The following specification particularly describes the invention and the manner in which it
is to be performed.

FIELDOFDISCLOSURE [0001] The present disclosure relates to a fluid driven power generating apparatus for a vehicle, and more particularly, relates to the fluid driven power generating apparatus for generating power using wind energy for all types of vehicles.
BACKGROUND
[0002] Conventional vehicles use petroleum fuels such as gasoline and diesel, or coal products, which are burned to drive an engine of a vehicle. This significantly contributes to air pollution andgeneration of greenhouse gases, such as carbon dioxide. This air pollution is harmful to the health of living creatures and may cause global warming. Petroleum or fossil fuels are not renewable resources.
[0003] Due to the recent developments in vehicular technology, the vehicle engines are now powered by electric batteries. However, there is a major drawback with these electric battery operated vehicles. The electric battery operated vehicles need to be plugged-in at a charging station for a particular time period to charge the electric batteries that power the vehicle engines. Though the electric battery operated vehicles are becoming popular, the infrastructure for facilitating charging of the electric batteries is yet to be developed.
[0004] Further developments in this area demonstrate the use of renewable energy to charge the electric batteries of the vehicles. Systems are known that produce energy from fluids in motion, such as wind. A rotary mechanism is employed for collection of energy from wind in motion. The energy is translated into electricity that is used to charge the batteries. However, there are many disadvantages associated with transporting, storing, and distributing the electricity. Further, such systems increase the cost and complexity of the overall vehicular systems.
[0005] The present disclosure is directed to alleviate one or more limitations stated above or any other limitations associated with the conventional systems.

DETAILED DESCRIPTION
[0031] The foregoing has broadly outlined the features and technical advantages of the present disclosure in order that the detailed description of the disclosure that follows may be better understood. Additional features and advantages of the

disclosure will be described hereinafter which form the subject of the description of the disclosure. It should also be realized by those skilled in the art that such equivalent methods do not depart from the scope of the disclosure. The novel features which are believed to be characteristic of the disclosure, as to assembly of components, together with further objects and advantages will be better understood from the following description when considered in connection with the accompanying figures. It is to be expressly understood, however, that each of the figures is provided for the purpose of illustration and description only and is not intended as a definition of the limits of the present disclosure.
[0032] In the present document, the word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any embodiment or implementation of the present subject matter described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.
[0033] While the disclosure is susceptible to various modifications and alternative forms, specific embodiment thereof has been shown by way of example in the drawings and will be described in detail below. It should be understood, however that it is not intended to limit the disclosure to the particular forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternative falling within the scope of the disclosure.
[0034] The terms “comprises”, “comprising”, or any other variations thereof used in the specification, are intended to cover a non-exclusive inclusion, such that an apparatus that comprises a list of components or steps does not include only those components or steps but may include other components or steps not expressly listed or inherent to such setup or method. In other words, one or more elements in an

apparatus proceeded by “comprises… a” does not, without more constraints, preclude the existence of other elements or additional elements in the apparatus.
[0035] In order to overcome the limitations stated in the background, the present disclosure provides the following paragraphs which describe the present disclosure with reference to FIG. 1 and 2. In the figures, the same element or elements which have same functions are indicated by the same reference signs. One skilled in the art would appreciate that the a fluid driven power generating apparatus of the present disclosure may be employed in any vehicle including but not limiting to a two wheeled vehicle, a three wheeled vehicle, a four wheeled vehicle, and the like.
[0036] Embodiments of the present disclosure disclose an a fluid driven power generating apparatus for a vehicle. Generally, vehicles use petroleum fuels, which when burned to propel the vehicle, emit air pollution or greenhouse gases. Further, engines of some of the vehicles are made to be completely electric, but there is a major drawback with these: they need to be plugged in for a while to charge electric batteries that power the electric engine. The efforts have been taken to develop systems that facilitate charging of the electric batteries of the vehicles with the use of renewable energy. However, transporting, storing, and distributing the electricity in such systems are complex tasks and involve additional cost.
[0037] The fluid driven power generating apparatus of the present disclosure may be employed in any type of vehicles. The apparatus includes a turbine, which allows fluid entering from its opening to swirl and rotate the turbine. The rotation of the turbine generates energy which is then transferred by an energy transfer mechanism to a storing device for storing purpose. The energy transfer mechanism may employ rolling friction gears. The storing device may be a mechanical device, such as a flywheel, which stores the energy with a cumulative factor. The apparatus also includes a transmission unit for transmitting the stored energy from the storing device

