摘要
通过分析,对混合动力汽车传动比的选择给出了初步结论:从动力性角度出发,当动力源工作在最大功率点时,恰当选择传动系统的总传动比,使得汽车能够达到最高设计车速,选择此时传动比为最小传动比;综合考虑最大爬坡度、附着率及汽车最低稳定车速3方面的问题确定最大传动比;最大和最小传动比之间的中间挡位应按照等比级数分配传动比的原则进行分配。
A primary conclusion is given for the selection of drive ratio of hybrid car based on analysis： from the dynamic point of view, when the power source operates at the maximum power point, selecting appropriately the overall drive ratio of the driveline, which enables the vehicle to obtain the maximum design speed, the drive ratio selected at this moment is the minimum drive ratio; define the maximum drive ratio based on the maximum gradient, adhesion rate and the minimum vehicle stable speed; the intermediate gear between the maximum and minimum drive ratio shall be assigned according to the principle of geometric sequence drive ratio assignment.
