    摘要： Embodiments of a wheelchair and suspension system are provided. The suspension includes a drive assembly that is pivotably connected to a base frame at multiple locations. In one embodiment, the connection is via intermediary pivoting links or arms. Embodiments of the links or arms including rigid links, resilient links, elastic links, shocks, springs, gas cylinders and lockable gas cylinders (or combinations of the foregoing). The drive assembly can, via the pivot connections, pivot to accommodate and traverse variations and obstacles on ground surfaces.

    摘要： A suspension for a vehicle is provided. The suspension includes, for example, a frame, at least one drive assembly and at least one caster pivot arm. The at least one drive assembly and the at least one caster pivot arm are pivotally connected to the frame such that the drive assembly and the front caster pivot arm are pivotable relative to one another.

    摘要： A wheelchair suspension includes a frame, a drive assembly pivot arm, a drive assembly, a front caster pivot arm, a front caster, and a spring and shock absorbing assembly. The drive assembly pivot arm is pivotally connected to the frame. The drive assembly includes a drive wheel and is mounted to the drive assembly pivot arm. The front caster pivot arm is pivotally mounted to the frame and coupled to the drive assembly pivot arm. The front caster is coupled to the at least one front caster pivot arm. The spring and shock absorbing assembly is pivotally connected to the drive assembly pivot arm at a first pivotal connection and pivotally connected to the front caster pivot arm at a second pivotal connection. The first and second pivotal connections are positioned such that a majority of the force applied by the spring and shock absorbing assembly is applied to the drive wheel when the suspension is on a flat, horizontal support surface.
