5吨装载机动力匹配系统设计+CAD图纸
（1）能够自动调节输出扭矩和转速；
（2）实现由低速重载到高速轻载的自动过渡；
（3）变矩比大，高效区域宽；
（4）起动、换挡接合平稳，实现无级变速，减轻操作人员劳动强度，提高舒适性。
主要任务有：
（1）柴油机输出的动力具有转矩小、转速高和转矩、转速变化范围小等特点，这与装载机作业或行驶时所需要的大转矩、低转速以及转矩、转速变化范围大之间存在着矛盾。为此，采用传动系统将柴油机的动力根据需要适当降低转速、增大转矩使之满足装载机作业或行驶的需要；
（2）综合运用过去所学理论知识，提高理论联系实际和综合分析能力，培养机械、液压综合设计能力；
（3）提高查阅设计资料、标准及规范等基本技能和设计能力，并完成毕业设计论文、计算说明书等。

5 tons loaders power match system design
abstract ZL50 loader power match system design to solve power plant power output characteristics, and the contradictions between work, walking device power demand, the implementation and engine work together, to ensure the use of loader in different under the condition of normal driving and assignments, and has good power performance and fuel economy. To have the following features:
(1) to automatically adjust the output torque and rotational speed;
(2) to realize the automatic transition to the high speed light load of low speed and heavy loading.
(3) torque than the big, efficient wide area;
(4) the starting and shifting smooth joint, realize stepless speed, reduce the operator labor intensity, improve the comfortableness.
Main tasks are:
(1) the output power of diesel engine with a small torque, high rotation speed and torque, low speed range, etc, with the loader at job or need high torque, low speed and large range of torque and rotational speed changes between the contradictions. To this end, the transmission system will be the power of diesel engine according to the need to decrease the speed and increase torque to meet the needs of the loader operation or driving;
(2) the integrated use of past learned theory knowledge, improve the theory with practice and comprehensive analysis ability, train the ability of mechanical and hydraulic integrated design;
(3) to improve access to design data, standards and specifications and other basic skills and design capability, and complete the graduation design paper, computing instruction, etc.
Key words: loader; Power performance. Diesel engine; Torque...
