DRIVE-BY-WIRE STEERING SYSTEMS HAVING A STOP MECHANISM

摘要

A drive-by wire steering system is provided. The steering system comprises a steering shaft and a stop mechanism. The steering shaft is configured for a first angular displacement about a first axis. The steering shaft comprises a first geared portion and a first end. The first end is connectable to a vehicle's steering wheel. The stop mechanism comprises a stop portion and a second geared portion. The stop portion defines a first position and a second position. The first geared portion and the second geared portion are operatively engaged such that angular displacement of the steering shaft imparts a second angular displacement about a second axis to the stop mechanism. The first angular displacement is limited when the second angular displacement is such that the steering shaft abuts the stop portion at either the first position or the second position.
