Description

Technical Field

[0001] This invention belongs to the field of mechanical power, and specifically relates to a drive-by-wire flywheel transmission device. Background Technology

[0002] A flywheel (hereinafter referred to as a flywheel) is a classic mechanical device, but it is rarely used in daily life. This is because, firstly, its reciprocating rotation requires changing the direction of rotation; and secondly, it requires a flexible cable, as direct application would not provide sufficient power. Therefore, its application is not widespread in practice. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned technical defects and provide a flywheel mechanical device that can be widely used in production, daily life and other fields.

[0004] The technical solution of the present invention: This invention consists of two main parts: a flywheel transmission device and its specific application. The flywheel transmission device comprises four parts: a flywheel, a driven wheel, a lever structure, and a transmission.

[0005] A flywheel is a type of wire-controlled flywheel characterized by having one or more pawls installed on each side of its outer edge, with the pawls on both sides facing opposite directions; the flywheel surface has two or more cable holes, with bearings or other anti-wear devices inside the holes; the cable is treated for wear resistance and coated with lubricating oil.

[0006] Alternatively, the flywheel body can be a rotating component of various shapes other than circular (collectively referred to as a flywheel in this document and other documents of this application); Optionally, there are fixing buckles integrated with the wheel surface on both sides. The buckles may contain rotating balls, and the pull cables on both sides are directly fixed to the buckles without having to pass through the cable holes. Optionally, a shaft passes through the bearing inside the bore, with pull wires connected to both ends of the shaft; Optionally, a slide-type groove can be installed on the flywheel surface to adjust the point of action between the cable and the flywheel, thereby changing the force exerted by the cable on the flywheel. Optionally, the outer edge of the flywheel can be replaced with a ratchet instead of a pawl, with the ratchets on both sides facing opposite directions; Optionally, the flywheel has a bevel gear on its outer edge, the bevel gear face being a ratchet or a pawl, which meshes with the pawl or ratchet on the outer edge of the flywheel, respectively; Optionally, the two ends of the flywheel cable are connected to the ends of the lever resistance arms.

[0007] Driven wheels (coaxial double-wheel device) – from the outer ring to the inner ring, consist of a gear, a ratchet, a bearing, a fixed tube, and a bracket. The bearing is fitted onto the outside of the fixed tube. The outer gear and the inner ratchet are integrated and fitted onto the bearing, rotating synchronously. There are two identical sets of driven wheels, symmetrically installed on both sides of the fixed tube, meaning the ratchet directions on both sides are opposite. A bevel gear (or planar gear, hereinafter referred to as bevel gear in other documents of this application) is located on the outer edge of each driven wheel. The bevel gear meshes with the gears on the outer edges of the two driven wheels on both sides, and the bevel gear is connected to the power output shaft.

[0008] Optionally, a pawl can be used instead of a ratchet on the inside of the driven wheel; Optionally, the connection between the driven wheel and the fixed tube is not limited to bearings; magnetic levitation, sliding shafts, and other methods can be used. The flywheel drive system consists of a flywheel and driven wheel, combined with a lever and a gearbox. The outer ring of the flywheel, with a bearing, is fitted inside the fixed tube wall. Pads on both sides of the flywheel engage with ratchet wheels on both sides of the driven wheel. When the flywheel rotates in one direction, one pawl drives a set of driven wheel ratchet wheels and an outer gear to rotate. The outer gear drives a bevel gear that meshes with it to rotate, and the bevel gear's rotation drives the gear meshing with it on another set of driven wheels to rotate. The same logic applies when the flywheel rotates in the opposite direction. This allows the bevel gears to rotate in the same direction, and power can be output through the connected power output shaft. The outer end of the cable is connected to one end of the lever resistance arm, and power is input to the power arm to drive the entire device. The power output shaft connected to the bevel gears is directly connected to the gearbox, which in turn connects to the function output shaft. Optionally, the outer ring of the flywheel is a ratchet wheel without pawls, and the ratchet wheel inside the driven wheel is replaced with a pawl, i.e., an outer pawl and inner ratchet structure. Alternatively, in addition to the above combination of flywheel and driven wheel, the outer edge of the flywheel can be replaced with a gear, and transmission can be achieved by meshing multiple sets of gears; The beneficial effects of this invention are as follows: This device mainly consists of a flywheel, a driven wheel, a lever, and a gearbox. It has a simple structure and is easy to install. The flywheel automatically springs back after being wound, providing additional power and achieving high rotational speed. The driven wheel converts the rotation from opposite directions to the same direction, enabling practical applications. The flywheel pulling distance is not very long and is relatively fixed, and the lever saves a significant amount of power. Furthermore, the gearbox enables starting and gradual acceleration, achieving even higher rotational speeds. Therefore, this device is simple to use, energy-efficient, and high-speed, making it widely applicable.

