[0018] The drive battery 32 includes a first battery 32F located at the front of the vehicle and a second battery 32R located at the rear of the vehicle.

[0019] The first battery 32F is located below the platform 26. The first battery 32F is positioned in the center in the vehicle width direction.

[0020] The second battery 32R is positioned on the opposite side in the vehicle width direction relative to the center in the vehicle width direction. Specifically, the second battery 32R is located on the opposite side in the vehicle width direction relative to the pair of side members 21. The longitudinal position of the second battery 32R is behind the front wheels 23 and in front of the rear wheels 24.

[0021] The work vehicle 10 is equipped with electric components 33. The electric components 33 include an electric motor for tilting the dump body, an electric motor for controlling the brake pump, and the like.

[0022] The electric component 33 is positioned on one side in the vehicle width direction relative to the center in the vehicle width direction. Specifically, the electric component 33 is positioned on one side in the vehicle width direction relative to the pair of side members 21. The electric component 33 is positioned at the rear of the vehicle. Specifically, the longitudinal position of the electric component 33 is behind the front wheels 23 and in front of the rear wheels 24.

[0023] The work vehicle 10 is equipped with an oil cooler 41.

[0024] The oil cooler 41 is located on the platform 26 on the other side in the vehicle width direction from the cab 28. Specifically, the oil cooler 41 is positioned within a range that includes the center of the work vehicle 10 in the vehicle width direction. The oil cooler 41 has a shape in which the dimensions in the vehicle width direction are larger than the dimensions in the vehicle longitudinal direction.

[0025] The oil cooler 41 is air-cooled and includes a fan (not shown). The oil cooler 41 cools the heat from the hydraulic fluid of the hydraulic retarder brake and the hydraulic fluid of the hydraulic circuit used to tilt the dump body by air passing through the oil cooler 41 in the front-rear direction.

[0026] The work vehicle 10 is equipped with a converter 42.

[0027] The converter 42 is a unit that integrates multiple converters and a cabinet that supports them. The converter 42 converts power between the drive battery 32 and the drive motor 31. The converter 42 also converts power between the drive battery 32 and other devices.

[0028] The converter 42 is positioned on the platform 26. The converter 42 is positioned on the other side in the vehicle width direction relative to the oil cooler 41. Specifically, the converter 42 is located at the other end of the platform 26 in the vehicle width direction.

[0029] The converter 42 has a shape in which its dimensions in the vehicle's longitudinal direction are greater than its dimensions in the vehicle's width direction. The front end of the converter 42 is located further forward than the front end of the oil cooler 41.

[0030] The work vehicle 10 is equipped with temperature control devices 43L and 43R.

[0031] The temperature control devices 43L and 43R are devices that manage the temperature of the drive battery 32, and are specifically also called BTMS (Battery Thermal Management System). The temperature control devices 43L and 43R are liquid-cooled and circulate coolant to adjust the temperature of the drive battery 32.

[0032] Two temperature control devices 43L and 43R are provided. The two temperature control devices 43L and 43R are arranged side by side in the vehicle width direction. Specifically, the two temperature control devices 43L and 43R are positioned at the same location in the front-rear and height directions, but at different locations in the width direction.

[0033] The temperature control devices 43L and 43R are positioned on the platform 26, on one side in the vehicle width direction from the converter 42 and on the other side in the vehicle width direction from the cab 28. An entrance / exit is provided in the side wall on the other side in the vehicle width direction of the cab 28, but this entrance / exit cannot be used in relation to the temperature control devices 43L and 43R. The cab 28 does not necessarily have an entrance / exit in the side wall on the other side in the vehicle width direction. Access to and from the cab 28 is through an entrance / exit provided on one side in the vehicle width direction of the cab 28.

[0034] The temperature control devices 43L and 43R are positioned forward of the oil cooler 41 such that at least a portion of them overlaps with at least a portion of the oil cooler 41 in the vehicle width direction. Specifically, the temperature control device 43L on one side in the vehicle width direction overlaps entirely with a portion of the oil cooler 41 in the vehicle width direction. The temperature control device 43R on the other side in the vehicle width direction overlaps partially with a portion of the oil cooler 41 in the vehicle width direction.

