摘 要
貨車作為一種常用的商務車，已在現(xiàn)代社會中占有舉足輕重的地位。由于貨車的快速發(fā)展，人們的生活才變得如此便利。貨車，成為了一個國家乃至整個世界不可缺少的一樣運輸工具。
變速器是汽車傳動系統(tǒng)結構中最重要的部分之一，汽車的前進、后退，增速、減速都要靠變速器傳動來實現(xiàn)。而且變速器在汽車動力性和燃油經(jīng)濟性上也有重要的影響。
本設計的CA5-38變速器，主要任務是完成齒輪、軸、箱體等的設計及校核，和位置的確定，并滿足其承載能力的同步器。另外，針對齒輪作用力的不同，可以在不同的軸上選擇合適的軸承。利用AUTCAD完成變速器的總成圖、第一軸、第二軸、中間軸、各個擋齒輪及同步器的設計。
隨著我國汽車行業(yè)的迅猛發(fā)展，人們對汽車的需求也越來越高。通過對載貨汽車變速器的設計我了解到變速器在汽車結構中具有著重要的作用。變速器結構的改進對汽車行業(yè)的發(fā)展與進步具有著深遠的意義。
關鍵詞：變速器；軸；齒輪；設計計算；校核
ABSTRACT
Nowadays, van as a kind of Business Purpose Vehicle has been common and played a very important role in our modern society. Because van develops so fast, people’s life become more and more convenience. Van, has been become an indispensable vehicle in a country, even all the world.
Transmission is the most important part in transmission agent in an auto. The reason is that forward, backward, speed up, slowdown and other manipulate of auto have to be completed by transmission. And transmission is also important in Automotive dynamica perform and fuel economy.
The main purpose of this design--CA5-38 gearbox is to complete the design, check and position among gears, axles, case, and this design should have enough capability. In addition, it can choose an appropriate bearing, which based on the different gears’ forces. We can complete this design, primary shaft, secondary shaft, intermediate shaft, any gear, and synchro by AUTCAD.
With the rapid development of Chinese automobile industry, people has more and more demands in autoes. To design this transmission of van; I realized that transmission is very important in van’s conformation. The developed of transmission is profound for growth and progress of autoes.
