    Fast retraction current collector
    The present invention relates to a current pickup wiper on an electrical supply track for an electric railway vehicle, comprising a pad suitable for being put in sliding contact with said feed track, this pad being movable between a retracted position and a deployed position, an actuator capable of moving the pad between the retracted and deployed positions and a mechanical system connecting the pad to the actuator in order to convert a movement of the actuator into a displacement of the pad.
    Such a wiper is known and integrated in the Citadis trams of the plaintiff circulating in the city of Bordeaux. It has a skate. The pad can be retracted and deployed using an electric jack. To this end, the electric actuator acts on a mechanical system composed of arms forming a parallelogram.
    This wiper is designed for a rail network having a mainly overhead power supply by catenary interrupted by a few sections of ground supply. During tramway operation, deployment or retraction of the wiper only occurs occasionally when the tramway is stopped at a station and passes from a section of the aerial supply network to a section of ground supply or vice versa.
    Such a wiper is not suitable for a rail vehicle such as a tram which circulates on a network where the tram must constantly alternate between a supply by the ground and another supply such as an autonomous supply by on-board battery.
    An object of the invention is therefore to provide a wiper for a railway vehicle with electrical power supply which alternates frequently, in particular during full travel, between a power supply by the ground and another power supply, in particular an autonomous power supply.
    According to the invention, this object is achieved with the wiper as defined above, in which the actuator has a speed of movement such that it is able to move the shoe between its retracted and deployed positions within a period of time. less than or equal to 1 second, preferably less than or equal to 0.5 seconds, and has a number of operating cycles before failure greater than or equal to 2,500,000.
    By replacing the old electric actuator with a powerful actuator at high speed of movement, the friction shoe moves very quickly between its two positions. Thus, a change in the power supply mode is possible dynamically. The pad can be extended or retracted even when the rail vehicle is traveling at its maximum speed.
    According to the invention, the wiper actuator has a high number of operating cycles before failure. Consequently, the wiper withstands a large number of retraction and deployment of the pad during the travel of the rail vehicle.
    According to preferred embodiments, the wiper according to the invention comprises one, more or all of the following characteristics, according to all the technically possible combinations:
    - The actuator includes an electric motor, preferably brushless;
    - The wiper includes an antenna for radio reception of an order to move the skate;
    - The antenna is arranged in the skate;
    - The mechanical system includes a set of elements for transforming a horizontal movement of an actuating member of the actuator into a vertical movement of the shoe;
    - The set of transformation elements comprises at least one piston cylinder; and
    - Each piston cylinder has a spring for biasing the shoe towards its deployed position.
    The invention further relates to a rail vehicle, in particular a tram, comprising at least one wiper having a speed of movement such that it is able to move the shoe between its retracted and deployed positions in a period of time less than or equal to 1 second. , preferably less than or equal to 0.5 seconds, and having a number of operating cycles before failure greater than or equal to 2,500,000.
    The invention also relates to a railway vehicle, in particular a tram, comprising at least one wiper as defined above.
    An embodiment of the invention will now be described in detail with reference to the single figure which shows a side view of a wiper according to the invention.
    The current collection wiper 10 is shown in the deployed state. It comprises an actuator 11, a current collection pad 12, a mechanical system 13 kinematically connecting the actuator 11 to the pad 12, as well as a frame 14 carrying the actuator 11, the pad 12 and the mechanical system 13.
    The mechanical system 13 comprises first and second deployment levers 13.1 and 13.2, first and second piston cylinders 13.3 and 13.4, first and second supports 13.5 and 13.6 of cylinders 13.3 and 13.4, a transmission fork 13.7, and a spindle 13.8. In one embodiment, the mechanical system 13 is composed of these elements. These are a set of elements for transforming a horizontal movement of an actuating member 11.2 of the actuator 11 into a vertical movement of the shoe 12.
    The actuator 11 comprises a casing 11.1. An actuating rod (or member) 11.2 is slidably mounted in an opening 11.3 of the actuator 11. The actuator 11 also has several inputs 11.4 serving for electrical supply and control. The actuator 11 is able to move the shoe 12 between a retracted position and a deployed position shown in the figure.
    The actuator 11 has a speed of movement such that it is able to move the shoe 12 between its retracted and deployed positions in a period of time less than or equal to 1 second, and preferably less than or equal to 0.5 seconds. The speed of movement of the actuator 11 is understood to mean the speed at which the actuation rod 11.2 moves between its extended and withdrawn position.
    In addition, the actuator 11 has a number of operating cycles before failure greater than or equal to 2,500,000. By an operating cycle is meant an ascent and descent of the shoe 12.
    To this end, the actuator 11 preferably comprises an electric motor, in particular brushless. Brushless electric motors have a short reaction time, are reliable and can be controlled by a control unit.
    A mechanism inside the casing 11.1 transforms a rotational movement of the electric motor into a translational movement of the actuating rod 11.2.
    The actuator 11 is arranged within an internal space 14.1 of the frame 14. More specifically, the actuator 11 has two pins 11.5 placed in bearings 14.2 of the frame 14.
    The actuating rod 11.2 is connected to a first end 13.81 of the drive pin 13.8. The other end 13.82 of the drive spindle 13.8 is pivotally mounted between two arms of the transmission fork 13.7. The transmission fork 13.7 is located between the two cylinder supports 13.5 and 13.6. It is connected to these in order to rotate them relative to the frame 14 between a low position (shoe 12 deployed) and a high position (shoe 12 retracted). The lower position is illustrated in the figure.
    One end E1 of the cylinder supports 13.5 and 13.6 is pivotally mounted on the frame 14. The other end E2 pivotally accommodates the heads of the cylinders 13.3 and 13.4.
    Each piston cylinder 13.3 and 13.4 has a cylindrical chamber C formed by an envelope V and receiving a compression spring R. Each spring R acts between a cylinder head and the piston P of a piston cylinder 13.3, 13.4. The rods T of the pistons P are pivotally connected to the deployment levers 13.1 and 13.2.
    One end of the deployment levers 13.1 and 13.2 is pivotally secured to the frame 14. The other end is pivotally attached to the shoe 12.
    Preferably, the skate 12 receives an antenna 12.1 for radio reception of an order to move the skate.
    Deployment and retraction of shoe 12 is carried out as follows.
    In order to retract the shoe 12 in the non-active position, starting from the deployed position shown in the figure, the actuator 11 is started up. This causes the actuating rod 11.2 to slide outwards from the housing 11.1. This movement is relayed to the transmission fork 13.7 via the drive spindle 13.8. Transmission fork 13.7 rotates cylinder supports 13.5 and 13.6 backward and upward in the figure. Consequently, the levers 13.1 and 13.2 are pulled upwards by the rods T of the piston cylinders 13.3 and 13.4. In this way, the shoe 12 is retracted.
    In order to deploy the shoe 12 in the socket outlet position, the actuator 11 is activated again. This time, the actuating rod 11.2 withdraws into the interior of the housing 11.1. The components of the mechanical system 13 then make the reverse movements, thus deploying the shoe 12. It will be noted that, when the shoe 12 abuts on a feed track during its deployment, the withdrawal of the actuating rod 11.2 continues. In this way, the pistons P go back inside the envelopes V and compress the springs R. The compressed springs R then urge the shoe 12 towards its deployed position and therefore towards the current supply track. This stress prevents a loss of contact between the shoe 12 and the feed track.
    It is possible to provide a control unit making it possible to control the behavior of the actuator 11, and in particular its speed of movement.
