Power transfer device for automotive vehicles

摘要

In a power transfer device including an input shaft rotatably mounted within a housing, a first output shaft rotatably supported on the housing for connecting the input shaft to a pair of front wheel drive axles, and a second output shaft arranged in parallel with the first output shaft and rotatably supported on the housing for drive connection to a pair of rear wheel drive axles, a shift mechanism includes a sleeve member axially slidable on the first output shaft between respective positions in which it effects a drive connection or disconnection between the output shafts, a shift rod arranged in parallel with the output shafts and axially movably supported on the housing, a shift fork mounted on the shift rod and coupled with the sleeve member, an operation rod extending through the peripheral wall of the housing and rotatably supported therethrough, the operation rod having an outer end operatively connected to a manual operation lever, and a swing arm secured to the inner end of the operation rod for rotation therewith and engaged at one end portion thereof with a recessed portion formed on the shift rod to restrict axial movement of the operation rod outwardly with respect to the housing and to restrict rotation of the shift rod.
