Patent number: 8528920Abstract: An adjustment assembly includes first and second connection points associated with a component. The second connection point is selectively adjustable to adjust a position of the component. A shield has one end coupled to the first connection point and an opposite end proximate to the second connection point to selectively prevent access to the second connection point. The shield is selectively movable when the first connection point is loosened to allow access to the second connection point. To achieve proper adjustment of the component, the first connection point must be loosened prior to adjusting a position of the second connection point.Type: GrantFiled: March 1, 2011Date of Patent: September 10, 2013Assignee: Arvinmeritor Technology, LLCInventors: Gustavo Vieira Borges, Robert J. Brazeau, Christopher J. Wittry, Michael D. Lynch, Michael A. Power, Gregory Todd Smith, Kenneth G. Lang, Anthony E. Nicol, Gregory D. Pavuk, Edward J. Gebal, Thomas S. Mijal, Esequiel Berra de Mello, Christopher S. Keeney, David G. Gonska

Patent number: 8397774Abstract: An axle assembly includes a non-rotating component and a wheel hub supported for rotation relative to the non-rotating component about an axis. The wheel hub includes a hub air passage that has a hub inlet and a hub outlet to be fluidly connected to at least one tire. An air chamber is formed at least in part between the non-rotating component and the wheel hub. The air chamber receives air flow from an air source and directs air flow into the hub inlet. A seal assembly engages the wheel hub to seal the air chamber.Type: GrantFiled: March 18, 2011Date of Patent: March 19, 2013Assignee: ArvinMeritor Technology, LLCInventors: David Gregory Gonska, Tracy Gerard Ellis, Yenkai Brian Wang, Steven Ray Miller, Jeremy Tertzakian, Scott Arthur Jenkinson, John David Morgan, Norman Austin, Christopher J.

Patent number: 7967045Abstract: A drive axle assembly includes a non-rotating spindle having a cylindrical body defining an internal cavity and an axle shaft assembly mounted within the internal cavity for rotation about an axis. A seal assembly is positioned within the internal cavity to provide a sealed chamber between the axle shaft assembly and the non-rotating spindle. A first air passage is formed within the cylindrical body and includes an air inlet to be in fluid communication with an air supply and an air outlet in fluid communication with the sealed chamber. A second air passage is formed within the axle shaft assembly and receives air input from the sealed chamber and includes an air output to be associated with at least one tire.Type: GrantFiled: March 3, 2010Date of Patent: June 28, 2011Assignee: ArvinMeritor Technology, LLCInventors: Scott Jenkinson, Jeremy Tertzakian, Steven R.
