Double-shaft input hybrid power system and drive method

Abstract

The invention discloses a double-shaft input hybrid power system and a drive method. The double-shaft input hybrid power system comprises an engine, a second shaft, a shaft P3 and a third shaft. The second shaft, the shaft P3 and the third shaft are in transmission connection through a gearbox. A first shaft is connected to one side of the engine, a clutch is installed between the first shaft andthe engine, a transmission gear is installed on the first gear, a main speed reducer is installed at one end of the second shaft, a synchronizer is installed on one side of the main speed reducer, a first-gear gearshift gear is installed between the first shaft and the second shaft, an L-gear gearshift gear and an H-gear gearshift gear are installed between the third shaft and the shaft P3, a motor is installed on the shaft P3, and an axle shaft is connected between the shaft P3 and the second shaft and provided with a differential mechanism. A mode P2 and a mode P3 can be achieved through coupling of one motor, a large amount of cost can be saved, it can be guaranteed that an original vehicle still can travel normally after the motor breaks down, and the vehicle charges a battery in an idling state.

Description

technical field [0001] The invention relates to an automobile hybrid power system, in particular to a dual-shaft input hybrid power system and a driving method. Background technique [0002] As we all know, a hybrid vehicle refers to a vehicle that is equipped with two power sources at the same time. The thermal power source is generated by a traditional gasoline engine or diesel engine, and the electric power source is a battery and an electric motor. The actual operating conditions of the whole vehicle require flexible regulation, while the engine remains in the area with the best overall performance, thereby reducing fuel consumption and emissions. Hybrid vehicles use smaller engines that can meet the needs of vehicle cruising, relying on electric motors or other auxiliary devices Provides the additional power needed to accelerate and climb hills. The result is increased overall efficiency without sacrificing performance. Hybrids are designed to recover braking energy, wh...

Problems solved by technology

[0003] In the dual-shaft input hybrid power in the prior art, one motor cannot complete the switching between P2 mode and P3 mode, which increases cost resources. When the motor fails, the equipment cannot work normally, and power transmission cannot be performed through the engine. Idle charging cannot be performed, and the motor power cannot be guaranteed at all times, which limits the range of use of the equipment
