The invention discloses a height-adjustable independent suspension structure with a limiting function. The height-adjustable independent suspension structure comprises a suspension hanging plate, a suspension upper triangular arm, a suspension lower triangular arm, an elastic element, an adjustable spiral spring upper support and a limiting mechanism, wherein the suspension hanging plate is arranged on a longitudinal beam of a frame; the suspension upper triangular arm and the suspension lower triangular arm are arranged on the suspension hanging plate; the elastic element is arranged on the suspension lower triangular arm, and the adjustable spiral spring upper support is arranged on the elastic element; the adjustable spiral spring upper support comprises a support body, a first hinge mechanism, a second hinge mechanism, an elastic element fixing and supporting base, a third hinge mechanism, a supporting column, a supporting column upper fixing part, a supporting column lower fixing part and a fourth hinge mechanism; and the limiting mechanism comprises a lower limiting assembly arranged on the suspension upper triangular arm and an upper limiting assembly arranged on the adjustable spiral spring upper support. The adjustable spiral spring upper support is adjusted according to the lever principle, so that the position of an upper fixing point of the elastic element is changed, the whole vehicle height adjustment of the vehicle is achieved, meanwhile, the limiting mechanism is synchronously adjusted, and the whole vehicle height adjustment of the vehicle at the limiting position can be achieved.

    本发明公开了一种带有限位功能的高度可调独立悬架结构,包括设于车架纵梁上的悬架挂板、设于悬架挂板上的悬架上三角臂、悬架下三角臂、设于悬架下三角臂上的弹性元件、设于弹性元件上的可调螺簧上支座以及限位机构;可调螺簧上支座包括支座本体、第一铰接机构、第二铰接机构、弹性元件固定支撑底座、第三铰接机构、支撑柱、支撑柱上固定和支撑柱下固定以及第四铰接机构;限位机构包括设于悬架上三角臂上的下限位组件和设于可调螺簧上支座上的上限位组件;采用杠杆原理调节可调螺簧上支座,使得弹性元件的上固定点位置改变,进而实现车辆的整车高度调整,同时同步调整限位机构,使得车辆在极限位置也能够进行整车高度调整。
