Problems solved by technology

However, the whole set of mechanism is relatively complex and heavy, and the reliability and maintainability need to be improved.
And once the electromagnetic clutch and other components that control the power output on and off fail, it will cause the wheels to not rotate normally during the landing phase, seriously threatening the safety of the aircraft

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with specific embodiments with reference to the accompanying drawings.

[0020] The wheel electric driving device of the present invention includes a coreless permanent disk motor installed on the inner wheel shaft of the wheel, and a motor drive controller installed on the landing gear. The ironless permanent disk motor installed on the inner axle of the wheel can be one or multiple ironless permanent disk motors connected in parallel. The following takes the installation of a single ironless permanent disk motor as an example, but it is also possible to provide a greater driving ability.

[0021] figure 1 It is a main structural composition diagram of the machine-wheel electric driving device of the present invention. As shown in the figure, the coreless permanent disk motor mainly includes the outer rotor 1 of the motor, the stator 2 of the motor, the outer bearing 3 of the motor and th...

Abstract

The invention discloses an airplane wheel electric driving device. The device comprises a coreless permanent magnet disc type motor installed on an axle (8) on the inner side of an airplane wheel (11)and a motor driving controller installed on an undercarriage, wherein a stator (2) of the coreless permanent magnet disc type motor is fixed to the axle (8), and an outer rotor (1) is connected withthe airplane wheel (11) and can drive the airplane wheel (11) to rotate or be driven by the airplane wheel (11); and the motor driving controller receives the aircraft driving control signal and drives the coreless permanent magnet disc type motor to rotate or disconnect power supply of the aircraft to the coreless permanent magnet disc type motor according to the aircraft driving control signal.According to the airplane wheel electric driving device, the coreless permanent magnet disc type motor can directly drive the airplane wheel, normal rotation of the airplane wheel is not affected, andthe airplane wheel electric driving device is simple, light and reliable.

Description

technical field [0001] The invention belongs to the technical field of aircraft design, and in particular relates to an electric drive device for a machine wheel. Background technique [0002] At present, the low-speed taxiing of the aircraft on the ground is generally achieved by pulling the wheels of the ground tractor or providing thrust by the engine running at a slow speed. The use of ground traction requires ground traction vehicles and related equipment, which increases the number of ground support equipment and the workload and time of preparation for taxiing, and is not easy to use in small spaces such as ship decks and hangars. The use of autonomous taxiing requires the engine to keep at a slow speed for a certain period of time, which will increase engine fuel consumption, increase pollution, reduce engine life, and lead to unstable taxiing, inaccurate stop, and increased wear and tear on brake devices and tires. [0003] In order to solve the above problems, rec...
