Detecting whether it is transmitted to the controller 70 to be described later, it may be formed of various types of sensors according to the embodiment, it is formed on the brake pedal (3) is formed of a piezoelectric sensor for detecting the pressure desirable.

The signal transmitted from the first sensor 10 to the controller 70 will be described later by causing the electric unit 80 to interlock the wheel shaft 7 and the rotation shaft 40 in the same direction when the vehicle is braked or decelerated. It serves as one of the parameters for generating a control signal which causes the winding 50 to be wound.

A second sensor 20 is installed on the accelerator pedal 5 of the vehicle, and the second sensor 20 is accelerated for the actual start by the driver's intention by detecting whether the accelerator pedal 5 of the vehicle is pressurized.

Do.

The signal transmitted from the second sensor 20 to the controller 70 causes the transmission unit 80 to interlock the wheel shaft 7 and the rotation shaft 40 in different directions when the vehicle starts or accelerates. It acts as one of the parameters for generating a control signal such that the elastic rotational force of the rotary shaft 40 by 50) is transmitted to the auxiliary rotational force of the wheel shaft 7.

A third sensor 30 is installed on the wheel axle 7 of the vehicle, and the third sensor 30 is whether the actual vehicle is stationary or starting by sensing the number of revolutions per unit time of the wheel axle 7, or Detecting whether the vehicle is traveling at the low speed stage or the high speed stage and transmitting the same to the controller 70, which will be described later. However, the sensor 70 may be formed of various types of sensors, but it is installed on the wheel shaft 7. It is preferable that the encoder is formed of an encoder for detecting the rotation speed.

The signal transmitted from the third sensor 30 to the controller 70 will be described later by causing the electric unit 80 to interlock the wheel shaft 7 and the rotation shaft 40 in the same direction when the vehicle is braked or decelerated. It acts as one of the parameters for generating a control signal for winding the spring 50 to be wound, or when the vehicle starts or accelerates, the electric unit 80 rotates the wheel shaft 7 and the rotation shaft 40 in different directions. By interlocking with the spring 50 acts as one of the parameters for generating a control signal for transmitting the elastic rotational force of the rotary shaft 40 by the spring 50 to the auxiliary rotational force of the wheel shaft (7).

Rotating shaft 40 is rotatably installed on one side of the wheel shaft (7) of the vehicle, the rotary shaft 40 is rotated in conjunction with the wheel shaft (7) while winding or winding the spring 50 installed thereon By rotating the elastic force of the 50 to transmit the elastic rotational force to the wheel shaft (7) as a secondary rotational force, a bearing that is extended in parallel to one side of the wheel shaft (7) in the vehicle and fixed to the vehicle body (not shown) Is rotatably supported by

The spring 50 is installed on the above-described rotary shaft 40, which is wound by the rotation of the rotary shaft 40 when braking or decelerating the vehicle, accumulating braking energy in the form of elastic energy and starting the vehicle. At the time of acceleration or rotation, the rotary shaft 40 is rotated while elastically restored, one end of which is fixed to the rotary shaft 40 and the other end of which is fixed to the vehicle body (not shown).

Although the term spring 50 is used, the term includes all elastic members that vary in shape and size in which elastic energy can be accumulated with respect to rotation of the wheel shaft 7 in a predetermined direction.

The fourth sensor 60 is installed in the above-mentioned spring 50, and the fourth sensor 60 is restored to the original state of the spring 50 through the detection of the pressure according to the operation of the spring 50, that is, The presence of the elastic energy of the spring 50 is transmitted to the controller 70 to be described later, and may be formed of various types of sensors according to the embodiment, but is installed in the spring 50 and the spring 50 It is preferably formed of a piezoelectric sensor for sensing the pressure caused by winding and unwinding.

The fourth sensor 60 also causes the controller 70 to turn the wheels when a pressure above the set value is sensed in the spring 50 to prevent the spring 50 from being overwound and broken as excess elastic energy is accumulated. It generates a control signal for separating the shaft (7) and the rotating shaft (40) from each other.

The signal transmitted from the fourth sensor 60 to the controller 70 is started by the vehicle or shifted to the high speed stage, so that all the elastic energy of the mainspring 50 is transmitted to the auxiliary rotating power of the wheel shaft 7. When the motor unit 80 acts as one of the parameters for generating a control signal that separates the wheel shaft 7 and the rotation shaft 40 from each other. As the rotary shaft 40 is interlocked so as not to rotate, the spring 50 is prevented from being broken.

