  • Direct torque path differential having spiderless pinions
    Patent number: 10082199
    Abstract: A differential is disclosed for use with a drivetrain of a mobile machine. The differential may have an input gear, a first side gear, a second side gear, and a side pinion disposed axially between and intermeshed with the first and second side gears. The differential may also have a carrier nested inside of the input gear and connected to the input gear and the side pinion. The carrier may at least partially surround the first side gear and the second side gear.

  • Direct torque path differential having spiderless pinions
    Patent number: 9797503
    Abstract: A differential is disclosed for use with a drivetrain of a mobile machine. The differential may have an input gear, a first side gear, a second side gear, and a side pinion disposed between and intermeshed with the first and second side gears. The differential may also have a carrier connected to the input gear and surrounding the first side gear, the second side gear, and the side pinion. The carrier may have a first orifice located in an annular wall at a base end of the side pinion, and a second orifice located in an axial wall. All lubrication passing through the first orifice may flow around an external surface of the side pinion.
