Abstract

The invention discloses a vehicle collision magnetorheological shock absorber. The vehicle collision magnetorheological shock absorber comprises a working cylinder, a percussion piston, a percussion piston rod and at least one damping tube, wherein one end of the percussion piston rod is fixed with one end of the percussion piston; the other end of the percussion piston rod is extended out of theworking cylinder through a sliding bearing at one end of the working cylinder; one end of the damping tube is fixed to the bottom of the working cylinder and is communicated with the working cylinder; a sliding piston is arranged at an opening at one end, at the communication position of the damping tube and the working cylinder, of the damping tube; a sealing baffle is arranged at the tail end of the damping tube; a circular hole is formed in the center of the sealing baffle; a sealing diaphragm is fixed in the circular hole; silicone oil is filled between the sliding piston of the damping tube and the sealing diaphragm; a permanent magnet is arranged on the outer circumference of the damping tube; one end of the percussion piston is fixed with the percussion piston rod; the sliding bearing and a sealing ring are arranged on the outer circumference of the damping tube; and magnetorheological fluid is filled in the space of the other end of the percussion piston rod and the bottom of the working cylinder.

Description

technical field [0001] The invention belongs to a shock absorber, in particular to an automobile collision magneto-rheological shock absorber. Background technique [0002] With the increase in the number of automobiles in our country, the probability of automobile collisions has also increased greatly. In order to reduce the damage caused to vehicles and occupants when automobiles collide, people have developed various automobile collision shock absorbers. For example, the Chinese patent application number is: The "automobile collision piston shock absorber" of ZL93245003.2, and the Chinese patent application number: "a kind of automobile collision protection shock absorber" of ZL200420087894.9; because the "automobile collision piston shock absorber" provides constant damping Force, and "a kind of automobile collision protection shock absorber" provides elastic shock absorption, so the use of these automobile collision shock absorbers can play a certain role in reducing t...
