 Wheel loaders can be divided into: power system, mechanical system, hydraulic system, control system. As an organic whole, the wheel 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 motive power of the 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 wheel loader's working condition and variable load. Mechanical system: mainly includes walking gear, 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 power hydraulic energy 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. |
