Abstract
One aspect of the present disclosure provides a current collector for an electric railcar. The device comprises: a current-collecting member, which is arranged on the circumference of a wheel for an electric railcar so as to collect current from an electric railcar rail; a base member coupled to the electric railcar; and a transfer member that transferring power collected by the current-collecting member to the base member, wherein the current-collecting member comes into rolling contact with the electric railcar rail by means of rolling of the wheel so as to minimize friction.
Claims12
A current collector for an electric railcar comprising:
- a current collecting member arranged on a circumference of a wheel for an electric railcar to collect power from a rail for the electric railcar;
- a base member coupled to the electric railcar;
- and
- a transmission member that transmits the power collected from the current collecting member to the base member,
- wherein the current collecting member makes rolling contact with the rail for the electric railcar by rolling of the wheel to minimize friction.
A rail device for transmitting power to an electric railcar, the device comprising:
- a power transmission member for transmitting power to a current collecting member arranged on a wheel for the electric railcar,
- wherein the rail device is arranged on a rail for the electric railcar and makes rolling contact with the current collecting member to minimize friction.
A power line device for transmitting power to an electric railcar, the device comprising:
- a power transmission member for transmitting power to a pantograph provided with a movable mechanism mounted on a roof of the electric railcar,
- wherein the power transmission member receives power from a power line and transmits the received power to the pantograph, and
- wherein the power transmission member is configured in a roller shape and makes rolling contact with the pantograph to minimize friction.
