ABSTRACT:
A wheel suspension for vehicles. The invention relates to both double axle vehicles and single axle vehicles. Feasible areas of use are: prams, carts (pulled manually or by a vehicle), walkers, wheel chairs, skateboards, luggage carts and motor vehicles. It is significant for the wheel suspension that the centre axles (15a,15b) of wheels (11a,11b) of a set of wheels are connected to elements (14a,14b) that extend in the travelling direction of the vehicle, that these elements (14a,14b) are hingedly/pivotally connected to a frame (1′) of the vehicle, that the centre axles (15a,15b) for adjacent wheels (11a,11b) are located at a certain distance from each other in the longitudinal direction/travelling direction (2) of the vehicle.
