Description

TITLE

[01] Self-Propelled System for Generating and Supplying Energy

FIELD OF THE DISCLOSED TECHNOLOGY

[02] The disclosed technology relates to a self-propelled system for generating and supplying energy that efficiently generates output energy for supply to a separate external system, such as an electric traction motor, via input energy initially applied to the system, that is renewable by the self-propelled motion of the system.

BACKGROUND OF THE DISCLOSED TECHNOLOGY

[03] Internal combustion engines have a long history. They are considered complete and functional machines that produce mechanical energy. Despite the associated problems (e.g. increased levels of C02, energy crises, dependency on the oil industry, air pollution), they are still essential and can be manufactured in different configurations and in a wide range of size and power.

[04] The history of the automobile began with self-propelled steam vehicles in the eighteenth century and very soon the steam system was replaced with the internal combustion engine. Now, it looks as if the electric motor is poised to replace the internal combustion engine in the automobile. Indeed, engineers are looking at ways to improve the electric motor.

[05] Accordingly, there is a need for a self-propelled system for generating and supplying energy that can efficiently generate and renew output energy for use by an electric traction motor such as to provide energy to an electrical grid.

SUMMARY OF THE DISCLOSED TECHNOLOGY [06] Disclosed herein is a system for supplying power including a speed multiplier, an electric generator, a transformer, and a fluid power mechanism. The system produces output energy for supplying power to an external system and produces input energy for supplying power to the fluid power mechanism for self-propelling the system and reproducing the output energy.

[07] In some embodiments, the speed multiplier includes a low-speed shaft and a high-speed shaft. In one embodiment, the electric generator includes a first electric generator and a second electric generator. In other embodiments, the fluid power mechanism comprises a hydraulic power mechanism including a hydraulic motor, a hydraulic pump including an oil reservoir, and a fluid hose coupling the hydraulic motor to the hydraulic pump such that the fluid power mechanism forms a closed circuit. In one embodiment, the speed multiplier includes a gearbox including the low-speed shaft and the high-speed shaft.

[08] In some embodiments, the low-speed shaft rotatable couples the speed multiplier to the hydraulic motor and the high-speed shaft rotatably couples the speed multiplier to the first electric generator and rotatably couples the speed multiplier to the second generator via a pulley and belt set. In one embodiment, the high-speed shaft includes a smaller diameter than the low- speed shaft.

[09] In some embodiments, the first electric generator is coupled to the transformer and the transformer is coupled to the hydraulic pump. In embodiments, the hydraulic pump is an Oleo hydraulic unit and/or Oleo hydrualic pump.

[010] In some embodiments, the system is initially set in motion by an initial input energy from a power source external to the system. In one embodiment, the system is initially set in motion after the initial input energy is supplied to the hydraulic pump, thereby activating the hydraulic pump to drive pressurized oil to the hydraulic motor via the fluid hose.

[O i l] In some embodiments, the hydraulic motor is driven by a fluid pressure of the pressurized oil. In one embodiment, the surface area of the hydraulic motor that receives the fluid pressure is greater than the surface area of the fluid hose, thereby generating a force multiplication that rotates the low-speed shaft at a first rotational velocity that actuates the speed multiplier. Actuation of the speed multiplier rotates the high-speed shaft at a second rotational velocity that is greater than the first rotational velocity. In one embodiment, the second rotational velocity is converted into the input energy in the form of electricity by the first electric generator and into the output energy in the form of electricity by the second electric generator. The input energy transfers through the transformer to the hydraulic pump, so as to transfer energy back into the system to self-propel the hydraulic pump and keep the system in motion, thereby reproducing the output energy.

[012] In other embodiments, the fluid power mechanism comprises a pneumatic power mechanism including a pneumatic motor, an air compressor including an air tank, and air pump, and an electric motor, and a fluid hose coupling the air tank to the pneumatic motor such that the fluid power mechanism forms a closed circuit.

