[0002] BACKGROUND ART A traveling vehicle disclosed in Patent Document 1 is known.

[0003] The vehicle disclosed in Patent Document 1 is equipped with an air cleaner that removes dust from air and supplies it to a motor. The air cleaner has an openable lid that can be opened to perform internal maintenance (e.g., cleaning or replacing the element). Therefore, a space for performing air cleaner maintenance is required on the side where the openable lid of the air cleaner is opened.

[0004] Japanese Patent Publication No. 2020-100238

[0005] In the vehicle disclosed in Patent Document 1, the air cleaner is fixedly provided, which has resulted in a problem of limited flexibility in the layout for mounting the air cleaner in order to ensure space for performing maintenance on the air cleaner.

[0006] SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a vehicle that allows for greater freedom in layout for mounting an air cleaner.

[0007] A running vehicle according to one aspect of the present invention comprises a prime mover, an air cleaner that removes dust from air and supplies it to the prime mover, the air cleaner having an opening / closing lid, and a support device that includes a pivotal shaft arranged on the opposite side of the air cleaner from the opening / closing lid and supports the air cleaner so that it can rotate freely around the pivotal shaft, allowing the orientation of the opening / closing lid to be changed.

[0008] The air cleaner may be positioned so that the opening / closing lid faces forward, the pivoting support shaft has an axis extending in the vertical direction and is positioned on the rear side of the air cleaner, and the support device may be configured to be able to pivot the air cleaner outward in the vehicle width direction around the pivoting support shaft.

[0009] The traveling vehicle may include a vehicle body and a support frame fixed to the vehicle body, and the support device may include a fixed stay fixed to the support frame, a movable stay supported by the fixed stay so as to be rotatable around the pivotal axis and attached to the air cleaner, and a fixing device that fixes the movable stay to the fixed stay, and may be configured such that the air cleaner rotates and the orientation of the opening / closing lid is changed by loosening the fixing device and rotating the movable stay around the pivotal axis relative to the fixed stay.

[0010] The work vehicle may be provided with an inlet duct that guides air into the interior of the air cleaner, the air cleaner having an intake section that takes air into the interior of the air cleaner, and the inlet duct may be attached to the intake section so as to rotate integrally with the air cleaner around the pivot shaft.

[0011] The work vehicle comprises a shroud arranged in front of the prime mover and the air cleaner, a cooler arranged in front of the shroud, and an openable and closable bonnet that covers the prime mover, the shroud, and the cooler, the shroud separating the side of the bonnet where the prime mover is located from the side where the cooler is located, the inlet duct extending from the air cleaner side to the front of the shroud and having an air intake portion that takes in air forward of the shroud, and the shroud may have a notch for passing the inlet duct, the notch being open to the side where the inlet duct rotates around the pivot shaft.

[0012] The traveling vehicle may include a seal receiving member that is disposed in the notch and that is attached to the inlet duct so as to extend from the inlet duct toward the open side of the notch, a seal mounting member that is attached to the hood and that is disposed in front of the seal receiving member when the hood is closed, and a seal member that is attached to the rear surface of the seal mounting member and that abuts against the seal receiving member.

[0013] The notch may be formed on a side of the shroud and open outward in the vehicle width direction, and the bonnet may have an outside air intake section that is located outward in the vehicle width direction of the air intake section when the bonnet is closed and takes in outside air into the bonnet, and the air intake section may be formed so as to be bent in the vehicle width direction in a direction away from the outside air intake section.

[0014] The traveling vehicle may be provided with an outlet duct that supplies the air that has been cleaned by the air cleaner to the prime mover, the air cleaner having an air supply section that is the part that sends out the cleaned air from the air cleaner and to which the outlet duct is connected, and at least the connection section of the outlet duct may be formed from an elastic material so that when the air cleaner rotates around the pivot shaft, the connection section that is connected to the air supply section follows the rotation of the air cleaner by elastic deformation.

[0015] The air supply section may be located closer to the rotation support shaft than an intake section that takes air into the air cleaner.

[0016] According to the above-described traveling vehicle, the orientation of the opening / closing cover can be changed by rotating the air cleaner. For example, even if the air cleaner is installed in a location where there is no maintenance space on the side where the opening / closing cover of the air cleaner is opened or closed, the air cleaner can be oriented toward the side where the maintenance space is by rotating the air cleaner and changing the orientation of the opening / closing cover. This increases the degree of freedom in the layout for installing the air cleaner.

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings as appropriate.

[0019] 1 is a schematic side view showing a traveling vehicle 1 according to this embodiment. In this embodiment, a tractor is exemplified as the traveling vehicle 1. In the following, the traveling vehicle 1 will be described as a tractor.

