The present invention relates to a trailing truck having a traction motor which uses a direct driving method and has a housing structure made of carbon fibers. The trailing truck includes: a stator fixed to the trailing truck; a rotor which includes a permanent magnet and is coupled to an axle; a frame surrounding the stator and the rotor; and the housing which is coupled to both ends of the frame and is made of carbon fibers in order to reduce the weight, reduce the initiatives, enhance the response properties, smooth a flux path structure, and enhance the heat emission performance. The trailing truck provides best conditions for a coupling form of a ventilation structure of the rotor and the axle. Such stable coupling form structure between the rotor structure and the housing and the reduced weight can be critical to accident prevention and cooling properties of the traction motor. The housing of the traction motor is made of carbon fibers to reduce the overall weight of the traction motor and increase the response speed.

    본 발명은 대차에 고정되는 고정자; 영구자석을 포함하고 차축과 결합되는 회전자; 상기 고정자와 회전자를 감싸는 프레임; 상기 프레임의 양단에서 결합되고, 중량 감소, 이니셔 감소, 응답 특성 개선, 자로(flux path)구조 원활, 열방출 개선 되도록 탄소섬유를 재료로 하는 하우징;을 포함하여 구성되는 것을 특징으로 하는 탄소섬유로 구성된 하우징 구조의 직결구동방식 견인전동기를 구비한 대차를 제공한다. 회전자의 통풍구조 및 차축과의 결합 형태를 최적의 조건으로 구성하기 위한 적절한 방법이며, 상기한 바와 같이 회전자의 구조와 하우징과의 안정된 결합 형태 구조 및 경량화는 안전사고 방지 및 견인전동기의 냉각 특성에서 매우 중요하고, 이와 관련되어 견인전동기의 하우징의 재료를 탄소섬유로 구성하여 견인전동기 전체의 중량을 감소시키고 또한 응답속도가 개선되는 효과가 있다.
