摘要
起落架机轮就是飞机在地面停放、滑行、起降滑跑时用于支持飞机重量、吸收撞击能量的飞机部件。简单地说，起落架就像汽车的车轮，它能够消耗和吸收飞机在着陆时的撞击能量。概括起来，起落架机轮的主要作用有以下四个：承受飞机在地面停放、滑行、起飞降落滑跑时的重力；承受、消耗和吸收飞机在着陆与地面运动时的撞击和颠簸能量；跑与滑行时的制动；滑跑与滑行操纵飞机。
为适应飞机起飞、着陆滑跑和地面滑行的需要，起落架的最下端装有带充气的轮胎的机轮。为了缩短着陆滑跑距离，机轮上装有刹车或自动刹车装置。因此起落架机轮对于飞机至关重要。
本文主要阐述的是飞机的机轮介绍，机轮的勤务工作，以及如何节省机轮的使用。

ABSTRACT
The landing gear wheel is parked in the ground plane, taxi and landing runway used to support the aircraft weight, absorb the impact energy of aircraft parts. In simple terms, the gear is like a car wheels, it will burn and absorb the airplane in landing impact energy. In summary, the main effect of the gear wheel has the following four: aircraft parked on the ground, slide, under the gravity of the land and take off the taxi; bear, consumption and absorb the airplane in landing and ground motion when the impact and turbulence energy; run and slide when braking; taxi and sliding control the aircraft.
In order to adapt to take off, landing, and the needs of the taxi, the landing gear of the bottom is equipped with wheel with inflatable tires. In order to shorten landing running distance, mounted on the wheel braking or automatic brakes. So the gear wheel is vital for the plane.
This paper mainly introduces the aircraft tire, tire service work, and how to save the use of the wheel.