[0035] The temperature control devices 43L and 43R have a roughly rectangular parallelepiped shape. Of the front-to-back, width, and height dimensions, the height dimension of the temperature control devices 43L and 43R is the smallest. The height dimension of the temperature control devices 43L and 43R is smaller than the height dimension of the oil cooler 41.

[0036] At least a portion of the temperature control devices 43L and 43R overlaps with at least a portion of the converter 42 in the longitudinal direction of the vehicle. Specifically, the rear portion of the temperature control devices 43L and 43R overlaps with the front portion of the converter 42 in the longitudinal direction of the vehicle.

[0037] The work vehicle 10 is equipped with a power distribution device 44.

[0038] The power distribution device 44, also known as a PDU (Power Distribution Unit), distributes power from the drive battery 32 to the drive motor 31, various electric motors, and the like.

[0039] The power distribution device 44 is positioned directly below the temperature control devices 43L and 43R. Although not shown in the diagram, specifically, the power distribution device 44 is positioned directly below the temperature control device 43L on one side in the vehicle width direction. The power distribution device 44 is positioned so that it can be operated by workers on the platform 26.

[0040] The work vehicle 10 is equipped with radiators 51L and 51R positioned in front of the first battery 32F.

[0041] Specifically, the radiators 51L and 51R include a one-side radiator 51L disposed at a position offset from the center in the vehicle width direction to one side in the vehicle width direction, and an other-side radiator 51R disposed at a position offset from the center in the vehicle width direction to the other side in the vehicle width direction. Each of the radiators 51L and 51R includes a radiator core and a plurality of cooling fans (not shown). The cooling fans are disposed behind the radiator core. Each of the radiators 51L and 51R has a rectangular shape with the longitudinal direction extending along the vertical direction of the vehicle when viewed from the front of the vehicle. A refrigerant (cooling water) cooled by the radiators 51L and 51R is configured to cool the drive motor 31, the motor of a hydraulic pump, the motor of an oil cooler 41, and the like.

[0042] As shown in FIG. 1 and FIG. 2, the work vehicle 10 includes a power feeding port 61 for feeding power to a driving battery 32, and a charging cable 62 connecting the power feeding port 61 and the driving battery 32.

[0043] The power feeding port 61 is disposed at a position where a power feeding operation can be performed by an operator standing on the front side of the work vehicle 10. The power feeding port 61 is disposed on one side in the width direction with respect to the center in the vehicle width direction. Specifically, the power feeding port 61 is disposed on the outer side in the vehicle width direction (one side in the vehicle width direction) relative to the radiators 51L and 51R.

[0044] The charging cable 62 is routed such that a part thereof overlaps the air inflow region of the one-side radiator 51L when viewed from the front of the vehicle, and passes through the front of the one-side radiator 51L. Said part of the charging cable 62 crosses the front of the one-side radiator 51L in the vehicle width direction. Further, the charging cable 62 is passed through the space formed between the one-side radiator 51L and the other-side radiator 51R in the front-rear direction of the vehicle, and is connected to a power distribution device 44 and the like.

[0045] <Functions and Effects> Next, the functions and effects of the present embodiment will be described.

[0046] In the present embodiment, the work vehicle 10 includes a drive motor 31 that generates driving force, and a driving battery 32 that supplies electric power to the drive motor 31.

[0047] Incidentally, when the work vehicle 10 includes only a battery disposed at the front part of the vehicle as the driving battery 32 (see Patent Document 1), a sufficient size of the battery cannot be ensured due to restrictions on the installation space, and as a result, it may become difficult to satisfy the required traveling performance. Therefore, in the present embodiment, as shown in FIG. 1, FIG. 3, and the like, the driving battery 32 includes a first battery 32F and a second battery 32R. For this reason, compared to a case where the driving battery 32 includes only the first battery 32F, it is easier to ensure the size of the driving battery 32. As a result, traveling performance can be improved.

