Abstract
A two-and-four-wheel drive shifting system of the type not including a differential gear unit comprises a pair of output shafts extending opposedly from each other and mounted rotatably independently of each other, an input member mounted concentrically and rotatably on one end of one of the pair of output shafts, and a sliding clutch mounted operatively on the other of the pair of output shafts. The sliding clutch having an engagement claw adapted to commonly engage with claws provided on one output shaft and on an input member in such a manner that the sliding clutch may be shifted in sliding motion in the axial direction along the other output shaft so as to selectively engage and disengage with either of the output shafts and the input member so that either the two-wheel or four-wheel drive position can be selected. A second embodiment provides a two-and-four wheel drive shifting system of the type including a differential gear unit, comprising a pair of output shafts extending opposedly from each other and mounted rotatably independently of each other, a differential gear unit disposed intermediate the pair of output shafts, an input gear mounted concentrically and rotatably o…
