Description

[0001] TORQUE MULTIPLIER FLYWHEEL

[0002] FIELD OF INVENTION

[0003] A flywheel is a completely passive element that only provides the system with additional inertia, allowing it to store kinetic energy. The flywheel of the present invention is an element that provides the system with additional inertia and multiplies the torque.

[0004] Some driving sources, for example, electric, hydraulic, and pneumatic motors, do not require a flywheel, but the use of the flywheel of the present invention is justified in any driving source or power, because it multiplies the torque it has generated, giving greater capacity in newtons / meter to the driving power in the work to be performed.

[0005] PREVIOUS TECHNOLOGY

[0006] Torque is considered a vector magnitude, we could define it as the moment of force or dynamic moment, that is, it is the measure of the force applied to an axis to rotate an object, this moment of force is measured in newtons / meter.

[0007] Publication MX2013012847A refers to a torque multiplier device, which is coupled to the shaft of a motor, the shaft having a rectangular piece installed in a perforation arranged in the middle portion thereof, having on the lateral portions of said rectangular piece two half wheels that form a complete wheel. The intermediate wheels are held by means of two pins fixed in two rectangular pieces installed on the parallel surfaces of the wheel, these two parallel pieces being installed through a perforation in the middle portion of the shaft, the two intermediate wheels generating centrifugal force due to their arrangement, which is applied, with lever characteristics, exerting pressure in the direction of rotation on the opposite end portions of the rectangular piece that is fixed to the shaft, thus obtaining an increase in torque.

[0008] Publication WO / 2006 / 001686 refers to a rectangular torque arrangement, with two four-armed cross-shaped pieces with 90° angles assembled in pairs, aligned, separated and in a parallel position with a perforation in the center, in which an arrow is fixed that will be the axis of rotation of the entire apparatus, in the 90° spaces, delimited by the four arms of the cross-shaped pieces, four rectangular pieces are fixed, which, when the entire apparatus rotates, produce centrifugal force, these rectangular pieces act as a lever, with a support point on the axis of rotation and applying the centrifugal force on the arms in pairs and in a parallel position of the cross-shaped pieces, in which the rectangular levers are fixed and in the same direction of rotation, resulting in an increase in torque.

[0009] Technical problems of the two mentioned inventions and the solution with the present invention:

[0010] • Technical problem: they rely on centrifugal force to generate a given torque, using elements with a given mass, requiring high revolutions. At low revolutions, the effect of centrifugal force is minimal. -Solution to the technical problem: the present invention is based on the law of the lever, using a force arm of a given length to multiply the torque at low or high revolutions.

[0011] • Technical problem, it consumes energy from the driving force during acceleration to propel the mass components, and during deceleration it generates greater inertia due to the mass during deceleration.

[0012] -Solution to the technical problem: the power arm does not consume energy during acceleration and does not generate greater inertia during deceleration because low-mass materials can be used in the manufacture of the components.

[0013] • Technical problem, torque generation depends on the mass of the components, the greater the mass, the greater the torque generation by centrifugal force, drastically increasing the mass of the driving power, increasing the weight-power difference.

[0014] -Solution to the technical problem: torque multiplication depends on the disc radius and the length of the power arm. Flywheel components can be made from lightweight materials such as aluminum or composites such as carbon fiber.

[0015] DESCRIBE THE INVENTION

[0016] The objective of the present invention is to provide a flywheel that multiplies the torque generated by a driving power through a power arm.

[0017] The flywheel of the present invention is based on the law of the lever, applying degrees one or two to the force arm, for torque multiplication.

[0018] The law of the first-degree lever states that the fulcrum is between the power and the resistance, allowing the applied power to be much less than the resistance to be overcome, i.e., maximizing power.

[0019] The law of the lever of degree two, the resistance is between the power and the fulcrum, so the power will always be less than the resistance.

[0020] The torque-multiplying flywheel is made up of a plurality of sections, each with a disc, a power arm and a shaft. The torque is multiplied in each section, achieving a significant multiplication of torque due to the number of sections.

[0021] Torque multiplication depends on the radius of the disc, the length of the power arm, and the type of degree in the torque transmission. Depending on the manufacturer, the arm may have a curvature with certain degrees, to obtain a greater length than a straight arm.

[0022] The torque multiplier flywheel can be located anywhere in the powertrain, for example, in an automobile it can be the engine flywheel, a transmission component, a differential component, or a plurality of torque multiplier flywheels can be used in the powertrain.

[0023] The torque multiplier flywheel has numerous advantages, depending on the mechanism that was installed:

[0024] • On bicycles, it multiplies the torque generated by the cyclist, has the advantage of climbing slopes with less effort, using gear ratios that imply greater rotation speed in the drive wheel.

