Title:
MAGNETORHEOLOGICAL FLUID RETARDER AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/174496
Kind Code:
A1
Abstract:
Disclosed are a magnetorheological fluid retarder and a control method therefor. Valve characteristics of a magnetorheological fluid are utilized, and a high back pressure is generated by using a valve, such that braking is conducted, the braking torque is large, the response is fast, and the safety of a braking system is greatly improved. When braking is not required, the retarder does not work, and no magnet exciting coils are powered on; and when braking is required and the retarder receives a retarding braking signal, a magnet exciting coil module is powered on, the current is gradually increased, an oil port is gradually closed, and the back pressure in the retarder is gradually increased, thereby gradually increasing a braking force so as to achieve a retarding effect.
