| 摘要 |
This in-wheel motor drive device (21) is provided with a motor unit (A), a decelerator unit (B), a wheel bearing unit (C), a casing (22), and a lubrication mechanism for supplying a lubricant to the motor unit (A) and the decelerator unit (B). A motor rotation shaft (24) of the motor unit (A) drives rotation of a decelerator input shaft (25), which has eccentric portions (25a, 25b); the decelerator unit (B) reduces rotation of the decelerator input shaft (25) and transmits said rotation to a decelerator output shaft (28); and the wheel bearing unit (C) is linked to the decelerator output shaft (28). In this in-wheel motor drive device (21), the motor unit (A) is configured from a stator (23a) fixed to the casing (22) and a rotor (23b) provided on the motor rotation shaft (24), and in the motor unit (A), a shielding plate (70) is provided which reduces stirring resistance of the lubricant generated by rotation of the rotor (23b). |
