Abstract
A transmission assembly in accordance with the invention includes a plurality of torque-transmitting mechanisms. A hub member of the assembly includes a radially extending wall, and a circumferentially extending wall formed integrally with the radially extending wall. The circumferentially extending wall includes a first plurality of internal splines, a second plurality of external splines spaced with the internal splines, and a cylindrical end portion at a distal end of the hub and terminating both the internal splines and the external splines to prevent failure in high speed operations. A plurality of clutch plates associated with one of the plurality of torque-transmitting mechanisms are splined to the external splines of the hub member, and a plurality of clutch plates associated with another one of the plurality of torque-transmitting mechanisms are splined to the internal splines of the hub member.
