The invention discloses a drive system of a hybrid vehicle, which belongs to the technical field of vehicle drive and includes an engine; a connection and disconnection device, one end of which is connected to the engine through a first transmission shaft; a first motor, which is connected to the disconnection device through a second transmission shaft The other end of the opening device is connected; the first gear assembly includes a plurality of gear pairs, the first motor is connected to one end of the second transmission shaft, and the third transmission shaft is rotatably connected to the second transmission shaft; the second motor is connected to the sleeve Connected to the fourth transmission shaft located on the outer periphery of the third transmission shaft; the differential device includes a front differential device and a rear differential device, and the rear differential device is respectively connected to the other end of the third transmission shaft and the rear drive shaft; the engine , the connection and disconnection device, the first motor and the second motor are arranged at intervals in sequence along the direction that the front wheels of the vehicle point to the rear wheels. The engine 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 reduce the fuel consumption of the vehicle.
Description
technical field [0001] The invention relates to the technical field of vehicle drive, in particular to a drive system of a hybrid vehicle. Background technique [0002] A hybrid vehicle refers to a vehicle that uses both gasoline and electric drive. 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 cannot control the engine to work in the low fuel consumption...
