摘要： A motor vehicle steering system for steering rearward wheels as well as forward wheels. The steering system includes a sensor for sensing at least a turning motion of the motor vehicle, a computer for processing signals from the sensor, and an actuator controllable by the computer for steering the rearward wheels in order to meet driving conditions of the vehicle while turning, as much as possible. The sensor may comprise a lateral acceleration or yaw angular velocity sensor, or a combination of a steering angle sensor and a lateral acceleration or yaw angular velocity sensor, or a combination of a steering angle sensor and an acceleration and deceleration sensor, or the like. A steered angle ratio .gamma. of the rearward wheels to forward wheels is selected to be in the range of 0

摘要： A steering apparatus for vehicles which includes a pinion rotatably mounted on an arm movable longitudinally in response to turning movement of a steering wheel, and a pair of longitudinally movable racks held in meshing engagement with the pinion. One of the racks is operatively coupled with front wheels of the vehicle and with a pivot arm pivotable on a movable pivot which is displaceable along the pivot arm in response to vehicle speeds. The other rack is coupled through a pivotable lever with an arm which is pivotally mounted on the pivot arm and is operatively coupled with the rear wheels. When the steering wheel is turned, the front and rear wheels are turned in the same direction or in opposite directions, depending on the position of the movable pivot on the pivot arm, which position is a function of the vehicle speed. The front and rear wheels are turned in the same direction when the vehicle is running at a high speed, and in opposite directions when the vehicle is running at a low speed. The racks and pinion may be dispensed with and the front wheels operatively coupled only through a connecting rod pivotally connected to a pivot arm pivotally mounted on a movable pivot, the rear wheels being pivotally connected through an arm to the pivot arm.

摘要： A safety wheel designed so that when air sealed within a tire is lost, the vehicle may be supported by a flat protector and bead stopper members in place of air pressure within the tire. The safety wheel comprises a split rim, a tubeless tire mounted on the split rim, and a flat protector of an annular configuration. The flat protector is divided into a plurality of circular protector elements whose opposed opposite ends are connected with each other through the bead stopper members adapted to restrain relative movement between the bead portions of the tire and the split rim.
