Crack cylinder double-out rod magneto-rheological damper

Abstract

The invention discloses a crack cylinder double-out rod magneto-rheological damper which comprises a working cylinder, a piston and two piston rods. The working cylinder is composed of a working cylinder body, two identical sliding damping blocks, an adjusting screw and two end covers. The longitudinal section of an inner cavity of the working cylinder body is formed by externally adding a semicircle to each of the two symmetrical short sides of a rectangle, wherein the diameter of the semicircle is equal to the length of each short side of the rectangle. Two grooves are formed in two long sides of the longitudinal section of the working cylinder body in the axial direction, wherein the two grooves are symmetrical and penetrate through the working cylinder body. The two sliding damping blocks are arranged in the two grooves. One end of the adjusting screw penetrates through threaded through holes in the sliding damping blocks and is installed on one end cover in the working cylinder and the other end of the adjusting screw extends out of the working cylinder by penetrating through an adjusting hole in the other end cover. The shape of the longitudinal section of the piston is identical with the shape of the longitudinal section of the inner cavity of the working cylinder. A magneto-rheological fluid flowing gap is reserved between the outer peripheral wall of the piston and the inner peripheral wall of the working cylinder. A magnet exciting coil is wound in the middle portion of the piston.

Description

technical field [0001] The invention belongs to a magneto-rheological damper, in particular to a magneto-rheological damper with double outlet rods in a crack cylinder. 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 t...

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 magneto-rheological damper with double outlet rods in a crack cylinder, the technical scheme of the present invention is as follows:
