Title:
IN-WHEEL ELECTRIC MOTOR DRIVING SYSTEM, AND MOTOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/130242
Kind Code:
A1
Abstract:
Provided is an in-wheel electric motor driving system, comprising a steering knuckle (1), a driving mechanism (2), a wheel bearing (3) and a brake system (4). In the axial direction (A) of an output shaft (24) of the driving mechanism (2), the driving mechanism (2) is located on one side of the steering knuckle (1), and the wheel bearing (3) and the brake system (4) are located on the other side of the steering knuckle (1). An outer ring (32) of the wheel bearing (3) is detachably mounted on the steering knuckle (1); an inner ring (31) is in transmission connection with the output shaft (24) by means of a spline; and a brake caliper mechanism of the brake system (4) is detachably mounted on a mounting portion (11). The above structural designs all aid the structures, such as the steering knuckle, of the in-wheel electric motor driving system of the present application in adapting to and being assembled with and disassembled from different brake systems and wheel bearings, thereby improving the universality of the in-wheel electric motor driving system of the present application. Further provided is a motor vehicle, comprising the in-wheel electric motor driving system.