[0025] • In motorcycles and cars, it multiplies the torque generated by the internal combustion engine, has the advantage of climbing slopes with less effort from the engine and at the same time lower fuel consumption, using gear ratios that imply greater rotation speed in the drive wheel, without having to take the engine to high revolutions, with lower fuel consumption and at the same time generating less environmental pollution.

[0026] • In cargo vehicles, it multiplies the torque generated by the internal combustion engine, it has the advantage of pulling a greater load with lower fuel consumption, climbing slopes with less effort from the engine and at the same time lower fuel consumption generating less environmental pollution, using a smaller number of gear ratios since the torque is multiplied, having a greater engine braking effect since the deceleration torque is multiplied. • Stationary internal combustion engines; electric generators, pumps, hydraulic power unit, have the advantage of lower fuel consumption while generating less environmental pollution. The fuel consumption of an internal combustion engine can be reduced, using the torque multiplier flywheel, by an average of approximately 10% to 50%, achieving a reduction in environmental pollution.

[0027] • In electric bicycles, motorcycles, and cars, it multiplies the torque generated by the electric motor. It has the advantage of using lower-torque electric motors used in these vehicles, resulting in a reduction in energy consumption while also increasing battery life. The battery life of an electric vehicle can be increased by an average of approximately 10% to 30% using a torque-multiplying flywheel.

[0028] • In hydraulic motors, it multiplies the torque generated by the motor, and has the advantage of using a lower flow rate in the motor, resulting in a reduction in the energy used in the hydraulic power unit.

[0029] • In wind turbines, it multiplies the input shaft torque, and has the advantage of using higher capacity generators, generating higher electrical voltage.

[0030] • In a gas turbine, it multiplies the input shaft torque, which has the advantage of reducing gas or coal consumption by an average of approximately 10% to 30%, thereby reducing environmental pollution.

[0039] BRIEF DESCRIPTION OF THE INVENTION

[0040] The present invention is a torque multiplier flywheel 10 which is made up of a disc 11 having a hole 12 on the periphery, which fits with the pin 14 of the power arm 13 which has a hole 15 with grooves at the opposite end, which meshes with the grooves of the shaft 16, as shown in Figure 1.

[0041] The manufacturer has three optional types of power arms:

[0042] Figure 2A shows the force arm 13 straight, with a certain length (L), from the center of the pin 14 to the center of the hole 15, as indicated by the arrows.

[0043] Figure 2B shows the force arm 13 with a curvature with certain degrees, having the center of the pin 14 and the center of the hole 15, as the start and end of the arc trajectory, being an arm with the trajectory centered, as indicated by the arrows.

[0044] The curvature of the arm allows for greater length (L) compared to the straight power arm.

[0045] Figure 2C shows the force arm 13 with a curvature with certain degrees, having an off-center arc trajectory, starting at the center of the pin 14 and the end of the arc does not coincide with the center of the hole 15, being an arm with the trajectory of the off-center arc, as indicated by the arrows.

[0046] With the curvature of the arm, a greater length (L) is achieved, compared to the straight arm and the arm with the centered arc trajectory.

[0047] The flywheel, depending on the transmission of torque, applies the principle of the first or second degree lever, figure 3A shows the straight force arm 13 with a plurality of pins 17 concentric with the hole 15, the transmission of torque is done through said pins, the kinematic chain is indicated by the arrows in figure 4A, applies the principle of the second degree lever.

[0048] Figure 4B shows the straight force arm 13 with the grooved hole 15, the torque transmission is done through said grooves, the kinematic chain is indicated by the arrows, it applies to the principle of the second degree lever.

[0049] Figure 3B shows the straight force arm 13 with a tab 18 to reinforce the hole with the pin 19, the torque transmission is done through said pin, the kinematic chain is indicated by the arrows in figure 4C, it applies to the principle of the lever of the first kind.

[0050] Figure 4D shows complement 20, it is a disc that has a hole in the periphery that connects with pin 19, and through grooves or a plurality of concentric pins it transmits the torque in line with axis 16, the kinematic chain is indicated by the arrows.

[0051] The formula for the law of the lever is given by the following:

[0052] P - Power

[0053] BP - Potency Spleen

[0054] R - Resistance

[0055] BP - Resistance Arm

[0056] A - Support (Fulcrum)

[0057] The flywheel has two torque cycles:

[0058] Figure 5A shows disk 11 and force arm 13 at rest.

[0059] Figure 5B shows the first torque cycle, the driving power is transmitted to disc 11 which drives the force arm 13 with a length of 15 cm, from the center of pin 14 to the center of hole 15 with splines that mesh with shaft 16, the kinematic chain is indicated by the arrows.

[0060] The formula for the first cycle of moment of force is given by the following:

[0061] M = F xd T

[0062] M = is the moment of force / torque

[0063] F = is the force exerted on the force arm di = is the perpendicular distance from the center of the pin to the center of the hole in the force arm

[0064] For example, a motor delivers T 12N / m and the length of the force arm is 18cm.

