Description

[Technical Field]

[0001] The present application relates to vehicles. [Background technology]

[0002] Vehicles that drive mounted equipment using actuators are known (for example, see Patent Document 1 below). The actuators are operated by hydraulic oil supplied by a hydraulic pump. The hydraulic oil is stored in a hydraulic oil tank. In Patent Document 1, the PTO (Power Take Off) and hydraulic pump are located on the port side, and the hydraulic oil tank is located on the starboard side. Furthermore, on-board items such as a spare tire and a basket are often located on the port side, between the driver's cab and mounted equipment.

[0003] In Patent Document 1, the hydraulic pump is located below the mounted structure, but there is a demand to locate the hydraulic equipment (hydraulic pump, oil tank, etc.) near the PTO, specifically between the driver's cab and the mounted structure. However, if the hydraulic equipment is located on the port side between the driver's cab and the mounted structure, it is difficult to secure space for mounting items such as a spare tire or a basket.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-252555 Summary of the Invention [Problem to be solved by the invention]

[0005] Therefore, the problem is to provide a vehicle that can secure space for carrying on-board equipment. [Means for solving the problem]

[0006] The vehicle comprises a driver's cab, a body frame extending rearward from a lower portion of the driver's cab, a mounted object arranged above the body frame, an actuator for driving the mounted object, a control valve for adjusting the hydraulic pressure of hydraulic oil supplied to the actuator, a hydraulic pressure generating source for supplying the hydraulic oil to the control valve, an oil tank for storing the hydraulic oil, and a hydraulic hose for connecting the hydraulic pressure generating source and the oil tank, When viewed from the up-down direction, the hydraulic pressure generating source, the oil tank, and the hydraulic hose are located between the driver's cab and the mounted object, on one side of the vehicle width direction of a predetermined reference plane that extends in the up-down direction and the fore-and-aft direction of the vehicle. In this specification, "the hydraulic power source, the oil tank, and the hydraulic hoses are disposed between the cab and the mounted object" refers not only to the case where the entire hydraulic power source, the oil tank, and the hydraulic hoses are disposed between the cab and the mounted object, but also to the case where at least a portion of the hydraulic power source, the oil tank, and the hydraulic hoses in the vehicle longitudinal direction are disposed between the cab and the mounted object. For example, the hydraulic power source, the oil tank, and a portion of the hydraulic hoses may be disposed between the cab and the mounted object, and the remaining portions of the hydraulic power source, the oil tank, and the hydraulic hoses may overlap the cab or the mounted object when viewed from above. Furthermore, any one of the hydraulic power source, the oil tank, and the hydraulic hoses may be disposed entirely between the cab and the mounted object, and only a portion of the others may be disposed between the cab and the mounted object.

DETAILED DESCRIPTION OF THE INVENTION

[0008] In each drawing, the dimensions of the components may be enlarged or reduced relative to the actual dimensions, for example, to facilitate understanding, and the dimensional ratios between the drawings may not be consistent. Note that in each drawing, for example, to facilitate understanding, some of the components may be omitted.

[0009] Terms including ordinal numbers such as "first" and "second" are used to describe various components, but these terms are used only to distinguish one component from another, and the components are not particularly limited by these terms. The number of components including ordinal numbers is not particularly limited, and may be, for example, one. Furthermore, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0010] An embodiment of a vehicle will be described below with reference to Figures 1 to 9. Note that the following embodiment is provided as an example to aid in understanding the configuration of the vehicle, and is not intended to limit the configuration of the vehicle.

[0011] Fig. 1 shows a refuse collection truck G as an example of a vehicle. In Fig. 1, the front-to-rear direction (also referred to as the vehicle front-to-rear direction) and the up-to-down direction of the refuse collection truck G are indicated by arrows, and the direction perpendicular to the paper surface is the left-to-right direction (also referred to as the vehicle width direction).

[0012] As shown in FIG. 1, the refuse collection vehicle G comprises a driver's cab C, a body frame F extending rearward from the bottom of the driver's cab C, a refuse collection box B that is disposed rearward of the driver's cab C and above the body frame F and that contains refuse, and a refuse drop box T that is connected to the rear end of the refuse collection box B. The refuse collection vehicle G also comprises a loading device 2 that loads refuse that has been dropped into the refuse drop box T into the refuse collection box B. The refuse collection vehicle G also comprises a discharge device 1 that discharges the refuse that has been loaded into the refuse collection box B.

