    For creating a selected and required propulsive effect and / or a speed adjustment and / or control.
    The invention is intended to be able to be applied to road sections in the form of public and private roads and along its road sections, but can also be used in industrial plants, with different requirements for power requirements and energy needs.
    The invention intends to e.g. at the same time as an energy charge of the battery set from the external energy source to supply the power and energy that will be required for a selected, for the vehicle driving upwards and over an upwardly sloping road section adapted, power requirements.
    More particularly, the present invention provides such a system where a non-tracked vehicle, such as a truck, during its driving along selected road sections with its vehicle-assigned battery set can be supplied with a complementary power and energy, such as from the external energy source or from a vehicle-related energy source, such as a diesel generator. In this regard, the present invention proposes a "first" vehicle-related energy source, such as a diesel generator, a "second" vehicle-related energy source, such as a battery set, and a "third" vehicle-separated and external energy source, such as voltage-capable electrical two or more conductors built into tracks in successive road sections, and where the conductors for a selected road section are electrically isolated from the corresponding conductor for an adjacent (previous or subsequent) road section.
    The present invention is based on two or more conductors being built into a track in their road section and where the track (not the conductors) extends continuously from road section to road section.
    The voltage assigned to these energizable conductors can be an AC voltage (with a vehicle-related rectifier) or a DC voltage. When selecting a direct voltage, one conductor can be positive while the other conductor can be negative and an additional conductor assigned ground potential or zero potential, whereby the vehicle can be operated with double the voltage value.
    In the case of alternating voltage to the conductors for the road sections, this can advantageously be arranged in opposite phase and symmetrically around an earth potential or O-potential.
    The motor intended for driving the vehicle may be a direct current type or of an alternating current type, in which case the motor must be connected to an inverter.
    BACKGROUND OF THE INVENTION Methods, arrangements and constructions, related to the above-mentioned technical field and nature, are previously known in a number of different embodiments.
    In the case of electrically powered vehicles, these can advantageously be categorized as "rail-bound vehicles" or as "non-rail-bound vehicles".
    “Rail-bound vehicles” are driven along their road section and road sections of parallel rails laid in the road section or exposed via slippers, which guide the vehicle's fixed wheel pairs. "Non-rail vehicles" are driven along their road section and road sections over a carriageway and are driven along the road sections via a control equipment belonging to the vehicle.
    The present invention is based on and is intended to be utilized in the latter category and technology, and is primarily intended to be able to be applied to heavy goods vehicles, with or without coupled trailers, where it is known, through the patent publication US-4,129 203-A, a vehicle-related arrangement for causing the vehicle underlying contact springs, up and down and laterally, towards and to a mechanical and electrical interaction with or from an interaction with the non-energized electrical conductors of the road section (14). insulated surface sections.
    Here, the use of an insulator (16) within a channel (18) which supports the conductors in the form of rails (14) is indicated. A cover plate (20) formed with a slot (12) is removably attached to the upper and opposite wall portions of the channel (18), this cover plate (20) being adjusted to a plane adjoining the upper surface (20) of the road section. 22).
    Figures 2 and 3 of the patent publication indicated describe a vehicle-related table (98) and to which table an arm (10) is rotatably attached (94, 96, 99). Sensors (30) assigned to the table (98) generate signals which, with respect to phase position and size, indicate the direction and distance from a axis of rotation (99) to the slot (12) in the cover plate (20), which is based on changes in an generated magnetic field. Via a designated mechanism (31), the table (98) and the arm (10) can be driven by a motor (32) between predetermined limits and limit switches (40, 41) located there.
    From the patent publication WO 93/10995-A a system is previously known for having electrically drivable vehicles driven along a road section and its road sections.
    Figure 9, in the patent publication specified here, clarifies the system's basic structure.
    It is indicated here that the road section (14) and its road sections are provided with electrically conductive road sections (300a - 300f), where a road section can be considered to correspond to a road section.
    The vehicles (310) have an electric motor (320) and two (312, 314) or three (312, 312 'and 314) underlying contact springs, adapted for a mechanical and electrical contact with the electrically conductive conductors, the lengths of which are adapted to correspond a selected length (identically equal lengths) for utilized road sections or sections.
    The electrically conductive conductors within the road sections (300a - 300f) are arranged one after the other with a medium-oriented free space (302a - 302e), in order to prevent a short circuit via trailing contact springs (312, 312 ', 314).
