Embodiment 1

[0030] Such as figure 1 As shown, a vehicle drive assembly with longitudinal dual power sources provided by the present invention includes an automatic transmission 10, a first power source 71 and a second power source 72, wherein the transmission input shaft 21 and the transmission output shaft 32 of the automatic transmission 10 are coaxial line, the transmission input shaft 21 is connected to the output shaft of the first power source 71, the transmission output shaft 32 is connected to the input shaft of the second power source 72, and the output shaft of the second power source 72 is connected to the axle shaft, automatically The transmission 10 has two speed ratio transmissions.

[0031] The output shaft of the first power source 71 is coaxial with the transmission input shaft 21 and adopts an integrated structure. The input shaft of the second power source 72 is coaxial with the transmission output shaft 32 and adopts an integrated structure.

[0032] The automatic tra...

Embodiment 2

[0044] This embodiment is a change on the basis of the first embodiment, the difference is the structure of the shifting clutch. Such as figure 2 As shown, the third gear 13 in the second gear set is fixedly connected with the intermediate shaft 31, the fourth gear 14 is sleeved on the transmission output shaft 32, the second clutch 41 is arranged on the transmission output shaft 32, and is connected with the first clutch 42 The one-piece structure forms a two-way clutch 43 .

[0045] The two-way clutch 43 includes a double-end-tooth combination chainring, which can slide on the transmission output shaft 32 and can be matched by splines. The first gear 11 is provided with a right-side tooth, and the fourth gear 14 is provided with a left-side tooth. tooth, the fourth gear 14 is empty on the output shaft 32 of the automatic transmission. The double-end tooth combined chainring slides to the right and meshes with the left end tooth of the fourth gear 14. The power of the outp...

Embodiment 3

[0049] This embodiment is a variation on the basis of the second embodiment, the difference is the structure of the shifting clutch. Such as image 3 As shown, a first clutch 42 is provided in cooperation with the first gear 11 , and a second clutch 41 is provided in cooperation with the fourth gear 14 . The first clutch 42 includes a left end face toothed disc, and the second clutch 41 includes a right end face toothed disc. The left end face toothed disc and the right end face toothed disc can slide respectively on the transmission output shaft 32 and can be matched by splines. The first gear 11 is provided with right end face teeth, the fourth gear 14 is provided with left end face teeth, and the fourth gear 14 is idly sleeved on the output shaft 32 of the transmission. The second clutch 41 slides to the right and meshes with the teeth on the left end of the fourth gear 14, and the power of the output shaft of the first power source passes through the first gear 11, the se...

Abstract

The invention belongs to the technical field of new energy automobiles, and particularly relates to a longitudinal dual power source vehicle drive assembly which comprises an automatic transmission, afirst power source and a second power source, a transmission input shaft and a transmission output shaft of the automatic transmission share the same axial line, the transmission input shaft is connected with an output shaft of the first power source, the transmission output shaft is connected with an input shaft of the second power source, an output shaft of the second power source is connectedwith an axle half shaft, and the automatic transmission has two speed ratio transmission types. Direct drive and speed change functions and direct drive and speed reduction functions of dual motors can be achieved, various speed ratio transmission types are formed, transmission forms are flexible, the radial size of the drive assembly is reduced, power failure is omitted in gear shifting, and running smoothness, the power performance, the acceleration performance and the climbing capacity of a vehicle are improved.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a drive assembly of a vertical dual power source vehicle. Background technique [0002] In the current pure electric or hybrid new energy vehicles, the power characteristics of the electric motors used are different from the requirements of the whole vehicle, and cannot meet the requirements of speed ratio and torque. As new energy vehicles need to face more and more complex working conditions and road conditions, users have higher and higher requirements for the comfort and cruising range of new energy vehicles. Simple motor direct drive mode, motor connection reducer mode or gasoline-electric hybrid The model of new energy vehicles can no longer meet the development requirements of the new energy vehicle industry. [0003] The current automobiles are usually equipped with a single power source, and a transmission is connected to the single power source....
