A suspension (1 ) for a vehicle frame (7) which can climb over obstacles (9). The suspension (1) comprises a primary supporting means (11) for contact with a supporting surface (15), which is located behind a forward supporting means (17). The primary supporting means (11) serves as a fulcrum (m), about which the suspension (1 ), when negotiating an obstacle, tends to rotate with a moment lifting the vehicle frame (7). The forward supporting means (17) is arranged on the suspension (1 ) permanently elevated above the supporting surface (15) so that contact is avoided between the forward supporting means (17) and the supporting surface (15) when operating on an even surface, but is elevated permanently in such a manner that it can come into contact with said obstacles (9).
