Suspension of vehicles for rugged terrain

摘要

The invention relates to the suspension of a vehicle for rugged terrain with a wheel or wheel-like ground engaging element, the ground-engaging surface of which has the shape of a body of revolution and which is journalled for free rotation on a primary axle, the primary axle being freely rotatable around a second axle which is connected with the frame of the vehicle. The secondary and primary axles make an angle alpha with respect to each other which is less than 90 DEG . Also with respect to a reference plane tau , perpendicular to a horizontal support plane and passing through the longitudinal axis of the vehicle at least one of said axles making an angle beta with the plane tau which is less than 90 DEG . The suspension according to this invention is a simple design and no additional control device is required for the adjustment of the travel gear when overcoming obstacles. The suspension may be used to advantage on vehicles which are power driven, as well as on vehicles which are not power driven and which are either pushed or towed.
