论文题目
汽车三轴五档变速器的设计
一课题研究的背景
汽车行驶的速度是不断变化的,这就要求汽车的变速器的变速比要尽量多,这就是无级变速(Continuously VariableTransmission简称"CVT")。尽管传统的齿轮变速箱并不理想,但其以结构简单、效率高、功率大三大显著优点依然占领着汽车变速箱的主流地位。在跨越了三个世纪的一百多年后的今天,汽车还没有使用上满意的无级变速箱。这是汽车的无奈和缺憾。但是,人们始终没有放弃寻找实现理想汽车变速器的努力,各大汽车厂商对无级变速器(CVT)表现了极大的热情,极度重视CVT在汽车领域的实用化进程。这是世界范围尚未根本解决的难题,也是汽车变速器的研究的终极目标。
二课题研究的要求
1 保证汽车有必要的动力性和经济性。
2 设置空挡,用来切断发动机动力向驱动轮的传输。
3 设置倒档,使汽车能倒退行驶。
4 设置动力输出装置,需要时能进行功率输出。
5 换挡迅速,省力,方便。
6工作可靠。汽车行驶过程中,变速器不得有跳
