Wheel suspension with automatic camber adjustment

Independent suspension system for vehicles including a chassis and opposite wheels linked thereto by wheel suspension means,

• wherein the wheel suspension means of each wheel which oscillate during travelling operation comprise links connecting a wheel upright with the chassis and the wheel upright mounts the wheel rotatably around a wheel axis,
• wherein actuating means are provided between the chassis and a wheel suspension means, the actuating means comprising a camber cylinder having a piston/cylinder arrangement, and wherein
• a roll cylinder having a second piston/cylinder arrangement is provided acting between the chassis and an oscillating wheel suspension means,
• the roll cylinder is linked directly or indirectly to an articulation point on said oscillating wheel suspension means and to an articulation point at the chassis wherein a relative movement takes place between the articulation points during a roll movement of the chassis,
• the roll cylinder is double-acting and comprises two cylinder chambers mutually sealed by a piston,
• cylinder chambers of each roll cylinder of the wheel suspensions of the opposite wheels are coupled together in such a manner that the cylinder chambers decreasing during a roll movement of the chassis each communicate with a respective cylinder chamber increasing during the roll movement, and
• the cylinder chambers of the roll cylinders of the wheel suspensions of the opposite wheels are operatively coupled to the cylinder chambers of the likewise double-acting camber cylinder of the same wheel suspension in such a manner that the wheel camber is adjusted in order to increase a cornering force to which purpose the cylinder chambers of the roll cylinder which decrease during a roll movement of the chassis are coupled with the cylinder chambers of the camber cylinder which is increased and which causes a camber-adjusting impulse wherein the total volume of the respectively coupled cylinder chambers is constant.
