摘要

The system of lifting of the shaft and load vehicle equipped with system of lifting of the axle. The present invention relates to a system for hoisting shaft (10) for a second directional axis (12) of a cargo vehicle (1) and a cargo vehicle (1) with a system of lifting of the axle (10).Such a system of lifting axle (10) comprises two springs (2,2 '), two pneumatic springs (3), and a control mechanism configured to drive and control the pressure of the pneumatic spring (3).The three elements - steel spring (2,2 '), a pneumatic spring (3) and the mechanism of pressure control, operate together to control the descent of the second directional axis (12) and the control of the pressure imposed on the surface of the ground.
