The invention describes a traffic system especially with vehicles driven by electricity as trolley busses but also and at the same time for instance trucks and private cars driven by electricity. The collector (4) is always perpendicular to the length of the vehicle (3) also when the collector is out from the sides. It is pressed in the direction towards the wire pair (1) just so much to keep the mean pressure of the wires on the contact shoes (22) about the same in both directions. This decreases or removes the risk for derailing. The driver can quickly and automatically without alighting return still derailed collectors. Should a vehicle stop with the collector on a spot icy or else lacking voltage, the collector is pulled forward a distance to regain voltage. In switches the collector is pushed to the correct line by the driver, the wheel or automatically directed by an outside signal. Should arcs develop the current is automatically cut electronically. A simple computer industrial type can co-ordinate the values measured on the vehicle and outside signals, if any. |