[0020] In this embodiment, the direction of arrow A1 in FIG. 1 (the forward direction of the tractor 1) will be described as the front, and the direction of arrow A2 in FIG. 1 (the reverse direction of the tractor 1) will be described as the rear. Therefore, the back side of FIG. 1 is the left, and the front side of FIG. 1 is the right. Furthermore, the horizontal direction perpendicular to the fore-and-aft direction A3 will be described as the vehicle width direction. The direction from the center of the tractor 1 in the vehicle width direction to the right or left will be described as the vehicle width outward. In other words, the vehicle width outward is the direction in the vehicle width direction that moves away from the center of the tractor 1. The direction opposite to the vehicle width outward is described as the vehicle width inward. In other words, the vehicle width inward is the direction in the vehicle width direction that moves closer to the center of the tractor 1.

[0021] 1, the tractor 1 has a travellable vehicle body 2. The vehicle body 2 has a prime mover E1, a flywheel housing 3, a clutch housing 4, a transmission case 5, and a front axle frame 6.

[0022] The prime mover E1 is a diesel engine. The prime mover E1 is located at the front of the tractor 1 and is covered by a hood 10. The prime mover E1 may be an electric motor, or may be a hybrid type having a diesel engine and an electric motor.

[0023] The flywheel housing 3 is connected to the rear of the prime mover E1. A flywheel is accommodated inside the flywheel housing 3. The clutch housing 4 is connected to the rear of the flywheel housing 3. A clutch that intermittently transmits the power of the prime mover E1 transmitted via the flywheel is accommodated inside the clutch housing 4. The transmission case 5 is connected to the rear of the clutch housing 4. A transmission that changes the speed of the power transmitted via the clutch is accommodated inside the transmission case 5. The transmission has a forward / reverse switching mechanism that rotates the power transmitted by the transmission in the forward or reverse direction to switch the output between forward and reverse.

[0024] The front axle frame 6 is fixed to the prime mover E1 and protrudes forward from the prime mover E1.

[0025] As shown in Figure 1, the tractor 1 has a traveling device 8 that supports the body 2 so that it can travel. The traveling device 8 is a wheel-type traveling device that has left and right front wheels 11L, 11R provided at the front of the body 2 and left and right rear wheels 12L, 12R provided at the rear of the body 2. The left and right front wheels 11L, 11R are supported by a front axle frame 6 via a front axle case (not shown). The left and right rear wheels 12L, 12R are supported at the rear of the transmission case 5.

[0026] As shown in Fig. 1, a driver's seat 13 for a driver (operator) is mounted at the rear of the vehicle body 2. The tractor 1 also includes a cabin 7 surrounding the driver's seat 13.

[0027] As shown in Figures 1, 2 and 8, the hood 10 has left and right side wall portions 14L, 14R, an upper wall portion 15 connecting the upper ends of the left and right side wall portions 14L, 14R, a front grille 16 and lights 17 provided between the front portions of the left and right side wall portions 14L, 14R, and a pair of left and right front lower portions 18 provided below the front portions of the left and right side wall portions 14L, 14R, respectively.

[0028] The front grille 16 is made ventilated so that air outside the hood 10 (outside air) can be taken into the inside of the hood 10. In other words, the hood 10 can take outside air into the inside of the hood 10 from the front side.

[0029] As shown in FIGS. 1 and 2 , the bonnet 10 has an outside air intake 19 for introducing outside air into the interior of the bonnet 10. The outside air intake 19 is provided in the front of each of the left and right side wall portions 14L, 14R of the bonnet 10. The outside air intake 19 is ventilated. That is, the bonnet 10 can introduce outside air into the interior of the bonnet 10 from the front of the side. The outside air introduced through the outside air intake 19 is introduced into the front side of a shroud 20, which will be described later. The underside of the space inside the bonnet 10, which is in front of the shroud 20, is closed by a plate member (not shown). The space inside the bonnet 10 in front of the shroud 20 is partitioned by the bonnet 10, the shroud 20, the plate member, and the like.

[0030] The bonnet 10 has an exhaust section 21 that is open at the lower rear and is formed behind the outside air intake section 19 (shroud 20) in order to exhaust outside air that has been taken into the inside of the bonnet 10.

[0031] The bonnet 10 is pivotally supported by a bonnet shaft 22 (see FIG. 2) located at the upper rear portion of the bonnet 10. The bonnet shaft 22 has an axis extending in the vehicle width direction. The bonnet 10 can be opened and closed by rotating about the bonnet shaft 22 as a fulcrum.

[0032] 1 and 2, a fixed cover 23 is disposed behind the bonnet 10. Similar to the bonnet 10, the fixed cover 23 has left and right side wall portions 23a and an upper wall portion 23b connecting the upper ends of the left and right side wall portions 23a. The fixed cover 23 is attached to a member fixed to the vehicle body 2.

[0033] 2 to 5 show devices, equipment, components, etc. that are arranged inside the hood 10. The devices, equipment, components, etc. that are arranged inside the hood 10 include the engine E1, the air cleaner 24, the inlet duct 25, the outlet duct 26, the exhaust gas purification device 27, the shroud 20, the radiator (cooler) 28, the fuel cooler (cooler) 29, the receiver 30, and the intercooler (cooler) 31.

