Abstract
A bus arranged in accordance with the present invention permits the boarding level to be minimized at bus stops without unduly reducing the ground clearance to be maintained during operation. When supporting struts are being extended at a bus stop, the bus will tilt forward about a horizontal transverse axis extending through these supporting points, so that the distance between the bus body and the roadway will considerably decrease in the forward portion of the bus. Short-circuiting the air suspension bellows of front and rear axles prevents the air bellows from countering the down-movement of the bus body with a restoring force. When passengers have boarded, the bus is restored to its horizontal position by retracting the supporting struts, with the air from the air bellows of the rear axle flowing back to the front axle.
