Abstract:
Loader is a high operating efficiency and flexibility, uses a wide range of engineering machinery, complex and ever-changing operating conditions, load changes frequently, changes in range. How the most simple and appropriate to make the engine and drive system with the external load is always maintained between the most reasonable match, has been a long time loader transmission problem. In this paper, ZL50 loader for the object to its line of hydraulic drive system design, the hydraulic system and the parameters of the calculation of a reasonable choice.
Because we use hydraulic transmission, the system not only has good performance and flexibility of stepless speed regulation characteristics of the layout, but can a wide range of adjustment and control. In particular the use of a proportional control valve to make it compatible with computer control technology, can be achieved, such as construction machinery loader intelligent, energy-saving and environmental protection.
