Abstract:
1. A power transmission device for use in a four-wheel drive vehicle having a power source and first and second drivelines, the power transmission device comprising: an input shaft adapted to be driven by the power source; a first output shaft being rotatable about a first axis and adapted to transmit torque to the first driveline; a second output shaft adapted to transmit torque to the second driveline, the second output shaft being rotatable about a second axis, wherein the first and second axes diverge from one another; a transfer unit having a drive member driven by the first output shaft and a driven member driving the second output shaft, the drive member and the driven member being in a torque transferring arrangement with one another; and a spline coupling positioned within a cavity formed in the driven member and drivingly interconnecting the driven member and the second output shaft, wherein the second output shaft is axially moveable relative to the driven member and the spline coupling includes a convex curved spline formed on the second output shaft.
