Abstract

The invention relates to an energy feedback self-control magneto-rheological shock absorber. The energy feedback self-control magneto-rheological shock absorber is composed of a piston rod, a working cylinder, a compensation device and a piston, wherein the working cylinder is divided into an upper cavity and a lower cavity through the piston , a damping passageway is arranged between the upper cavity and the lower cavity, an energy feedback cavity is formed in the piston, two magnetic poles are arranged on the two sides of the energy feedback cavity, the magnetic poles include the S pole and the N pole, a magnetic exciting coil is arranged between the two magnetic poles, the magnetic exciting coil is connected with a lead screw which penetrates through an inner hole of the magnetic exciting coil, the lead screw is matched with a nut fixed into the energy feedback cavity, and the lead screw is connected with the working cylinder in a rotating mode. The energy feedback self-control magneto-rheological shock absorber is simple in structure, free of signal delivery, and capable of autonomously controlling the current according to the road surface conditions, and has the energy conservation effect and the emission reduction effect.

Description

[0001] technical field [0002] The invention relates to an automobile shock absorber, in particular to a magneto-rheological shock absorber. [0003] Background technique [0004] Because of its damping force, magneto-rheological shock absorbers not only have the stepless controllability of active damping systems, but also have the safety and reliability of passive structures to a certain extent. The magneto-rheological shock absorber can realize the continuous adjustment of damping, and has the characteristics of high response frequency, obvious damping change, low working voltage, low energy consumption, simple structure of the adjustment device, and low cost. The application prospect in the frame is broad, and it has become one of the hotspots in the research and application of the current automobile industry. The working medium of the magnetorheological shock absorber is magnetorheological fluid, and its characteristic is that the yield strength increases with the inc...