    Every other road section (300b, 300d, 300f) is here continuously connected to a reference voltage (earth potential) while the other road sections (300a, 300c and 300e) are either directly connectable to a DC voltage source (440) or via a coupling means (304a, 304b, 304c) connectable to any suitable source of electrical energy (308), when a vehicle is nearby.
    When using an embodiment with three contact springs, the distance between them must be chosen so that two or three contacts are always in an electrical contact with two opposite polarity road sections and that neither of the two contacts can be able to short-circuit the free space (302a - 302e) between two adjacent sections.
    The system here requires for its function specially designed vehicles (310), where a selected distance between front (314) and rear (312, 312 ') contacts must be identically equal and further selected slightly longer than the equal lengths of the road sections (300b, 300d).
    Thus, specially designed vehicles with front and rear contacts are required and where each of the road sections used (300a - 300f) must be selected with equal lengths and oriented one after the other in the direction of travel of the vehicle with equally free and intermediate spaces (302a - 302e) .
    The patent publication otherwise indicates the presence of a single live conductor or rail within a road section (p. 5, lines 11-13), and that a vehicle should be able to apply voltage to a preceding road section (p. 5, lines 19-21; p. 6, lines 7-10; p. 8, lines 28-32).
    Furthermore, it is instructed that voltage-adjustable rails (16) must be provided with side-by-side drainage grooves (p. 9, line 14).
    An absence (or presence) of an activation signal must be able to affect a control unit (38) (page 8, lines 23-27).
    The required distance between vehicle-related contacts is stated on the side. 10, line, 17-20 and an utilization of activity-initiating radio signals is proposed on p. 11, lines 2-4 and p. 14, lines 1-16. 10 15 20 25 30 Furthermore, it is proposed, on p. 15, lines 21-23 and p. 16, lines 1-15, an utilization of a Hall element (240) and its connection to an amplifier (246). Alternatives to this are further illustrated on page 17, lines 3-9.
    It is also known to electrically drive a vehicle along a stretch of road by means of an inductive energy transfer, acting between a vehicle and an underlying road section.
    As an example of this prior art, reference is made to the contents of patent publications US-3,914,562-A and US-4,007,817-A.
    The present invention intends to concentrate on a vehicle-related arrangement in the form of a contact means for up and down and laterally influencing the vehicle underlying the means of contact or the pantograph, in order to be able to coordinate the use of a first and / or a second vehicle-related energy source. such as a diesel generator and a battery set and / or a vehicle external energy source, arranged along the road section and its road sections and with its upwardly open tracks connecting to each other from road section to road section, but with two or more parallel electrical conductors for each road section.

    With reference to the appended figures, the basic preconditions for the present invention and where the significant peculiarities associated with the invention have been concretized are thus shown schematically and in detail, through the embodiments now proposed and described in more detail below.
    Thus, Figure 1A shows a vehicle 1 which can be propelled electrically and by one or more batteries or a set of batteries, driven along a stretch of road 2 77 and its road section 2a1 and 2a1 'adapted system ”S 10 15 20 25 30 16 The vehicle 1 is constituted here exterior of a "T-Ford", but this is here converted to a battery-powered vehicle, with a continuous access to an external, a third, energy source, here designated "s1", "lll".

During this time duration tf, - ts, full power can be obtained from the energy source “ll” and a small excess can be allowed to charge the battery set “ll”. The invention is based on the battery set "B" and the second energy source "ll", but in particular the third energy source "lll" in the first place, shall, via the distribution circuit "R1", supply the motor 5 and for this purpose the battery set "is required. ll ”,“ B ”has stored an energy and is otherwise dimensioned to drive the motor 5 at full power.

The system "S" proposed according to the invention shall then primarily comprise: "a one or more, via separate electric motors 5 or motors, electrically drivable vehicles 1, 1b and where resp. vehicles have a power distributing and / or regulating control circuit "R1" within the control circuit 100, for creating a required power and / or a speed control via the control circuit "R2" and the accelerator pedal 100a.
    The required output power shall be provided primarily by the in-vehicle energy source “ll”; “B” and which shall be secondarily under maintenance charge from the third energy source “lll”; “s1.” The road section 2 is shown subdivided into road section 2a (2a1, 2a2, 2a3; 2a1 ', 2a2' and 2a3 '), each of which should advantageously be assigned an external energy source "lll", illustrated here as a number of electrical stations "s1".

