    [0001] [001] This application is based on and claims priority for U.S. Provisional Application No. 61 / 731,682, filed on November 30, 2012, the description of which is incorporated herein by reference in its entirety. Field of the Invention
    [0002] [002] The present invention generally relates to work vehicles and, more particularly, to an inlet duct for an air inlet system for a work vehicle with a rain deflector configured to reduce the amount of water that enters the air intake system. Fundamentals of the Invention
    [0003] [003] Work vehicles typically include internal combustion engines that require clean air for use within the combustion process. Since many work vehicles, such as tractors and other agricultural vehicles, operate in fields and other harvesting environments in which the ambient air contains large amounts of dust, plant material and other particulate materials, an inlet system with a filter assembly effective is required. For example, conventional work vehicle filter sets typically include a vortex pre-cleaner or cyclone configured to separate large particulate materials from the inlet air and a porous air filter downstream of the air cleaner to provide the stage final filtration before delivering the air to the engine.
    [0004] [004] A work vehicle's air intake system may also include an intake duct that extends horizontally and / or vertically from the filter assembly to a location adjacent to the vehicle cabin. To allow a sufficient amount of air to enter the inlet duct, a relatively large opening in the upper end of the duct must be defined. Unfortunately, such a large opening increases the likelihood that debris and / or water (for example, rainwater) can enter the inlet duct and flow into the filter assembly, which can significantly shorten the life of the air filter. To address this problem at least partially, a screen is typically placed over the opening to protect the inlet duct from large debris. However, the screen is unable to prevent water from entering the inlet duct and flowing into the filter assembly.
    [0005] [005] Consequently, an inlet duct for an air intake system with a rain deflector configured to reduce the amount of water flowing into the system would be welcome in technology. Summary of the Invention
    [0006] [006] The aspects and advantages of the invention will be presented in part in the following description, or they can be obvious from the description, or they can be learned through the practice of the invention.
    [0007] [007] In one aspect, the present invention is directed to an inlet duct for a work vehicle air inlet system. The inlet duct can generally include a body that defines an air passage extending between an inlet end and an outlet end. The body may further define a recessed entry at the entry end including a first side section and a second side section. Each of the first side section and the second side section can define at least one side opening to direct the air to the air passage. In addition, the recessed entry may include a deflector that projects outwardly from the first and second side sections. The deflector can be configured to protect the air passage from the water directed to the lowered inlet.
    [0008] [008] In another aspect, the present invention is directed to an air intake system for a work vehicle. The air inlet system can generally include an inlet duct that defines an air passage that extends between an inlet end and an outlet end. The inlet duct can further define a recessed inlet at the inlet end that includes a first side section and a second side section. Each one of the first inlet section and the second side section defining at least one side opening to direct the air to the air passage. The lowered entrance can also include a deflector projecting externally from the first and the second side section. The deflector can be configured to protect the air passage from the water directed to the lowered inlet. In addition, the air inlet system may include a filter assembly in flow communication with the outlet end of the inlet duct. The filter set can be configured to filter the air received inside the inlet duct.
    [0009] [009] These and other characteristics, aspects and advantages of the present invention will become clearer with respect to the following description and the attached drawings. The attached drawings, which are incorporated and form part of that specification, illustrate the modalities of the invention and, together with the description, serve to explain the principles of the invention.

    [0017] [017] Reference will now be made in detail to the modalities of the invention, where one or more examples are illustrated in the drawings. Each example is provided by way of explanation of the invention, without limitation. In fact, it will be clear to those skilled in the art that various modifications and variations can be made to the present invention without abandoning the scope or spirit of the invention. For example, the features illustrated or described as part of one embodiment can be used with another embodiment to further produce an additional embodiment. Thus, it is intended that the present invention encompasses such modifications and variations as within the scope of the appended claims and their equivalents.
    [0018] [018] In general, the present invention is directed to an inlet duct for a work vehicle air inlet system. In various embodiments, the inlet duct may include a lowered inlet defining several openings configured to receive air from the external environment. In addition, the lowered inlet may include a rain deflector configured to divert water away from one or more openings, thereby reducing the amount of water entering the inlet duct.
