Embodiment 1

[0050] A typical embodiment of the present invention is composed of engine 1, generator 2, clutch 3, motor 4, speed changer 5, differential 6, drive wheel 7, and the energy storage controller 8 is connected with generator 2 and motor 4 respectively. , accumulator 9, refer to figure 1 shown.

[0051] When the vehicle starts, the clutch 3 is in a disengaged state, and the motor 4 drives the input shaft of the transmission 5, which is transmitted to the output shaft through the relevant gear position of the transmission 5, and drives the vehicle to start running. When the energy output of the storage battery 9 drops to the lower limit of its design capacity, the engine 1 is started and the clutch 3 is engaged. At this time, the output power of the engine 1 is determined by the position of the working stroke of the accelerator pedal, which is in one of the two (or more than two) pre-selected working conditions. Due to the existence of the generator in the energy storage load, re...

Embodiment 2

[0055] In this embodiment, since the energy storage load is essentially an electric or hydraulic transmission system, the transmission in the vehicle is replaced with an epicyclic differential gear train, and various stepless adjustments desired when the vehicle is running can be obtained. The speed ratio of the transmission can reduce the volume and weight of the gearbox, and reduce the cost of vehicle manufacturing and maintenance.

[0056] like figure 2 As shown, the flow diagram of the power transmission of the second embodiment of the present invention is sequentially connected by the engine 1, the generator 2, the clutch 3, the epicyclic differential gear train 10, the differential 6, and the drive wheel 7, and the energy storage controller 8 A generator 2 , an electric motor 4 , and a storage battery 9 are connected, and the electric motor 4 is connected to an epicyclic differential gear train 10 .

Embodiment 3

[0058] In this embodiment, the generator and the motor are replaced by a combined generator and motor. like image 3 As shown, it is a schematic flow chart of power transmission in this embodiment. The engine 1, clutch 3, generator-motor 11, transmission 5, differential 6, and drive wheels 7 are sequentially connected, and the energy storage controller 8 is connected to the generator-motor. 11. Battery 9.

[0059] During the working process of this embodiment, the engine remains in an idling operating condition to meet the shifting requirements of the transmission. When the vehicle is stationary, if the transmission is placed in a neutral position, all the output power of the engine is used for the generator, and the converted energy is delivered to the storage battery for storage.
