<p>The present invention relates to a self-generation device for converting pressure energy produced by a vehicle load into electrical energy, the self-generation device being interposed between a hub bearing and a wheel hub in a front axle of a vehicle including a steering knuckle, the hub bearing, the wheel hub and a constant velocity joint sequentially connected, which comprises a first pressure applying means arranged inside the hub bearing, a second pressure applying means arranged inside the first pressure applying means so as to face the first pressure applying means, and a piezoelectric module interposed between the first and the second pressure applying means for generating a voltage according to a pressure varying with a vehicle load upon rotation of the shaft connected to the constant velocity joint. According to the present invention, the pressure energy produced by a vehicle load is converted into the electrical energy utilized as a power source of the vehicle, thus popularizing an electric vehicle because an electric vehicle battery may be continuously recharged to stably supply electricity.Furthermore, the present invention contributes to the reduction of environmental pollution resulting from excessive use of fossil energy and the problems of fossil energy exhaustion.</p> |
