평행 카르단 구동 방식의 조향 대차(3)는 대차 프레임(7)과, 차량 길이 방향의 전방 및 후방에 있어서 차폭 방향을 따라 배치된 제1 및 제2 차축(9)과, 대차 프레임(7)에 대해 제1 및 제2 차축(9) 모두를 회동시켜 조향하는 조향 기구(30)와, 대차 프레임(7)에 지지된 상태에서 차량 길이 방향의 전방 및 후방에 각각 배치되어 비조향 시에 있어서 제1 및 제2 차축(9)에 평행한 제1 및 제2 출력축(28)을 각각 갖는 제1 및 제2 전동기(12)와, 제1 및 제2 차축(9)에 각각 연결된 제1 및 제2 감속기(13)와, 제1 및 제2 출력축(28)을 제1 및 제2 감속기(13)에 각각 연결하여 조향 시에 있어서의 제1 및 제2 차축(9)의 회동에 추종시키고 제1 및 제2 출력축(28)과 제1 및 제2 감속기(13)를 상대 변위시키는 제1 및 제2 등속 볼 조인트(15)를 구비한다.

    A parallel cardan driving system steering bogie (3) includes: a bogie frame (7); first and second axles (9) arranged at front and rear sides in a car longitudinal direction, respectively, and extending along a car width direction; a steering mechanism (30) configured to rotate both the first and second axles (9) relative to the bogie frame (7) to perform steering; first and second electric motors (12) supported by the bogie frame (7), arranged at the front and rear sides in the car longitudinal direction, respectively, and including first and second output shafts (28), respectively, the first and second output shafts (28) being parallel to the first and second axles (9) at the time of non-steering; first and second reducers (13) connected to the first and second axles (9), respectively; and a first constant velocity ball joint (15) by which the first output shaft (28) is coupled to the first reducer (13) and which follows rotations of the first axle (9) at the time of steering to allow relative displacement between the first output shaft (28) and the first reducer (13), and a second constant velocity ball joint (15) by which the second output shaft (28) is coupled to the second reducer (13) and which follows rotations of the second axle (9) at the time of the steering to allow relative displacement between the second output shaft (28) and the second reducer (13).
