摘要： An air-cooling system for electric traction motors of a bogie of a motorized railway vehicle is shown which tends to reduce problems in drawing air through a cooling air channel to the traction motors and helps to reduce the problems encountered by the failure of a cooling fan for such electric traction motors. The air-cooling system is adapted for use with at least two air-cooled electric traction motors where each motor is coupled to an axle of a truck, the system comprising a common cooling air channel in communication with each traction motor and at least two intake channels communicating with the common cooling air channel, each intake channel including an air intake, a separately driven fan and valve means for preventing air from flowing out the intake upon failure of a fan to operate properly.
