  • Apparatus for controlling a front wheel driving force for use in an all wheel drive asphalt finisher
    Patent number: 5311964
    Abstract: The right and left front wheels of an asphalt finisher are each supported by a beam, one end of which is mounted to the body of the asphalt finisher by way of a pin such that the beam can swing, and the other end of the beam is mounted to the end of the piston rod of a hydraulic cylinder which is vertically mounted to the body of the asphalt finisher in a downward direction, both cylinders being connected to each other by way of a single oil line. As a result, when either one of the front wheels encounters an obstacle, the sideward inclination of the body can be eliminated.
