Braking device of a vehicle with electrical and by means of a pneumatic actuators notzuspanneinrichtung of a parking brake, as well as vehicle with such a braking device

摘要

Braking device (1) of a vehicle with a service brake device, the at least one rear brake pressure operation leading brake circuit (6) and a of an electric energy source is supplied with electric current has parking brake device, which firmly adjusting an electric brake value transmitter (26) and is controlled by the latter, and in which as a function of an actuation of the electric brake value transmitter is fixedly set (26) fixed brake control signals in an electronic control unit (9) are engaged, which, on the basis of the fixed brake control signals a magnet valve means (32) is actuated, which fixedly positioning of the pressure of the at least one active brake actuator (34) by means of pressure medium supply zuspannt, including:a) a pressure medium connection (44, 52) between the rear brake pressure operation leading brake circuit (6) and the fixedly set by the pressure medium actuated brake actuator (34), in order to rear brake pressure by means of the supply of the operation of brake circuit (6) the fixed adjustment capability of the brake actuator (34), to add tensioning,b) a in the pressure fluid connection (44, 52) switched valve means (46; 46 ''), by means of which the pressure fluid connection (44, 52) between the rear brake pressure operation leading brake circuit (6) and the fixedly set brake actuator (34) can be blocked off, characterized in thatc) the valve means (46) at least one of an electronic control unit (9) electrically controlled solenoid valve (50) which the rear brake pressure applied to an input terminal of said service (6) in the case of an intact electrical power supply or in the case of an intact electrical / electronic system of the parking brake device according to a blocking position with respect to an output terminal blocks and, in the case of a disturbed electrical power supply or in the disturbed electrical / electronic system of the parking brake device according to an open position at the output terminal transmits.