[0013] The trash collection box B has a bottom wall B1 and a top wall B2 that face each other in the vertical direction, a pair of side walls B3, B3 that connect the left and right ends of the bottom wall B1 and the top wall B2, and a front wall B4 that connects the front ends of the bottom wall B1 and the top wall B2. The rear surface of the trash collection box B is inclined backward from its top to its bottom, and a rear end opening (not shown) is open across the entire surface.

[0014] As shown in Figure 1, the garbage collection box B is mounted on the body frame F of the garbage collection vehicle G, and the bottom wall B1 of the garbage collection box B forms a gentle slope that slopes downward toward the rear. The garbage collection box B has a lower frame B5 below the bottom wall B1, and is fixed to the body frame F via the lower frame B5.

[0015] 1, the discharge device 1 provided in the trash collection box B will be described. The discharge device 1 has a discharge plate 10 that can move forward and backward relative to the trash drop box T, and a storage space B6 for storing trash is formed behind the discharge plate 10 (between the discharge plate 10 and the rear end opening inside the trash collection box B).

[0016] The discharge plate 10 is composed of a discharge plate body 10a that spans almost the entire width of the internal space of the trash collection box B, and a support frame 10b that is integrally connected to the back surface of the discharge plate body 10a. A guide mechanism 11 is provided between the discharge plate 10 and the trash collection box B to guide and support the discharge plate 10 so that it can slide back and forth in an upright position.

[0017] A single-stage or multi-stage (telescopic) hydraulic discharge cylinder 12 that drives the discharge plate 10 back and forth is connected between the back surface of the discharge plate 10 and the garbage collection box B. The discharge cylinder 12 is arranged to extend in the front-to-rear direction substantially along the bottom wall B1 of the garbage collection box B.

[0018] With the above configuration, when the storage space B6 is empty, the discharge plate 10 is in an initial position (solid line in Figure 1) located slightly forward of the discharge position, and the garbage loaded into the garbage storage box B by the loading device 2 is compressed between the loading device 2 and the discharge plate 10. Then, as the amount of garbage loaded increases, the discharge cylinder 12 gradually contracts, moving the discharge plate 10 forward until it moves to the forward position shown by the two-dot chain line in Figure 1, thereby expanding the storage space B6. Also, by extending the discharge cylinder 12 and moving the discharge plate 10 to a rear position protruding from the garbage storage box B, the garbage stored in the garbage storage box B can be discharged to the outside.

[0019] In this embodiment, an example of a discharge plate type in which garbage loaded into the garbage storage box B is discharged by moving the discharge plate 10 is shown, but this is not limited to this, and a dump type in which garbage is discharged by dumping the garbage storage box B may also be used.

[0020] As shown in Figure 1, a garbage dump box T is connected to the rear opening of the garbage collection box B. The garbage dump box T is pivoted by a hinge H provided at the upper rear part of the garbage collection box B. This allows the garbage dump box T to rotate vertically around the hinge H, enabling it to open and close relative to the garbage collection box B. The hinges H are provided on both the left and right ends of the garbage collection box B.

[0021] The garbage bin T is configured to rotate between a closed position (solid line in FIG. 1) in which it closes the rear end opening of the garbage collection box B, and an open position (chain double-dashed line in FIG. 1) in which it opens the rear end opening and allows garbage to be discharged. In FIG. 2, a pair of swing cylinders 26, located on both the left and right ends of the garbage bin T, are attached at their upper ends to the garbage collection box B and at their lower ends to the garbage bin T. When the swing cylinders 26 are extended, the garbage bin T is rotated upward (opened) (chain double-dashed line in FIG. 1), and when they are retracted, the garbage bin T is rotated downward (closed) (solid line in FIG. 1).

[0022] A trash inlet T1 through which trash is dropped is formed at the rear of the trash bin T, and a lid T5 is provided to open and close the trash inlet T1 by sliding it up and down. Also, an opening T2 is provided at the front lower part of the trash bin T to store the trash in the trash storage box B.

