Abstract: A helical gearing for driving an adjusting element, which may be an actuator or a piston of a piston-cylinder unit, is driven by an electric motor. The adjusting element may be moved along an axis. The drive apparatus has a rotor, or a translator rotatably mounted in a housing by a bearing and fixedly connected to the input of or formed integrally with the helical gearing. The output of the helical gearing is connected to or formed integrally with the adjusting element. An anti-twist means may prevent the adjusting element from twisting in the circumferential direction about the axis. The helical gearing and/or at least part of the adjusting element is/are formed to be transversely elastic to the axis of rotation, at least in one region.

Abstract: A brake system may include an actuation device that may actuate a first piston-cylinder unit to apply pressure medium to at least one brake circuit via a valve device, where a piston of the first piston-cylinder unit separate first and second working chambers; a second piston-cylinder unit, having an electromotive drive and a transmission to feed pressure medium to at least one of the brake circuits via a valve device; and a motor-pump unit having a valve device to feed pressure medium to the brake circuits. The motor of the electromotive drive of the second piston-cylinder unit and the motor of the motor-pump unit may be used jointly or independently of one another, under control of a control device. The motor-pump unit is connected via two hydraulic connections, one or both of which may incorporate separating valves, to the first and second working chambers of the first piston-cylinder unit.

The electromechanically actuatable wheel brake has a hydraulic control device having a piston-cylinder unit, the control piston of which serves for adjusting the brake piston and/or exerting a force on the brake piston. The control piston can be adjusted or a force can be exerted on the control piston.

Abstract: A diagnostic method, in particular to determine the leak tightness of at least one seal and/or one valve, for at least one component of a vehicle, wherein a piston cylinder unit, whose piston is driven by an electromotive drive, forms a pressure supply unit, wherein a control unit identifies the piston position and/or piston movement of the piston by means of at least one sensor and the pressure generated by the pressure supply unit or the motor current flowing through the drive by means of at least one sensor. During the diagnostic method, the control unit may be used to measure quantities relating to piston movement/position, pressure, and/or pressure variation.
