Description

[Technical field]

[0001] The present invention relates to an electric work vehicle including a battery, a motor driven by power supplied from the battery, and a traveling device driven by the motor. [Background technology]

[0002] The work vehicle described in Patent Document 1 (referred to as a "tractor" in Patent Document 1) is equipped with an engine and a traveling device (referred to as "front wheels" and "rear wheels" in Patent Document 1) driven by the engine. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-69926 A Summary of the Invention [Problem to be solved by the invention]

[0004] It is conceivable to provide a battery and a motor instead of the engine in the work vehicle described in Patent Document 1. This would allow the vehicle to travel without emitting exhaust gas.

[0005] Furthermore, in the work vehicle described in Patent Document 1, it is conceivable to provide a hydraulic pump that is driven by the motor and supplies oil to the operating mechanism of the working device.

[0006] However, in this case, depending on the arrangement of the motor and the hydraulic pump, it is conceivable that the power transmission path from the motor to the hydraulic pump will be relatively long, resulting in a relatively large power transmission loss in this power transmission path.

[0007] Furthermore, if a dedicated member is provided to support the hydraulic pump, the manufacturing costs tend to increase.

[0008] An object of the present invention is to provide an electric work vehicle in which the power transmission loss from the motor to the hydraulic pump is relatively small and which can be manufactured at low costs. [Means for solving the problem]

[0009] The present invention is characterized in that it includes a working device, a battery, a motor driven by power supplied from the battery, a traveling device driven by the motor, and a hydraulic pump driven by the motor and supplying oil to an operating mechanism of the working device; and a support member connected to the motor, wherein an output shaft of the motor extends in a front-rear direction of the electric work vehicle, and the motor and the hydraulic pump are disposed adjacent to each other. The reason is that it is being done.

[0010] According to the present invention, the motor and the case are relatively close to each other. Also, the hydraulic pump and the case are relatively close to each other. Therefore, the motor and the hydraulic pump are relatively close to each other. Therefore, the power transmission path from the motor to the hydraulic pump is relatively short. As a result, the power transmission loss from the motor to the hydraulic pump is relatively small.

[0011] Furthermore, with the present invention, the hydraulic pump is supported by the case, so there is no need to provide a dedicated member for supporting the hydraulic pump, which tends to reduce manufacturing costs compared to when a dedicated member is provided for supporting the hydraulic pump.

[0012] In other words, the present invention makes it possible to realize an electric work vehicle in which the power transmission loss from the motor to the hydraulic pump is relatively small and which can be manufactured at low costs.

[0013] Further, in the present invention, The hydraulic pump further includes a transmission device that transmits power from the motor to the hydraulic pump, the transmission device being located between the motor and the actuating mechanism. It is preferable to do so.

[0014]

[0015]

[0016] Further, in the present invention, The hydraulic pump is supported by the support member, and the hydraulic pump, the motor, and the support member are located forward of the driving unit. It is preferable to do so.

[0017]

[0018]

[0019] Further, in the present invention, The support member is plate-shaped, and the hydraulic pump is in contact with the surface of the support member that is in contact with the motor. It is preferable to have

[0020]

[0021]

[0022]

[0023] Further, in the present invention, The output shaft of the motor and the input shaft of the hydraulic pump both extend in the front-rear direction of the electric work vehicle. It is preferable to do so.

[0024]

[0025]

[0026] Further, in the present invention, The output shaft of the motor and the input shaft of the hydraulic pump both pass through the support member. It is preferable to do so.

[0027]

[0028] Further, in the present invention, The output shaft of the motor and the input shaft of the hydraulic pump are both parallel to the front-rear direction of the electric work vehicle. It is preferable to do so.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] The embodiment of the present invention will be described with reference to the drawings. In the following description, the direction of the arrow F shown in Figures 1 to 3 and 5 is defined as "front", the direction of the arrow B is defined as "rear", the direction of the arrow L shown in Figures 2 and 4 is defined as "left", and the direction of the arrow R is defined as "right". In addition, the direction of the arrow U shown in Figures 1, 3 and 4 is defined as "up", and the direction of the arrow D is defined as "down".

[0032] [Overall configuration of the tractor] As shown in FIG. 1, tractor A (corresponding to the "electric work vehicle" of the present invention) is equipped with left and right front wheels 10 (corresponding to the "running device" of the present invention), left and right rear wheels 11 (corresponding to the "running device" of the present invention), a cover member 12, and a tilling device 13 (corresponding to the "working device" of the present invention).

[0033] The tractor A also has a body frame 2 and a driving section 3.