    The auxiliary motor 7 and the auxiliary motor 8 can both be actuated in a reciprocating movement, where a first movement is activated via a first signal on a first conductor 7a and 7, respectively. a first signal on a first conductor 8a, while a second (opposite) movement is activated via a second signal on the conductor 7a resp. 8a, while the instantaneous setting positions of the motors 7, 8 and the carrier 6 are evaluated by one or more sensors (not shown) and indicated via an generated signal on a second line or conductor 7b resp. 8b.
    These signals on the first conductors 7a, 8a are generated in a central unit or control circuit 100 with a control equipment 10 and signals on the second conductors 7b and 8b are generated within the same central unit 100, using position sensors (not shown).
    The central unit 100 with the control equipment 10 is a complex unit, which i.a. via a sensor 16 should be able to sense the presence and orientation of the conductors 4a, 4b and then lower the pantograph 4, via the auxiliary motor 7, to an electrical contact with these conductors 4a, 4b, which is illustrated here as live or vice versa.
    Via a connection 10a to the central unit 100 and its control circuit "RZ", the power and energy which is supplied to the engine via the energy source distributing circuit "R1" is regulated. For this purpose it is required that the circuit "R1" is directly controlled by an accelerator pedal 100a (figure 1G) to supply the required power to the motor 5 via the control circuit "RZ".
    In the position shown, the current collectors 4 conduct current and voltage from the energy source "s1"; "| ll" to the power and energy distribution circuit "R1". This or a control circuit "R2" senses via the central unit 100 the power requirement for the motor 5 and primarily causes the motor 5 to be supplied with the power it needs, according to the input signal on the connection or line 10a and generated output signal on the connection or line 10b 20 25 30 20 and thus the stationary system "s1", "lll" shall be loaded and supplement the power and energy requirements via the battery set "ll", A parallel connection of the vehicle externally drawn power "lll", "sl" and the vehicle internally generated the effect "G" and / or "ll", "B" can here be realized via the control circuits "R1" and "R2" and with the aid of the control circuit 100.
    Via line 10a information to the central unit 100 is input about a desired speed and associated power for the vehicle 1 and via internal circuits (not shown) and the function "R2", "10" is influenced via line 10b the circuit "R1".
    Figure 3 shows, in an end view, a vehicle 1 (1b) with its downwardly directed pantographs 4 in a mechanical and electrical interaction with the two live conductors or rails 4a, 4b assigned to the road section 2a1 ', and a ground connection 4c.
    Figure 4 shows an electrical connection arrangement "K1" where road sections on road sections 2a1, 2a2 and 2a3 and 2a1 ', 2a2' and 2a3 ', respectively, with their station after station "s1", "s2", "s3" and "S1" s2 '"and“ s3' ”, can be activated and energized from one and the same superior charging source“ | II ”, 42, via coupling means and switches 43a, 44a, and 45a, combine the road section 2a and 43a ', 44a' and 45a 'for the opposite road section 2b, as a vehicle 1 will pass along the electrically separated, d also longitudinally coordinated tracks, road sections 2a, 2b.
    This requires a number of switches or switching means (switches) for a connection and disconnection of the stations "s1", "s2 '", where this connection and disconnection can take place via stationary sensors (not shown) related to the road section.
    The present invention is based on the above conditions and indicates, according to Figure 5, that a pantograph 41 resp. 42 is intended to be able to run freely along the track 51 oriented to the road section 2a1.
    The pantograph is, according to Figure 7, formed from a main part 141 formed of an electrically insulating material, the lower surface 142 of which facing the energizable conductor 4a 'is formed flat, or at least substantially flat, with a within said lower surface 142 formed, consisting of an electrically conductive material 143, lower contact surface 144 (149, 149a) and that the electrically conductive material 143 is arranged to extend through the main part 141 to the upper surface 145 of the main part. forming one or more upper contact surfaces 146, 146a or connecting conductors 146b.
    The main part 141 is associated with a surface extension along the groove 51 and with a thickness adjoining the width of the groove 51, with a shape of one or adjoining the shape of a parallelogram or an oblique parallelepiped.
    The upper 145 and lower surfaces 142 of the parallelepiped or main body 141 are fitted in parallel.
