    High speed train driver
    The present invention relates to a high-speed train power train, in particular for passenger transport, of the type comprising a body and at least one traction motor for said body, said body comprising a roof and a floor, the at least one motor of traction being disposed under said floor; the body further comprising: a dynamic brake arranged in the upper part of said body; and a first device for ventilating said dynamic brake; the box also comprising: electrical equipment for controlling at least one traction motor; and a second device for ventilating said electrical equipment.
    The invention is particularly applicable to passenger transport. A high-speed train includes one or more drive trains, most often one at each end of the train, and a number of passenger cars.
    In current high-speed trains, the ventilation of the electrical equipment of the power cars is ensured by ventilation holes in the side walls of said power cars. The movement of the train generates a flow of air which cools said electrical equipment. However, such a ventilation system exposes electrical equipment to outside dust, humidity, and even snow.
    In order to remove the side openings, it is known to arrange the air inlets and outlets on the roof, as for example described in the document FR3014396 in the name of the Applicant.
    However, the cooling device described in this document requires a minimum installation length. It is therefore incompatible with the realization of a short motor.
    In addition, the cooling of certain equipment, such as the dynamic brake, leads to the rejection of air at a high temperature. The presence of this hot air can affect the cooling of certain other equipment of the powerplant.
    The present invention aims to solve these problems. To this end, the invention relates to a high-speed train power train of the aforementioned type, in which: the first ventilation device comprises a first air intake duct, forming a closed duct between an inlet and an outlet ; said inlet and outlet being located respectively at a first and a second air intake vents located on the roof of the box; the second ventilation device comprises a second air intake duct, forming a closed duct between an inlet and an outlet; said inlet and outlet being located at the level, respectively, of a third air inlet mouth located on the roof of the body and a fourth air inlet mouth located under the floor of the body; and each of the first and second ventilation devices includes a fan disposed between the inlet and the outlet of the first and second ducts, respectively.
    According to other advantageous aspects of the invention, the powerplant comprises one or more of the following characteristics, taken in isolation or in any technically possible combination:
    - The box also comprises at least a third ventilation device, said third ventilation device comprising a third air intake duct, forming a closed duct between an inlet and an outlet, the inlet of the third duct being disposed on the roof of the body;
    - The third ventilation device comprises a third electric fan arranged in the third duct;
    - The box also comprises at least a fourth ventilation device, said fourth ventilation device comprising a fourth air intake duct, forming a closed duct between an inlet and an outlet, the inlet of the fourth duct being disposed on the roof of the body;
    - The fourth ventilation device comprises a fourth electric fan arranged in the fourth duct;
    - the body includes a technical room receiving electrical and / or electronic equipment from the powerplant; and the outlet of the third sheath is arranged inside said technical room;
    - the outlet of the third sheath is open under the floor of the body, opposite the at least one traction motor;
    - the high-speed train driver further comprises an electric transformer connected to at least one traction motor; said transformer being connected to a radiator located under the floor of the body; the outlet of the second sheath of the second ventilation device opening out opposite said radiator.

    The lower stage 28 of the technical compartment 24 comprises a central corridor 56. Advantageously, said central corridor has a width along Y of between 500 mm and 750 mm, preferably equal to approximately 750 mm. This width is determined to allow comfortable passage for an operator, without significantly limiting the volume available for the powerplant equipment.
    The lower stage 28 further comprises two cooling towers 60, located on either side of the central corridor 56 and extending substantially along Z. The cooling towers 60 are substantially arranged above the electrical transformer 18. The cooling towers 60 are visible in section in FIG. 2.
    Each cooling tower 60 has an outer casing 62 which extends from the floor 20 to the ceiling 26, fluidly isolating said tower 60 from the atmosphere of the central corridor 56.
    Inside each outer casing 62 is received a traction box 64. Said traction box 64 comprises electrical and / or electronic equipment for controlling the traction motors 16, 17.
    The lower stage 28 further comprises at least a second ventilation device 66, associated with a cooling tower 60. In the embodiment of Figures 1 to 3, each cooling tower 60 is associated with a second ventilation device 66 separate. A single second ventilation device 66 will be described below.
