本人学生,自己平时对混合动力比较感兴趣,因为专业原因,比较好奇混合动力在工程机械上的发展。这个图是Genie公司的高空作业车的一个专利。跟汽车的比较,我发现这个算不上传统意义上的并联结构,电动机(发电机)和发动机之间没有机电耦合(不是丰田THS那种行星轮式的。。)。关于回首能量,他们的注释中这样写道:The engine 140 is often operated at an approximately steady output to increase engine efficiency. When there is excess power output by the engine 140 that is not required to propel the vehicle100, the excess power may be transferred from the hydrostatic drive system through ground coupling to the electric drive system to back-drive the electric machines 134 as generators and charge the battery 160.
