A subframe 50 is connected via a vibration isolator 40 to a floor 11 of a railway car body 10, and the subframe 50 has a center pin 60 protruding downward therefrom and connected to a bogie 30. The subframe 50 is connected to a coupling device 70, and is disposed so as to come into contact with stoppers 13 on side beams 12 of the car body 10. According to this structure, since the coupling device 70 is not directly connected to the car body, there is no need to weld a rigid member to the bottom surface of the floor 11, and the railway car body can be manufactured easily. Moreover, since the subframe 50 is connected to the floor 11 via a vibration isolator, less noise is transmitted to the car body. Power is transmitted from the coupling device 70 or bogie 30 to side beams, so the structure of the car body can be simplified.

摘要:
A controller for an electromagnetic actuator comprises a pair of springs acting on opposite directions, and an armature connected to the springs. The armature is held in a neutral position given by the springs when the armature is not activated. The actuator also comprises a pair of electromagnets for driving the armature between two end positions. In response to a release of the armature held in one of the end positions, the controller applies brake to the armature according to a load condition of the armature. In high-load conditions, the valve can surely be opened without additional electric power. In low-load conditions, the armature is prevented from colliding with a yoke of the electromagnet. The application of brake includes over-excitation operation, flywheel operation and suspension of power supply. In the over-excitation operation, voltage is applied to the electromagnet corresponding to one of the end positions from which the armature is released for a first period. The first period may be determined according to a load condition of the armature. After the first period elapses, flywheel current is supplied to the electromagnet for a second period. After the second period elapses, power supply to the electromagnet is suspended. Appropriate combination of over-excitation operation, flywheel operation and suspension of power supply allows the braking force to be adjusted according to a load condition of the armature.
