Abstract

The invention provides an optimized integrated system with a drive motor and an automatic transmission and a gear shifting control method. The optimized integrated system comprises the drive motor, an input shaft, a torsional damper, the automatic transmission, a transmission shaft, a main speed reducer and an integrated control unit. An output shaft of the drive motor is connected with one end of the torsional damper through a spline, and the other end of the torsional damper is connected with an input shaft of the automatic transmission through a spline. An output shaft of the automatic transmission is connected with one end of the transmission shaft through a universal joint, and the other end of the transmission shaft is connected with the main speed reducer through a universal joint. The drive motor is directly connected with the automatic transmission through the torsional damper, damage of impact generated in the gear shifting process to the shaft of the drive motor is reduced, and meanwhile, the gear shifting failure rate caused by gear shifting impact is reduced. According to the optimized integrated system, the gear shifting time is shortened, the phenomena of power impact and unsmooth gear shifting are eliminated, equipment abrasion is lowered, and the dynamic performance, the economic performance and the smoothness of an electric automobile are improved.

Description

Technical field [0001] The invention belongs to the field of automobile power transmission research, and specifically relates to an optimized integrated system of a drive motor and an automatic transmission and a shift control method. Background technique [0002] At present, the domestic electric vehicle transmission system mostly adopts the direct drive mode of the drive motor, and many pure electric buses on the market adopt the direct drive motor with high power and torque. Although the use of this drive mode reduces the difficulty of matching the design of the power system, it greatly increases the investment in the drive motor. The drive motor used in this situation has large volume, heavy weight, low utilization efficiency, and drive controller Various drawbacks such as low effective capacity utilization and waste of energy have seriously affected the promotion and application of electric vehicles. Furthermore, the analysis and application of the existing electric vehicle...
