Problems to be solved by the invention

[0004] Although the hybrid vehicle of Patent Document 1 has a hybrid structure of an engine and a motor / generator, all of them are driven by a power source in which fossil fuel is burned.

In the present invention, attention has been paid to the use of clean gravity (attraction) among the natural energy working on the earth. Examples of gravity usage include charging a vehicle-mounted battery using hydroelectric power generation using elevation differences and an engine brake on downhill. However, if the height difference disappears or the downhill route is finished, the gravity can no longer be used, and there is a limit to the continuous use of the height difference and the downhill route.

[0005] In this regard, when focusing on a four-wheeled vehicle, the total weight of about 1000 kg is shared by four wheels. Running. For this reason, at a ground contact position where a predetermined part of the wheel is in pressure contact with the traveling surface, the tire is compressed and deformed due to the total weight, and at a non-contact position where the predetermined part of the wheel is away from the traveling surface, the tire is released from the total weight force. Restores its original shape. The vertical movement of the wheel caused by this has been released to the outside as vibration energy without being used.

[0006] The present invention has been made in view of the above circumstances, and can be utilized for auxiliary power, charging of an in-vehicle battery, and the like by effectively using the vertical fluctuation of the wheel generated during traveling as a power source. The object is to provide a vehicle wheel engine.

Means for solving the problem

[0007] (About claim 1)

A vehicle wheel engine includes a crank that is provided with a rotatable crank shaft at the center of a tire wheel of a wheel. The first connecting rod is connected to the crank in the tire wheel. The support shaft is stretched between the left and right side walls of the tire wheel so as to be parallel to the crankshaft. The second connecting rod is rotatably provided on the support shaft, one end is rotatably connected to the first connecting rod, and the other end is directed to the inner peripheral surface of the tire. A portion of the shoe is pivotally connected to the other end of the second connecting rod so that it can slide on the inner peripheral surface of the tire. As the wheel fluctuates up and down during running, the part of the wheel that contacts the running surface compresses and deforms, and a portion of the shoe is pressed against the inner circumferential surface of the tire, causing the second conduit to rotate around the support shaft. The moment is received and transmitted to the first connecting rod to rotate the crank and use it as a power source.

[0008] Since a part of the shoe receives a pressing force from the inner peripheral surface of the tire due to the vertical fluctuation of the wheel, the second connecting rod functions as an insulator having the support shaft as a fulcrum. In this case, considering the total weight of the vehicle, it can be seen that a large rotational moment is generated in the second connecting rod. Because of this large rotational moment, the crank is rotated via the first connecting rod, so that a large power source can be obtained and used effectively for auxiliary power for vehicles and charging of in-vehicle batteries. Since the vertical movement of the wheel is generally released to the outside as vibration energy, the power source is generated without supplying any new energy. As a result, it is also suitable for environmental conservation and energy saving measures.

[0009] (About claim 2) The second connecting rod is made up of a short arm portion and a long arm portion that extend in a square shape at a predetermined angle from the branch portion. For this reason, the rotation angle ratio between the short arm portion and the long arm portion can be determined as desired by setting the length dimension ratio between the short arm portion and the long arm portion to a predetermined value.

[0010] (About claim 3)

The first connecting rod and the second connecting rod are arranged adjacent to each other as a pair of upper and lower pairs. For this reason, every time the wheel makes one revolution, the power source can be generated continuously at two locations on the tire, and the power source can be doubled to make the rotation smooth and stable.

[0011] (About claim 4)

The first connecting rod and the second connecting rod are arranged adjacent to each other at predetermined angular intervals in two pairs on the left and right as a pair of upper and lower yarns. For this reason, every time the tire makes one revolution, the power source can be continuously generated at four locations of the tire, and the power source can be quadruple to make the rotation smooth and more stable.