to the output. The transmission mechanism may be a mechanical Continuously Variable Transmission that propels driving wheels of the vehicle.
[0038] In an embodiment, adapting the apparatus of the present disclosure may provide effective utilization of the renewable energy to propel the vehicle, and thus, provides efficient and cost effective way of commute to passengers.
[0039] In the following detailed description, embodiments of the disclosure are explained with reference of accompanying figures that form a part thereof, and in which are shown by way of illustration specific embodiments in which the disclosure may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the disclosure, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present disclosure. The following description is, therefore, not to be taken in a limiting sense.
[0040] In an embodiment of the present disclosure, perspective front and back views of a fluid driven power generating apparatus 100 are disclosed in FIG. 1 and FIG. 2, respectively. The apparatus 100 comprises a turbine 102, an energy transfer mechanism 104, a storing device 106, a transmission unit 108, and an output 110.
[0041] The turbine 102 with a fixed foundation base may preferably be located and installed onto a part of a vehicle, where relatively high wind speed can be observed during a running condition of the vehicle. This might be on a roof of a vehicle, on a front bonnet of a vehicle, or other part of the vehicle that observes unobstructed flow of strong wind currents. The turbine 102 may be made up of a rotating shaft 112 and one or more vanes 116 that rotationally drive the rotating shaft 112. Bottom portions of the one or more vanes 116 may be connected to the rotating shaft 112. Top portions of the one or more vanes 116 may be tilted spirally in a single rotational direction along around the rotating shaft 112. The rotational direction of the tilting

may either be a clockwise direction or be an anti-clockwise direction. A region encompassed by the one or more vanes 116 may form a cavity. The cavity at a back end portion of the turbine 102 may form a venting hole, while the cavity at a front end portion of the turbine 102 may form an opening. The opening at the front end portion may have a broader diameter than the venting hole, which may allow fluid entering from the opening to swirl and pass through the venting hole. The passing fluid may generate rotational driving force centering on the rotating shaft 102.
[0042] The turbines are known to work either on a lift effect of the wind (as seen in horizontal axis wind turbines) or on a drag effect of the wind (as seen in vertical axis wind turbines). However, the turbine 102 of the present disclosure may harness both the lift effect of the wind and the drag effect of the wind. A streamlined design of the turbine 102 causes the wind to move freely through the cavity, thereby creating the drag effect, whereas the swirling of the wind through the cavity creates the lift effect. Further, an opening angle of the turbine plays a key role in deciding the efficiency of the turbine. Generally, the turbines with the opening angles of 30° and 60° are known. In an example implementation of the present disclosure, the turbine 102 with the opening angles ranging from 55° to 59° may be designed to harness the wind with better efficiency. In the best mode of implementation of the present disclosure, the opening angle of 57.71° may be designed to yield maximum efficiency of the turbine 102. In an example, the turbine 102 of the present disclosure may capture the naturally blowing wind at a minimum speed of 10 km per hour.
[0043] Further, the energy transfer mechanism 104 may be coupled at the back end portion of the turbine 102 for receiving the angular kinetic energy generated by the turbine 102. The energy transfer mechanism 104 may comprise a rotatable input shaft 202 and a rotatable output shaft 204, coupled together by rolling friction gears 206. The rotatable input shaft 202 may be coupled to the rotating shaft 112 of the turbine 102. The rotatable input shaft 202 of the energy transfer mechanism 104 may have a

