PLANETARY TRANSMISSION GEARING AND OUTPUT SHAFT RETENTION MEANS

摘要

A planetary gear arrangement for an automatic power transmission mechanism in an automotive driveline having rearward traction wheels and a forward engine wherein axial loads developed on the gearing due to thrust forces resulting from displacement of the rear vehicle suspension while the vehicle is accelerating or when it is operated over a rough road bed are transmitted directly to the case as the torque transmitting elements of the gearing are isolated from these thrust forces, and wherein provision is made for preloading thrust bearings in the gearing to accommodate axial displacement of the torque output shaft with respect to the other torque transmission elements of the gearing when the suspension is deflected and the geometry of the driveshaft and suspension system changes while the vehicle is operating under torque.
