Patent number: 10100911Abstract: A mounting system for a differential comprises a cross shaft. The cross shaft comprises a passageway through the cross shaft perpendicular to a long axis. The passageway comprises a first hole and a second hole. A recess comprising a planar wall is proximal to the first hole. A first stub shaft comprises a planar surface in contact with the planar wall. A second stub shaft is proximal the second hole. A yoke in the passageway comprises a first portion extending in to the first stub shaft and a second portion extending in to the second stub shaft. A first bang ring is on the first portion of the yoke, and a second bang ring is on the second portion of the yoke. The yoke slip fits to the first stub shaft and the yoke slip fits to the second stub shaft.Type: GrantFiled: March 26, 2016Date of Patent: October 16, 2018Assignee: Eaton Intelligent Power LimitedInventor: Daniel Philip Fisher

Patent number: 9695884Abstract: A piston system comprises a housing (3) comprising a first recess (6) and a second recess (7). A first piston (1) comprises a first portion embedded in the first recess (6). A second piston (2) comprises a second portion embedded in the second recess (7). An actuator (10) has a first side (20) and a second side (21). The first piston (1) selectively presses against the first side (20) of the actuator, and the second piston (2) selectively presses against the second side (21) of the actuator. The actuator may be a synchronizer of a clutch assembly.Type: GrantFiled: March 15, 2013Date of Patent: July 4, 2017Assignee: Eaton CorporationInventors: John Allen Grogg, Daniel Philip Fisher, Scott Michael Besemer, Gregory L.

Patent number: 9664271Abstract: A differential includes a differential case; a side gear; a pinion configured for meshing engagement with the side gear; and a pinion housing configured to support the pinion. The pinion housing includes a first face; a second face opposing the first face; a first projection located on the first face; and a second projection located on the second face. The pinion housing also includes an aperture or hole extending radially inwardly from an outer radial surface of the generally annular ring; and a channel extending from the first face to the second face, wherein the channel is substantially radially aligned with the aperture or hole. In embodiments, the pinion housing includes one or more transfer formations configured to transfer torque from the differential case, and the pinion housing is configured to permit movement in an axial direction between a pair of side gears.Type: GrantFiled: January 9, 2013Date of Patent: May 30, 2017Assignee: Eaton CorporationInventors: Paul N. Herrmann, Steven J. Cochren, Sandeep Kumar, Steven A. Rudko, Stephen P. Radzevich, Matthew G. Fox, Daniel Philip Fisher

Patent number: 9303750Abstract: A mounting system for a differential, comprising a cross shaft, a first stub shaft, a second stub shaft, and a yoke. The cross shaft comprises a long axis and a passageway through the cross shaft perpendicular to the long axis, the passageway comprising a first hole and a second hole. The first stub shaft comprises a long axis parallel to a central axis of the first hole. The second stub shaft comprises a long axis parallel to a central axis of the second hole. The yoke is in the passageway and comprises a first portion extending in to the first stub shaft and a second portion extending in to the second stub shaft.Type: GrantFiled: September 6, 2012Date of Patent: April 5, 2016Assignee: Eaton CorporationInventor: Daniel Philip Fisher

Patent number: 9080622Abstract: A hydraulic coupling for use in a vehicle drive train having a fluid path which extends between the housing of the hydraulic coupling and a coupling mechanism. The fluid path includes a first aperture formed in the housing with a first diameter and a longitudinal axis, as well as a second aperture formed in the coupling mechanism. A rigid conduit extends between the first and second apertures with a first portion having a diameter that is less than the first diameter of the first aperture so as to define an adjustment gap that allows the rigid conduit to move out of alignment with the longitudinal axis in response to misalignment between the first and second apertures. In addition, the rigid conduit provides resistance to torque imposed upon the coupling mechanism.Type: GrantFiled: April 3, 2009Date of Patent: July 14, 2015Assignee: Eaton CorporationInventors: Andrew Nathan Edler, Daniel Philip Fisher, Matthew George Fox

Patent number: 8911322Abstract: A differential, comprising a gear case, a side gear, an actuator, and a collar. The gear case comprising a central axis and recesses. The side gear configured to rotate around the central axis. The side gear comprising radially outward-extending locking members comprising side gear segments separated by plural grooves. The actuator surrounding the central axis. The collar configured to translate bi-directionally along the central axis. The collar comprising ears and radially inward-extending locking members comprising collar segments separated by plural grooves. The actuator is configured to move the collar relative to the side gear to move the ears axially in the recesses. When the actuator moves the collar to a locked position, the collar segments are configured to engage the side gear segments. When the actuator moves the collar to an unlocked position, the side gear segments are configured to pass through the grooves of the radially inward-extending locking members.Type: GrantFiled: March 15, 2013Date of Patent: December 16, 2014Assignee: Eaton CorporationInventors: Patrick John McMillan, Daniel Philip Fisher
