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.
La présente invention concerne une vanne de transfert de poids proportionnel (54) destinée à décaler un rapport prédéterminé d'environ cinquante pour cent (50%) du poids d'un essieu à bouts (12) à un essieu moteur (10). La vanne de transfert de poids fonctionne en réponse à une indication de signal pneumatique d'un événement de traction. La vanne altère le rapport de pression de prise d'alimentation (82), associée aux coussins pneumatiques de suspension (14) de l'essieu moteur, qui est en faveur de la prise d'alimentation (84) associée aux coussins pneumatiques de suspension (16) de l'essieu à bouts. Lorsque le poids imposé sur l'essieu moteur approche une valeur maximale prédéterminée, la vanne de transfert de poids transfère moins de poids de manière à ce que l'essieu moteur ne soit pas surchargé.