[0034] The prime mover E1 is as described above. The air cleaner 24 is a device that removes dust from (filters) air and supplies the air to the prime mover E1. The inlet duct 25 is a component that guides air into the air cleaner 24. The outlet duct 26 is a component that supplies the air that has been removed by the air cleaner 24 to the prime mover E1. The exhaust gas purification device 27 is a device that purifies the exhaust gas emitted from the prime mover E1, and is, for example, a DPF (Diesel Particulate Filter). The DPF is a device that captures particulate matter (PM) contained in the exhaust gas from the prime mover E1 and automatically burns and processes the PM.

[0035] The shroud 20 separates the side inside the hood 10 where the prime mover E1 is located from the side where the coolers (radiator 28, fuel cooler 29, intercooler 31, etc.) are located. Therefore, the shroud 20 is disposed in front of the prime mover E1, air cleaner 24, and exhaust gas purification device 27, and is disposed behind the radiator 28, fuel cooler 29, receiver 30, and intercooler 31.

[0036] The shroud 20 has an opening 32 (see FIG. 8 ) that connects the side where the cooler is located with the side where the prime mover E1 is located. A cooling fan 33 (see FIG. 2 ) is disposed in front of the prime mover E1 so as to cover the opening 32 formed in the shroud 20. The cooling fan 33 is driven by the power of the prime mover E1. The cooling fan 33 is a suction fan that draws air from the front and blows it rearward. Therefore, the cooling fan 33 draws outside air into the inside of the hood 10 (the front side of the shroud 20) through the front grille 16 and the outside air intake 19.

[0037] The radiator 28, the fuel cooler 29, the receiver 30, and the intercooler 31 are disposed in front of the shroud 20. Although not shown, other devices disposed in front of the shroud 20 include a condenser and an oil cooler.

[0038] The radiator 28 is a cooler (heat exchanger) that cools the coolant for the engine E1. The fuel cooler 29 is a cooler that cools the fuel (return fuel) returning from the engine E1 before returning it to the fuel tank. The receiver 30 is a device that separates the refrigerant that was not liquefied in the condenser (a cooler that cools the refrigerant that has been semi-liquidized by the compressor to promote liquefaction) from the liquefied refrigerant and removes moisture and impurities. The condenser is located in front of the fuel cooler 29. In addition, an oil cooler is located below the fuel cooler 29. The intercooler 31 is a heat exchanger that cools the high-temperature compressed air sent from the turbocharger (not shown).

[0039] Dust-free air sent out from the air cleaner 24 enters the turbocharger via the outlet duct 26 and also enters the intercooler 31 via the first pipe 34, and is supplied from the intercooler 31 to the prime mover E1 via the second pipe 35.

[0040] As shown in Fig. 4, the air cleaner 24 and the exhaust gas purification device 27 are arranged side by side in the vehicle width direction above the engine E1. As shown in Fig. 3, the air cleaner 24 is arranged to the right of the exhaust gas purification device 27. The air cleaner 24 is arranged so that its central axis X1 is slightly inclined with respect to the front-to-rear direction A3. Specifically, the central axis X1 of the air cleaner 24 extends in an inclined direction that transitions outward (rightward) in the vehicle width direction as it extends forward. The exhaust gas purification device 27 is arranged so that its central axis X2 is along the front-to-rear direction A3. A partition wall 36 is provided between the exhaust gas purification device 27 and the air cleaner 24.

[0041] As shown in FIGS. 3 and 6 , the air cleaner 24 includes a main case 37, an openable / closable lid 38, an element 39, an air intake section 40, an air supply section 41, and an attachment section 42. The main case 37 is formed in a tubular (approximately cylindrical) shape with an open front end and a closed rear end. The openable / closable lid 38 is disposed in front of the main case 37. Therefore, the air cleaner 24 is disposed with the openable / closable lid 38 facing forward. The openable / closable lid 38 is attached to the front end of the main case 37 in an openable / closable manner (e.g., detachable). Therefore, the openable / closable lid 38 closes the opening at the front end of the main case 37. The element 39 is housed inside the main case 37 and the openable / closable lid 38. The element 39 removes dust (filters) from the air introduced into the air cleaner 24. The element 39 can be attached and detached by opening the openable / closable lid 38.

[0042] The intake section 40 is a section that takes in air into the air cleaner 24. The intake section 40 is formed in a cylindrical shape with an axis extending in the vertical direction, and is provided below the rear of the main body case 37. One end (upper end) of the intake section 40 is connected to the right part of the underside of the main body case 37. The intake section 40 extends downward from the main body case 37. The other end (lower end) of the intake section 40 opens downward.

[0043] The air supply section 41 is a section that sends dust-free air from the air cleaner 24 to the outlet duct 26. In other words, the air supply section 41 is a section that sends out dust-free air from the air cleaner 24. The air supply section 41 is formed of a cylindrical body and is provided at the rear of the main body case 37. One end of the air intake section 40 is connected to the rear surface of the main body case 37. The air intake section 40 is also formed so as to bend downward from the rear surface of the main body case 37. The other end of the air intake section 40 opens downward.