    Two or more pantographs, 41 and 41 'are, according to Figure 7, for an extension along the groove 51, coordinated with one and the same voltage-setting conductors 4a' and otherwise adapted to form parallel-connected current paths.
    Figure 7 illustrates that a first main part 41 is associated with a parallelepipedic shape which deviates from a parallelepipedal shape of a second main part 41 '.
    To said lower surface 142 for a main part 141 are formed two or more lower contact surfaces, designated 149, 149a.
    A resilient member 150, 150 '(according to Figure 5) is adapted to have the pantograph 41, 41' and its main part 141, 141 'and its lower contact surface 144, or lower contact surfaces 149, 149a, pressed against the energizable conductor 4a' .
    Two or more pantographs 41, 41 'resp. 42, 42 'are parallel oriented and assigned to each of two or more parallel grooves 51, 52, according to Figure 5.
    The pantographs 41, 41 '; 42, 42 ”are, with at least their lower contact surfaces 144, 149, 149a, formed of steel, stainless steel, copper, brass, bronze, aluminum and / or hard carbon. 10 15 25 25 30 22 The pantograph is assigned at least one lower contact surface and that this is shaped as a brush unit, consisting of steel, stainless steel, copper, brass, bronze, aluminum and / or hard carbon.
    The energizable conductor 4a 'is formed from steel, stainless steel, copper, brass, bronze, aluminum and / or hard carbon.
    The lower contact surface 144, 149, 149a is adapted to support with said force of between 1 and 15, such as 2 - 5 or about 3 N / cm 2, against said voltage-conductable conductors 4a '.
    The two or more energizable conductors, such as 4a ', are coordinated to the bottom of the respective tracks 51, 52 within a duct 30, according to Figure 6.
    Said energizable conductors 4a ', 4b' are shaped as rails or bands, with an upper wide contact surface and with a limited thickness.
    The channel 30 as an unit is elongate and shaped elastically, so that it can be bent into a roll.
    The contact 144 (149, 149a) consists of hard carbon and to which two or more conductors 146b are attached, according to Figure 7.
    Figure 8 illustrates in side view an alternative embodiment of a contact means in the form of a pantograph with a duct 81 adapted for compressed air within the front portion of the pantograph, in the direction of travel, in an intention to air flush away less polluting particles such as sand. from the conductor 4a before making a contact closure with the contact surface 144.
    Figure 9 illustrates in side view a further alternative embodiment of a pantograph with ducts 91, 91a, 91b adapted for compressed air, where the duct 91 is to be regarded as a connection duct to a source of compressed air (not shown) while the ducts 91a, 91b and so on. forms a fan shape, with a constant cross section towards the conductor 4a, a divergent cross section towards the conductor 4a and / or a converging cross section towards the live conductor 4a. Figure 10 then illustrates in side view an embodiment of a pantograph with a channel 101 adapted to a negative pressure within the front portion of the pantograph, in the direction of travel, in order to suck away less polluting particles such as sand from the conductor 4a.
    In Figures 8 and 9, it is proposed that the air jet should be generated with compressed air, which can typically have a pressure of 10 bar.
    The air jet has a high speed, in the order of 100 m / s, so it does not matter much if the vehicle 1 moves forward by up to 30 m / s.
    The air jet will clean sand and dust effectively before the pantograph itself with its sensitive sliding contact 144 arrives.
    The compressed air is generated with a compressor in the vehicle and is led via flexible hoses to the pantograph 141.
    With compressed air, it can be advantageous to use this to allow a cleaner to float on an air cushion and thereby minimize wear. In addition, the compressed air stream can be diverted forward, to clear away sand and dust.
    The sliding contact 144 is proposed to consist of a hard carbon and of the type that has come into use in pantographs for trams and trains.
    Figures 11 and 12 are intended to illustrate a pantograph 41 with a generating disc 41a generating disc 41a oriented in the direction of travel, oriented a distance above the conductor 4a.
    The invention is of course not limited to the embodiment stated above as an example, but may undergo modifications within the scope of the inventive concept illustrated in the appended claims. lO 15 20 25 30 35 40 45 24 Special consideration should be given to the fact that each displayed unit and / or circuit can be combined with any other displayed unit and / or circuit within the framework in order to be able to achieve the function of the island. kad technically
