FIELD: transport engineering; light snow-and-marsh vehicles on wide-section low-pressure pneumatic tubeless tyres. SUBSTANCE: wheel has pneumatic tubeless tyre, whose beads 2 have symmetrically arranged taper seat surfaces 3. Tyre is mounted on rim 4 provided with taper seat flanges 6 whose angles are pointed outwards from wheel center. Flanges 6 are made integral with seat rings 7 to which side rings 9 are connected by bolt joints 8. To provide reliable fitting of low and superlow pressure tyre (0.005-0.04 MPa), angle "A" between rim seat flange and tyre bead seat surface is made within 145 and 174 degrees. EFFECT: improved reliability of mounting tyre beads on rim, provision of presealing of wheel and its reliable operation at low and superlow air pressure and heavy deformations of tyres. 2 dwg |
