Abstract

The invention discloses a sliding rail type air composite suspension, and aims to provide a novel multifunctional composite suspension structure which can effectively reduce vibration of a vehicle body, can adjust the minimum ground clearance, and is simple in structure and convenient to install. The device comprises a swing arm supporting frame, an air spring, an air spring air storage tank, a displacement sensor and an electric control unit. According to the sliding rail type air composite suspension structure designed by the invention, the swing arm support frame can move up and down to absorb the vibration of the tire to an axle when the tire is excited by a road surface to generate a large amount of vibration, so that the vibration of a vehicle body is effectively reduced, and the handling stability and the running smoothness of a vehicle are improved; and meanwhile, the electric control unit sends an inflation or deflation instruction to the air spring according to an identification signal of the displacement sensor, so that the trafficability and the high-speed stability are effectively improved.

Description

[0001] The invention relates to the technical field of automobile suspension, in particular to a slide rail type air composite suspension. Background technique [0002] The suspension system is an important system in a car. It connects the body and the wheels. Its function is to transmit the force and torque acting between the wheels and the body, buffer the impact of the unevenness of the road on the body, and then reduce The vibration of the car body to ensure that the car can run smoothly; the suspension system includes shock absorbers, shock absorbing springs, upper swing arms, lower swing arms and other components. The suspension system also determines the ride comfort and handling stability of the vehicle. When the car is running on the road, it is subject to vibration and impact due to changes in the unevenness of the road surface. Part of these impact forces are absorbed by the tires, and some are absorbed by the suspension system between the tires and the body, but th...
