Embodiment 1

[0025] Such as Figure 1 to Figure 3 As shown, a dual-motor series hybrid device in this embodiment includes a front transmission 2, a generator 4, a driving motor 5 and a rear transmission 6, the generator 4 and the driving motor 5 are integrated and located in the front transmission 2 and the rear derailleur, the rear derailleur 6 is located at the drive motor 5 side. In this embodiment, the engine 1 transmits power to the front transmission 2 through the input shaft 11. The front transmission 2 is a three-shaft two-speed transmission, which is a common transmission in the prior art and has a direct gear and an overdrive gear. Use overdrive gear when running at low speed, so that you can increase the speed of the generator, thereby improving power generation efficiency; use direct gear when the engine is running at high speed, so that you can avoid damage to the generator caused by overspeed running. In addition, the front derailleur can also form a combined transmission wi...

Embodiment 2

[0032] Such as figure 1 and as Figure 4 As shown, the difference between this embodiment and the above-mentioned embodiment is that the pure electric direct drive and pure oil two-gear structure of this embodiment, the driving motor 5 is a single-stage drive, and the pure oil drive or parallel hybrid of the rear transmission 6 has high-grade and low-gear two files. The driving gear 19C of the driving motor 5 is set on the motor shaft 18, the constant mesh output driving gear 27 of the rear derailleur 6, the low gear driven gear 29 of the rear derailleur 6, the driven gear 31C of the driving motor 5 and the intermediate shaft of the rear derailleur 6 28 is integrally arranged; the low-gear active gear 23 of the rear derailleur 6, the rear gear shift gear hub 25 of the rear derailleur 6 are set on the input shaft 18, and the rear gear shift gear sleeve 24 of the rear derailleur 6 is set on the shift gear hub 25 . The high and low gears of the rear derailleur 6 can be switche...

Embodiment 3

[0034] Such as figure 1 with Figure 5 As shown, the difference between this embodiment and the above-mentioned embodiments is that this embodiment has a pure electric two-gear and pure oil two-gear structure, the drive motor 5 has two high-gear and low-gear, pure oil drive and parallel hybrid rear transmission 6 There are two gears, high and low.

[0035] In this embodiment, the low gear active gear 19 of the driving motor and the high gear active gear 22 of the driving motor are arranged on both sides of the high and low gear gear hub 20 of the driving motor, and the high and low gear gear sleeve 21 of the driving motor is set on the high and low gear gear hub 20. On the gear hub 20; the rear gear shift gear sleeve 24 of the rear derailleur is sleeved on the rear gear shift gear hub 25, and the constant mesh output driven gear 26 of the rear derailleur and the low gear driving gear 23 of the rear derailleur are located on the rear gear shift gear On both sides of the hub 2...

Abstract

The invention relates to a dual-motor series-parallel hybrid power device and a vehicle. The dual-motor series-parallel hybrid power device comprises a front transmission 2, a generator 4, a driving motor 5 and a rear transmission 6, the generator 4 and the driving motor 5 are integrated together and located between the front transmission 2 and the rear transmission, and the rear transmission 6 islocated on one side of the driving motor 5. According to the dual-motor series-parallel hybrid power device and the vehicle, series hybrid power and parallel hybrid power can be achieved, the advantages of two different hybrid power modes can be fully utilized, the defects of the two different hybrid power modes are overcome, and the increasingly strict vehicle energy conservation and emission reduction requirements at present can be better met; besides, the manufacturing difficulty is low, the cost is low, application and popularization are facilitated, and great economic benefits and socialbenefits are achieved.

Description

technical field [0001] The invention relates to a vehicle hybrid power device, in particular to a dual-motor parallel hybrid power device and a vehicle. Background technique [0002] At present, the number of domestic automobiles is increasing continuously. With the full implementation of the national six emission standards for automobiles and the national three-stage automobile fuel consumption requirements, the requirements for automobile energy saving and emission reduction are becoming more and more stringent, and the traditional internal combustion engine technology has been highly mature. There is not much room for further energy saving, but the difficulty is great. Therefore, in order to further meet the requirements of energy saving and emission reduction, automobile hybrid technology has been highly valued. Among the existing hybrid technologies for automobiles, the automobile hybrid hybrid technology based on the electromechanical coupling structure of the wheel t...
