Embodiment Construction

[0010] The structure of the present invention is described in detail below in conjunction with accompanying drawing:

[0011] see figure 1 , this is a specific structure of the present invention, the piston 2 with the positioning bar 3 is installed in the working cylinder 1, one end of the piston rod 17 is fixed on the piston 2 by threads, and the other end of the piston rod 17 is passed through the working cylinder 1 one end. The sealing structure 15 and the bearing 16 protrude from the working cylinder 1, the other end of the working cylinder 1 communicates with the damping tube 6 made of non-magnetic material through the thread, and the other end of the damping tube 6 communicates with the compensation cylinder 9 through the thread. An electromagnet 5 is installed on the outer circumference of the damping tube 6, so that the magnetic field strength in the damping channel 10 is changed by the current entering the electromagnet 5, and the working cylinder 1 and the damping ch...

Abstract

The invention discloses a single-output rod double-cylinder magneto-rheological damper which comprises a working cylinder, a piston, a piston rod, a compensating cylinder, a damping tube and an electric magnet. The piston is mounted in the working cylinder; the piston rod is fixed at one end of the piston; the piston rod is extended out from the working cylinder through a sealing structure at one end of the working cylinder and a bearing; the other end of the working cylinder is communicated with one end of the damping tube; the other end of the damping tube is communicated with the compensating cylinder; a compensating piston is mounted in the compensating cylinder; a compensating spring or a compensating gasbag is mounted below a floating piston; the compensating spring or the compensating gasbag is fixed at the bottom of the compensating cylinder; and magneto-rheological fluid is filled in the working cylinder and the damping tube. The single-output rod double-cylinder magneto-rheological damper is an extrusion flow magneto-rheological damper with simple structure.

Description

technical field [0001] The invention relates to a magneto-rheological damper, in particular to a single-rod double-cylinder magneto-rheological damper. Background technique [0002] Ordinary shear valve magneto-rheological dampers use the piston as a magnetic field generator, and an excitation coil is wound in the middle of the piston; It has to be washed repeatedly by the magnetorheological fluid, and the heating of the excitation coil will also cause the magnetorheological fluid to heat up and change the performance of the magnetorheological fluid, so that the damping performance of the shear valve magnetorheological damper will also change. Change. Therefore, in order to overcome the deficiencies of the shear valve magnetorheological damper in these aspects, another type of magnetorheological damper has been developed based on the extrusion flow mode of magnetorheological fluid, such as: Chinese patent ZL03218419. 0 and Chinese patent 200610031978.X, two kinds of squeez...