[0048] Further, in the present embodiment, the first battery 32F is positioned forward of the driving motor 31 and aligned with the driving motor 31 in the front-rear direction. For this reason, by aligning the first battery 32F and the driving motor 31 in the front-rear direction, it is possible to suppress displacement of the center of gravity of the first battery 32F and the center of gravity of the driving motor 31 in the vehicle width direction, thereby improving the weight balance in the vehicle width direction.

[0049] Further, in the present embodiment, the second battery 32R is aligned with the driving motor 31 in the vehicle width direction. For this reason, by aligning the second battery 32R and the driving motor 31 in the vehicle width direction, it is possible to suppress displacement of the center of gravity of the second battery 32R and the center of gravity of the driving motor 31 in the front-rear direction, thereby improving the weight balance in the front-rear direction.

[0050] Further, in the present embodiment, as shown in FIG. 1, the work vehicle 10 includes an electric component 33. Incidentally, if the second battery 32R and the electric component 33 were disposed on the same side with respect to the center in the vehicle width direction, it may become difficult to achieve left-right weight balance of the work vehicle 10. Therefore, in the present embodiment, as shown in FIG. 1, the second battery 32R and the electric component 33 are aligned in the vehicle width direction with the driving motor 31 interposed therebetween. For this reason, it is possible to easily achieve left-right weight balance of the work vehicle 10.

[0051] Furthermore, in this embodiment, the work vehicle 10 is equipped with an oil cooler 41. However, if the oil cooler 41 were to be placed below the platform 26, there is a possibility that sufficient space could not be secured for the first battery 32F, which is located below the platform 26. Therefore, in this embodiment, as shown in Figure 4, the oil cooler 41 is placed on the platform 26. This makes it easier to secure space for the first battery 32F below the platform 26.

[0052] Furthermore, in this embodiment, as shown in Figure 1, the work vehicle 10 includes a cab 28 provided on a platform 26 and a converter 42 that converts power between a drive battery 32 and a drive motor 31. The cab 28 is located on one side in the vehicle width direction relative to the center in the vehicle width direction, and the converter 42 and oil cooler 41 are located on the other side in the vehicle width direction relative to the cab 28 on the platform 26. However, if the oil cooler 41 and converter 42, which are located to the side of the cab 28, were to be arranged side by side in the front-rear direction, the view from the cab 28 to the other side in the vehicle width direction may be obstructed by the oil cooler 41 or converter 42. Therefore, in this embodiment, as shown in Figure 1, the converter 42 and oil cooler 41 are arranged side by side in the vehicle width direction. As a result, deterioration of visibility when looking from the cab 28 to the other side in the vehicle width direction can be suppressed.

[0053] Incidentally, the weight of the oil cooler 41 tends to be greater than that of the converter 42. Therefore, depending on the placement of the oil cooler 41, the left-right weight balance of the work vehicle 10 may be disrupted. In this embodiment, as shown in Figure 1, the oil cooler 41 is placed between the converter 42 and the cab 28. This makes it easier to balance the left-right weight of the work vehicle 10.

[0054] Furthermore, in this embodiment, as shown in Figure 1, the work vehicle 10 is positioned on the platform 26 and is equipped with temperature control devices 43L and 43R for managing the temperature of the drive battery 32. Incidentally, the height of the temperature control devices 43L and 43R can be made smaller than that of the oil cooler 41. Here, if the oil cooler 41 were to be positioned in front of the temperature control devices 43L and 43R, the view from the cab 28 looking to the other side in the vehicle width direction may be obstructed and worsened by the oil cooler 41. Therefore, in this embodiment, as shown in Figure 1, in a plan view, at least a part of the temperature control devices 43L and 43R are aligned with at least a part of the oil cooler 41 in the vehicle width direction and are positioned in front of the oil cooler 41. As a result, the deterioration of the view from the cab 28 looking to the other side in the vehicle width direction can be suppressed.

[0055] However, the dimensions of the converter 42 may increase in the longitudinal direction of the vehicle. In this case, it is difficult to find space on the platform 26 to place other devices in front of or behind the converter 42. Therefore, in this embodiment, as shown in Figure 1, at least a portion of the temperature control devices 43L and 43R are aligned with at least a portion of the converter 42 in the vehicle width direction in a plan view, and are positioned on one side of the converter 42 in the vehicle width direction. As a result, when the dimensions of the converter 42 increase in the longitudinal direction of the vehicle, the converter 42 and the temperature control devices 43L and 43R can be efficiently arranged.

