Patent number: 9453570Abstract: A differential lock mechanism includes a shift member and a shift collar that is moveable by the shift member between an engaged position with a differential assembly and a disengaged position. A pneumatic control provides a first pneumatic signal to move the shift collar into the engaged position and provides a second pneumatic signal to return the shift collar to the disengaged position.Type: GrantFiled: December 7, 2009Date of Patent: September 27, 2016Assignee: ArvinMeritor Technology, LLCInventor: Robert J. Martin, III

Patent number: 9074677Abstract: A carrier assembly includes an adjustment member with a threaded attachment surface that is threadably attached to a mating threaded surface of a housing. The threaded attachment surface is formed on the adjustment member between first and second pilot surfaces, which allows the adjustment member to be selectively rotated to adjust a position of the adjustment member relative to the housing to set a desired carrier characteristic without requiring shims or spacers. The adjustment member also includes a splined outer surface that engages a splined lock member to lock the adjustment member to the housing once the desired carrier characteristic has been set.Type: GrantFiled: March 14, 2011Date of Patent: July 7, 2015Assignee: ArvinMeritor Technology, LLCInventor: Robert J. Martin, III

Patent number: 8579754Abstract: A locking mechanism for a differential assembly includes an adjusting ring and a retainer. The adjusting ring is rotatable about an axis and has an inner peripheral surface and an outer peripheral surface. The adjusting ring is adjustable to set a desired preload. A plurality of pockets is formed within the outer peripheral surface, and the pockets are circumferentially spaced apart from each other about the axis. The retainer has a portion that at least partially extends into one of the pockets to prevent rotation of the adjusting ring about the axis once the desired preload is achieved.Type: GrantFiled: July 28, 2011Date of Patent: November 12, 2013Assignee: Arvinmeritor Technology, LLCInventor: Robert J.

Patent number: 8579088Abstract: A drain plug for a carrier assembly is used to control fluid flow from a reservoir to a sump. The carrier assembly includes a carrier housing with an internal cavity that houses a gear assembly. The sump is located within the internal cavity to lubricate the gear assembly. The reservoir is separated from the sump by a channel. The drain plug is attached to the carrier housing, and extends into the channel, to provide a fluid flow restriction between the reservoir and the sump.Type: GrantFiled: July 25, 2007Date of Patent: November 12, 2013Assignee: Arvinmeritor Technology, LLCInventors: Robert J.

Patent number: 8469460Abstract: A spindle nut assembly includes inner and outer nuts having corresponding beveled surfaces. The inner nut is tightly threaded onto an end of a spindle and is positioned to achieve a desired endplay setting. The outer nut contacts the inner nut at an oblique angle via the beveled surfaces, which squeezes the inner nut more tightly onto the spindle while still maintaining the desired endplay setting.Type: GrantFiled: June 29, 2010Date of Patent: June 25, 2013Assignee: Arvinmeritor Technology, LLCInventors: Robert J.

Patent number: 8152674Abstract: A carrier assembly includes an auxiliary lubrication pump that lubricates gear components positioned within an internal cavity of a carrier housing. A differential gear assembly is positioned within the internal cavity to rotate about an axis. The auxiliary lubrication pump includes a first gear that is driven by the differential gear assembly about the axis and a second gear that is driven by the first gear. The first and second gears of the auxiliary lubrication pump cooperate to direct and control lubrication with the carrier housing.Type: GrantFiled: August 15, 2008Date of Patent: April 10, 2012Assignee: ArvinMeritor Technology, LLCInventors: Brian D.

Patent number: 7866433Abstract: A carrier assembly has a unique architecture which allows the carrier assembly to be defined by a very small packaging envelope. The carrier includes a main carrier housing with an internal cavity for receiving a differential and a carrier cover that closes the internal cavity once the differential has been installed. Examples of architectural features include a differential lock actuator that is mounted to the carrier cover, dowel pins that accommodate differential leg thrust loads and align the carrier cover relative to the main carrier housing, and bolt-in differential leg structures to facilitate pinion installation. Further, the carrier assembly can be utilized with an independent suspension to provide a increased jounce travel range.Type: GrantFiled: July 25, 2007Date of Patent: January 11, 2011Assignee: ArvinMeritor Technology, LLCInventors: Robert J.

Patent number: 6823970Abstract: A brake assembly is provided including a hub assembly having a barrel portion and a flange extending radially outwardly from the barrel portion. The flange includes an outer circumference, and a plurality of studs are arranged circumferentially about the flange inboard of the outer circumference. A brake drum includes a generally annular mounting portion includes a plurality of mounting holes spaced circumferentially thereabout with the plurality of studs disposed within the plurality of mounting holes. A brake drum pilot surface engages the outer circumference of the hub flange and includes a plurality of relief pockets aligned with the plurality of studs. The studs generate a deformed area in the outer circumference of the hub flange aligned with the stud. The deformed areas are received in the relief pockets so that deformation of the outer circumference of the hub flange does not interfere with properly piloting of the brake drum onto the hub assembly.Type: GrantFiled: April 17, 2003Date of Patent: November 30, 2004Assignee: ArvinMeritor Technology, LLCInventors: Brian D.

Patent number: 6698557Abstract: A brake drum assembly includes an impeller and stator that help cool the brake drum. The impeller and stator combination are especially suited for low-speed vehicle operations. The impeller includes a plurality of impeller vanes formed about the circumference of the impeller that draw cooling air across the brake drum. The impeller is mounted to an external surface of the brake drum for rotation with the drum about an axis of rotation. The stator is held fixed with respect to the drum and includes a first portion that forms a circular band, which is positioned in an overlapping relationship to the impeller, and a second portion that is transverse to the first portion. The second portion extends radially inwardly toward the axis of rotation to form a vertical face. A plurality of stator vanes are formed within the vertical face that direct the airflow away from the brake drum toward an inboard direction that is generally parallel to the axis of rotation.Type: GrantFiled: August 27, 2002Date of Patent: March 2, 2004Assignee: ArvinMeritor Technology, LLCInventors: Brian D.
