  • Axle assembly having mechanism for circulating lubricating fluid to wheel ends
    Patent number: 8021258
    Abstract: An axle assembly with an axle shaft, an annular disc and a pair of change members. The axle shaft includes an unthreaded body portion having a first diameter. The annular disc is mounted on the body portion and has a central aperture through which the unthreaded body portion is received. The central aperture has a second diameter that is larger than the first diameter. Rotation of the axle shaft causes the annular disc to translate on the unthreaded body portion between the change members and wherein a direction in which the annular disc translates is changed through contact between the annular disc and the change members.