[0044] The mounting portion 42 is a portion to which a movable stay 43 (described later) is attached (see FIG. 15 ). The mounting portion 42 is disposed below the front portion of the main body case 37 and is fixed to the lower surface side of the outer circumferential surface of the main body case 37.

[0045] The inlet duct 25 is made of hard resin. As shown in Fig. 6, a connecting portion 25a formed of a cylindrical body is provided on the upper surface of the rear portion of the inlet duct 25. The connecting portion 25a opens upward.

[0046] The connecting portion 25a of the inlet duct 25 is connected to the intake portion 40 of the air cleaner 24. The connecting portion 25a of the inlet duct 25 and the intake portion 40 of the air cleaner 24 are rigidly connected. Therefore, the inlet duct 25 is connected to the air cleaner 24 so as to move integrally with the air cleaner 24.

[0047] 5 and 7, the inlet duct 25 extends forward from the air cleaner 24 side. As shown in FIG. 5, the inlet duct 25 passes through the shroud 20 and extends forward of the shroud 20.

[0048] As shown in Fig. 6, the width of the inlet duct 25 in the vehicle width direction is narrower from the base 25b to the intermediate portion 25c, and is formed to be approximately the same width at the intermediate portion 25c, while the front portion 25d is formed to be narrower than the intermediate portion 25c. As shown in Figs. 2 and 6, the vertical width of the inlet duct 25 in the up-down direction is narrower at the rear portion of the base 25b than the intermediate portion 25c, and is formed gradually wider at the front portion of the base 25b toward the front, and the front portion 25d is formed to be wider than the intermediate portion 25c.

[0049] 8 and 9, the inlet duct 25 has an air intake port 44, which is a portion of the inlet duct 25 that takes in air, located forward of the shroud 20. By locating the air intake port 44 forward of the shroud 20, air forward of the shroud 20 is taken into the air cleaner 24. The air forward of the shroud 20 is air that has just been taken in through the front grille 16 and the outside air intake port 19, and is at a relatively low temperature (lower than the temperature on the side where the prime mover E1 is located). The air intake port 44 is also located forward of the radiator 28 (see FIG. 9).

[0050] 2, the air intake 44 is located to the side (left side) of the outside air intake 19. In other words, when the hood 10 is closed, the outside air intake 19 is located outward (right side) of the air intake 44 in the vehicle width direction.

[0051] 9, the air intake portion 44 is bent so as to face an inclined direction that transitions inward in the vehicle width direction as it moves forward. Therefore, the air intake portion 44 is bent in the vehicle width direction in a direction away from the outside air intake portion 19. In other words, the intake opening 44a, which is the opening for taking in air in the air intake portion 44, faces toward the center in the vehicle width direction.

[0052] However, if the air intake portion 44 is formed to extend forward and the intake opening 44a is designed to face forward, for example, in areas with heavy snowfall, there is a risk that snow will become clogged in the element 39 of the air cleaner 24. More specifically, when air is drawn into the inside of the hood 10 by the cooling fan 33 through the front grille 16 and the outside air intake portion 19, snow will enter the inside of the hood 10 along with the drawn air, and the snow that has entered will enter the inlet duct 25 through the intake opening 44a, flow inside the inlet duct 25, reach the element 39 of the air cleaner 24, and may become clogged in the element 39.

[0053] In contrast, in this embodiment, the air intake portion 44 is formed so that the intake opening 44a faces inward in the vehicle width direction (toward the center of the vehicle body), so snow that has entered the inside of the hood 10 through the front grille 16 and the outside air intake portion 19 is prevented from being sucked into the inside of the inlet duct 25 through the intake opening 44a, thereby preventing snow from clogging the element 39.

[0054] In this embodiment, the air intake portion 44 is bent so as to face in an inclined direction that transitions inward in the vehicle width direction as it moves forward, but this is not limited to this, and the air intake portion 44 may be bent at an angle of approximately 90° with respect to the fore-and-aft direction A3 so as to face inward in the vehicle width direction.

[0055] As shown in Figures 8 and 10 , the shroud 20 has a notch 45 formed therein for passing the inlet duct 25 therethrough. In this embodiment, the notch 45 is formed in the upper right portion of the shroud 20. More specifically, as shown in Figure 10 , the shroud 20 has a shroud main body 46, a protruding wall 47 that protrudes outward in the vehicle width direction from the left side surface of the shroud main body 46, and a protruding wall 48 that protrudes outward in the vehicle width direction from the right side surface. An opening 32 is formed in the shroud main body 46. Furthermore, the radiator 28 is disposed on the front side of the shroud main body 46 so as to close the opening 32.

