Definitions

  • the invention consists of the headstock of a bimodal rail and road vehicle, provided with a rail type draw and buffing gears, which can retract in the vehicle's underframe, and with a device locking the headstock to the vehicle's underframe.
  • bimodal techniques are well-known as bimodal techniques or systems and the respective vehicles are generally defined as bimodal vehicles.
  • the ROAD-RAILER system consists of special semi-trailers (derived from the standard road semi-trailers) whose ends are put on special railway bogies in order to run on the rails.
  • the other bimodal system consists of a vehicle which can be used either with railway bogies or with road bogies.
  • draw and buffing gears must be retractable so that they do not interfere with manoeuvrability and the good working order of the vehicle in the road position.
  • the present invention a mobile headstock, fulfills this necessity.
  • the mobile headstock provided with draw end buffing gears, can slide in a horizontal plane, in the vehicle's frame along its longitudinal axle, by means of special guide bars. In this way the mobile headstock can assume two different positions:
  • the draw and buffing gears When the headstock is in the forward position (in the railway position) the draw and buffing gears are functional. In the same way when the headstock is in the backward position (in the road position) the draw and buffing gears will be kept within the maximum length allowed for semi-trailers and they will not obstruct the regular use of the semi-trailer.
  • the mobile headstock will be locked to the vehicle frame by means of two identical locking devices which will act on the two bars fixed to the headstock.
  • Each of these locking devices is composed of a rotary bushing permanently screwed on the inside of a coupling sleeve, by means of threads.
  • the coupling sleeve is fixed on the inside of the main cross bearer of the vehicle frame.
  • the rotary bushing On the inside, the rotary bushing is drilled and threaded lengthwise.
  • the threads are not on the overall circumference of the bushing's hole, but only on some land longitudinal sectors which alternate, in number, with some void longitudinal sectors.
  • the land longitudinal sectors have the same angular measure as the void longitudinal sectors.
  • the bar runs through the hole of the bushing. Along part of its length, congruous with the position ranges of the mobile headstock, it has a twin thread compared to the one thread of the bushing's hole.
  • a fraction of a turn of the rotary bushing equal to the angular measure of the void and land sectors, will bring the land sectors of the bushing's hole in front of the land sectors of the bar, thus screwing the respective threads.
  • the bar will not slide inside the bushing's hole. This will prevent the mobile headstock from moving away from the vehicle's underframe and will therefore lock it.
  • the land sectors are in front of the void sectors, the bar will be free to slide inside the bushing's hole. Now the headstock will be free to slide into the vehicle's underframe.
  • the necessary force for the sliding of the bars, and consequently of the headstock, is produced by two hydraulic rams, one for each bar.
  • the hydraulic ram acts on the bar by means of a fork which transmitts both a thrust and draw action on the bar.
  • this fork controls the rotation of the bushing and its safety catch, by means of poppet balls, in order to prevent accidental rotations.
  • This fork is provided with an ordinary escapement system, which acts on two fixed points of the vehicle's underframe, and which predisposes the fork's thrust or draw action on the bar.
  • FIG 3 represents the mobile headstock seen in perspective.
  • the mobile headstock (1) consists of a parallelepiped frame (2) made of the most appropriate materials and with the most appropriate manufacturing processes, so that they can take the stress prescribed by homologation regulations which rolling stocks are subjected to.
  • On the fore part of the headstock (1) the buffers (3) and the coupling hook (4) are placed.
  • On the sides it is equipped with special guide bars (5) which are interface the grooves (8) on the inner part, of the side sills of the frame (7). These allow the headstock to slide lengthwise.
  • On the rear part two bars (6) are fixed, which permitt the locking of the headstock, either in the forward position or the backward position. The locking occurs by means of the locking devices which are inside the main cross bearer (9) of the frame (7).
  • Figure 4 represents in perspective the mobile headstock (1) in the forward position, in the vehicle's frame (7). This is the railway position.
  • Figure 5 represents in perspective the mobile headstock (1) in the backward position, in the vehicle's frame (7). This is the road position.
  • Figure 6 represents, in the railway position, the mobile headstock (1), part of the vehicle frame (7), the hydraulic rams (16), seen in the plane level, the locking devices in longitudinal section.
  • Figure 7 represents the same elements as figure 6 in the road position.
  • Figure 8 represents in longitudinal section the locking device (10) which is composed of:
  • Figure 9 represents the cross section (W-W), indicated in figure 8, concerning the locking device (10).
  • W-W the locking device
  • the land threaded sectors of the rotary bushing (12) which screw to the land threaded sectors of the bar (6). In this case the bar is locked.
  • the cylindrical pins (13) of the rotary bushing (12) are intercepted by the shaped splines on the tines (15) of the control fork.
  • FIGS 18-19-20 illustrate in cross-section, the locking device (10) during the rotation of the bushing (12).
  • the rotation is provoked by the action of the splines of the tines (15), on the cylindrical pins (13) of the bushing.
