  • Publication number: 20140338558
    Abstract: A rail vehicle system includes a set of cars for transporting passengers. The set has two end cars, at least one driveless central car and at least one central car constructed as a traction car having at least one drive unit. In order to achieve greater flexibility in assembling a rail vehicle system, in particular with regard to improved scalability of traction power, the traction car includes a power supply unit for the drive unit and has at least one voltage transformation unit and a power converter unit.

  • Publication number: 20140216878
    Abstract: Disclosed is a non-contact power feeding apparatus using a conductive fluid, through which an electric railroad vehicle or a trolleybus receives required power from a contact wire in a non-contact state by using the conductive fluid. The non-contact power feeding apparatus according to the present invention includes: a fluid injection hole defined in a vehicle to inject the conductive fluid toward the contact wire; a conductive fluid container for supplying the conductive fluid that is injected through the fluid injection hole; a pressing pump for injecting the conductive fluid within the conductive fluid container through the fluid injection hole; and a current collection terminal disposed on a side of the fluid injection hole to receive the power from the contact wire in a non-contact manner by using the conductive fluid as a medium.

  • Publication number: 20130270050
    Abstract: A slider is slightly moved in a direction in which both side surfaces of the slider come in contact with inclined surfaces of impact mitigating parts of neighboring contact strip pieces. For this reason, the inclined surface of the impact mitigating part of the contact strip piece which the slider approaches is relatively downwardly slid with respect to one side surface of the slider. In addition, the inclined surface of the impact mitigating part of the contact strip piece from which the slider moves away is relatively upwardly slid with respect to the other side surface of the slider. As a result, since an impact generated between the contact strip piece and the slider is mitigated by the impact mitigating part without fitting the slider into a stepped section between the neighboring contact strip pieces, the slider is smoothly transferred from the one contact strip piece of the neighboring contact strip pieces to the other contact strip piece.

  • Publication number: 20130105263
    Abstract: A pantograph assembly configured to transfer electrical power from an overhead conductor to a machine. The pantograph assembly includes a pantograph support detachably connected to the machine, an articulated assembly, a pan rail and a carbon brush. The pantograph support includes a first link, and a second link hingedly connected to the first link. The first link is connected to the pantograph support. The pan rail is supported by the second link of the articulated assembly. The carbon brush is supported by the pan rail along a longitudinal axis of the pan rail. The pantograph assembly further includes an end horn having a bridge portion connected to the carbon brush. The bridge portion is configured to transfer the overhead conductor between the end horn and the carbon brush.

  • Patent number: 7870938
    Abstract: An object of the present invention is to realize a structure able to well retain contact performance between an overhead line and a slider 7b, across the entire lengthwise direction of the slider 7b. The slider 7b formed of slider elements 34a and 34b divided in the crosswise direction of a vehicle, is supported on the upper surface of a slider support body 9. A center support member 12 forming the slider support body 9 is elastically deformed downward in a concaved shape across the longitudinal direction, due to a load applied due to contact between the overhead lines and the slider 7b. Also, together with this, both ends of the center support member 12 are supported on a shoe body 3a so as to allow free oscillation via the respective end section support members 13.