[0023] Referring to FIG. 1, the loading device 2 provided in the garbage bin T will be described. First, guide rails 23 extending diagonally up and down are provided on the left and right side walls T3 of the garbage bin T, and two pairs of rollers 25 (one pair each) attached to a slider 20 can move diagonally up and down within the guide rails 23. The slider 20 is formed by connecting left and right members having a side shape as shown in FIG. 1 with a plate or the like (not shown) extending in the vehicle width direction to form an integrated unit. A push plate 21 is rotatably attached to the lower end of the slider 20 via a pin 20a. The push plate 21 is also formed by connecting left and right members having a side shape as shown in FIG. 1 with a plate or the like (not shown) extending in the vehicle width direction to form an integrated unit. Meanwhile, the cylinder side end of the push cylinder 22 is attached to the left and right side walls T3 with a pin 22a, and the piston side end is connected to the upper end of the slider 20 with a pin 20b. On the other hand, the cylinder side end of the press cylinder 24 is connected to the push plate 21 by a pin 24a, and the piston side end is connected to the upper end of the slider 20 by a pin 20b. The slider 20 rises obliquely together with the push plate 21 when the push cylinder 22 is extended, and falls obliquely when the push cylinder 22 is retracted. In addition, the push plate 21 rotates clockwise around the pin 20a when the press cylinder 24 is extended, and rotates counterclockwise when the press cylinder 24 is retracted.

[0024] With the above configuration, the garbage thrown into the garbage drop box T is moved to the rear position by the reversal process of the pusher plate 21, compressed by the primary compression and secondary compression processes, and pushed into the garbage storage box B by the pushing process. This operation constitutes one cycle, and the garbage thrown into the garbage drop box T is loaded into the garbage storage box B. In order to operate each of the above processes sequentially, various sensors (described later) are provided at appropriate locations inside the garbage drop box T to detect the raised and lowered positions of the slider 20 and the rear and front positions of the pusher plate 21, respectively.

[0025] The loading operation will be described in detail below. The loading operation is performed by extending and retracting the push cylinder 22 and the press cylinder 24, and includes a series of steps: an inversion step performed by rotating the push plate 21 backward from the forward position to the rearward position while the slider 20 is held in the raised position; a primary compression step performed by lowering the slider 20 from the raised position to the lowered position while the push plate 21 is held in the rearward position; a secondary compression step performed by rotating the push plate 21 forward from the rearward position to the frontward position while the slider 20 is held in the lowered position; and a pushing step performed by raising the slider 20 from the lowered position to the raised position while the push plate 21 is held in the forward position. By performing this loading operation, the input garbage in the garbage input box T is forcibly pushed into the garbage storage box B.

[0026] In this embodiment, an example of a press type that has a compression stroke in the garbage loading operation is shown, but this is not limited to this, and a rotary plate type that loads garbage using a rotary plate and a push plate may also be used.

[0027] 3, a locking device 3 for fastening a garbage bin T to the vehicle body frame F is provided at the rear of the vehicle body frame F. This locking device 3 includes a hook 30 rotatably attached to the vehicle body frame F, a lock pin 31 fixed to the garbage bin T, a lock cylinder 32 for rotating the hook 30, and a connecting mechanism 33 for connecting the hook 30 and the lock cylinder 32.

[0028] The hook 30 is rotatably attached via a pin 30a to a bracket 34 fixed to the underside of the body frame F. A lock pin 31 is fixed to the front lower part of the trash bin T, and the tip of the hook 30 is releasably engaged with the lock pin 31 from below. The cylinder side end of the lock cylinder 32 is attached to the bottom of the trash collection bin B. The piston side end of the lock cylinder 32 is attached to a connecting mechanism 33.

[0029] With the above configuration, when the lock cylinder 32 is extended from the locked state shown in Fig. 3, the hook 30 rotates clockwise in Fig. 3 around the pin 30a. This disengages the hook 30 from the lock pin 31, and the trash bin T enters an unlocked state. When the lock cylinder 32 is retracted from this unlocked state, the hook 30 rotates counterclockwise in Fig. 3 around the pin 30a, and the hook 30 engages with the lock pin 31, and the trash bin T is locked with the opening T2 closed.

