Title:
INTELLIGENT EXTERNAL MAGNETORHEOLOGICAL SUSPENSION SYSTEM WITH CONTROLLABLE DAMPING, CONTROL METHOD AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/208155
Kind Code:
A1
Abstract:
Disclosed in the present invention are an intelligent external magnetorheological suspension system with controllable damping, a control method and a vehicle. The intelligent external magnetorheological suspension system comprises a suspension cylinder, connecting pipes, a magnetorheological control unit and an energy accumulator, wherein the magnetorheological control unit is located between the suspension cylinder and the energy accumulator, and all three are connected by means of the connecting pipes; a magnetorheological fluid is disposed between the suspension cylinder, the magnetorheological control unit and the energy accumulator; when the suspension cylinder is compressed and then extends, the magnetorheological fluid is conducted to flow back and forth by the suspension cylinder and the energy accumulator; when an external current is applied to the magnetorheological control unit, an electromagnetic field in the magnetorheological control unit promotes the magnetorheological fluid to "solidify", thereby affecting the flow speed of the magnetorheological fluid and the damping magnitude of the suspension system; and by means of increasing and decreasing the external current, the strength of the electromagnetic field is increased and decreased, so as to facilitate the adjustment of the damping of the system. By means of the present invention, the environmental adaptability, comfortability and system reliability of a vehicle can be effectively improved, the operation efficiency of the vehicle can be improved, the difficulty in terms of design and manufacturing processes can also be reduced, and thus costs can be reduced.
