Steering equipment for road vehicle - has front and rear wheel steering controlled by feedback with slewing rate as parameter

摘要

The rear-wheel steering device (10) contains a mechanism (18), which is connected mechanically via a transmission shaft (52) with the front wheel steering mechanism (14) for steering the front wheels (12). The rear-wheel steering mechanism steers the rear wheels blocked by the front wheel steering mechanism (14) so that a predetermined theoretical value for the rear wheel steering angle is achieved corresp. to the front wheel steering angle (theta F). The rear-wheel steering device (10) also contains a mechanism (20) for adjustment of the steering angle ratio, which is provided in the rear-wheel steering mechanism (18), and which adjusts and varies a steering angle ratio through the ratio of the front wheel steering angle to that of the rear-wheels. USE/ADVANTAGE - To stabilise movement of road vehicle with front and rear wheel steering.
