A kind of automobile damping system

Abstract

The invention discloses an automobile damping system. The system comprises an automobile chassis, wherein a supporting block is fixedly connected to the bottom part of the automobile chassis; supporting grooves are formed in two sides of the supporting block; guide rods are fixedly connected to the upper sides and the lower sides of the inner walls of the supporting grooves; swinging rods sleeve the surfaces of the guide rods; a wheel is fixedly connected to one side, far away from the supporting block, of each swinging rod; a magnetorheological damper comprising a working cylinder is arrangedbetween the automobile chassis and the swinging rods; a lower mounting ring is mounted at the bottom end of the working cylinder by welding; an oil storing chamber is formed in the inner wall of theworking cylinder; a through hole is formed between the bottom end of the working cylinder and the bottom end of the oil storing chamber; a piston assembly is mounted in the working cylinder; mountingseats are mounted at two ends of the outer side of the working cylinder through glue in a sleeving manner; a rubber sleeve is mounted in the middle part of the outer side of the working cylinder through glue in a sleeving manner; and an abrasion-resistant coating is arranged on the outer surface of the working cylinder. The automobile damping system is scientific and reasonable in structure, safeand convenient to use, and outstanding in damping effect.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile shock absorption system. Background technique [0002] The shock absorption effect of the automobile shock absorption system of the existing automobile is relatively poor, and when driving on an uneven road surface, strong bumps are generated, which affects the operability of the automobile. In order to improve the shock absorption performance of automobiles, magnetorheological shock absorbers are more and more widely used at present. Magneto-rheological shock absorbers use electromagnetic responses to respond to road conditions and driving environments in real time based on input information from monitoring body and wheel motion sensors. Magneto-rheological fluid is a suspension of magnetic soft particles. After the electromagnetic coil in the shock absorber piston is energized, the magnetic field of the coil will change the rheological characteristics of the ...

Problems solved by technology

[0003] However, when the magneto-rheological shock absorber is used, there are the following disadvantages: when in use, when the current inside the electromagnetic coil is small and cannot generate a large magnetic field to affect the magnetorheological fluid, it will cause the shock absorber to The shock absorption effect is reduced, and when the vibration is large, it cannot be damped by the shock absorber, which makes the vehicle bumpy and affects the riding experience; moreover, when in use, the outside of the limit tube will be contaminated with dust, resulting in In the process of shock absorption, there is a jamming phenomenon, and it cannot be shock-absorbed; when the shock absorber is placed, it will cause the shock absorber to directly contact the ground, which will cause damage to the shock absorber and affect the normal operation of the shock absorber. Use; when the shock absorber is working, it will do reciprocating piston movement, which will generate a lot of heat and affect the service life of the shock absorber; in addition, the outer surface of the working cylinder is not provided with a protective coating, its aging resistance and durability The grinding performance is relatively poor, which shortens its service life
