Abstract

The invention relates to the technical field of brake devices, in particular to a magneto-rheological power braking device which can be applied to small and medium electric vehicles, project logistics vehicles, agricultural vehicles, mechanical power devices and the like. The device is formed by assembling a brake coil, a coil rack, magneto-rheological fluid, a brake pad rack, a brake pad, a brake shell, a power gear, a reversing gear, a reversing shaft, a lower shell and an upper shell; when a vehicle is braked, current is input into the brake coil, a magneto-rheological material in the brake is subjected to phase change, and the power gear, the reversing gear and the reversing shaft are positioned in a brake locking state; and when the vehicle starts, the current of the brake coil is cut off, the magneto-rheological material in the brake is demagnetized, a shaft of the brake pad is idled, and the reversing shaft is in a rotating state. The brake device solves technical problems to achieve light-weight product, simple structure, material reduction and intelligent control, the production cost can be effectively reduced, and powerful support is provided for promoting new materials, new technologies, new processes and technical upgrade of products.

Description

[technical field]

[0001] The invention relates to the technical field of dynamic braking devices, in particular to a magneto-rheological dynamic braking device and its braking method and application, which are suitable for small and medium-sized electric vehicles, engineering logistics vehicles, agricultural vehicles, and lifting and transporting vehicles , Marine driving devices, mechanical power devices, etc. [Background technique]

[0002] Magnetorheological fluid is a new type of phase change material. It is a magnetic particle suspension mixed with high magnetic permeability and low hysteresis (micron or even nanoscale) soft magnetic particles and non-magnetic liquid. When there is no magnetic field, the suspended particulate iron particles move freely with the liquid; when a magnetic field is applied, these suspended particulate iron particles are attracted to each other, forming a series of chain structures from one pole of the magnetic field to the other pole. At thi...
