  • Two speed final drive gear box
    Patent number: 4431073
    Abstract: A ground vehicle final drive system includes a hydraulic motor powered by an engine driven pump, and a planetary gear final drive unit mounted between the frame of the vehicle and the wheel hub. A two-speed gear box is mechanically coupled between the hydraulic motor and the final drive unit and includes a remotely operable hydraulic shifter which can shift the two-speed gear box between two gear ratios by the use of a coupling that is splined to the output shaft and slides between an annular recess in one output gear and onto a spline connection on the other output gear.
