    摘要: A wheeled transport device, such as luggage, a trash can, a garden cart or other hand cart configured to be manually wheeled in an inclined position by a pedestrian user, includes a collapsible handle at one end and wheels at the other end. The wheels are independently connected to the device by respective suspensions that exhibit a compliance, in response to forces applied to their respective wheels by the surface in a direction opposing wheel motion, selected to sufficiently alter suspension geometry to temporarily change an attitude, such as toe, camber or caster, of their respective wheels to counter a tendency of the device to overturn in response to the applied forces.
