Patent ID: 8100415

Claim:
A wheel suspension for mounting on a frame of a vehicle, which, in its direction of travel, is arranged to be able to scale an obstacle; the wheel suspension comprises a link element arranged rotatably about a rotation point, to which rotation point a force (Gx) can be applied, via the frame, for propulsion purposes; the link element comprises a first wheel axle and a second wheel axle, wherein a first wheel is mounted on the first wheel axle and a second wheel is mounted on the second wheel axle, the second wheel axle being arranged behind the first wheel axle, the first and second wheels mounted on the first and second wheel axles, respectively, being disposed on either side of the rotation point; the second wheel axle serves as a moment axis about which the link element tends to rotate when a force is applied to the first wheel axle in a direction opposite to the direction of travel, wherein the link element acts as a lever arm by virtue of the rotation point being situated at a distance from an imaginary straight line intersecting the first wheel axle and the second wheel axle, the imaginary straight line being in a plane oriented transversely to the extent of the moment axis, and wherein the first and second wheels are mutually overlapping.