[0056] Furthermore, in this embodiment, the work vehicle 10 is equipped with a power supply port 61 for supplying power to the drive battery 32, and a charging cable 62 connecting the power supply port 61 and the drive battery 32. However, since high voltage and high current flow through the cable connecting the battery and the charging port in order to perform rapid charging, heat generation of the cable becomes a problem. Therefore, in this embodiment, as shown in Figure 2, the charging cable 62 is routed to pass in front of the radiators 51L and 51R such that a portion of it overlaps with the air intake area of ​​the radiators 51L and 51R when viewed from the front of the vehicle. As a result, the charging cable 62 can be cooled by the air drawn into the radiators 51L and 51R.

[0057] Incidentally, the air that passes through the radiators 51L and 51R can become hot. Therefore, if the air that has passed through the radiators 51L and 51R hits the first battery 32F, the temperature of the first battery 32F may rise too high. To address this, in this embodiment, as shown in Figure 1, the radiators 51L and 51R consist of a one-side radiator 51L positioned on one side in the vehicle width direction and a other-side radiator 51R positioned on the other side in the vehicle width direction. In a front view, at least a portion of the first battery 32F is located between the one-side radiator 51L and the other-side radiator 51R. Therefore, at least a portion of the battery does not overlap with the radiators and is not exposed to hot air. This helps to suppress the temperature rise.

[0058] Furthermore, in this embodiment, the first battery 32F is located between the one-sided radiator 51L and the other-sided radiator 51R. Therefore, it is possible to suppress the air that has passed through the radiators 51L and 51R from hitting the first battery 32F.

[0059] Furthermore, in this embodiment, the charging cable 62 is routed in the vehicle's longitudinal direction through the space formed between one radiator 51L and the other radiator 51R. Therefore, when the radiators 51L and 51R consist of one radiator 51L and the other radiator 51R, the charging cable 62 can be efficiently routed.

[0060] While preferred embodiments of the present disclosure have been described above, the present disclosure is not limited to those described above.

[0061] In the above embodiment, the portion of the work vehicle 10 in front of the rear end of the front wheel 23 is defined as the front of the vehicle, and the portion behind it is defined as the rear of the vehicle. However, the front and rear of the vehicle in this disclosure are not limited to this definition and are relative concepts.

[0062] In the above embodiment, the work vehicle 10 is a dump truck, but the work vehicle of this disclosure is not limited to this.

[0063] In the above embodiment, the work vehicle 10 does not have an engine such as a diesel engine or a hydrogen engine, but the work vehicle of this disclosure is not limited to this. The work vehicle of this disclosure may have an engine in addition to a drive motor and a drive battery.

[0064] In the above embodiment, the electric component 33 is positioned on one side in the vehicle width direction, which is on the same side as the cab 28 with respect to the center in the vehicle width direction. However, the disclosure is not limited thereto. The electric component 33 may be positioned on the other side in the vehicle width direction, which is on the opposite side of the cab 28 with respect to the center in the vehicle width direction.

[0065] In the above embodiment, the oil cooler 41 is positioned closer to the center in the vehicle width direction than the converter 42, but the disclosure is not limited thereto. The converter 42 may be positioned closer to the center in the vehicle width direction than the oil cooler 41.

[0066] In the above embodiment, the radiators 51L and 51R include a one-side radiator 51L positioned offset to one side in the vehicle width direction from the center in the vehicle width direction, and a other-side radiator 51R positioned offset to the other side in the vehicle width direction from the center in the vehicle width direction. However, the radiators of this disclosure are not limited to this.

[0067] In the above embodiment, the charging cable 62 is routed so that, in a front view of the vehicle, a portion of it overlaps with the air intake area of ​​the one-side radiator 51L, passing in front of the said one-side radiator 51L. However, the charging cable of this disclosure is not limited to this. The charging cable may also be routed so that, in a front view of the vehicle, a portion of it overlaps with the air intake area of ​​the other-side radiator 51R, passing in front of the said other-side radiator 51R.
