Description

Technical Field

[0001] The present invention generally relates to a work vehicle and, more particularly, to an air intake for a cooling system of a work vehicle. Background Art

[0002] Working vehicles including agricultural vehicles and construction vehicles are usually powered by internal combustion engines. Usually, these vehicles are used in dirty environments, and the air contains dust and other particulate matter. Agricultural vehicles also work in environments where there are crop residues and dust and particulate matter in the air. During operation, air is sucked into the frame of the vehicle and into the engine compartment for cooling the engine and providing effective combustion in the internal combustion engine. More particularly, the air supplied should be free of particulate matter. In harvesting / construction environments, this usually requires air filtration and / or cleaning systems so that the air sucked can be fully cleaned for engine combustion or cooling. Even with this filtration / cleaning system, particulate matter, dust and / or crop residues also can block or partially block the intake system, thereby causing the need to clean the system at frequent intervals.

[0003] In addition, to provide efficient combustion in the engine, air drawn into the vehicle from outside the frame provides cooling for a cooling system that is directed to one or more coolers, the cooling system including coolers to: i) cool the engine; ii) cool the hydraulic system; and iii) cool air directed to the engine's turbocharging system (if a turbocharging system is used). The air flow drawn from outside the frame is directed to an air filtration system and / or cleaning system before being directed to the coolers to ensure that the relatively clean air drawn through the coolers does not impede the air flow through the coolers. However, each cooler can and does provide a different amount of cooling to the system to which each cooler is connected. Therefore, the air flow drawn from the outside and directed to the coolers through the filtration system may not provide the amount of cooling required by one of the coolers. Therefore, there is a need for a system and method for varying the flow rate of air flow required by each cooler of a cooling system. Summary of the invention

[0004] In one embodiment, a work vehicle is provided, comprising a vehicle body having a top and a side and an internal combustion engine located in an engine compartment of the vehicle body. A cooling system includes a fan configured to direct an air flow. An inlet is disposed near the top of the vehicle body and faces in an upward direction, the inlet being configured to direct ambient air from outside the vehicle body to the cooling system. A shutter system is disposed adjacent to the inlet and located on a side of the vehicle body. The shutter system includes a plurality of slats and one or more actuators, wherein the one or more actuators are operably connected to the plurality of slats to adjust the angle of the slats relative to the side of the vehicle and provide a flow path for the air flow directed by the fan.

[0005] In another embodiment, a work vehicle is provided, comprising a vehicle body having a top and a side, and a cooling system having a plurality of stacked coolers and a fan disposed adjacent to the plurality of stacked coolers. The fan is configured to direct an air flow through the stacked coolers. An inlet is disposed near the top of the vehicle body and faces in an upward direction to direct ambient air from outside the vehicle body to the cooling system. A shutter system is disposed adjacent to the inlet and disposed on the side of the vehicle body, wherein the shutter system comprises a first actuator operably connected to a plurality of first slats and a second actuator operably connected to a plurality of second slats. A first sensor is operably connected to a first cooler of the plurality of stacked coolers, configured to identify a first temperature of the first cooler, and to generate a signal in response to the identified first temperature. A second sensor is operably connected to a second cooler of the plurality of stacked coolers, configured to identify a second temperature of the second cooler, and to generate a signal in response to the identified second temperature.

[0006] In another embodiment, a cooling system for a work vehicle is provided, the cooling system comprising a first cooler and a second cooler disposed adjacent to the first cooler. A fan is disposed adjacent to the first cooler and the second cooler and is configured to direct air flow to the first cooler and the second cooler. The shutter system comprises a plurality of slats and one or more actuators, wherein the one or more actuators are operably connected to the plurality of slats to adjust the angle of the slats to provide a flow path for the air flow directed by the fan.

[0014] In order to promote the understanding of the principles of the present invention, reference will now be made to the embodiments described herein and shown in the accompanying drawings, and specific language will be used to describe these embodiments. However, it should be understood that this is not meant to limit the scope of the present invention, and that changes and further improvements to the illustrated apparatus and methods, as well as further applications of the principles of the present invention described herein, will be apparent to those skilled in the art.

