Patent ID: 8251829

Claim:
Constant velocity ball joint comprising: an outer joint part including a connection side, an opening side and a cavity bounded by an inner surface first outer ball tracks and second outer ball tracks extending on the inner surface between the connection side and opening side; an inner joint part-positioned in the cavity of the outer joint part, the inner joint part including connection means for a shaft running in a direction of the opening side of the outer joint part and first inner ball tracks and second inner ball tracks extending on an outer surface of the inner joint part, at least one each of the first outer ball tracks and the first inner ball tracks form first track pairs, and at least one each of the second outer ball tracks and the second inner ball tracks form second track pairs, wherein, when the constant velocity ball joint is not articulated, the first track pairs form a first opening angle (W 1 ) in a central joint plane (E 1 ) relative to the connection side of the outer joint part, and the second track pairs form a second opening angle (W 2 ) in the central joint plane (E 1 ) relative to the opening side of the outer joint part; a ball in each track pair; and a cage arranged in the cavity between the outer joint part and the inner joint part, the cage including a plurality of cage windows, each of which receives at least one ball; wherein the first track pairs each form a first track centerline (L 1 ) that has a first inflection point (P 1 ), and the second track pairs each form a second track centerline (L 2 ) that has a path other than a circular path in a section between the central joint plane (E 1 ) and the connection side.