Functional output shaft; Detailed Implementation The embodiments described below with reference to the accompanying drawings include: (1) the structure and specific operation of the flywheel device, component description, and combination of multiple devices; (2) the power generation device; (3) the underwater vehicle; (4) the aircraft; (5) the vehicle; and (6) the machinery and equipment tools.

[0010] Example (1): Structure and specific operation of the flywheel device: Structure, such as Figures 1 to 3 Bearing 6 is fitted onto the outside of fixed tube 13, bearing 7 is fitted onto the outside of fixed tube 14, bearing 16 is located at fixed tube 12, flywheel 1 is installed inside bearing 16, pawls 2 and 3 on both sides engage with ratchet wheels 8 and 10 on both sides respectively, and pull cable 4 is connected to lever end 5 at both ends. Fixed tube is secured by fixed rod 15 and similar device.

[0011] First, tighten the pull line 4 and then release it. The flywheel 1 begins to rotate, applying force to levers 33 and 34. Pulling the pull line 4 through lever end 5 causes the flywheel 1 to rotate continuously. When the flywheel 1 rotates clockwise, the pawl 2 on side A drives the ratchet 8 and the outer gear 9 to rotate clockwise. At this time, the bevel gear 203 is also driven by gear 9, causing its side gear tooth 17 to rotate clockwise. Simultaneously, while the flywheel rotates clockwise, the pawl 3 on side B does not engage with the ratchet 10 on side B, but slides past it. However, the gear 11 of the driven wheel B on the flywheel's side is driven by the clockwise rotating bevel gear 203's side gear tooth 9, causing it to rotate counterclockwise. Conversely, when the flywheel 1 rotates counterclockwise, the pawl 3 on side B engages with the ratchet tooth 10, driving gear 11 to rotate counterclockwise. This, through gear 18, keeps the bevel gear 203 rotating clockwise, and also drives gear 9 to rotate clockwise. In other words, one side always drives the bevel gear 203 to rotate in the same direction, while the other side is also driven, maintaining the same speed and inertia, which is beneficial for the rotation of flywheel 1. A connecting shaft 20 at bevel gear 19 is connected to the transmission gear 21. When the bevel gear rotates, the transmission gear 21 rotates accordingly, driving the function output shaft 22 to rotate. By operating the transmission, the speed can be adjusted according to actual needs, thereby achieving low-speed start-up and acceleration.

[0012] Transmission: such as Figure 4 As shown, when flywheel 1 starts, the transmission gears and shifter are in the initial gear position. When upshifting, grip the upshift handle 25, tighten the spring 24, causing the spring to retract. The gear shift wheel 23 can move along the sliding square shaft 29. Simultaneously, move the upshift handle 25 away from the slot 27, push the upshift handle 25, pull the cable, and make the gear shift wheel 23 move up to the appropriate gear in the engaged state. Then put the handle 25 back into the corresponding marked slot 27, and the spring pops out and locks, completing the upshift. To downshift, use the downshift handle 26 and operate in the reverse direction.

[0013] The aforementioned transmission can be equipped with a clutch, such as... Figure 5 Everything else remains the same, except that the gear shift wheel 23 can be raised via the sliding square shaft 29, moved to the appropriate gear, and then lowered. This allows the clutch to be released before the flywheel starts, and then released after reaching a certain speed to drive the functional shaft. This reduces the size of the transmission gears and allows for improvements to the transmission gear 28, making it movable and enabling more gear shifts.

[0014] The aforementioned transmission and clutch can be integrated into a single control lever, as shown in the following manner. Figure 9 They share a single control panel, with independent levers. The original transmission cable is wound around a rotatable disc with a slot. There is a fixed graduated dial on the left side, and the clutch also has a slot. When the lever is moved to the clutch slot, the clutch is engaged; after disengaging, it is moved back to the transmission slot to engage the transmission.

