Title (EN) LOCKING DIFFERENTIAL
(FR) DIFFERENTIEL BLOCABLE
Abstract:
(EN) A locking differential (24) is provided for selectably locking a first axle (40a) to a second axle (40b). The locking differential (24) utilizes a dog clutch assembly (90) characterized by two interlocking clutch members (92a, 92b) positioned between the differential side gears (89a, 89b) on opposing sides of the differential pinion shaft (107). The interlocking clutch members (92a, 92b) have face splines theron for engaging corresponding face splines formed on the side gears (89a, 89b). An actuating mechanism (148) can be selectably activated to force the two interlocking clutch members (92a, 92b) into engagement with the side gears (89a, 89b).
(FR) Cette invention concerne un différentiel blocable (24) permettant de bloquer de manière sélective un premier essieu (40a) à un second essieu (40b). Ce différentiel blocable (24) fait appel à un système de crabotage (90) caractérisé par le fait que deux éléments d'embrayage mutuellement blocables (92a, 92b) sont situés entre les planétaires de différentiel (89a, 89b) sur les côtés opposés de l'axe du satellite du différentiel (107). Les éléments d'embrayage mutuellement blocables (92a, 92b) comportent des cannelures faciales entrant en contact avec les cannelures faciales correspondantes formées sur les planétaires (89a, 89b). Un mécanisme d'actionnement (148) peut être activé de manière sélective afin de forcer les deux éléments d'embrayage mutuellement blocables (92a, 92b) à entrer en contact avec les planétaires (89a, 89b).
