Description

  The present invention relates to a multipurpose vehicle in which an engine compartment is arranged behind a passenger compartment.

  Patented a riding mower with a driver's seat located in the center of the fuselage frame that is supported by the front and rear wheels, and a transmission and an engine or engine accessory behind the driver's seat. Known from document 1. In this riding mower, the transmission is provided with a transmission cooling fan, and the engine is provided with an engine cooling fan. Further, an oil cooler is disposed between the transmission cooling fan and the engine cooling fan. The transmission cooling fan sucks outside air in front of the vehicle body to cool the transmission, and the engine cooling fan sucks outside air behind the driver seat to cool the engine. The oil cooler is cooled by the flow of outside air by both fans. Since the cooling fan configuration according to Patent Document 1 includes two fans, the structural and cost burden is large.

  Further, Patent Document 2 also discloses a work vehicle in which an engine and an engine accessory are arranged behind the driver seat. In this work vehicle, in the engine room covered with the bonnet, an engine is disposed at the rear portion of the vehicle body, and a radiator is disposed on the vehicle body front side of the engine. A cooling fan is disposed between the radiator and the engine. The gap between the cooling fan and the bonnet is closed by a shroud. Openings covered with a dust net functioning as an engine cooling air inlet are formed at the front end and both front side surfaces of the bonnet. The engine cooling intake port is open toward both lateral outer sides and upper side of the vehicle body. Due to the air blowing action of the cooling fan driven by the engine, the air outside the bonnet is sucked into the vicinity of the radiator in the bonnet from the engine cooling inlet and flows into the engine through the radiator. In this cooling fan configuration, a good cooling effect can be obtained if a free space in which air freely flows is ensured between the front surface of the radiator and the engine cooling intake ports formed at a plurality of locations of the bonnet. However, when such a free space cannot be ensured, the air flow becomes worse and effective cooling becomes difficult.

JP 2009-240214 A (paragraph number [0020-0050], FIG. 1 and FIG. 2: corresponding foreign application US2009 / 0241498A1) JP 2008-074293 A (paragraph number [0012-0015], FIG. 1, FIG. 3: corresponding foreign application US7527298B1)

  In view of the above circumstances, there is a demand for a multi-purpose vehicle that can efficiently cool not only the engine disposed behind the passenger compartment but also a heat radiator such as an oil cooler.

  A multipurpose vehicle according to the present invention includes a vehicle body extending in the front-rear direction, a passenger compartment formed in the vehicle body, a front chamber formed in the vehicle body in front of the passenger compartment, and a vehicle body in the rear of the passenger compartment. The engine chamber formed, the radiator disposed in the front chamber, the engine disposed in the engine chamber, the radiator disposed below the passenger compartment, and the air in the front space of the radiator A fan that is drawn through a radiator and sent to the engine, a shroud that covers the periphery of the fan, and an air intake port provided on one side of the vehicle body to guide outside air to the front space of the radiator, at least below the vehicle body And an air guide plate unit having an air guide bottom plate for preventing the flow of outside air from the air.

  In this configuration, the external air taken from one side of the vehicle body flows into the front surface of the radiator, and further passes through the radiator by the suction force of the fan and reaches the engine in the engine compartment. The external air that still has sufficient cooling capacity even after passing through the radiator is discharged from the rear while cooling the engine and other devices arranged in the engine room. At this time, the air guide plate unit forms a passage from the air intake port to the front space of the radiator, and the air guide bottom plate prevents air from flowing in from the lower side of the vehicle body. This eliminates the problem that hot air that passes through the radiator disposed at the front of the vehicle body and flows below the vehicle body flows into the engine compartment through the radiator.

  In this specification, unless specifically defined, the phrase “position” indicating the positional relationship represents the forward side in the vehicle traveling direction, and “rear” represents the reverse side. Accordingly, the longitudinal direction of the vehicle body represents the longitudinal direction of the vehicle body, and the transverse direction of the vehicle body represents the width direction (left-right direction) of the vehicle body. The side of the vehicle body represents the positional relationship from the center in the vehicle body width direction.

  In order to sufficiently take in external air from one side of the vehicle body, that is, from the air intake port provided at the left end or right end in the vehicle body width direction, the intake air in the space inside the air intake port and the vehicle components It is necessary to avoid interference as much as possible. For this reason, in one preferred embodiment of the present invention, an air intake chamber is formed on one side of the vehicle body, and the air intake port is provided on a side end wall of the air intake chamber.

  Since it is important to increase the cooling efficiency that the external air flowing from the air intake port to the front space of the radiator does not flow as much as possible, the air guide plate unit covers the front surface of the radiator. It is preferably formed as a duct. By adopting a substantially closed duct structure, not only the air taken in from the air intake port leaks but also other hot air and dust can be prevented from flowing into the intake air (fresh air).

