Definitions

  • the present invention relates to a bogie comprising one or more several axles intended to equip a vehicle of the type with integral "low floor".
  • the passenger floor is typically about 350 mm above the rail level.
  • the low-floor vehicle is for example a vehicle tram type railroad.
  • DE-A1-44 19 362 discloses a motor bogie by rail wire for low-floor vehicle comprising a axle consisting of a load-bearing beam and receiving hubs carrying wheels.
  • the first architecture has the advantage, thanks presence of one motor per wheel, to have wheels independent in rotation which facilitate registration in bogie curve.
  • the first architecture has the major drawback generate a high cost of the motorization function (electrical equipment for motors, reducers ⁇ .
  • the first architecture also presents the disadvantage of not allowing to benefit from the principle mechanical self-stabilization of the railway axle brought by the taper of the wheel treads wedged on the same tree.
  • the second architecture has the major drawback too long overall axle dimensions to obtain a vehicle with an integral low floor.
  • the second architecture presents the disadvantage of not allowing positioning, in the body and to the right of the bogie, typically sixteen seats in the direction of travel, due to the longitudinal arrangement motors above the rails.
  • the second architecture also presents the disadvantage of not allowing either to benefit from the principle of mechanical self-stabilization of the axle railway brought by the conicity of the tread tables wheels wedged on the same tree.
  • the third architecture has the disadvantage of do not allow to have, in the box and the four bogie corners, access doors, due to layout of the engine outside the bogie and therefore under the body.
  • the third architecture also presents the disadvantage of not allowing a bogie to be produced fully motorized because it is necessary to install at least two access doors in the box near the bogie.
  • the transmission device of the movement of the motor to the wheels by rotating axle is placed too high to allow a floor vehicle to be obtained low.
  • an object of the invention is a bogie comprising one or more axles intended to equip a vehicle of the type with low integral floor, without the disadvantages bogies of the prior art and having a space requirement reduced overall longitudinal axle to allow a vehicle with an integral low floor.
  • the bogie comprising one or more axles intended for equipping a vehicle of the type with a full low floor is such as characterized below.
  • each wheel is driven by a motor-reduction unit attached to the wheel.
  • the four wheels are then independent in rotation.
  • each motor drives through two reducers two wheels located on the same side of the bogie.
  • the two wheels on the same side are therefore linked in rotation but there is independence in rotation of the wheels of the right line of the bogie with the wheels of the left yarn.
  • the motor drives via a shaft of cardan type a bevel gear pair housed in a reduction gear placed near one of the two wheels. Conical couple the movement is sent to one of the wheels directly by a flat gear train and on the second wheel by a second plane gear train identical to the previous one but via a connecting shaft located sufficiently low to allow a vehicle floor, for example at 350 mm above the level of the rail.
  • the axle motor drives a double gear train.
  • the engine drives a first stage from which the movement is distributed, via a second stage, directly on the wheel on the motor side and via a shaft transmission (passing under the lower part of the floor of body, for example 350mm) on the wheel opposite the engine.
  • the two axles are connected to each other by two spars, one of the ends of each of which is rigidly attached to one of the axles and the other end is attached to the other axle via a elastic joint whose role is to allow the bogie to absorb the track lefts.
  • Figures 5 to 8 show an axle conforming to the invention in a configuration with one axle motor.
  • Table 1 shows the different configurations possible provided by the axle according to the invention.
  • Table 2 shows the different configurations possible bogies created from two axles according to the invention.
  • the vehicle body Cv rests on the gantry-shaped bridge beam Pr, by means of the secondary suspensions Sp 1 and Sp 2 placed between the wheels vertically above the axle.
  • the beam of the bridge Pr receives bearings around which rotate the two wheel hubs Mo 1 and Mo 2 which carry the wheels Ro 1 and Ro 2 , as well as the brake discs.
  • a brake caliper And, hung on the bridge beam by the horns Cr1 and Cr2, covers the disc Di1.
  • the wheels Ro 1 and Ro 2 are not locked but bolted to the wheel hubs.
  • the wheels are therefore easily removable to be reprofiled without the need for a pit turn.
  • a second modularity of the axle according to the invention resides in that the interfaces for fixing the stops transverse, chassis beam and articulation of chassis on the bridge beam are identical so be able to place these organs indifferently according to the desired configuration: this allows in particular changing the length of the chassis beams that connect both axles to provide a short wheelbase bogie, medium or long.
  • the bridge beam is provided with a fixing range of low drive rod Bb and two fixing ranges of high drive rods Bh1 and Bh2, these two rods high drive being mounted for example if the axle according to the invention is used as an axle alone.
  • a connecting shaft Ar can be mounted on the same axis of rotation as that of the pinions Pi 1 and Pi 2 so as to link the two wheels of the axle in rotation.
  • a third modularity of the axle according to the invention then lies in that the two wheels of the axle can be independent or linked in rotation according to the absence or the presence of the connecting shaft.
  • the first reduction stage of the kinematic chain consists of a pinion Pj, wedged on the motor shaft, intermediate toothed wheels Ri and Rj, and the wheel toothed Rk mounted on the same shaft as the pinions Pi.
  • the assembly which constitutes the first reduction stage is mounted in an independent mechanical housing Ca bolted to the beam of the Pr bridge.
  • the traction motor Mt is flanged on this Ca housing.
  • a fifth modularity of the axle according to the invention then resides in that the carrying axle is convertible into drive axle by adding components, and the drive axle convertible into a carrying axle by removing organs.
