摘要
采用杠杆法将三行星排行星变速器的基本构成表示为3种杠杆形式,使行星变速器的设计变得直观。以4节点杠杆形式(1+2方案)为例,提出了变速器的输入、输出和制动的各种布置形式,全面而具体地说明了三行星排行星变速器传动方案的设计方法。给出了在换挡过程中只接合一个结合元件、分离一个结合元件换挡的三行星排行星变速器传动简图,该行星变速器能实现8个前进挡(5个减速挡,1个直接挡,2个超速挡)和2个倒挡。
With lever analogy, the basic structure of three-row planetary transmission can be expressed to three kind levers,which makes the design more intuitive. Various layout forms of input, output and braking elements are proposed under the example of the four-node lever form（1＋2 scheme）, and the design method of transmission scheme for three-row planetary transmission is fully described. As a result, the transmission diagram for three-row planetary transmission is designed, which just needs to engage or release one clutch during shifting process. This scheme can achieve 8 forward ratios（5 underdrive ratios, 1 direct ratio, 2 overdrive ratios） and 2 reverse ratios.
