FIELD: transport.SUBSTANCE: invention relates to wheel disc setting surface, mainly, of agricultural or construction machinery. Wheel comprises rim for tire to seat thereat. Said rim axial inner and outer parts and medium part located there between. Every said axial inner and outer part form flange 22, connection surface 23 connected with flange 22 to extend axially toward medium part 18. Flange 22 and portion of connection surface 23 make a seat for tire bead. Connection surface 23 shaped to truncated cone at its larger-radius axial end with is connected with flange 22 while minimum-radius axial end is connected with concave surface 26 extending along the circle. Said concave surface extends radially outward along wheel axes behind the minimum-radius end connected with aforesaid connection surface 23 shaped to truncated cone.EFFECT: longer life, decreased weight and lower costs.25 cl, 4 dwg |
