STEERING DEVICE FOR WHEEL

摘要

A steering device basically includes an in-wheel motor drive wheel, a dedicated in-wheel motor drive unit, an upper side fixing seat, a lower side fixing seat and a steering mechanism. The dedicated in-wheel motor drive unit includes an electric motor as a power source. The dedicated in-wheel motor drive unit is integrated with the in-wheel motor drive wheel. The upper side fixing seat is disposed at an upper part of the dedicated in-wheel motor drive unit. The lower side fixing seat is disposed at a lower part of the dedicated in-wheel motor drive unit. The steering mechanism converts a steering force to a steering torque around a king pin axis and applies a torque to the in-wheel motor drive wheel. The steering mechanism is disposed in a location that is on the king pin axis and that is above the in-wheel motor drive wheel.
