WHEEL SUPPORT DEVICE

摘要

A wheel support device (200), comprising springs (302, 304) fitted to an in-wheel motor (70) and damping the vibration of a motor-driven wheel (100) and the in-wheel motor (70) by extending and retracting, a knuckle (180) mounted on the springs (302, 304) and rotatably supporting the motor-driven wheel (100), the center part (306) of a dynamic mass damper mechanism (300) vibrating together with the in-wheel motor (70) by a force given from a road surface when a vehicle runs, the upper part (310) thereof restricting the vibration of the in-wheel motor (70) by coming into contact with the center part (306) at a specified portion, and cushioning members (322, 324) fitted to the portions of the center part (306) or the upper part (310) corresponding to the specified portions brought into contact with each other.
