Description

SPEED AND FORCE MULTIPLIER DEVICE

Throughout history and since its creation in the middle of the 19th century, this vehicle, the bicycle, has been very useful for people from different countries. It has had different modes and forms of use, both as a means of transport and as a leisure vehicle, suitable for walking, sports, and children's recreation.

Its use entails numerous advantages from an economic point of view, not to mention its ecological perspective or its contribution to the physical well-being of the user.

The Speed and Force Multiplier system described here is the result of a detailed analysis and research that aims to improve this useful invention to increase the benefits that it can offer to its many users. Over time, different models of bicycles have been developed, adapting them with various types of gear mechanisms. Some with gasoline engines, others with electric motors.

In view of the need to contribute to not polluting the environment, a pedal-powered vehicle device has been developed to obtain a higher speed that is not only useful for the daily service of man but also to improve the physical and mental part of the body. user and that can also be used in the sports environment.

The research that has been carried out has been over 10 years with different drawbacks such as in the case of real tests of the system, and calculations with different mathematical and physical formulas to correct errors and excesses. I have had to put together and take apart many occasions to change and come to the concrete and fundamental conclusion of the idea.

This created system can be used in the case of a racing bicycle, with a higher speed than any other bicycle executed with pedals, that exists in the present.

General description.

This system comprises four strength elements (1-3-5-7) and four speed elements (2-4-6-8), incorporated in the position of the bicycle frame. The beginning of this is the pedal (19) and the final element (8) on the right side that is compact to the rear wheel of the bicycle, where the multiplied force is concentrated, which contributes to a substantial improvement in the operation of the entire system. system.

Not only will the established measures be applied in the system, but it will also be adjusted to the needs of each vehicle in which it is implemented. For example, if it is applied to a racing bicycle, it will be necessary to dimension a larger diameter, the size of the elements will be reduced and it will have a smaller number of teeth.

On the contrary, if the bicycle were smaller, the diameter of the force elements (1,3,5 and 7) would be reduced, the size of the speed elements (2,4,6 and 8) would be increased and the also the number of teeth.

The main idea that is the form and technique that is applied in the system is maintained (Figures 5, 6 and 7), but it is adapted to the size, shape and expected speed of the vehicle. Sometimes the system will be adapted to the bicycle frame, other times it can be incorporated in the rear between the two rear wheels, as is the case with the tricycle.

In order to avoid the inconveniences that could be generated with the installation of this system in the vehicle, it will be protected by a surrounding element adhered to the plastic or metal frame (22) (Fig. 3). This will avoid inconvenience to the user and increase his safety.

Description by Elements. First force element (1) (Fig. 1)

The first force element (1) is the unit where the bicycle user pedals, it has a diameter of 21 cm and 52 teeth. The first force element (1) has a left and right connecting rod (21) attached to it, each one with its pedal (19) and assembled to the axle with the usual bearings of the original bicycle. These mechanisms are anchored in the lower tube of the frame, in the frame (17). The force that moves the rest of the mechanism and exerts a force according to its diameter and number of teeth is exerted on the first force element (1). Its location should be set 30 cm from the pedaling point of the original bicycle.

First speed element (2) (Figure 1)

The first speed element (2) (Fig. 1, 2, 6 and 8) has a diameter of 8 cm and 18 teeth, and is attached to a second force element (3). This first speed element (2) is connected and receives the force of the first force element (1) by means of a link chain (10) exerting a speed of 2.89 rpm when the first force element (1) gives a turn .

The first speed element (2) and the second force element (3) are attached by means of an axle and a bushing (12) to a triangular support (23) (Figure 3) that is adhered to the upper tube of the frame (Point A ) (Fig. 4).

Second force element (3) (Figure 1)

It has a diameter of 21 cm. and 52 teeth. Its speed is 2.89 rpm just like the first speed element (2). The second force element (3) is linked to the first speed element (2) by means of a hub axle system (12) to a triangular base (Figure 3) implemented in the upper tube of the bicycle (Point A) (Fig. 4). It is a simple mechanism to shorten its weight and dynamics. This second force element (3) exerts a force due to its size that is transmitted to a second speed element (4) and are linked by a chain (16) (Fig. 6, 7 and 8) that transmits the force from one to the other.