[013] In some embodiments, the low-speed shaft couples the speed multiplier to the pneumatic motor. In one embdiment, the high-speed shaft rotatably couples the speed multiplier to the first electric generator and rotatably couples the speed multiplier to the second generator via a pulley and belt set.

[014] In some embodiments, the system is initially set in motion after the initial input energy is supplied to the electric motor, thereby activating the air pump to drive pressurized air formed in the air tank to the pneumatic motor via the fluid hose. [015] In some embodiments, the pneumatic motor is driven by a fluid pressure of the pressurized air. In one embodiment, the surface area of the pneumatic motor that receives the fluid pressure is greater than the surface area of the fluid hose, thereby generating a force multiplication that rotates the low-speed shaft at a first rotational velocity that actuates the speed multiplier. Actuation of the speed multiplier rotates the high-speed shaft at a second rotational velocity that is greater than the first rotational velocity. In one embodiment, the second rotational velocity is converted into the input energy in the form of electricity by the first electric generator and into the output energy in the form of electricity by the second electric generator. The input energy transfers through the transformer to the electric motor, so as to transfer energy back into the system to self-propel the air compressor and keep the system in motion, thereby reproducing the output energy.

[016 ] For purposes of this disclosure, the following definitions are used. “Oleo hydraulic unit” used interchangeably with“Oleo hydraulic pump” refers to a hydraulic pump employing the Oleo hydraulic principle - that is, under impact, the plunger is forced into the cylinder displacing oil through the orifice, moving the separator piston and compressing the gas. The compressed gas acts on the oil through the separator piston to give recoil force to re-extend the unit after impact. The energy absorbed and dissipated is dependent on the closure velocity. When the plunger is forced into the cylinder rapidly, the oil displaced by the plunger has to pass through the orifice at very high velocity. This raises the pressure in the oil chamber to a level which optimizes the closure force of the unit. This optimization process ensures that the impact energy is absorbed evenly throughout the plunger travel and thus maintaining a level impact force. The majority of the impact energy is absorbed within the unit and the already low recoil force is damped by the reverse flow of oil, leaving very little energy (for purposes of this disclosure, less than 5%) and recoil force to be returned to the impacting vehicle. [017] “External” refers to situated or being outside something. “Actuate” refers to causing something to operate, move, rotate, or act in a particular way which involves a change in position, angle, or function. “Fluid” refers to a substance, such as a liquid or gas. “Accumulator” refers to a part where data, numbers, or information is stored. “Pascal Principle” or “Pascal’s Law” refers to hydraulics and states when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container. “Self-excite” or self- excitation refers to the process of generating a magnetic field by means of an electric current. “Speed multiplier” refers to a mechanical component which multiplies output speed, such as angular speed, under a constant transmission ratio.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE DISCLOSED TECHNOLOGY

[02 1] The present disclosed technology provides a self-propelled system for generating and supplying energy that efficiently, with an initial input energy to the system, produces output energy, such as electrical or mechanical energy, for external systems. The system produces more input energy that self-propels the system, thereby keeping it in motion and allowing it to reproduce output energy for widespread applications such as propelling any transportation means and powering an electric grid. In some embodiments, the external system is an electric traction motor. In other embodiments, the output energy is converted to mechanical energy for traction in any vehicle.

[022] Embodiments of the disclosed technology will become clearer in view of the following description of the figures.

[023] The system includes a speed multiplier, one or more electric generators, a transformer, and a fluid power mechanism. In embodiments, the fluid power mechanism is a hydraulic power mechanism. In other embodiments, the fluid power mechanism is a pneumatic power mechanism. In one embodiment, the hydraulic power mechanism comprises an Oleo hydraulic unit. The Oleo hydraulic unit includes a hydraulic pump, an oil reservoir, a hydraulic motor and one or more fluid hoses. The fluid hoses functionally connect the components of the Oleo hydraulic unit, such that the components form a closed circuit. In one embodiment, the pneumatic power mechanism includes an air compressor set, a pneumatic motor, and one or more fluid hoses functionally connecting the components of the pneumatic power mechanism, such that the components form a closed circuit.

