An improved final drive is disclosed. The axle includes a double reduction gearbox for off-road machines, which, unlike currently available double reduction gearboxes, contains no planetary gear sets. The improved drive axle contains spur gears having pockets adapted to contain brake disc packs. The pockets may permit utilization of a plurality of brake packs within the gearbox without requiring additional space or enlargement of the gearbox housing. Use of spur gears may thus enable use of fewer gear parts, while use of multiple brake packs may enhance final drive brake capacity, improve longevity of the brake packs, and lengthen brake servicing cycles. L'invention concerne un entraînement final amélioré. L'essieu comprend une boîte de vitesses à double réduction pour des machines hors route, qui, contrairement à des boîtes de vitesses à double réduction disponibles couramment, ne contient pas d'ensembles engrenage planétaire. L'essieu d'entraînement amélioré contient des roues droites cylindriques ayant des poches aptes à contenir des blocs de disques de frein. Les poches peuvent permettre l'utilisation d'une pluralité de blocs de frein à l'intérieur de la boîte de vitesses sans nécessiter d'espace additionnel ou d'élargissement du boîtier de boîte de vitesses. L'utilisation de roues droites cylindriques peut ainsi permettre l'utilisation de moins de pièces d'engrenage, tandis que l'utilisation de multiples blocs de frein peut améliorer une capacité de freinage d'entraînement final, améliorer la durée de vie des blocs de frein et rallonger les cycles de maintenance de frein.
