[Also in Division F2] A (rail) vehicle suspension comprises an air spring 1 in the form of an open annulus having peripheral beaded edges 2, 3 of different diameters and connected in series to a rubber spring 9 or coil spring 10, the arrangement providing flexibility at right angles to the springs' axes. The capacity of the air spring may be augmented by an auxiliary chamber 12, Figs. 3 or 4. The rubber or coil springs may be replaced by a number of rubber or coil springs, respectively, acting in series. As shown in Fig. 7, one or more coil springs are connected to the air spring at its larger diameter edge, the smaller diameter edge being connected to a cylindrical member 18. The rubber spring may act in shear, as shown at 20 in Fig. 8.</p> |
