Patent ID: 8371661

Claim:
A brake system comprising: an actuating device; a control and regulating device; an electromotive drive device; a piston-cylinder system; a non-hydraulic gearing device physically attached to a piston of the piston-cylinder system; a pressure line configured to couple a working chamber of a cylinder of the piston-cylinder system to a wheel brake; and a valve arranged in the pressure line and configured to be controlled by the control and regulating device, wherein the control and regulating device is configured for controlling the electromotive drive device using the movement and/or position of the actuating device, the drive device configured for adjusting the piston of the piston-cylinder system via the non-hydraulic gearing device, so a pressure is adjusted in the working chamber of the cylinder, wherein the piston is configured to generate a required change in pressure for power-assisted braking (PAB) and an anti-locking braking system (ABS), wherein, in the case of failure of the drive device, the actuating device is configured to adjust the piston or the drive device, and wherein, after achieving a required braking pressure in a brake cylinder, the control and regulating device is configured to close the valve and to open the valve to adjust to a new brake pressure.
