Definitions

  • the invention relates to a rail-bound electric traction vehicle, in which the electric traction motor drives a drive wheel via gears, both drive wheels being fastened on separate shaft sections, one of which runs out to a shaft journal, while the other has a hollow shaft stub, which, meshing and guided against one another , form a driving axis.
  • Such a locomotive is known from DE-C-4 96 993.
  • the torque generated by the electric traction motor is given in the known locomotive in the usual way via the pinion on the large wheel and this is designed inside as a differential gear, so that on the one hand the torque is transmitted to the hollow shaft and on the other hand to the shaft journal, each one of the driving wheels.
  • Both axle halves interlock only for the purpose of axial locking, which is why an inner thrust bearing is provided in combination with an inner shoulder bearing. This is to prevent harmful effects on the differential gear.
  • the two axle halves are supported independently of each other.
  • the axle halves with the hollow shaft stub are supported by means of a journal bearing, while the other axle half, which form the middle shaft journal, is only supported outside the hollow shaft in the differential gear.
  • the bearings must absorb the full speed of the axle halves, which is why roller bearings are used.
  • the use of a differential gear is very complex.
  • EP-A-0 005 777 discloses a rail-bound electric locomotive in which the two driving wheels associated with a driving axle are each driven separately by an electric traction motor. Each drive wheel is attached to a hollow shaft and the two hollow shafts are each mounted on a common, rigid axle. This results in a mechanical decoupling of the two drive wheels and the slippage of one of the wheels that otherwise occurs when cornering is avoided.
  • the full speed of the drive wheels is applied to the mounting of the hollow shaft on the rigid axle, which necessitates the use of grease or oil lubricated bearings, in particular roller bearings.
  • the outer diameter of the hollow shafts must be selected to be relatively large. Furthermore, there is no suspension with the large wheel or the drive motor, which worsens the running properties.
  • CH-A-4 52 584 also describes a mechanically decoupled axle, the wheels of which are arranged on separate shaft sections.
  • the one shaft section that carries one wheel consists of a hollow shaft that surrounds the other shaft that carries the other wheel. Since this is a pure running axle, in which no torques are transmitted to the wheels, the hollow shaft is supported on the other shaft via plain bearings.
  • the present invention has for its object to make the mechanical decoupling of the drive wheels in a rail-bound electric traction vehicle so that their space requirements and maintenance are low.
  • the shaft journal is mounted via slide bearings within the hollow shaft stump and the electric traction motor is designed as a double-rotor motor, of which the independent rotor shafts are each connected to a shaft section of the drive shaft.
  • These plain bearings between the two shaft sections, i. H. between the shaft journal and the hollow shaft stub is in each case loaded only by slight differences in speed, namely only by those that would correspond to the slip occurring when cornering or due to different wear.
  • the load on the plain bearings is very low and they can be designed accordingly for little space and maintenance.
  • the given mechanical decoupling is not short-circuited by the rotor shaft of the electric traction motor, since the latter is designed as a double-rotor motor and thus has two mutually independent rotor shafts, one of which drives a shaft section via the transmission.
  • Such a mechanically decoupled driving axle of a traction vehicle can be used both with single-axle drives and with two-axle drives.
  • a two-axis longitudinal drive it is recommended that two longitudinal double-rotor motors each drive one shaft section of the two drive axles and that the double-rotor bearings are mounted one inside the other.
  • the electric traction motor 1 is designed as a double-rotor motor, ie the two rotors, which are mounted independently of one another in a manner not shown and each drive a pinion 2 or 3, lie within a common stator and are therefore subject to common excitation.
  • Each pinion 2 or 3 drives a shaft section 6 or 7 of the drive shaft 8 via the large wheel 4 or 5.
  • the traction motor 1 is mounted on both shaft sections 6, 7 with the aid of paw bearings 9 and 10.
  • a drive wheel 11 or 12 is attached to each shaft section 6 or 7 of the drive shaft 8.
  • the shaft section 6 terminates in a shaft journal 13 which projects into the interior of the hollow shaft stub 14 which the shaft section 7 has.
  • the two dry-lubricated slide bearings 15 serve to center the shaft journal 13 in the hollow shaft stub 14. Only the slip speed resulting from cornering or different wear of the drive wheels 11 and 12 is present, so that the slide bearings 15 are loaded only to a very small extent .
  • This special design of the drive axle 8 achieves mechanical decoupling of the two drive wheels 11 and 12, as a result of which the noise which occurs during operation of the locomotive is reduced and the maintenance interval for equalizing the drive wheel diameters can be increased.
  • Fig. 2 shows the use of such a mechanically decoupled drive axle 8 in a two-axis longitudinal drive.
  • a pair of double-rotor motors consisting of two double-rotor motors located in a common stator 16 with a common end plate 17, serves as the electric traction motor for driving the two mechanically decoupled adjacent drive axles 8. This saves weight and can produce the laminated cores in a single cut.
  • the two rotors 18 and 19 or 20 and 21 of each double-rotor motor are mounted one inside the other via a shaft journal 22 or 23. This also provides mechanical decoupling for the adjacent shaft sections 6 and 7 of the adjacent drive axles driven by each double-rotor motor.
  • each double-rotor motor drives a large wheel 26 arranged on a shaft section 6 or 7 via a pinion 25 designed as a bevel gear.
  • the common for each drive shaft 8 gear housing 27 is mounted on roller bearings 28 on the two shaft sections 6 and 7.
  • the rotors 18 and 20 of the double-rotor motors lying next to one another are given an opposite direction of rotation.
  • a large wheel 26 would have to be mounted rotated by 180 °, which would result in completely identical gears.
  • the mechanically decoupled drive axles 8 can be used with all longitudinal drive principles with a double rotor motor, even if they have a different construction than that shown in the exemplary embodiment.
  • the drive masses of the electric traction vehicle can only be cushioned to a limited extent by providing appropriate rubber elements in the drive wheels themselves.
  • the large wheels 26 are not mounted on the shaft sections 6 or 7 of the drive shaft 8 themselves, but rather on a hollow shaft 29 or 30, which surrounds the drive shaft 8 with play.
  • the hollow shaft 29 carries a shoulder 31 of smaller diameter, which projects into the interior of the hollow shaft 30 and is supported there with bearings 32.
  • These bearings 32 are designed as dry-lubricated, maintenance-free plain bearings, since the relative speed between the two hollow shafts 29 and 30 is also very low.
  • each hollow shaft 29 or 30 is connected to the associated shaft section 6 or 7 via a centering and elastic coupling 33.
  • the clutch 33 is shown as a rubber ring spring clutch, but there are also other flexible couplings, such as. B. handlebar couplings. As a result of the presence of these clutches 33, the mass of the hollow shafts 29, 30 with the drive parts, not shown, is primarily cushioned with respect to the drive axle 8 with the drive wheels 11 and 12.
