摘要： A four wheel steering system for a motor vehicle with steerable front and rear road wheels, a steering angle sensor for detecting a front wheel steering angle through which the front road wheels are steered, a vehicle speed sensor for detecting a vehicle speed of the motor vehicle, a rear wheel steering mechanism for steering the rear wheels, and a controller for controlling the rear wheel steering mechanism to steer the rear road wheels based on the detected front wheel steering angle and the detected vehicle speed when the front road wheels are steering. The controller controls the rear wheel steering mechanism to steer the rear road wheels in a direction which is opposite to the front road wheels if the detected vehicle speed is relatively low, and also controls the rear wheel steering mechanism to steer the rear road wheels in a direction which is the same as the front road wheels if the detected vehicle speed is relatively high. Furthermore, the controller controls the rear wheel steering mechanism to increase a rear wheel steering angle which through the rear road wheels are steered as the front wheel steering angle increases if a change in the front wheel steering angle is relatively small, and controls the rear wheel steering mechanism to reduce an increase in the rear wheel steering angle if a change in the front wheel steering angle is relatively large.

摘要： 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.

摘要： This invention relates to an improvement in a pneumatic tire for construction vehicles. The improved tire makes use of a steel cord breaker, but can prevent mechanical and thermal separations in the tire. Breaker rubberized cords are designed to have a gap ratio given by ##EQU1## preferably 0.72 to 0.80, for the purpose of restraining the mechanical separation, where D is a distance between centers of two adjacent cords and d is a diameter of the cord. A tread rubber layer is designed to have a ratio R of a skid base S to a tire section height H given by ##EQU2## FOR THE PURPOSE OF RESTRAINING THE THERMAL SEPARATION.
