Title:

IN-WHEEL MOTOR SYSTEM AND METHOD OF INSTALLING IN-WHEEL MOTOR

Document Type and Number:

WIPO Patent Application WO/2005/101984

Kind Code:

A2

Abstract:

A direct drive motor module has hollow-disk-like plates (21, 22) for coupling the rotation side of an in-wheel motor (3) and a wheel (2), and has a drive force transmission mechanism (20) with a cross guide (23) for guiding the plates (21, 22) in the vertical direction. To install the direct drive motor module on the wheel (2), installation holes (2s) are formed in spokes of the wheel (2), fixation sections of connection pins (30), whose pin head sections functioning as fitting sections have a spherical shape, are installed in the installation holes (2s), guide holes (40) having a predetermined clearance relative to the outer diameter of the pin head sections (33) are formed in a wheel side plate (22) supporting the wheel (2) side of the cross guide (23), the pin head sections of the connection pins (30) are fitted in the guide holes (40), and the direct drive motor module is installed on the wheel (2). The construction enables the direct drive motor module to be reliably installed on the wheel (2) even if assembly accuracy is not so high.
