Abstract
A composite torque transfer body and spline assembly includes a torque transfer component made of a first material and having a central body portion and a peripheral torque transfer portion integrally attached to and extending about the central body portion, a spline component made of a second material different from and having stiffness greater than that of the first material of the torque transfer component and also having an elongated tubular spline portion and a collar portion integrally attached to and extending about and radially outward from an end of the spline portion, and a plurality of elements on the central body portion of the torque transfer component and the collar portion of the spline component providing separate press-fitting and securing of the components to one another such that the components are mated and rotatable together about a central axis.
