Abstract

Ce différentiel possède une roue principale creuse 8 attaquée par un pignon 7 et deux planétaires 12, 13 engrenants disposés à l'intérieur de la roue 8 et reliés à des arbres de roue 3 par des joints 2. Selon l'invention, les planétaires 12, 13 constituent en même temps une pompe à engrenages, dont la paroi est formée par la roue principale 8 et qui refoule le lubrifiant normal du différentiel à travers un étranglement, ce qui crée une résistance tendant à freiner la rotation des planétaires 12, 13 l'un par rapport à l'autre.This differential has a hollow main wheel 8 driven by a pinion 7 and two sun gears 12, 13 gears arranged inside the wheel 8 and connected to the wheel shafts 3 by joints 2. According to the invention, the sun gears 12 , 13 constitute at the same time a gear pump, the wall of which is formed by the main wheel 8 and which delivers the normal lubricant of the differential through a throttle, which creates a resistance tending to slow the rotation of the planetary wheels 12, 13 l 'one in relation to the other.