[024] FIG. 1 shows a schematic view of the self-propelled system for generating and supplying energy according to one embodiment of the present disclosed technology. In one embodiment, the system comprises the hydraulic power mechanism and includes a hydraulic motor 1, a input low-speed shaft 2, a speed multiplier 3, an output high-speed shaft 4, a pulley and belt set 5, a first electric generator 6, a second electric generator 7, a transformer 8, and a hydraulic pump 9 with an oil reservoir. In one embodiment, the hydraulic motor 1 is a low speed, high torque hydrualic motor. In one embodiment, the system is initially set in motion using input power provided by a power source that is external to the system. In other embodiments, the system is initial set in motion by a self-excited generator that actuates the hydraulic pump 9.

[025] In one embodiment, the first or second generators 6, 7 comprise self- excited generators. The self-excited generators provide a magnetic field generated by its own output. The magnetism is stored in electromagnets within the generators. When the generator stops, the stored magnetism is used to restart the system. Thus, in this embodiment, one of the generators 6, 7 can be used to restart the system, as opposed to with a power source external to the system.

[026] In another embodiment, a battery including an accumulator could be placed between the transformer 8 and the hydraulic pump 9. This battery/ accumulator can be used to supply power to the fluid power mechanism, e.g., the hydraulic pump 9 or the pneumatic power mechanism, to start the system. Also, the battery/ accumulator can keep the memories of electronic devices, such as a wireless transceiver (smart phone), computing device (laptop, tablet, desktop, etc.) and the like when used to control the system.

[027] The hydraulic pump 9 transmits power to the hydraulic motor 1, pumping oil to and from the oil reservoir and the hydraulic motor 1 by way of the fluid hoses. In one embodiment, the hydraulic pump 9 is reciprocally coupled to the hydraulic motor 1 by way of the fluid hoses. The hydraulic motor 1 is a rotational actuator that transforms the hydraulic energy (or pressure) into rotational mechanical energy. In some embodiments, the hydraulic motor 1 is a low-speed, high torque hydraulic motor for use with heavy external systems in which heavy load needs to be moved or lifted at a low speed, in a constant ratio.

[028] A force multiplication of the system can be achieved by applying fluid pressure to the hydraulic motor 1, according to the Pascal Principle. Fluid pressure is transmitted to all parts of the closed circuit of the hydraulic power mechanism, making possible a great multiplication of the force. Fluid pressure is applied from the hydraulic pump 9 to the hydraulic motor 1 by way of the fluid hoses. If the size of the surface area where the hydraulic motor 1 receives the oil pressure is greater than the surface area of the fluid hoses, there will be a force multiplication. Thus, this allows the required or sufficient force to rotate both electric generators 6 and 7 from the hydraulic motor 1 through the speed multiplier 3.

[029] In embodiments, the speed multiplier 3 is coupled to the hydraulic motor 1 by way of a low-speed shaft 2. In one embodiment, the speed multiplier 3 is, for example, a gearbox with an input shaft 2 and an output shaft 4. In some embodiments, the input shaft 2 is a low-speed shaft and the output shaft 4 is a high-speed shaft. The diameter of the input low-speed shaft 2 is greater than the diameter of the output high-speed shaft 4. In alternative embodiments, the speed multiplier includes flanges for more than one generator can be used in place of a speed multiplier configured for one generator.