[0015] In addition to the devices mentioned above, various existing mechanisms can be used to achieve gear shifting. For example, common bicycle freewheel derailleurs and chain drives can be used; the only difference is that the components need to be installed in the appropriate positions according to the specific circumstances.

[0016] Lever application method: Depending on the application scenario, levers can be applied in various ways, including manual methods such as direct push-pull, foot pedal, and foot-operated wheel levers; and powered methods such as wheel levers. (See attached image.) Figure 7 As shown in figure a, the foot pedal type has a spring under the foot pedal 30, which is connected to levers 33 and 34 through steel cable 31 and fixed pulley 32. When the foot pedal 30 is pressed down, it is released, thereby pulling and releasing levers 33 and 34.

[0017] For example Figure 7 In the foot-operated wheel type b, the foot pedal causes the wheel 35 to rotate, and the fixed rod 36 on the wheel moves back and forth alternately, driving the steel cable to pull and release the lever.

[0018] For power-driven applications, the outer ring of the aforementioned pedal wheel 35 can be directly fitted with a gear, and the power output end can mesh with this gear. Examples include the power end of an electric motor, the outer end of an engine crankshaft, and the output end of natural forces (water power, wind power, tides, ocean waves, etc.).

[0019] The above connection methods using steel cables and fixed pulleys are just examples. In practice, various methods such as connecting rods and sliders can be used to improve the effect.

[0020] Launcher: like Figure 8 As shown, a circular groove is added to the outside of the driven wheel, integrated with the driven wheel. A spring coil 37 is wound around the groove and connected to a hand-cranked turntable 38 via a steel cable. Normally, the spring coil 37 is in the open state and does not contact the groove. When starting, cranking the hand crank pulls the steel cable, tightening the spring 37 and causing the wheel sleeve to rotate, thereby turning the flywheel cable. After tightening, it is released, and the spring 37 automatically springs out, disengaging from the circular groove and returning to the open state. Releasing it simultaneously drives the lever, causing the flywheel to rotate.

[0021] Multiple sets of drive-by-wire flywheel devices: The above describes the single flywheel operating mechanism. To address the issue of insufficient rotational power relying solely on the cable's rebound force after tightening, an additional flywheel and driven wheel can be added. The two sets of devices are tightened and released alternately, ensuring a constant external force acts on the bevel gears. The flywheels can be positioned left-right or up-down. Each set has a bevel gear, but they are no longer connected to the power output shaft 20. Instead, they mesh with a newly added bevel gear connected to the power output shaft 20, ensuring that this new bevel gear rotates in the same direction. The lever can be used to apply force in a one-to-one manner or simultaneously tighten and loosen.

[0022] Applying force one-on-one, such as Figure 9c. Two sets of flywheel assemblies are distributed on the left and right sides, with levers on both sides corresponding to their respective flywheel assemblies. Several fixed pulleys are installed at appropriate positions inside the flywheel assemblies to connect to the inner pull lines (e.g., ...). Figure 9 d) This is used to change the direction of force applied to the inner pull rope. When the lever on this side is pulled back, the pull ropes on both sides of the flywheel are pulled outwards simultaneously. When the lever is pushed outwards, the pull ropes on both sides are released simultaneously. The same applies to the other side. The two sides are pushed and pulled alternately to maintain power output. For the lever's force application end, such as a foot pedal, the two foot pedals rise and fall alternately; for a wheel, an additional fixed rod is added, located on the other side of the wheel, at both ends of a diameter, which is alternately extended and retracted when the wheel rotates.

[0023] When the lever is extended and retracted simultaneously, and the two flywheel devices are distributed vertically, as follows: Figure 9 As shown in diagram a, one set of flywheel devices applies force using leverage, just like a single flywheel; as... Figure 9 b. By using two fixed pulleys installed on the outside of the lever's resistance end to change the direction of force of the other flywheel device, the flywheel is pulled when the lever is released. This maintains the synchronous movement of the two levers and allows the two flywheel devices to alternately extend and retract, maintaining both power output and rebound force output.

[0024] When starting, one flywheel is tightened by the starter and springs back when released, causing the bevel gear and driven wheel to tighten the other flywheel, thus achieving alternation.

