Abstract

1332183 Hydropneumatic suspension units TOKICO Ltd 1 Oct 1970 [9 Oct 1969] 46841/70 Heading F2S In a piston-cylinder vehicle suspension unit which has a hollow piston rod P containing gas D and liquid C, and a piston 12 dividing the cylinder into two liquid chambers A, B, the piston 12 has at least one passage 15 providing permanent communication between A and B; there are check valve means 16-21 in a direct (as shown) or indirect (Fig. 4, not shown) liquid flow path between C and B; and there is a resilient member 26 in the chamber A to buffer upward strokes of the piston 12. The boundary between chambers C and D may be a floating piston (Figs. 6, 9, not shown) or a diaphragm (Fig. 7, not shown). The lower end connection may be replaced by a stub axle (Fig. 5, not shown) and the upper connection may incorporate a device (Fig. 3, not shown) for filling the unit with liquid and gas and the subsequently adjusting the gas pressure. In Figs. 8, 9 (not shown) the unit is combined with an external helical spring. Figs. 2A-2C and 10 (not shown) are graphs of the operating characteristics of the unit.
