Abstract
The invention concerns a device for maintaining at an adjusted level the chassis of a vehicle with variable suspension, comprising: means for variable unfolding (1) fixed by one of their ends on the chassis such that the other end rests, at least when these means are unfolded, on an axle (20) of the vehicle; first control means (14) for controlling the unfolding of the variable unfolding means (1); second control means (5, 9) for increasing the pressure of a first fluid contained in the elements of the variable suspension in response to a load increase applied to the chassis; and third control means (9) for reducing the pressure of the first fluid contained in the elements of the variable suspension in response to a load decrease applied to the chassis.
