Problems solved by technology
[0002] Due to the influence of the drive axle space, the electric drive axle system is generally made into a transmission structure with a fixed reduction ratio, which will affect the operating efficiency of the motor, and it is difficult to make the motor operate in a high-efficiency operating range in a large speed range
At present, the electric drive axle will cause power interruption during the shifting process, especially for vehicles with a single drive axle, the power interruption on the uphill will cause psychological pressure on the driver, and there are potential safety hazards

An electric drive axle system is provided. The system comprises: a first input unit; a second input unit; an intermediate shaft, which is sleeved on a first output half shaft in a relatively rotating manner; an intermediate shaft gear, which is connected to the first end of the intermediate shaft and meshed with a first parallel shaft gears of the first input unit and the second input unit respectively; a first planet row, which comprises a first sun gear, a first planet gear, a first gear ring and a first planet carrier, wherein the first sun gear is connected to the second end of the intermediate shaft; and a differential mechanism, which comprises a differential mechanism shell, a first output end and a second output end, wherein the differential mechanism shell is connected with the first planet carrier, the first output end is connected with the first output half shaft, and the second output end is connected with the second output half shaft. The requirement for a large reduction ratio and gear shifting without power interruption can be met, the double motors are arranged externally, the size of a single motor can be reduced, and maintenance of the motors is facilitated.
Description
technical field [0001] The invention relates to the field of machinery and vehicle transmission, in particular to an electric drive axle system. Background technique [0002] Due to the influence of the drive axle space, the electric drive axle system is generally made into a transmission structure with a fixed reduction ratio, which will affect the operating efficiency of the motor, and it is difficult to keep the motor in a high-efficiency operating range in a large speed range. At present, the electric drive axle will cause power interruption during the gear shifting process. Especially for vehicles with a single drive axle, the power interruption on uphill will cause psychological pressure on the driver and pose a safety hazard. [0003] Therefore, it is necessary to study an electric drive axle system to solve one or more technical problems mentioned above. Contents of the invention [0004] In order to solve at least one of the above technical problems, according to...
