The Power Match System Design of ZL50 Loader
Abstract：Loader is a high efficiency, flexible, versatile engineering machinery, complex working condition, frequent load changes, changes in range. How to make the most simple and suitable for the engine and transmission with external loads have always maintained the most reasonable match loader transmission has long been a problem. In this thesis, ZL50 loader as an object, to solve its power plant power output characteristics and work, walking devices contradictions between the various power requirements, implementation and engine work together to ensure that the loader to use in different normal driving conditions and jobs , and has good power and economy. It has able to automatically adjust the output torque and speed; achieve from low to high speed light load heavy automatic transition; variable torque ratio, efficient wide area; starting, smooth shift engagement, stepless, reduce labor intensity of operators and improve comfort characteristics. And which components such as torque converter, clutch, steering pump, working pump design, determine their sizes. Clarify the main components of which works as well as the selection of design parameters and determine the principles and methods.
Keywords：ZL50 loader; Power match system; Hydraulic torque converter; The overrunning clutch