[0012] (About claim 5)

A portion of the shoe has a pair of upper and lower leaf springs whose opposing end portions are coupled to each other, and a compression coil spring provided between the leaf springs. For this reason, when a part of the shoe is also subjected to the pressing force of the inner peripheral surface of the tire, the compression coil spring moves the leaf spring up and down while expanding and contracting, absorbing the pressing force and applying an impact to the second connecting rod. ease. As a result, the second connecting rod can smoothly transmit the rotational moment to the first connecting rod, and these members can be prevented from being damaged or damaged, thereby contributing to improvement in durability.

[0013] (About claim 6)

A portion of the shoe is a rubber body having a hard rubber piece that is in sliding contact with the inner peripheral surface of the tire at the tip. For this reason, when a portion of the shoe receives the pressure of the inner circumferential surface of the tire, the rubber portion of the portion of the shoe is elastically deformed to reduce the impact on the second connecting rod, and the same effect as in claim 4 is achieved.

[0014] (About claim 7)

In the periphery of the spindle of the second connecting rod, there is a return control section that extends to the opposite side of the shoe part by centrifugal force. The return control unit has a cylinder part and a piston part slidably provided in the cylinder part, and the piston part is oriented in the direction of the support shaft by a tension coil spring. Is being energized.

In this case, as the vehicle speed increases, the wheel rotates faster and a large centrifugal force acts on the second connecting rod. The piston part resists the urging force of the tension coil spring by centrifugal force.

, Sliding and extending in the opposite direction to the spindle. For this reason, the inertial force of the return control unit increases, the return rotation speed at which the second connecting rod returns toward the inner peripheral surface of the tire is reduced, and the impact of the first connecting rod on the inner peripheral surface of the tire is reduced. it can.

[0015] (About claim 8)

The crank is connected to a torque converter that facilitates rotation of the tire wheel. For this reason, the vertical fluctuation of the wheel can be added to the rotation of the tire wheel and used as auxiliary power for the wheel.

[0016] (About claim 9)

The crank is connected to a generator that charges the in-vehicle battery. For this reason, the vertical movement of the wheel functions as auxiliary power for the generator that charges the in-vehicle battery.

The invention's effect

In the vehicle wheel engine of the present invention, due to vertical fluctuation of the wheel, a part of the shoe receives a pressing force of the inner peripheral surface force of the tire, and the second connecting rod functions as an insulator with the support shaft as a fulcrum. Due to the total weight of the vehicle, a large rotational moment is generated in the second connecting rod. As a result, a large power source can be obtained by rotating the crank via the first connecting rod, which can be fully utilized for auxiliary power for vehicles and charging of on-vehicle batteries.

BEST MODE FOR CARRYING OUT THE INVENTION

[0020] Due to the vertical movement of the wheel that occurs when the vehicle is running, a part of the shoe receives the pressing force of the inner peripheral surface force of the tire, and the second connecting rod acts as an insulator with the support shaft as a fulcrum. A large rotational moment is generated in the second connecting rod, and the crank is rotated to secure a power source with sufficient output as auxiliary power.

Example 1

Example 1 of the present invention will be described with reference to FIGS. 1 and 2.

In a wheel 1 provided in a vehicle (not shown), left and right side walls 2a and 2b are attached to a tire wheel 2 as shown in FIG. A crank 3 is rotatably supported in the tire wheel 2 via a crankshaft 3a at the center of the side wall 2a. A crank 4 is rotatably supported in the tire wheel 2 via a crankshaft 4a at the center of the side wall 2b. An intermediate crank 5 is disposed between the cranks 3 and 4.

A first connecting rod 7 is provided between the crank 3 and the intermediate crank 5, and one end of the first connecting rod 7 is rotatably connected to the crank 3 and the intermediate crank 5 via a pin 6. Between the side walls 2a and 2b, support shafts 8 and 9 that are opposed in the radial direction are stretched in parallel with the crankshafts 3a and 4a. The support shaft 8 is attached so as to be rotatable around the second connecting rod 10-shaped force branching portion 10a having a U-shape. The second connecting rod 10 is composed of a short arm portion 10b and a long arm portion 10c extending in a dogleg shape at a predetermined angle from the branch portion 10a. The length dimension ratio between the short arm portion 10b and the long arm portion 10c is set to a predetermined value in consideration of the diameter size of the tire 14, the diameter size of the crank 3, and the like.

