  • Wheel drive transmission unit
    Patent number: 9950562
    Abstract: Structural arrangements of wheel drive components facilitate the use of robust main roller bearings that are widely spaced apart from one another. This wide spacing minimizes the torque borne by the bearings for a given external load, because at least one bearing is placed closer to the expected load application point (e.g., the center of gravity of the wheel attached to the wheel hub of the drive unit). The present wheel drive bearings can support a heavy external load without expanding the overall size and configuration of a given wheel drive application.
    Type: Grant

    Date of Patent: April 24, 2018
    Assignee: Auburn Gear, Inc.