[0034] The machine body frame 2 is supported by left and right front wheels 10 and left and right rear wheels 11. In addition, the tilling implement 13 is supported at the rear of the machine body frame 2.

[0035] The cover member 12 is disposed at the front of the vehicle body. The driver's section 3 is disposed behind the cover member 12.

[0036] The driving section 3 has a protective frame 30, a driving seat 31, a steering wheel 32, and a floor 33. An operator can sit in the driving seat 31. The operator can then use the driving section 3 to perform various driving operations.

[0037] The left and right front wheels 10 are steered by operating the steering wheel 32. In addition, an operator can place his / her feet on a floor 33 while seated in the driver's seat 31.

[0038] The tractor A also includes a battery 4, a motor M, a transmission T, and a front transmission mechanism FT.

[0039] The battery 4 is housed in the cover member 12. The battery 4 supplies power to the motor M.

[0040] The motor M is disposed below the battery 4. The motor M is driven by electric power supplied from the battery 4. The driving force of the motor M is transmitted to the transmission T.

[0041] The transmission T is disposed rearward of the battery 4 and rearward of the motor M. The front transmission mechanism FT extends forward from the transmission T. The transmission T changes the speed of the driving force received from the motor M and transmits it to the left and right rear wheels 11. The driving force is also transmitted from the transmission T to the left and right front wheels 10 via the front transmission mechanism FT. As a result, the left and right front wheels 10 and the left and right rear wheels 11 are driven.

[0042] That is, the tractor A includes a motor M that is driven by power supplied from a battery 4. The tractor A also includes left and right front wheels 10 and left and right rear wheels 11 that are driven by the motor M.

[0043] Further, the transmission T transmits a part of the driving force received from the motor M to the tillage implement 13. In this way, the tillage implement 13 is driven.

[0044] With the above-described configuration, the tractor A can perform tilling work using the tilling implement 13 while traveling using the left and right front wheels 10 and the left and right rear wheels 11.

[0045] [Configuration of motor and hydraulic pump] 2 and 3, the aircraft frame 2 has left and right main frames 20. The left and right main frames 20 extend in the fore-and-aft direction of the aircraft.

[0046] That is, the tractor A has left and right main frames 20 extending in the fore-and-aft direction of the vehicle body.

[0047] The motor M is disposed at a position sandwiched between the left and right main frames 20.

[0048] As shown in Figures 1 and 2, the tractor A is equipped with a hydraulic pump 60. The hydraulic pump 60 is driven by a motor M. The hydraulic pump 60 also supplies oil to an operating mechanism that operates the tilling implement 13. The tilling implement 13 can be operated by controlling the supply of oil.

[0049] More specifically, the tractor A has a lifting mechanism 36 which is an operating mechanism for the working implement. The hydraulic pump 60 supplies oil to the lifting mechanism 36. This operates the lifting mechanism 36. The operation of the lifting mechanism 36 raises and lowers the tilling implement 13. A drive section of the tilling unit 13a of the tilling implement 13 is connected to a PTO shaft 37 of the tractor A. The tilling unit 13a can perform tilling work using power from the PTO shaft 37.

[0050] That is, the tractor A is driven by a motor M and includes a hydraulic pump 60 that supplies oil to the lifting mechanism 36 of the tilling implement 13.

[0051] As shown in FIGS. 4 and 5, the motor output shaft 40, which is the output shaft of the motor M, is inserted into the first cylindrical shaft 61 and is spline-fitted to the first cylindrical shaft 61.

[0052] 2 and 3, the transmission input shaft 63, which is the input shaft of the speed change device T, has a motor coupling portion 63a. The motor coupling portion 63a is provided on the front end portion of the transmission input shaft 63.

[0053] As shown in FIG. 5, the motor connecting portion 63a is inserted into the first cylindrical shaft 61 and is spline-fitted to the first cylindrical shaft 61.

[0054] With the above-described configuration, the first cylindrical shaft 61 and the power transmission input shaft 63 rotate integrally with the motor output shaft 40. As a result, the power from the motor M is input to the transmission T.

[0055] The motor output shaft 40, the first cylindrical shaft 61, and the transmission input shaft 63 all extend in the fore-and-aft direction of the vehicle body.

[0056] [Case Configuration] 4 and 6, the tractor A is equipped with a transmission device 50. The transmission device 50 transmits power from the motor M to a hydraulic pump 60.

[0057] That is, the tractor A is equipped with a transmission device 50 that transmits power from the motor M to the hydraulic pump 60.

[0058] More specifically, the transmission device 50 has a first gear 51, a second gear 52, a third gear 53, a fourth gear 54, and a fifth gear 55. As shown in Fig. 4, these gears are arranged in the following order from the left side of the aircraft body: first gear 51, second gear 52, third gear 53, fourth gear 54, and fifth gear 55.

