Problems solved by technology

As a type of hybrid electric vehicle, the extended-range hybrid electric vehicle is widely used because it can realize the fuel engine to drive the generator to generate electricity and provide power for the power battery. However, in the currently used extended-range hybrid scheme, the power generation The electric motor can only be used for power generation. Therefore, in order to achieve hybridization, the extended-range hybrid solution needs to configure a separate generator on the original drive system, which increases the cost of the electric vehicle, and the motor has a single function.

Embodiment 1

[0108] In the present application embodiment, the electric vehicle drive system includes a first motor 31, a second motor 32, an engine 33, a first connecting assembly 34, a second connection assembly 35, a third connecting assembly 36, a first differential, and The second differential speed 38.

[0109] Wherein, the first connection assembly 34 includes a first linear row 341 and a first clutch 342; the second connection assembly 35 includes a first transmission 351 and a second clutch 352; the third connection assembly 36 includes a seventh transmission 361.

[0110] Wherein, the first transmission 351 can be a reduction, or a glow. It should be noted that the first transmission 351 may be a single-port transmission or a multi-speed transmission. Wherein, the first transmission 351 can be a fixed axis, or a planetary wheel.

[0111] When actually use, the device in the first connection assembly 34 and the second connection assembly 35 has a variety of connection modes, and the s...

example 1

[0113] See Figure 4 As shown, the ring gear of the first line of star row 341 is connected to the engine 33 through the first clutch 342, and the sun gear of the first row star line 341 is connected to the first motor 31; the first stage gear of the first transmission 351 and the first line of star 341 The ring gear is connected, the second stage gear of the first transmission 351 is connected to the first differential speed 37; the second clutch 352 is coupled between the first stage gear and the second stage gear of the first transmission 351; seventh transmission The first stage gear of 361 is connected to the second electrode 32, and the second stage gear of the seventh transmission 361 is connected to the second differential 38.

[0114] It should be understood that when the first clutch 342 is engaged, the engine 33 is connected to the first linear star 341, the power output of the engine 33 can be transmitted to the first motor 31 through the first line of star 341, and thr...

Abstract

According to an electric automobile driving system and an electric automobile, the driving flexibility of the electric automobile can be improved while the mileage of the electric automobile is increased. The electric automobile driving system comprises a first motor, a second motor, an engine, a first connecting assembly, a second connecting assembly, a third connecting assembly, a first differential mechanism and a second differential mechanism. The engine is connected with the first motor through the first connecting assembly and connected with the first differential mechanism through the second connecting assembly and / or the first connecting assembly. The first motor is connected with the first differential mechanism through the second connecting assembly; the second motor is connected with the second differential mechanism through the third connecting assembly; the first differential mechanism is used for being connected with a first drive axle, and the first drive axle drives first side wheels; the second differential mechanism is used for being connected with a second drive axle, and the second drive axle drives second side wheels.

Description

Technical field [0001] The present application relates to the field of automotive technology, and in particular, there is an electric vehicle drive system and an electric vehicle. Background technique [0002] As the energy and environmental problems have become increasingly prominent in recent years, fuel as energy vehicles have been restricted and impact. Electric vehicles are powered by power batteries, compared to traditional fuel vehicles with high energy saving, low pollution, and high efficiency, so it has developed rapidly in recent years. [0003] Since the power battery of the electric vehicle is limited, when the electric vehicle is running, if a charging pile is provided on the travel path or set a small amount of charging pile, it will affect the normal driving of the electric vehicle. In order to ensure the normal driving of the electric vehicle, the fuel apparatus can be added to the electric vehicle to provide power for electric vehicles. The increased range mixed...
