Abstract

The invention provides a two-stage dual-motor hybrid automatic transmission, which includes an input shaft, an output shaft, two power motors, three planetary rows, two clutches and two brakes; the power motor has driving and power generation modes; the input The shaft is connected to the first planetary row frame through the first clutch, and at the same time, the first planetary row frame is connected to the transmission case through the first brake to achieve braking. The first planetary ring gear is connected to the second planetary row frame, and the second The clutch is connected to the third planetary row frame; both the first planetary row sun gear and the second planetary row ring gear are connected to the first power motor; the second planetary row sun gear is connected to the third planetary sun gear and connected to the second power motor The motor; the third planetary row frame is connected with the output shaft, and the third planetary row ring gear is connected with the casing through the second brake to realize braking. The invention can realize the energy saving when the engine stops during the operation of the transmission.

Description

technical field [0001] The invention relates to the technical field of machinery and vehicle transmission, in particular to a two-stage dual-motor hybrid automatic transmission. Background technique [0002] Hydromechanical automatic transmission for wheeled vehicles, including planetary row, clutch, housing, hydraulic control system. Transmissions can have multiple planetary rows, clutches, and internal rotating components. [0003] Different speed ratios of the transmission are realized by controlling different clutches, so as to meet the working speed ratio requirements of the transmission under different load conditions. Through the coordinated control of the internal combustion engine and the power motor, the continuous change of the output speed can be realized, and the economical efficiency of the vehicle can be improved. [0004] The existing automatic transmission does not have an engine stop function during operation, and part of the mechanical energy absorbed fr...
