Definitions

  • the invention relates to a single-axis drive according to the Preamble of claim 1.
  • Tatzlagerantriebe HÜTTE des Ingenieurs Taschenbuch, 28th edition, HÜTTE IV A Electrical Engineering, Part A, Berlin 1957, published by Wilhelm Ernst & Sohn, pages 188, 189.
  • the engine overhangs two paw bearings on the wheel axle between the driving wheels and is still by a pendulum support or a spring suspension held against the vehicle or bogie.
  • the pinion on the rotor shaft overhung and drives the driving axle via a large wheel with the appropriate translation.
  • Tatzlager drives are the ones that support the motor on the wheel axle Tatz bearings carried out separately from the axle bearings of the wheel axle.
  • the gear formed by the pinion and large wheel is from surrounded by a gear box.
  • This embodiment is technically at high torques and / or high gear ratios difficult to control, especially with one Motor rotor shaft of smaller diameter and when used a small pinion deflections of the rotor shaft occur, causing difficulty in meshing between the pinion and the big wheel.
  • GB-1 443 316 A is a single-axis drive for electrical Motor vehicles known in which the housing of the electrical Drive motor including an associated one Transmission gearbox on plain bearings with a bearing material are coated on both sides on the outer rings of the Bearing for the wheel axle is supported. Through one of these Torque support arranged opposite one another the drive is held on the vehicle or bogie. On Pinion arranged directly on the rotor shaft of the motor drives a large wheel sitting on the wheel axle. At this Arrangement is the wear on the bearings of the wheel axle and their shoulders very high, so that the well-known drive is at best suitable for lower performances. in addition there are difficulties in maintaining the bearings.
  • DE-91 15 647 U1 is an electric drive motor known with a transmission gear, which consists of a pinion on the rotor shaft and a large wheel sitting on the wheel axle exists, with pinion and large wheel in a gear housing are arranged.
  • the rotor shaft of the motor carries one provided on the output end of the shaft with the pinion, with a drive-side outer bearing of the rotor shaft with an outer rotor shaft bearing on the stub axle end is provided.
  • This rolling bearing is in a bearing bore one connected to the motor housing via an end plate End shield used.
  • a single-axis drive according to the preamble of claim 1 is also known from US 2 023 846 A.
  • the object of the invention is in a single-axis drive type mentioned in the limited performance, the high wear and difficult maintenance Avoid disadvantages and drive the transmission of high torques and / or when using large ones Improve translations.
  • the rotor shaft of the motor is mounted on the outside, i.e. in the arrangement of drive or A-side rotor shaft bearings - Pinion - rotor shaft - brush or B-side Rotor shaft bearings.
  • the advantage here is that compared to lower bearing forces occur with a cantilevered pinion, that a longer service life of the bearings is achieved and that due to less deflection of the rotor shaft a cheaper meshing results, which is gentle affects the transmission.
  • the motor is further provided that the drive side or A-sided paw bearings between the assigned A-sided Driving wheel and the transmission gear and the B-sided Tatzlager between the B-side engine end shield and the B-side driving wheel are supported on the wheel axle.
  • the arrangement of the Tatzlager is advantageous for the rotor shaft bearing customized. Because the drive-side peg bearing on the side facing the A-side drive wheel in the gearbox is arranged, there is a favorable power transmission from the outside pinion bearing over the Gear housing to the paw bearing and the wheel axle.
  • gear housing in the area of the meshing between pinion and large gear one Parting line provided so that there the gear housing parts are releasably attachable.
  • gearbox housing the A-side paw bearing and the large wheel through a receiving the A-side rotor shaft bearing A-side motor end shield for the complete housing be supplemented.
  • the second, B-side paw bearing in a B-side motor end shield is integrated.
  • the advantage here is that an independent Patzlagerenosusen and its fastenings to the motor housing omitted.
  • the B-side engine end shield for the arrangement of the B-side Tatzlager has a detachable half-shell.
  • the electric drive motor 1 is on the two Tatzlager 2, 3 supported between the drive wheels 5, 6 on the wheel axle 4, in this version the paw bearings 2, 3 directly sit on the wheel axle 4.
  • the wheel axis 4 is in the Axle bearings 35, 36 mounted.
  • the drive motor 1 includes a Rotor shaft 8, a rotor 27, a stator 28, a motor housing 22 and a drive or A-side motor end shield 18 and a brush-side or B-side motor end shield 11.
  • the rotor shaft 8 also carries a pinion 7 and is stored on the outside in the order that a stub axle stub 15 the A-side rotor shaft bearing 14 receives that an axle extension 13 of the rotor shaft 8 carries the pinion 7 that the rotor shaft 8 connects with the rotor 27 and that the B-side rotor shaft bearing 16 with the arrangement in the B-side Engine end shield 11 forms the engine end.
  • On the drive side of the motor 1 is the A-side motor end shield 18 to an end plate 21 with a bearing bore 20 for the A-side rotor shaft bearing 14 is formed, with between the pinion 7 and the motor interior 23 the shaft end 12 against the motor end shield 18 through a seal 24 is sealed.
  • As an external motor termination there is an A-side Bearing cover 25 or a B-side bearing cover 26 is provided.
  • a gear housing 10 is housed.
  • the output shaft end 12 of the rotor shaft 8 hollow, so that the axis approach 13, Pinion 7 and stub axle stub 15 formed pinion is rotatably connected to the rotor shaft.
  • the gearbox 10 is load-bearing and is along a parting line 17, which is preferably in the area of tooth engagement pinion and large wheel is located through the A-side motor end shield 18, which adds the A-side rotor shaft bearing 14 receives in its bearing bore 20.
  • the A-sided Tatzlager 2 is on the A-side drive wheel side arranged in the transmission housing 10. It is also provided that the A-side Tatzlager 2 and the A-side rotor shaft bearings 14 on the A-side driving wheel side and arranged lying in one plane in the gear housing 10 are.
  • the B-side engine end shield 11 is assigned Arrangement of the B-side paw bearing 3 a detachable bearing half-shell 19 on. From the view of Figure 2 it follows that the bearing half-shell 19 via a joint 29 against the B-side Motor bearing plate 11 is attachable.
  • the A-side paw bearing 2 on a collar of the wider wheel hub 31 of the large wheel 9 arranged.
  • This training results in a non-contact seal, e.g. a labyrinth seal, a desired, expanded radial space 32.
  • Due to the wider wheel hub 31 of the large wheel 9 is the bearing surface between the large wheel and the wheel axle 4 enlarged, so that higher torques can be transmitted.
  • 33 with a bearing cap is designated.
  • the rotor shaft 8 of the motor 1 is for driving of the large wheel 9 for the wheel axle 4 of the drive wheels 5, 6 of Rail vehicles and track-bound vehicles as pinion shafts 34 executed.
  • This training is characterized by the one-piece drive shaft.
