In an axle suspension device for a vehicle with gas spring suspension and roll stabilization an essentially rigid stabilizer body is used which is hingedly connected in two points to the axle to be stabilized, each near one end thereof, and in two points to the vehicle frame, which latter connections are formed by substantially vertical hydraulic cylinders with piston rods, having a sliding bearing in the cylinders, which can absorb transverse forces, the cylinders or piston rods thereof being connected to the frame by rigid connections. A control system for such cylinders has a pressure transformer with a larger surface, which is directly or indirectly under the pressure of the gas in the gas spring system, and has a smaller surface, on which the hydraulic pressure in said cylinders acts in the opposite direction, said surfaces being connected for common movement, a control pressure exerted by a fluid acting on the other side of said larger surface in the same direction as said hydraulic pressure being variable to control this system depending on one or more parameters on the basis of driving or road conditions. All this allows a simple and reliable design, safety and adaptation of roll stabilizing to different conditions for maximum comfort.
Axle suspension device for a vehicle with spring suspension and with a roll stabilizer with an essentially rigid stabilizer element which in four points is hingedly connected to other parts, in two points to the axle to be stabilized, each near one end thereof, and in two points each with a substantially vertical connection to the vehicle frame which is variable in length under the influence of roll loads, said substantially vertical connections being hydraulic cylinders with piston rods, in which near the place where they come out of the cylinders the piston rods run through a sliding bearing in the cylinders, which bearing can absorb transverse forces, and in which the connections to the frame of the part of these cylinder-piston rod-combinations connected to the frame are rigid.
