ABSTRACT:
An electric power steering system which additionally includes a radial arm extending from a steering rod, an axial shaft extending in parallel with the axial center line of the steering rod, an axial bore formed in the casing of the system for guiding axial movement of the axial shaft substantially without any play, and a spring member urging the axial shaft against a side wall of the axial bore. Thus, rotation of the steering rod around its axial center line may be prevented with a relatively small force. Therefore, no excessive force needs to be applied to the axial shaft, and the axial shaft would not encounter any substantial resistance to its axial movement. The axial shaft may be provided with a groove extending along one side thereof in parallel with the axial central line of the axial shaft and provided with a bottom surface which slopes along its lengthwise direction, and the casing may support a steering rod displacement sensor having a spring-loaded retractable plunger serving as a measuring end and abutting the sloping bottom surface of the groove. Thus, the steering rod displacement sensor may be provided with a simple structure which makes it suitable to be mounted in a very limited space in the power steering system. If desired, the steering rod displacement sensor may also serve as the spring member for removing play between the axial shaft and its axial bore. This electric power steering system is suitable for use in front and rear wheel steering vehicles.
