Description

Technical Field

[0001] The utility model relates to the technical field of magnetorheological dampers, in particular to a magnetorheological electric automobile damper assembly. Background Art

[0002] With the rapid development of the automobile industry, vehicle driving quality and safety have become the focus of consumers and automobile manufacturers. As an important part of the vehicle suspension system, the shock absorber plays a vital role in improving the vibration and impact during vehicle driving, and improving ride comfort and safety. As an advanced vibration reduction technology, the magnetorheological electric automobile shock absorber assembly has attracted widespread attention because it can achieve real-time adjustment of the damping force;

[0003] Traditional magnetorheological electric automobile shock absorber assemblies mainly adjust the damping force through electromagnetic control valves and fluid media. The electromagnetic control valve controls the flow speed and direction of the fluid medium by changing the magnitude and direction of the current, thereby adjusting the damping force. However, this adjustment method mainly depends on the response speed of the electromagnetic control valve and the flow performance of the fluid medium, and its adjustment range and accuracy are subject to certain limitations. Under extreme working conditions, such as high-speed driving, sharp turns or heavy loads, traditional magnetorheological electric shock absorbers may not be able to provide sufficient damping force, resulting in decreased vehicle stability, reduced ride comfort, and even potential safety hazards. Therefore, we proposed a magnetorheological electric automobile shock absorber assembly to solve the above problems. Utility Model Content
