Abstract: 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.degree.. 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.degree.. 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.
