WHEEL WITH CONTROLLABLE PRESSURE Russian patent published in 1994 - IPC

FIELD: aircraft industry. SUBSTANCE: wheel with controllable pressure has rim 1 mounted on axle 2, H-shaped metallic member 3 fixed on rim 1, bandage 4 set on the cheeks of H-shaped metallic member 3 and toroidal shell 5 whose interior cavity is filled with compressed air. In this case toroidal shell 5 is placed in the cavity formed by bandage 4 and the cheeks of H-shaped metallic member 3. Besides, the toroidal shell is provided with coupling 6 which is connected with the pneumatic system of a vehicle through a system of holes in H-shaped metallic member 3, rim 1, axle 2. Tyre with tread part 7 encompassing bandage 4 and leaning against its peripheral surface with the inner ring-shaped protrusion in the equatorial plane is mounted on rim 1. Bandage 4 can be made of a set of flat springs set on the cheeks of H-shaped metallic member 3 and contracted in the axial direction till the state of longitudinal curve. EFFECT: expanded range of suppressed oscillations towards low frequencies by means of securing quasi-neutral rigidity of oscillations in a wide range of loads. 2 cl, 6 dwg
