FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering. Aircraft undercarriage comprises first and second wheels on common axle. Drive assembly can be engaged with first and second wheels to make them run so that drive longitudinal passage direction is located in plane perpendicular to common axle of wheels. Besides, drive assembly comprises first motor to be engaged with first wheel via first wheel drive gearing and second motor to be engaged with second wheel via second wheel drive gearing. Note here that first and second tandem motors are arranged in direction of drive assembly lengthwise passage. Drive assembly can comprises motor and differential gearing, first and second gears. Motor can be engaged with first and second wheels via said gearing to be driven thereby. Output stage first gear can be engaged with first wheel axial gear engaged with first wheel for it to be drive thereby. Output stage second gear can be engaged with second wheel axial gear engaged with second wheel for it to be drive thereby. Output stage first and second gears are fitted on output stage common axle perpendicular to drive assembly lengthwise direction.

EFFECT: provision of required power for taxiing of large commercial aircraft.
