ZL 50 Wheel loader
Loader definition
Construction of water and electricity, ports, mining and other engineering conditions of construction machinery, it is mainly used to shovel, sandstone, lime soil, coal and other material, can also be used for ore, hard soil, such as mild shovel dug homework. Change of different auxiliary work unit can also be bulldozing, lifting and other materials such as wood handling operation. During the construction of roads, especially in the high grade highway, the loader used in subgrade engineering fill dig, asphalt mixture of aggregate and cement concrete yard and loading operations. It also can be a force behind the soil, ground leveling and other machinery operation traction. Because the loader has operation speed, high efficiency, good maneuverability, the advantages of convenient operation, so it has become one of the main models of the conditions in the construction of engineering construction.
Main components of
Including engine, torque converter, gearbox, drive axle, before and after referred to as "four items
1. The engine
2. On the torque converter has three pumps, pump work (supply lifting, skip pressure oil) steering pump to pressure oil (supply) variable speed pumps also called walking (for strain, torque transmission pressure oil), some models on the steering pump is equipped with pilot pump control valve pilot pressure oil (supply)
3...Working hydraulic oil, hydraulic oil tank, pump, multi-way valve, lifting oil cylinder and skip the oil cylinder
4. The walking hydraulic system: Transmission oil sump oil, pump, walking all the way into the torque converter valve all the way into gear, transmission clutch
5. Driver: The shaft, the main differential, wheel reducer
6. Turned to oil, fuel tank, steering pump, steady flow valve (or valve) steering, steering cylinder
7. The gearbox is one of the (planetary) and fission (shaft) two kinds