  As one preferred embodiment of the present invention, if the air guide duct adopts a structure connected to the shroud, the sealability of the flow path of the outside air from the air intake port to the fan is ensured, and Since air passes through the radiator without loss and flows into the engine space, not only the engine but also a radiator such as an oil cooler can be cooled more efficiently.

  In the passenger compartment, passenger seats such as a driver seat and a passenger seat are provided. For this reason, effective use below the passenger seat is important for making the vehicle compact. For this reason, in one preferred embodiment of the present invention, an occupant seat is provided in the occupant room, and the fan, the radiator, and the air guide plate unit are located below the occupant seat. Yes.

  Before describing a specific embodiment of a multi-purpose vehicle having a cooling structure according to the present invention, the basic structure will be described with reference to FIG.

  In this vehicle, a front chamber FR, a passenger compartment Cn, and an engine compartment ER are formed from the front to the rear in a vehicle body 10 extending in the vehicle front-rear direction (traveling direction). A radiator 33 and an air cleaner 34 are arranged in the front room FR, and a seat and a steering device on which the occupant sits are arranged on the floor of the passenger compartment (which may be a sealed space or an open space) Cn. A radiator 32 such as an oil cooler is disposed below the passenger compartment Cn. An engine 30 and a transmission (power transmission device including a transmission) 37 are disposed in the engine chamber ER. In order to cool the radiator 32, a fan 76 that draws air in the space in front of the radiator 32 through the radiator 32 and sends it to the engine 30 is disposed before or after the radiator 32. A shroud 77 is provided around the fan 76 so that the air flow is efficiently generated by the fan 76.

  The hot air is directed downward so that the hot air that has passed through the radiator 33 does not enter the passenger compartment Cn. A wind guide bottom plate 71 is provided in front of the radiator 32 to prevent the outside air from flowing in from below the vehicle body so that the hot air passing under the vehicle flows in front of the radiator 32 and does not pass through the radiator 32. A wind guide plate unit 70 is provided. Further, the air guide plate unit 70 also creates an air guide path that guides outside air from the air intake port 75a provided on one side of the vehicle body 10 (left side of the vehicle body in FIG. 1) to the front space of the radiator 32. . As shown in FIG. 1, a wind guide bottom plate 71 is extended from the radiator 32 to the air intake port 75a, and a structure such as a partition disposed above the wind guide bottom plate 71 between the front chamber FR and the passenger compartment Cn. If a member or a vehicle device such as a battery is not positioned, outside air will flow into the radiator 32. In order to make the intake of the air flow into the radiator 32 more reliable, an air intake chamber 55 that forms a space that circulates with the outside air is formed on the side of the vehicle body, and the outside opening is used as an air intake port 75a. The inner opening may be connected to the wind guide bottom plate 71. Further, when the air guide side plate 72 is erected on both side ends of the air guide bottom plate 71, a groove-like air flow path is created, so that air smoothly flows from the air intake chamber 55 to the radiator 32. In the example of FIG. 1, the wind guide plate unit 70 is formed as a wind guide duct by covering the wind guide top plate 74 on the upper end of the wind guide side plate 72, but the upper side of the wind guide bottom plate 71 is covered with a floor panel or the like. If it is, the air guide top plate 74 and, in some cases, the air guide side plate 72 can be omitted. In any case, the air guide plate unit 70 makes it possible to take in outside air from the side of the vehicle, and a fresh cooling air flow flows into the radiator 32, and the air flow that has passed through the radiator 32 further flows into the engine 30. And the transmission 37 is cooled.

When the loading platform 11 is swung up and down by an expansion and contraction operation of a dump cylinder (not shown), the load is discharged.

  A radiator 33 for cooling the engine is provided in the central region of the front chamber FR covered by the bonnet 2 in the center in the left-right direction (the vehicle transverse direction). The radiator 33 is provided with a radiator fan 33 a that sucks and introduces outside air through a front grill provided on the front wall of the bonnet 2. The air flow warmed by the radiator 33 is caused to flow backward from the lower side of the vehicle body. The radiator 33 may be provided with a condenser of an air conditioner for the passenger compartment Cn. Further, an air cleaner 34 is disposed in a side region of the front chamber FR, here the right region, and the air cleaner 34 and the engine 30 are connected by an intake duct 35.

  A transmission 37 that transmits the driving force from the engine 30 to the front wheels 1 a and the rear wheels 1 b is disposed behind the engine 30. The transmission 37 includes a continuously variable transmission 37a and a gear transmission 37b, which are HSTs. The gear transmission includes a multi-stage gear transmission mechanism, a rear wheel differential mechanism, and the like.

