The invention provides an automobile magneto-rheological damper. The automobile magneto-rheological damper comprises a cylinder body, a piston assembly and an electromagnetic assembly, wherein magneto-rheological liquid is arranged in an accommodating cavity of the cylinder body; the inner wall of the cylinder body is equipped with a first threaded part; the piston assembly comprises a push-pull main rod, a rotary sleeve and a piston; the rotary sleeve is movably connected to one end of the push-pull main rod; the rotary sleeve is inserted into the cylinder body; the piston is fixedly arrangedon the rotary sleeve; a second threaded part which is matched with the first threaded part is arranged on the outer side wall of the piston; the electromagnetic assembly sleeves the cylinder body forgenerating magnetic fields to change rigidity of the magneto-rheological liquid in the cylinder body; and the electromagnetic assembly is connected with the push-pull main rod to move back and forthalong with the push-pull main rod. In use, the automobile magneto-rheological damper can enhance mobility of the magneto-rheological liquid, prevents the magneto-rheological liquid from precipitatingto affect work of the damper, and guarantees damping performance of the damper.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to an automotive magneto-rheological shock absorber. Background technique [0002] At present, most of the shock absorbers used in automobile suspension are passive, and the damping coefficient of the shock absorber cannot be changed according to the road condition information, so the comfort of passengers is not strong during the ride. With the discovery of magnetorheological fluid, it provides a new direction for active shock absorber research. [0003] Magnetorheological fluid is a suspension formed by dispersing and dissolving non-colloidal fine particles in an insulating carrier liquid, and its rheological behavior can be controlled with the change of an external magnetic field. In actual use, although anti-precipitation is added to the magnetorheological fluid, the precipitation phenomenon still exists, and in severe cases, the shock absorber cannot be used normally. Con...
