Abstract:
1. A safety steering mechanism for an automobile, the mechanism comprising: a steering wheel mechanism changing a direction of a movement of an automobile; a jack connected to an automobile wheel providing a backward and forward movement of an axle with respect to a movement of the steering wheel; a hydraulic pump providing a hydraulic stream; a control valve controlling a direction of motion of the hydraulic stream; a plurality of directional control valves cutting the hydraulic stream between the control valve and the jack, and wherein the plurality of directional control valves includes a main valve and at least a pair of two position two port valve (2/2 valve), and wherein the main valve is a three position two-port valve, and wherein the main valve controls a backward and forward motion of the jack; a plurality of sensors measuring a tire pressure, wherein at least one sensor is installed on each tire of the automobile to generate signals corresponding to a tire pressure; a plurality of electronic units processing signals from the plurality of the sensors and passing an output signal to an electronic control unit (ECU) of the automobile, and wherein the plurality of the electronic units are provided in the plurality of the directional control valves; wherein the plurality of sensors installed in a plurality of tires are adapted to function in conjunction with a steering wheel of the automobile, and wherein the plurality of sensors installed in the tires of the automobile notify a tire blowout by sending an electronic signal to the plurality of electronic units, wherein the ECU sends an electronic command to the plurality of directional control valves to cut the hydraulic stream movement between the control valves and the jack and deviate the hydraulic stream to the main valve based on a detection of a decrease tire pressure of at least one tire and the main valve locks the jack from a backward and forward movement due to an effecting force caused by a variation in a tire pressure.
