Abstract

The invention relates to a current transmission device for stationary charging of electrical energy stores of devices and/or for mobile supplying of electrical drive units of devices having a current transmitter which is embodied as an articulated arm system, and which can swivel between a current-transmitting extended position and a current flow interrupting retracted position, an adjusting drive interacting with the current transmitter as well as a spring system interacting with the current transmitter, wherein the adjusting drive is self-locking-free and has a switchable electromagnetic brake device.

Claims

1. A current transmission device, said current transmission device comprising:

a frame;

a current transmitter arranged on the frame and including an articulated arm system that swivels said current transmitter between a current-transmitting extended position and a current flow interrupting retracted position;

a self-locking free adjusting drive driving the current transmitter between the current-transmitting extended position and the current flow interrupting retracted position; and

a spring system biasing the current transmitter toward the current flow interrupting retracted position; and

an electromagnetic brake device arranged at the adjusting drive, said brake device being either a closed-circuit brake device that unblocks swivel movement of the current transmitter when a voltage is applied to the closed-circuit brake device or an open-circuit brake device that defines a position of the current transmitter when a voltage is applied to the open-circuit brake device.

2. The current transmission device according to claim 1, in which said frame is fixed to a vehicle.

3. The current transmission device according to claim 1, in which said frame is fixed to a stationary charging current device.

4. The current transmission device according to claim 1, in which the brake device has an energy supply that is independent of an energy supply of the adjusting drive.

5. The current transmission device according to claim 1, in which the brake device and the adjusting drive have a common energy supply that interacts with a switching device.

6. The current transmission device according to claim 1, in which the current transmitter can swivel downwardly, upwardly, horizontally, and in an intermediate direction resulting therefrom.

7. The current transmission device according to claim 1, in which the brake device includes a manipulation device manually actuating the brake device.
