Abstract

The invention discloses a commercial vehicle double-motor three-stage transmission electric drive axle assembly, and belongs to the field of new energy commercial vehicle electric drive axle assemblies, the commercial vehicle double-motor three-stage transmission electric drive axle assembly comprises two sets of motors and two sets of speed reducer systems, a first drive motor drives a first speed reducer assembly to transmit power, and a second drive motor drives a second speed reducer assembly to transmit power; and the two transmit power to the differential mechanism together, and transmit the power to left and right wheels through left and right half shafts to drive the vehicle to run. The two speed reducer assemblies respectively adopt three-stage transmission, so that larger torque is transmitted at a large speed ratio; each speed reducer is provided with two gears for a user to select and shift gears, so that the transmission efficiency is higher; the system is longitudinally arranged and is symmetrical about a half shaft, so that the production cost is saved, the production period is shortened, and the suspension arrangement space can be increased to adapt to different suspension systems; under the condition that the center distance is not changed, the spatial positions of the three shafts of the single speed reducer can be adjusted, and different whole vehicle arrangement requirements can be met.

Description

technical field [0001] The invention belongs to the technical field of electric drive axle assemblies of new energy commercial vehicles, and relates to an electric drive axle assembly of double-motor three-stage transmission for commercial vehicles. Background technique [0002] Traditional fuel commercial vehicles have made an indelible contribution to economic development, but at the same time, the problem of environmental pollution caused by large displacement is also very serious. The development of new energy commercial vehicles is imminent, and the technology of motor-driven transmission to form an electric drive axle is an important The new energy vehicle technology is more and more favored by auto workers. Compared with traditional fuel vehicles, electric drive axles are superior to traditional fuel vehicles in terms of emissions, but the power of the electric drive axle assembly is small, resulting in low transmission efficiency, and the vehicle layout space is smal...
