The membrane accumulator for a slip-controlled vehicle brake system is installed in a hydraulic connection between a wheel brake and a hydraulic pump and has a membrane (2) of elastic material. The membrane is acted upon by a preloaded spring (21) indirect...

Piston pump (10) has stepped piston (50,50') in a stepped bore (39,40), of the holding fixture (3), within a cylindrical socket (50,50'), which is movable in an axial direction Ax. Stepped piston is designed at one end (51,51') partially like hollow tubing...

An operating process for a vehicle brake unit comprises a motor pump unit to convey pressure means or raise pressure having a main brake cylinder, a receptacle for the pump and wheel brake hoses/pipes and an electromagnetic valve operated by an electronic ...

The arrangement has a motor (1) and a piston pump (2) whose piston (3) can be driven via an eccentric element (4) connected to the motor shaft (10) and is connected via a coupling ring (5). The motor has a holding plate (6) with a protrusion (7) that exten...

The drum brake is self-reinforcing, i.e. uses a self-servo effect, and it has a support for at least one frictional lining (2) which works in combination with one or more friction surfaces (22). It also has at least one equipment to operate the linings. Du...

The method for controlling or regulating a motor vehicle involves the steps of determining an absolute speed (vabs) of the motor vehicle, as well as further vehicle condition/status parameters, and simultaneously determining several acceleration intermedia...

The motor-pump unit has an electric motor (1) and a piston pump (2), the drive shaft (4) of the electric motor and the support axis (10) of the pump formed as separate components, with axial forces transmitted to the support axis via a triple ring bearing ...

The compensating reservoir (1) has one pref. two fastening parts (5,6) on the side facing the master cylinder. Each part has an opening (7,8), which is aligned with, or at right angles to a corresponding opening in the master cylinder. A fastening peg (9) ...

The method involves detecting the actual revolution rate of the unbraked wheels (2,3) to derive a demand revolution rate for the braked wheels (7,8) in a controller (9), determining wheel slip on the braked wheels and applying a non-locking braking force t...
