Abstract

The invention discloses a multi-mode dual-motor coupling electric drive axle, which comprises a main motor; an auxiliary motor; a differential; a housing; a front end cover; a rear end cover; a first half shaft; A second half shaft; a main speed reducer; a power coupling mechanism; a TV coupling mechanism; a first clutch which is used for realizing separation and combination of a third sun gear and a third planet carrier of the TV coupling mechanism; a second clutch which is used for realizing separation and combination of the first half shaft and the third sun gear; and a third clutch which is used for realizing separation and combination of the shell of the differential mechanism and the second planet carrier of the dynamic coupling mechanism. The multi-mode dual-motor coupling electric drive axle has four working modes including a main motor independent drive mode, a torque directional distribution mode, a dual-motor torque coupling drive mode and a dual-motor rotating speed coupling drive mode, and by controlling the working states of the first clutch, the second clutch and the third clutch, the working modes can be switched, so that the multi-working-condition driving requirement of the automobile is met.

Description

technical field [0001] The invention belongs to the field of electric vehicle transmission, in particular to a multi-mode dual-motor coupling electric drive axle with torque orientation distribution function. Background technique [0002] Thanks to the advantages of good emission characteristics, high integration, fast motor response, and high control accuracy, electric vehicles have developed rapidly in recent years. However, compared with foreign electric vehicle manufacturers such as Tesla, there is still a certain gap in domestic high-performance electric vehicle related technologies. [0003] At present, there are two driving forms of electric vehicles: centralized drive and distributed drive. Although distributed drive may be the future development direction due to its significant advantages, due to technical limitations and cost constraints such as materials and processes, centralized drive will still be the mainstream form of drive at present and for a period of tim...
