Embodiment 1

[0050] Embodiment 1 of the present invention provides a vehicle drive assembly with horizontal dual power sources, which is connected to the axle shaft, such as figure 1 As shown, the vehicle drive assembly includes a first power source, a second power source and an automatic transmission. The automatic transmission is provided with a first input shaft 21 and a second input shaft 22. The power source is connected to the two input shafts respectively. The first The power source is connected to the first input shaft 21, and the second power source is connected to the second input shaft 22; a differential is arranged at the joint between the automatic transmission and the axle shaft;

[0051] In the automatic transmission, a first intermediate shaft 31 is arranged coaxially with the first input shaft 21, and a second intermediate shaft 32 is arranged coaxially with the first intermediate shaft 31;

[0052] A second input shaft 22 is arranged in the direction coaxial with the seco...

Embodiment 2

[0078] Embodiment 2 of the present invention is an improvement made on the basis of Embodiment 1. The difference between Embodiment 2 of the present invention and Embodiment 1 is that, as figure 2 As shown, the fourth intermediate shaft 34 is also provided with a sixth gear 16; the sixth gear 16 is engaged with the third gear 13 on the second intermediate shaft 32; the fourth gear 14 is only engaged with the fifth gear 15 for transmission.

[0079] Setting the third gear 13 and the sixth gear 16 mesh transmission ratio is i5;

[0080] When the first clutch 41 is engaged and the second clutch 42 is disconnected, the gear ratio of the automatic transmission is i1×i3; the first power source sequentially passes through the first input shaft 21, the first intermediate shaft 31, the first gear 11, the second The gear 12 , the third countershaft 33 , the first clutch 41 , the fourth countershaft 34 , the fourth gear 14 , the fifth gear 15 and the differential 50 transmit power to th...

Embodiment 3

[0086] Embodiment 3 of the present invention is a change made on the basis of Embodiment 2. The difference between Embodiment 3 and Embodiment 2 is that, as image 3 As shown, the second input shaft 22 and the second intermediate shaft 32 are two independent shafts, and a third clutch 43 is provided between the second input shaft 22 and the second intermediate shaft 32 .

[0087] When the second power source motor 60 is used as an auxiliary power source, when starting the second power source motor 60, the third clutch 43 needs to be combined; when the second power source motor 60 is closed, the third clutch 43 can be disconnected, and now the motor 60 will Without idling with the running of the whole vehicle, the driving of the whole vehicle will not be restricted by the maximum rotating speed of the electric motor 60 and the moment of inertia of the rotor.

[0088] Other contents of Embodiment 3 of the present invention are the same as Embodiment 2, and will not be described ...

Abstract

The invention discloses a transversely-arranged double-power-source vehicle driving assembly. The transversely-arranged double-power-source vehicle driving assembly comprises a first power source, a second power source and an automatic transmission. The automatic transmission is provided with a first input shaft and a second input shaft. The power sources are connected with the two input shafts correspondingly. A first intermediate shaft, a second intermediate shaft and the second input shaft are arranged in the direction coaxial with the first input shaft. A third intermediate shaft is parallelly arranged with the first input shaft. A fourth intermediate shaft is arranged in the direction coaxial with the third intermediate shaft. A first gear on the first intermediate shaft is in engagement transmission with a second gear on the third intermediate shaft. A third gear on the second intermediate shaft is in engagement transmission with a fourth gear on the second intermediate shaft. A differential mechanism is provided with a fifth gear. The third gear is in engagement transmission with the fourth gear, and the fourth gear is in engagement transmission with the fifth gear at the same time. According to the transversely-arranged double-power-source vehicle driving assembly, on the one hand, the longitudinal size of the driving assembly is shortened, and the driving assembly is suitable for compact-structure vehicles, and on the other hand, the number of the used gears is small, so that the transmission structure is simplified.

Description

technical field [0001] The invention relates to a vehicle drive assembly with double power sources in transverse position, which is connected with the front axle or the rear axle of the vehicle and used for driving the 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] In the current vehicle powertrain, the power source, clutch, gearbox or reducer, an...
