[0039] figure 1 It is a structural schematic diagram of the hybrid drive system according to the first embodiment of the present invention. Such as figure 1 As shown, the hybrid drive system 10 includes an engine 11 , a planetary gear device 12 , a first motor 13 , a switch device, an intermediate shaft 17 , a second motor 18 , a differential 19 and a power battery (not shown).

[0040] The engine 11 has an engine output shaft 112 . In this embodiment, the engine 11 is, for example, a gasoline engine or a diesel engine.

[0041] The planetary gear device 12 includes a first rotation element, a second rotation element, and a third rotation element. The first rotary element is connected to the first motor 13 , and the second rotary element is connected to the engine 11 . In this embodiment, the first rotating element 122 is, for example, the sun gear 122 , the second rotating element is, for example, the planet carrier 124 , and the third rotating element is, for example, th...

[0064] Figure 11 It is a structural schematic diagram of the hybrid drive system according to the second embodiment of the present invention. Such as Figure 11 As shown, the hybrid drive system 10 of the present embodiment has substantially the same structure as the hybrid drive system 10 of the first implementation force, except that the installation positions of the first clutch 14 and the second clutch 16 are different.

[0065] Specifically, the first clutch 14 and the second clutch 16 are arranged in the same housing, and the first clutch 14 and the second clutch 16 are arranged coaxially. Since the first clutch 14 and the second clutch 16 are integrated in one housing, the volume occupied by the first clutch 14 and the second clutch 16 can be greatly reduced, and space is reserved for the arrangement of other components of the engine.

[0067] The hybrid drive system 10 of the present embodiment has substantially the same structure as the hybrid drive system 10 of the first embodiment, except that the connection relationship between the engine 11 and the planetary gear device 12 and the connection relationship between the clutch gear device and the planetary gear device 12 are different. .

[0068] Specifically, in this embodiment, the first rotating element is a sun gear, the second rotating element is a ring gear, the third rotating element is a planetary carrier, and the switching device is a brake or a one-way clutch, that is to say, the ring gear 123 and The engine output shaft 112 is connected, and the second clutch 16 is fixed on the planet carrier 124 . Please refer to the first embodiment for the connection relationship and driving method of the components of the hybrid drive system 10 .

[0069] The hybrid drive system 10 of this embodiment has a first-level pure electric mode, a second-level pure ...

The hybrid power drive system is good in platformization.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a hybrid drive system. Background technique [0002] At present, there are two main types of transmissions on the market: stepped transmissions and continuously variable transmissions. Stepped transmissions are subdivided into manual and automatic. Most of them provide a limited number of discrete output and input speed ratios through different meshing arrangements of gear trains or planetary gear trains. The adjustment of the driving wheel speed between two adjacent speed ratios is realized by the speed change of the internal combustion engine. CVT, whether it is mechanical, hydraulic, or electromechanical, can provide an infinite number of continuously selectable speed ratios within a certain speed range. In theory, the speed change of the driving wheel can be completely completed through the transmission. . In this way, the internal combustion engine can work in the opt...
