In a gas spring system for wheel suspensions including a tubular rolling bellows which is arranged between a wheel-carrying element and the vehicle superstructure and is mounted between a support element and a roll-on piston which includes a pressure-tight hollow space, the supporting element and the roll-on piston being guided on one another via a central thrust member, a control tube is arranged on the support element and provided with cross-over flow passages and the hollow space of the roll-on piston has a control collar which engages, with control play, the control tube at least in regions of the stroke for controlling the gas flow between the bellow interior and the hollow space as a function of the suspension stroke.
