Description

Technical Field

[0001] The utility model relates to the technical field of automobile shock absorbers, in particular to an adjustable automobile magnetorheological resistance shock absorbing mechanism. Background Art

[0002] Adjustable automobile magnetorheological damping mechanism usually refers to magnetorheological shock absorber, which is a vibration reduction device that uses electromagnetic reaction to make real-time response to road conditions and driving environment based on input information from sensors that monitor vehicle body and wheel motion. The key part of the magnetorheological shock absorber is magnetorheological fluid, which is a magnetic soft particle suspension composed of tiny soft magnetic particles with high magnetic permeability and low magnetic hysteresis and non-magnetic conductive liquid. Under zero magnetic field conditions, it exhibits low viscosity characteristics; under strong magnetic field, it exhibits high viscosity and low fluidity liquid characteristics. When the magnetorheological fluid is injected into the electromagnetic coil in the shock absorber piston, the magnetic field of the coil will change its rheological characteristics, thereby generating a damping force with rapid response and strong controllability in the absence of an electromechanical control valve and a simple mechanical device. The vehicle-mounted controller continuously adjusts the damping force based on data obtained from multiple sensors.

[0003] In actual use, existing magnetorheological shock absorbers are usually located inside the vehicle body, but are not completely enclosed and are exposed to the outside to a certain extent. When the vehicle is driving on a road with poor road conditions, collisions with obstacles or gravel may cause damage to the shock absorber, and when the vehicle loses power unexpectedly, it is difficult to continue to supply power to monitor or maintain a stable damping state.

When driving in an environment with poor road conditions, it can provide good protection when impurities in the external environment collide with the structure.