[0030] As described above, the refuse collection vehicle G is equipped with the discharge cylinder 12, push cylinder 22, press cylinder 24, swing cylinder 26, lock cylinder 32, etc. as actuators that operate each part.

[0031] The external operating unit provided on the garbage bin T will be described with reference to Figure 2. Switch boxes 61 and 62 are provided at the rear of both the left and right side walls T3 of the garbage bin T. A selection switch 61a is provided on the side of the switch box 61 to select either the "continuous cycle" or "single cycle" operation mode for the operation of the loading device 2, and a loading switch 61b is provided on the front to start the loading operation in each operation mode, and a stop switch 61c is provided to stop the continuous cycle operation. The other switches are switches to be used only in emergencies, and detailed description thereof will be omitted. A stop switch 61c is also provided on the right switch box 62.

[0032] FIG. 4 is a perspective view of the refuse collection vehicle G seen from the rear, and schematically illustrates the electrical wiring arrangement. The control device 60 controls the actuators 12, 22, 24, 26, and 32 in response to commands from switch boxes 61 and 62 and an operating device (not shown) provided in the driver's cab C. The control device 60 also receives signals from various sensors for determining the operating states of the actuators 12, 22, 24, 26, and 32. In this specification, the term "electrical wiring" includes electrical signal lines connecting the switch boxes 61 and 62 to the control device 60 in order to operate the actuators 12, 22, 24, 26, and 32, and sensor lines connecting the control device 60 to various sensors for determining the operating states of the actuators 12, 22, 24, 26, and 32. The term "electrical wiring" also includes not only cables but also cylindrical piping through which the cables pass. Examples of sensors for determining the operating states of the actuators 12, 22, 24, 26, and 32 include, but are not limited to, a push-in completion position detection sensor 71, a reverse completion position detection sensor 72, a primary compression completion position detection sensor 73, a secondary compression completion position detection sensor 74, a lock-closed detection sensor 75, and a drop box closed detection sensor 76. In addition, in the case of an electric vehicle, the "electrical wiring" may include high-voltage wiring that connects the battery 29, which will be described later, and the driving motor.

[0033] The control device 60 is disposed between the driver's cab C and the trash container B. The upper cord 60a extending from the control device 60 to the switch boxes 61 and 62 passes through the front wall B4 of the trash container B, the top wall B2 of the trash container B, the hinge H, the top wall T4 of the trash container T, and the side wall T3 of the trash container T, in that order. Here, the upper cord 60a passing through the front wall B4 and the top wall B2 of the trash container B and the top wall T4 and the side wall T3 of the trash container T means that the upper cord 60a not only extends along the outer surfaces of these walls, but also extends through the interior of hollow reinforcing materials that reinforce these walls. Furthermore, the upper cord 60a passing through the hinge H means that it passes through the space between the left and right hinges H as shown in FIG. 4. In the trash container B, the upper cord 60a is fixed to the top wall B2 of the trash container B. The upper cord 60a is branched and connected to various sensors 71, 72, 73, 74, and 76 for detecting the operating states of the actuators 22, 24, and 26, respectively.

[0034] The lower cord 60b, which extends from the control device 60 to the sensor 75 for monitoring the operating state of the actuator 32, passes through the front wall B4 of the trash receptacle B and the bottom wall B1 of the trash receptacle B in that order. Here, the lower cord 60b passing through the front wall B4 and bottom wall B1 of the trash receptacle B means that the lower cord 60b not only extends along the outer surfaces of these walls, but also extends through the interior of hollow reinforcing materials that reinforce these walls. In the trash receptacle B, the lower cord 60b is fixed to the bottom wall B1 of the trash receptacle B. Note that in the trash receptacle B, the lower cord 60b may also be fixed to the lower frame B5 of the trash receptacle B.

[0035] The refuse collection vehicle G also includes a hydraulic pump 40 that supplies hydraulic oil to each of the actuators 12, 22, 24, 26, and 32. As shown in Fig. 1, the hydraulic pump 40 is disposed, for example, below and behind the driver's cab C, and is mounted on the vehicle body frame F. The refuse collection vehicle G also includes a control valve 41 that adjusts the hydraulic pressure of the hydraulic oil supplied from the hydraulic pump 40 to each of the actuators 12, 22, 24, 26, and 32. The hydraulic pump 40 supplies hydraulic oil to the control valve 41.

