    • A drive unit (40) for an aircraft ground wheel (Ί 2) associated with a brake unit (30) for braking the ground wheel (12) is disclosed, 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). Further disclosed is a method of controlling such drive unit (40) in which the cooling system is driven by the driving motor (42) of the drive unit (40), the method comprising decoupling the driving motor (42) from the ground wheel (12) and increasing the rotational speed of the driving motor (42) to increase the amount of generated drive cooling air (54), when an operating condition of the ground wheel (12) and/or of the drive unit (40) is switched from a propulsion mode to a non-propulsion mode.
    • 公开了一种用于与用于制动研磨轮(12)的制动单元(30)相关联的用于飞机地砂轮(& 2)的驱动单元(40),所述驱动单元(40)包括驱动马达(42) 可与地面轮(12)连接; 以及至少包括驱动冷却单元(52)的冷却系统,所述驱动冷却单元构造成产生用于冷却所述驱动单元(40)的驱动冷却空气流(54)和制动器冷却单元(62,70,72,74) 通过从制动单元(30)吸入空气来产生制动冷却空气流(64)。 进一步公开的是一种控制这种驱动单元(40)的方法,其中冷却系统由驱动单元(40)的驱动马达(42)驱动,该方法包括将驱动马达(42)与地砂轮 12)和/或驱动单元(40)的操作状态被切换时,增加驱动电机(42)的旋转速度以增加产生的驱动冷却空气(54)的量 从推进模式到非推进模式。