Second speed element (4) (Fig.1)

It has a diameter of 8 cm and 18 teeth. When connected, it receives the force through the link chain (16) from the second force element (3), thus acquiring a speed of 8.35 rpm, thus increasing the speed range from 2.89 rpm to 8.35 rpm. and being compact with a third force element (5) it generates a force and speed greater than that of a third speed element (6), with which it is linked by means of the link chain (18). (Fig. 6, 7 and 8)

The second speed element (4) is linked to the third force element (5) through a system of axles and bushings (13) to a triangular base (Fig.3) implemented to the vertical tube of the bicycle (Point C) (Fig . 4).

Third force element (5) (Figure 1).

It has a diameter of 21 cm and 52 teeth. Due to its diameter, it exerts a force on the third velocity element (6) (Fig. 6, 7 and 8). This third force element, (5) being compact with the second speed element (4), rotates at the same speed of 8.35 rpm enabling the third speed element (6) with a greater speed and force.

Third speed element (6) (Figure 1)

It has a diameter of 8 cm and 18 teeth. This receives all the force and speed of the third force element (5), thus ending the system. It is located directly on the frame (17) that forms the bicycle frame where the axle and bearing (15) are located, the same one that is on the left, which in turn makes a fourth element rotate ( 7) of strength that is located on the right side. This third speed element (6) receives the force of the third force element (5) by means of a chain with which they are mutually linked, acquiring an ascending speed of 24.13 rpm.

Fourth force element (7) (Figure 1)

It measures 21 cm and has 52 teeth, and due to its diameter it causes a greater force and at the same time the force and speed it receives from the third speed element (6) of 24.13 rpm. You can transform it at a speed of 69.73 rpm into a fourth speed element (8).

Fourth speed element (8) (Figure 1)

It measures 8 cm in diameter and has 18 teeth, and it is connected to a chain (20). It is the one that receives all the action of the system, so that it turns from the first force element (1) to the fourth speed element ( 8) a speed of 69.73 rpm is obtained.

The elements described above are grouped together in a series of modules that are described below.

Module A of figure 2.

The first module is composed of the following elements:

• The first element (1) of force:

• Two connecting rod arms (21);

• Two pedals (19);

• Two bearings and one shaft (9) each one of them integrated to the connecting rod arm (21);

• The first speed element (2);

A link chain (10) linking the first strength element (1) and the first speed element (2) Module B of the (Figure 2).

The second module is composed of the following elements:

• The second force element (3)

• A first bushing (12) in figure (6, 7 and 8) that is integrated in the second force element (3), compacted with the second force element (2) (point A) (figure 3).

• A shaft that goes inside the previous hub (12) and welded to the triangular support (23) (figure 3).

• The triangular support (23) (Fig. 3) that is welded to the upper tube of the bicycle frame (Fig. 4).

• The second speed element (4); Y

• A chain (16) that links the second force element (3) to the second speed element (4) of the second (module B) (Fig. 2).

Module C (Figure 2)

The third module is composed of the following elements:

• The third force element (5), which is attached to the second speed element (4) of the second module B.

• A second hub (13) that is integrated into the third force element (5) and the second speed element (4)

• A shaft that goes inside the second bushing (13) and is welded to the triangular support (23) (Fig. 3).

• The triangular support (23) (Fig. 3) that is welded to the vertical tube of the bicycle frame (Fig. 4).

• The third element of speed (6)

• A shaft (15) that drives and supports the third speed element (6) (Fig. 6, 7 and 8), by means of two bearings that drive their movements to the fourth module D. • A link chain (18) (Fig. 6, 7 and 8), which links the third force element (5) to the third speed element (6) of the third module.

Module D of figure 2.

The fourth module is composed of the following elements:

• The fourth force element (7), which is attached to the shaft (15) and the bearings to the third speed element (6) from which it receives the force and speed and which is located in the lower frame (17) of the frame. of the bicycle.

