The mid-wheels are fastened by two pins fixed in two rectangular pieces installed in the parallel surfaces of the wheel, these two parallel pieces being installed by a perforation in the mid portion of the shaft, the two mid-wheels generating centrifugal force due to their arrangement, which is applied, with lever characteristics, by exerting pressure in the rotation direction in the opposite end portions of the rectangular piece that is fixed to the shaft, thus obtaining a torque increase.

Description

DETORQUE MULTIPLIER STEERING WHEEL Field of the Invention The present invention relates to a device coupled to power transmission shafts from motors, which by means of the rotation the device of the present invention produces centrifugal force, this centrifugal force is applied with characteristic of lever, making pressure of torque in the axis that turns the whole system thus achieving an increase in torque.

There are several proposals in the prior art to improve the use of energy that is fed to a conventional mechanical system such as those in which a motor drives and maintains the rotary movement of another machine to which it is coupled by an axis or transmission or arrow . In almost all cases, use is made of moving elements that project outside the boundary of the rotor axis in order to increase the lever arm, modifying the center of mass of the rotation assembly, and therefore, increasing the energy of the rotor. rotor shaft.

In mechanics, it is called torque, moment of force, momentum, torque (or simply moment) to the magnitude that is given by the vector product of a force by a director vector. The moment of force is equivalent to the motor torque, that is, the force that must be done to move a body with respect to a fixed one and is conditioned by mass and distance. The moment of a force with respect to a point reveals to what extent there is a tendency in a strength or imbalance of forces that can cause the rotation of a body with respect to it. The moment tends to cause a turn in the body or mass on which it is applied and is a characteristic solicitation in working elements subjected to Torsion (like the axes of machinery) and in working elements subject to bending.

Some examples of the devices that apply these principles are the following: A simple device is described in U.S. Patent No. 203,623 (Jay, 1878), where a device aimed at preventing the wheels of a machine from resting on a dead center, and imparting them a more uniform movement, includes a plurality of devices. counterweights that are located and move in such a way that they are always located outside the center of mass so that when the wheel approaches the rest, these counterweights located outside the center of mass, impel the wheel to continue moving.

U.S. Patent No. 3,424,026 (Vaughn, 1969) describes a device with a flywheel through which mechanical power is transmitted in such a way that an increase in torque occurs by cyclically changing the center of mass of a rotor during its rotation. Counterweights mounted pivotably in a sliding manner on the end of the rotor are used, so that the movement of said counterweights is influenced by centrifugal forces that move them "outwards" of the rotor limits, and their projection is controlled by means of operating levers in response to rotor rotation.

A similar application is that in the Japanese patent JP08- 109867 (Ligami, 1996) which describes a device that to obtain an increase in the rotational force of the transmission shaft of a motor, engages a plurality of L-shaped arms around the shaft, and counterweights are included at the ends of said arms so that the tangential end of the arms and the counterweights act on the shaft as a lever.

On the other hand, U.S. Patent No. 4,811,625 (Sorg et al, 1989) makes use of a similar device, with a controllable handwheel including a plurality of counterweights so that it is possible to conserve energy (movement) in a spinning wheel; The device also allows controlling the Fluctuations in the movement coming from the application of impulses to move the wheel.

In the previous examples, the counterweights are projected outwards consecutively, so that their weight, outside the center of mass of the original arrow, produces a new impulse that maintains the axis of rotation; after performing this action, the counterweights are normally resumed to their original restricted position through the use of control levers.

In an alternative application shown in U.S. Patent No. 5,085,088 (Robinson et al, 1992), a power train is described in which a flywheel with a series of counterweights is included, which unlike previous applications , are projected simultaneously out of the steering wheel once the desired speed is reached, so that the momentum of the assembly is increased to help maintain the speed of the vehicle in which the device has been installed, when it moves at high speeds.

Note that, in all the cases mentioned, the counterweights are coupled to the steering wheel by means of mechanisms that allow their movement towards the center and outside the perimeter of the steering wheel, normally springs and levers that are elements susceptible to mechanical failures; the counterweights act, offering an additional impulse, only when it reaches a predetermined speed of the steering wheel; in addition, the counterweights are relatively small, so the additional momentum when deployed is low.

