Abstract
A torque transfer mechanism is disclosed for incorporation in a four-wheel drive vehicle for establishing high and low speed power paths to front and rear drive axles. The torque transfer mechanism comprises an input shaft for receiving power from an engine and a pair of output shafts for delivering power to the drive axles. Constant mesh gearing is provided to operatively connect the input and output shafts in desired power paths. The gearing comprises an input gear set and an output gear set. Each gear set includes a plurality of gears provided with clutch means adapted to be selectively engaged by a pair of clutch collars. The clutch collars can be operated simultaneously in the same axial direction by a single shift fork to drive the front and rear axles in either the high or low speed power path.