[0015] Referring now to the drawings and more particularly to Figure 1 , a work vehicle in the form of an agricultural harvesting machine such as an agricultural combine harvester 10 is shown. The work vehicle may also be in the form of different types of vehicles used in dirty or debris-filled operating environments. Such work vehicles include, but are not limited to, agricultural tractors, construction vehicles, forestry vehicles, lawn maintenance vehicles, and road vehicles, such as vehicles for snow removal, salt spreading, or vehicles with traction capabilities. In addition, the work vehicle includes other agricultural vehicles, such as a self-propelled combine harvester, which includes a prime mover that generates power to perform the work.

[0016] The combine harvester 10 includes a support structure or body 12 having ground engaging wheels 14 extending from the body 12. Although the combine harvester 10 is shown as having wheels 14, it may also have ground engaging tracks, either full tracks or half tracks. The combine harvester 12 also has a feeder house 16 through which harvested crop material is conveyed into the combine harvester 10 for processing. Once processed, the harvested crop material is stored in a grain box 18 in the combine harvester 10 and is unloaded from the combine harvester 10 by an unloading auger 20. The operation of the combine harvester 10 is controlled by an operator cab 22.

[0017] Mechanical power for the combine harvester 10 is provided by an internal combustion engine (not shown) housed in an engine compartment 24 at the rear of the combine harvester 12. A cooler stack 26 includes a radiator 28 (see FIG. 2 ) located in the engine compartment 24. Figure 2 and 3 ) for circulating cooling fluid through the internal combustion engine and other systems. The combine harvester 10 has a plurality of body panels surrounding the sides and rear of the combine harvester, including but not limited to: a rear panel 30, a left side panel (not shown), a right side panel 32, and a radiator door panel 34, the radiator door panel 34 is adjacent to the area of ​​the engine compartment 24 where the radiator 28 is located, and the radiator door panel 34 has an air scoop 40.

[0018] like Figure 2As shown, the cooling system includes a scoop 40 positioned adjacent to a filter 42, which is used to filter the ambient air sucked into the engine compartment 24. The filter 42 includes a panel with one or more filters. In other embodiments, the filter 42 is a rotating filter or a stationary rectangular filter. The filter described here is a rotating filter 42. The scoop 40 has an inlet 44 positioned above the engine compartment 24. Typically, the air laden with dust and debris stirred up by the equipment during operation rises to several feet above the ground level. By positioning the scoop inlet 44 above the height of the combine harvester 10 and by making the scoop inlet 44 face the upward direction, the air sucked into the engine is substantially cleaner. This in turn reduces the amount of impurities that must be screened and filtered from the incoming air by the rotating filter 42. In one or more embodiments, the rotating filter 42 is cleaned by a brush and / or vacuum system positioned adjacent to the filter.

[0019] The scoop 40 has a generally L-shaped flow path defined by an outer wall 46, which extends from the inlet 44 along the length of the outer wall 46 and extends to the front of the rotating screen 42. The L-shaped flow path directs the incoming air from a generally vertical downward direction to a generally horizontal direction, entering the rotating screen 42. The scoop 40 is positioned in association with the rotating screen 42 so that sufficient air flow flows through the rotating screen 44 and the cooler stack 26. The fan 48 draws air through the scoop 40, the rotating screen 42 and the cooler stack 26 into the engine compartment 24 where the engine 49 is located. In the illustrated embodiment, the scoop 40 has a generally U-shaped cross-section, approximating the width of the rotating screen 42. The curved transition in the outer wall 46 of the scoop 40 between the inlet 44 and the area of ​​the scoop 40 adjacent to the rotating screen 42 redirects air in a horizontal direction to the rotating screen 42 without significant restriction. The support frame 50 provides support for the rotating screen 42 and the cooler stack 26.

[0020] The air bucket 40 includes a louver 54 supported by the outer wall 46 of the air bucket 40. The louver 54 includes a plurality of slats 60 that are adjustable relative to the outer wall 46. The slats are arranged such as Figure 2 The scoop 40 is movable between a fully closed position and an open position, thereby varying the amount of air drawn through the cooler stack 26 by the fan 48. During operation, air is drawn through the scoop 40, including through the slats 60, through the rotating screen 42, and through the cooler stack 26, depending on the position of the slats. Since the scoop inlet 44 opens in an upward direction at or above the combine harvester 10, the air is substantially cleaner. The slats 60 are also located several feet above ground level, which is typically higher than the dust and debris laden air stirred up by the equipment during operation. Any dust and debris laden air flowing between the slats 60 is cleaned by the rotating screen 42.

