Abstract
The present invention relates to a device for increasing the energy efficiency of a vehicle using a spring, which accumulates rotating forces of wheels into an elastic energy of the spring during braking or deceleration of the vehicle, and reuses the elastic energy accumulated in the spring as auxiliary rotating forces for driving the wheel shafts during starting or acceleration of the vehicle, thereby increasing the energy efficiency and improving the fuel efficiency of the vehicle at the same time. The device for increasing the energy efficiency of a vehicle using a spring according to the present invention includes: a first sensor installed on the brake pedal of the vehicle to sense whether or not the brake pedal is pressed; a second sensor installed on the accelerator pedal of the vehicle to sense whether or not the accelerator pedal is pressed; a third sensor installed on a wheel shaft of the vehicle to sense the rotations per unit of time; a rotary shaft rotatably installed on one side of the wheel shaft; a spring installed on the rotary shaft such that the spring is wound by the rotation of the rotary shaft during braking or deceleration of the vehicle and rotates the rotary shaft by a restored elasticity during starting or acceleration of the vehicle; a fourth sensor installed in the spring to sense whether the spring is restored or not by detecting pressure according to the operation of the spring; a controller installed in the vehicle to receive signals from the first sensor, the second sensor, the third sensor, and the fourth sensor and generate a control signal; and an electric driving unit which is interposed between the wheel shaft and the rotary shaft, and which interlocks the wheel shaft and the rotary shaft such that in accordance with the control signal received from the controller, the rotating force of the wheel shaft can be transmitted to the rotary shaft to accumulate an elastic energy in the spring during braking or deceleration of the vehicle and the reverse rotating force of the rotary shaft generated by the restoration of the elastic force of the spring can be converted into a forward direction to transmit auxiliary rotating force to the wheel shaft during starting or acceleration of the vehicle, and which separates the wheel shaft and the rotary shaft from each other such that they are not interlocked with each other immediately after the restoration of the spring.
