A RAIL VEHICLE WHEEL, AND A CORRESPONDING RAIL VEHICLE BOGEY

摘要

A rail vehicle wheel (2) for use on a rail presenting an angle of inclination of 1/20, includes a peripheral tread (6) comprising a running zone (8) for coming into contact with the rail, the running zone presenting in cross-section, a straight segment (8A). A rail vehicle wheel for use on a rail presenting an angle of inclination of 1/20, includes a peripheral tread comprising a running zone for coming into contact with the rail, the running zone presenting in cross-section, a straight segment; a lateral flange (12) projecting radially outwards from the tread; and a link portion (14) connecting the straight segment to the flange via a point of inflection, the link portion presenting conicity, which increases continuously going towards the flange, where the conicity (D 2-D 1/L) of the straight segment lies in 0.052-0.058. An independent claim is also included for a rail vehicle bogey comprising a frame, and wheels mounted on axles, and supporting the frame.
