A compound differential planetary gear assembly (50) includes a sun gear (52), a plurality of planet gears (53) engaging the sun gear, a plurality of first ring gears (54), and a plurality of second ring gears (55). Each of the second ring gears has a number of teeth that is different from the number of teeth of the first ring gears. The first and second ring gears are arranged alternately in an axial stack. Each planet gear has a constant gear-tooth cross-section along the length of the stack, with its gear teeth in meshing engagement with the teeth of the first and second ring gears. Loads transmitted between the first and second ring gears and the planets act in alternate directions along the length of the stack.
Un train d'engrenages planétaires différentiels composé (50) comprend un planétaire (52), plusieurs satellites (53) qui engagent le planétaire, plusieurs couronnes primaires (54) et plusieurs couronnes secondaires (55). Chaque couronne secondaire comporte un nombre de dents qui diffère du nombre de dents des couronnes primaires. Les couronnes primaires et secondaires sont disposées en séries alternées dans une pile axiale. Chaque satellite comporte une partie constante de dents transversales le long de la pile, ses dents s'engrenant avec celles des couronnes primaires et secondaires. Les charges transmises entre les couronnes primaires et secondaires et les satellites agissent en directions alternées le long de la pile.