plurality of teeth formed on its perimeter. These teeth may mesh with teeth of a the rolling friction gears 206 to rotate the gears, and in turn the rotatable output shaft 204, at speeds equal to the speeds of rotation of the rotatable input shaft 202. In an example implementation, the rolling friction gears 206 may be employed as at least one of spur gears, helical gears, bevel gears, a rack and pinion gears, or a combination thereof.
[0044] The energy transfer mechanism 104 of the present disclosure is advantageous as it employs the rolling friction gears 206, instead of sliding friction gears. The conventionally used sliding friction gears have eight points of sliding friction contact points. The rolling friction gears eliminate these contact points by employing rollers, thus adding to the efficiency of the energy transfer mechanism 104.
[0045] Furthermore, the storing device 106 may be employed to store the angular kinetic energy. For this, the energy transfer mechanism 104 may transfer the energy from the turbine 102 to the storing device 106. In an example implementation, a flywheel may be employed as the storing device 106. While the apparatus 100 may be sized and otherwise constructed to accommodate more than one flywheel rotating therein, in the preferred embodiment illustrated, a single flywheel is shown, as this is the simplest to illustrate and describe. The flywheel may include a rotor and a drive shaft connected to the rotatable output shaft 204 of the energy transfer mechanism 104. The rotor is cylindrical with its axis aligned with the drive shaft. The diameter of the drive shaft may differ due to the different loads applied. The rotor may be made from a material having ferromagnetic properties, such as, for example, high density steel. In alternate embodiments, other ferromagnetic materials from which the rotor may be manufactured are iron, nickel, cobalt, and the like.
[0046] In an example implementation, the flywheel may comprise a one way roller ramp clutch 208 so as to achieve energy balance. The one way roller ramp clutch 208 transfers a torque in one direction and move freely in an opposite direction. In

neutral, the one way roller ramp clutch 208 has a low frictional torque, which prevents the flywheel losses and saves energy.
[0047] The apparatus 100 also comprises the transmission unit 108 for transmitting the stored angular kinetic energy from the storing device 106 to the output 110. In a preferred embodiment of the present disclosure, the transmission unit 108 may comprise a Continuous Variable Transmission (CVT). The CVT may employ a mechanical control using a four bar chain mechanism. The four bar chain mechanism may further employ a flexible link, such as a wire or string, for changing gear ratios.
[0048] The four bar chain mechanism comprises four rigid links, one of which is a fixed link, while the other three are free to oscillate at joints. The four bar chain mechanism enables to-and-fro motion required to control the CVT. The four bar chain mechanism may be used in the form of a derailleur mechanism 114, to control the CVT.
[0049] The CVT may also comprise flexible pulleys in order to control gear ratios, the derailleur mechanism 114 is coupled to the flexible pulleys using a cable to enable the change in the gear ratios.
Equivalents
[0050] With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
[0051] It will be understood by those within the art that, in general, terms used herein, are generally intended as "open" terms (e.g., the term "including" should be interpreted as "including but not limited to," the term "having" should be interpreted

as "having at least," the term "includes" should be interpreted as "includes but is not limited to," etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding the description may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (e.g., "a" and/or "an" should typically be interpreted to mean "at least one" or "one or more"); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of "two recitations," without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to "at least one of A, B, and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, and C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to "at least one of A, B, or C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, or C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further

understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B".
[0052] While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope being indicated in the description.
TECHNICAL ADVANCEMENTS AND ECONOMIC SIGNIFICANCE [0053] The present apparatus offers solution to the existing problems by providing a fluid driven power generating apparatus that propels a vehicle without polluting air and emitting greenhouse gases. The apparatus also uses renewable fuel source for propelling a vehicle, thereby reducing dependency on fossil fuels. Furthermore, the apparatus provides a vehicle with reduced operating cost as compared to the cost of operating a vehicle powered by an internal-combustion engine that is fueled by fossil fuels. The fluid driven power generating apparatus of the present disclosure overcomes the cost and space requirements for building the infrastructure for facilitating charging of the electric vehicle batteries. The fluid driven power generating apparatus of the present disclosure is efficient, uncomplicated, and cost-effective.