  The engine 30 is arranged in a posture in which the axis of its output shaft (crankshaft, not shown) is set in the front-rear direction, and a transmission shaft (not shown) connected to the output shaft is connected to the transmission 37 in the front-rear direction. By making it penetrate, the driving force of the engine 30 is transmitted to the hydraulic pump of the HST 37 a, and further the driving force from the hydraulic motor of the HST 37 a is transmitted to the transmission 37. It is transmitted to the rear wheel differential mechanism of the transmission 37 and the left and right rear wheels 1b. Power for driving the front wheels is transmitted from a lower output shaft (not shown) formed on the front side of the transmission 37 to the front wheel differential mechanism 37e via the drive shaft 37d, and further transmitted from the front wheel drive shaft 37f to the left and right front wheels 1a. The transmission system is configured as follows.

  The engine 30 is provided with an intake manifold 30a to which air is supplied from an air cleaner 34 via an intake duct 35 on the right side of the upper surface thereof, and with an exhaust manifold 30b on the left side of the engine 30, and between the exhaust manifold 30b and the muffler 38.

The cooling device for cooling the oil cooler 32 includes an air guide plate unit 70 that guides cooling air, and a fan 76 that creates a cooling air flow that passes through the oil cooler 32. The fan 76 is attached immediately behind the oil cooler 32, and a shroud 77 that covers the fan 76 is provided between the fan 76 and the oil cooler 32. In this embodiment, the air guide plate unit 70 is formed as an air guide duct 70, and an air intake chamber 75 is formed on the upstream side of the air guide duct 70. The air intake chamber 75 is arranged close to the side of the vehicle body 10 below the passenger compartment Cn, in this embodiment, below the driver seat 47. An air intake port 75 a is formed on a boundary surface in contact with the outside of the air intake chamber 75. That is, the outside air that can be taken in from one side of the vehicle reaches the oil cooler 32 through the air intake chamber 75 and the air guide duct 70 as a cooling air flow, and the cooling air flow that passes through the oil cooler 32 is the engine room ER. The engine 30, the transmission 37 and the muffler 38 are cooled.

  As is clear from FIG. 5, the passenger compartment Cn is bounded to the lower space of the vehicle body 10 by a floor plate (floor panel) 49. A driver seat 47 and a passenger seat 48 are formed on a floor plate 49 on which a step is formed by a seat mounting frame standing on the frame-like vehicle body 10. A partition wall 80 that separates the engine compartment ER and the loading platform 11 from the passenger compartment Cn is provided behind the driver seat 47 and the passenger seat 48. The oil cooler 32 is disposed inside the seat mounting frame 12. The fan 76 is fixed to the front output shaft 30 c of the engine 30. The wind guide plate unit 70 formed as a wind guide duct includes a connection cover 78 that covers the oil cooler 32 and is connected to the shroud 77 of the fan 76 in the end region on the oil cooler 32 side. Thus, the air flow path extending from the air intake chamber 75 to the fan 76 via the oil cooler 32 becomes a substantially sealed space, and fresh air taken from the side of the vehicle flows into the engine chamber ER as it is.

  As is apparent from FIG. 2, the passenger compartment Cn is provided to be openable and closable with respect to the round pipe made of the Lopps frame assembly 4 and the openings for getting on and off the left and right sides of the Lops frame assembly 4 respectively. Door 45 is provided. The lops frame assembly 4 includes a left frame portion 4a, a right frame portion 4b, a front cross bar 4c, and a rear cross bar 4d. The left frame portion 4a and the right frame portion 4b have a gate shape. The front crossbar 4c connects the front upper end of the left frame portion 4a and the front upper end of the right frame portion 4b, and the rear crossbar 4d connects the rear upper end of the left frame portion 4a and the rear upper end of the right frame portion 4b. Yes. The front leg portion of the left frame portion 4a functions as the left pillar 41, and the rear leg portion of the left frame portion 4a functions as the left rear pillar 43. The front leg portion of the right frame portion 4b functions as the right pillar 42, and the rear leg portion of the right frame portion 4b functions as the right rear pillar 44. A detachable windshield 5 is disposed at the front of the passenger compartment Cn. The windshield 5 is detachably attached to the left pillar 41 and the right pillar 42 using the windshield mount unit 6.

