The invention provides an in-wheel motor driving device mounted on an automobile. A gear box of the hub motor driving device accommodates a first helical gear/a second helical gear, has a first opening in an inner side wall through which a motor main shaft passes, and has a second opening in an outer side wall through which an axle passes. The hub motor driving device further comprises a first thrust bearing which is mounted on the outer side wall and supports the first helical gear, and a second thrust bearing which is mounted on the inner side wall and supports the second helical gear. The orientation of the helical teeth of the first helical gear/the second helical gear is set such that the first helical gear receives a thrust load toward the outside in the vehicle width direction and the second helical gear receives a thrust load toward the center side in the vehicle width direction when the vehicle advances.
本发明提供一种搭载于汽车的轮毂电机驱动装置。轮毂电机驱动装置的齿轮箱收容第一斜齿轮/第二斜齿轮,在内侧壁具有供电机主轴通过的第一开口,在外侧壁具有供车轴通过的第二开口。轮毂电机驱动装置还具备安装于外侧壁且支承第一斜齿轮的第一推力轴承和安装于内侧壁且支承第二斜齿轮的第二推力轴承。第一斜齿轮/第二斜齿轮的斜齿的朝向被设定为,在该汽车前进时,第一斜齿轮承受朝向车宽方向外侧的推力载荷,第二斜齿轮承受朝向车宽方向中央侧的推力载荷。
