Title (EN) DIFFERENTIAL ASSEMBLY WITH TWO-PIECE CARRIER AND WELDED RING GEAR
(FR) ENSEMBLE DIFFÉRENTIEL AVEC CARTER EN DEUX PARTIES ET COURONNE DENTÉE SOUDÉE
Abstract:
(EN) A differential assembly is provided to include a two-piece differential carrier, a differential gearset installed within a gearset chamber formed in the differential carrier, and a ring gear. An interlocking feature mechanically interconnects the ring gear to the first and second case members of the two-piece differential carrier and defines first and second weldment junctions. A first weld seam is located in the first weldment junction and connects the ring gear to the first case member while a second weld seam is located in the second weldment junction and connects the ring gear to the second case member,
(FR) La présente invention concerne un ensemble différentiel qui comporte un carter de différentiel en deux parties, un engrenage différentiel installé à l'intérieur d'une chambre de train d'engrenages formée dans le carter de différentiel, et une couronne dentée. Un élément de verrouillage interconnecte mécaniquement la couronne dentée à des premier et second éléments de boîtier du carter de différentiel en deux parties et définit des première et seconde jonctions de soudure. Un premier joint de soudure est situé dans la première jonction de soudure et relie la couronne dentée au premier élément de boîtier, tandis qu'un second joint de soudure est situé dans la seconde jonction de soudure et relie la couronne dentée au second élément de boîtier.
