Embodiment Construction

[0072] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0073] like figure 1 As shown, the electric drive axle system based on the dual-clutch automatic transmission provided by the present invention includes: a motor part, a transmission part, a differential part and a half shaft part.

[0074] Wherein, the drive motor of the motor part is arranged on one side in the transmission housing, including: a drive motor shaft 130, a stator 110 and a rotor 120, wherein the stator 110 of the drive motor is connected with the transmission housing 100 through interference fit, and the drive motor shaft 130 There is a bearing 131 between the casing and the driving motor. When driving, the driving motor is in the motor mode. When braking, the driving motor is in the generator mode. The intermediate shaft 330 is rotatably supported in the tran...

Abstract

The invention discloses an electric driving bridge system based on a dual-clutch automatic transmission. The electric driving bridge system comprises a transmission shell, an intermediate shaft which is rotationally supported in the transmission shell, a driving motor which is arranged on one side in the transmission shell and comprises a driving motor output shaft, a first planet gear transmission mechanism which is connected to a driving motor shaft and is fixed to the middle portion in the transmission shell, an intermediate transmission disk which is rotationally arranged on the intermediate shaft in a sleeving manner, a first clutch which is connected with a planet carrier of the first planet gear transmission mechanism and is selectively connected with the intermediate transmission disk, a second clutch which is connected with the driving motor output shaft and is selectively connected with the intermediate transmission disk, and a differential mechanism which is connected with the intermediate transmission disk and comprises a first output shaft and a second output shaft, and the differential mechanism outputs the output power generated after speed changing through the first output shaft and the second output shaft. The invention further provides a control method of the electric driving bridge system based on the dual-clutch automatic transmission.

Description

technical field [0001] The present invention relates to an electric drive axle system, in particular to an electric drive axle system based on a dual-clutch automatic transmission and an electric drive control method based on a dual-clutch automatic transmission. Background technique [0002] Electric vehicles are new, energy-saving and environmentally friendly vehicles, especially in today's environment with severe air pollution, they have great development potential and broad application prospects. An electric vehicle uses an electric motor to replace the engine of a traditional car. The electric motor can be started with load and can meet the requirements of the car through reasonable configuration, which is a big difference from the engine. It is no longer suitable to use multi-speed transmissions on electric vehicles, but if the variable speed transmission device is cancelled, it will be difficult to meet the requirements of vehicle climbing and high-speed driving, espe...
