Abstract
The present invention provides a method of and an apparatus for regulating an electrically regulated brake circuit of a multi-circuit brake mechanism with pressure medium activated brakes. To decrease the expense of such multi-circuit brake mechanism, the invention transforms the pressure, modulated by the brake actuating mechanism, to an electrical signal and regulates or co-regulates the electrically regulated brake circuit (II) by this electrical signal.
Claims9
An apparatus for regulating at least one electrically regulated brake circuit of a multi-circuit vehicle brake mechanism having a plurality of brakes which are activated by a fluid pressure medium, said apparatus comprising:
- (a) a brake actuating mechanism positioned on each vehicle which modulates a pressure that depends on at least one of an activating force applied to said brake actuating mechanism and an activating travel distance of at least one member of said brake actuating mechanism;
- (b) at least one electrically regulated brake circuit positioned on such vehicle to apply and release a portion of said plurality of brakes;
- (c) at least one brake circuit positioned on such vehicle which is activated by modulated pressure;
- (d) a pressure sensor positioned on such vehicle for transforming said modulated pressure into an electric signal, said electric signal depends on a magnitude of said modulated pressure;
- (e) wherein said electrically regulated brake circuit includes an electric brake pressure regulating device positioned therein;
- (f) wherein an output of said pressure sensor is connected to communicate said electric signal to an input of said electric brake pressure regulating device;
- (g) and wherein said pressure sensor is disposed in a housing of said brake actuating mechanism.
