ABSTRACT:
A bypass drive line for a torque converter type automatic transmission in which the bypass drive line includes a viscous coupling. The viscous coupling is of a sandwich construction including an annular body member, an annular cover member secured at its outer periphery to a side face of the outer peripheral portion of the body member and spaced axially from the body member to define a viscous fluid chamber therebetween, and an annular clutch member disposed in the chamber and having a central hub portion adapted to be drivingly connected to the output shaft of the torque converter. The drive into the coupling from the housing of the torque converter is through an annular clutching surface defined on the side face of the radially outer peripheral portion of the body member radially outwardly of the outer periphery of the cover member. The body member includes a central hub portion which is journaled on the central hub portion of the clutch member and the radially innerperiphery of the cover member is sealed to the clutch member in non load-bearing relation so that the entire radial and thrust loading of the body member and cover member are carried at the journal between the hub portions of both the body member and the clutch member.
