Abstract
A halfshaft assembly in a vehicle is disclosed. The halfshaft assembly includes a hub and a mating universal joint, such as a constant-velocity joint. The hub has a plurality of hub-teeth arranged annularly about an axis. The constant-velocity joint has a plurality of joint-teeth arranged annularly about the axis and engaged with the hub-teeth. Between each joint-tooth is a joint-root. The top, outermost surface of each tooth facing away from adjacent roots extends at a first angle with respect to the central axis. The root extends at a second angle with respect to the central axis. The angles are different such that the height of the tooth varies along the same tooth along the length of the tooth. Each tooth has involute side surfaces. The joint-teeth form a conical or inverse-conical shape.