[0023] The long arm portion 10c of the second connecting rod 10 is rotatably connected to the first connecting rod 7 via a pin 11, and the short arm portion 10b is rotatable to a short leg portion 13 via a pin 12. It is connected to. At the tip of the short leg 13, a shoe part 15 that is in sliding contact with the inner peripheral surface of the tire 14 is attached. Another first connecting rod 16 is provided between the crank 4 and the intermediate crank 5, and one end thereof is rotatably connected to the crank 4 and the intermediate crank 5 via a pin 17. A second U-shaped connecting rod 18 is attached to the support shaft 9 so as to be rotatable about a branching portion 18a. The second connecting rod 18 is composed of a short arm portion 18b and a long arm portion 18c extending from the branching portion 10a in a dogleg shape at a predetermined angle. The length dimension ratio between the short arm portion 18b and the long arm portion 18c is set to the same value as that of the second connecting rod 10 in consideration of the diameter size of the tire 14 and the diameter size of the crank 4. .

[0025] The long arm portion 18c of the second connecting rod 18 is rotatably connected to the first connecting rod 16 via the pin 19, and the short arm portion 18b is rotatable to the short leg portion 21 via the pin 20. It is connected to. A shoe portion 22 that is in sliding contact with the inner peripheral surface of the tire 14 is attached to the distal end portion of the short leg portion 21. In this state, the first connecting rods 7 and 16, the second connecting rods 10 and 18, and the cranks 3 and 4 are arranged adjacent to each other on the left and right, and these constitute the wheel engine 1A as a whole. That is, in the wheel engine 1A, the first connecting rod 16 (7) and the second connecting rod 18 (10) are adjacently arranged in a pair on the left and right as an upper and lower combination pair.

[0026] In the above configuration, when the vehicle travels in the direction indicated by the arrow M in Fig. 2, the wheel 1 rotates in the direction of the arrow N. As a result, the vehicle receives a vertical fluctuation force on the running surface 23, so that the tire 14 of the wheel 1 receives the total weight of the vehicle and elastically deforms at a contact position where a predetermined portion of the tire 14 is in pressure contact with the running surface 23. To hold in the compression direction. As the tire 14 is compressed and deformed, the shoe portion 22 receives a pressing force from the inner peripheral surface 14a of the tire 14, and the second connecting rod 18 is centered on the support shaft 9 via the short leg portion 21 and the pin 20. (See arrow A in Fig. 2).

Due to this rotational moment, the second connecting rod 18 acts as a lever and rotates in the direction opposite to the clockwise direction, and the first connecting rod 16 is rotated in the direction of arrow B via the pin 19. By rotating the first connecting rod 16, an external force in the direction of arrow C is generated on the pin 17. With this external force, the crank 3 is rotated together with the intermediate crank 5 and the crank 4 by an angle of 180 degrees in the direction of arrow D while allowing the first connecting rod 7 to be freely rotated and displaced.

This rotational movement is achieved when the second connecting rod 18 and the wheel 1 are at 90 degrees from the position P force to the position Q. Occurs when rotated by an angle of. For this reason, every time wheel 1 rotates 90 degrees, crank 4 together with intermediate crank 5 and crank 3 will rotate 180 degrees, which is twice that of wheel 1.

In this case, the compression displacement δ of the tire 14 with respect to the running surface 23 is known in advance, and the link length dimension ratio between the second connecting rod 18 (including the short arm portion 18b and the long arm portion 18c) and the first connecting rod 16 is determined. Decide. The compression displacement δ of the tire 14 transmitted to the second connecting rod 18 is set so that the crank 3 can be rotated by a half circumference (approximately 2 XR in terms of radial distance) via the first connecting rod 16. .

