Embodiment approach

[0029] Further, according to an embodiment of the present invention, the hybrid drive system further includes a differential 11 , and the differential 11 is connected with the third gear 82 or the fourth gear 92 .

[0030] According to another embodiment of the present invention, a fifth gear (not shown in the figure) is fixed on the output shaft 16, and the differential 11 is connected with the fifth gear.

[0031] The differential is the main part that drives the car. The function of the differential is to transmit power to the half shafts on both sides while allowing the two half shafts to rotate at different speeds, so that the wheels on both sides can run at unequal distances in the form of pure rolling as much as possible. , to reduce the friction between the tire and the ground. Ordinary differentials are composed of planetary gears, planetary gear carriers (differential case), side gears and other parts. The power enters the differential, directly drives the planetary...

Abstract

A hybrid drive system, comprising an internal combustion engine, a first motor, a clutch and a second motor, wherein it also includes an output shaft for outputting power, a first input shaft and a second input shaft, the first input shaft and the output shaft The first transmission ratio is formed by one or more stages of gear pairs, the second transmission ratio is formed by one or more stages of gear pairs between the second input shaft and the output shaft, the internal combustion engine is connected with the first motor, and the first motor passes through the clutch It is connected with the first input shaft, and the second motor is connected with the second input shaft. The invention also provides a vehicle comprising the drive system. Since the present invention is provided with two input shafts and one output shaft, two gears of the forward gear of the vehicle are formed, and various working modes and corresponding gears can be flexibly selected according to different driving conditions of the vehicle, so it is very convenient It satisfies the driving needs of the vehicle under different working conditions.

Description

technical field [0001] The invention relates to a hybrid drive system and a vehicle including the drive system. Background technique [0002] In today's world, human beings are facing two major challenges: energy scarcity and environmental degradation. Traditional automobiles are increasingly plagued by the oil crisis. Energy conservation and environmental protection have gradually become the development theme of the automobile industry. In view of this, the call for the introduction of pure electric vehicles is increasing day by day. However, due to the constraints of many factors such as technology and policy, the current pure electric vehicles cannot be mass-produced and fully marketed. [0003] Due to its excellent performance in energy saving and environmental protection, hybrid electric vehicles are undoubtedly one of the most realistic technologies before the industrialization of pure electric vehicles. [0004] The prior art discloses a vehicle hybrid drive system, ...
