Definitions

  • the wheel hub motor is a motor that does not drive the axle on which the wheel hub sits but drives the wheel itself in the area of the wheel hub.
  • the wheel hub is the central rotating part of the wheel.
  • the wheel hub motor can lie radially inside the wheel hub and drive the wheel hub from the inside or even lie next to the wheel hub and drive the wheel hub, for example on the rim from the outside.
  • the drive of the wheel or the wheel itself may have a freewheel that should be lockable in the case of a reversible drive to allow the reverse drive.
  • the freewheel prevents parts of the drive unit from being unnecessarily rotated by the wheels when starting or landing.
  • a coupling device for coupling and decoupling of the wheel can be provided by the engine. In the decoupled state, the wheel is then free-running in both directions.
  • the power source for the motor 5 sits in the fuselage or in its attachments (eg wings, tail units, pylons, etc.). Particularly in the case of an electric motor, the power supply preferably takes place independently of the main engines of the aircraft, for example via the on-board APU ("auxiliary power unit") . If it is a hydraulic engine, it can be connected to an already existing general hydraulic system of the aircraft, whose hydraulic pump can in turn be powered by the on-board APU.
  • auxiliary power unit auxiliary power unit
  • the wheel hub motor 5 may also be located radially inside the wheel hub.
  • the axis on which the wheel hub runs be designed as a stator and the associated rotor be integrated into the wheel hub.
  • the wheel hub motors 5 of the two wheels 2 can be controlled separately, so that if necessary, a differential effect is technically feasible.
  • a mechanical differential gear can be omitted.
  • the use of a separate, large and heavy mechanical transmission can be dispensed with, since hydraulic motors and electric motors can provide very high outputs and torques despite a small overall volume.
  • the nose landing gear and the main landing gear can be equipped with appropriate drives.

Abstract

Le moteur (5) destiné à entraîner les roues (2) d'un train d'atterrissage d'avion, en particulier d'un train d'atterrissage avant, est monté dans la base (7) de la jambe de train (1), ou est intégré sous forme de moteur de moyeu dans le moyeu de roue ou la jante (3). De préférence, le moteur est réalisé sous forme de moteur hydraulique ou de moteur électrique, et il est alimenté en énergie par l'intermédiaire de la jambe de train. On peut se passer d'une transmission lourde et coûteuse entre le moteur (5) et la roue (2).