[0036] The refuse collection vehicle G may be equipped with an electric motor 27 for driving a hydraulic pump 40. The electric motor 27 is disposed, for example, below the driver's cab C and is mounted on the vehicle body frame F. A gear box 28 may be interposed between the electric motor 27 and the hydraulic pump 40.

[0037] The refuse collection vehicle G may be equipped with a battery 29 that supplies power to the electric motor 27. The battery 29 is, for example, disposed below the refuse collection box B and mounted on the vehicle body frame F. The battery 29 also supplies power to a traveling motor (not shown) that drives the vehicle body frame F. In other words, the refuse collection vehicle G may be an electric vehicle that runs on power from the battery 29.

[0038] Figure 5 is a front view of the garbage collection box B seen from the front side. Figure 6 is a side view of the garbage collection box B seen from the left side. The garbage collection vehicle G is equipped with a hydraulic pump 40, a control valve 41, an oil tank 42, a suction hose 43 connecting the oil tank 42 and the hydraulic pump 40, and a delivery hose 44 connecting the control valve 41 and the hydraulic pump 40.

[0039] The hydraulic pump 40 has a suction port 40a that draws in hydraulic oil and a discharge port 40b that discharges the drawn hydraulic oil. A suction hose 43 is connected to the suction port 40a. A delivery hose 44 is connected to the discharge port 40b. The discharge port 40b is located above the suction port 40a.

[0040] The oil tank 42 also includes an oil supply port 42a to which the suction hose 43 is connected, and a return port (not shown) to which a return hose (not shown) is connected.

[0041] The hydraulic pump 40 and the oil tank 42 are disposed to the right of the center position CE in the vehicle width direction. The suction port 40a of the hydraulic pump 40 and the oil supply port 42a of the oil tank 42 face leftward, allowing the suction hose 43 to be routed in a U-shape.

[0042] The suction hose 43 has a generally U-shape overall. The suction hose 43 includes a U-shaped pipe 45 and a flexible hose 46. One end 45a of the U-shaped pipe 45 is connected to the suction port 40a of the hydraulic pump 40, and the other end 45b is connected to the flexible hose 46. The U-shaped pipe 45 extends leftward from the one end 45a, then curves and extends rightward to reach the other end 45b. As a result, the U-shaped pipe 45 has a left end 45c. A plane that passes through the left end 45c of the U-shaped pipe 45 and extends in the up-down direction and the fore-and-aft direction of the vehicle is set as a reference plane P. In other words, it can be said that the left end 45c of the suction hose 43 is in contact with the reference plane P. 5 and 6, when viewed in the vertical direction (plan view), the hydraulic pump 40, oil tank 42, and suction hose 43 are disposed between the driver's cab C and the garbage collection box B, to the right of a predetermined reference plane P. This makes it possible to ensure space for loading equipment between the driver's cab C and the garbage collection box B, to the left of the predetermined reference plane P. In this specification, the term "loaded equipment" includes items loaded on the garbage collection vehicle G other than the hydraulic pump 40, oil tank 42, and suction hose 43, and is a concept that includes, for example, accessories such as a spare tire and a basket, as well as the aforementioned electrical wiring (cables, sensor wires, high-voltage wiring, etc.).

[0043] Figure 7 is a left side view showing a schematic diagram of the arrangement of hydraulic piping and electrical wiring of a garbage collection vehicle G. In Figure 7, hydraulic piping is shown by solid lines, and electrical wiring is shown by dashed lines (the same applies to Figures 8 and 9). The garbage collection vehicle G is equipped with hydraulic piping 70a and 70b between the actuators 12, 22, 24, 26, and 32 and the control valve 41. As shown in Figure 7, the hydraulic piping 70a and 70b include an upper hydraulic piping 70a arranged above the garbage collection box B and a lower hydraulic piping 70b arranged below the garbage collection box B.

[0044] 8 and 9 are plan views of the garbage collection vehicle G, and show the layout of the hydraulic piping and electrical wiring. However, for ease of explanation, Fig. 8 shows only the upper hydraulic piping 70a and upper cord 60a arranged at the top of the garbage collection box B, and Fig. 9 shows only the lower hydraulic piping 70b and lower cord 60b arranged at the bottom of the garbage collection box B.

