Patent number: 11371600Abstract: A front axle assembly with an axle housing that has first and second housing halves that each include a main housing portion, a tubular portion and a steering yoke. The main housing portion defines a cavity that houses at least a portion of a speed differentiation mechanism. The tubular portions are fixedly coupled to an associated one of the main housing portions and extend between the main housing portion and an associated one of the steering yokes. Each steering yoke is fixedly coupled to an associated tubular portion. An annular joint structure is formed where the first and second first housing halves are coupled to one another. The annular joint structure is formed about the rotary axis such that one of the first and second housing halves is inserted into the other one of the first and second housing halves along an insertion axis that is coincident with the rotary axis.Type: GrantFiled: September 25, 2018Date of Patent: June 28, 2022Assignee: American Axle & Manufacturing, Inc.Inventors: Gregory A. Marsh, Jonathan P. Prichard, Frederick E. Zink, James P. Downs, Joseph M. Endreszl

Patent number: 10160314Abstract: A vehicle with a primary driveline that is configured to distribute rotary power to a first set of vehicle wheels and a power transmitting device that can be selectively operated to transmit rotary power to a secondary driveline. The power transmitting device has an input member, which is driven by the primary driveline, and an output member that is selectively coupled to the input member to receive rotary power therefrom. The secondary driveline comprises a differential, a pair of shafts, and a side shaft coupling that selectively interrupts power transmission between the differential and one of the shafts.Type: GrantFiled: November 11, 2016Date of Patent: December 25, 2018Assignee: AMERICAN AXLE & MANUFACTURING, INC.Inventors: Gregory A. Marsh, James P. Downs, Richard S. Silbert

Patent number: 9333965Abstract: A drive train having a locking differential and a control unit for controlling operation of the locking differential. The control unit is responsive to selected vehicle characteristics to sua sponte activate or inactivate a locking mechanism of the locking differential to cause the locking differential to operate in a locked manner or an unlocked manner, respectively. A method for operating a locking differential is also provided. The method includes: utilizing only preselected vehicle criteria indicative of the operational state of the vehicle to identify a situation in which a locking mechanism associated with the locking differential is to be energized; and responsively energizing the locking mechanism.Type: GrantFiled: March 13, 2014Date of Patent: May 10, 2016Assignee: American Axle & Manufacturing, Inc.Inventors: Gregory A. Marsh, Russell T. Capito, John C. Hibbler
