The gearbox is one of the important parts of the mixer truck, and correct operation of the gearbox can save fuel consumption. The manufacturer of the mixer truck will show you some precautions.
The mixer truck is a single H operated gearbox:
This gear has only one neutral gear, and all gears corresponding to low gear and high gear are coincident, including neutral gear.
Therefore, its high and low gear conversion can not be achieved by the horizontal racket, but by pulling the high and low gear toggle button on the side of the cab gear change handball downward and upward to achieve the high and low gear conversion.
The downward direction is for resistance, and the upward direction is for high gear. The single H valve is actually a single way air valve. The air flow pushes the shift fork to shift gears. The single H valve is used to switch the basic gear without auxiliary gear.
Double H operated gearbox of mixer truck:
Double H is a two-way air valve, one of which realizes the 220.127.116.11 shift through the sub box, and the other realizes the 18.104.22.168 shift at high speed through the sub box.
The double H valve is mainly used to realize the high and low gear shift and basic gear shift with the auxiliary box. The main box and the auxiliary box are separated. The shift action of the main box and the shift action of the auxiliary box need to be done at the same time, and the combination is to engage the high gear, so it needs to be realized by the double way air valve.
The correct operation of the transmission can also extend its service life. Therefore, when you drive the mixer, you must fully understand its gearbox, and pay more attention to our website http://www.jfhntjbj.com Come on!
