COUPLING STRUCTURE OF MULTIPLE DRIVING DEVICES FOR NEW ENERGY ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/057295
Kind Code:
A1
Abstract:
Disclosed is a coupling structure of multiple driving devices for a new energy electric vehicle. The cylindrical surfaces of a first planetary gear housing and a second planetary gear housing are provided with teeth. The teeth on the cylindrical surface of the first planetary gear housing are engaged with the teeth on the cylindrical surface of the second planetary gear housing. The teeth on the cylindrical surface of the second planetary gear housing are engaged with the side gear of a differential. A planetary gear carrier is provided inside the both axial sides of the first planetary gear housing and the second planetary gear housing. A plurality of first planetary gears and first sun gears are mounted on each planetary gear carrier. A clutch device is provided between each planetary gear carrier and a housing assembly. The beneficial effects of the present invention are: in a pure electric mode, a high-power slow-speed motor can be used to start a vehicle or the high-power slow-speed motor and a medium-power high-speed motor can be started together to start the vehicle; cruising is performed with a low-power high-speed motor to achieve the purpose of saving energy and increasing cruising mileage.
