Definitions
- the present invention relates to a device for collecting electrical energy on the ground and vehicle guidance, and an urban transport vehicle equipped with such a device.
- the present invention relates in particular to the field of urban transport, automatic or not, people.
- the propulsion is generally electric, while the guidance is achieved through a rail or several.
- the most frequently used technique is to have in the path of the vehicle overhead cables which connects said vehicle.
- the disadvantage of this technique is essentially aesthetic, and in order to overcome it, the alternative of the underground feed has been proposed.
- the guiding is carried out by means of rails arranged on either side of the decking and in which the vehicle to be moved rolls, whereas in the document EP 1 694 525 it is realized at the level of the slit practiced in the decking.
- the guide rail has many disadvantages in urban areas, because the turns are tight, including noise and premature wear of the rails and / or wheels or rollers due to the great pressure exerted by the weight of vehicle.
- the document DE 76 067 also describes a tractor which rolls in an infrastructure and which captures the energy necessary for its advancement on bare conductors arranged along the ceiling of said infrastructure, while the surface vehicle rolls on rails, presenting the same disadvantages mentioned above.
- the vehicle of document DE 36 01 128 has the particularity of being equipped with two engines, on the one hand it comprises a combustion engine, and on the other hand it is connected to an underground tractor operating with electrical energy, intended to take over the combustion engine when passing in places that require calm and / or in which no exhaust gas must be emitted.
- the vehicle is guided on the surface by means of lateral slides, against which side wheels of vertical axes are rolled. If this vehicle does not have the drawbacks of rail guidance, it remains cumbersome since it requires that it be reserved a traffic corridor, bordered by the slides.
- the aim of the present invention is to overcome these various drawbacks by proposing a device for collecting electrical energy on the ground and for guiding a vehicle, making it possible to supply electrical energy to a vehicle through bare conductors, without these are accessible to people, and to get rid of superstructures, requiring only infrastructure.
- the device for collecting electrical energy on the ground and for guiding a vehicle comprises bare conductors under tension arranged in a gutter formed in the carriageway and closed by a decking, while on the one hand a sensor means comes to the contact of said conductors through a slot in said decking, and that secondly said vehicle comprises an electric motor powered through said sensor means, and which allows to move directly or indirectly said vehicle, and it is characterized in that said conductors consist of rails and said sensor means consists of a carriage adapted to roll on said rails and to be guided by them; and in that said carriage is mechanically connected to said vehicle through an articulated arm, and that it is provided with measurement means provided for measuring the direction and the amplitude of displacements of said arm with respect to said carriage, and transmit these data to the control means of the steering members of said vehicle, so as to correct the path of said vehicle.
- the guidance of the vehicle is achieved by an action on the steering members thereof.
- the carriage follows them but not the vehicle, which generates a movement of the articulated arm relative to the carriage, and more particularly to the main axis of movement of said carriage.
- Measuring means appreciate the direction and the amplitude of this movement of the arm, and these data are transmitted to the control means of the steering members, which then correct the trajectory of the vehicle.
- the carriage comprises four wheels, each with a conical tread and a guide bead, connected two by two in rotation, while the rails are mushroom type.
- the carriage is placed in front of the articulated arm and is pushed by the vehicle.
- the carriage is disposed behind the articulated arm and is pulled by the vehicle.
- the articulated arm comprises a substantially horizontal portion connected to the vehicle at one end through a first hinge type ball joint, and by its other end, through a second hinge type ball joint, to a mast which rises from the carriage and which is engaged in the longitudinal slot, said second hinge being disposed above the decking which closes the gutter made in the floor.
- the articulated arm is associated with control means which comprise on the one hand sensor means able to measure the angle formed by said arm with the longitudinal axis of the vehicle, and secondly means of action on the direction of said vehicle, adapted to allow a proportional trajectory correction.
- Such a device for collecting electrical energy on the ground and guiding finds a particular application in the field of urban transport, and allows the implementation of a light vehicle, automatic or not, for the transport of people.
- the present application also relates to a vehicle for the urban transport of people, mounted on rubber or tire wheels, rolling freely on the road, stepping over the gutter closed by the decking, and which is supplied with electrical energy and is guided by a device for collecting electrical energy on the ground and guiding as described above.
