Abstract
The present invention is directed to a two-speed gear reduction unit and a shift mechanism for establishing two distinct speed ratio drive connections between an input member and an output member. More specifically, the shift mechanism includes a clutch apparatus for stopping relative rotation between the input and output members prior to shifting the gear reduction unit from its neutral operating state into either of its high-range or low-range operating states. Thus, the present invention is adapted for use in the transfer case of a four-wheel drive vehicle for shifting between four-wheel high-range and low-range drive modes.
