汽車正時皮帶，怎樣才能知道該換了？即根據廠家提供的車主手冊，按照上面給出的要求，結合車輛的實際使用時間和實際行駛里程，檢查正時皮帶是否需要更換！早些年很多廠家給出的更換週期基本都是三年或者6萬公里。
近兩年，隨著我國製造技術的不斷提升，越來越多的車企將正時皮帶的更換週期延長至9萬公里左右，甚至12萬公里。這個具體週期還是要參考原廠保養手冊！那麼什麼時候應該更換正時皮帶呢？車主們經常可以聽到各種不同的爭論。
其中一個說法更能為大多數車主所接受，即每四年或八萬公里更換一次。那麼這個說法是絕對正確的嗎？其實沒有必要。因為一些使用壽命比較長的車型，由於當時製造工藝的限制，同步帶的使用壽命真的很短。
但是隨著科技的發展，近年來模型製作工藝突飛猛進，同步帶的使用壽命得到了極大的延長。例如，大眾EA211發動機的使用壽命達到了18萬公里。服務手冊對於同步帶的使用壽命有明確規定，一般為3年或6萬公里。
當然，有些車型的更換里程為6萬-10萬公里，也有終身不需要保養的皮帶或鏈條。建議檢查時機：5萬公里前幾乎不檢查，5萬公里後定期檢查。公里。檢查方法遵循以下說明。方法來做到這一點。
正時皮帶是橡膠零件。隨著發動機工作時間的增加，正時皮帶及正時皮帶張緊器、正時皮帶張緊器、水泵等正時皮帶附件會磨損或老化。因此，對於任何裝有正時皮帶的發動機，廠家都會有嚴格的要求，在規定的週期內定期更換正時皮帶及配件。
更換週期因發動機結構而異。1萬至10萬公里之間應更換，具體更換週期以車輛保養手冊中的說明為准。正時皮帶一般認為8萬公里就更換了。即使你的車上有正時皮帶，如果它壞了，你也無法更換它。
因此，當總里程達到8萬時，建議考慮更換。但在這些部件出現故障之前，您很可能會感覺到車輛產生異響、異響等，究竟是皮帶輪上的軸承滾珠引起的，還是油囊和油囊不潤滑引起的？因乾燥和縫隙變化引起的沙沙聲。
聲音取決於軸承的碰撞和擠壓，顫動是由軸承間隙的變化和老化引起的皮帶變形引起的。如果駕駛時電池故障燈亮起，請立即停車並呼叫道路救援。只有兩種可能，一種是發電機出現故障，但一般來說，發電機屬於不可使用的部件。
出現故障的可能性不是很大。這時應檢查正時皮帶是否磨損或脫落。由於正時皮帶脫落，汽車的發電機不能正常工作，汽車的電源失去驅動力，電池故障燈就會出現。一般來說，正時皮帶最好每3萬到4萬公里檢查更換一次，不要等到出了問題才更換。
正時鏈取決於里程和使用情況。一般私家車的續航里程只有20萬公里，目前的預計里程估計在40萬公里左右。鏈條使用時間長了會被拉伸變形，導致氣門機構運行出現偏差，進排氣門開閉稍有不準確，汽車加速不良，發動機運轉不穩。
如果您有耐心，可以閱讀您的手冊，瞭解製造商的規定。如果你不想看書，那麼等車子跑了五六年，再檢查一下皮帶的延長度。比較容易看出它沒有舊或損壞。如果看到有裂痕，不要拖延，儘快更換，因為這關係到車內人員的生命安全，切不可大意。
How do I know when it's time to change my timing belt? According to the owner's manual provided by the manufacturer, check whether the timing belt needs to be replaced according to the requirements given above, combined with the actual usage time and actual mileage of the vehicle! In earlier years, many manufacturers gave the replacement cycle is basically three years or 60,000 km.
In recent years, with the continuous improvement of manufacturing technology in China, more and more car companies have extended the replacement cycle of timing belts to around 90,000 km, or even 120,000 km. This specific cycle should still be referred to the original maintenance manual! So when should you change your timing belt? Owners can often hear different arguments.
One of the more accepted arguments is that it should be changed every four years or 80,000 kilometres. Is this absolutely correct? In fact, it is not necessary. Some of the longer-lasting models have a really short service life due to the limitations of the manufacturing process at the time.
However, with the development of technology and the rapid advancement of model making techniques in recent years, the service life of timing belts has been greatly extended. For example, the VW EA211 engine has a service life of 180,000 km. The service manual specifies a service life of 3 years or 60,000 km for timing belts.
Of course, some models have a replacement range of 60,000 - 100,000 km, and there are also belts or chains that do not require maintenance for life. The recommended time for inspection: hardly ever before 50,000 km, regularly after 50,000 km. The recommended inspection schedule is as follows Follow the instructions below. To do this.
Timing belts are rubber parts. As the engine works longer, the timing belt and timing belt tensioner, timing belt tensioner, water pump and other timing belt accessories will wear out or deteriorate. Therefore, for any engine fitted with a timing belt, the manufacturer has strict requirements to replace the timing belt and accessories on a regular basis within the prescribed intervals.
The sound depends on the impact and squeezing of the bearings. The trembling is caused by changes in the gap between the bearings and the deformation of the belt due to ageing. If the battery fault light comes on while driving, stop immediately and call for roadside assistance. There are only two possibilities. One is a generator failure, but generally speaking, generators are non-functional components.
It is not very likely that it will fail. The timing belt should then be checked for wear and tear or dislodgement. If the timing belt has fallen off, the car's generator will not work properly and the car will lose power and the battery fault light will appear. Generally speaking, it is best to have the timing belt checked and replaced every 30,000 to 40,000 kilometres, rather than waiting until there is a problem before replacing it.
Timing chains depend on mileage and usage. The average private car has a range of only 200,000 km and the current estimate is around 400,000 km. The chain will be stretched and deformed over time, resulting in deviations in the operation of the valve train, slightly inaccurate opening and closing of the intake and exhaust valves, poor acceleration and unstable engine operation.
If you have the patience, you can read your manual to understand the manufacturer's specifications. If you don't want to read a book, then wait five or six years after the car has been running and check the belt extension. It is easier to see that it is not old or damaged. If you see a crack, don't delay and replace it as soon as possible as it is a matter of life and death for the people in the car.
