Background technique

The power system in the mining dump truck is the heart of the construction machinery, which is responsible for the entire power output of the entire construction machinery. The difference between mining dump trucks and other non-construction machinery is that the working environment is very harsh, which forces the anti-vibration effect of the power system of mining dump trucks to be more prominent than that of non-construction machinery. The anti-vibration of the power system is generally achieved by arranging the mount, which is mainly reflected in the mount of the engine. The power system of the existing mining dump truck is mainly in the form of the engine directly driving the gearbox, and the mounting form it adopts is mainly four-point mounting or three-point mounting, and the four-point mounting method has no compliance effect. It is ideal. When the frame is deformed, some mounting points will be dislocated, causing the engine or the mounting bracket to be overstressed and causing damage. Although the three-point mounting has a good compliance effect, the stability and force balance are not good.