[0056] The notch 45 is formed in the right-side overhanging wall 48. More specifically, as shown in Fig. 10, the right-side overhanging wall 48 has an upper wall portion 48A and a lower wall portion 48B, and the notch 45 is formed by a lower end 48Aa of the upper wall portion 48A, an upper end 48Ba of the lower wall portion 48B, and an upper portion 46a of the right side surface of the shroud main body 46. Therefore, the notch 45 is open outward in the vehicle width direction.

[0057] 6 and 7, an attachment piece 49 is provided on the upper front portion of the inlet duct 25. The attachment piece 49 is formed integrally with the inlet duct 25 by molding.

[0058] 8 and 10 , the mounting piece 49 is attached to a mounting bracket 50 that is attached to the top of the radiator 28. More specifically, a mounting portion 51 including a nut and a wall portion to which the nut is fixed is provided on the right side of the mounting bracket 50, and the mounting piece 49 is attached to this mounting portion 51 with a fastener 52 (a butterfly bolt in this embodiment). Therefore, the rear portion of the inlet duct 25 is supported by the air cleaner 24, and the front portion is supported by the radiator 28.

[0059] As shown in Figures 5 and 8, the inlet duct 25 passes through an inward portion (left portion) of the cutout 45 in the vehicle width direction. As shown in Figures 5, 6 and 7, the inlet duct 25 is provided with a seal receiving member 53 that protrudes outward (to the right) from the inlet duct 25 in the vehicle width direction. As shown in Figure 8, the seal receiving member 53 is disposed in the cutout 45 (disposed in the outward portion (right portion) of the cutout 45 in the vehicle width direction) and is provided on the inlet duct 25 so as to protrude from the inlet duct 25 toward the open side of the cutout 45.

[0060] 12, the seal receiving member 53 is formed separately from the inlet duct 25 and is fixed to a groove 56 formed in the inlet duct 25. The seal receiving member 53 may also be provided on the inlet duct 25 by integral molding.

[0061] 11 and 12, the seal receiving member 53 is bent downward from the center in the vertical direction, and an upper portion 53b above the bent portion 53a is formed in an inclined shape that slopes rearward as it extends downward, while a lower portion 53c below the bent portion 53a is formed in an inclined shape that slopes forward as it extends downward.

[0062] 11, the lower wall portion 48B of the right-side overhanging wall 48 has an inclination angle at the vertical middle portion and upper portion similar to the inclination angle of the lower portion 53c of the seal receiving member 53. The lower portion of the lower wall portion 48B and the upper wall portion 48A are formed to extend in the vertical direction.

[0063] Incidentally, for example, if the seal receiving member 53 were not bent midway and the entire seal receiving member 53 were formed so as to extend diagonally upward and rearward from the upper portion of the lower wall portion 48B, the width dimension of the seal receiving member 53 in the front-rear direction A3 would increase and the position of the upper wall portion 48A would be moved rearward from the position shown in Figure 11, thereby increasing the width dimension of the entire shroud 20 in the front-rear direction A3. Therefore, in this embodiment, by bending the seal receiving member 53 midway, consideration is given to preventing the width dimension of the shroud 20 in the front-rear direction A3 from increasing.

[0064] The left-side protruding wall 47 is formed to have the same shape as the combined shape of the right-side protruding wall 48 and the shape of the seal receiving member 53 .

[0065] 8, when the tractor 1 has the hood 10 closed, the seal mounting member 54L is disposed in front of the left-side protruding wall 47, and the seal mounting member 54R is disposed in front of the right-side protruding wall 48 and the seal receiving member 53. The seal mounting member 54L is fixed to the inner surface of the side wall portion 14L of the hood 10, and the seal mounting member 54R is fixed to the inner surface of the side wall portion 14R of the hood 10.

[0066] 11 , a seal member 55 is attached to the rear surface of the seal mounting member 54R. The seal member 55 abuts against the seal receiving member 53 when the hood 10 is closed. The seal member 55 also abuts against the upper wall portion 48A and the lower wall portion 48B of the right-side protruding wall 48.

[0067] 8, the seal mounting member 54R covers (seals) the gap between the right-side protruding wall 48 and the seal receiving member 53 and the bonnet 10. The seal member 55 seals the gap between the seal receiving member 53 and the protruding wall 48 and the seal mounting member 54L.

[0068] Similarly, a seal member attached to the rear surface of the left seal mounting member 54L abuts against the left overhang wall 47. The seal mounting member 54L covers (seals) the gap between the left overhang wall 47L and the hood 10. The seal member fixed to the rear surface of the left seal mounting member 54L also seals the gap between the seal mounting member 54L and the left overhang wall 47L.

[0069] The gaps between the other peripheral portions of the shroud 20 and the bonnet 10 are also sealed by appropriate seal members 55 .

