ARRANGEMENT FOR AN ELECTROHYDRAULIC BRAKE SYSTEM AND METHOD FOR CONTROLLING AN ELECTROHYDRAULIC BRAKE SYSTEM AND TANDEM MASTER BRAKE CYLINDER

摘要

The invention relates to a method and to an arrangement for the return of brake fluid from a pedal travel simulator (PWS) to the auxiliary brake circuit of an electrohydraulic brake system, and to an electrohydraulic brake system and a tandem master brake cylinder (THZ). According to the invention, in the emergency case, the return line (5) of the pedal travel simulator (PWS) which in the normal operation is linked with the brake fluid reservoir (6), is separated from the pressureless brake fluid reservoir (6) and is instead linked with the pressure end of the electrohydraulic pressure supply system (2) or at least with the pressure accumulator (3) of the electrohydraulic system.
