Hydro-pneumatic spring and automobile

Abstract

The invention provides a hydro-pneumatic spring and an automobile, and belongs to the technical field of vehicle hydro-pneumatic suspensions. The hydro-pneumatic spring comprises a working cylinder, and the outer side of the first end of the working cylinder is rotationally connected with a connecting plate. A piston rod is arranged in the working cylinder, a piston is arranged at the end, located in the working cylinder, of the piston rod, and the other end of the piston rod is movably connected with a connecting ball hinge. An end cover is arranged at the second end of the working cylinder, and the piston rod is arranged in the end cover in a penetrating mode. According to the scheme, the connecting mode and the connecting position of the hydro-pneumatic spring, the frame and the axle are changed, and the connecting distance between the frame and the axle is shortened, so that the gravity center of the automobile is lowered, the stability of the automobile is improved, and the hydro-pneumatic spring can play a role in buffering impact when the automobile is impacted.

Description

technical field [0001] The invention relates to the technical field of vehicle oil-pneumatic suspension, in particular to an oil-pneumatic spring and an automobile. Background technique [0002] The stability of the car is an important criterion for evaluating the performance of the car. The stability of the car is related to the height of the center of gravity and the speed of the car. The speed of the car is determined by the actual driving situation. Therefore, if you want to improve the stability of the car, you must start by lowering the height of the center of gravity. The suspension system of the car determines the height of the vehicle body, and in the suspension system using the oil-gas spring, the length of the oil-gas spring finally determines the height of the vehicle body, which indirectly affects the center of gravity of the vehicle. Therefore, in some vehicles that require a low center of gravity, when the traditional oil-pneumatic spring cannot meet the requ...