The controller 70 is installed in the vehicle, which is the first sensor 10, the second sensor 20, the third sensor 30, the fourth sensor 60 and the fifth to be described later. Receiving a signal from the sensor 100 to generate a control signal for operating the electric unit 80 described later, it is formed in the form of a printed circuit board in which a specific control circuit is implemented. The controller 70 may be included in the entire control unit (not shown) of the vehicle itself and may be integrally implemented, or may be formed separately from the entire control unit of the vehicle itself.

An electric unit 80 is installed between the above-described wheel shaft 7 and the rotating shaft 40, which is adapted to the wheel shaft during braking or deceleration of the vehicle according to a control signal received from the controller 70. The rotating force of (7) is transmitted to the rotating shaft 40 so that the spring 50 can be wound, and when the vehicle starts or accelerates, the reverse rotational power of the rotating shaft 40 by the elastic restoration of the spring 50 is forwarded. The wheel shaft 7 and the rotating shaft 40 are interlocked so that the auxiliary rotational force is transferred to the wheel shaft 7, and the rotation of the wheel shaft 7 is not transmitted to the rotating shaft 40 while the vehicle is running. ) And the rotation shaft 40 serves to block interlocking.

The electric unit 80 is interlocked so that one axis is rotated in the same direction with respect to one axis with respect to one axis, or the other axis is rotated in a different direction with respect to one axis, or Or, it may be implemented as a plurality of gearboxes similar to a kind of transmission having three transmission modes such that only one shaft is rotated. In this case, the electric unit 80 is integrally formed on the wheel shaft 7 and the rotation shaft 40, respectively. It includes a gear installed. The transmission unit 80 also preferably includes a disc clutch (not shown) for gear protection according to the rotation rate in the process of outputting the output shaft to the wheel shaft.

For example, when the braking or deceleration of the vehicle is performed, only one gear is interposed between the wheel shaft 7 and the rotation shaft 40 so that the rotation shaft 40 is in the same direction as the rotation direction of the wheel shaft 7. Winding the spring 50 by interlocking with the rotation, and when the vehicle starts or accelerates, two gears are interposed between the wheel shaft 7 and the rotating shaft 40 to rotate the shaft 40 by the elastic energy of the spring 50. The reverse rotation of the rotation is interlocked to be rotated in different directions so as to be transferred to the wheel shaft (7), and when the elastic energy of the spring 50 is exhausted, the rotary shaft 40 against the rotation of the wheel shaft (7) It is preferable to be configured not to interlock.

When the vehicle starts or accelerates, the auxiliary rotational force of the rotating shaft 40 transmitted to the wheel shaft 7 by the aforementioned electric unit 80 is preferably greater than the rotation force of the wheel shaft 7. When the auxiliary rotational force of the rotation shaft 40 transmitted to the wheel shaft 7 by the aforementioned electric unit 80 during acceleration is smaller than the rotation force of the wheel shaft 7, the rotation of the rotation shaft 40 is the wheel shaft 7. This is because the rotation of the wheel shaft (7) can act as a hindering element rather than further increasing the rotational force.

For the same reason as described above, when the auxiliary rotating power is transmitted to the wheel shaft 7 by the aforementioned electric unit 80 at the time of starting or accelerating the vehicle, the rotation speed of the output shaft (not shown) of the electric unit 80 is It is preferred to be larger than the rotational speed of the wheel shaft 7.

The shaft fixing unit 90 is installed on the above-described rotating shaft 40, and the shaft fixing unit 90 may not interlock with the wheel shaft 7 and the rotating shaft 40 according to a control signal received from the controller 70. In this case, the rotating shaft 40 is fixed so as not to rotate so that the accumulated elastic energy of the mainspring 50 is maintained as it is until the vehicle starts or accelerates. The rotating shaft 40 is controlled according to a control signal received from the controller 70. It may be configured in a form similar to the electric gripper for gripping or releasing the holding state on both sides of the outer peripheral surface.

The fifth sensor 100 is installed in the transmission 9 of the vehicle, and the fifth sensor 100 transmits a signal through the detection of the short shift of the transmission 9 to the controller 70, thereby providing a controller 70. Allows the vehicle to recognize whether the vehicle is braked or decelerated by combining with the signal of the first sensor 10 to store the power of the wheel shaft 7 as the elastic energy of the spring 50, or the second sensor 20. By detecting the start or acceleration of the vehicle through a combination of the signal of) to the elastic energy of the mainspring 50 is transmitted to the wheel shaft (7) as an auxiliary energy, detecting the short shift position of the transmission (9) It can be formed as a position sensor.

