Electronically adjustable brake actuation system

Electromechanically actuated disc brake system

A brake system for automotive vehicles with electric drive is operable by an actuating pedal and uses hydraulic friction brakes to augment the braking effect generated by the electric drive motors. The coaction of the drive motors with the hydraulic friction brakes is controlled by an electronic controller. In order to largely conform the pedal characteristics of the mentioned brake system to that of a standard passenger car, an actuating pedal (5) is in force-transmitting and travel-transmitting connection with a spring (8) exhibiting a predetermined characteristic curve, and the master brake cylinder (11), uncoupled from the actuating pedal (5), is operable by an electromagnet (9) which is responsive to the controller (70). If the master brake cylinder accommodates two pressure cheers, a single valve is arranged in or on the master cylinder housing, and acts as both a bypass valve and a differential-pressure valve.

A control valve with a control slider (9) comprising bead-type areas (17, 18, 19), by means of which the control slider is slidably arranged in the cylinder bore (8). The areas (17) and (18) isolate the inlet (2) from the outlet (3), while the area (19) isolates the outlet (3) from the leakage oil port (4). The clearance between the areas (17) and (18) of the control slider (9) and the wall of the cylinder bore (8) is smaller than the clearance between the area (19) of the control slider (9) and the wall of the cylinder bore (8). The output pressure is kept within close tolerances with only minor leakage losses.

The spring guide rail has several centering fingers and a bottom rail and is made out of a one-piece sheet metal strip into which substantially rectangular recesses are punched so that a ladder-type structure is formed with a pair of longitudinal bars being interconnected by cross bars. By repeated bending operations around given longitudinal axes the two parts of the bottom rail are formed by the longitudinal bars and the centering fingers are formed by the cross bars. Between the sections of the cross bars folded to face each other there is a space and in the bottom rail area projections are arranged which ensure the spacing between the opposite parts of the bottom rail. Thus, a simple and stable spring guide rail with a safe guidance is provided for the vane lifting springs.

A rotary vane-type engine includes a rotor, a cam ring surrounding the rotor, and working vanes slidably disposed in radial slots of the rotor and engaging with one of their ends the inner contour of the cam ring. The vanes subdivide the space formed between the rotor and the cam ring into working spaces which are limited axially by side plates. Control ports provided in the side plates have throttle channels which extend in the rotor circumferential direction and connect the working spaces arranged on either side of the throttle channel with each other.