  As shown in FIG. 6, a steering wheel 46, various operation switches, and a display device are arranged on the front panel in front of the driver seat 47, and an accelerator pedal 9 is arranged near the bottom plate 49. Yes. The accelerator pedal 9 is shown in detail in FIG. 7, but a parallel link mechanism 90 is provided in its operation displacement transmission system. The parallel link mechanism 90 includes a pedal bracket 91 provided on the back surface of the upper portion of the pedal 9, a fixed bracket 92 fixed to the vehicle body side, a lower link plate 93a connecting the pedal bracket 91 and the fixed bracket 92, and It consists of an upper link plate 93b. A bifurcated rocking arm 95 is fixed to a rocking shaft 94 movably connecting the fixed bracket 92 and the lower link plate 93 a, and an operation cable 96 is connected to one arm portion of the bifurcated rocking arm 95. doing. The other arm portion of the bifurcated swing arm 95 functions as a stopper. Since the depression displacement of the accelerator pedal 9 is transmitted to the operation cable 96 via the parallel link mechanism 90 such as steam, the ratio between the pedal depression force and the operation force and the ratio between the pedal depression amount and the operation cable displacement amount can be freely selected. This improves the vehicle speed and enables a good vehicle speed adjustment. Further, the lower link plate 93a and the upper link plate 93b are formed of plates substantially parallel to the pedal tread surface, which contributes to space saving in the longitudinal direction of the vehicle body. Further, since the pedal depression force acts as a compression force and a pulling force of the parallel link mechanism 90, the strength in the vehicle body width direction can be ensured.

  FIG. 8 shows a muffler 38 used in this multipurpose vehicle. As is well known, the muffler 38 includes a housing 38a, an inner tube 38b that has entered the inner space of the housing 38a, and a cylindrical sound deadening provided on the inner peripheral surface of the housing 38a so as to surround the inner tube 38b. It consists of chamber 38c. The sound deadening chamber 38c is filled with glass wool or SUS wool. Since the structure of the muffler 38 is well known, a detailed description thereof is omitted here. However, as an unprecedented structure, a check valve CV is provided in the drain pipe 38d connected to the sound deadening chamber 38c. ing. The check valve CV is closed during engine idling operation because the muffler internal pressure is low, and is closed. When the engine is rotating at high speed or medium speed, the check valve CV is set to open when the muffler internal pressure increases. As a result, the check valve CV is closed while the vehicle is stopped or traveling at a low speed in idling operation, so that the problem of exhaust odor leaking from the drain pipe 38d is solved. Although the check valve CV is opened during normal traveling, the possibility of exhaust odor leaking from the drain pipe 38d reaching the driver is low.

  Further, the exhaust port 36x of the downstream exhaust pipe 36b connected to the muffler 38 shown in FIG. 8 is oriented so that the exhaust gas exiting from the exhaust port 36x faces downward. In the illustrated embodiment, the deflector plate is covered with the upper cut surface of the exhaust port cut in a mountain shape, and the lower cut surface is the exhaust port 36x. Alternatively, the exhaust gas discharge direction of the exhaust port 36x may be deflected by bending the rear end portion of the downstream exhaust pipe 36b. Further, as shown in FIG. 9, by attaching the downstream exhaust pipe 36b to the muffler 38 at a plurality of pitches in the circumferential direction, the direction of the exhaust gas from the exhaust port 36x can be made variable. is there.

  10 and 11 show the spark arrester 39 interposed in the downstream exhaust pipe 36b. The spark arrester 39 includes a cylindrical case body made up of a half-cylindrical first housing 39a and a second housing 39b, and a screen 39c stretched across the boundary surface. One edge portions of the first housing 39a and the second housing 39b extending in the axial direction are oscillated and connected to each other by a lock lever 39d having a well-known lever type quick clamp structure. Closed linked. The connection between the screen 39c at the edge of the first housing 39a and the second housing 39b may be performed with a metal gasket interposed therebetween. The internal space of the housing is divided into a first space defined by the first housing 39a and the screen 39c and a second space defined by the second housing 39b and the screen 39c. The downstream exhaust pipe 36b is divided into a first downstream exhaust pipe 39x and a second downstream exhaust pipe 39y. The first downstream exhaust pipe 39x opens into the first space, and the second downstream exhaust pipe 39y enters the second space. It is open. Therefore, the exhaust gas discharged from the first downstream exhaust pipe 39x passes through the screen 39c, flows into the second space, and flows into the second downstream exhaust pipe 39y. Since the screen 39c is exposed by operating the lock lever 39d to the unlock position and opening the first housing 39a and the second housing 39b, the cleaning of the screen 39c becomes easy.

  In this multipurpose vehicle, HST is used as the continuously variable transmission 37a. The HST drives the hydraulic pump using the engine output, and outputs the rotational power by driving the hydraulic motor with the hydraulic pressure generated by the hydraulic pump. Shift output can be obtained by making the hydraulic pump and / or the hydraulic motor variable output type. When stopping from a state where the hydraulic motor is normally or reversely driven, the hydraulic pump or the hydraulic motor is operated neutrally, and a mechanical brake or the like is used in combination to improve the stop response. At that time, unnecessary kinetic energy is converted into heat energy and discarded. In order to suppress such energy loss, a power generation device that operates when stopped on the shaft of the hydraulic motor is provided.