[0021] Figure 3The wind scoop 40 is shown. Figure 2 Schematic diagram of the slats 60. The position of the rotating filter 42 is indicated by the dotted line. The cooler stack 26 includes a radiator 28, an oil cooler 62 located above the radiator 28, and a charge air cooler (CAC) 64 located above the oil cooler 62. Although each cooler of the cooler stack 28 is shown as being roughly aligned along a vertical plane, other positions of the coolers of the cooler stack 28 are also contemplated, either staggered or separated. Other embodiments in which the coolers are arranged in a different order from the bottom cooler to the top cooler can be contemplated. In other embodiments, additional or different coolers are included in the cooling system. For example, in one embodiment, an electronic cooler is included to provide cooling for electronic drives. Other configurations and positions of coolers can be contemplated.

[0022] In one embodiment, the position of the slats 60 can be adjusted as a slat group or slat array. In one embodiment, the slats are opened to allow more air to enter a specific portion of the cooler stack 26, such as a radiator, while closing the air flow to other coolers with less cooling requirements. In this way, the power requirements of the cooling fan can be reduced while focusing the air flow to the required cooling core. For example, if the vehicle's air conditioning is turned on, the slats corresponding to the air conditioning are opened to provide more air flow without the need to speed up the fan or change the blade pitch.

[0023] like Figure 3 As shown, the position of each slat 60 of the first slat group 66 is adjusted as a group so that each slat 60 can be positioned in the same orientation relative to the outer wall 46. Each slat of the first group 66 is connected to a lever 67 to move each slat simultaneously and to the same orientation, as will be understood by one of ordinary skill in the art. An air flow 68 through the first group 66 is shown. The air flow 66 is directed toward the CAC 64 by the slats of the first group 66. The slats 60 of the second group 70 are adjusted as a group so that each of the slats 60 of the second group 70 is positioned in the same orientation relative to the outer wall 46. The air flow 72 is directed toward the oil cooler 62 by the second group. The slats 60 of the third group 74 are adjusted as a group so that each slat 60 of the third group 74 is positioned in the same orientation relative to the outer wall 46. The air flow 76 is directed toward the oil cooler radiator 28 by the third group. Each of the groups 70 and 74 is moved by a lever, such as the lever 67, but not shown.

[0024] like Figure 4As shown, each of the slat groups 66, 70, and 74 is connected to an actuator, wherein the actuators include, but are not limited to, motors, hydraulic cylinders, and pneumatic devices. Group 66 is operably connected to actuator 80. Group 70 is operably connected to actuator 82. Group 74 is operably connected to actuator 84. Each actuator causes the slats of the corresponding group to move from a closed position to an open position to adjust the amount of air flow entering the cooling system. In one embodiment, the actuator is configured to move the grouped slats between two positions, an open position and a closed position. In another embodiment, the actuator is configured to move the slats to an orientation between the open position and the closed position. As shown in FIG. Figure 4 As shown, group 66 is in the open position, while groups 70 and 74 are in a position between the closed position and the open position. Depending on the amount of dust carried by the air and the cooling air flow required to dissipate the heat load experienced by the engine, oil cooling system and turbocharger system, the slats are fully closed to prevent clogging by dust. When moving from the closed position to the open position, the angle of the slats changes.

[0025] By adjusting the position of the slats or groups of slats, the vehicle continues to operate in a severe cloud of debris while avoiding filter plugging and radiator core plugging. Conversely, if debris conditions are favorable, the slats open to allow air to flow freely into the cooling system while the fan speed or the pitch angle of the fan is reduced to save parasitic engine power. This arrangement is useful, for example, during road transport when negligible airborne dust is present.

[0026] Multiple actuators enable each slat to be opened or closed independently. In various embodiments, one or more slats are closed at the bottom of the air intake scoop to minimize dust. The remaining slats located higher up are opened to maintain air flow while reducing dust from entering the cooling pack.

[0027] For parallel cooler stacks, the slats are opened to allow more air to enter a specific cooler in the cooling pack, such as a radiator, while closing other coolers with less cooling requirements. In this way, the power requirements of the cooling fan can be reduced while focusing the air flow to the required cooling core.

