ABSTRACT:
A self-propelled vibratory compactor has a one-piece frame supported at one end by a steel roller drum and at the other end by a yoke-mounted, single, high-flotation pneumatic rubber tire. An engine on the frame drives hydraulic pumps which supply fluid to a hydraulic vibrator motor which drives an eccentric shaft within the roller drum, a hydraulic wheel motor which drives the pneumatic tire, and a hydraulic power steering system for turning the yoke. The yoke spindle mounts a rotary seal which transmits fluid between a pump on the frame and the wheel motor on the yoke. A special clamp-type drive wheel assembly mounted the pneumatic tire to resist slippage of the tire on the wheel assembly.
