Description

BICYCLE FOR SYSTEM ELECTROMECHANICAL MOTOR Sphere of technology The sphere of technology, to which this bicycle system for electromechanical motive system belongs, is that of electromechanical systems.

BACKGROUND OF THE INVENTION The current state of the art for bicycles is of the conventional type, that is to say the standard bicycle, with its variants of speeds, or fixed speed, of all the dimensions of tires and sizes of tires, for track and mountain in its types of sporting uses, of competition, or of light and economic transportation, but, its application as a means of transport has been of little use, in spite of being, useful little spacious and durable, in the majority of the cases this is motivated , for the little physical capacity that is had at the beginning of its management, for which its use is limited and demanding.

Object of the invention But, in order to improve their uses and the efficiency of people's physical capacity, design an electromechanical motor system, which adds a force to the movement, which consists of a motor, mechanism and batteries that are adaptable to the bicycle in the rear rim in the form of a module, with the ease of converting the track or mountain bike into a new light and fast rechargeable and rechargeable electric vehicle, which achieves greater confidence and performance in the motor movement, in the conventional bicycle, with or without speeds, adaptable to all its measures and types of common sizes and standards.

Brief description of the figures In order to give a better understanding of this electromechanical motor system, I refer to the 4 figures presented with drawings and reference signs to indicate the parts.

Figure 1 shows an overall view of the equipment, that is to say the bicycle for the electromechanical motor system, indicating the points of attachment of the module, in (1) and (2) with the use of the screw (3) that fastened in the bracket (3 *) of the bicycle seat (48) with the nut (6) and (6 ') that fits on the rim (22) in the frame (6"), the control system is placed from the module to the handlebar of the bicycle, with the conductors in the tube (40) to the 3-way control (31) in the handle of the bi-clcleta (48) with the clamp (46), and on the mechanism , the dust cover (49).

Figure 2 shows the joint area (1), (2) the nut (6) and (6N) the clamp (3N) the frame (6") and the tube (40), as well as the general view of the drive system electromechanical.

In figure 3 I describe separately the parts that make up the module of the electromechanical motor system, with reference number to indicate the parts in the description.

In figure 4 we have an outline of the relation of the diameter measurement of the pulley (13) the rubbers (io) and (15), and the power developed by the batteries (9) and (10).

Description of the invention The description will be based on Figure 3, showing the part and the reference number.

Taking advantage of the fact that it is easier to move a moving weight, than at rest, this electromechanical means, through an electric motor (12), I add a force that is transmitted by a mechanism, to the rim (22), controlled in a way electrical by a 3-way button (31) monterred by means of analog or digital type of voltage, electric charge and speed (50,) where the description of the parts and the connected electrical circuits for such purpose, is described as follows .

Starting we have a base type portabultos (7), which can be welded to the points (45), a container base for batteries (8) with two screws (8") welded on each external side, to form the base main container that we will mention separately in this description as (7) and (8).

To place the batteries of 6 Volts (9) and 12 Volts (10) respectively, which are placed between them rubber separations (1 1) to the size of the batteries side and bottom, making a package in cube that the said battery container (8) penetrates.

Forming the battery bank (9) and (10) which is stopped by 4 sides of the container (8) and up by a band (8") contactel of 3 inches minimum, which embraces from below through the battery container ( 8), to connect.

An electric motor (12) that generates a torque that develops a force that is transmitted to a pulley (13) held by a captive screw (14) to the arrow of the electric motor (12) to which is covered by a band rubber (15) and (16) glued to the pulley (13). which moves the rim (22) when transmitting the force through the pulley (13) of 3cms. in diameter, and covered at 4 cm. with a range of different powers, between 3 and 4 cms. that allows a variable or customized design that is required depending on the bicycle track, engine power or battery bank capacity (9) and (10) Its use between 3 and 4cms. of diameter in the pulley (13) keeps the mechanism simple and in this type of light vehicle it is ideal, since it allows to have little additional weight and the effort is covered with the transformation of electrical energy into mechanical and vice versa.

