Definitions

  • the present invention relates to a maneuvering device fitted to a railway vehicle coach.
  • the displacement device When the displacement device is not necessary for the movement of the car, for example if the car is connected to a locomotive towing it, the displacement device must be completely disassembled, which leads to tedious operations.

  • the elongation system 60 takes the form of a cylinder.
  • the first part 90 for example takes the form of a piston while the second part 95 takes the form of a chamber in which the piston is able to slide.
  • the first 90 and second 95 parts being movable between them.
  • the first part 90 takes the form of a chamber and the second part 95 takes the form of a piston.

  • the piston 90 in the extended position of the elongation system 60, the piston 90 is out of the chamber 95. Conversely, in the compressed position the piston 90 is substantially entirely contained in the chamber 95.
  • the elongation system 60 therefore allows the passage of the roller 45 from the engaged position to the separated position, and vice versa.
  • the elongation system 60 is advantageously manual. In other words, the passage, of the elongation system 60, from the compressed position to the elongated position, and vice versa, results from a manual operation.
  • the elongation system 60 is automatic.
  • the passage, of the elongation system 60, from the compressed position to the elongated position, and vice versa, is automatic. Said passage is then for example controllable from the remote control system 65.

  • the operator 67 then settles down on the platform 30, equipped with the remote control 100.
  • the operator 67 then controls the speed of rotation and/or the direction of rotation of the motor 40, through his electric machine 70, from the remote control 100.
  • the rotational control of the electric machine 70 induces a rotation of the shaft 82, causing a rotation of the elements of the reducer 75, leading to a rotation of the axis 84 at a rotational speed lower than that of the shaft. 82.
  • the axis 84 being secured to the roller 45, the roller 45 is then also rotated.
  • the rotation of the roller 45 then allows the rotation of the wheel 35 by friction between the roller 45 and the wheel 35. More precisely, the rotation of the wheel 35 is due to the contact between the coating 86 and the wheel 35.
  • the rotation of the wheel 35 then involves the movement of car 10.
  • the operator 67 When the operator 67 wishes to stop the car 10, he activates the electric braking system 80, for example from the remote control 100.

  • the maneuvering device 25 makes it possible to move the car 10 and does not necessarily have to be dismantled when the car 10 is coupled to a locomotive towing it. Indeed, the elongation system 60 makes it possible to avoid dismantling the maneuvering device 25 to move the roller 45 away from the wheel 35.
  • an electric braking system 80 makes it possible to stop the car 10 during its movement, and therefore to maneuver the car 10 with precision.
  • the presence of the remote control system 65 and of the nacelle 30 allows the operator 67 to control the movement of the car 10 while maintaining a view of an environment in which the operator 67 and the car 10 are moving.