[0028] When the predetermined portion of the tire 14 is rotated from the ground contact position to the non-ground position away from the running surface 23, the second connecting rod 18 receives the centrifugal force of the wheel 1 and rotates in the direction opposite to the arrow Α. Return to the original position. Along with this, the first connecting rod 16 freely rotates in the direction opposite to the arrow B around the pin 17 that does not affect the rotation of the crank 3.

[0029] Also for the second connecting rod 10, when the non-grounding position force of the specific part of the tire 14 away from the running surface 23 also rotates to the grounding position, the second connecting rod 10, the first connecting rod 16, the short leg 21 and the shoe The part 22 operates in the same way as the second connecting rod 18.

Therefore, the rotation of the first connecting rod 7 that receives the rotational moment of the second connecting rod 10 generates an external force on the pin 6 and rotates the crank 4 together with the intermediate crank 5 and the crank 3 by an angle of 180 degrees. . Each time wheel 1 rotates 90 degrees, crank 4 together with intermediate crank 5 and crank 3 will produce a 180 degree rotation that is twice that of wheel 1.

[0030] Incidentally, it is assumed that a passenger car has a 13-inch wheel, the total weight of the vehicle is about 1000 kg, and an eccentric distance R between the crankshaft 3a (4a) and the pin 6 (16). When the vehicle wheel engine 1A is installed on four wheels, if a load of approximately 250 kg is applied to each wheel 1, the rotational torque T of the crank 3 (4) is It seems to be. Unbalanced, distance R force S 15cm, rotation Tonlek T = 250kg X 0.15m X 9. 8 X 2

= 735Ν · πι.

Even if eccentric distance R is 10cm, rotational torque T = 250kg X O. 10mX 9.8 X 2

= 490Ν · πι.

[0031] For example, when a vehicle with 13-inch wheels travels at a rate of 2 seconds at 16 m, the wheel will rotate 5 times. Roll. The crankshaft 3a (4a) rotates 10 times each together with the crank 3 (4), making a total of 20 rotations.

In this case, crank 3 (4) is 10 revolutions per second, so for a crank with an eccentric distance R of 15 cm, the work per second (U) is 735 N'm X 10 (lZs) = 7350 N'm ' (l / s) = 7.4 4kW.

Even with an eccentric distance R of 10cm, the work per second (U) is 490N'mX 10 (1 Zs) = 4900N-m- (1 / s) = 5. OkW.

Example 2

FIG. 3 shows a second embodiment of the present invention. In the second embodiment, a cap-shaped rubber cover 24 that secures airtightness between the tire 14 and the tire wheel 2 is provided near the support shaft 9 (8). The rubber cover 24 has a central portion 24a passing through the second connecting rod 18 (10) and an opening peripheral portion 24b fixed to the tire wheel 2. The central portion 24a is hermetically bonded to the second connecting rod 18 (10) by an adhesive 25. The opening peripheral portion 24b of the rubber cover 24 is hermetically bonded to the tire wheel 2 by the same adhesive 25.

[0033] For this reason, even if the second connecting rod 18 (10) force is protruded into the tire 14 at the periphery of the support shaft 9 (8), the second connecting rod 18 against the tire wheel 2 has a rubber cover 24 force. Seal the insertion part of (10) in an airtight manner.

When the second connecting rod 18 (10) receives a rotational moment, as shown in the first embodiment, the shoe portion 15 (22) receives a pressing force from the inner peripheral surface 14a of the tire 14, and the second connecting rod 18 (10 ) Rotates around the pivot 9 (8). When the second connecting rod 18 (10) is released from the pressing force, the second connecting rod 18 (10) is rotated back by centrifugal force.

At this time, the rubber cover 24 is elastically deformed according to the rotational displacement of the second connecting rod 18 (10), so that the airtightness in the tire 14 is maintained without loss.

