摘要
变速器是完成传动系任务的重要部件,也是决定整车性能的主要部件之一。变速
器的设计水平对汽车的动力性、燃料经济性、换挡操纵的可靠性与轻便性、传动平稳
性与效率等都有直接的影响。随着汽车工业的发展,轿车变速器的设计趋势是增大其
传递功率与重量之比,并要求其具有更小的尺寸和良好的性能。本设计以车型 HGCU2
变速器为基础设计输入轴,在给定发动机输出转矩、转速及最高车速、最大爬坡度等
条件下,着重对变速器输入轴的结构参数进行设计计算以及对其进行工艺分析等。
我国的制造工艺与技术装备相对落后于工业发达的国家,我国大多数企业目前还
采用较落后的制造工艺及技术装备生产,优质高效率低耗工艺的普及率不足 10%数控
机床及高效设备不足 5%。在产品开发设计的技术手段方面,我国 CAD 的覆盖率仅为 5%。
不能及时开发设计具有创新和独占性的市场的新产品。总之,我
还存在阶段性的差距,而我国的机械制造装备产业也是大致如此。
当前,制造技术的发展趋势是:必须强化具有自己创新技术的产品开发能力,缩
短产品的上市时间,提高产品质量和生产效率,从而提高企业的市场应变能力和综合
竞争能力。重视先进的基本制造工艺与特种工艺的研究,重视使能技术的研究和先进
机床、刀具的研究,研究高性能的自动化加工机床,开发基于新工艺的装备等,乃是
当误之急。

ABSTRACT
Transmission is an important task plete ponents, Decision is one of
the ponents of vehicle performance. Transmission of the design level of the car
power, fuel economy, shifting control of the reliability and portability, stability and
efficiency of transmission has a direct impact. With the auto industry, car design trend is to
increase the transmission power and the weight of its transmission ratio, and request a
smaller size and good performance. The design with the model-based design HGCU2
transmission input shaft, at a given engine output torque, speed and maximum speed,
maximum degree climbing conditions, focusing on the transmission input shaft of the
structural parameters of the process design calculations and analysis of its And so on.
Manufacturing process in China is relatively backward equipment and technologies in
the industrial developed countries, the majority of our business is still a more backward
technology and equipment manufacturing technology and production process of
high-quality high-efficiency low ration rate of less than 10% C machine tools
and lack of efficient equipment 5%. In product development and design of technical tools,
CAD coverage of only 5%.Not timely development of innovative and exclusive design of
the market of new products. In short, the level of manu
