Abstract

The embodiment of the invention provides an electric drive axle, an axle structure and an automobile, and relates to the field of automobiles. The electric drive axle comprises a planetary gear speedreduction mechanism, a first gear mechanism, a second gear mechanism and a gear shifting mechanism, wherein the planetary gear reducing mechanism is in transmission connection with a driving motor; the first gear mechanism and the second gear mechanism are located on the two sides of the planetary gear speed reduction mechanism respectively and are in transmission connection with the planetary gear speed reduction mechanism respectively, and the gear shifting mechanism is selectively connected with the first gear mechanism and the second gear mechanism and used for enabling the first gear mechanism or the second gear mechanism to be in transmission connection with the output end. The structure of the electric drive axle has the characteristics of small size and light weight, the assembly efficiency can be improved, and the assembly weight and cost are reduced.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an electric drive axle, an axle structure and an automobile. Background technique [0002] The existing large-speed ratio 2AMT electric drive axle assembly generally adopts a wheel-side reduction mechanism to reduce the load, specifications and gear stages of the central reduction mechanism; the wheel-side reduction mechanism is based on the existing traditional wheel-side reduction axle. On the top, the central reducer assembly is replaced with a parallel shaft structure motor belt reducer assembly. However, due to the reducer on the wheel side, its heating will affect the normal operation of the tire, and the high temperature may cause the tire to rupture. Contents of the invention [0003] Objects of the present invention include, for example, to provide an electric drive axle, an axle structure and a vehicle, which are characterized by small size and light weight, which can impr...
