Landing gear of an aircraft and method for cooling an electric taxiing motor and brakes of such a landing gear

A landing gear of an aircraft comprising:

• at least one wheel;
• an electric taxiing system comprising an electric taxiing motor, said electric taxiing motor being configured to rotate said at least one wheel;
• a braking system comprising brakes configured to reduce a rotational rate of said at least one wheel;
• and
• a cooling system for cooling said electric taxiing motor and said brakes, the cooling system comprising ventilation means configured to mix a first air flow originating from said brakes and a second air flow originating from outside said landing gear to create a mixed third air flow, and configured to ventilate said electric taxiing motor with the mixed third air flow, wherein said ventilation means comprise a ventilation wheel configured to suck said mixed third air flow and a motor configured to rotate said ventilation wheel.
