Abstract

The invention discloses an electric driving transmission system for an electric vehicle. The electric driving transmission system comprises a driving shell, wherein an input shaft sub-assembly, an output shaft sub-assembly and a differential mechanism sub-assembly are arranged in the driving shell; the input shaft sub-assembly is matched with the output shaft sub-assembly; the output shaft sub-assembly is matched with the differential mechanism sub-assembly. The electric driving transmission system is technically characterized in that a brake mechanism sub-assembly is further arranged in the driving shell; the differential mechanism sub-assembly comprises a differential mechanism driven gear meshed with shaft teeth of an output shaft and a differential mechanism positioned in the differential mechanism driven gear; the brake mechanism sub-assembly comprises a gear-shifting arm, a parking control shaft, a gear-shifting disk with four gear grooves, a lock rod which is limited in the driving shell and is provided with a V-shaped block, a plate spring which is fixed in the driving shell and is matched with the gear-shifting disk, a pawl rotating shaft which is limited in the driving shell, and a pawl which is fixed on the pawl rotating shaft. The problems that an existing electric vehicle transmission mechanism is short in maintenance period, short in service life, low in operation stability, poor in sealing property during high rotating speed, likely to burn and the like are fundamentally solved.

Description

technical field [0001] The present invention relates to the field of electric vehicle drive system, in particular to a gear-rotating device for electric drive [0002] A vehicle transmission characterized by its arrangement, location or type, specifically an electric drive transmission system for an electric vehicle. Background technique [0003] As we all know, the electric drive transmission system is an important part of the electric vehicle. With the continuous increase of the dual pressure of oil resources and the environment, the development of new energy vehicles has become the direction of the future development of the automotive industry. New energy vehicles mainly include pure electric vehicles, plug-in hybrid vehicles and fuel cell vehicles. Feedback and other characteristics, so it does not require clutches and transmissions, and is replaced by electric drive transmission systems. With the rapid development of new energy vehicles, electric drive transmission sy...
