Abstract

A rail structure related to a track of a system adapted for electrically driving a vehicle along a roadway. The vehicle is provided with a current collector which is displaceable up and down and sideways in relation to the direction of transportation, in order to be brought into mechanical and electrical contact with elongated tracks positioned below the roadway and comprising a conductor adapted to be supplied with current and put under voltage. The rail structure comprises one or more tracks oriented parallel with external wall sections made of metal, and a partition separating the external wall sections and comprising an intermediate wall made of an electrically conductive material. Conductors are arranged in a lower portion of the tracks, respectively. The tracks comprise electrically insulating layers applied to surface portions facing each other of said wall sections and the partition, the insulating layers being coordinated with the lower portions and intended to support the conductors.

Abstract

An arrangement for metal detection related to a system adapted for electrically driving a vehicle along a roadway. The vehicle is provided with a current collector which is displaceable up and down and sideways in relation to the direction of transportation, in order to be brought into mechanical and electrical contact with elongated tracks positioned below the roadway and comprising a conductor adapted to be supplied with current and put under voltage. The detecting arrangement, comprises one or more coils arranged for sensing the variation of the magnetic field, based on a horizontal and/or vertical distance between the coils and metal parts belonging to the one or more elongated tracks.

Abstract

The present invention has its application to a system for driving an electric and by one or more batteries powered vehicle along a roadway, comprising “a” one or more vehicles, which may be driven by an individual electric motor or motors and where in the respective vehicles exhibit a power-controlling control circuit for creating the necessary power and/or speed control and wherein required power i.a. can be provided primarily by a chargeable can be provided primarily by a chargeable battery set associated with the vehicle and “b” a plurality of road sections road portions divisible for the roadway, each being allotted one or more vehicle external electric stations for charging the battery set thereby and/or for supplying necessary power and energy for driving the vehicle. The underneath side of the mentioned vehicle is provided with a contact means displaceably positioned up and down and sideways, counted in the direction of transportation. Said roadway and its road sections or portions exhibits an elongated track or groove, each road section is supporting two rails in the groove and disposed under the driving path of the road section or portion. The rails being supplied with current and voltage. Said contact means is coordinated with a control equipment for creating simple adaptation of the contact means for registering the contact means for mechanical and electrical contact against said two rails.