SUMMARY OF THE INVENTION In light of the limitations and problems presented by the developments proposed up to now in the prior art, it is an object of the present invention to provide a device which can be coupled to the arrow of a conventional motor, which makes it possible to take full advantage of the energy offered by the motor towards a team, said device being arranged in such a way as to increase the torque offered by the engine.

It is an object of the present invention to offer a device for increasing the torque of a motor, whose action does not depend on the speed of rotation of the arrow, but operates constantly throughout the range of speeds. From the start to the maximum speed.

It is still another object of the present invention to provide a device for increasing the torque offered by an engine, based on two levers that lack moving parts for their operation, which requires low maintenance.

It is still another object of the present invention to provide a device for increasing the torque offered by a motor, wherein the levers do not require additional space for their operation.

Brief Description of the Figures For a better understanding of the advantages of the device of the invention, a series of drawings and figures are now presented which aim to illustrate illustratively the characteristics of the device and the way to use it, without pretending to be limiting.

In fig. No. 1, the three parts that make up the torque multiplier are described, in a front and profile view, (1-1), (1-2), (1-3).

In Fig. No. 2, the placement of these three parts is described schematically in front view, so that the piece (A) and the two pieces (D) that are installed in parallel position on both sides of the multiplier of torque see fig (3), they are connected in the arrow of a motor (E) or of some device that puts them in rotation.

The piece (A) is connected as the two parallel pieces (D) in the arrow of the engine, the pieces (B) are on the sides of the piece (A) to together form a steering wheel.

The pieces (B) that we will call levers are connected at the ends of the two pieces (D) by means of bolts (5).

See in fig. No. 3, the entire Torque Multiplier device is described in profile view and its different parts installed in the arrow of an engine (E) or the device that puts it in rotation.

Detailed description of the invention The following description will be referred to the accompanying drawings described above, which should be understood as illustrative of the invention, and not limiting of the scope thereof. The common elements in the figures have the same numerical references in all of them.

The present invention relates to a torque multiplier coupled to an arrow of a motor (E), the device comprises two levers installed in such a way that once the motor starts its rotation, the device acts to increase the torque. To better understand the operation of the device, each of the elements that comprise it is described in detail.

Fig. (4).

In this figure we indicate the operation of the torque multiplier.

The piece (A) and the two pieces (D) that are placed in a parallel position and placed on both sides of the torque multiplier see fig. (3), are fixed on the arrow of an engine (E) or of the device that sets them in motion with the inclination indicated with respect to the part (A) indicated in fig. (2).

The two pieces (B) are connected only through the bolts (5) that are fixed at the ends of the two pieces (D).

Because of the position in which the pieces (B) are installed in the bolts 5, once the multiplier starts to turn, the pieces (B) generate centrifugal force in the direction of the arrows (C); This centrifugal force produces the characteristic of lever (P), see parallel lines in the two parts (B) having as a point of support the bolt (5) in which they are installed and applying lever force in the corners (F) of the piece (A) in the direction of rotation, this produces another lever effect on the part (A) by applying torque pressure on the shaft (E), this lever effect on the part (A) results from the considerable distance there is between the part (E) in which the system rotates and the points at which the pressure F is applied so that the piece (A) acts as a double lever and applies torque pressure in the direction of rotation. See parallel lines and arrows (R).

As to any action corresponds a reaction in the opposite direction, in this device to the pressure of the levers (B) that is applied at the point (F) in the direction of rotation corresponds a pressure against the bolt (5) see arrows (H).

This pressure in the direction opposite to the rotation (H) is nullified by the fact of being applied simultaneously in opposite directions (H) (H) in the two bolts (5) that are fixed only in the two parallel pieces (D) ) and by the fact that these parts (D) are fixed in the axis of rotation of the whole system (E) thus neutralizing the counter-lever force and therefore the centrifugal force (C) of the parts (B) ) is applied as torque pressure in the direction of rotation in points (F) with lever effect and the lever locknut (H) (H) is nullified as indicated above.

This effect occurs in all speed ranges and the torque pressure increases when the speed of the whole device increases due to the fact that the parts (B) increase their mass when they increase their speed (increase in weight), this produces a greater pressure with effect of lever in the points (F) of the piece (A), this pressure of torque increases exponentially to the speed.
