Abstract
An axle weight distribution controller for maintaining the weight borne by the steering axle of a load-carrying vehicle. A load transducer attached to the steering axle produces an electrical signal that is compared with signals representing desired minimum and maximum loads to be borne by the steering axle. If the load borne by the steering axle falls outside of the predetermined load interval, the pressure in an air spring supporting a third axle is adjusted so as to redistribute the weight borne by each of the other axles in the vehicle and to bring the load borne by the steering axle within desired limits.