Example 3

FIG. 4 shows a third embodiment of the present invention. In the third embodiment, a return control unit 26 is provided around the support shaft 9 (8) of the second connecting rod 18 (10). The return control unit 26 extends to the opposite side of the shoe portion 22 (15). The return control unit 26 includes a cylinder portion 27 and a piston portion 28 that is slidable in the cylinder portion 27. Piston part 28 has a tension coil as shown by arrow S in FIG. The spring 29 is urged in the direction of the support shaft 9 (8).

In this case, as the speed of the vehicle increases, the rotation of the wheel 1 becomes faster and a large centrifugal force acts on the second connecting rod 18 (10). The piston part 28 resists the urging force of the tension coil spring 29 due to the centrifugal force, and slides in the opposite direction to the support shaft 9 (8) as shown by the two-dot chain line in FIG. It extends to.

As a result, the inertial force of the return control unit 26 increases, and the second connecting rod 18 (10) is centered on the support shaft 9 (8), and the inner peripheral surface 14a of the tire 14 is in the direction opposite to the arrow A in FIG. The return rotation speed to return to the direction is reduced. As a result, the impact of the second connecting rod 18 (10) on the inner peripheral surface 14a of the tire 14 can be reduced, and damage or breakage to these members can be prevented. Example 4

FIG. 5 (a) shows Example 4 of the present invention. In the fourth embodiment, the shoe part 30 includes a pair of upper and lower leaf springs 31 and 32 and a compression coil spring 33 provided between the leaf springs 31 and 32. The leaf springs 31 and 32 are opposed to each other at opposite ends corresponding to each other by spherical bodies 34 and 35.

[0037] For this reason, when the shoe portion 30 receives a pressing force from the inner peripheral surface 14a of the tire 14, the compression coil spring 33 fluctuates the leaf springs 31 and 32 up and down with the expansion and contraction, thereby absorbing the pressing force. To reduce the impact on the second connecting rod 18 (10). As a result, the second connecting rod 18 (10) can smoothly transmit the rotational moment to the first connecting rod 7 (16), which prevents damage and damage to these parts and contributes to improved durability.

Example 5

FIG. 5 (b) shows Example 5 of the present invention. In the fifth embodiment, the sh part 36 is a rubber body 38 having a hard rubber piece 37 slidably in contact with the inner peripheral surface 14a of the tire 14 at the tip. The rubber body 38 has a corner portion 38a bonded to the tip of the second connecting rod 18 (10) as a hinge with an adhesive or the like. For this reason, when the shoe portion 36 receives a pressing force from the inner peripheral surface 14a of the tire 14, the rubber body 38 of the shoe portion 36 is elastically deformed to reduce the impact on the second connecting rod 18 (10). The same effect as Example 4 is achieved.

Example 6

FIG. 6 shows a sixth embodiment of the present invention. In Example 6, the crankshaft 3a of the crank 3 is a tire It is connected to a torque converter 39 that promotes the rotation of the wheel 2. The vertical movement of wheel 1 is added to the rotation of tire wheel 2 and used as auxiliary power for wheel 1.

In this case, in the torque converter 39, the casing 40 containing the fluid F therein is attached to the side wall 2a of the tire wheel 2 in a liquid-tight manner. The crankshaft 3a is connected to a drive shaft 42 in which a rotating blade 41 is fitted at the tip in the casing 40. A driving blade 43 facing the rotary blade 41 is fixed to the side wall 2a. On the side where the suspension 44 of the wheel 1 is located, the crankshaft 4 a is connected to a drive shaft 46 of the vehicle via a bearing 45.

[0041] As in the first embodiment, the rotational force of the crank 3 generated by the displacement of the second connecting rod 18 (10) and the first connecting rod 16 (7) is rotated via the crankshaft 3a and the drive shaft 42. Rotate blade 41 (see arrow J). The rotation of the rotary vane 41 is transmitted to the drive vane 43 via the fluid F and directly added to the wheel 1 via the side wall 2a (see arrow K). For this reason, the rotation of the wheel 1 is greatly promoted, and it is possible to realize a vehicle that is excellent in acceleration and power and capable of powerful driving.

