摘要ZL50裝載機動力匹配系統設計要解決動力裝置功率輸出特性和工作、行走裝置動力需求之間的各種矛盾,實現與發動機協同工作,以保證裝載機在不同的使用條件下正常行駛和作業,并具有良好的動力性和經濟性。要具有以下特點:35323
 (1)能夠自動調節輸出扭矩和轉速;
 (2)實現由低速重載到高速輕載的自動過渡;
 (3)變矩比大,高效區域寬;
 (4)起動、換擋接合平穩,實現無級變速,減輕操作人員勞動強度,提高舒適性。
  主要任務有:
(1)柴油機輸出的動力具有轉矩小、轉速高和轉矩、轉速變化范圍小等特點,這與裝載機作業或行駛時所需要的大轉矩、低轉速以及轉矩、轉速變化范圍大之間存在著矛盾。為此,采用傳動系統將柴油機的動力根據需要適當降低轉速、增大轉矩使之滿足裝載機作業或行駛的需要;
 (2)綜合運用過去所學理論知識,提高理論聯系實際和綜合分析能力,培養機械、液壓綜合設計能力;
 (3)提高查閱設計資料、標準及規范等基本技能和設計能力,并完成畢業設計論文、計算說明書等。

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...
