AI Technical Summary

Problems solved by technology

Due to the viscous dissipation of the liquid in the shock absorber and the heat generated by the built-in coil for a long time, the temperature of the liquid will rise rapidly. The rising phenomenon is more significant, which causes the variation of the working performance of the device, which brings challenges to the engineering application of magnetorheological devices

Embodiment Construction

[0022] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and contribute to its implementation.

[0023] Such as Figure 1 to Figure 5 As shown, the present invention provides a magneto-rheological shock absorber, which includes a shock absorber body and a damping and maintaining device connected to the shock absorber body. The first circulation device provides magnetorheological fluid to the shock absorber body and lowers the temperature of the magnetorheological fluid flowing out of the shock absorber body. Therefore, by setting the first circulation device to supply the magneto-rheological fluid to the shock absorber body, the weakening of the damping force caused by the thinning of the ma...

Abstract

The invention discloses a magnetorheological shock absorber. The magnetorheological shock absorber comprises a shock absorber body and a damping keeping device connected with the shock absorber body,and the damping keeping device comprises a first circulating device used for providing a magnetorheological fluid for the shock absorber body and cooling the magnetorheological fluid flowing out of the shock absorber body when the temperature of the shock absorber body reaches a set value. According to the magnetorheological shock absorber, the magnetorheological fluid is provided for the shock absorber body by arranging the first circulating device, and the phenomenon that heat is generated during working of the shock absorber, consequently, the magnetorheological fluid is diluted, and damping force is weakened is avoided so as to ensure the constant damping force.

Description

technical field [0001] The invention belongs to the technical field of shock absorbers, in particular, the invention relates to a magneto-rheological shock absorber. Background technique [0002] The temperature rise effect is a major challenge for the magnetorheological shock absorber from the laboratory to the large-scale engineering application. The temperature rise caused by the long-term continuous operation will affect the mechanical properties and stability of the shock absorber. Magnetorheological fluid is a smart material formed by suspending magnetic particles in a carrier liquid, and its viscosity and shear yield stress can reversibly change with an applied magnetic field. Since the material came out, it has attracted widespread attention and gradually entered the stage of engineering application, and a relatively mature commercial magnetorheological device has been developed. Magneto-rheological shock absorbers are the most widely used at present, and are used i...
