Abstract

The invention relates to a suspension device of a wheeled vehicle, in particular to a vehicle composite spring balanced suspension device capable of achieving balanced vibration reduction, which comprises a guide arm, an energy accumulator, a screw and The spring and the oil-gas spring are characterized in that a set of composite springs composed of the coil spring and the oil-gas spring are respectively arranged on each of the guide arms and are connected to the vehicle body; the oil-gas springs on the front and rear wheel guide arms of the same side The oil cylinders are connected through a pipeline, and a described accumulator is connected to the pipeline. The suspension device improves the vibration damping performance of the car, and has the obvious advantage of improving ride comfort when driving on uneven roads.

Description

technical field [0001] The invention relates to a suspension device of a wheeled vehicle, in particular to a novel suspension device capable of achieving balanced vibration reduction. Background technique [0002] Among the existing automobile suspension structures, many adopt coil spring suspension; some automobiles also adopt oil-pneumatic suspension. The coil spring has the advantage of simple structure, but when the load changes, the ordinary coil spring has the disadvantages that the natural frequency decreases with the increase of the load and the height of the vehicle body changes significantly. Hydro-pneumatic springs have the advantage of being highly controllable, but are too nonlinear (natural frequency increases with load). The linear helical spring and the over-strong nonlinear oil-gas spring are combined to form a composite spring, which bears the load together, and the spring characteristics of different properties complement each other to form an ideal chara...
