Main structure of XCMG wheel loader

Loaders are generally composed of frame, power transmission system, walking device, working device, steering brake device, hydraulic system and control system. The power of the engine 1 is transmitted to the gearbox 14 via the torque converter 2, and the gearbox transmits the power to the front and rear axles 10 via the drive shafts 13 and 16, respectively, to drive the wheels to rotate. The internal combustion engine power also drives the hydraulic pump 3 to work through the transfer case. The working device consists of a boom 6, a rocker 7, a connecting rod 8, a bucket 9, a boom hydraulic cylinder 12 and a rocker hydraulic cylinder 5. One end of the boom is hinged on the frame, and a bucket is installed at the other end. The lifting of the boom is driven by the boom hydraulic cylinder, and the turning of the bucket is realized by the bucket hydraulic cylinder through the rocker arm and the connecting rod. The frame 11 is composed of front and rear parts, and the hinge pin 4 is connected in the middle, and the front and rear frame can be relatively rotated around the hinge pin by means of the steering hydraulic cylinder to realize steering.

Loaders can be divided into: power system, mechanical system, hydraulic system, and control system.