[0028] Each actuator 80, 82, and 84 is operably connected to a controller 90, which in one embodiment includes a memory configured to store program instructions and a processor device configured to execute the stored program instructions to adjust the position of the actuator. In other embodiments, the controller 90 is a distributed controller with separate independent controllers distributed at different locations on the vehicle 10. In addition, although the controller is typically hardwired to the relevant components by wires or cables, in other embodiments, the controller 90 includes a wireless transmitter and / or receiver to communicate with the controlled or sensed component or device, which provides information to the controller or transmits controller information to the controlled device.

[0029] In various embodiments, the controller 90 includes one or more microprocessors and associated memory, which may be internal to the processor or external to the processor. The memory may include a random access memory (RAM) device, which includes the memory storage device of the controller 90, and any other type of memory, such as cache memory, non-volatile or backup memory, programmable memory or flash memory, and read-only memory.

[0030] The controller 90 executes or otherwise relies on a computer software application, element, program, object, module or data structure. In response to the received signal, a software routine residing in a memory or other storage included in the controller 90 is executed. The executed software includes one or more specific applications, elements, programs, objects, modules or instruction sequences generally referred to as "program code". The program code includes one or more instructions located in the memory and other storage devices, and the storage device executes the instructions residing in the memory, which are provided in response to other instructions generated by the system or at a user interface operated by a user. The processor is configured to execute the stored program instructions and access data stored in one or more data tables.

[0031] One or more temperature sensors are configured to determine the temperature of the fluid moving through the radiator 28 or the temperature of the radiator itself, the temperature of the fluid moving through the oil cooler 62 or the temperature of the oil cooler itself, and the temperature of the air moving through the charge air cooler 64 or the temperature of the charge air cooler itself. As the load on each of the coolers, cooling cores, increases, the slats in a particular area open only to the extent necessary to meet the cooling requirements of any particular cooler. None, some, or all of the slats open to the extent necessary to maintain air flow to the coolers to meet the cooling requirements while attempting to minimize the amount of debris laden air drawn by the cooling cores.

[0032] A radiator temperature sensor 92 is operably connected to the radiator and the controller 90. The radiator temperature is identified by the radiator temperature sensor and transmitted to the controller 90. Upon receiving the radiator temperature, the controller transmits a signal to the actuator 80 to adjust the orientation of the slats 60 of the group 74. In one embodiment, the controller 90 compares the radiator temperature with a predetermined value of the radiator temperature to determine whether the slats 60 of the group 74 should be adjusted from the closed position to the open position and from the open position to the closed position. In another embodiment, the controller 90 compares the radiator temperature with a predetermined range of radiator temperature values ​​to adjust the orientation of the slats along a range of orientations from the closed position to a position between the closed position and the open position and to the open position. The range of values ​​is for moving from the open position to the closed position and to an orientation between the open position and the closed position.

[0033] The oil cooler temperature sensor 94 is operably connected to the oil cooler 62 and the controller 90. The oil cooler temperature is identified by the oil cooler temperature sensor 94 and transmitted to the controller 90. Upon receiving the oil cooler temperature, the controller transmits a signal to the actuator 82 to adjust the orientation of the slats 60 of the group 70. In one embodiment, the controller 90 compares the oil cooler temperature with a predetermined value of the oil cooler temperature to determine whether the slats 60 of the group 70 should be adjusted from the closed position to the open position and from the open position to the closed position. In another embodiment, the controller 90 compares the oil cooler temperature with a predetermined range of oil cooler temperature values ​​to adjust the orientation of the slats along a range of orientations from the closed position to a position between the closed position and the open position and to the open position. The range of values ​​is for moving from the open position to the closed position and to an orientation between the open position and the closed position.

[0034] A CAC temperature sensor 96 is operatively connected to the CAC 64 and the controller 90. The CAC temperature is identified by the CAC temperature sensor 96 and transmitted to the controller 90. Upon receiving the CAC temperature, the controller transmits a signal to the actuator 84 to adjust the orientation of the slats 60 of the group 66. In one embodiment, the controller 90 compares the CAC temperature to a predetermined value for the CAC temperature to determine whether the slats 60 of the group 66 should be adjusted from the closed position to the open position and from the open position to the closed position. In another embodiment, the controller 90 compares the CAC temperature to a predetermined range of CAC temperature values ​​to adjust the orientation of the slats along a range of orientations from the closed position to a position between the closed position and the open position and to the open position. The range of values ​​is for moving from the open position to the closed position and to an orientation between the open position and the closed position.