    [0019] [019] With reference now to the drawings, FIG. 1 illustrates a side view of an embodiment of a working vehicle 10. As shown, working vehicle 10 is configured as an agricultural tractor. However, in other embodiments, the working vehicle 10 can be configured like any other suitable working vehicle known in the art, such as several other agricultural vehicles, earthmoving vehicles, road vehicles, all-terrain vehicles, off-road vehicles , loaders and the like.
    [0020] [020] As shown in FIG. 1, the work vehicle 10 includes a pair of front wheels 12, a pair of rear wheels 14 and a chassis 16 coupled and supported by wheels 12, 14. An operator's cabin 18 can be supported by part of the chassis 16 and can house various control devices 20 (for example, levers, pedals, control panels and / or the like) to allow an operator to control the operation of the work vehicle 10. Additionally, the work vehicle 10 can include an engine 22 and a transmission 24 mounted on chassis 16. Transmission 24 can be functionally coupled to engine 22 and can provide variable gear ratios to transfer power from the engine to the wheels 14 via a differential 26. Engine 22, transmission 24 and one differential 26 can collectively define a drive assembly 28 of the working vehicle 10.
    [0021] [021] With reference now to FIG. 2, a perspective view of an embodiment of an air intake system 30 suitable for use with the working vehicle 10 shown in FIG. 1 illustrated in accordance with aspects of the present invention. As shown in FIG. 2, the air inlet system 30 can generally include an inlet duct 32 and a filter assembly 34 in flow communication with the inlet duct 32. The inlet duct 32 can generally be configured to receive dirty flowing air outside the working vehicle 10 and directing such dirty air to the filter assembly 34 for cleaning / filtering before delivering the clean air to the engine 22. Thus, in various embodiments, the inlet duct 32 can generally comprise an elongated duct-like body defining one or more openings (not shown) to receive air. Additionally, as shown in FIG. 2, the screen 37 can be arranged over the openings, thus preventing large debris from entering the inlet duct 32. As will be described below with reference to FIGS. 3 to 7, the inlet duct 32 can also include an integrated rain deflector configured to reduce the amount of water entering the inlet duct 32 via the openings.
    [0022] [022] The filter set 34 of the air inlet system 30 can generally be configured to receive the dirty air from the inlet duct 32 and clean / filter it for subsequent delivery to the engine 22. Thus, in several embodiments, the filter assembly 34 may include a precleaner 38 and an air filter 40 disposed downstream of said precleaner 38. In addition, the filter assembly 34 may include a housing of the precleaner 42 configured to wrap the precleaner 38 and a filter housing 44 configured to surround said air filter 40. It should be appreciated that the housing of the precleaner 42 and the filter housing 44 can be formed integrally with each other ( for example, forming both housings 42, 44 as a single continuous housing) or the precleaner housing 42 and filter housing 44 may comprise separate components configured to be separately coupled to each other.
    [0023] [023] As shown in FIG. 2, in various embodiments, the precleaner housing 42 and the filter housing 44 can generally be oriented perpendicular to each other in such a way that the filter assembly 34 generally defines an "L" shape. As such, air flowing into the inlet duct 32 can be directed generally vertically downward through the precleaner 38 and then generally horizontally through the air filter 40. However, in other embodiments, the precleaner housing 42 and the filter housing 44 may have any other suitable orientation with respect to each other. For example, in another embodiment, the precleaner housing 42 and the filter housing 44 can be aligned along a common axis, such that air flowing through the filter assembly 34 is continuously directed along such a axis. axle.