- the vehicle is, preferably, hydraulic type propulsion, performed through a variable volume hydraulic pump driven by an asynchronous or synchronous electric motor rotating at a constant speed, and driving one or more hydraulic motors.
- FIG. 1 represents a schematic cross-sectional view of a device for collecting electrical energy on the ground and for guiding according to the invention.
- Figure 2 shows a schematic plan view of a portion of the same device.
- FIG. 3 shows a partial schematic side view of the same device.
- FIG. 4 represents a schematic side view of a vehicle equipped with the device for collecting electrical energy on the ground and for guiding according to the invention.
- - Figure 5 shows a schematic plan view of the same vehicle.
- FIG. 1 it is possible to see a device 1 for collecting electrical energy on the ground and for guiding according to the invention, intended to take place in the roadway C.
- This device 1 comprises a gutter 2 made of concrete, closed superiorly by a decking 3 made in two parts 30 and 31 separated by a longitudinal slot 32, width prohibiting the passage of a hand and thus access to the gutter 2.
- the channel 2 presents below and longitudinally a channel 20, and laterally at a median height, disposed on either side of the channel 20, two steps 21, each supporting a rail 22, an element 23 of electrically insulating material being interposed between the redan 21 and the rail 22.
- the channel 2 also comprises a groove 24, made laterally and longitudinally, above the level of the steps 21, and which houses high-voltage conductors 25 for the supply of transformers, not shown, placed cyclically in the channel 2. These Transformers are intended to energize the rails 22 which constitute bare conductors.
- a carriage 4 comprising a chassis 40 mounted on four wheels 41.
- the wheels 41 are of the railway type, they are metallic, and comprise a tread 42 conical and a guide flange 43, while the rails 22 are of the mushroom type.
- the carriage 4 is secured to a vehicle 5 rolling on the roadway C, above the channel 2, via an articulated arm 6 which comprises a substantially horizontal portion 60, connected to the vehicle 5 at one of its ends through a ball 61, and connected by its another end through a ball 62 to the carriage 4, and more exactly to the end of a mast 44 fixedly secured to the carriage 4, and which emerges vertically from the channel 2 through the slot 32 of the decking 3.
- an articulated arm 6 which comprises a substantially horizontal portion 60, connected to the vehicle 5 at one of its ends through a ball 61, and connected by its another end through a ball 62 to the carriage 4, and more exactly to the end of a mast 44 fixedly secured to the carriage 4, and which emerges vertically from the channel 2 through the slot 32 of the decking 3.
- the decking is, optionally, provided with a covering element 33, made of flexible material, capable of covering the slot 32, visible in FIG. 1, and which retracts during the passage of the mast 44.
- the articulated arm 6 contains electrical conductors, not visible, for transmitting to the vehicle 5 the electrical energy sensed by the wheels 41 on the rails 22. This electrical energy is used to supply a motor means adapted to drive the vehicle 5 .
- the rails are supplied with low voltage current, less than 1000 V, single-phase 50 Hz, and it supplies an asynchronous or synchronous electric motor rotating at constant speed, to drive a variable volume hydraulic pump, which it even feeds one or more hydraulic motors.
- the electric motor, the hydraulic pump and the hydraulic motor or motors are installed in a vehicle 5 such as that shown in FIGS. 4 and 5.
- This vehicle 5 is mounted on rubber or tire wheels 50 and is designed to rolling freely on the road, being guided by the carriage 4 to which it is connected.
- the vehicle 5 comprises steering members acting on steering wheels 50, managed by means of controllers comprising means for measuring the angular deviations formed by the portion 60 of the articulated arm 6 with, for example, the longitudinal axis of the vehicle or the orientation of the steered wheels 50, so as to act on the steering members in order to correct the trajectory of the vehicle, as shown in Figure 5.
- the carriage 4 ensures, in addition to the capture of electrical energy, the guidance of the vehicle 5 without the slightest stress being applied to the wheels 41 on the rails 22, thus generating only a small amount of noise and wear and tear on the wheels. elements in contact.
- the carriage 4 is pushed on the rails 22 by the vehicle 5, but it is perfectly possible to provide another configuration in which it is pulled.
