Title: Improvements in or relating to suspension systems for vehicles
IPC: B60G17/044
Filed: 1956-03-29
Abstract: 792,785. Pneumatic spring suspensions. RECHERCHES ETUDES PRODUCTION R.E.P. March 29, 1956 [May 5, 1955], No. 10024/56. Class 108(3) A pneumatic spring suspension comprises a pneumatic chamber 8, the volume of which varies with the load, two series (9-12 and 21-24) of auxiliary chambers of which one (9-12) is in communication with the .chamber 8 for a given static load; whilst the other series of chambers (21-24) does not communicate with the chamber 8, and means for successively putting the chambers 21-24 into communication with the chamber 8 when the latter is reduced below a volume of reference corresponding to the static load, the chambers 9-12 remaining in communication with the chamber 8, and means whereby, when the chamber 8 increases above the volume of reference, the chambers 21-24 remain closed whilst the chambers 9-12 are closed in succession. As shown, the chamber 8 is defined by a piston 5 slidable in a cylinder 2. The load is applied to the piston 5 through a column of liquid 7 acted on by a plunger 3. In the position of the piston 5, shown, which corresponds to the static load, the chambers 9-12 are connected by respective ports 13-16 with passages 18-20 in the piston 5 leading to the chamber 8. In this position of the piston, ports 25 leading from the chambers 21-24, the axes of which are disposed at right angles to the axes of the chambers 9-12, are cut off by the piston 5. When under increase in load the piston 5 rises to decrease the volume of the chamber 8, the ports 25 are brought successively into communication with passages 18a which communicate through the piston with the chamber 8. If the piston 5 lowers from the position shown in Figs. 1 and 2 due to decrease in load, the ports 25 remain cut-off by the piston 5 and the ports 13-16 are successively cut-off by the piston 5. Additional chambers 28a, 28b, (Fig. 4) may be provided so as to come in to action when the suspension is subject to higher static loads. Radial alignment of the piston 5 is secured by means of stops 26 engaging grooves in the piston (Fig. 4). Non-return valves (Fig. 8, not shown) may be provided in each of the outlets from the auxiliary chambers so as to maintain pressure in these chambers when they are cut-off by the piston 5. In   a modified construction (Figs. 6-8. not shown), the two series of auxiliary chambers are arranged in two diametrically opposed pairs of vertically disposed chambers. The volume of the chambers 9-12 and 21-24 may be varied by adjusting the position of threaded plugs 17. Alternatively these chambers may be formed with closed ends by casting so as to avoid the need for machining. A flow restriction orifice 29 may be disposed between the plunger 3 and the piston 5. The piston 5 instead of having a purely rectilinear movement may be caused to have a spiral travel, the orifices 13-16 and 25 being positioned accordingly.