    [0024] [024] As is generally understood, the precleaner 38 can be configured to remove large debris contained within the air flowing to the filter assembly 34 via the inlet duct 32. Specifically, in various modalities, the precleaner 38 may include various tubes (e.g., turbo tubes), dirt separators, and / or any other suitable pre-cleaner elements 46 configured to separate particulate matter from the air via centripetal force. For example, the pre-cleaner elements 46 can be configured to give a vortex or a rotary movement to the air flow entering the filter assembly 34. As a result, large particulate matter contained within the air can be forced radially externally to the along the inner wall of the precleaner 42 housing by the centripetal force of the vortex / turning motion. These large particulate matter can then be expelled from the filter assembly 34 via an outlet port (not shown) defined in the precleaner housing 42.
    [0025] [025] Additionally, the air filter 40 can generally be configured to receive the clean air flowing from the pre-cleaner 38 and filter such air to provide a final stage of filtration before delivering the air to the engine 22. Thus, as shown in FIG. 2, the air filter 40 may generally include including one or more filter elements 48 configured to catch or capture the remaining particulate matter contained within the clean air. For example, in various embodiments, the filtering element (s) 48 may be made of screen material, porous or fibrous which allows air to pass through them while catching / capturing any particulate matter. The clean / filtered air can then be directed through a duct (not shown) to the engine 22, where the air can be mixed with the fuel and subjected to combustion.
    [0026] [026] With reference now to FIGs. 3 to 7, several views of an embodiment of the inlet duct 32 shown in FIG. 2 are illustrated in accordance with aspects of the present invention. Specifically, FIG. 3 illustrates a partial side perspective view of the inlet duct 32 that has the screen 37 installed in the duct 32. FIG. 4 illustrates a partial side perspective view of the inlet duct 32 shown in FIG. 3 with the screen 37 being blown away from the duct 32. FIG. 5 illustrates a partial front perspective view of the inlet duct shown in FIG. 4. In addition, FIGs. 6 and 7 illustrate the cross-sectional views of the inlet duct 32 shown in FIG. 3 taken around lines 6-6 and 7-7, respectively.
    [0027] [027] In general, the inlet duct 32 can generally comprise an elongated body 100 defining an air passage 102 (shown in FIGS. 6 and 7) extending between an end of the inlet 104, where air is directed to the air passage 102, and an outlet end 106, where air flowing through the air passage 102 is directed to the filter assembly 34 (FIG. 2). In addition, in various embodiments, a body part 100 at the inlet end 104 can be lowered to define a lowered inlet 108. For example, as shown in FIGs. 4 and 5, the inlet duct 32 may include an outer edge 110 from which a part of the body 100 extends internally in relation to the rest of the body 100, thus forming the recessed entrance 108. Thus, one should appreciate that the outer edge 110 can generally define the outer perimeter of the recessed entrance 108, such that the recessed entrance 108 corresponds to the part of the body 100 that is recessed with respect to the outer edge 110. For example, as shown in FIGS. 4 and 5, the outer edge 110 generally extends along a top 114 and a base 116 of the recessed entrance 108, as well as a first side 118 and a second side 120 of the recessed entrance 108.
    [0028] [028] It should be appreciated that the screen 37 of the air inlet system 30 can, in various modalities, be configured to be coupled to the body 100 around the outer edge 110, in such a way as to extend over and cover the lowered entrance 108. For example, as shown in FIG. 4, the screen 37 can be configured to define a curved or semi-curved shape (for example, in the form of a "U") generally corresponding to the shape of the body 100 such that, when the screen 37 is coupled to said body 100 along the edge external 100, said screen 37 can generally form an extension of the non-recessed part of the body 100 (for example, defining a flush interface with the body 100). However, in other modalities, the screen 37 can define any other suitable form. Furthermore, the screen 37 can be configured as a single continuous screen or as multiple screens configured to cover the recessed entrance 108.
    [0029] [029] Additionally, it should be appreciated that the screen 37 can be configured to be coupled to the body 100 using any suitable connection device known in the art. For example, as shown in FIG. 4, in one embodiment, several fastener openings 122 can be defined at the outer edge 110 along the first and second side 118, 120 of the recessed entrance 108, which are configured to receive the appropriate mechanical fasteners 124 (e.g. screws, pins and / or similar) to attach the screen 37 to the body 100. In other embodiments, the screen 37 can be configured to be attached to the body 100 along the outer edge 110 and / or fixed to the body 100 using any other device connection point.
