Embodiment Construction

[0016] The embodiments of the present invention will be explained below in conjunction with the drawings.

[0017] Such as Figure 1 to Figure 4 As shown, this embodiment is used for the cooling and ventilation device of the traction motor of the urban train, which mainly includes the cooling fan 1, the air supply duct 2, the soft air duct 3 and the telescopic tube 4.

[0018] The cooling fan 1 is fixed to the hanging beam 8 through a shock absorber, and the hanging beam 8 is fixed to the side beam of the vehicle body underframe, so that the cooling fan 1 is hoisted on the vehicle body underframe.

[0019] The air outlet of the cooling fan 1 is connected to the air supply duct 2 via the soft air duct 3. The air supply duct 2 has two air outlets, respectively corresponding to the air inlets of the two traction motors of the bogie, and the air inlet of the traction motor is connected to the air outlet of the air duct 2 through a telescopic tube 4. The air supply duct realizes one inl...

Abstract

The invention relates to a traction motor cooling and ventilating device for a city region train. The device comprises a cooling fan and an air supply duct, the air inlet of a traction motor communicates with the air supply duct, the air supply duct comprises a main air duct, an upper air duct leading to a far-end traction motor and a lower air duct leading to a near-end traction motor, the lowerair duct is arranged below the upper air duct, the upstream ends of the upper air duct and the lower air duct are connected with the main air duct, and guide plates are arranged in the main air duct,the upper air duct and the lower air duct at intervals in the airflow direction and arranged along the center line of the air duct so as to reduce turbulent flow. Each traction motor cooling fan coolsthe two traction motors of the same bogie to form a one-to-two structure, and an air duct is newly designed, so that the traction motor cooling and ventilating device is particularly suitable for city region trains with narrow bottom spaces.

Description

Technical field [0001] The invention relates to a traction motor cooling and ventilation device used for urban trains, and belongs to the technical field of rail vehicle air conditioning systems. Background technique [0002] With the development of new urbanization in my country, especially the rise of metropolises and cluster cities, urban railways are showing a momentum of rapid development. At present, many cities in China are planning urban railways. Urban train technology is based on high-speed EMU technology and Type A subway vehicles and technology. When the design speed of the urban train reaches about 160km / h, the vehicle must be equipped with traction motor cooling and ventilation devices. [0003] At present, cooling and ventilation devices are often used in EMUs, but since the underframe space of EMUs is relatively abundant, there is no need to consider the limitation of installation space caused by structural problems. The commonly used air cooling method for tracti...
