What is the function of the gearbox and clutch attached to the heavy truck on the heavy truck?
Heavy truck transmission and clutch are started, because the transmission load is much larger than the family car, so the parts are bulky and manpower can not be pushed, so it is driven by air pressure, and also has hydraulic pressure. The pressure is relatively simple.
The truck's pressure plate and so on, heavy heavy, only by the oil pressure is not good, need to be in the high-pressure gas to promote separation, [oil top switch off - ventilation - high pressure gas push rod separation]The transmission principle of the trachea, similar to the above, in the manual, in promoting under the high pressure gas block,The other is to change the high and low gas path
The air pipe on the transmission is designed to make the transmission of the heavy truck easier, and because the heavy truck cab is farther away from the gearbox, the joystick is too far away and has an impact on the accuracy of the operation. It is better to install a trachea at the gearbox lid instead of the remote lever.
Heavy truck for easy handling, many take the form of pneumatic booster, such as pneumatic clutch, because the traditional hydraulic pump can provide the force is too small, the clutch and clutch slave cylinder does not allow you to do much;
