Drive axle assembly with lubrication systems for lubricating gears and / or differential bearings

摘要

An axle assembly (22) comprising: an axle housing (54) having an interior cavity (78), a portion of the interior cavity (78) defining a first reservoir (62), a ring gear (104) mounted in the interior cavity (78 ) is rotatably mounted about a first axis (82) and is rotatable by the first header tank (62) to cause adhesion of a lubricant (90) in the first header tank (62) to the ring gear (104), a differential connected to the ring gear (104) so as to rotate about the first axis (82), and a pinion (150) disposed in the inner cavity (78) of the axle housing (54) about a first axis (54); 82) is rotatably mounted, said pinion (150) having a plurality of teeth (150a) engaging a plurality of teeth (104a) formed on said ring gear (104) and an additional one Collecting means (200) for collecting a part of the lubricant (90), which during the rotation of the ring gear (104 ) is adhered thereto in a predetermined rotational direction by the first header tank (62), the additional header means having a second header tank (202) and a drain (206), the second header tank (202) disposed in the interior cavity (78) and is separated from the first collection container (62) and the drain (206) is configured to direct the second collection container (202) at least partially directly onto the teeth (105a) of the pinion (105) and / or the teeth (104a) of the Ring (104) emptied, wherein the drain (206) is also configured so that it delivers a portion of the lubricant (90) in the second reservoir (202) on a set of pinions (152), the pinion (150) in the axle housing (54) rotatably, the additional collecting means having a third collecting container (500) which is arranged in the inner cavity (78) and from the first and the second collecting container (62, 202) is separated, wherein the third collecting container ( 5 00) is configured to empty the lubricant (90) contained therein into a set of differential bearings (102) that rotatably support the differential about the first axis (82).
