Abstract
A motor vehicle brake power proportioning device has a brake control force proportioned by a balance-beam-type device at a variable ratio onto different brake cylinders, particularly to the master brake cylinders of the front and rear axle of the motor vehicle. The balance-beam-type device is configured so that a lever arm adjustment, that is continuously a function of the brake control force, can be achieved for a constant course of the proportioning of the brake control force onto the brake cylinders. For achieving the lever arm adjustment as a function of the brake control force, at least one section of the balance-beam-type device is continuously deformable as a function of the brake control force.
