FIELD: machine building. ^ SUBSTANCE: invention relates to transportation equipment, particularly to air low-pressure tire. Wheel propeller consists of wide-section low-pressure tires, forming to protector 3 and sidewalls 2 and reference axis 5 of transport vehicle framework, sealed cavity 4, in which on reference axis 5, there are installed internal side rings 6. According to the first version track is connected to it by flexible, coinciding in frontal plane and radial plane, bracing 7. According to the second version internal cavity of tire is divided by flexible partitions on several adjacent cavities. One of sides of elastic flexible partitions is implemented in block with inner cavity of track, and the second by means of internal bead ring it is fixed to reference axis of vehicle framework. Between bead ring of sidewalls and internal bead rings there are installed distance bushings. According to the third version inside the sealed cavity, on axis of vehicle framework, with a clearance to inner surface of wide cross-section tire, it is installed hollow drum, and cavity between drum and tire is partly filled by liquid. ^ EFFECT: design simplification of propeller and also improvement of its operating characteristics. ^ 3 cl, 6 dwg |