Example 7

FIG. 7 shows Embodiment 7 of the present invention. In the seventh embodiment, the torque converter 39 of the sixth embodiment is omitted, and the crank 4 is connected to the generator 47. The up-and-down fluctuation of wheel 1 is used as auxiliary power for generator 47 to charge an in-vehicle battery (not shown).

In this case, as in Example 1, the rotational force of the crank 4 generated by the displacement of the second connecting rod 18 (10) and the first connecting rod 16 (7) is the crankshaft 4a, the bearing 45, the drive The shaft 46 and the power transmission path 49 of the differential gear mechanism 48 are connected to the rotating shaft 47a of the generator 47.

As in the first embodiment, the rotational force of the crank 4 generated by the displacement of the second connecting rod 18 (10) and the first connecting rod 16 (7) is transmitted to the rotating shaft 47a via the power transmission path 49. Drives generator 47. For this reason, fuel consumption is reduced and fuel consumption performance is greatly improved compared to a normal system in which a generator is driven by an in-vehicle engine.

Example 8 FIG. 8 shows Embodiment 8 of the present invention. The difference between Example 8 and Example 1 is that the first connecting rod 16 (7), the second connecting rod 18 (10), the short leg 21 (13), and the short part 22 (15) One addition.

That is, between the cranks 3 and 4, three intermediate cranks 5 are provided in a parallel state on the left and right. A pair consisting of a first connecting rod 16, a second connecting rod 18, a short leg portion 21, and a shoe portion 22 is disposed between the adjacent left intermediate crank 5 and central intermediate crank 5. A pair consisting of a first connecting rod 7, a second connecting rod 10, a short leg portion 13 and a shoe portion 15 is arranged between the adjacent middle intermediate crank 5 and right intermediate crank 5.

[0046] For this reason, when the shoe portion 22 (15) receives a pressing force from the inner peripheral surface 14a of the tire 14, the two second connecting rods 18 (10) alternately receive the rotational moment to generate two. The first rod 16 (7) is rotated and the intermediate crank 5 is rotated together with the cranks 3 and 4. As a result, the rotation of the intermediate crank 5 and the cranks 3 and 4 becomes smooth and stable.

Example 9

FIG. 9 shows Embodiment 9 of the present invention. Example 9 differs from Example 8 in that the first connecting rod 16 (7), the second connecting rod 18 (10), the short leg 21 (13) and the shrunk part 22 (15) are combined with each other. They are arranged at equiangular intervals of approximately 90 degrees. In this state, four first connecting rods 16 (7) and two second connecting rods 18 (10) are arranged adjacent to each other on the left and right, and two second connecting rods 16 (7) are arranged in the radial direction. Opposite to. In other words, the first connecting rod 16 (7) and the second connecting rod 18 (10) are arranged adjacent to each other at a predetermined angular interval of 90 degrees in two pairs of left and right as an upper and lower combination pair.

[0048] For this reason, the shoe parts 22 (15) receive the pressing force alternately from the inner peripheral surface 14a of the tire 14, and the second connecting rods 18 (10) individually receive the first connecting rod 16 Transmit the rotation moment to (7) and drive cranks 3 and 4 to rotate. As a result, every time the tire 14 rotates, the power source can be continuously generated at the four locations of the tire 14, the power source has a large output of four times multiplication, and the rotation is smooth and more stable. Can be made.

[0049] (Modification)

(a) The cranks 3 and 4 and the intermediate crank 5 are usually disk-shaped in order to obtain smooth rotation, but they may be oval or bowl-shaped as long as they can perform the crank function. Yo Yes.

(b) The length dimension ratio between the short arm portion 10b (18b) and the long arm portion 10c (18c) in the second connecting rod 16 (7) can be changed as desired. The same applies to the length dimension ratio between the first connecting rod 16 (7) and the second connecting rod 18 (10) and the short leg 21 (13).
