Abstract[English]
A differential assembly includes helical pinions and side gears with helical gear faces. In certain cases, the helical pinions and side gears are pre-mounted to a cage and then inserted into a case of the differential assembly as a unit. In certain cases, an electronic locking arrangement is mounted to the differential assembly. The locking arrangement includes a lock plate biased away from a lock gear. Pins extend through a case of the differential assembly to actuate the lock plate upon energization of an electric coil.[French]
Un ensemble différentiel comprend des pignons hélicoïdaux et des engrenages latéraux avec des faces d'engrenage hélicoïdales. Dans certains cas, les pignons hélicoïdaux et les engrenages latéraux sont pré-montés sur une cage puis insérés dans un boîtier de l'ensemble différentiel en tant qu'unité. Dans certains cas, un agencement de verrouillage électronique est monté sur l'ensemble différentiel. L'agencement de verrouillage comprend une plaque de verrouillage sollicitée à l'opposé d'un engrenage de verrouillage. Des broches s'étendent à travers un boîtier de l'ensemble différentiel pour actionner la plaque de verrouillage lors de l'excitation d'une bobine électrique.
