The invention invention discloses a double-guide non-contact type magneto-rheological shock absorber. The double-guide non-contact type magneto-rheological shock absorber comprises a cylinder barrel;a piston rod is arranged in the cylinder barrel; one end of the cylinder barrel is open; one end of the piston rod extends out of the open end of the cylinder barrel; an upper guider is fixedly arranged at the end part of the open end of the cylinder barrel; a lower guider is fixedly arranged in the cylinder barrel; a magnetorheological fluid area is arranged between the lower guider and the upperguider; magnetorheological fluid is arranged in the magnetorheological fluid area; an electromagnetic coil is arranged on the section, located in the magnetorheological fluid area, of the piston rod;and the piston rod is connected with the upper guider and the lower guider in a sliding mode. According to the double-guide non-contact type magneto-rheological shock absorber, friction force generated by lateral force can be well overcome, and therefore, the problems that the shock absorber is not smooth in operation and short in service life due to the fact that the lateral force is too large are solved.
Description
technical field [0001] The invention relates to the technical field of shock absorbers, in particular to a double-guided non-contact magneto-rheological shock absorber. Background technique [0002] In the magneto-rheological shock absorber, the guide of the piston rod is usually guided by the guide at the upper end and the piston at the lower end, such as Figure 5 As shown, the piston 60 is usually fixedly installed below the piston rod 20 and moves up and down together with the piston rod 20 , and the outer surface of the piston 60 is generally in frictional contact with the inner wall of the cylinder 10 . In some automobile suspension structures (such as MacPherson suspension), the shock absorber often bears a large lateral force, and the lateral force will cause the shock absorber to have a large friction force during operation. Friction will not only cause the shock absorber to run stuck, but also cause rapid wear of the piston rod, piston, oil seal, and sliding bearin...