The rubber is wearing elements in this model, the outer rubber (16) wears every 30 km on average on the track and 15 km. in dirt, as this happens the rubber (16) is separated from the rubber (15) and the power increases, when the rubber (15), the power is greater, but you can suffer from patios at low speeds which could heat friction rim (22) and rubber (15), that before the sudden braking, could cause premature wear between the rim (22) and rubber (15) so it is recommended to place a new external rubber (16) or two, for a longer duration.

The motor (12) is placed on the rear side of the rack (7) made of two round plain rods (7") with intermediate reinforcements where two of its supports (12V) are coupled by two hearth U-clamps (17) are coupled to the motor (12) to the rod (7X) positioned with the screw (18) and washer metal flat knurled (19) and nut (20) screw (18) between supports (12) and clamp hearth ( 17) flexible metal which in U is fixed to the motor (12) on one side, which allows a free rotation on the rod (7 ') keeping aligned in the direction of the pulley (13) with the rim (22), in whose position of the pulley (13) and motor (12), the gravity does not exert sufficient adhesion and traction force to the rim (22) so that a tension spring (21) is placed on the support (12") 2. ) so as to increase the adhesion of the rubber of the pulley (13) to the rim (22) which, when operated, thus adds an additional force that increases the efficiency of displacement. on the bicycle by means of the force exerted by the traction of the force of the motor (12) that works with a manual control, by means of a 3-way button (31) placed on the handlebar of the bicycle with the clamp ( 46), and electronically with the addition of new circuits (50) adaptable to the control system.

This assembly is covered on 5 of its sides with 3 plastic plates molded in a single piece removable, comprising an upper cover (23) made of 3 sides and pierced by 2 holes that fit into the screws (8) of the container of battery (8) on its front, welded at the points (45) on the outer side in a perpendicular manner, which fit with the two holes of the upper cover (23) and one on the rear flange of the cover (23), that qjusta screw (24) welded to a crosspiece of the carrier bundle (7) with rubber washer (25) flat washer (26) and nut (27), the covers (23), (29) and (30) they are protected at their edges, by rubber packing (28) and together serve to protect the internal elements from the elements.

On the sides are placed the plastic side covers (29) and (30) blown or molded, the right cover (29), have a double towards the center of the set and have two holes that fit in the screws (8 '), the left (30) also fits the perforations in the screws (8V) with the rubber washer (25), flat washer (26) and nut (27), in the right cover (29) there is an opening semicircular that allows to see the rear part of the engine (12), this makes the function of dissipating the heat that prevents heating that can decrease the performance of the electrical operation.

This module is controlled by an electrical circuit comprising, as can be seen in Figure 3, various elements that I indicate with reference signs to explain their use and application.

First of all we have the 3-way control button (31) installed on the handlebar of the bicycle (48) with the clamp (46), which serves to discharge the electrical energy, in the use of the motor (12) that to transmit the power through the mechanism, it is used to interact with the speeds of the bicycle, starting its operation with the pedaling impulse, from the chosen speed, and it must be gained po-. power before starting the engine (12).

Just an advance of 1 to 2 meters. to be able to apply the force through the 3-way button (31) and start to gain Speed, which allows to make the progressive changes of speed, until achieving the greater range to gain more inertial force and greater speed, or to return to the short speeds to gain power, before total braking, the system must be turned off, and to restart its use, it is repeated in the same way.

