Electrically-driven undercarriage system and aircraft comprising same

The invention relates to an electrically-driven undercarriage system and an aircraft comprising the same.The electrically-driven undercarriage system is arranged at the bottom of the aircraft, the aircraft comprises a nose, a fuselage and a tail which are in sequential connection, the undercarriage system comprises a pair of main undercarriage mechanisms symmetrically arranged on two sides of the bottom of the body and a driving control mechanism electrically connected with the main undercarriage mechanisms respectively, each main undercarriage mechanism comprises a main undercarriage arranged at the bottom of the fuselage, a driving motor arranged on the main undercarriage, and a main wheel in transmission connection with the driving motor, and each driving motor is electrically connected with the corresponding driving control mechanism.Compared with the prior art, the electrically-driven undercarriage system has the advantages that the main wheel on each main undercarriage is utilized to drive the aircraft so as to improve takeoff performance of the aircraft; in addition, the undercarriage system has excellent steering capability and high automation level, takeoff noise is lowered, and a takeoff taxing means is provided for other aircrafts.
