A control apparatus of a transfer mechanism includes a case member, an input axle, an intermediate axle arranged parallel with the input axle, an output axle on the rear wheel side arranged parallel with the input axle and the intermediate axle, an output axle on the front wheel side coaxially arranged with the output axle on the rear wheel side, an input gear mounted on the input axle, a fixing member secured to the case member, an intermediate gear mounted on the intermediate axle and engaged with the input gear, an output gear coaxially arranged with the output axle of the front wheel axle and engaged with the intermediate gear, a simple planetary gear set including a carrier integrally connected to the output gear, a ring gear integrally connected to the output axle of rear wheel side, and a sun gear selectively engaged with the output axle on the front wheel side or the fixing member or the output axle on the front wheel side and the output gear, the mechanism further including a tubular axle integrally provided with the sun gear, a first sleeve always engaged with the tubular axle and selectively engageable with the fixing member or the output axle of front wheel side, and a second sleeve always engaged with the tubular axle and followed to the sliding movement of the first sleeve.

Control apparatus of a transfer mechanism

A wheel hub clutching mechanism includes an internally splined body, and a clutch ring which is adapted to be meshed with a shaft driven pinion and is resiliently connected by means of a connecting spring to a follower which, in turn, is controlled by means of a rotatable cam. The follower and the clutch ring are biased toward the locked positions thereof by means of a compression spring when the cam is rotated to its locked position by means of a manually operated handle, and the clutch ring is retracted to the free position thereof together with the follower when the cam is rotated to its free position by means of the handle. A pinion supporting member is also interposed between the shaft driven pinion and the body, the splines of the body being formed so as to be substantially parallel to the shaft axis.
