Abstract

The invention discloses a power driving system used for a pure electric vehicle and provided with a power separation device and a vehicle. The power driving system comprises a power driving system; the power driving system comprises a main driving system, an auxiliary driving system and a power driving control system; the main driving system comprises a main motor system and a main speed reducer;the main speed reducer comprises a main gear transmission system, a main differential mechanism and a main power separation device; the auxiliary driving system comprises an auxiliary motor system andan auxiliary speed reducer; the auxiliary speed reducer comprises an auxiliary gear transmission system, an auxiliary differential mechanism and an auxiliary power separation device; the power driving control system comprises a motor system control module and a power disengaging device control module; the power driving system has a four-wheel driving mode, a main driving system driving mode, an auxiliary driving system driving mode, an energy recovery mode and a brake mode; and the power driving control system outputs the driving signals of the power driving system based on control signals output by a vehicle control unit so as to realize the switching of the different modes. With the system adopted, the power performance and economical efficiency of the pure electric vehicle are improved.

Description

technical field [0001] The invention belongs to the technical field of pure electric vehicles, and in particular relates to a pure electric vehicle power drive system and a vehicle with a power separation device. Background technique [0002] As the global environment continues to deteriorate, green and environmentally friendly pure electric vehicles have gradually become the development trend of the automotive industry. As the core component of the power output of pure electric vehicles, the power drive system has an important impact on the performance of pure electric vehicles. [0003] At present, the power drive system of pure electric vehicles at home and abroad is mainly based on two-wheel drive. With the diversification of consumers' demand for power configuration of pure electric vehicles, four-wheel drive systems are gradually being applied to pure electric vehicles. Compared with traditional two-wheel-drive pure electric vehicles, four-wheel-drive pure electric ve...
