Abstract

The invention discloses a double-motor horizontal electric drive axle assembly system and a shift control method. The system includes: drive motor I, input shaft I, input shaft I gear, coupling sleeve I, intermediate shaft, intermediate shaft gear I, intermediate shaft gear II, intermediate shaft gear III, three-axis gear, coupling sleeve II, input shaft Ⅱ gear, driving motor Ⅱ, input shaft Ⅱ, three shafts, driving half shaft, differential, differential gear, driving wheel, spline connection A, spline connection B. The method comprises the following steps: Step 1, the dual-motor low-speed gear changes to the dual-motor high-speed gear; Step 2, changes from the dual-motor high-speed gear to the dual-motor low-speed gear; Braking control in the gear mode; the advantages of the present invention are: the power output can be allocated reasonably, the power is saved, the effect of energy saving and environmental protection is achieved, the waste of electric energy is avoided, and the battery cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a dual-motor transverse electric drive axle assembly system and a shift control method.
