Abstract

Dispositif (1) différentiel interposable entre des arbres de roues coaxiaux et le moteur d’un engin roulant, et comprenant un pignon (2), deux mécanismes d’embrayage, une enveloppe (6) logeant les mécanismes d’embrayages et définissant un passage (7) traversant de réception des arbres de roues, chaque mécanisme d’embrayage comprenant un premier élément (4) d’embrayage et un deuxième élément (5) d’embrayage rotatifs montés mobiles à rotation autour d’un axe confondu avec l’axe longitudinal du passage (7) traversant. L’enveloppe (6) affecte la forme d’un boîtier (8) comprenant un corps (9) et un couvercle (10) munis chacun d’une ouverture (91, 101) traversante, le pignon (2) est porté par le corps (9) qui comprend un fond (92) muni de l’ouverture (91) traversante dudit corps (9) et une paroi (93) latérale périphérique, le pignon (2), ou la couronne dentée, réalisé d’une seule pièce avec ledit corps (9) s’étendant au moins partiellement autour de la paroi (93) latérale périphérique dudit corps (9). Figure pour l’abrégé : Fig. 2Differential device (1) interposable between coaxial wheel shafts and the engine of a rolling machine, and comprising a pinion (2), two clutch mechanisms, an envelope (6) housing the clutch mechanisms and defining a (7) through-receiver of the wheel shafts, each clutch mechanism comprising a first rotary clutch element (4) and a second rotary clutch element (5) mounted to rotate about an axis coinciding with the longitudinal axis of the passage (7) crossing. The envelope (6) takes the form of a box (8) comprising a body (9) and a lid (10) each provided with a through opening (91, 101), the pinion (2) is carried by the body (9) which comprises a bottom (92) provided with the through opening (91) of said body (9) and a peripheral side wall (93), the pinion (2), or the ring gear, made in a single piece with said body (9) extending at least partially around the peripheral side wall (93) of said body (9).
