Power system: The driving force 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 harsh working conditions and variable loads. 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, oil motor, etc. and convert it into mechanical energy. Principle control system of wheel loader: The control system is a system that controls the engine, hydraulic pump, multi-way reversing valve and executive components. 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.
