Abstract
A power transmission has axially aligned torque transmitting mechanisms. Each torque transmitting mechanism has a backing plate slidably disposed on a spline formed in the housing of the power transmission. Each backing plate has a locating ring to limit the axial movement of the backing plate and therefore the members of the torque transmitting mechanism during engagement. The locating rings are disposed in an L-shaped groove such that the outer locating ring is narrower that the inner locating ring. The backing plate of one of the torque transmitting mechanisms has an outer segmented annular extension that is aligned with the narrower locating ring to prevent interference between the backing plates when the one torque transmitting mechanism is engaging. The backing plate of the other torque transmitting mechanism is limited in axial movement by the wider locating ring which prevents contact between the backing plate and the narrow locating ring, thus preventing interference between the backing plates when the other torque transmitting mechanism is engaging.
