SUSPENSION FOR A TRACTOR-SCRAPER

摘要

A suspension for a scraper-tractor. The tractor has an axle housing which is supported on a frame by hydraulic cylinders connected to a hydraulic circuit that includes a gas-filled accumulator to provide cushioning of the frame with respect to the axle housing. A pair of longitudinal arms are connected at one end by ball joints to the frame. At their other ends, the arms are connected by vertical pivot pins to the axle housing. A transverse track bar is connected between the frame and the housing.
