Damper of vehicle damping mechanism

Abstract

The invention discloses a damper of an automobile damping mechanism, which is provided with a bottom cylinder body and a piston which is arranged in the cylinder body in a free reciprocating motion type and has the same shaft with the cylinder body; the bottom cylinder body consists of a damper body and a top cover; the piston consists of a piston rod which passes through the top cover and a bottom surface part which is matched with the damper body; the internal wall of the damper body is uniformly provided with a plurality of curve troughs which are convex in the middle, concave at two ends and symmetrical at the left and the right along the direction of the axis line; the curve formula of the curve troughs is that y is equal to a multiplied by the absolute value of x<3>; wherein, a is less than 1 and more than minus 1; furthermore, the more the quantity of the curve troughs is or the greater the inflation pressure in the damper body is, the greater the coefficient a is; the shape of the bottom surface part of the piston which moves up and down along the curve troughs is corresponding to the shape of the internal chamber of the damper body at the center of the curve troughs. The invention has the advantages that the structure is simple, the application and operation are simple, the invention can effectively relieve the problem of excessive acceleration which is also the impact and jounce problem of the vehicle body which is caused by the change of the upper and lower speed of the vehicle body, and the discomfort of the passengers is greatly lightened.

Description

technical field [0001] The invention relates to a damper, in particular to a damper suitable for a shock absorbing mechanism of an automobile. Background technique [0002] The shock absorbing system used in automobiles generally adopts plate type or spring type shock absorbing system. The elastic force of this kind of shock absorbing system will not change with the load, and it will easily cause fatigue after a long time of use, and lose its original elasticity. If the vibration is too large and broken, it is easily damaged, and it is troublesome and a waste of money to replace. At present, although automobile shock absorbers have many structures, they are roughly divided into two types with liquid and gas as the working medium. Most of the existing automobiles use liquid oil as the shock absorbing mechanism of the working medium, which mainly has the following two disadvantages: the one is that there is no oil between the upper end surface of the piston and the steel slee...