[030] In some embodiments, the first electric generator 6 is rotatably coupled to the speed multiplier 3 by way of the output high-speed shaft 4. The second electric generator 7 is further rotatably coupled to the speed multiplier 3 by way of the output high-speed shaft 4 and the pulley and belt set 5. The rotational velocity of the output high-speed shaft 4 is converted into electricity using the first or second generators 6, 7. In one embodiment, the first electric generator 6 generates electricity that is transferred back into the system to self- propel it and keep the hydraulic pump 9 in motion. In one embodiment, the second electric generator 7 generates electricity for supply as output energy to an external system. [03 1] In embodiments, the first electric generator 6 is coupled to the transformer 8 and the transformer 8 is coupled to the hydraulic pump 9. In one embodiment, the transformer 8 is disposed between the first electric generator 6 and the hydraulic pump 9, such that it can transfer an output voltage and / or a current from the first electric generator 6 to a voltage and / or a current required by the hydraulic pump 9 so as to power the hydraulic pump 9. The transformer 8 receive electricity produced by the first electric generator 6, so a to generate an electrical output used to power the hydraulic pump 9.

[032] The hydraulic power mechanism uses fluid (oil) to transmit hydraulic power, produced by the hydraulic pump 9, to operate a mechanical apparatus. The hydraulic pump 9 injects fluid from the oil reservoir through the fluid hoses to the hydraulic motor 1, thereby self-propelling the system and keeping it in motion.

[033] In operation of some embodiments of the disclosed technology, the hydraulic pump 9 is initially set in motion by way of an external power source. The hydraulic pump 9 exchanges fluid between the oil reservoir and the hydraulic motor 1 by way of hoses. The oil pressure makes the hydraulic motor rotate. The hydraulic motor 1 rotates the input low-speed shaft 2 which is the input for the speed multiplier 3. The output high-speed shaft 4 includes a higher rotational velocity than the input low-speed shaft 2. The rotational velocity of the output high-speed shaft 4 is converted into electricity using the first and/or second electric generators 6, 7. The first generator 6 generates input electricity for supply back to the system in order to keep in motion. The second generator 7 generates output electricity for supply to an external system. The input electricity from the first generator 6 is transferred through the transformer 8 to the hydraulic pump 9, which power and drives the hydraulic pump 9. The hydraulic pump 9 then pumps pressurized oil to the hydraulic motor 1 to promote movement of the system. Thus, the whole system remains in motion. In one embodiment, the system includes a refrigeration system for the oil and other components is needed.

[034] FIG. 2 shows a schematic view of the self-propelled system for generating and supplying energy according to another embodiment of the present disclosed technology. In one embodiment, the fluid power mechanism comprises a pneumatic power mechanism comprising a pneumatic motor 10, an air-compressor set 1 1 including an air tank, an electric motor, and an air pump, and one or more fluid hoses functionally connecting the components of the pneumatic power mechanism to form a closed pneumatic circuit. In one embodiment, the pneumatic motor 10 includes a low speed, high torque pneumatic motor. The pneumatic power mechanism operates in a similar manner as the hydraulic power mechanism, except that the pneumatic power mechanism uses air instead of oil. The electric motor and the air pump are used for pumping compressed air inside the tank. The compressed air from the tank causes the pneumatic motor 10 to produce rotational mechanical movement keeping the system in motion. In one embodiment, lubricant can be used to decrease friction produced in the pneumatic power mechanism.

[035] In operation, the electric motor is initially driven by way of an external power source. The air pump drives pressurized air formed in the air tank to the pneumatic motor 10 via the fluid hoses. The air pressure actuates the pneumatic motor 10. The pneumatic motor 10 rotates the input low-speed shaft 2 of speed multiplier 3, which in turn rotates the output high-speed shaft 4 at a higher rotational velocity than the input low-speed shaft 2. The rotational velocity of the output high-speed shaft 4 is converted into electricity using the first and/or second electric generators 6, 7. The first generator 6 generates input electricity for supply back to the system in order to keep in motion. The second generator 7 generates output electricity for supply to an external system. The input electricity from the first generator 6 is transferred through the transformer 8 to the electric motor, which power and drives the air pump. The air pump then pumps pressurized air to the pneumatic motor 10 to promote movement of the system. Thus, the whole system remains in motion.
