A320飞机轮胎检查维护标准
本文参考空客AMM手册和服务信函，介绍了A320系列飞机轮胎检查维护标准。中英双语，图文并茂，希望有用。1. Normal wear正常磨损An equal wear of the tread shows that the tire maintenance was correct during the tire life.胎面的均匀磨损说明在轮胎寿命周期内得到了正确维护http://mmbiz.qpic.cn/mmbiz_png/KtqcNoGOuN9OegoZcq4DZxlsJ8TPRCwpTDFYcf5sOia8xGahpoaTpjOSxO2OUL6IobASftPp3BX7taxhBczEhibw/0?wx_fmt=pngAt the main base (or maintenance base), the tire shall be removed from aircraft if:当飞机在基地站，轮胎必须被更换，如果：[*]The tread wear is at the bottom of groove at one or more points；
[*]胎面一处或多处沟槽磨平；
[*]You can see the reinforced ply (bias tire) or the protector ply (radial tire) at one or more points of the tread surface.
[*]胎面一处或多处可见加强层（斜交胎）或保护层（子午胎）
NOTE
TIRES HAVING REACHED THE ABOVE LIMITS SHOULD BE REPLACED IMMEDIATELY. 轮胎超限需要立即更换。A SINGLE RETURN TO BASE (*) FLIGHT IS PERMITTED IF THE AIRCRAFT IS IN OUTSIDE STATION. 如果飞机在外站，一个返回基地站(*)的单向航段是允许的。(*) Any station where a spare wheel is available.任意有轮子的航站
2. Uneven wear不均匀磨损
Usually, under-inflation (inflation pressure less than 90% of the nominal pressurecan cause:通常，充气不足（压力小于规定压力的90%），可能造成：
[*]too much tread shoulder wear,
[*]胎肩磨损严重，
[*]high deflection of the tire, with subsequent heat build-up which can cause important internal tire damage.
[*]轮胎变形严重，导致胎内热量积压，这将造成严重胎内损伤(剥离、脱/甩胶等)。

[*]cause too much wear on the center of the tire tread,
[*]造成胎面中部磨损严重
[*]increase the risk of Foreign Object Damage (FOD) to the tire.
[*]增加外来物损伤轮胎风险
http://mmbiz.qpic.cn/mmbiz_png/KtqcNoGOuN9OegoZcq4DZxlsJ8TPRCwpKPg3MYShWtDMlJDsI8qoBsBJc2sWx1fo6bsgMvgZ77ntrlEbxBMSSQ/0?wx_fmt=png
NOTE
TIRES HAVING REACHED THE ABOVE LIMITS SHOULD BE REPLACED IMMEDIATELY. 轮胎超限需要立即更换。A SINGLE RETURN TO BASE (*) FLIGHT IS PERMITTED IF THE AIRCRAFT IS IN OUTSIDE STATION. 如果飞机在外站，一个返回基地站(*)的单向航段是允许的。(*) Any station where a spare wheel is available.任意有轮子的航站
3. Overspeed超速On A318, A319, A320 and A321 aircraft, the maximum operation speed is 225 MPH (195 KTS)(Ground Speed).A320系列飞机，最大操作速度是225迈(195节)(地速)。If a tire overspeed occurs during take-off or landing, Remove all the wheels immediately. Send the tires back to the tire manufacturer.如果飞机轮胎在起飞或着陆期间超速，必须更换所有轮子，并送回制造商。
NOTE
There is no tolerance. 没有容限，必须更换
4. Tread damage胎面损伤(1) Flat spots点状磨平Flat spot are caused by locking of the wheel during braking, hard touch down or sudden steering maneuvers (for the NLG tires).点状磨平是由刹车锁死、重着陆、突然转向(前轮)造成的。http://mmbiz.qpic.cn/mmbiz_png/KtqcNoGOuN9OegoZcq4DZxlsJ8TPRCwpWXGQcq0ya3ogolianfjnNraOGGkaY3zGhMU1SYCIuibrcGicGFfF9iccYQ/0?wx_fmt=pngThe tire shall be removed from aircraft if the flat spot reaches the reinforcing ply (bias tire) or the protector ply (radial tire).如果磨平点到达加强层（斜交胎）或保护层（子午胎），轮胎需要更换。
NOTE
