Abstract
A speed-responsive tag axle control system is disclosed including a comparison circuit which is operable when the rotational velocity of one driven wheel of a motor vehicle overruns the opposite driven wheel by a predetermined amount to simultaneously brake the faster driven wheel and shift the vehicle load from the tag axle wheels to the driven wheels. In one embodiment, a pressure fluid motor is connected between the tag axle and the vehicle chassis for normally transferring load from the driven wheels to the non-driven tag axle wheels, said motor being vented by said comparison circuit means to transfer the load back to the driven wheels upon the occurrence of a driven wheel overspin condition. In a second embodiment, the pressure fluid motor is connected between the driven wheels and the vehicle chassis, said pressure fluid motor normally being in the vented condition to cause load to be shared by the non-driven wheels, said motor being operable to the pressurized condition by the comparison circuit to effect transfer of load from the non-driven wheels to the driven wheels.
