Title:
TWO-GEAR TRANSMISSION ELECTRIC WHEEL
Document Type and Number:
WIPO Patent Application WO/2023/060980
Kind Code:
A1
Abstract:
The present application provides a two-gear transmission electric wheel, comprising a driving motor, a two-gear transmission mechanism, a housing, a rim, and a main shaft. The housing wraps the driving motor and the two-gear transmission mechanism; the two-gear transmission mechanism comprises a planetary gear assembly, a first disc brake, and a second disc brake; a first oil path leading to the first disc brake is formed in the housing; a second oil path leading to the second disc brake is provided in the main shaft; a rotor of the driving motor is transmitingly connected to a power input end of the planetary gear assembly; the rim is transmitingly connected to a power output end of the planetary gear assembly; the started first disc brake and the closed second disc brake enable the planetary gear assembly to work in a first-gear mode; and the started second disc brake and the closed first disc brake enable the planetary gear assembly to work in a second-gear mode. The electric wheel of the present application facilitates improvement in the power performance of the whole vehicle, and achieves the heat dissipation of a driving system.
