Towing vehicle brake and air suspension system

摘要

The invention relates to a trailer brake and air suspension system with a provided with supply pressure from the reservoir of the air suspension system lifting / lowering valve for changing the level of the Anhägfahrzeugs by changing the amount of air in Tragbälgen the Anhägfahrzeugs, with a Anhängegebremsventil or Parklösesicherheitsventil for automatic braking of the trailer in demolition the supply line, with a release valve for releasing the automatic braking with decoupled trailer vehicle, with an actuation valve for a parking brake, with a spill valve over which a reservoir pressure vessel for the air suspension system is filled with a supply pressure supplied air spring valve to control the driving level of the trailer, and with an overload protection valve that vents the parking brake in proportion to the service brake ventilation when the parking brake is actuated and the service brake is additionally actuated. The function of the release valve (14 ') and / or the actuation valve (13') of the parking brake (11) and / or the overflow valve (9) and / or the overload protection valve (12) and / or the function of automatic braking in case of tearing off the supply line (Parking safety valve 3) is / are integrated in the lift / lower valve (17).
