Abstract:
A wheel, comprising a rigid rim; a soft tire arranged on said rigid rim; and means for generating different pressures from inside in said soft tire in contact zone of tire with road surface, at opposite sides of a vertical transverse plane of symmetry of said rim so as to cause pushing of said tire with rim of wheel along a roadway, said tire being subdivided in a plurality of separate chambers filled with a medium and spaced from one another in a circumferential direction, said means for generating different pressures being operative for generating a greater additional pressure in the contact zone behind the vertical transverse plane of symmetry of said rim, said means being formed so that when a speed of vehicle increases said means producing a pulse for generating different pressure in a chamber before the latter touches the ground.
