<p>The present invention relates to a wheel suspension for mounting on a frame (3) of a vehicle, which, in its direction of propulsion, is arranged to be able to scale an obstacle (7), the wheel suspension (1) comprises a link element (9) arranged rotatably about a rotation point (R), to which rotation point (R), via the frame (3), can be applied a force (Gx) for propulsion, the link element (9) comprises a first and a second wheel axle (11, 13), the second wheel axle (13) serves as a moment axis (X) about which the link element (9) tends to rotate when a force (F) is applied to the first wheel axle (11) in the direction opposite to the direction of travel. The link element (9) acts as a lever arm by virtue of the rotation point (R) being situated at a distance from an imaginary straight line (L) intersecting the first and the second wheel axle (11, 13) and in a plane transversely to the extent of the moment axis (X).</p> |