The signal transmitted from the fifth sensor 100 to the controller 70 is shifted to the high speed stage after the vehicle is started and all the elastic energy of the mainspring 50 is transmitted to the auxiliary rotational force of the wheel shaft 7. When the vehicle is driven by acting as one of the parameters for generating a control signal which causes the electric unit 80 to separate the wheel shaft 7 and the rotation shaft 40 together with the signal of the fourth sensor 60 when it is made. B accelerates the rotational shaft 40 by the rotation of the wheel shaft (7) during acceleration to prevent the spring 50 from being broken.

The operation switch 110 is installed in the vehicle's interior. The operation switch 110 transmits a signal to the controller 70 according to pressure to play a role of controlling the operation of the electric unit 80. Through this can be turned on (on) or off (off) the operation of the vehicle energy efficiency increasing device (1) using the mainspring according to the present invention. In the off state of the operation switch 110, the rotary shaft 40 and the wheel shaft 7 are released from interlocking after the elastic energy of the spring 50 is accumulated or the elastic energy is reduced to the wheel shaft 7. To keep the state constant.

The driver may turn off the operation of the vehicle energy efficiency increasing apparatus 1 using the mainspring according to the present invention when driving downhill or driving slowly through the operation of the operation switch 110. This gives the driver more choice.

Hereinafter, referring to the accompanying drawings, the energy efficiency increasing apparatus 1 for a vehicle using the mainspring according to the present invention will be described as follows.

First, when the controller 70 detects that the current vehicle is gradually being lowered for stopping by input of signals from the first sensor 10, the third sensor 30, and the fifth sensor 100, the electric unit ( As the control signal is transmitted to the 80 and the shaft fixing unit 90, the transmission unit 80 can be rotated in the direction in which the rotating shaft 40 is wound in the spring 50 with respect to the rotation direction of the wheel shaft (7). The interlocking and the shaft fixing unit 90 releases the gripping state so that the rotating shaft 40 can be rotated. As a result, the spring 50 on the rotating shaft 40 is wound while the rotating shaft 40 is rotated. Energy is accumulated in the form of elastic energy of the mainspring 50.

When the controller 70 detects that the elastic energy of the mainspring 50 has been accumulated by the signal of the fourth sensor 60, the control signal is transmitted to the electric unit 80 and the shaft fixing unit 90. As such, the electric unit 80 releases the interlocking state between the wheel shaft 7 and the rotating shaft 40 and the shaft fixing unit 90 protects the mainspring 50 by holding the rotating shaft 40 so that it cannot be rotated. .

When the controller 70 detects that the vehicle is stopped by the input of the signals of the first sensor 10, the third sensor 30, and the fifth sensor 100, the electric unit 80 and the shaft fixing unit 90. In accordance with the transmission of the control signal to the transmission unit 80 releases the interlocking state of the wheel shaft 7 and the rotary shaft 40, and the shaft fixing unit 90 gripping the rotating shaft 40 so that it can not be rotated The elastic energy of 50) is maintained until the vehicle starts or accelerates.

When the controller 70 detects that the vehicle is currently starting or accelerates at a low speed stage by input of signals from the second sensor 20, the third sensor 30, and the fifth sensor 100, By transmitting a control signal to the motor unit 80 and the shaft fixing unit 90, the motor unit 80 is interlocked so that the rotation shaft 40 can be rotated in a different direction with respect to the rotation direction of the wheel shaft (7), The shaft fixing unit 90 releases the gripping state so that the rotating shaft 40 can be rotated, and as a result, the rotating shaft 40 is reversed while the spring 50 is released by the elastic energy accumulated in the spring 50. The reverse rotational power is rotated again by the electric unit 80 in the forward direction so that the auxiliary rotational power can be provided to the wheel shaft 7.

When the controller 70 senses exhaustion of the elastic energy accumulated in the spring 50 by the signal of the fourth sensor 60, the controller 70 transmits a control signal to the electric unit 80 and the shaft fixing unit 90. The transmission unit 80 releases the interlocking state of the wheel shaft 7 and the rotary shaft 40, the shaft fixing unit 90 is to hold the rotary shaft 40 again so that the rotary shaft 40 can not be rotated, As a result, the rotary shaft 40 and the mainspring 50 do not operate at all during the constant speed driving except for stopping and starting the vehicle. The signal of the fourth sensor 60 serves as a main parameter for controlling the provision of the auxiliary rotational power at the start and stop of the vehicle.

When the controller 70 detects that the current vehicle is gradually being lowered for stopping by the input of signals from the first sensor 10, the third sensor 30, and the fifth sensor 100 while the vehicle is driving, The operation will be repeated again.
