    Vehicle 1 here is externally made of an "A-Ford", but this is here converted toa battery-powered vehicle.
    The vehicle 1 according to the invention shall then comprise a steering equipment or a steeringso that a driver "F" (not shown) can drive and steer his vehicle along saidroad section 2 with assigned road sections 2a1, 2a; 2a1 ', 2a' and a circuit 10 forraise and lower the control means (4).

    Figure 2 illustrates a contact means 40 (40 '), with two identical avoidable onescontact units 41, 41 ', in a position where the two cooperate with one and the same trackassociated contact surface 4a ', figure 3 illustrates in a perspective frontal view one, iselected direction of travel, first avoidable contact unit 41 during its cooperationwith the groove and the contact surface 4a 'and the figure 4 illustrates the two identicalfoldable contact units in an elevated position where both of their displacementmovements "P" towards and past a fixed obstacle "H" turned towards and to this showntop position.
    A vehicle-related, a track 51 inserted in a road section 2a1 'with power supplyand energizable contact surface (s) 4a ', from loose and / or solid obstaclescleaning and / or avoidable contact means 40 and / or contact unit, shall be includeda first contact unit 41 is rotatably attached to a vehicle-associated arm unit 14 andarranged rotatably about a horizontally oriented axis of rotation 41a, so as tobe able to turn the fixed obstacle "H" from a position which can cooperate with the contact surface 4a ',according to figure 2, to a contact surface 4a 'exposing position, according to figure 4 and viceVGFSG.
    Said first contact unit 41 is, in a selected direction of travel "P" for the vehicle, designedwith at least two parts 41 b, 41 b ', a first electrically insulating part 41 b, for oneprotecting an electrically conductive second portion 41 b ', and wherein the first portion 41 band the second part 41 b 'are oriented, in a selected direction of travel of the vehicle, aftereach other and to a longitudinal extent towards the groove 51 and the contact surface 4a 'corresponding orientation.lO15202530The first part 41b is thus formed as an electrically insulating part, such as onepart formed of plastic material, and thereby shaped and arranged to only partiallybe able to enclose the extent of the second electrically conductive part 41 b ', in particular thatpart facing from the contact surface 4a 'and thereby having an upper portion 41c for onerotatable engagement with said axis of rotation 41a.
    The upper portion 41c, adjacent to said axis of rotation 41a, is adapted to cooperate witha resilient member 41d, dimensioned to be able to hold the contact unit 41 withits first part 41b and its second part 41b 'integrated therewith in one with the contact surface 4a'cooperating mode. This resilient member 41d may be sized to includea limited force cause the second part 41b 'and its surface area 141b' to be pressed downagainst the contact surface 4a '. The contact unit 41 is brought against the action of the resilient memberto the position shown in Figure 4 for turning the action of the resilient memberreturn to the position shown in Figure 2.
    The upper portion 41c, within an area 41e over the axis of rotation 41a, is formed witha first abutment surface or support surface 41f, adapted to hold the contact unit41 in a position cooperating with the contact surface 4a 'and a second abutment surface 41g,suitable to serve as a stop for the maximum rotation of the contact unit 41movement from a cooperation with said contact surface 4a ', according to figure 4.
    The first 41f and the second abutment surface 41g are adapted to be able to cooperatewith a lug-shaped means 14a, formed into a vehicle-associated arm unit 14 and itssupport arm 14b.
    An arm unit 14 associated with the middle pair 14b 'is arranged to cooperate with theassociated arm unit 14 via a horizontally oriented axis of rotation 14c andwhere the center portion 14b 'of the arm portion 14b, 14d' are both directedadapted to support each horizontally oriented axis of rotation 41a, 41a ', one forwas its contact unit 41, 41 '.lO15202530The first part 41 b should be formed from a material which has a lower wearstrength and be less abrasion resistant than the material of the other part41 b 'is formed from.
    In combination with the action of the resilient member 41d, even wear should occurof the surface sections 141b, 141b 'can be fulfilled.
    The arm unit 14 can advantageously be pressed downwards by a resilient member (not shown) so thatthe same contact pressure must be realized for the two contact units (41 andsurface sections 141b, 141b ').
    The lengths of the surface surface facing the contact surface 4a ', oriented along the groove 51the sections 141b, 141b ', for the first part 41b and correspondingly for the second part41 b ', are mutually assigned a mutually selected relationship, falling within the rangebetween 0.1 and 0.5, such as about 0.3.
    The two contact units 41, 41 'are separated from each other by a selected distance 44'along the longitudinal extent of the groove 51 and where this distance is assigneda selected ratio, related to the longitudinal extent of the contact units (41)(141b, + 141b ') along the groove 51 and the contact surface 4a', falling within an areabetween 1.0 and 0.5.
    Two identical, or at least substantially identical, parallel contact means 40, (40 'not shown) with contact units 41, 41 'are coordinated side by side (parallel orientedfor a collaboration with each of its contact surfaces 4a ', 4b' assigned to each of themtwo parallel tracks 51, 52.
    The first part 41b may then be formed from a soft carbon material, a soft ceramicchemical material and / or from a soft plastic material, while the other part41 b 'can then be formed from an electrically conductive specially treated hard material,such as a carbon material.
    The resilient member 41d is here formed into a planar helical shape, such as a helical shapejoining Archimedes' spiral.lO15202530Figure 3 illustrates an orientation of a contact surface 4a 'and a conductor 4c for an O-potential or a protective earth connection and where the movable contact unit 41height should be less than the distance between an upper edge (4a ') of the contact surface 4a' anda lower edge 4c 'for the conductor 4c and an insulating distance added thereto.
    The embodiment described here has been found to work well in a collision with a solidobstacle "H" at a vehicle speed of 100 km / h.
    The sides of the contact unit do not need to be electrically insulating on the contact unitsecond part 41b 'is assigned a height dimension which means that it does not reach up to onelower edge 4c 'of the protective cover or conductor 4c when the protective cover is connected to the groundtential 4c to ensure personal safety.
    By choosing an electrically conductive and / or an electrically insulating material in itthe first part 41 b of the cleaning agent and an electrically conductive material in the secondpart 41b ', these two parts can be fixed to each other without the need to move with themusing spring devices.
    In the event of wear of the surface sections 141b, 141b 'of the contact unit 41 during a displacement alongthe contact surface 4a 'always comes the cleaning agent and / or the surface section 141 bto wear slightly more than the surface section 141 b 'and to be worn down by smaller particles on thethe roof surface 4a 'and thus the contact surface 4a' is initially cleaned before an electrical contactwill occur between the surface section 141 b 'and the contact surface 4a' and therebya wear will follow parallel downwards about the axis of rotation 41a, 41a 'and perform their various functions.
    A resilient member 50 is adapted to actuate the contact unit (41), or contact member.units (41, 41 '), towards and to a co-operation with the contact surface 4a' via the surface sections141b, 141b '.
    The invention is of course not limited to the embodiment given above by way of example.but can undergo modifications within the scope of the inventive conceptillustrated in the appended claims.
    Special consideration should be given to the fact that each unit and / or circuit shown can be combined with eachother displayed unit and / or circuit within the framework of being able to achieve the desired technicalfeature.
