Pneumatically operated pilot trailer control module with backup valve upstream from both control chambers

摘要

the invention concerns a pneumatic vorgesteuertes anhu00e4ngersteuermodul (1) of an electronic braking system of a motor vehicle - anhu00e4ngerkombination to produce a bremsdrucks for trailers depending on a fuu00dfbremsmodul (14) defined bremssignal,the first electronic control unit in a (13) produced electrical signal, and the other as a direct pneumatic signal to achieve a unterlegten security level.but under an electric bremskreises (l) the electrical signal to control a ventileinrichtung (6) to produce a fiscal pressure on a first steuerkolben a relaisventils (8) and in the context of a pneumatic bremskreises (ll) direct pneumatic signal generation and a fiscal pressure on a second steuerkolben of relaisventils (8) is provided.and with the pneumatic bremskreis (d) at least one of the electronic control unit (13) use backup valve (7) level.;the invention provides that the backup valve (7) ausgangsseitig with the first and the second steuerkammer steuerkammer connected and seen from fuu00dfbremsmodul (14) of the first and the second steuerkammer steuerkammer vorgeordnet.
