| Abstract: | In order to improve the structure and performance,a fourth gear automatic transmission which has a CR-CR double planetary gear mechanism is taken as the example.And a characteristic equation,which shows the general law of motion of the single-row planetary gear mechanism,is used to analysis the motion law of the automatic transmission."meshing power method" is also used to calculate the efficiency of the automatic transmission.Meshing power method is an approach that first translates planetary gear mechanism into fixed axis gear trains,then solves the transmission efficiency problem. |
