PROBLEM TO BE SOLVED: To provide a cooling device capable of cooling a brake gear accommodated in a wheel irrespective of a traveling direction and maintaining braking performance, a traveling carriage including the cooling device, and a vehicle including the cooling device.SOLUTION: A cooling device includes a cooling fin 96 that is provided in a wheel 29 of a traveling wheel 13 having a brake gear 17 provided therein and rotating integrally with an axle 12, and that generates an airflow AR passing through the brake gear 17 via a ventilation hole communicating inside and outside of the wheel 29 with each other by rotation of the wheel 29 in both forward and reverse directions, the cooling fin 96 generating the airflow AR via a plurality of decorative holes 83 formed on a circumference of the wheel 29 about a rotational axis O of the axle 12.
【課題】走行方向に関わらずホイールに収容されたブレーキ装置の冷却を行って、ブレーキ性能を維持できる冷却装置、及びこれを備えた走行台車、車両を提供する。【解決手段】内側にブレーキ装置17が配されて車軸12と一体に回転する走行輪13のホイール29に設けられ、ホイール29の正逆両方向への回転によってホイール29の内外を連通する通風孔を通じてブレーキ装置17を通過する気流ARを生じさせる冷却フィン96を備え、冷却フィン96は、上記通風孔として、ホイール29に車軸12の回転軸線Oを中心とした円周上に複数形成された飾り孔83を通じて気流ARを生じさせる。【選択図】図2
