    Abstract: Arrangement for wheel suspension in a vehicle (1) including a vehicle frame (9) that bears at least two bogie axles (16, 17) which in turn each bear a wheel axle (5, 6), and also a first bogie element (18) and a second bogie element (19) which extend essentially in the longitudinal direction of the vehicle and are suspended in said vehicle frame (9). The invention includes at least one connection element (25; 41) extending essentially transversely to the longitudinal direction of the vehicle (1), which connection element (25; 41) is connected movably to at least one of the bogie axles (16; 17) and also to the bogie elements (18, 19), for transmission of a force which arises when relative movement takes place between the bogie axle (16; 17) concerned and said bogie elements (18, 19).
