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.

自动水泥自动搅拌车的离合器寿命短受几个方面的影响：

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

1. 自动水泥自动搅拌车，长时间踩住离合器，长时间踩着离合器不放，那么离合器一直处于工作状态，这样长时间的运转非常容易造成离合器过热，磨损过度的。

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. 长时间半联动，这个指的是在车辆的行驶过程中，一直踩着离合，踩一半，放一半，这就属于半联动，也叫半离合，这样会导致分离轴承寿命严重缩短的，刹车片的寿命也会缩短的，也就缩短了离合器的寿命。

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. 自动水泥自动搅拌车，起步油门过大，对于手动挡，有些人在起步的时候，喜欢猛踩油门（离合器一端是连着发动机，另一端是连着变速箱和车轮），油门过大，发动机转速一下就上来，离合器刚刚结合的时候两端转速相差就很大，一头发动机已经转的很快，那边才慢慢接上去速度慢。这样拧一下对离合器会产生额外的消耗，油门超大，要么离合器打滑，要么就是轮胎打滑，对车子都是不好的。长时间这么开车是会出问题的，档位高，速度低，从地面及变速箱传来的阻力矩，就会特别的大。

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. 自动水泥自动搅拌车，档位越高，阻力矩就越大，阻力矩和变速箱的传动是成反比的，变速箱的档位越高，传动比越小，阻力矩就越大，那连接发动机变速箱的离合器，承受的负荷也就越大，就会加速离合器片的磨损。搅拌车的载重比较大，对于离合器的使用要谨慎小心，希望这些建议能给搅拌车司机带来帮助！

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!