[0035] An additional cooling feature is provided by the fan 48, the speed or blade pitch of the fan being adjusted by the controller 90 using the temperature values ​​of the radiator 28, the oil cooler 62, and the CAC 64. The fan 48 is configured as a variable speed fan, a variable blade pitch fan, or both. The fan speed and / or blade pitch is adjusted based on the orientation of the slats 60 individually or in groups, depending on the sensed temperature. In those instances where the filter needs to be cleaned, the slats are moved to the fully open position and the fan is commanded to reverse pitch to aid in cleaning the filter. In one embodiment, the slats open in response to a command transmitted by the controller when the variable blade pitch is commanded to reverse.

[0036] The user interface 100 is operably connected to the controller 90 and includes a user interface screen or display having a plurality of user selectable buttons to select from a plurality of commands or menus, each of which can be selected by a touch screen having a display. In another embodiment, the user interface includes a plurality of mechanical buttons as well as a touch screen. In another embodiment, the user interface includes a display screen and only mechanical buttons. The user interface 100 is configured to receive input from a user, such as input from an operator of the vehicle 10. In one embodiment, the user interface 100 includes an input device to move the orientation of one or more slats from an open position to a closed position, and vice versa. For example, when the vehicle is traveling on a road between harvesting locations, the slats are moved to a closed position by the operator using a closing feature at the user interface. Since no harvesting is being performed, the engine experiences a reduced load and therefore requires less cooling. By closing the slats, the noise of the vehicle is reduced to meet noise requirements. When the slats are moved to an open position by the operator, the air flow increases and the fan power decreases. In one or more embodiments, the user interface 100 includes a road transport button, and the slats are adjusted based on a predetermined software logic. For example, in one embodiment, the position of the slats is adjusted based on the engine speed or the vehicle speed.

[0037] In another embodiment, the user interface includes a user interface selector to move between manual and automatic control of the slats. For example, when the machine begins harvesting, the user interface is set to the manual position and the slats are set to closed, thereby minimizing the amount of debris ingested by the machine. When the machine moves from this starting state, the user interface is set to the automatic position and the slats are adjusted by the controller 90 receiving the temperature signal from the temperature sensor.

[0038] Figure 5Another embodiment of the arrangement of a control system for controlling the orientation of slats 60A to 60E by a controller 90 is shown. In this embodiment, each slat 60 is operably connected to and moved by a single actuator 102A to 102E. A plurality of temperature sensors 104 are operably connected to the controller 90 and identify the temperature of each of the coolers 28, 62, and 64. In this embodiment, the orientation of each slat 60 can be individually controlled by one of the associated actuators 102. Although the orientation of each slat 60 is individually controllable, the controller 90 is configured to set the orientation of each slat 60 based on a signal received from one of the temperature sensors. For example, adjacent slats 60D and 60E can be positioned in different orientations or the same orientation. In this way, the slat groups can be positioned in the same orientation or in different orientations. Since the slats are individually controllable, the slats that direct air to a single cooler can be positioned in the same orientation or in different orientations.

[0039] As described herein, one or more embodiments enable the air flow to be adjusted to keep dust / debris out of the cooling system in dusty conditions. During specific need times, individual slats are opened to allow increased cooling air mass to flow to coolers that need air without increasing fan speed or pitch angle. By providing adjustable slats, fan power is reduced, which reduces fuel consumption. Cooling capacity is increased, and the amount of dust that clogs the coolers is reduced.

[0040] Although exemplary embodiments incorporating the principles of the present invention have been disclosed above, the present invention is not limited to the disclosed embodiments. On the contrary, the present application is intended to cover any variation, use or modification of the present invention using the general principles of the present invention. For example, although a target is provided during the formation of an axle, in other embodiments the target is a component produced independently of the production of the axle and is fixedly attached to the axle once formed. Therefore, the present application is intended to cover deviations from the present disclosure within the scope of known or customary practice in the field to which the present invention belongs.
