The function of the clutch friction plate of concrete mixer is to transfer the engine power to the transmission gear, and then output it to the rear wheel to drive the truck. The clutch plate can be separated and combined to cut off and combine the power transmission. The clutch and clutch plate can make the power softer and play a certain buffer role between the engine and the wheel to make the vehicle run Smooth start, smooth shift and prevent overload damage to the engine and transmission system. The importance of the mixer clutch is needless to say in detail, and the accident caused by the failure of the mixer clutch is often alarming. So since the mixer clutch is so important, what is the service life of the concrete mixer clutch? What factors restrict it? Or what kind of condition needs to be replaced? Next, the technicians will solve the problem in detail.
Factors affecting short service life of concrete mixer clutch
1. If the mixer holds the clutch for a long time and does not release the clutch for a long time, then the clutch is always in the working state. Such a long time of operation is very easy to cause overheating and excessive wear of the clutch.
2. The long-time semi linkage of mixer truck refers to that during the driving process of the vehicle, the clutch is always stepped on, half stepped and half released. This belongs to semi linkage, also known as semi clutch. This will lead to serious shortening of the service life of the release bearing and the service life of the brake pad, which also shortens the service life of the clutch.
3. The accelerator of the concrete mixer is too large. For manual transmission, some people like to step on the accelerator (one end of the clutch is connected to the engine, and the other end is connected to the gearbox and the wheel). 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 will be very large. The engine at one end has been rotating very fast, and the other side is slowly It's slow to connect. This will cause extra consumption on the clutch. If the accelerator is too large, either the clutch slips or the tires slip, which is not good for the car. If you drive like this for a long time, there will be problems. The gear is high and the speed is low. The resistance torque from the ground and the gearbox will be very large.
4. The higher the gear of the mixer truck is, the greater the resistance torque is. The resistance torque is inversely proportional to the transmission of the gearbox. The higher the gear of the gearbox is, the smaller the transmission ratio is, the greater the resistance torque is. The greater the load of the clutch connected to the engine gearbox will be, and the wear of the clutch plate will be accelerated.
Concrete mixer truck load is relatively large, for the use of clutch to be careful, I hope I said a few points to help the truck driver!
