<p>A proportional load transfer valve (54) is disclosed to shift a predetermined ratio of approximately fifty percent (50%) of the weight on a tag axle (12) to the drive axle (10). The load transfer valve acts in response to a pneumatic signal indicative of a traction event. The valve alters the ratio of supply port (82) pressure associated with the air suspension bags (14) of the drive axle that is forwarded to the delivery port (84) associated with the air bag suspension assembly (16) of the tag axle. As the weight imposed on the drive axle approaches a predetermined maximum, the load transfer valve transfers less weight so that the drive axle is not overloaded.</p> |
