Embodiment 1
[0036] Such as figure 1 As shown, in Embodiment 1 of the present invention, a vehicle drive assembly with a single transverse power source is connected to the axle shaft. The vehicle drive assembly includes a power source and an automatic transmission 10, and the automatic transmission 10 is provided with an input shaft 20 , the power source is connected to the input shaft 20, and a differential 50 is arranged at the connection between the automatic transmission 10 and the axle shaft.
[0037] In Embodiment 1 of the present invention, the power source is the electric motor 70 , and the rotor shaft of the electric motor 70 is integrated with the input shaft 20 .
[0038] In the automatic transmission 10, a first intermediate shaft 31 is arranged parallel to the input shaft, a second intermediate shaft 32 is arranged in a direction coaxial with the input shaft 20, and a third intermediate shaft is arranged coaxially with the first intermediate shaft 31. 33 , a first clutch 41 i...
Embodiment 2
[0052] In Example 2 of the present invention, as figure 2 As shown, the power source is the combination of the engine 61 and the ISG motor 62. On the one hand, the idling loss and pollution of the engine are reduced, and on the other hand, the ISG motor acts as a generator, which can regenerate power, recover energy, and achieve energy saving effects. .
[0053] Other contents of Embodiment 2 of the present invention are the same as Embodiment 1, and will not be described again here.
Embodiment 3
[0055] In Example 3 of the present invention, as figure 2 As shown, a torsional damper 63 is provided between the engine 61 and the ISG motor 62, which has a buffering function and reduces the torsional stiffness of the junction between the engine and the ISG motor, thereby reducing the natural frequency of torsional vibration and eliminating torsional vibration.
[0056] Other contents of Embodiment 3 of the present invention are the same as Embodiment 1, and will not be described again here.

Abstract
The invention discloses a horizontally-arranged single-power source vehicle drive assembly. The horizontally-arranged single-power source vehicle drive assembly comprises a power source and an automatic transmission, a first intermediate shaft is parallelly arranged on an output shaft of the automatic transmission, a second intermediate shaft and a third intermediate shaft are arranged in the direction coaxial to an input shaft and the first intermediate shaft respectively, a first clutch is arranged between the first intermediate shaft and the third intermediate shaft, and a second clutch is arranged between the input shaft and the second intermediate shaft. A first gear on the input shaft and a second gear on the first intermediate shaft are in meshing transmission; a third gear on the second intermediate shaft and a fourth gear on the third intermediate shaft are in meshing transmission, and a fifth gear on the third transmission and a sixth gear on a differential mechanism are in meshing transmission. According to the horizontally-arranged single-power source vehicle drive assembly, the transmission with two kinds of speed ratios can be achieved, the transmission form is flexible, the longitudinal dimension of the drive assembly is shortened, and the horizontally-arranged single-power source vehicle drive assembly is applicable to vehicles with compact type structures; meanwhile, due to fact that the quantity of gears adopted in the horizontally-arranged single-power source vehicle drive assembly is small, the transmission structure is simplified.
Description
technical field [0001] The invention relates to a vehicle drive assembly with a single horizontal power source, 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, and drive sha...
