Said disk is arranged so that central line (7) of the disk radial section is displaced along wheel axis (9) relative to central line (8) of the disk radial section towards outer curvilinear surface (6). Amount of aforesaid displacement varies from 2 to 10 mm, while the distance between central line (8) and point (10) of maximum curvature of inner curvilinear surface (5) of disk (4) makes about 4 mm towards inner curvilinear surface.