[0045] As shown in Fig. 8, the upper hydraulic piping 70a includes a hydraulic piping 22p between the push cylinder 22 and the control valve 41, a hydraulic piping 24p between the press cylinder 24 and the control valve 41, and a hydraulic piping 26p between the swing cylinder 26 and the control valve 41. Note that in Fig. 8, the upper cord 60a is connected only to the switch box 61, but in reality, as described above, it is also connected to the switch box 62 and various sensors 71, 72, 73, 74, 76, etc.

[0046] In the garbage collection box B, the upper hydraulic piping 70a is fixed to the right of the reference plane P, and the upper cord 60a is fixed to the left of the reference plane P. The upper hydraulic piping 70a and the upper cord 60a are fixed to the garbage collection box B, for example, via a bracket. Note that the upper hydraulic piping 70a and the upper cord 60a are fixed to the top of the garbage collection box B, but the top of the garbage collection box B includes not only the top wall B2 but also the top of the side wall B3. By arranging the upper hydraulic piping 70a and the upper cord 60a on opposite sides of the reference plane P, it is possible to prevent the pulsation of the upper hydraulic piping 70a from coming into contact with the upper cord 60a.

[0047] 9, the lower hydraulic piping 70b includes a hydraulic piping 32p between the lock cylinder 32 and the control valve 41. The lower hydraulic piping 70b may also include a hydraulic piping (not shown) between the discharge cylinder 12 and the control valve 41. In FIG. 9, the lower cord 60b is connected only to the lock-closed detection sensor 75, but it may also be connected to other sensors.

[0048] In the garbage collection box B, the lower hydraulic piping 70b is fixed to the right of the reference plane P, and the lower cord 60b is fixed to the left of the reference plane P. The lower hydraulic piping 70b and the lower cord 60b are fixed to the garbage collection box B, for example, via a bracket. Note that the lower hydraulic piping 70b and the lower cord 60b are fixed to the lower part of the garbage collection box B, but the lower part of the garbage collection box B includes not only the bottom wall B1 but also the lower part of the side wall B3 and the lower frame B5. By arranging the lower hydraulic piping 70b and the lower cord 60b on opposite sides of the reference plane P, it is possible to prevent the pulsation of the lower hydraulic piping 70b from coming into contact with the lower cord 60b.

[0049] [1] As described above, the vehicle (in this embodiment, a garbage collection vehicle G) comprises, as in this embodiment, a driver's cab C, a vehicle body frame F extending rearward from the lower part of the driver's cab C, mounted objects (in this embodiment, a garbage collection box B and a garbage drop box T) arranged above the vehicle body frame F, actuators 12, 22, 24, 26, 32 for driving the mounted objects (in this embodiment, the garbage collection box B and the garbage drop box T), a control valve 41 for adjusting the hydraulic pressure of the hydraulic oil supplied to the actuators 12, 22, 24, 26, 32, a hydraulic pressure generating source (in this embodiment, a hydraulic pump 40) for supplying the hydraulic oil to the control valve 41, and an oil storage tank for storing the hydraulic oil. The vehicle is preferably equipped with an oil tank 42, and a hydraulic hose (in this embodiment, a suction hose 43) connecting the hydraulic generating source (in this embodiment, a hydraulic pump 40) and the oil tank 42, and when viewed in the vertical direction, the hydraulic generating source (in this embodiment, the hydraulic pump 40), the oil tank 42, and the hydraulic hose (in this embodiment, the suction hose 43) are positioned between the driver's cab C and the mounted object (in this embodiment, a garbage collection box B and a garbage drop box T) and on one side in the vehicle width direction (in this embodiment, the right side) of a predetermined reference plane P extending in the vertical direction and the fore-and-aft direction of the vehicle.

[0050] According to this configuration, the hydraulic pump 40, oil tank 42, and suction hose 43 are positioned on one side of the vehicle width direction (in this embodiment, the right side) of a predetermined reference plane P between the driver's cab C and the garbage collection box B, so that space can be secured for loading equipment on one side of the vehicle width direction (in this embodiment, the left side) of the predetermined reference plane P.
