Title (EN) HYDRAULIC CONTROL UNIT FOR LIMITED SLIP DIFFERENTIAL
(FR) UNITÉ DE COMMANDE HYDRAULIQUE POUR DIFFÉRENTIEL À GLISSEMENT LIMITÉ
Abstract:
(EN) A hydraulic control unit that delivers hydraulic fluid to a limited slip differential includes a hydraulic control unit housing, a motor and a pump. The hydraulic control unit housing has a manifold housing portion and an accumulator housing portion. The manifold housing portion defines a fluid pathway arrangement for communicating fluid along at least a first fluid pathway. The accumulator housing portion houses an accumulator assembly having a biasing assembly and a piston. The accumulator housing portion and manifold housing portion cooperate to form an accumulator chamber that houses the biasing assembly. The motor is disposed on the first side of the manifold housing portion. The pump is disposed on a second side of the manifold portion, opposite the first side. The pump is configured to pump fluid into the accumulator chamber of the accumulator housing portion.
(FR) La présente invention concerne une unité de commande hydraulique qui délivre un fluide hydraulique à un différentiel à glissement limité, comprenant un boîtier d'unité de commande hydraulique, un moteur et un moteur. Le boîtier d'unité de commande hydraulique comporte une partie de logement de collecteur et une partie de logement d'accumulateur. La partie de logement de collecteur définit un agencement de trajet de fluide pour communiquer un fluide le long d'au moins un premier trajet de fluide. La partie de boîtier d'accumulateur loge un ensemble accumulateur présentant un ensemble de sollicitation et un piston. La partie de logement d'accumulateur et la partie de logement de collecteur coopèrent pour former une chambre d'accumulateur qui loge l'ensemble de sollicitation. Le moteur est disposé sur le premier côté de la partie de logement de collecteur. La pompe est disposée sur un second côté de la partie de collecteur, opposé au premier côté. La pompe est configurée pour pomper du fluide jusque dans une chambre d'accumulateur de la partie de boîtier d'accumulateur.
