COOLING DEVICE FOR RAILWAY WHEELS

摘要

A cooling device especially adapted to be applied to railway car wheels that are subjected to heating by the application of braking pressure to the rims. The cooling structure is suitable for mounting on existing wheels as well as on new wheels. It comprises a plurality of vanes extending radially from the hub of the wheel to its rim in spaced relationship. An annular cover is attached to the outer edges of the vanes to form a plurality of channels that have an opening at the hub end and another opening at the rim end. As the wheel rotates an air stream is formed in each of the channels with the air entering the channel at the hub opening, and exhausting at the rim opening so that the air impinges on the rim to carry away the heat from the rim.
