Abstract

PROBLEM TO BE SOLVED: To simplify truck structure and to improve curve traveling performance by providing beams fitted to a truck frame through elastic bodies, integrally with a motor frame, and transmitting tractive force and supporting anti- torque of a main motor by the beams. SOLUTION: Wheel sets 3 with wheels and axles integrated are arranged at the front and rear of a truck frame 1 of a rolling stock truck. A stator is disposed in a motor frame 13, and a rotor fixed to a rotor shaft is provided on the inside to transmit driving torque from the rotor shaft to the wheel set 3. Motor beams 19 extended parallel with the moving direction of an electric railcar are fixed in the vicinity of both ends of the motor frame 13. In addition, motor beam support parts 20 are provided on the truck frame 1 side through brackets or the like to support the motor beams 19 through elastic bodies 21. In the motor beam support parts 20, anti-torque of a motor works as force in the direction of a continuous line arrow mark, and tractive force works as force in the direction of a dotted line arrow mark, but both can be supported.

In this case, the yaw stiffness of the wheel set 3 can be adjusted by changing the structure, such as by changing the shape of the elastic body of the motor beam support portion 20. However, by using one motor beam 19, the yaw stiffness of the wheel axle 3 becomes extremely small, so that the self-steering property is improved. With directional vibration, its stability generally decreases with increasing speed), but the limit speed at which it is stable decreases. Therefore, this embodiment has a structure suitable for a vehicle traveling at a low speed in a section with many sharp curves.
