Abstract
There is disclosed herein a vehicle configuration comprising a chassis, at least one front wheel, two rear wheels, and a propulsion unit driving the rear wheels. The rear wheels are connected to the chassis by a wheel support assembly configured for allowing movement of each rear wheel relative to the chassis, a hydraulic cylinder connected to the chassis and the rear wheel supports, and a piston connected the rear wheel supports and the chassis. The piston dividing the hydraulic cylinder into fluidly connected first and second chambers such that movement of hydraulic fluid from the first or second chamber of a hydraulic cylinder to the respective first or second chamber of another hydraulic cylinder displaces the pistons of the hydraulic cylinders in opposing directions relative to the respective housings and causes the chassis to articulate with respect to the surface.
