Propshaft assembly having yoke friction welded to propshaft tube
A propshaft assembly that includes a propshaft tube and a weld yoke. The propshaft tube has a wall member. The weld yoke has a yoke body with an annular outer surface and an annular inner surface. The propshaft tube is welded to the yoke body such that a portion of the propshaft tube is disposed radially between the annular outer and inner surfaces and embedded into an axial end of the yoke body.
1. A propshaft assembly comprising:
a propshaft tube, and
a weld yoke,
wherein the propshaft tube has a wall member,
wherein the weld yoke has a yoke body and a pair of arms, the yoke body having a first and second axial ends, an annular outer surface and an annular inner surface, the pair of arms extending from the second axial end of the yoke body, and
wherein the propshaft tube is welded to the yoke body such that a portion of the propshaft tube is disposed radially between the annular outer and inner surfaces and embedded into a surface on the first axial end of the yoke body.
2. The propshaft assembly of claim 1 , wherein the propshaft tube has an inner circumferential surface and an outer circumferential surface, and wherein a portion of the weld yoke that is bonded to the propshaft tube surrounds both the inner circumferential surface and the outer circumferential surface of the propshaft tube at a location that is spaced apart from the surface on the first axial end of the yoke body.
3. The propshaft assembly of claim 1 , wherein the propshaft tube is formed of aluminum.
4. The propshaft assembly of claim 1 , wherein the propshaft tube is formed of steel.
5. The propshaft assembly of claim 1 , wherein the propshaft tube is formed of seamless tubing.
6. The propshaft assembly of claim 1 , wherein the propshaft tube is formed of welded tubing.
7. The propshaft assembly of claim 1 , wherein the wall member of the propshaft tube has a thickness of about 0.075 inch to about 0.120 inch.
8. A propshaft assembly comprising:
a propshaft tube, and
a weld yoke,
wherein the propshaft tube has a wall member with an inner circumferential surface and an outer circumferential surface,
wherein the weld yoke has a yoke body with an annular outer surface, an annular inner surface and a circumferentially extending groove disposed in an axial end face of the weld yoke between the annular outer and inner surfaces, and
wherein the propshaft tube is welded to the yoke body such that the portions of the annular outer and inner circumferential surfaces of the propshaft tube that are received in the circumferentially extending groove are bonded by the weld to the weld yoke.
