In a four-wheel vehicle with vertically independently movable wheels (2′, 2″, 3′, 3″), diagonally opposite wheels (2′, 2″ or 3′, 3″) are connected to one another by respective cables (9, 90) guided over deflection rollers (11 to 15).The traction cable mounting makes it possible to adapt the height of the wheels in the event of equal loading of the individual wheels independently of the terrain.