[0059] 4 to 6, the first gear 51 is attached to a first cylindrical shaft 61. The first gear 51 rotates integrally with the first cylindrical shaft 61. The first gear 51 and the second gear 52 mesh with each other.

[0060] The second gear 52 and the third gear 53 mesh with each other. The third gear 53 and the fourth gear 54 mesh with each other. The fourth gear 54 and the fifth gear 55 mesh with each other.

[0061] 4 and 6, the fifth gear 55 is attached to the second cylindrical shaft 62. The fifth gear 55 is attached to the second cylindrical shaft 62. The fifth gear 55 rotates integrally with the second cylindrical shaft 62.

[0062] Here, the pump input shaft 41, which is the input shaft of the hydraulic pump 60, is inserted into the second cylindrical shaft 62 and is spline-fitted to the second cylindrical shaft 62. As a result, the second cylindrical shaft 62 and the pump input shaft 41 rotate integrally with the fifth gear 55.

[0063] Incidentally, both the pump input shaft 41 and the second cylindrical shaft 62 extend in the fore-and-aft direction of the aircraft body.

[0064] With the above configuration, power from the motor M is transmitted to the pump input shaft 41 via the motor output shaft 40, the first cylindrical shaft 61, the first gear 51, the second gear 52, the third gear 53, the fourth gear 54, the fifth gear 55, and the second cylindrical shaft 62. This drives the hydraulic pump 60.

[0065] That is, the transmission device 50 is of a gear type.

[0066] 2 to 6, the tractor A includes a case 7. The case 7 houses a first gear 51, a second gear 52, a third gear 53, a fourth gear 54, and a fifth gear 55.

[0067] That is, the tractor A has a case 7 that houses the transmission device 50.

[0068] The case 7 has a first member 71 and a second member 72 adjacent to each other in the front-rear direction of the aircraft. The first member 71 is formed in a vertical plate shape. The first member 71 supports the first cylindrical shaft 61, the second gear 52, the third gear 53, the fourth gear 54, and the second cylindrical shaft 62. The second member 72 is formed in a box shape that is open to the front.

[0069] The first member 71 is located on one side in the front-rear direction of the aircraft with respect to the second member 72. More specifically, the first member 71 is located on the front side with respect to the second member 72.

[0070] 2, 3 and 6, the other end portions of the left and right main frames 20 in the longitudinal direction of the aircraft are connected to one end portion of the first member 71 in the longitudinal direction of the aircraft. More specifically, the rear end portions of the left and right main frames 20 are connected to the front end portion of the first member 71.

[0071] 2 to 6, the second member 72 abuts against the first member 71 from the rear side. The tractor A is equipped with a plurality of motor side fasteners 8 (corresponding to the "fasteners" according to the present invention) and a plurality of pump side fasteners 9. The first member 71 and the second member 72 are connected to each other by the plurality of motor side fasteners 8 and the plurality of pump side fasteners 9.

[0072] Moreover, by removing the multiple motor-side fasteners 8 and the multiple pump-side fasteners 9, the second member 72 can be separated from the first member 71 toward the other side in the fore-and-aft direction of the machine body. More specifically, the second member 72 can be separated from the first member 71 toward the rear.

[0073] That is, the second member 72 is configured to be separable from the first member 71 toward the other side in the longitudinal direction of the aircraft body.

[0074] Each of the motor-side fasteners 8 is formed of a bolt. However, the present invention is not limited to this, and each of the motor-side fasteners 8 may be formed of a bolt and a nut.

[0075] Furthermore, each of the plurality of pump-side fasteners 9 is formed of a bolt. However, the present invention is not limited to this, and each of the plurality of pump-side fasteners 9 may be formed of a bolt and a nut.

[0076] 4, the multiple motor-side fasteners 8 are arranged, in rear view, aligned in the circumferential direction of the motor output shaft 40, which is the output shaft of the motor M, around the motor output shaft 40. Each of the multiple motor-side fasteners 8 extends in the fore-and-aft direction of the aircraft and is inserted from the rear into a corresponding bolt hole.

[0077] In this embodiment, the distances between each motor-side fastener 8 and the motor output shaft 40 are equal to each other. That is, the multiple motor-side fasteners 8 are arranged on a single circumference centered on the motor output shaft 40. However, the present invention is not limited to this. The distances between each motor-side fastener 8 and the motor output shaft 40 may be different from each other.

