The invention discloses a driving system of a rear-drive hybrid vehicle, which belongs to the technical field of vehicle driving, and comprises: an engine, a connection and disconnection device for connecting the driving end to the engine through a first transmission shaft, and a connection disconnection device through a second transmission shaft. The first motor connected to the driven end of the opening device, one end is fixed on the second transmission shaft, the other end is fixed on the first gear assembly on the third transmission shaft, the second motor is fixed on the fourth transmission shaft, one end is fixed On the fourth transmission shaft, the other end is fixed to the second gear assembly on one end of the fifth transmission shaft; the rear differential device is respectively connected with the other end of the fifth transmission shaft and the rear drive shaft; engine, connection and disconnection device , the first motor and the second motor are arranged at intervals in sequence along the direction in which the front wheels of the vehicle point to the rear wheels. The engine in the invention can participate in driving when the vehicle speed is high, and not participate in driving when the vehicle speed is low, so that the vehicle can be in the most economical working mode and the fuel consumption of the vehicle is reduced.
Description
technical field [0001] The invention relates to the technical field of vehicle drive, in particular to a drive system of a rear-drive hybrid vehicle. Background technique [0002] A rear-drive hybrid vehicle refers to a vehicle that uses gasoline drive and electric drive to drive the rear wheels to rotate. Its advantage is that when the vehicle starts and stops, it is only driven by the motor, and the engine does not work. When reaching a certain speed, the engine rotates, so that the engine can always be kept in the best working condition, with good power and low emission. [0003] In the prior art, the transmission device of a hybrid vehicle usually adds an electric motor between the engine and the transmission on the basis of the gasoline drive device, so as to realize the function of electric drive. That is, by improving the ordinary automatic transmission into a hybrid transmission, hybrid drive can be realized. However, the transmission device formed in this way can...