[0025] To achieve alternating force application from the two flywheel devices, one method is to adjust the operation according to the actual situation; another method is to add a clutch between the newly added common bevel gear and one of the flywheel devices. First, one set of flywheels drives the common bevel gear. After the two sets of flywheel devices achieve alternating force application, the clutch is released to achieve joint driving of the common bevel gear.

[0026] Depending on the specific circumstances, two or more of the above-mentioned flywheel devices may be installed. The operating principle is generally the same, but modifications are required.

[0027] The power and elasticity can also be changed by altering the size and material of the flywheel.

[0028] The following embodiments all use the above-described device (without accompanying drawings), and the principle is relatively simple. They are described below:

[0029] Example (2) describes a power generation device equipped with the device described in Example (1). The functional output shaft is connected to the generator rotor, driving the rotor to rotate. For the power input end, manual operation can utilize levers, foot pedals, foot-operated wheels, etc., while power-driven operation can utilize gears to drive the wheel, etc. Specifically, it can be a manual generator such as an outdoor manual generator, fitness power generation facility, or emergency manual power generation facility; a fuel generator such as a diesel generator or thermal power generator; or a natural power generator such as a hydroelectric, wind, or tidal generator.

[0030] Since ocean waves and tides rise and fall and move back and forth, the flywheel in the dual-wheel device of this invention can be removed and replaced with a set of blades (fan blades) so that they rotate in both directions in the direction of the water flow. The rotation is achieved in the same direction through the bevel gear at the rear, thereby driving the generator rotor to generate electricity.

[0031] Example (3) describes a surface or underwater vehicle equipped with the flywheel device described in Example (1). A marine propeller is mounted on the functional output shaft; for surface vehicles, it could be an aircraft propeller, a turbofan, or other wind-powered propulsion device. Power sources can include human power, electricity, or fuel. Specifically, it can be surface vessels such as small civilian boats, recreational boats, speedboats, or unmanned vehicles; or underwater vehicles such as manned or unmanned submersibles or submarines.

[0032] Example (4): An aircraft equipped with the flywheel device described in Example (1), with an aircraft propeller mounted on the functional output shaft.

[0033] Specifically, it can be: a delta wing aircraft: an unpowered delta wing, where a person takes off with a running start and then activates the device to provide flight power; a powered delta wing, where the original power facility can be removed, the propeller can be retained, and a flywheel device can be installed, which can be activated on the ground to replace the original power setting and achieve flight by human power; or the original power facility can be retained and used alternately as needed to increase the range and reduce fatigue.

[0034] It can be used as a power unit for aircraft such as gyroplanes, propeller planes, helicopters, airships, paragliders, drones, and low-altitude bicycles. The principle is the same as that of the hang gliders mentioned above, and it can be powered by human or artificial power as needed.

[0035] Using a flywheel as the power source for an ornithopter has its advantages, such as doubling the power and enabling reciprocating motion. The possibility of realizing this in the future can be explored.

[0036] Example (5): A vehicle equipped with the flywheel device described in Example (1), wherein the functional output shaft is equipped with a wind-driven device such as an aircraft propeller, or is directly connected to the wheel mechanism via gears, chains, belts, etc.

[0037] Specifically, this could be for bicycles: propeller-type wind-powered bicycles driven by a lever connected to a sprocket; or wheel-driven bicycles with a gear rotating in the same direction as the wheel added to the output end, using a bevel gear for direction changing, and a flywheel added to the left side of the rear axle, connected to the new gear via a chain. The original bicycle mechanism remains largely unchanged, with the original pedal sprockets being modified. Figure 7 As shown in Figure c, the fixed rod has a latch at the connection point between it and the lever's power arm. The latch closes at a certain speed, activating the flywheel mechanism via a starter to provide power assist and acceleration. This can be used on two-wheeled, three-wheeled, or four-wheeled bicycles.

[0038] Electric vehicles, fuel vehicles, and other vehicles differ from the bicycles mentioned above in that their power output ports, such as the motor output shaft and the engine crankshaft output end, are connected to a flywheel device to start the wheel, which is driven by gear meshing.

[0039] In Example (6), various machines, equipment, tools and utensils, after proper installation, can be used in production and daily life. There are many devices that can use the flywheel device of this invention. Large production equipment that are suitable for connecting this device with an electric motor or engine can be used for energy saving. Small facilities and tools such as grinders, lawnmowers, bench drills, washing machines and many other facilities, including those driven by human power.