    [0030] [030] In various embodiments, the recessed opening 108 may include a first side section 126 and a second side section 128 that project internally from the outer edge 110, with each side section 126, 128 defining one or more side openings 130 configured to direct the air that passes through the screen 37 into the air passage 102. For example, as shown in FIGs. 5 and 7, the first side section 126 can project internally from the outer edge 110 along the first side 118 of the recessed entrance 118 such that the first side section 126 is generally on a plane (for example, a vertical plane ) that extends between the top 114 and the base 116 of the lowered entrance 108. Similarly, the second side section 130 can project internally from the outer edge 110 along the second side 120 of the lowered entrance 108, such that the second side section 128 is generally on a plane (for example, a vertical plane) that extends between the top 114 and the base 116 of the lowered entrance 108. In such an embodiment, the first and second side section 126, 128 may, for example, example, be oriented parallel to each other and can be arranged within the same or different planes. Alternatively, the first and second side section 126, 128 can define a non-planar orientation between the top 114 and the base 116 of the recessed entrance 108.
    [0031] [031] It should be appreciated that the number of side openings 130 can be defined in the first and second sections 126, 128 of the lowered entrance 108. For example, as shown in FIG. 5, four side openings are defined in each side section 126, 128. However, in other embodiments, the first and second side section 126, 128 can define less than four side openings 130 or more than four side openings 130. It would also appreciate that the recessed entrance 108 can also define other openings around its periphery to direct the air to the air passage 102. For example, as shown in FIG. 5, an opening 156 (e.g., a "U" shaped opening) can be defined at the top of the recessed entrance 108.
    [0032] [032] Additionally, in accordance with aspects of the present invention, the recessed inlet 108 may also include a rain deflector 132 that is externally protected from the first and second side sections 126, 128. In general, deflector 132 can be configured to serve as a water protection to reduce the amount of water entering the air passage 102. For example, as particularly shown in FIG. 6, the water (indicated by arrows 134), which passes through the screen 37, can come in contact with the deflector 132 and be deflected / flow downwards along the deflector 132. The water can then flow back through the screen 37 at the base 116 of the lowered entrance 108. For example, as shown in FIG. 5, the base 116 of the recessed entrance 108 can be angled downwardly from the deflector 132 towards the outer edge 110, such that the water that falls on the base 116 can be directed outwards towards the screen 37.
    [0033] [033] In various embodiments, the deflector 132 can be configured to project externally from the first and second side sections 126, 128, so that at least part of the deflector 132 is positioned closer to a central or central point. apex 136 of the screen 37 than the side sections 126, 128. For example, as shown in FIG. 7, the deflector 132 can project externally from the first and the second side section 126, 128 in the direction of the screen 37, in order to define a partially curved shape, or “U” shape, with the apex point 138 of the said deflector 132 being generally aligned with the apex point 136 of the screen 37. In such an embodiment, since the front part of the screen 37 (centered around the apex point 136) is positioned closer to the deflector 132 than to the side sections 126, 128, the water directed through said front part of the screen 37 may be more likely to come into contact with the deflector 132, thus reducing the amount of water that enters the air passage 102 through the side openings 130.
    [0034] [034] In addition, in various embodiments, the deflector 132 can define one or more deflector openings 140, 142, 144 configured to direct the air that passes through the screen 37 into the air passage 102. In such embodiments, the openings of the baffle 140, 142, 144 can generally be positioned and / or oriented along the baffle 132 in a way that prevents a significant amount of water from being directed to said openings 140, 142, 144. For example, as shown in FIGs . 4 and 5, in one embodiment, an upper deflector opening 140 can be defined at the top of said deflector 132. Such opening 140 can generally be protected from water by the top of the inlet duct 32 and the screen 37. For example, even in windy storms, in which rainwater is being directed almost horizontally, the screen 37 can sufficiently reduce the speed of the water, such that, given the lowered position of the upper opening of the deflector 140 in relation to the screen 37, the water will fall below opening 140 and will come in contact with the bottom of deflector 132.
