The invention relates to a valve assembly and a method for controlling a liftable driven axle of a trailer, in which the driven axle is arranged in front of or behind a main axle, is arranged on the frame of the trailer via at least one load-bearing bellows support, and can be lifted or lowered by means of at least one lifting bellows. The valve assembly is configured such that the bellows pressure in the load-bearing bellows and the bellows pressure in the lift bellows can be adjusted independently of each other and automatically descend in the direction of the lane when the power supply is cut off. The valve assembly has: a first solenoid valve unit, which can be actuated by an electronic control unit, for steplessly adjusting the bellows pressure in the carrier bellows of the driven axle between the ambient pressure and the bellows pressure applied in the carrier bellows of the main axle; and a second solenoid valve unit, which can be actuated by an electronic control unit independently of the first solenoid valve unit, for switching the bellows pressure in the lifting bellows between the ambient pressure and the reservoir pressure.

    本发明涉及用于控制挂车的能抬升的从动桥的阀组件和方法,其中,从动桥布置在主车桥之前或之后,经由至少一个承载波纹管支撑布置在挂车的车架处,并且能借助至少一个升降波纹管抬升或下降。阀组件被构造成使得承载波纹管中的波纹管压力以及升降波纹管中的波纹管压力能彼此无关地调整并且在切断供电时从动桥自动朝车道的方向下降。阀组件具有:能由电子的控制器驱控的第一磁阀单元,其用于在周围环境压力与施加在主车桥的承载波纹管中的波纹管压力之间无级地调整在从动桥的承载波纹管中的波纹管压力;和能与第一磁阀单元无关地由电子的控制器驱控的第二磁阀单元,其用于使升降波纹管中的波纹管压力在周围环境压力与储备器压力之间转换。
