DRIVE UNIT FOR AIRCRAFT LANDING GEAR WITH INTEGRATED COOLING

摘要

A drive unit for an aircraft ground wheel associated with a brake unit for braking the ground wheel includes: a driving motor drivingly coupleable to the ground wheel; and a cooling system including at least a drive cooling unit configured to generate a drive cooling air stream for cooling the drive unit and a brake cooling unit configured to generate a brake cooling air stream by sucking in air from the brake unit. A method of controlling such drive unit in which the cooling system is driven by the driving motor of the drive unit includes: decoupling the driving motor from the ground wheel and increasing the rotational speed of the driving motor to increase the amount of generated drive cooling air, when an operating condition of the ground wheel and/or of the drive unit is switched from a propulsion mode to a non-propulsion mode.

1. A drive unit (40) for an aircraft ground wheel (12) associated with a brake unit (30) for braking the ground wheel (12), the drive unit (40) comprising:
a driving motor (42) being drivingly coupleable to the ground wheel (12); and a cooling system including at least a drive cooling unit (52) being configured to generate a drive cooling air stream (54) for cooling the drive unit (40) and a brake cooling unit (62, 70; 72, 74) configured to generate a brake cooling air stream (64) by sucking in air from the brake unit (30).
