Problems solved by technology

[0002] The magnetorheological damper is an intelligent damping device, and the damping force generated by it can be adjusted steplessly by controlling the power supply. Common shear valve magnetorheological dampers mainly include single-rod magnetorheological dampers and Double-rod magneto-rheological damper, the damping force generated by the double-rod magneto-rheological damper is symmetrical, while the damping force generated by the single-rod magneto-rheological damper is asymmetric; The requirement of the variable damper is that the damping force generated in the recovery stroke should be large, and the damping force generated in the compression stroke should be small, that is, the damping force generated by the magneto-rheological damper is required to be asymmetrical. Therefore, it is usually used in automobiles. A single-rod magneto-rheological damper is used as the damping device, but the asymmetry of the damping force of the existing single-rod magneto-rheological damper is difficult to increase due to the limitation of its own structure

Embodiment Construction

[0017] The structure of the present invention is described in detail below in conjunction with accompanying drawing:

[0018] see figure 1 , figure 2 and image 3 , a single-rod magnetorheological damper with a one-way channel, consisting of a working cylinder 1, a piston 5, a piston rod 19 and a compensation airbag 13, the working cylinder 1 is filled with a magnetorheological fluid 12, and the axis at one end of the piston 5 There is a large hole 11 for the circulation of the magnetorheological fluid 12, and there are four small holes 7 communicating with the large hole 11 around the piston rod 19 at the other end of the piston 5. A single hole 7 is installed inside the large hole 11 of the piston 5. To the valve bracket 9 and the one-way valve 10, a piston rod 19 is installed at the other end of the piston 5, an excitation coil 2 is wound on the piston 5, and a damping is formed on the inner peripheral surface of the working cylinder 1 and the outer peripheral surface of...

Abstract

The invention discloses a single-rod magnetorheological damper with a one-way channel, comprising a working cylinder, a piston, a piston rod and a piston rod volume compensating device, wherein the working cylinder is filled with magnetorheological fluids; a shaft center positioned on one end of the piston is provided with a large hole for communicating the magnetorheological fluids, and the periphery of the piston rod positioned on the other end of the piston is provided with more than two small holes communicated with the large hole; and a one-way valve is arranged on the opening of the large hole of the piston or in the large hole of the piston. Damping force generated by the single-rod magnetorheological damper with the one-way channel has higher asymmetry due to the one-way channel for flowing the magnetorheological fluids.

Description

technical field [0001] The invention belongs to a magneto-rheological damper, in particular to a magnetorheological damper with a single-exit rod with a one-way channel. Background technique [0002] The magnetorheological damper is an intelligent damping device, and the damping force generated by it can be adjusted steplessly by controlling the power supply. Common shear valve magnetorheological dampers mainly include single-rod magnetorheological dampers and Double-rod magneto-rheological damper, the damping force generated by the double-rod magneto-rheological damper is symmetrical, while the damping force generated by the single-rod magneto-rheological damper is asymmetric; The requirement of the variable damper is that the damping force generated in the recovery stroke should be large, and the damping force generated in the compression stroke should be small, that is, the damping force generated by the magneto-rheological damper is required to be asymmetrical. Therefore...
