VEHICLE WHEEL Russian patent published in 1998 - IPC

FIELD: transport engineering; wheels of tractors, combine harvesters, excavators and other vehicles with springless suspensions. SUBSTANCE: vehicle wheel has rim and pneumatic tyre. Elastic envelope in form of hollow torus is installed in pneumatic tyre space. Envelope divides tyre space into two spaces forming ring working space in tyre communicating with inner space of elastic envelope through valves. Center of gravity of elastic envelope is located below axis of wheel rotation. Torus truncated in its lower part rests on rim with possibility of axial rotation. Volume of inner ring working space is smaller than volume of inner elastic envelope. They are placed in communication, in addition to valves, through throttling holes. EFFECT: enlarged operating capabilities. 2 cl, 3 dwg
