Abstract

The invention relates to a suspension gear for a wheeled vehicle, in particular to a compound spring balanced suspension gear capable of damping uniformly, which comprises a guide arm arranged on each wheel shaft and articulated with the vehicle body, an energy accumulator, a coil spring, a plurality of hydro-pneumatic springs. The invention is characterized in that the compound spring brace comprising the coil spring and the hydro-pneumatic spring is provided on each guide arm respectively to connect with the vehicle body; at the same side, the cylinders of the hydro-pneumatic spring on the front and back wheel shaft arms are communicated through the pipelines, and the energy accumulator is connected with the pipeline. The suspension gear improves the damping performance of the automobile, which enables the automobile to have a smooth performance when riding on an uneven road.

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...