[0078] The multiple motor-side fasteners 8 will be described in detail below. As shown in Figures 2 to 6, the tractor A has a first fastener 81, a second fastener 82, a third fastener 83, a fourth fastener 84, a fifth fastener 85, and a sixth fastener 86. The first fastener 81, the second fastener 82, the third fastener 83, the fourth fastener 84, the fifth fastener 85, and the sixth fastener 86 are all motor-side fasteners 8.

[0079] Here, the motor M and the hydraulic pump 60 are located on one side in the longitudinal direction of the vehicle body with respect to the first member 71. More specifically, the motor M and the hydraulic pump 60 are located on the front side with respect to the first member 71.

[0080] The motor M also has a flange FG. The flange FG is provided at the rear of the motor M. As shown in Fig. 6, the flange FG is formed in a hexagonal shape when viewed in the front-rear direction.

[0081] 2 and 3, the flange FG abuts against the first member 71 from the front side. The motor-side fasteners 8 are disposed corresponding to six corners of the flange FG.

[0082] More specifically, as shown in Figs. 2 to 6, a first fastener 81 is inserted into a bolt hole in the right corner of the flange FG. A second fastener 82 is inserted into a bolt hole in the lower right corner of the flange FG. A third fastener 83 is inserted into a bolt hole in the lower left corner of the flange FG. A fourth fastener 84 is inserted into a bolt hole in the left corner of the flange FG. A fifth fastener 85 is inserted into a bolt hole in the upper left corner of the flange FG. A sixth fastener 86 is inserted into a bolt hole in the upper right corner of the flange FG.

[0083] With this configuration, each motor-side fastener 8 is provided in a state in which it fastens together the motor M, the first member 71, and the second member 72. And, with this configuration, the case 7 is connected to the motor M.

[0084] With the configuration described above, the first member 71 supports the motor M in a cantilever manner.

[0085] 4, the transmission device 50 passes between the first fastener 81 and the second fastener 82. Here, the first fastener 81 and the second fastener 82 are adjacent to each other in the circumferential direction of the motor output shaft 40.

[0086] In this manner, the transmission device 50 is disposed in a state in which it passes between two motor-side fasteners 8 that are adjacent to each other in the circumferential direction of the motor output shaft 40.

[0087] 6, the hydraulic pump 60 is fixed to the first member 71 by a plurality of pump fixing bolts 14. With this configuration, the first member 71 supports the hydraulic pump 60 in a cantilever manner.

[0088] That is, the hydraulic pump 60 is supported by the case 7. Furthermore, the first member 71 supports the motor M in a cantilever manner, and also supports the hydraulic pump 60 in a cantilever manner.

[0089] 4, the multiple pump side fasteners 9 are arranged around the pump input shaft 41. Furthermore, each of the multiple pump side fasteners 9 extends in the fore-and-aft direction of the aircraft body and is inserted into the corresponding bolt holes from the rear.

[0090] 2 to 6, the tractor A is equipped with a first pump side fastener 91, a second pump side fastener 92, and a third pump side fastener 93. The first pump side fastener 91, the second pump side fastener 92, and the third pump side fastener 93 are all pump side fasteners 9.

[0091] The first pump side fastener 91 is located at the upper right of the pump input shaft 41. The second pump side fastener 92 is located at the lower right of the pump input shaft 41. The third pump side fastener 93 is located at the lower left of the pump input shaft 41.

[0092] [Configuration regarding oil storage and movement] In this embodiment, oil is stored inside the case 7. Oil is also stored inside the transmission T. As shown in FIG. 6, an oil discharge portion 72a is provided at the bottom of the second member 72. During maintenance, the oil stored inside the case 7 can be drained from the oil discharge portion 72a by removing the drain bolt in the oil discharge portion 72a.

[0093] As shown in Figs. 2 to 7, a communicating pipe 15 is connected to the lower part of the second member 72. The communicating pipe 15 connects the second member 72 and the transmission T. The communicating pipe 15 also communicates with the space inside the case 7. The communicating pipe 15 also communicates with the space inside the transmission T. Therefore, the space inside the case 7 and the space inside the transmission T are connected by the communicating pipe 15. This allows oil to move between the space inside the case 7 and the space inside the transmission T.

[0094] As shown in Fig. 7, the tractor A includes a first oil passage 21, a second oil passage 22, a third oil passage 23, a fourth oil passage 24, a fifth oil passage 25, and a lift control valve 64. In Fig. 7, the direction of oil flow is indicated by arrows.

[0095] The first oil passage 21 connects the transmission T and the hydraulic pump 60. The second oil passage 22 connects the hydraulic pump 60 and a lift control valve 64. The third oil passage 23 connects the hydraulic pump 60 and a power steering mechanism (not shown). The fourth oil passage 24 connects the lift control valve 64 and the lift mechanism 36. The fifth oil passage 25 connects the lift control valve 64 and the transmission T.

