Embodiment 1

[0017] see figure 1 , a multi-motor front and rear drive electric vehicle described in the embodiment of the present invention is a four-wheel (two front wheels 7 and two rear wheels) electric vehicle, the electric vehicle is provided with a front and rear drive device, and the front and rear drive device It is mainly composed of a main motor 1, an auxiliary motor 2, a controller 3, a fuel generator 4 and a storage battery 5; wherein, the main motor 1, the auxiliary motor 2 and the fuel generator 4 are all conductively connected to the controller 3, The input end and the output end of the storage battery 5 are respectively electrically connected with the fuel generator 4 and the controller 3; moreover, the main motor 1 is in drive connection with the rear wheel drive shaft 6 of the electric vehicle, and the auxiliary motor 2 It is a hub motor, and is located on the two front wheels 7 of the electric vehicle, and is connected with the front wheels 7 by driving.

[0018] The wo...

Embodiment 2

[0021] see figure 2 , the structure of a multi-motor front and rear drive electric vehicle described in the embodiment of the present invention is basically the same as that of the first embodiment, and the front and rear drive devices are also provided. The front and rear drive devices are mainly composed of a main motor 1, an auxiliary motor 2, and a controller 3. , a fuel generator 4 and a storage battery 5, and their connection relationship is basically the same as in Embodiment 1, and will not be repeated here. The only difference is that the electric vehicle is a three-wheeled electric vehicle, including a front wheel 7 and two rear wheels (or two front wheels and a rear wheel), and the auxiliary motor 2 is a direct-current counter-charged vehicle. A permanent magnet motor, the output end of the DC permanent magnet motor is conductively connected with the storage battery 5 . In this way, the electric car can also realize switching between rear-wheel drive and front-whe...

Embodiment 3

[0023] see image 3 , the structure of a multi-motor front and rear drive electric vehicle described in the embodiment of the present invention is basically the same as that of the first embodiment, and the front and rear drive devices are also provided. The front and rear drive devices are mainly composed of a main motor 1, an auxiliary motor 2, and a controller 3. , a fuel generator 4 and a storage battery 5, and their connection relationship is basically the same as in Embodiment 1, and will not be repeated here. Its difference is only: this electric vehicle mostly is the electric bus or the electric truck of six wheels (also can more than six wheels), comprises four front wheels 7 and two trailing wheels.

[0024] The electric vehicle of the present invention can be an electric vehicle with more than three wheels.

Abstract

The invention relates to a multi-motor front and rear drive electric vehicle which is provided with front and rear drive devices and mainly comprises a master motor, auxiliary motors, a controller, a fuel generator, a battery and a rectifier bridge circuit module. The master motor, the auxiliary motors and the fuel generator are all connected with the controller in a communicated manner. Input and output ends of the battery are electrically connected with the fuel generator and the controller respectively. The master motor is in drive connection with a rear wheel drive shaft of the electric vehicle. The auxiliary motors are arranged on front wheels of the electric vehicle and are in drive connection with the front wheels. Input and output ends of the rectifier bridge circuit module are connected with the auxiliary motors and the battery respectively in a communicated manner. Therefore, rear wheel drive and rear wheel drive can be switched, driving is flexible and convenient, the electric vehicle can be charged anytime and anywhere, operation and using are convenient and flexible, driving distance is long, drive kinetic energy of the electric vehicle can be converted into electric energy effectively, the fuel generator is used less frequently, oil consumption is lower, and energy conservation and environment protection are achieved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles and relates to a multi-motor front and rear drive electric vehicle. Background technique [0002] At present, the world is facing two major problems of increasing energy shortage and deteriorating environment, so the slogan of energy saving and emission reduction has been launched around the world. For this reason, electric vehicles are welcomed by consumers for their energy-saving and environmental protection performance and low price; however, the existing electric vehicles are all pure electric, and the power is extremely limited, resulting in short driving distances, which cannot meet people's long-distance driving needs. Require. Contents of the invention [0003] In order to solve the above-mentioned problems existing in the prior art, the present invention provides a rear-wheel drive and front-wheel rear-wheel drive switching, flexible and convenient driving, and can also charg...
