Abstract

The invention discloses a multi-gear dynamic coupling drive system. The multi-gear dynamic coupling drive system comprises a one-way clutch, a first power source, a first planetary power transmissionsystem, a second planetary power transmission system and a second power source, a first sun wheel is connected with the first power source, a first planet wheel is rotatably connected with a first planet carrier, a second sun wheel is rotatably connected with a second planet wheel, the second sun wheel is connected with the second source, and a gear ring is separately connected with the first planet wheel and the second planet wheel to output power. The multi-gear dynamic coupling drive system can realize dynamic coupling of a coupled mode with multiple power sources and multiple power, so that the possibility of the multiple power sources in an efficient work area is achieved; the impact in the power switching process is reduced by using the first planetary power transmission system, thesecond planetary power transmission system and the one-way clutch, the difficulty of shifting control is simplified, the integration level is high, and the multi-gear dynamic coupling drive system isa pure electric drive scheme with multiple gears and high efficient.

Description

technical field [0001] The invention belongs to the technical field of power transmission components, and in particular relates to a multi-speed power coupling transmission system. Background technique [0002] With the society's increasing demand for energy-saving and environmental protection technologies, new energy vehicles represented by hybrid power transmission technology have become increasingly popular. At present, the speed-coupled ECVT power transmission scheme represented by Toyota Prius is more popular. Since there is no clutch in the Toyota ECVT system, the power coupling has only two power output modes: three power sources and one motor. deepening of degree. With PLUG-IN plug-in hybrid power becoming a future development direction, and the two motors in the Toyota ECVT, there is only one motor in the pure electric output, one power mode, and the other motor is only in the hybrid state In order to work, the performance of the motor and battery cannot be fully ...
