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: 6802793Abstract: An arrangement for securely retaining a cross pin within a differential assembly includes a cross pin having a groove positioned proximate a recess formed in a differential housing. The recess and the groove define a retention passageway at least partially filled with molten resin. Solidified resin material positioned within the retention passageway retains the cross pin in the differential housing. Another embodiment cross pin retention system includes a pair of locking clips coupled to the cross pin. Each of the pinion gears of the differential assembly is retained between one of the locking clips and the differential housing.Type: GrantFiled: February 17, 2003Date of Patent: October 12, 2004Assignee: American Axle & Manufacturing, Inc.Inventors: Frederick E. Zink, Joseph M. Endreszl

Patent number: 6533697Abstract: A drive axle assembly for a motor vehicle includes an axle housing a differential bearing, a differential assembly, an adjustment nut and an adjuster lock. The differential assembly is rotatably supported within the axle housing by the differential bearing. The differential bearing is coupled to the axle housing via a bearing cap having an aperture formed therein The adjustment nut has at least one retention aperture and the adjustment nut is engaged with the differential bearing such that rotation of the adjustment nut axially displaces the differential bearing. The adjuster lock includes a first portion and a second portion. The first portion has a barb disposed in the bearing cap aperture. The second portion has a first lock pin disposed in the retention aperture thereby restricting the adjustment nut from rotating relative to the bearing cap.Type: GrantFiled: April 27, 2001Date of Patent: March 18, 2003Assignee: American Axle & Manufacturing, Inc.Inventors: David M. Morse, Jill R. Gnass, Joseph M. Endreszl