[0070] As shown in FIG. 6 , the outlet duct 26 includes a first hose 26A, a second hose 26B, and a connecting pipe 26C connecting the first hose 26A and the second hose 26B. The first hose 26A and the second hose 26B are made of an elastic material such as rubber. The rear portion of the first hose 26A includes a tubular connecting portion 57 that opens upward and has a centerline extending in the vertical direction. The connecting portion 57 is connected to the air supply unit 41. The first hose 26A is bent forward from the lower portion of the connecting portion 57 and then extends forward to be connected to the connecting pipe 26C. One end of the second hose 26B is connected to the connecting pipe 26C. The second hose 26B is routed forward from the connecting pipe 26C to the shroud 20, then folded back and routed rearward (see FIG. 3 ). The other end of the second hose 26B is connected to the turbocharger.

[0071] 3 and 5, in this embodiment, the outlet duct 26 (second hose 26B) and the first pipe 34 that sends high-temperature compressed air to the intercooler 31 are located in front of the air cleaner 24 when it is installed inside the hood 10. The second hose 26B and the first pipe 34 obstruct (hinder) the opening and closing of the opening / closing cover 38 and the attachment and detachment of the element 39.

[0072] Therefore, in this embodiment, as shown in Figure 7, a support device 58 is provided that rotatably supports the air cleaner 24, and the orientation of the open-close lid 38 can be changed by rotating the air cleaner 24. Then, by rotating the air cleaner 24 from its installed position and changing the orientation of the open-close lid 38 to a position where there are no obstacles in the path of installation and removal of the open-close lid 38 and element 39, maintenance of the air cleaner 24 (cleaning, replacement, etc. of the element 39) can be easily performed. Furthermore, by rotating the air cleaner 24, maintenance is facilitated even if there are obstacles in the path of installation and removal of the open-close lid 38 and element 39 before rotation, which increases the degree of freedom in the layout of the air cleaner 24 installation.

[0073] As shown in Fig. 7, the tractor 1 includes a support frame 59 on which the support device 58 is mounted. As shown in Fig. 2, the support frame 59 is fixed to the vehicle body 2 (in this embodiment, the flywheel housing 3).

[0074] As shown in FIG. 7 , a partition wall 60 is attached to the rear of the support frame 59 to separate the inside of the hood 10 from the inside of the cabin 7 .

[0075] As shown in Figures 13 and 14, the support frame 59 has a base bracket 61, a pair of left and right support members 62, an upper bracket 63, a first side frame 64, a second side frame 65, a first bracket body 66, a second bracket body 67, a first support rod 68, and a second support rod 69.

[0076] As shown in FIG. 2, the base bracket 61 is attached to the vehicle body 2 (flywheel housing 3) with bolts or the like.

[0077] As shown in FIGS. 13 and 14, the left and right support members 62 are arranged side by side in the vehicle width direction and fixed to the base bracket 61 in an upright position.

[0078] The upper bracket 63 includes a first bracket 70 and a second bracket 71. The first bracket 70 is formed into a channel shape that opens downward in a side view from the vehicle width direction. The first bracket 70 is disposed between the upper end of the left support member 62L and the upper end of the right support member 62R, and is fixed to the left and right support members 62. The second bracket 71 is bolted onto the first bracket 70. More specifically, the second bracket 71 includes a main member 71A bolted onto the first bracket 70, a plate member 71B fixed to the vehicle width center of the main member 71A, and a reinforcing member 71C welded to the main member 71A and the plate member 71B. The main member 71A includes a pair of left and right support stays 71a. The hood shaft 22 is fixedly mounted to the left and right support stays 71a. The hood shaft 22 is also fixed to the upper end of the plate member 71B.

[0079] The first side frame 64 is provided to extend in an inclined direction that transitions downward as it moves forward from the upper bracket 63 (in this embodiment, the second bracket 71). The upper part of the first side frame 64 is fixed to the second bracket 71, and the lower part of the first side frame 64 is fixed, for example, by bolts, to a member fixed to the prime mover E1 or the like.

[0080] The second side frame 65 is formed in a channel shape that opens to the left when viewed from the front, and is disposed to extend in the front-to-rear direction A3 to the right of the right support member 62R. The front portion of the second side frame 65 is fixed with bolts to a mounting stay 72 that is fixed to the upper part of the right support member 62R.

[0081] The first bracket body 66 is provided on the right side of the upper part of the first side frame 64 .

[0082] The second bracket body 67 is provided on the right side of the lower part of the first side frame 64 .

[0083] The first support rod 68 has an upper portion 68a extending in the vertical direction, an intermediate portion 68b extending diagonally downward and forward from the lower end of the upper portion 68a, and a lower portion 68c extending diagonally right and forward from the lower end of the intermediate portion 68b. The first support rod 68 is fixed to the first bracket body 66. More specifically, the upper portion 68a of the first support rod 68 is fixed to the first bracket body 66.

[0084] Note that the diagonally downward front direction is a direction that changes to the front as it goes downward, and the diagonally right front direction is a direction that changes to the front as it goes to the right.

[0085] The second support rod 69 has an upper portion 69a extending diagonally upward and forward, and a lower portion 69b extending diagonally rearward and rightward from the lower end of the upper portion 69a. The second support rod 69 is fixed to the second bracket body 67. More specifically, the upper portion 69a of the second support rod 69 is fixed to the second bracket body 67.

