Definitions

  • the invention relates to a single wheel drive unit.
  • Such a single wheel drive unit is known from DE-C-35 38 513.
  • This drive unit has a drive motor, the stator housing of which is designed as a wheel carrier for the individual wheel to be driven.
  • the drive motor is pivoted axially on the inside via vertical slide or roller bearings in a wheel guide rocker.
  • the stator housing of the drive motor is closed by a bearing plate. Due to the fact that the drive motor is only connected to the wheel guide rocker on one side, the stator housing is exposed to one-sided loading in its function as a wheel carrier. This can impair the wheel guidance, particularly when braking and accelerating, and can cause the drive unit to vibrate undesirably.
  • the object of the present invention is to provide a single-wheel drive unit in which the stator housing of the drive motor is significantly less loaded in its function as a wheel carrier.
  • the single wheel drive unit comprises a drive motor, the stator housing which is closed by end-side bearing plates is designed as a wheel carrier for the individual wheel to be driven, and the rotor shaft is mounted in the end plates via high-speed roller bearings is, the rotor shaft is placed axially on the outside via a planetary gear in driving connection with the single wheel.
  • a stator housing extension arranged on the gear-side end of the drive motor and extending in the axial direction, it is possible to fix the drive motor in the chassis on both sides, that is to say also with the gear-side end.
  • the drive motor is fastened to the chassis both with the axially inner end of its stator housing and with the axially outer end of its stator housing extension.
  • stator housing Due to the mounting of the drive motor on both sides, the stator housing is significantly less stressed in its function as a wheel carrier, since in the single-wheel drive unit according to the invention the stator housing extension also takes over the function of supporting parts. As a result, the occurrence of undesirable vibrations which impair the wheel guidance is reliably prevented in the drive unit.
  • a particularly compact embodiment is obtained with a single wheel drive unit according to one of claims 2 to 5, since in these cases the planetary gear is at least partially arranged in the stator housing extension.
  • the brake disc always advantageously runs at the wheel speed. As a result, significantly lower imbalances occur on the brake disc.
  • 1 denotes a drive motor for a single wheel 2.
  • the drive motor 1 has a stator housing 3 which is closed by end shields 4 and 5.
  • the rotor shaft 8 of the drive motor 1 is supported by high-speed roller bearings 6 and 7, respectively.
  • the stator housing 3 is designed as a wheel carrier.
  • the single wheel 2 is supported with its wheel hub 9 via wheel bearings 10 and 11 on the stator housing 3.
  • a stator housing extension 15 which extends in the axial direction, is arranged at the transmission end of the drive motor 1.
  • the stator housing extension 15 is advantageously connected to the stator housing 3 via at least two detachable screw connections.
  • the drive motor 1 is on both sides of the chassis, e.g. a U-shaped swing arm with two swing arms 16 and 17 attached.
  • the drive motor 1 is held at the axially inner end of the stator housing 3 and at the axially outer end of the stator housing extension 15.
  • stator housing extension 15 is advantageously also designed as a star-like planet carrier.
  • a planet gear 13 is mounted on each of the three Arms 18 of the planet carrier (only one arm visible in the drawing).
  • the bearing plate 4 is also designed as a planet carrier.
  • a planet gear 13 is mounted on each of the three arms 18, only one arm being visible in the drawing.
  • the gear-side end of the stator housing 3 is also designed as a planet carrier.
  • the planetary gear is enclosed by a gear housing 19, the ring gear 14 being secured against rotation on the gear housing 19.
  • the gear housing 19 thus rotates together with the ring gear 14 around the planet gears 13.
  • the rotational movement of the ring gear 14 is transmitted to the single wheel 2 by a non-positive connection between the gear housing 19 and the wheel hub 9.
  • a grounding contact 21 is arranged in the interior of the stator housing extension 15, the ground cable 22 of which is led out of the stator housing extension 15 via an opening 23.
  • the single wheel 2 can also be arranged turned.
  • the flange 24 of the single wheel 2 is then no longer on the side facing away from the planetary gear, but is arranged on the gear side.
  • the housing extension 15 is therefore no longer on the outside but on the inside.