• A chain (20) that links the fourth force element (7) with the final fourth speed element (8), which rotates like the rear wheel of the bicycle, executing the action of all the revolutions caused by the system. Speed and Strength multiplier.

The four modules (A, B, C and D) (Fig. 2 and 8) that make up the system ensure complementary development in a satisfactory job, whether on a bicycle, tricycle or quadricycle for which this system has been invented. according to the speeds of these vehicles.

Each module has a force function, progressively.

The tables that are presented will be objects of application for each vehicle, some with greater security, others with less speed; but with more force, the truth is that they are for benefit according to need.

It is considered that there are systems as in the case of wheels with gears that work following their circumference in an ascending and descending manner according to their utility.

The new system of large toothed elements and small toothed elements has a different feature for its proper operation. The linking speed elements (2, 4, 6 and 8) are also compacted with larger force elements (3, 5 and 7), in order to rotate at the same speed, that is, the small element favors speed and the large element generates force, thus consecutively to the rest of the elements that make up the system. From another point of view, if the element were directly linked by means of gears, it would lose its speed, but if it would generate force.

Then, the difference between the invented system and previous systems would be consistent.

The support (23) (Fig. 3 and 4), is where the elements (2 and 3) and the elements (4 and 5) are located, it has been designed with reduced dynamics and weight, facilitating the stability of the vehicle. Its dimension is according to the frame of each bicycle. This mount is welded to the frame tubes at three key points (A, B, and C), for better system performance. It is also equipped with two shafts (figure 12 and 13) that are attached to the base of the support (23) on which the bushings that hold the elements (Point A) (2 and 3) and (Point C) ( 4 and 5).

Example of calculations of advance of the vehicle (bicycle) with the Multiplier of Speed and Force.

We start from the case of a two-wheeled bicycle (Figure 5) with a diameter of 63 cm each.

The rotation of a complete revolution of the two wheels of the bicycle implies an advance of 1.98 linear meters. As the result of a single turn of the first force element (1) that performs the function of the drive wheel executed by the user, it is the result of 69.75 rpm in the two wheels (Figure 5) of the original bicycle, it is deduced that the progress achieved by the vehicle would be 138.10 linear meters.

If we apply 10 revolutions to the first force element (1), the distance traveled would be 1381 m. The result of the force conversion supplied by the 4 force elements (1, 3, 5 and 7) of the Speed and Force Multiplier system, which have a diameter of the wheels (Figure 5) of the bicycle, each one of 21 cm the same ones that, added together, exceed the diameter of the bicycle, which measures 63 cm. This makes it compatible with the traction force of the vehicle and facilitates its movement and performance.

It is essential on sloping terrain when the difference in displacement is most appreciated. The user will obtain a more significant return on the effort invested in moving, avoiding efforts that are often exhausting.

With this system when changing the chain in the first force element (1) of the pedal, the difference in speed and force is caused when the user makes the change to the larger element, more speed is obtained from the bicycle or vehicle ; but the user tends to apply more force to their legs.

When the user makes the chain change towards the element with less diameter, the difference also arises that the user has to pedal more laps to acquire speed of the vehicle (bicycle), as it also denotes less force, at that moment he also loses speed this happens on sloping ground. That is when the advantages of the new system are appreciated, tripling the speed and force that the system generates to the invented vehicle, replacing that work to the user.

This system has been designed to carry out its work on any terrain, with slopes or with greater progress difficulties, where the user does not have to make much effort to climb, taking advantage of their speed and time.

4.- Calculation of the Speed and Force Multiplier system

The Speed and Force Multiplier system is not only designed to be applied to a single bicycle model, that is, to a 2-wheel bicycle, but also to It can also be installed on a three-wheeler or even a four-wheeler, as in the case of Fig. 7.

In these cases, the Speed and Force Multiplier mechanism can be installed in the different positions required by the vehicle. In addition, some regulations and dimensions of the elements will be made according to the required speed without changing the original idea of the invented system or device.

The objective is to give priority to the best development of speed and strength without the user having to make greater physical effort when driving the vehicle.

Each element of the Speed and Force Multiplier system is established based on the following formulations.

