Definitions

  • the present invention relates to a bogie supported railroad car, notably for use in electrically driven trains for local traffic.
  • cars are carried resiliently on two fourwheel bogies located near the respective opposite ends of the car in such a manner that the car may pivot about a vertical middle axis of the bogie as well as about a horizontal, transverse middle axis of the bogie and to a certain extent also about a longitudinal middle axis thereof, whereby a certain mutual movability between the bogie and the car is required.
  • the use of such bogies involves various constructional and operational conditions, of which some may be designated drawbacks so far as they are found to be improvable.
  • the invention has the primary object of providing a bogie supported car having a bogie system, which is improved in several respects.
  • the car according to the invention is supported, immediately at each end thereof, on a central front block, which is rotable about a vertical axis and constitutes a bearing block for a pair of rearwardly and outwardly projecting wheel carrier arms, which are pivotable about a horizontal transverse axis and are each provided with a shaft bearing for an associated driving wheel and being in carrier connection with the respective car end bottom through a compression spring member.
  • a central front block which is rotable about a vertical axis and constitutes a bearing block for a pair of rearwardly and outwardly projecting wheel carrier arms, which are pivotable about a horizontal transverse axis and are each provided with a shaft bearing for an associated driving wheel and being in carrier connection with the respective car end bottom through a compression spring member.
  • the resilient means for carrying the car end on the rearwardly projection bogie arms may, according to the invention, be constituted by simple air cushion springs with associated shock absorbers, and by releaving the springs the weight of the car may operate a hydraulic cylinder serving as an actuator for the wheel brakes, whereby separate oil pumps for the brake system are made superfluous.
  • the air cushion springs may be designed as lateral stabi lizers, which will well allow for controlled relative turning of the bogie, but also make the bogie self-centering and prevent oscillations thereof.
  • the two bogie arms may be interconnected through a torsion bar, whereby the car may carry out resilient lateral tiltings with good bed support.
  • a new driving system comprising a water cooled electric motor, which is tightened directly to the car bottom with a noise reducing intermediate layer in a position on the opposite side of the two driving wheels relative the front block.
  • the motor is drivingly connected with the wheels through a flexible shaft driving on a wheel differential, the use of such a differential having been found to imply a surprisingly high reduction of the wear of the wheels.
  • the use of a water cooled motor is highly advantageous i.a. in that the car may be designed without the otherwise conventional, heavily dimensioned ventilation channels for supply of cooling air from above.
  • the car according to the invention is preferably provided with a simple emergency current generator driven by a small diesel or petrol motor, this being an installation which is much lighter than the accumulator batteries traditionally used for this purpose.
  • the car end as shown in a detailed manner in Fig. 1 has a car floor 2, which at the extreme car end has a vertical pivot pin connection 4 with an underlying bearing block 6 having a forwardly open hole 8 and an underlying receiver hole for a transverse pin 10.
  • the bearing block 6 is supported by a vertical pivot pin 12 received in a carrier bracket 14 depending from a rigid connection with the car floor or bottom 2.
  • the transverse pin 10 which is a torsion bar, is on each side of the block 6 connected with a rearwardly and outwardly projecting bogie arm 16 continuing rearwardly in a straight portion 18 having frontwise a lower bearing 20 for a driving wheel shaft 22 with associated driving wheels 24 and rearwise having an upper support surface 26 for an air cushion spring 28 arranged between this surface and the car bottom 2.
  • the air spring 28 is shaped as a short or low cylindrical member, the opposite plane sides of which are secured to the respective adjoining surfaces, such that the spring member or members will be resilient not only in the vertical direction, but also in transverse horizontal direction, whereby a suitable damping of the lateral pivotability of the bogie arms 16,18 about the vertical axis defined by the pivot pins 4,12 of the block 6 will be obtained.
  • shock absorber 30 Inside each of the air cushion springs is arranged a shock absorber 30.
  • a connector beam 32 carrying at its middle portion a hydraulic pressure cylinder 34 having its top end located slightly underneath the car bottom 2, such that it will be loaded with the weight of the car when the air is let out from the spring members 28.
  • the cylinder 34 constitutes a hydraulic pressure source for the brake system of the car, this system comprising conventional disc brakes with discs 36 and associated, non-illustrated spring biased braking cylinders.
  • the partial weight of the car resting on the actuator cylinder 34 will at any time be sufficient to actuate the wheel brakes whenever operated by the train pilot or by the pulling of an emergency brake lever, and a special pump for the brake system will thus be superfluous.
  • the braking is terminated by pumping air into the spring members 28.
  • the forwardly open hole 8 in the block 6 is used for receiving a horizontal carrier stub 38 on an automatic coupling block 40 of an otherwise conventional design.
  • this block may rotate on or about the stub 38, though in a non-illustrated manner the block 40 is spring biased towards a horizontal transverse position in its free condition, whereby the car is easy to couple together with a corresponding car, even if the cars are mutually laterally tilted.
  • the car end may carry out any required rotation in the horizontal plane relative the bogie 16,18,10 viz. about the pins 4 and 12, and that the car end will be resiliently supported on the driving wheels 24, viz. by the vertical pivotability of the bogie about the transverse bar against (or assisted by) the action of the spring members 28.
  • the bearing block 6 is provided with various shock absorb ing means in its connections to the respective adjoining elements.
  • the wheel shaft 22 is provided with a middle differential 42, which is connected with a driving shaft. 44 of an electric motor 46 incorporated in a liquid cooling box 48, which is provided with a flat top side, by which the motor box is mounted direct against the underside of the car floor 2, though through an intermediate layer of a shock and sound damping material.
  • the shaft 44 is of the flexible type, constructed e.g. in carbon fibre reinforced polyester, the shaft being connected with both the differential 42 and the motor 46 without the use of universal joints. Thus, the shaft 44 will establish a permanent driving connection during the occurring mutual movements between the differential 42 and the bottom anchored motor 46.
  • the motor cooling housing 48 is connected with an upper heat exchanger system (not shown), which comprises means for heat exchanging with both the outer air and the heating system of the car, such that during the wintertime the motor may contribute to the heating of the car.
  • an upper heat exchanger system (not shown), which comprises means for heat exchanging with both the outer air and the heating system of the car, such that during the wintertime the motor may contribute to the heating of the car.
  • Fig. 2 it is clearly shown that the driving wheels 24 may be located very near the ends of the car.
  • the total car length will hereby be reduced, inasfar as the support areas are located directly adjacent the car ends, and the associated car length reduction, as already mentioned, will be advantageous in several respects, particularly in enabling an increased car width and still a reduced weight of the car.
