Abstract

Official abstract text for this publication.

Brake system comprising a thrust rod ( 130 ) driven by the servobrake ( 200 ) and actuating the piston ( 110 ) of the master cylinder ( 100 ), the servobrake ( 200 ) being linked by a hydraulic actuator ( 270 ) to the control rod ( 230 ) of the brake pedal (PF). The servobrake ( 200 ) comprises an actuator piston ( 220 ) controlled by an electric motor ( 265 ) via a rack drive ( 260 ). A simulator chamber ( 250 ) delimited by the hydraulic actuator ( 270 ) is subdivided by an intermediate piston ( 240 ) into a rear volume (V 1 ) and a front volume (V 2 ), respectively delimited by the intermediate piston ( 240 ). A duct (L 1 ) links the rear volume (V 1 ) to a duct (L 2 ) linked to the front volume (V 2 ) by a first solenoid valve (EV 1 ) and the duct (L 2 ) to the tank ( 115 ) by a second solenoid valve (EV 2 ). The piston ( 240 ) is linked to the rod ( 130 ) bearing an abutment ( 132 ) to be thrust by the actuator piston ( 220 ).

First claim

Opening claim text (preview).

The invention claimed is: 1. A brake system with electric servobrake comprising a servobrake acting in a controlled manner on a master cylinder via a thrust rod driven by the servobrake and actuating a piston (primary piston) of the master cylinder, the servobrake being linked by a hydraulic actuator to the control rod of a brake pedal, characterized in that the servobrake ( 200 ) comprises an actuator piston ( 220 ) controlled by an electric motor ( 265 ) via a rack drive ( 260…