[0086] Note that the diagonally upward front direction is a direction that shifts forward as it moves upward, and the diagonally rightward rear direction is a direction that shifts backward as it moves rightward.

[0087] As shown in FIG. 14 , the support device 58 includes a fixed stay 73 , a movable stay 43 , a rotation support shaft 74 , and a fixing member 75 .

[0088] As shown in Figures 14 and 17, the fixed stay 73 is formed of a plate material. The fixed stay 73 has a front portion 73a, a left extension portion (first extension portion) 73b extending rearward from the left portion of the front portion 73a, a right extension portion (second extension portion) 73c extending rearward from the right portion of the front portion 73a, and an attachment portion 73d extending upward from the right end of the right extension portion 73c. ​​The fixed stay 73 is placed on the lower portion 68c of the first support rod 68 and the lower portion 69b of the second support rod 69, and its underside is fixed to the lower portion 68c of the first support rod 68 and the lower portion 69b of the second support rod 69. The attachment portion 73d of the fixed stay 73 is fixed to the rear portion of the second side frame 65 with a bolt (see Figure 13).

[0089] As shown in Figure 17, a boss 76 made of a cylinder with an axis extending in the vertical direction is fixed to the underside of the left extending portion 73b. A shaft insertion hole 77 communicating with the boss 76 is formed in the left extending portion 73b. A nut member 78 is fixed to the underside of the right portion of the front portion 73a. A screw insertion hole 79 communicating with the screw hole of the nut member 78 is formed in the right portion of the front portion 73a. Through holes 80 extending in the vertical direction are provided in the left portion of the front portion 73a and in the right portion of the front portion 73a to the left of the screw insertion hole 79. The through holes 80 have an oval shape that is long in the circumferential direction and centered on the axis of the boss 76 (the axis of the rotation support shaft 74 inserted into the boss 76).

[0090] 14 and 17, the movable stay 43 is formed from a plate material. The movable stay 43 is disposed so as to be stacked on the fixed stay 73. The movable stay 43 has, at the rear of the left part, a supported portion 84 including a shaft insertion hole 81 through which the rotation support shaft 74 is inserted. A guide groove 82, which is an arc-shaped elongated hole centered on the axis of the shaft insertion hole 81 (the axis of the rotation support shaft 74 inserted in the shaft insertion hole 81), is formed at the right part of the movable stay 43.

[0091] As shown in Figure 15, the movable stay 43 is disposed on the underside of the air cleaner 24 and attached to the air cleaner 24. More specifically, the movable stay 43 is placed on the underside of the mounting portion 42 of the air cleaner 24 and attached to the mounting portion 42 with four bolts 83. As shown in Figure 17, the heads of the two rear bolts 83 are inserted into the through holes 80. The heads of the two front bolts 83 are located in front of the fixed stay 73.

[0092] As shown in Figures 13 and 14, the pivot shaft 74 has an axis extending in the vertical direction. The pivot shaft 74 is inserted through the shaft insertion hole 81 of the movable stay 43 and the shaft insertion hole 77 of the fixed stay 73, and is inserted into the boss 76. As a result, the movable stay 43 is supported by the fixed stay 73 so as to be rotatable about the axis of the pivot shaft 74 (around the pivot shaft 74). Therefore, the air cleaner 24 and the inlet duct 25 rotate together with the movable stay 43 around the pivot shaft 74. Rotation of the air cleaner 24 around the pivot shaft 74 changes the orientation of the opening-closing lid 38. In other words, the support device 58 supports the air cleaner 24 so as to be rotatable about the pivot shaft 74, allowing the orientation of the opening-closing lid 38 to be changed.

[0093] In this embodiment, a bushing is inserted into the boss 76. That is, the rotation support shaft 74 is inserted into the boss 76 via the bushing. This allows the air cleaner 24 to rotate smoothly.

[0094] 15, the pivot shaft 74 is disposed on the opposite side (the rear side in this embodiment) of the air cleaner 24 from the opening / closing cover 38. This allows the orientation of the opening / closing cover 38 to be easily changed by rotating the air cleaner 24 about the pivot shaft 74.

[0095] 13 and 14 , the fixing device 75 fixes the movable stay 43 to the fixed stay 73. In this embodiment, the fixing device 75 is configured as a knob bolt. Therefore, the fixing device 75 can be rotated by gripping the knob, and an operator can manually tighten and loosen the fixing device 75.

[0096] The fixing device 75 has a threaded shaft portion 75a (a shaft portion with a male thread cut on the outer periphery), and the threaded shaft portion 75a is inserted through the guide groove 82 and screwed into the nut member 78. By tightening the fixing device 75, the movable stay 43 is fixed so as not to rotate relative to the fixed stay 73. By loosening the fixing device 75, the movable stay 43 becomes rotatable around the rotation support shaft 74 within the range of the guide groove 82 (the range of the elongated hole).

