ABSTRACT:
A road-finishing machine provided with a level-compensation arrangement. A directional wheel installed on each side of a frame includes an axle to which a vertical pin is attached. The pin is slidably and rotatably accomodated with a cylinder housing having a hydraulic fluid-filled chamber therein into which the top of the pin, shaped like a piston head, is placed. Veertical motion of the wheel and corresponding motion of the pin cause hydraulic fluid to be expelled from or drawn into the chamber. The chambers of the wheels on opposite sides of the frame are in communication with each other. Consequently, as one wheel rises, the other is forced downward by the compensating hydraulic fluid, and vice-versa, to attain a level compensation effect.
