[Classes 103 (vi) and 108 (ii)] [See also Group XXXIV] In spring suspensions for road and rail vehicles of the kind in which an annular air chamber is arranged between the wheel axle and the frame or between the axle and the wheel rim and in which a disc guide plate within the air chamber is guided by lateral guide members in a plane perpendicular to the axle means exterior to the air chamber are provided for adjusting the guide members axially. Fig. 1 shows a wheel with an annular chamber arranged between the hub 3 and the rim 1, a high-pressure tyre 2 being provided. The chamber comprises single walls 4 arranged in two parts of which the inner edges 11 are clamped to the hub and the outer edges 12 to the rim 1 by means of a two-part-clamping ring 7, 8 a circular disc guide plate 6 also being clamped between the outer edges 12. The inner edges 11 are clamped between flange rings 14, 15 the ring 14 being secured by screws 13 and the rmg 15 on the inner side of the wheel being carried by a bush 16 adapted to be secured to the hub 3 by a screwed ring 31. To guide the guide plate 6 vertically the latter is engaged on each face by guides comprising graphite segment rings 17 carried by brackets 19 with the interposition of a rubber or metal spring. The brackets 19 are secured to the flange rings 15 by bolts and one of the brackets can be adjusted axially of the wheel by means of the screwed ring nut 31. Secured to the hub 3 and to the bush 16 are the ends of several cables 22 which pass through apertures 23 adjacent the outer periphery of the guide plate 6 and are designed to take the driving and braking torques and so prevent undue stress on the walls 4 of the air chamber. A rubber buffer 26 is arranged as shown to take the impact of the plate 6 when undue shock is imparted to the wheel. Air inlet valves are arranged at 37 and the walls 4 and bush 16 are provided at their joints with rubber packings to prevent air leakage. In the modification shown in Fig. 3, the air chamber is applied to the wheel axle 40 and bears directly on the undercarriage. In this case the air chamber walls 4 are provided with inner rubber tubes 41 providing in effect two chambers with a guide plate 6 arranged between them, the outer part of the guide plate 6 being integral with or secured to the undercarriage frame members. In this case also the cables 22 are dispensed with the walls of the chamber taking the torque stresses.
