Problems solved by technology
[0004] However, the current new energy vehicles are driven by a single motor, and the power is weak, which cannot meet the driving force under different loads.
If two motors are used to drive, it is easy to cause the two motors to be unable to effectively couple the power, and the effect of boosting power cannot be achieved.
And if only a single gear is used to drive new energy vehicles, the driving experience will be greatly reduced

The invention provides an integrated double-motor two-gear electric drive axle assembly mechanism and a driving method. The integrated double-motor two-gear electric drive axle assembly mechanism comprises an axle housing assembly, a front speed reduction assembly, a rear speed reduction assembly, a brake assembly and two driving motors arranged on the axle housing assembly. The axle housing assembly comprises an axle housing, shaft heads and a brake flange; the shaft heads are arranged at two ends of the axle housing; a hub is mounted on each shaft head; the front and rear speed reduction assemblies and the brake flange are connected to the axle housing; the brake assembly is mounted on the brake flange; and the mounting position of the brake assembly is close to the position of the hub. By matching two sets of motors, different coupling of driving force under different vehicle speeds and different loads is realized; and the double motors share two gears for gear shifting, the output torque of the motors can be further increased while the gear shifting reliability is guaranteed, the motors work in a high-efficiency interval, and the dynamic property and economical efficiency are improved.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to an integrated dual-motor two-speed electric drive axle assembly mechanism and a driving method. Background technique [0002] At present, judging from the development trend of new energy vehicle electric drive system technology, the industry is developing towards the integration and integration of power systems. [0003] At present, in order to meet the needs of the use of new energy vehicles and improve the battery life of new energy vehicles, improving the vehicle dynamic performance and economic performance of new energy vehicles is an urgent problem to be solved. [0004] However, the current new energy vehicles are driven by a single motor, and the power is weak, which cannot meet the driving force under different loads. If two motors are used to drive, it is easy to cause that the two motors cannot effectively couple the power, and the effect of boosting power cannot be a...
