Vehicle suspension and vehicle

Abstract

The invention relates a vehicle suspension which comprises an oil cylinder, energy accumulators and damping adjustment units, wherein a rodless cavity of the oil cylinder and a rod cavity of the oil cylinder are respectively connected with one energy accumulator; one damping adjustment unit is arranged between the rodless cavity of the oil cylinder and the corresponding energy accumulator, and the other one damping adjustment unit is arranged between the rod cavity of the oil cylinder and the corresponding energy accumulator. The vehicle suspension has the beneficial effects that the two energy accumulator and corresponding valve banks are arranged, so that rigid and continuous adjustment is realized, the side-tipping resistance and side-turnover resistance of a vehicle are improved, and the comfort, safety and control stability of the vehicle are greatly improved; the capacity of a general gas chamber of the energy accumulator communicated with the rodless cavity of the oil cylinder is increased, so that the rigidity of the suspension is reduced, the suspension is relatively soft, and the vehicle is relatively stable and comfortable in running.

Description

technical field [0001] The invention belongs to the technical field of automobile suspensions, and in particular relates to a double air chamber active control oil-air suspension. Background technique [0002] The automobile suspension system is like the human legs, which is of great significance to the driving safety, comfort and handling stability of the automobile. Suspension is a key component for isolating road excitation during driving. The damping and stiffness of traditional passive suspension cannot be adjusted after the design is completed. The ride comfort and handling stability of the vehicle cannot be balanced. It is an interconnected oil-pneumatic suspension, which improves the anti-rolling performance through the interconnection of the upper and lower oil cylinders of different wheel suspensions, and evenly distributes the multi-axis vehicle wheel load, but the suspension stiffness and damping cannot be adjusted. The ride comfort and driving safety of the who...