[0096] The hydraulic pump 60 sucks oil from the space inside the transmission T through the first oil passage 21. That is, the oil that moves from the space inside the case 7 through the communicating pipe 15 to the space inside the transmission T is supplied to the hydraulic pump 60 through the first oil passage 21.

[0097] Here, an oil supply passage SP is formed by the communication pipe 15, the transmission T, and the first oil passage 21. The case 7 and the hydraulic pump 60 are connected by the oil supply passage SP.

[0098] That is, the tractor A is provided with an oil supply passage SP that connects the case 7 and the hydraulic pump 60. Then, the oil stored inside the case 7 is supplied to the hydraulic pump 60 through the oil supply passage SP.

[0099] The hydraulic pump 60 pumps the supplied oil to the second oil passage 22 and the third oil passage 23 . The oil pumped to the second oil passage 22 is supplied to the lift control valve 64. The oil pumped to the third oil passage 23 is supplied to the power steering mechanism. The power steering mechanism is operated by the oil pumped through the third oil passage 23.

[0100] The lift control valve 64 controls the supply of oil to the lift mechanism 36 and the discharge of oil from the lift mechanism 36 .

[0101] When oil is supplied to the lifting mechanism 36 from the lifting control valve 64 via the fourth oil passage 24, the lifting mechanism 36 operates in the upward direction. As a result, the tilling implement 13 is raised.

[0102] Furthermore, the oil is discharged from the lifting mechanism 36 through the fourth oil passage 24, so that the lifting mechanism 36 operates in the downward direction. As a result, the tilling implement 13 is lowered.

[0103] In addition, the lift control valve 64 is configured to allow the oil to be returned to the transmission T via the fifth oil passage 25.

[0104] According to the configuration described above, the motor M and the case 7 are relatively close to each other. Also, the hydraulic pump 60 and the case 7 are relatively close to each other. Therefore, the motor M and the hydraulic pump 60 are relatively close to each other. Therefore, the power transmission path from the motor M to the hydraulic pump 60 is relatively short. As a result, the power transmission loss from the motor M to the hydraulic pump 60 is relatively small.

[0105] Furthermore, with the configuration described above, the hydraulic pump 60 is supported by the case 7. Therefore, there is no need to provide a dedicated member for supporting the hydraulic pump 60. Therefore, manufacturing costs tend to be lower than when a dedicated member is provided for supporting the hydraulic pump 60.

[0106] In other words, with the configuration described above, it is possible to realize a tractor A in which the power transmission loss from the motor M to the hydraulic pump 60 is relatively small and the manufacturing costs are likely to be low.

[0107] It should be noted that the embodiment described above is merely an example, and the present invention is not limited to this, and can be modified as appropriate.

[0108] Other embodiments (1) The arrangement of some or all of the components may be inverted left-right.

[0109] (2) The arrangement of some or all of the members may be reversed in the front-rear direction. For example, the first member 71 may be located rearward relative to the second member 72. The motor M and the hydraulic pump 60 may be located rearward relative to the first member 71. The second member 72 may be configured to be separable from the first member 71 to the front.

[0110] (3) Tractor A may be equipped with an engine and configured as a hybrid.

[0111] (4) The motor M may be disposed at a position other than between the left and right main frames 20. For example, the motor M may be disposed above the left and right main frames 20.

[0112] (5) Various devices such as a fertilizer spreading device, a chemical spreading device, a sowing device, a harvesting device, etc., and working devices such as a loader, a shovel, etc. may be provided instead of the tilling device 13. In this case, the various devices such as the fertilizer spreading device, the chemical spreading device, the sowing device, a harvesting device, etc., and working devices such as a loader, a shovel, etc. correspond to the "working device" according to the present invention.

[0113] (6) The support structure of the motor M does not have to be cantilevered.

[0114] (7) The support structure for the hydraulic pump 60 does not have to be a cantilever structure.

[0115] (8) Case 7 may be formed from a single member.

[0116] (9) In the above embodiment, the motor M is supported by the case 7. However, the present invention is not limited to this, and the case 7 may be supported by the motor M.

[0117] (10) In the above embodiment, the number of motor-side fasteners 8 is six. However, the present invention is not limited to this, and the number of motor-side fasteners 8 may be any number other than six.

[0118] (11) In the above embodiment, the number of pump side fasteners 9 is three. However, the present invention is not limited to this, and the number of pump side fasteners 9 may be any number other than three. [Industrial Applicability]
