摘要

Lifting axle valve for controlling the lift of the functions of a vehicle with a plurality of rear axles, of which at least one rear axle as the driving spindle and at least one further rear axle is used as a lifting axle, with supporting bellows of the drive shaft and carrying bellows of lifting axle, as well as at least one lifting bellows for raising the lifting axle, characterized in that, in order to be - and bleeding of the bellows (2, 2 '') of the lifting axle a first and second solenoid valve (21, 22; 121, 122) the support bellows (1, 1'') of the drive shaft and the support bellows (2, 2 '') of the lifting axle are arranged in series and at least one pneumatically operable valve (31; 131) to the - and bleeding of the lift bellows (3) of the lifting axle is provided, wherein a pneumatic control terminal of the pneumatically operated valve (31, 131) via a pneumatic pilot control (8) of at least one of the solenoid valves (21, 22; 121, 122) is switchable pressure in such a way that the pneumatically operating valve (31; 131) the lifting bellows (3) or vented be -.
