The operation system of wheel loader

Loaders can be divided into: power system, mechanical system, hydraulic system, and control system. As an organic whole, the performance of the loader is not only related to the performance of the mechanical parts of the working device, but also related to the performance of the hydraulic system and the control system.

Power system: The driving force of the loader is generally provided by the diesel engine, which has the characteristics of reliable operation, hard power characteristic curve, and fuel economy, which meets the requirements of the loader's harsh working conditions and variable load.

Mechanical system: mainly includes walking device, steering mechanism and working device.

Hydraulic system: The function of this system is to use fuel as the medium of the mechanical energy of the engine, convert it into hydraulic energy by the oil pump, and then transfer it to the oil cylinder, motor, etc. and convert it into mechanical energy.

Control system: The control system is a system that controls the engine, hydraulic pump, multi-way reversing valve and actuators. The hydraulic control drive mechanism is a device that converts small power electrical or mechanical energy into powerful hydraulic and mechanical energy in a hydraulic control system. It is composed of hydraulic power amplifier components, hydraulic actuators and loads. It is the core of static and dynamic analysis in the hydraulic system.