[0065] M = F xd T = 12 x 0.18 = 2.16

[0066] The result is 21.6 N / m, a multiplication of the torque in the kinematic chain of 9.6 N / m.

[0067] If the flywheel has multiple sections, the lengths of the power arms are added together. For example, if an engine delivers T 12 N / m and the torque multiplier flywheel has two sections, the length of each power arm is 15 cm. The lengths of the arms are added together, which would be 15 + 15 = 30. M = F x d T = 12 x 0.30 = 3.6.

[0068] The result is 36 N / m, a multiplication of the torque in the kinematic chain of 24 N / m.

[0069] The multiplication result must be reduced by approximately 10% to 30% for the loss in torque transmission, because the difference in diameters between the input shaft and the disc is considerable and the transmission of torque through the pin on the periphery generates torque losses.

[0070] Figure 5C shows the second torque cycle, disk 11 rotates due to the driving power, dragging the force arm 13 with a length of 13.5 cm, and the hole 15 with grooves that meshes with the shaft 16 which has a diameter of 3 cm, the kinematic chain is indicated by the arrows, said force arm applies the law of the lever of degree two.

[0071] The formula for the second cycle of the moment of force is given by the following:

[0072] P x BP ■■■■ R x BR

[0073] For example, a motor delivers T 12N / m and the length of the force arm is 13.5cm, and the resistance arm is 3cm.

[0074] P x BP = R x BR

[0075] 12 x 13.5 = 162

[0076] 162 / 3=54

[0077] The result is 54N, converted into pounds of force it is 12.1394, which would be the drag force that would be on the axle.

[0078] If the steering wheel has multiple sections, the result of the first section is added to the second section.

[0079] For example, an engine delivers T 12N / m and the torque multiplier flywheel has two sections, each force arm is 13.5cm, and each resistance arm is 3cm.

[0080] P x BP = R x BR

[0081] 12 x 13.5 = 162

[0082] 162 / 3=54

[0083] 54 x 13.5 = 729

[0084] 729 / 3 = 243

[0085] The result of 243 N / m, converted into pounds of force is 54.6286, which would be the drag force that would be had on the axle.

[0086] The multiplication result must be reduced by approximately 10% to 30% for the loss in torque transmission, because the difference in diameters between the input shaft and the disc is considerable and the transmission of torque through the pin on the periphery generates torque losses.

[0087] Figure 6A shows a single-section torque multiplier flywheel 10, disc 11 has a diameter of 100cm, in many mechanisms it would be unfeasible due to the diameter and there would be greater loss in the transmission of torque, to be viable with a disc diameter admissible to the mechanism, the disc diameter is divided into a practically viable diameter, for example, in figure 6B, it shows a two-section torque multiplier flywheel 10 S-1 and S-2, each with discs 11-1-2 with diameters of 40cm, it is reduced by more than half compared to the disc with a diameter of 100cm, and said discs with a diameter of 40cm are more efficient in multiplying torque.

[0088] Figure 6B shows that the first force arm 13-1 applies the law of the lever to the degree two and the second force arm 13-2 applies to the degree 1, the type of arm or combination of arms and the degree that applies to the law of the lever will depend on the manufacturer of the torque multiplier flywheels of multiple sections.

[0089] It will depend on the manufacturer whether the plurality of discs will have the same diameter or a combination of discs of different diameters.

[0090] Figure 7A shows the periphery of the disc 11 with the hole 12 with the pin 14 with a certain clearance H, and between the hole 15 of the force arm and shaft 16 it must also have a certain clearance. It is very important that all the components of the torque multiplier flywheel have a small clearance to prevent the driving power from passing like a bridge from one component to another, and the multiplier effect would be lost. The manufacturer can also use friction washers to prevent the components from being integral, losing the multiplier effect.

[0091] Figure 7B shows the periphery of two discs 11 and the power arm 13 with the hollow pin 14, it is a two-section flywheel, when transmitting the torque of the disc through the pin to the power arm, axial forces are created by the effect of resistance between the components, causing the disc and arm to move axially away in opposite directions, to counteract this axial force the axial control pin 21 is used, preventing the package of discs and arms from moving axially away, said axial control pin has stops at the ends.

[0092] Figure 8 shows the diagram of the kinematic chain of a vehicle, in the first stage is the engine M, the conventional flywheel is replaced by a torque multiplier flywheel 1, in the second stage is the speed transmission T, with a second torque multiplier flywheel 1 incorporated, the third stage is the differential D, with a third torque multiplier flywheel 1 at the input and at the output at the end of the axles. The manufacturer will determine in the kinematic chain of each mechanism, the number of torque multiplier flywheels and the location for the greatest efficiency in the multiplication of torque.
