Suspension system, automobile body stabilizing system and automobile

Abstract

The invention discloses a suspension system, an automobile body stabilizing system and an automobile and relates to a suspension system, an automobile body stabilizing system and an automobile capable of adjusting the height of an automobile body and the tire ground clearance. Hydraulic oil and high-pressure gas serve as the working mediums of the suspension system, the automobile body stabilizing system and the automobile, and the height of the automobile body and the tire ground clearance can be adjusted. The suspension system comprises a shock absorber body (1), a piston rod (3) and an oil cylinder (4). A suspension cylinder piston (5) and a lifting control oil cavity (6) are arranged in the oil cylinder. The automobile body stabilizing system comprises an automobile body stabilizing calculation controller and an oil way control device. All wheels are each provided with a suspension system. The oil way control device is connected with a first oil hole and a second oil hole through oil ways. The automobile body stabilizing calculation controller is connected with an automobile speed sensor, a steering angle sensor and an automobile body balance sensor. The invention further comprises the automobile provided with the suspension system or the automobile body stabilizing system.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an oil-gas and coil spring coupled shock-absorbing suspension system capable of adjusting the height of the vehicle body and the ground clearance of tires, a vehicle body stabilization system and an automobile. Background technique [0002] Under different driving conditions, the vehicle has different control requirements for the height of the vehicle body and the ground clearance of the tires. For example, when the vehicle is running at high speed, by reducing the height of the vehicle body and lowering the center of gravity of the chassis, the stability of the vehicle at high speed can be improved, and the wind resistance and fuel consumption can be reduced. ;When the vehicle is driving on a rough road at low speed, by raising the height of the vehicle body, the probability of suspension hitting the limit is reduced, and the vehicle's driving performance is improved; when th...

Problems solved by technology

However, due to the limited installation space of the oil-pneumatic suspension and the limited maximum capacity of hydraulic oil in the cylinder, the height adjustment range of the vehicle body is limited, and the ground clearance of the tires cannot be adjusted.

Some oil and gas springs are equipped with damping valves, which can provide certain damping, but this kind of damping is also not adjustable, and has limited effect on the comfort adjustment of the vehicle under different driving conditions.

Oil and gas sealing performance is the key characteristic of oil and gas springs. During use, when oil and gas leak due to various reasons such as wear of the seal pair, aging of the seals, scratches on the oil cylinder or seals by excess objects, and damage to the pipeline, it will directly cause The oil and gas spring loses its bearing capacity. In severe cases, the vehicle cannot continue to drive and must wait for rescue on the spot
