Universal joint yoke

摘要

A universal joint yoke having a tubular body and a pair of ears projecting generally axially therefrom is provided. The ears-have an inner surface, an outer surface and an ear connecting surface. The ear connecting surface has a pair of lower portions, a pair of transition portions and an upper portion. The lower portions are oriented such that a generally straight line drawn in the tubular body connecting surface plane goes through (i) a point at the junction of the ear outer surface and the ear connecting surface; (ii) a point at the junction of the ear inner surface and the ear connecting surface; and (iii) a point on the axis of the tubular body. The upper portion is oriented such that a generally straight line drawn between (i) a point on the junction of the ear outer surface and the ear connecting surface and (ii) a point at the junction of the ear inner surface and the ear connecting surface is generally parallel to the common axis. The universal joint yoke includes a generally concave endcap.
