Abstract: A drive shaft includes an extruded internal tube having teeth formed thereon. The drive shaft also includes an extruded external tube having teeth formed therein and coaxially receiving the internal tube. The teeth of the internal tube engaging the teeth of the external tube, wherein the internal tube and the external tube are aluminum.

Abstract: A constant velocity joint includes an outer joint portion with a first longitudinal axis, a first attaching end, an aperture end and outer ball tracks on an inner circumferential surface, an inner joint portion with a second longitudinal axis, a second attaching end, an inner face facing towards the outer joint portion and inner ball tracks on its outer circumferential surface, balls for torque transmission between the outer and inner joint portions, an annular ball cage between the outer and inner joint portions with several cage windows in which the balls are guided. The inner and outer joint portions are arranged so that one outer ball track and one inner ball track are in each case arranged opposite to each other to form three different types of track pairs to receive one respective balls. The balls have different controlling behaviors due to different track geometries.

Abstract: An outer joint member for a joint assembly configured to receive an inner joint includes a wall forming a hollow chamber having a closed end and an open end. A plurality of restrictors are coupled to the hollow chamber each having a portion thereof extending outwardly from the inner surface of the wall of the hollow chamber. The plurality of restrictors extending from the inner surface of the wall proximate the open end of the hollow chamber.