[0097] Fig. 16 shows a schematic plan view of the air cleaner 24 and inlet duct 25 installed inside the hood 10 (installed state), and the support device 58 in the installed state of the air cleaner 24. Fig. 17 shows a plan view of the support device 58 in the installed state of the air cleaner 24, etc.

[0098] When the air cleaner 24 is in the installed state, the screw shaft portion 75a of the fixing device 75 is located at the right end of the guide groove 82. Furthermore, the head of the rear bolt 83 is located at the left end of the corresponding through hole 80. Therefore, the movable stay 43 can rotate outward (to the right) in the vehicle width direction about the rotation support shaft 74. In other words, the air cleaner 24 and the inlet duct 25 can rotate together outward (to the right) in the vehicle width direction about the rotation support shaft 74 from the installed state position.

[0099] To rotate the air cleaner 24 and the inlet duct 25 from the installed state around the axis of the pivot shaft 74, first, the hood 10 is rotated upward around the hood shaft 22 to open the hood 10. Next, the fastener 75 securing the front portion of the inlet duct 25 is removed. Thereafter, the fastener 75 securing the movable stay 43 is loosened, and the air cleaner 24 or the inlet duct 25 is grasped and rotated to the right. As a result, as shown in FIGS. 18 and 19 , the movable stay 43 rotates to the right around the pivot shaft 74. At this time, the head of the bolt 83 moves toward the right end of the through-hole 80, and the threaded shaft 75 a of the fastener 75 moves relatively to the left end of the guide groove 82, causing the air cleaner 24 and the inlet duct 25 to rotate to the right (outward in the vehicle width direction). As a result, the orientation of the opening / closing lid 38 is changed so that it faces diagonally forward further to the right than the orientation in the installed state. After the orientation of the opening / closing lid 38 is changed, there is no obstacle in front of the opening / closing lid 38 that would hinder opening and closing of the opening / closing lid 38 or attachment and detachment of the element 39, so opening and closing of the opening / closing lid 38 and attachment and detachment of the element 39 can be easily performed.

[0100] Furthermore, when the inlet duct 25 rotates integrally with the air cleaner 24, the connecting portion 57 of the outlet duct 26 elastically deforms to follow the rotation of the air cleaner 24, thereby allowing the air cleaner 24 to rotate.

[0101] It is sufficient that at least the connection portion 57 of the outlet duct 26 is made of an elastic material.

[0102] 15 , the air supply unit 41 is located closer to the pivot shaft 74 than the air intake unit 40. In other words, the connection part 57 connected to the air supply unit 41 is located closer to the pivot shaft 74. By rotating the air cleaner 24 around a pivot point located close to the connection part 57, there is an advantage that the amount of elastic deformation of the connection part 57 when the air cleaner 24 is rotated around the pivot shaft 74 can be reduced.

[0103] Furthermore, when the air cleaner 24 is rotated, the inlet duct 25 also rotates together with the air cleaner 24, but the notch 45 through which the inlet duct 25 passes is open outward (to the right) in the vehicle width direction. In other words, the notch 45 is open on the side on which the inlet duct 25 rotates about the rotation support shaft 74, and therefore rotation of the inlet duct 25 about the rotation support shaft 74 is permitted. In other words, when the inlet duct 25 is disposed forward of the shroud 20 by passing through a part of the shroud 20, the inlet duct 25 does not penetrate a part of the shroud 20, but is provided in the shroud 20 with a notch 45 that is open on the side on which the inlet duct 25 rotates about the rotation support shaft 74, and the inlet duct 25 passes through this notch 45, so that the inlet duct 25 can rotate together with the air cleaner 24.

[0104] The present invention is not limited to the above embodiment. For example, the air cleaner 24 is configured to rotate integrally with the inlet duct 25. However, the connecting portion 25a of the inlet duct 25 connected to the intake section 40 may be formed of an elastic member, so that when the air cleaner 24 rotates, the connecting portion 25a of the inlet duct 25 elastically deforms to follow the rotation of the air cleaner 24. Furthermore, while the pivot shaft 74 has an axis extending in the vertical direction, the pivot shaft 74 may be arranged so that its axis extends in the vehicle width direction, allowing the orientation of the opening / closing cover 38 to be changed upward. In other words, the direction of the axis of the pivot shaft 74 is not limited to this embodiment, and the direction in which the opening / closing cover 38 can be changed is not limited to this embodiment. The design of the notch 45 can be modified as appropriate to correspond to the direction in which the opening / closing cover 38 can be changed.

[0107] According to the traveling vehicle 1 of this item 1, the orientation of the opening / closing lid 38 can be changed by rotating the air cleaner 24. For example, even if the air cleaner 24 is installed in a location where there is no maintenance space on the side where the opening / closing lid 38 of the air cleaner 24 is opened or closed, the air cleaner 24 can be oriented toward the side where there is maintenance space by rotating the air cleaner 24 and changing the orientation of the opening / closing lid 38.
