Abstract

The invention relates to the technical field of braking, and provides a magneto-rheological brake and a vehicle. The magneto-rheological brake comprises a rotating shaft, a magneto-rheological brake assembly and a clutch assembly; the magneto-rheological brake assembly comprises a shell, a brake disc and a magnet exciting coil, wherein the shell is arranged on the rotating shaft in a sleeving mode through a bearing, and the shell is provided with an accommodating cavity and a liquid accommodating cavity; the brake disc is rotatably arranged in the accommodating cavity, and the outer edge of the brake disc extends into the liquid accommodating cavity; the magnet exciting coil is arranged on the shell; the clutch assembly comprises a fixed body part, a movable body part and a control part, wherein the fixed body part is fixedly connected to the rotating shaft; the brake disc is connected to the movable body part, the movable body part is matched with the fixed body part, and the movable body part has a connection state of being connected to the fixed body part and a separation state of being separated from the fixed body part; and the output end of the control part acts on the movable body part. When the magneto-rheological brake needs to carry out brake, the movable body part is in the connection state, and the brake disc rotates along with the rotating shaft; and when the magneto-rheological brake is in a non-braking state, the movable body part is in the separation state, the brake disc does not rotate along with the rotating shaft, and the situation that the braking effect is reduced due to the fact that magnetorheological fluid is always in a friction state to generate heat is prevented.

Description

technical field [0001] The invention relates to the technical field of braking, in particular to a magneto-rheological brake and a vehicle. Background technique [0002] Magneto-rheological fluid is a kind of intelligent material that can realize shape transformation under the action of a magnetic field. It is a suspension composed of tiny soft magnetic particles with high magnetic permeability and low magnetic hysteresis and non-magnetic liquid. When there is no external magnetic field, the magnetorheological fluid presents a low-viscosity suspension. Under the action of a magnetic field, the magnetic molecules in the magnetorheological fluid will be arranged in chains, showing a viscoelastic solid with high viscosity and low fluidity. When the external magnetic field changes, the arrangement of magnetic molecules also changes. [0003] The magneto-rheological brake is a brake with magnetorheological fluid as the medium, including magnetorheological fluid, brake disc, exc...
