Problems solved by technology

[0004] When the car travels from a flat road to a raised road, although this technical solution can realize the rapid increase of the vertical speed of the axle, avoid the vibration of the frame, and improve the stability of the car, but the structure uses oil to promote compensation. As the piston moves, as the displacement of the compensating piston gradually increases, the greater the damping it receives, the worse the impact filtering effect will be, which will cause the structure to have a greater decline in the shock absorption performance in the later stage of shock absorption, causing the vehicle to rebound. A sense of frustration is generated when driving, causing discomfort to the driver and occupants

Embodiment Construction

[0028] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0029] Such as Figure 1 to Figure 3 Shown, a kind of method for improving automobile running stability of the present invention, this method comprises the following steps:

[0030] Step 1: Install tire pressure monitoring in the car tires to monitor the air pressure inside the tires to avoid excessive tire pressure, increase the stiffness of the carcass, reduce the elasticity, and reduce the driving stability of the vehicle;

[0031] Step 2: Install the anti-skid control system on the car in step 1;

[0032] Step 3: install a gyroscope on the chassis of the car in step 2, the gyroscope is connected to the controller, the controller is associated with the brake system of the car, and the speed of the car is controlled in time according to the sta...

Abstract

The invention belongs to the technical field of automobiles, and particularly relate to a method for improving the travelling stationarity of an automobile. A shock absorber is used in the method andcomprises a cylinder, a first piston, a piston rod, a protective cylinder, a circulating valve, a rebound valve, a second piston, an inner spring, outer springs, guiding rods and a supporting disc. The guiding rods are connected to the bottom of the second piston. The bottoms of the guiding rods are fixedly connected with the supporting disc. The outer springs connected to the periphery of the cylinder in a sleeving mode are arranged between the supporting disc and guiding sleeves. The guiding sleeves are connected to the ends of the outer springs in a sleeving mode. According to the shock absorber, the guiding rods are arranged at the bottom of the second piston, and when the piston rod moves, the second piston is pushed to move downwards through the outer springs; and through linkage between the first piston and the second piston, on the one hand, force borne by the first piston can be reduced, and the service life of the first piston is prolonged, on the other hand, damping force borne by the second piston in the compression process does not fluctuate much, and the situation that the shock absorbing performance of the shock absorber degrades much at the later stage of a shock absorbing cycle is avoided.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to a method for improving the running stability of automobiles. Background technique [0002] When a car is running, its driving stability is restricted by many aspects, such as driving speed, tire pressure, suspension system and so on. In the automobile suspension system, the elastic elements vibrate due to the impact. In order to improve the ride comfort of the car, shock absorbers are installed in parallel with the elastic elements in the suspension. The working principle of the shock absorber is that when the frame (or body) and the axle vibrate and there is relative movement, the piston in the shock absorber moves up and down, and the oil in the shock absorber chamber repeatedly passes through different chambers. The pores flow into another cavity. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form a dampi...
