An expansion device for drum brakes, which is floatingly and approximately centrally arranged between two substantially symmetrical brake shoes, the expansion device including at least two gear levers articulated to each other and each supported on a brake shoe, at least one of the gear levers of the expansion lock being coupled to an actuating element of an actuator system such that the brake shoes carry out an even, translationally directed expanding movement, which is converted by a gearing, in the direction of the brake drum. At least one of the gear levers of the spreader lock has a spring element integrated into it that can be elastically reversibly deformed by a brake application force about a defined elasticity &#x394;S of at least 1 mm in a defined manner.

Drum brake module which can be operated by electric motor

A pneumatic brake servo for motor vehicles having a servo housing, the interior of which is divided into at least one working chamber and at least one vacuum chamber by at least one axially movable wall which can be loaded with a pneumatic differential pressure, having a control valve which controls the differential pressure and is arranged in a control housing for connecting the working chamber to the vacuum chamber or to atmosphere. The movable wall includes a diaphragm plate and a rolling diaphragm, and the working chamber is sealed by a sealing ring which bears against the control housing and which is clamped in the radial direction in relation to a longitudinal axis of the brake servo. An actively loaded area of the movable wall is reduced by division of the working chamber into a prechamber and a main chamber to avoid stick/slip effects and reduce disruptive noises.

Brake servo

A servobrake for motor vehicles including a control valve which can be actuated by an electromagnet independently of an actuating rod which displaces a valve piston, which electromagnet actuates a third seal seat which makes possible ventilation of a working chamber. The third seal seat is formed on a sleeve which cooperates with the electromagnet, an annular element being provided which is arranged displaceably with respect to the third seal seat and which bears against the sleeve via an interposed elastic or compressible element. The annular element has means for guiding an air flow produced during normal braking in the direction of the working chamber.