    [0035] [035] Additionally, one or more openings of the baffle 140, 142 can also be defined between the separate parts of the baffle 132. For example, as shown in FIG. 5, in one embodiment, the baffle 132 may be partially separated or divided along its length into several baffle parts (for example, a first baffle part 146, a second baffle part 148 and a third baffle part 150) , each baffle part 146, 148, 150 extending vertically between an upper edge 152 and a lower edge 154. In such an embodiment, the baffle parts 146, 148 can be widened with respect to the lower baffle parts 148, 150 , such that the baffle openings 142, 144 are defined between adjacent baffle parts 146, 148, 150. For example, as shown in FIGS. 4 to 6, the first baffle part 146 can be enlarged externally at its lower edge 154 with respect to the top edge 152 of the second baffle part 148, so that a first baffle opening 142 is defined between the first and the second part deflector 146, 148. Similarly, the second deflector part 148 can be enlarged externally at its lower edge 154 with respect to the upper edge 152 of the third deflector part 150 so that a second deflector opening 144 is defined between the second and the third baffle part 148, 150.
    [0036] [036] By configuring the baffle parts 146, 148, 150 as described above, the first and second baffle openings 142, 144 can be protected from water by baffle 132. Specifically, by extending the first and second baffle parts 146, 148 at its lower edges 154, water flowing down along the baffle 132 can be directed away from the baffle openings 142, 144. For example, as shown in FIG. 6, water 134 flowing along the baffle 132 may fall or flow down the lower edges 154 of the first and second baffle parts 146, 148 without entering the first and second baffle openings 142, 144. However, the air flowing through the screen (indicated by arrows 158 in FIG. 6) can be directed between adjacent edges 152, 154 of the deflection parts 146, 148, 150 and into the air passage 102.
    [0037] [037] Additionally, the relative positioning of the top and bottom edges 152, 154 of the adjacent baffle parts 146, 148, 150 can be selected to further prevent water from entering the first and second baffle openings 142, 144. For example, as shown in FIG. 6, in one embodiment, the lower edges 154 of the first and second baffle parts 146, 148 can be horizontally aligned with the upper edges 152 of the second and third baffle parts 148, 150, respectively. Alternatively, the baffle parts 146, 148, 150 can be configured to overlap slightly, so that the lower edges 154 of the first and second baffle parts 146, 148 extend vertically below the upper edges 152 of the second and third baffle part 148, 150, respectively.
    [0038] [038] It should be appreciated that, in order to prevent water from flowing around the lower edges 154 of the upper baffle parts 146, 148 and being sucked into the first and second baffle openings 142, 144, each lower edge 154 it can, in one embodiment, be configured to define a non-rounded shape so that any water flowing along the upper parts of the baffle 146, 148 actually flows from the lower edges 154. For example, FIG. 6 illustrates two examples of suitable non-rounded shapes. As shown, the bottom edge 154 of the first baffle part 142 defines a square edge with 90 degree corners while the bottom edge 154 of the second baffle part 148 defines a sharp tapering edge to a point. However, in other embodiments, the lower edges 154 can define any other suitable shape.
    [0039] [039] Additionally, it should be appreciated that while the illustrated embodiment shows deflector 132 including three deflector parts 146, 148, 150 with two deflector openings 142, 144 being defined between each pair of adjacent deflector parts, baffle 132 can generally be configured to include any number of baffle parts by defining any number of baffle openings between them.
    [0040] [040] Furthermore, it should be appreciated that, in various embodiments, the body 100 of the inlet duct 32 can generally be formed as a single molded component. Thus, deflector 132 can be formed integrally with side sections 126, 128 and the remainder of body 100. However, in an alternative embodiment, deflector 132 can be configured to be separately coupled within the recessed entrance 108.

The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art.
