The vehicle trailer, with a superstructure on a chassis and a tow shaft, has the road wheels sprung against the chassis by air springs (20a,20b,21a,21b). An air pressure adjustment sets the support load of the tow shaft and also the air pressure in one set of air springs in relation to the other set, and a pressure reduction valve (29a,29b) is between the front and rear springs. An air spring valve (26) sets the level of the air springs, with an inflow connection (25) linked to the compressed air supply, and at least one outflow connection (27a,27b) for the rear air springs and to the front air springs through the pressure reduction valves. |