As is known, the perimeter of a circumference is determined based on the formula: 2*TT*R

Transmission ratio:

We name the following concepts as described below:

N represents the rpm of the element.

D is the diameter of the element.

Z is the number of teeth of the element.

In relation to the elements of the Speed and Force Multiplier system, we establish the following definitions:

N1 are rpm of the driving or driving element.

N2 are rpm of the conductive element.

D1 is the diameter of the conductive element. D2 is the diameter of the driven element.

Z1 is the number of teeth on the driving element or drive wheel.

Z2 is the number of teeth on the driving element or drive wheel.

After these definitions we can fix the following relationship.

N1/ N2= D2/ D1= Z2/ Z1

For the following values:

N1= 1rpm

Z1= 52 teeth

Z2= 18 teeth

It follows that N2= Z1 / Z2, that is N2= 52/ 18 = 2.89 rpm of the driving element.

Transferring the same calculation to the third wheel, the rpm of the driving element would be 2.89*2.89 = 8.35 rpm of the second driven wheel.

And after a third lap, a value of 24.13 rpm would be sent to the original system of the bicycle.

Summarizing the above, we would have the following table to obtain speed and strength:

From another point of view, applying other formulas, it can be calculated as in the case of the frequencies of corresponding elements that are used in the new mechanism of the device in relation to different diameters to regulate the speeds and forces that it requires; always following the idea of the main invention.

For example:

2 elements of 6 cm and 10.5 cm radius respectively rotate connected by a band, if the frequency of the largest radio element is 1 revolution per second, what will be the frequency of the smallest radius? r1= 5 cm Vi= (2 X TT X r)/ T f= 1/ T r2= 10.5 cm V ₂ = 2 X IT X r X f f2= 1 lap/sec 2 X TT X n X f1 = 2 X TT X r ₂ X f ₂ f1= ? HX fi= r ₂ X f ₂ fi= r ₂ X f ₂ / n fi= (10.5 cm X 1 turn/sec.) / 5 cm fi= 2.1 turn. / sec

The way it is installed in a quadricycle differs from a bicycle or tricycle, this new system, by having the four modules that make up each large element and a small element, they are in the form of signs that involve a dynamic of force and speed coherent in the figure (Fig. 7) each element is shown in a decisive way, the elements (1, 3, 5 and 7) are the ones that converge the force that is needed not to lose autonomy and each one forms an important role in its functioning.

The work is done by the four force elements (1, 3, 5, and 7) that generate a superior force.

Now we talk about the four speed elements (2, 4, 6 and 8) (Fig. 6, 7 and 8) these elements enable the respective speed that we need for the vehicle each one rotates according to its position as it is in the first speed element (2) this rotates at 2.89 rpm. The second speed element (4) rotates at a speed of 8.35 rpm. The third speed element (6) rotates at a speed of 24.13 rpm. And the fourth speed element (8) rotates at a speed of 69.75 rpm. In other words, the speed it generates is carried out in an ascending manner, the vehicle reaches a satisfactory result.

In addition, it is made up of shafts (9, 12, 13 and 15) (Fig. 6, 7 and 8) as well as the bearings that hold the elements of the system are located in the frame (17). Also the chains that make up the Speed and Force Multiplier are four (10, 16, 18 and 20) (Fig. 6, 7 and 8) and their dimension according to the distance of each module, will always vary according to how the modules are installed. slower systems.

It is important to present the new system in a quadricycle (Fig. 7) in order to describe a different form of the one that has the mechanism installed, which is not the same as in a bicycle, here you can see in figure 7 its elements and modules that make up the system; they are in series, that is to say one after the other, because of their space is relative to the vehicle.

The function is to enhance the work capacity of the quadricycle, each module has a force and speed, as in the case of the first module that generates a speed of 2.89 rpm, the second module of 8.35 rpm, the third module generates a speed of 24, 13 rpm, and the fourth module generates a speed of 69, 73 rpm.

It has the same operating characteristic of the system that is installed on the bicycle, that is, as the form of a driving wheel and an element, in the same way the elements are compactly adhered to the three sprockets, and the final element is compact to the wheel of the vehicle and obviously with chains to transmit the respective revolutions.
