As a Wheel Loader China Factory, there is some information about wheel loader sharing for everyone. Wheel loader is a kind of shoveling transport machinery widely used in highways, railways, ports, terminals, coal, mining, water conservancy, national defense and other projects and urban construction. It plays an important role in reducing labor intensity, speeding up project construction and improving project quality.
Chinese Wheel Loader
The main function of Chinese Wheel Loader is to carry out shovel loading and short-distance transportation of loose materials. It is one of the fastest-growing models in construction machinery, with the largest production and sales volume and market demand. What we usually see most is the wheel loader, which is the crawler loader. Compared with the crawler type, it has the advantages of good maneuverability, no damage to the road surface, and convenient operation. Therefore, wheel loaders are widely used.
The basic structure loader is generally composed of a frame, a power transmission system, a traveling device, a work device, a steering brake device, a hydraulic system, and a steering system. The power of the engine is transmitted to the gearbox via the torque converter, and the transmission is transmitted to the front and rear axles via the transmission shaft and respectively to drive the wheels to rotate. The internal combustion engine power is also driven by a transfer case driven the hydraulic pump. The working device is composed of a boom, a rocker arm, a connecting rod bucket, a boom hydraulic cylinder and a rocker arm hydraulic cylinder. One end of the boom is hinged on the frame, and the other end is equipped with a bucket. The lifting of the boom is driven by the boom hydraulic cylinder. The turning of the bucket is realized by the bucket hydraulic cylinder through the rocker arm and the connecting rod. The frame consists of two parts, the front and the rear, and the middle part is connected by a hinge pin. The steering hydraulic cylinder can make the front and rear frames rotate relative to the hinge pin to realize the steering.
As can be seen from the overall structure of the loader, the loader can be divided into power systems, mechanical systems, hydraulic systems, control systems. As an organic whole, the loader's performance is not only related to the performance of the mechanical components of the working device, but also related to the performance of the hydraulic system and control system. Power system: The original power of the loader is generally provided by the diesel engine. The diesel engine has the characteristics of reliable operation, hard power characteristic curve and fuel economy, which meets the requirements of the loader's working condition and variable load.
Mechanical system: mainly includes walking device, steering mechanism and working device. Hydraulic system: The function of the system is to convert the mechanical energy of the engine into fuel medium, use the oil pump to convert into hydraulic energy, and then transfer it to the cylinder, oil motor, etc. to convert into mechanical energy. Control System: The control system is a system that controls the engine, hydraulic pump, multi-way valve and actuator. The hydraulic control drive mechanism is a device that converts micro-power electrical energy or mechanical energy into powerful hydraulic and mechanical energy in a hydraulic control system. It consists of hydraulic power amplifying components, hydraulic actuators and loads and is the core of static and dynamic analysis in hydraulic systems.