The manipulation of the button (31) is done with the thumb which is the closest to the grip position of the handlebar and the control. 1 path of the 3-way control button (31), supplies the motor (12) of the universal type, with a range of 6 to 18 volts., Positively, connecting it through the conductor (32) to the battery bank, connected in series by the driver (32") that closes the circuit with the negative to the motor (12) through a conductor (34") with a safety button (34) installed in the right side cover (29) followed by a fuse holder (35) with a 20 amp fuse. (36) connecting the motor (12) safely against short circuits, and another circuit, comprising a conductor (37) installed between the positive of the motor (12) and track 2 of the 3-way button (31) with diode (37") serving as a valve for the current generated by the motor (12) when moved by the rim (22), out of electrical use, the mechanical energy that transmits the movement to the pulley (13) makes it a generator (12) so the electricity with a voltage passing through the diode (37?) is accelerated in series by the 9 volt battery (39) installed on the side of the rechargeable batteries, which raises the voltage generated from 8 volts to 27 volts by recharging the battery bank (9) and (10) by connecting the generator positive (12) to the battery positive ( 9) by increasing the effective use time with respect to the pedaling, the diode (37") does not allow current backflow, so the motor (l 2) does not work in this position of the button (31).

The amount of current and voltage may vary with the speed, if a current of 0.5 amp is generated. +/- 30% at 25 volts and the consumption current is 3 amp. on average, it could be said, that it allows us the capacity to have an average recharge of, for every minute of electric operation, 6 minutes of the recharge in the pedaling are required, as well as an electric charge of 7 amp. hr. It lasts about 2.20 hrs. downloading 3 amp. continuous, would require 13.2 hrs. of pedaling for a 100% recharge, so it would be better to travel 50% electrically assisted and 50% human having a service of 4.4 hrs. and if so we take into account the energy generated from the recharge of 1/6, it is maintained or increases up to 5.13 hrs. useful combined tours, which increases to save more energy in the motor discharge, and save time, if the routes are used with more than 90% electrical assistance, the system does not charge and remains in 2.2 hrs. the performance of the battery bank on average.

The recharge in the electrical service, is according to the recommended time of batteries (9) and (10), and in order to protect the interior, over the mechanism is placed a dust cover (49) to retain dust in a smaller space and garbage from the interaction of the rim (22) with the pulley (13), and keep the rest of the mechanism clean, it can be removed to wash and it is placed under pressure between the upper cover (23) and the container (8).

The relation of the force with respect to the diameter offers important data in the use of the assembly of the pulley (13) with the rubbers (15), (16), and the battery bank (9) and (10).

The power is reserved for the lower measurements, that is, there is more force in the pulley (13) towards the center and lower battery bank (9) and (10) the power is more balanced with the wear of the rubber (16 ) and (15) providing proximity to smaller diameters with respect to the decrease of the potential of the battery bank (9) and (10) with which the power extends the force to lower voltages.

In drawing 4 on the bottom line of the Cartesian plane, we have the diameter in cm. it also represents the pulley (13) covered, and in the left line we have the power where the point of union zero represents the maximum force of the engine (12), and the area marked up to 3 cms. to the battery bank (9) and (10) in Qoulones, between 3 cms and 3.8 cms. the rubber (15) and between the 3.8 cms. and the 4 cms. the rubber (16) wear-table, the power is very sensitive to the measurements in mm.

The best method to execute the invention The best way to carry out the invention, is with the mastery of the common tools of an electromechanical workshop, which has the facilities of assembly and assembly in progressive areas of manufacturing, ie building from the base, the pieces can be purchased on the market, except for the pulley (13), the battery container (8) and the covers, upper (23) and lateral (29) and (30), which are manufactured around to the extent required up to the 3cms., in the case of the pulley (13), and in the case of the covers (23), (29) and (30) of the acrylic type previously cut to the measure that is required, it is cast or blown in mold , the general connection requires previq experience in circuits of direct current, welding and general mechanics. -Yes- The possibilities of use or application The possibilities of utility are very wide, since it is applied in a practical way to this means of transport, an advantage of electromechanical driving type, before the other bicycles without the mechanism, either on track or mountain with or without speeds, of design for men or women.

The weight of the equipment is 5 kilos that is compensated with the power developed, so that its use does not lose its attractiveness, and before an eventual carry of the equipment, the effort is minimal.

At the moment of applying the recharge, some resistance is opposed, but it is not cause for discouragement in its use since the applied effort is minimal.

Its usefulness is broadened by the need for fast, efficient and light means of transport.
