Abstract:
The present disclosure includes independent suspension systems or members, as well as wheeled skid steer loaders or other power machines including the same, that couple each wheel to a machine frame using a four-bar linkage, with the four bars including the frame of the machine, an upper control arm, a lower control arm, and a wheel carrier link. Each control arm is pivotally attached to both the machine frame and one end of the wheel carrier link. The four pivots between the control arms and the wheel carrier link are configured to all be contained within cylinder defined by the outer diameter of the wheel rim, allowing for a compact structure with the wheel carrier link and at least part of the control arms being positioned within this volume when the loader is in a resting position.
