ABSTRACT:
A vehicle bogie or similar wheel carrying unit which carries a vehicle body and which is connected to a device which holds the carrying unit at a predetermined distance from the ground, the vehicle body and/or carrying unit being provided with means for inclination of the vehicle around a generally horizontal axis in the direction of motion of the vehicle, wherein the vehicle body in its entirety is movable on the carrying unit in generally horizontal directions perpendicular to the direction of motion of the vehicle, the magnitude of said movement being controllable by a control device engaging the vehicle body. The carrying unit is provided with means pivotally supporting swinging arms to which the wheels are rotatably connected, each swinging arm being coupled to a device which holds the carrying unit at a predetermined distance from the ground and which device consists of a first cylinder-piston device on each side of the vehicle including a pressure fluid which counteracts the moments generated by the wheel pressures via the swinging arms. The cylinder-piston devices operably connect to the control device.
