Description

Four-wheel drive vehicle with independent electric power system for rear wheels The present invention relates to a four-wheel drive vehicle utilizing rear-wheel self-generation, and more specifically, to a vehicle that operates with an internal combustion engine, wherein a connecting shaft is provided through the rear wheel of the vehicle, the connecting shaft is connected to a belt rotating part attached to the center of the outer surface of the vehicle's floor, and a vehicle belt is provided that is connected to the belt rotating part and transmits power vertically upward, and the vehicle belt operates two generators mounted on the inner surface of the rear end of the vehicle to produce electricity and charge a battery, and the charged battery operates a front-wheel electric motor connected to the front wheel of the vehicle to rotate the front wheel of the vehicle, and also supplies electricity required for the vehicle. Most vehicles to date have operated by the explosive force of fuel combustion, and although there have been recent examples of electric vehicles that operate by charging electricity into a battery and then driving a motor using the power from that battery, in this case, the amount of power charged in the battery is depleted after a certain period of use and can no longer be used as power, so there was the inconvenience of having to always charge the battery in advance before the charge was completely depleted. Therefore, vehicles powered by such rechargeable batteries cannot operate when the battery charge is low or depleted during long-distance driving, which causes significant disruption to operation. Furthermore, since vehicle batteries require a large amount of power, charging alone takes a long time of 5 to 8 hours or more, resulting in significant inconvenience during operation due to the charging period and thus lacking practicality.
