Abstract
An axle housing assembly and a method of manufacture. A friction weld may join a spindle to an arm portion of the axle housing assembly. An extension weld may encircle the arm portion. The extension weld may extend from the friction weld in a direction that may extend away from the spindle.
Claims20
An axle housing assembly comprising:
- an arm portion that extends around an axis;
- a spindle that extends around the axis and that extends from the arm portion;
- a friction weld that extends around the axis and that joins the spindle to the arm portion;
- and
- an extension weld that encircles the arm portion and that extends from the friction weld in a direction that extends away from the spindle, wherein the extension weld includes additional material added to the arm portion and does not include material of a curl that extends from the friction weld.
2 more elements
A method of making an axle housing assembly comprising:
- friction welding a spindle to an arm portion end surface of an arm portion, the arm portion end surface extending around an axis;
- removing an external curl that is generated when the spindle is friction welded to the arm portion, wherein removing the external curl includes severing the external curl from the friction weld;
- and
- providing an extension weld that encircles the arm portion after removing the external curl, wherein the extension weld extends from the friction weld in a direction that extends away from the spindle.

A method of making an axle housing assembly comprising:
- friction welding a spindle to an arm portion end surface of an arm portion, the arm portion end surface extending around an axis;
- removing an external curl that is generated when the spindle is friction welded to the arm portion;
- and
- providing an extension weld that encircles the arm portion after removing the external curl, wherein the extension weld extends from the friction weld in a direction that extends away from the spindle, wherein the friction weld protrudes from the spindle and from the arm portion after removing the external curl and wherein removing the external curl creates a ring surface that extends continuously around the axis such that the ring surface is disposed further from the axis than the spindle and an adjacent portion of the arm portion.
