Apparatus for selecting a power transmission system of a four-wheel drive motor vehicle
This patent describes an apparatus for selecting a power transmission system for a four-wheel drive motor vehicle having a main transmission and a sub-transmission operatively connected to an input shaft of the main transmission, the latter transmitting its output to main drive wheels of the vehicle. The sub-transmission includes reduction gear trains and a manual clutch means manually operable to select transmitting speeds for transmitting output of an engine to the input shaft, and a transfer device for further transmitting the output of the transmission to auxiliary drive wheels of the vehicle, the transfer device comprising a manual transfer clutch. The improvement described here comprises: shaft means for shifting the clutch means in the sub-transmission; a case; an actuating rail disposed in co-axial relation to the shaft means and axially slidably engaged with the shaft means and slidably supported in the case; a rod operatively connected to the actuating rail; a fixed rail secured to the case and disposed in parallel with the actuating rail; a shift fork slidably mounted on the actuating rail and the fixed rail, the shift fork being operatively connected to the manual transfer clutch; an arm slidably engaged with the actuating rail and the fixed rail and integral with the shaft means; a manually operable select lever operatively connected the actuating rail through the rod for moving the actuating rail in first and second moving ranges respectively; and the actuating rail and the rod being substantially in alignment with each other.
