Gapped magneto-rheological damper with single piston rod out

Abstract

The invention discloses a gapped magneto-rheological damper with single piston rod out. The magneto-rheological damper comprises a piston, a piston rod, a working cylinder, a compensating air bag and an external electromagnet, the piston comprises a rectangular piston body, two slide damping blocks and a slide damping block position adjuster, two short sides of the vertical section of the piston body are arc-shaped, two long sides of the vertical section of the piston body are axially provided with two symmetrical grooves through the piston body, the two slide damping blocks are mounted in the two grooves respectively and are fixed on the slide damping block position adjuster, the piston rod is provided with a central through hole, one end of the piston rod is fixed with the piston body, the other end of the piston rod extends out from the working cylinder through a sealing device and a sliding bearing which are at one end of the working cylinder, the compensating air bag is fixed at the inner bottom of the working cylinder, the external electromagnet is fixed on a shell of the working cylinder, and the piston is mounted in the working cylinder filled with magneto-rheological fluid.

Description

technical field [0001] The invention belongs to a magneto-rheological damper, in particular to a magneto-rheological damper with a cracked piston and a single rod. Background technique [0002] Magneto-rheological damper is an intelligent damping device. The structure of ordinary magnetorheological damper is to install a piston in the working cylinder, and fill the working cylinder with magnetorheological fluid, and adjust the pressure applied to the working cylinder by controlling the power supply. The electromagnetic field strength of the internal magnetorheological fluid changes the viscosity of the magnetorheological fluid in the working cylinder, so that when the magnetorheological fluid in the working cylinder is squeezed through the working gap between the outer peripheral wall of the piston and the inner peripheral wall of the working cylinder Different damping forces can be obtained, because the working gap between the outer peripheral wall of the piston and the in...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problem that the working gap between the outer peripheral wall of the piston and the inner peripheral wall of the working cylinder cannot be adjusted in ordinary magnetorheological dampers, making it difficult to expand the adjustment range of the damping force, the present invention proposes a new type of magnetorheological damper, namely Summary of the invention: a single-rod magneto-rheological damper with cracked piston, the technical scheme of the present invention is as follows:
