The invention discloses a sedimentation-preventing magneto-rheological shock absorber in the technical field of shock absorbers, comprising a shock-absorbing cylinder filled with magnetorheological fluid, and a piston slidingly connected in the middle of the shock-absorbing cylinder There are a plurality of circulation holes in the middle of the piston, a receiving hole is provided in the middle of the piston rod coaxially arranged with the piston, a nut is provided at the bottom of the receiving hole, and the bottom of the shock absorber is rotatably connected with the piston rod. The passive rotary rod of the shaft, the outer wall of the passive rotary rod is fixedly connected with stirring blades, the nut cooperates with the passive rotary rod to form a ball screw secondary structure, the outer wall of the shock absorber is fixedly connected with a cooling tube, and the cooling tube The gap between the heat sink and the shock absorber is filled with cooling fluid, and the outer wall of the heat sink is fixedly connected with a plurality of cooling fins; the invention is very effective in avoiding precipitation, and evenly stirs the magneto-rheological fluid to prevent the shock absorber from being too high in temperature and affecting the magnetic flow. The nature of the variable fluid ensures the damping effect of the shock absorber.
Description
technical field [0001] The invention relates to the technical field of shock absorbers, in particular to a precipitation-preventing magneto-rheological shock absorber. Background technique [0002] Magneto-rheological fluid is a suspension of magnetic soft particles. When the liquid is affected by an energized electromagnetic coil, the magnetic field of the coil will change its rheological characteristics (or generate fluid resistance), so that there is no electromechanical control valve and the mechanical device is simple. In the case of , it produces a damping force with rapid response and strong controllability. Magneto-rheological shock absorbers have the characteristics of high adjustable damping force, easy realization of computer variable damping real-time control, compact structure and small external input energy, etc., and are increasingly attached great importance to by the engineering community. [0003] When the existing magneto-rheological shock absorber is in ...
