Abstract

The invention discloses a rail wheel and a rail transport vehicle. The rail wheel and the rail transport vehicle are used for rail transportation. The rail gnawing phenomenon of the wheel can be reduced. The rail wheel comprises a circumferential tread and a wheel flange. The wheel flange is arranged at the edge of the circumferential tread in a surrounding mode. A guide slope surface is arranged between the side surface, adjacent to the circumferential tread, of the wheel flange and the circumferential tread and comprises a first slope surface and a second slope surface, wherein the first slope surface is connected with the circumferential tread, the second slope surface is connected with the first slope surface and the side surface of the wheel flange, and the first slope surface has fixed gradient relative to the circumferential tread.

Description

technical field [0001] The invention belongs to the technical field of rail transportation, and in particular relates to a rail wheel and a rail transportation vehicle. Background technique [0002] The part of the wheel used for rail transportation in contact with the track includes a tread and a rim, the tread is the circumferential surface of the wheel, and the rim is an annular flange located at the edge of the wheel tread and protruding from the wheel tread in the radial direction. When the vehicle is running, the tread surface of the wheel is in contact with the top surface of the track to bear the weight of the vehicle, and there is a predetermined gap between the side of the wheel rim and the side of the track. However, due to ground subsidence or track deformation, the axial deviation of the wheel may occur during operation, causing the side of the wheel rim to press against the side of the track, that is, the phenomenon of "rail gnawing". Abnormal loss of track. ...
