Description
Technical Field
The invention belongs to the technical field of automobiles, and particularly relates to a method for improving the running stability of an automobile.
Background
With the development of society, automobiles become indispensable vehicles for people to go out. When people drive automobiles, the people are difficult to avoid encountering bumpy road sections, so that the people feel uncomfortable during driving and serious traffic accidents can be caused when the people are serious. Therefore, it is desired to reduce the vibration of the automobile by means of the shock absorber.
The shock absorber is mainly used for inhibiting the shock when the spring absorbs the shock and rebounds and the impact from the road surface. When the shock absorber passes through the uneven road surface, although the shock absorbing spring can filter the shock of the road surface, the spring can still reciprocate, and the shock absorber is used for inhibiting the spring from jumping. The shock absorber is too soft, the vehicle body jumps up and down, and the shock absorber is too hard, so that too much resistance is brought, and the normal work of the spring is hindered. The vibration-proof device is mainly used for preventing the main engine, the auxiliary engine, various power machines and instruments from being influenced by vibration, and plays roles in reducing vibration and noise and preventing impact. The existing shock absorber has the problems of self-vibration phenomenon, easiness in transmitting intermediate-frequency vibration in the air, small horsepower, high noise, complex structure, poor shock absorption effect, complex installation and disassembly and short service life.
therefore, the shock absorber is designed with the adjustability of damping taken into account. The damping adjustment of the shock absorber is realized, and the shock isolation system has great control and application values. Generally speaking, there are two ways for the damping of the shock absorber to be variable, one is to adopt the special viscous liquid of magneto-rheological or electro-rheological fluid, and realize the change of the viscous resistance by the change of the viscosity; and the other method is to change the resistance by changing the flow area of the viscous liquid, thereby realizing the adjustable damping.
Some technical solutions for improving the driving stability of an automobile have been proposed in the prior art, and for example, a chinese patent with application number 201510053770 discloses an adjustable damping shock absorber, which includes a working cylinder, an oil storage cylinder, a piston rod, a piston assembly, a guide seat assembly, a bottom valve assembly, a bottom cover, an upper lifting lug and a lower lifting lug. The valve plate made of magnetic control type shape memory alloy and the piston throttling through hole realize the damping effect, the electrified electromagnetic coil arranged in the piston rod is connected with the outer end control circuit, the magnetic induction intensity around the piston can be changed by changing the current in the electromagnetic coil, the change of the radial size of the valve plate is realized, the size of the throttling area is changed, and the adjustable damping coefficient is realized.
According to the technical scheme, the shape memory alloy is integrated and applied to the bidirectional cylinder type shock absorber, so that the control is easy, the dynamic response speed is high, and the performance is stable. However, the shape of the shape memory alloy is changed by the alternate energization heating of the shape memory alloy in the technical scheme, the action time is long, and the action process of the damper can cause the temperature change of the oil liquid, so that the control effect is influenced, and the technical scheme is limited.
