Abstract
900,904. Air springs; maintaining road vehicles height constant. SOC. APPLICAZIONI GOMMA ANTIVIBRANTI S.p.A. Oct. 14, 1959 [Oct. 18, 1958], No. 34800/59. Classes 108(2) and 108(3). A self-levelling pneumatic suspension unit comprises two axially aligned tubular spring members 1, 3 separated by a rigid partition 2 and joined at their outer ends to sprung and unsprung members A, B and having means 9 for selectively controlling the volume of liquid in one of said members. The upper spring member 1 contains air to act as pneumatic spring and the valve means 9, which may include a delay means, is actuated by linkage 10, 11 to maintain a constant distance between the sprung and unsprung members A and B. The pneumatic spring at least is a composite rubber-metal spring having helical convex curved ridges 5, 6 provided on the inner and outer rubber surfaces of the spring, the ridges being out of phase by half a pitch axially. A helical metal spring 8 is incorporated below the inner ridge 5 of the spring. In alternative constructions the spring members 1, 3 are of different sizes and the partition 2 is dished to accommodate one of the spring members 1 and 3 partly within the other. U.S.A. Specification 2,670,201 is referred to. Reference has been directed by the Comptroller to Specifications 734,549 and 781,896.