IF THE FLAT SPOT DOES NOT REACH THE ABOVE-MENTIONED LIMIT, IF THERE IS SUFFICIENT GROOVE DEPTH IN THE WHOLE FLAT SPOT AREA, IF THERE IS NO INCIPIENT SEPARATION AND IF VIBRATION IS NOT DETECTED DURING ROLLING, THE TIRE CAN REMAIN IN SERVICE.如果磨平点没有超限，如果磨平处沟槽足够深，如果没有分层迹象，且如果行使过程中没有震动，轮胎可以继续使用
(2) Peeled rib胎肋剥落Usually starts with a cut in the tread and results in a circumferential delamination of the tread rib away from the tire carcass.胎肋丢失通常开始于胎面割伤，导致胎肋从胎体帘布层周向分层http://mmbiz.qpic.cn/mmbiz_png/KtqcNoGOuN9OegoZcq4DZxlsJ8TPRCwpw42CbNBJpEOOvxw2Ou6cxGjxKygwAymHicwMBdRBmwVZicc6tlqvibIAg/0?wx_fmt=pngRemove the tire immediately. 立即更换。(3) Tread rubber reversion胎面褶皱
Tread rubber reversion is generally caused by wheel locking on wet or ice covered runways. The affected area is similar in shape to a flat spot (oval), but the rubber appears to be melted.胎面橡胶还原通常是在湿滑、结冰跑道上轮子抱死造成的。影响区域呈椭圆形斑块，橡胶呈现融化状态。http://mmbiz.qpic.cn/mmbiz_png/KtqcNoGOuN9OegoZcq4DZxlsJ8TPRCwp7BF1xl2IyecN4ZaZ917zBNGGI7nJb9iabemETrKBicTjzZzcscJ1Wficw/0?wx_fmt=pngThe tire shall be removed from aircraft if:更换条件：
[*]the reinforcing ply (bias tire) or the protector ply (radial tire) is reached,
[*]见加强层（斜交胎）或保护层（子午胎）,
[*]shimmy or unbalance problem are experienced
[*]出现震动、平衡问题
(4) Thrown tread胎面丢失Thrown tread is a total or partial loss of tread that lets you see the carcass plies. Early signs of tread separation can occur in the form of tread bulges, local uneven wear (depression) or local tread/sidewall rubber split.胎面丢失是胎面全部或部分丢失，以致你能看到胎体帘布层。胎面分层早期迹象，以胎面鼓包、局部不均匀磨损、局部胎面胎侧橡胶开裂的形式发生。http://mmbiz.qpic.cn/mmbiz_png/KtqcNoGOuN9OegoZcq4DZxlsJ8TPRCwpMsCqqw62n3iaTnHsESYiczAW6bUDib8UO6JwGOxxyHDveySCmto1HjzxQ/0?wx_fmt=pngRemove the tire immediately. 立即更换。
NOTE
Get pieces of tread from the airport authorities and send them back to homebase so that the vendor can make an analysis
碎片送回供应商分析If the tire is still inflated after the aircraft is parked, it is necessary to wait three hours (for tire cooling) before you record the pressure.Then, deflate the tire before removal of the wheel assembly.等待轮胎降温，放气后，方可更换
(5) Tread cuts胎面割伤
Foreign objects that are present on the runway, taxiway and parking areas cause cuts to the tires.出现在跑道、滑行道、停机坪的外来物，造成轮胎割伤。http://mmbiz.qpic.cn/mmbiz_png/KtqcNoGOuN9OegoZcq4DZxlsJ8TPRCwpovxN2eb1oaiaMvDawhbxKFelnBgqf0LbS6deAeHnuLPZzkqplk1BoKA/0?wx_fmt=pngThe definition of cut limits is complex, it is based on the service experience of each vendor. Because of the different technologies and tire constructions, damage tolerance can be different for each manufacturer.割伤限制标准比较复杂，这基于每一个供应商使用经验。因为对于不同制造商，不同技术和轮胎构造，损伤容限可能不同。Refer to the relevant vendor’s manual for details. In the absence of specific cut limits in documentation, the tire shall be removed from the aircraft if:详情参考相关供应商手册，如果文件中没有确切割伤限制，轮胎更换条件如下：
