Magneto-rheological fluid is a new type of intelligent material. Under the action of an external magnetic field, a magneto-rheological effect occurs, and the initial Newtonian fluid properties instantly present solid-like properties. The magnetorheological process has the advantages of rapid response, reversible effect, low energy consumption, and strong adaptability. Using the precisely adjustable shear stress of magnetorheological fluid, apply magnetorheological fluid in the braking system, and adjust the braking torque of the brake by controlling the current in the magnetic field circuit, that is, the magnetorheological fluid brake. [0003] Magneto-rheological fluid microbrake is a high-tech that int...
