Most special purpose vehicles are manual transmission, and automatic concrete mixer is no exception. Manual transmission vehicles use more clutches. What factors limit the service life of clutches? The clutch is composed of moving plate assembly, clutch gland and cover assembly, release bearing and flywheel. The main materials are high strength steel, aluminum alloy, ball milled cast iron, etc. What we usually call the three piece clutch set refers to the clutch plate, pressure plate and release bearing. The service life of the clutch in general vehicles is about 60000 km.

自動(dòng)水泥自動(dòng)攪拌車(chē)的離合器壽命短受幾個(gè)方面的影響：

The short service life of the clutch of the automatic concrete mixer truck is affected by several aspects

1. 自動(dòng)水泥自動(dòng)攪拌車(chē)，長(zhǎng)時(shí)間踩住離合器，長(zhǎng)時(shí)間踩著離合器不放，那么離合器一直處于工作狀態(tài)，這樣長(zhǎng)時(shí)間的運(yùn)轉(zhuǎn)非常容易造成離合器過(guò)熱，磨損過(guò)度的。

1. For an automatic concrete mixer, if you step on the clutch for a long time, the clutch will always be in the working state. Such a long time operation is very easy to cause overheating and excessive wear of the clutch.

2. 長(zhǎng)時(shí)間半聯(lián)動(dòng)，這個(gè)指的是在車(chē)輛的行駛過(guò)程中，一直踩著離合，踩一半，放一半，這就屬于半聯(lián)動(dòng)，也叫半離合，這樣會(huì)導(dǎo)致分離軸承壽命嚴(yán)重縮短的，剎車(chē)片的壽命也會(huì)縮短的，也就縮短了離合器的壽命。

2. Semi linkage for a long time. This refers to that during the driving process of the vehicle, the clutch is always on, half on and half off. This belongs to semi linkage, also known as semi clutch. This will lead to a serious shortening of the service life of the release bearing, the service life of the brake pad, and the service life of the clutch.

3. 自動(dòng)水泥自動(dòng)攪拌車(chē)，起步油門(mén)過(guò)大，對(duì)于手動(dòng)擋，有些人在起步的時(shí)候，喜歡猛踩油門(mén)（離合器一端是連著發(fā)動(dòng)機(jī)，另一端是連著變速箱和車(chē)輪），油門(mén)過(guò)大，發(fā)動(dòng)機(jī)轉(zhuǎn)速一下就上來(lái)，離合器剛剛結(jié)合的時(shí)候兩端轉(zhuǎn)速相差就很大，一頭發(fā)動(dòng)機(jī)已經(jīng)轉(zhuǎn)的很快，那邊才慢慢接上去速度慢。這樣擰一下對(duì)離合器會(huì)產(chǎn)生額外的消耗，油門(mén)超大，要么離合器打滑，要么就是輪胎打滑，對(duì)車(chē)子都是不好的。長(zhǎng)時(shí)間這么開(kāi)車(chē)是會(huì)出問(wèn)題的，檔位高，速度低，從地面及變速箱傳來(lái)的阻力矩，就會(huì)特別的大。

three For automatic concrete mixer, the starting accelerator is too large. For manual transmission, some people like to step on the accelerator when starting (one end of the clutch is connected to the engine, and the other end is connected to the gearbox and wheels). If the accelerator is too large, the engine speed will come up immediately. When the clutch is just combined, the speed difference between the two ends is very large. One engine has turned very fast, and there is only one Slow down. Slow down. If you twist the clutch in this way, it will cause extra consumption. If the accelerator is too large, either the clutch slips or the tire slips, which is not good for the car. If you drive like this for a long time, there will be problems. If the gear is high and the speed is low, the resistance torque from the ground and the gearbox will be particularly large.

4. 自動(dòng)水泥自動(dòng)攪拌車(chē)，檔位越高，阻力矩就越大，阻力矩和變速箱的傳動(dòng)是成反比的，變速箱的檔位越高，傳動(dòng)比越小，阻力矩就越大，那連接發(fā)動(dòng)機(jī)變速箱的離合器，承受的負(fù)荷也就越大，就會(huì)加速離合器片的磨損。攪拌車(chē)的載重比較大，對(duì)于離合器的使用要謹(jǐn)慎小心，希望這些建議能給攪拌車(chē)司機(jī)帶來(lái)幫助！

4. For the automatic concrete mixer, the higher the gear, the greater the resistance torque. The resistance torque is inversely proportional to the transmission of the gearbox. The higher the gear of the gearbox, the smaller the transmission ratio, and the greater the resistance torque. The clutch connected to the engine gearbox will bear more load, which will accelerate the wear of the clutch plate. Mixer load is relatively large, for the use of clutch to be careful, I hope these suggestions can bring help to the mixer driver!
