FIELD: transport engineering. SUBSTANCE: proposed axle lifting mechanism for vehicles with pneumatic suspension, whose beam 1 is secured on two longitudinal levers 3 one end of which is connected with vehicle frame for turning through cantilever 5 and other end rests on vehicle frame through pneumatic spring 6, is furnished with lifting device 9, 11. said lifting device 9, 11 rests on cantilever 5 and provides lifting of axle beam at operation and simultaneous bleeding of air from both pneumatic springs 6 supporting axle beam 1 on vehicle frame. To create axle lifting mechanism for all types of vehicles, particularly, for vehicles with disk brakes of axles, driven part of lifting mechanism 9, 11 is made resting on effort transmission member 13. When lifting device 9, 11 operates, member 13 adjoins corresponding longitudinal lever 3 from below, thus lifting the lever. EFFECT: simplified design, enlarged sphere of application. 16 cl, 8 dwg
