Abstract

The invention discloses a quick drive device of a pure electric passenger vehicle. The device comprises a passenger vehicle body. A first motor and a second motor are installed at the bottom end inside the passenger vehicle body. The first motor is located on one side of the second motor. One end of the first motor and one end of the second motor are rotationally connected with driving gears through rotary shafts. One side of each driving gear is in engaged connection with a driven gear through a toothed groove. A drive groove is formed in the outer wall on one side of each driven gear. Each driving gear is located in the corresponding drive groove. Through arrangement of the first motor, the second motor, the drive grooves, the toothed grooves and the driving gears, when the electric passenger vehicle is started, the first motor and the second motor synchronously drive the passenger vehicle and drive the driving gears through the rotary shafts to rotate, the driving gears are engagedwith the toothed grooves in the drive grooves, so that the driven wheels are driven to rotate, and the two driven gears drive a first main output shaft and a second main output shaft to rotate correspondingly.

Description

technical field [0001] The invention belongs to the technical field of drive devices, and in particular relates to a fast drive device for pure electric passenger cars. Background technique [0002] The driving device of an electric bus is an important part of the chassis of an electric bus. Most or a part of the existing serial and parallel hybrid electric vehicles still retain the original chassis of internal combustion vehicles, that is, the use of couplings or transfer The drive motor is connected in series or in parallel with the engine of the original internal combustion vehicle, while in the driving device of the pure electric bus, the drive motor is connected to the transmission shaft by a coupling, so as to retain the main deceleration between the drive wheel and the motor Conventional transmission and connection parts such as gears, transmission shafts, couplings and keys ensure the integrity of the drive. [0003] However, although the driving device of the exist...
