    摘要: An axle outer end is disclosed including a planetary reduction drive unit and a multiple disc friction brake. The friction brake includes a plurality of rotatable and non-rotatable discs for selectively interconnecting the ring and sun gears of the planetary drive unit. The friction brake also includes a piston for engaging and moving the discs into frictional contact with the planetary drive unit carrier to restrain rotation of the sun gear and output member. The piston is contained in a chamber formed by a portion of the planetary drive unit ring gear and a portion of an adapter secured to the outer end of a non-rotatable spindle. An improved oil circulation system is incorporated in the axle outer end to supply oil to the disc stack and permit the oil to return the main oil sump.
