摘 要 Abstract Stepless speed technology USES belt and the work of the Lord diameters driven pulley, cooperated with the power to deliver, can realize the TRANSMISSION ratio of the continuous change, and get the TRANSMISSION and engine condition the best match between. Common step-less transmission have hydraulic mechanical step-less transmission and belt type step-less transmission , the current domestic market of the vehicles already more and more. Editor this section step-less transmission and the origin of the automatic transmission. Automatic transmission is easy to operate, reduce fatigue driving, born of the gear drive system, the control method, it can be divided into the hydraulic controlled hydraulic and electric automatic transmission hydraulic automatic transmission; According to the change of the transmission way and can be divided into have levels of automatic transmission and no levels of automatic transmission. Therefore, step-less transmission is actually a kind of automatic transmission, but it than common automatic transmission is much more complex, more advanced technologies. Step-less transmission and common hydraulic automatic transmission of the biggest differences is on the structure, the latter is by hydraulic control gear drive system structure, still have the gears, it can be realized in between the two block is continuously variable transmission , and is two groups plate and a belt speed of than traditional automatic transmission, simple structure, smaller. In addition, it is free to change gear ratios, so as to realize the full speed stepless speed change, make more smoothly, without the traditional transmission shift at the feeling. Editor this section step-less transmission classification. Key words:Stepless speed technology；Automatic transmission；reduce fatigue driving 目 录 摘 要 III Abstract IV 目 录 V 1 绪论 1 1.1 无极变速器的发展 1 1.1.1 国外无极变速器的发展及现状 1 1.1.2 国内无级变速器的发展及现状 2 2 纸长调节无极变速器的结构及传动原理 4 2.1 纸长调节无极变速器的结构 4 4 2.2 传动原理 4
