Automotive steering assembly

摘要

An automotive steering assembly which has a steering pad maintained stationary independently of the steering wheel operation is disclosed. The assembly employs a sun and planetary gear system in transmission of rotary motion to the steering shaft. The steering wheel is rigidly attached to the steering shaft while the sun and planetary gear system contributes to maintenance of the orientation of the steering pad. In the sun and planetary gear system, the role of the sun portion is played by a timing belt whereas that of the planetary portion is played by a rotary gear wheel. The above timing belt and planetary gear wheel are adapted to be disengaged from each other upon entry of foreign matters including sand grains or the like.
