An improved inter-axle differential locking clutch is provided that aligns the actuator and the clutch member thereby reducing space and material requirements in the axle assembly housing. The clutch also eliminates the need for a pushrod and shift fork thereby reducing tooling and production costs, as well as eliminating issues associated with misalignment of the piston and pushrod, relative rotation of the shift fork and clutch member, and tipping of the shift fork. The clutch includes one or more pistons disposed within either the axle housing or a carrier supporting the input shaft bearing. Fluid pressure actuates the pistons against a clutch member causing selective engagement between the clutch member and either a side gear driven by the inter-axle differential or a differential case housing the differential gears of the inter-axle differential.
Un embrayage de blocage du différentiel interponts est fourni qui aligne l~actionneur et l~élément de l~embrayage, de ce fait réduisant les exigences en espace et en matériaux du logement de l~ensemble de l~essieu. L~embrayage élimine également le besoin d~une bielle de poussée et d~une fourchette de désembrayage, réduisant les coûts en outils et de production, ainsi qu~éliminant les questions associées au mauvais alignement du piston et de la bielle de poussée, de la rotation relative de la fourchette de désembrayage et de l~élément d~embrayage, et de basculement de la fourchette de désembrayage. L~embrayage inclut un ou plusieurs pistons disposés dans le logement de l~essieu ou un support pour le roulement d~entrée de la tige. La pression du fluide pousse les pistons contre un élément de l~embrayage provoquant un engagement sélectif entre l~élément de l~embrayage et un engrenage latéral entraîné par le différentiel interponts ou un boîtier différentiel abritant les engrenages différentiels du différentiel interponts.
