Description

Oil Pan of Agricultural Vehicle

The present invention relates to an agricultural work vehicle used to cultivate crops necessary for human life using land.

Agricultural work vehicles are used to cultivate crops necessary for human life by utilizing land. For example, combines, tractors, and rice transplanters are agricultural work vehicles. A combine harvests and threshs crops such as rice, barley, wheat, and soybeans. A tractor uses traction power to perform the work necessary for cultivating crops. A rice transplanter transplants rice seedlings grown in seedbeds or nursery boxes into fields.

These agricultural work vehicles include an engine that generates driving force and an oil pan for storing oil. The oil stored in the oil pan is used for lubricating and cooling the engine.

Hereinafter, an embodiment of an oil pan for an agricultural work vehicle according to the present invention will be described in detail with reference to the attached drawings.

Referring to FIGS. 2 and 3, the oil pan (1) of the agricultural work vehicle according to the present invention is installed in the agricultural work vehicle (100). The agricultural work vehicle (100) is used to cultivate crops necessary for human life using land. For example, the agricultural work vehicle (100) may be a tractor, a combine, a rice transplanter, etc.

Before explaining the oil pan (1) of the agricultural work vehicle according to the present invention, the agricultural work vehicle (100) will be described as follows.

The above agricultural work vehicle (100) may include a vehicle body (110), a driver's seat (120) provided in the vehicle body (110), wheels (130) coupled to the vehicle body (110), and a driving device (140) coupled to the vehicle body (110). The driving device (140) may include an engine (150) coupled to the vehicle body (110), and a transmission (160) coupled to the vehicle body (110).

The above driving device (140) can drive the vehicle body (110). When the driving generated by the engine (150) is transmitted to the wheels (130) after being shifted through the transmission (160), the vehicle body (100) can be driven as the wheels (130) rotate. In this case, the driving speed of the agricultural work vehicle (100) can be changed according to the revolutions per minute (RPM) of the engine (150) and the gear ratio performed by the transmission (160). The agricultural work vehicle (100) can be equipped with a work machine (not shown). The agricultural work vehicle (100) can operate the work machine by using the driving generated and shifted by the engine (150) and the transmission (160).

In such agricultural work vehicles (100), the oil pan (1) of the agricultural work vehicle according to the present invention is responsible for storing oil used for lubrication, cooling, etc. of the engine (150). To this end, the oil pan (1) of the agricultural work vehicle according to the present invention may include a receiving groove (2) and a body (3).

Referring to FIGS. 2 and 3, the receiving groove (2) stores oil. The receiving groove (2) may be formed in the main body (3) so as to penetrate one side of the main body (3). Accordingly, the main body (3) may be formed so that one side is open. The main body (3) may be arranged so that the open one side faces the engine (150). The main body (3) may be arranged on the lower side of a crank case (not shown) of the engine (150). In this case, at least one crank (not shown) coupled to the crank case may be inserted into the receiving groove (2).

Referring to FIGS. 2 to 4, the main body (3) is formed with the receiving groove (2). The main body (3) can implement the overall appearance of the oil pan (1) of the agricultural work vehicle according to the present invention. The main body (3) can be formed so that one side is open by the receiving groove (2). The remaining part of the main body (3) except for one side can be arranged to surround the receiving groove (2). Accordingly, oil can be stored in the receiving groove (2).

The above body (3) may include a plurality of side walls (31).

The above side walls (31) are arranged to surround the side of the receiving groove (2). The side walls (31) are implemented to support oil on the side of the receiving groove (2), thereby allowing oil to be stored in the receiving groove (2).

The above main body (3) may include a first side wall (311) and a second side wall (312).

The first side wall (311) and the second side wall (312) are arranged to be spaced apart from each other in the first axial direction (X-axis direction) among the side walls (31). With respect to the first axial direction (X-axis direction), the receiving groove (2) can be arranged between the first side wall (311) and the second side wall (312). Accordingly, the first side wall (311) and the second side wall (312) are implemented to limit the flowable distance of oil received in the receiving groove (2) with respect to the first axial direction (X-axis direction), thereby allowing oil to be stored in the receiving groove (2).

The first side wall (311) may include a first inner wall (311a) arranged to face inward, and a first outer wall (311b) arranged to face outward. The inner side refers to the receiving groove (2) side. The outer side refers to the side opposite to the inner side.

The second side wall (312) may include a second inner wall (312a) arranged to face inward, and a second outer wall (312b) arranged to face outward. The second inner wall (312a) and the first inner wall (311a) may be arranged to face each other.

The above main body (3) may include a third side wall (313) and a fourth side wall (314).

The third side wall (313) and the fourth side wall (314) are arranged to be spaced apart from each other in the second axial direction (Y-axis direction) among the side walls (31). The second axial direction (Y-axis direction) and the first axial direction (X-axis direction) are axial directions that are arranged perpendicular to each other. With the second axial direction (Y-axis direction) as a reference, the receiving groove (2) can be arranged between the third side wall (313) and the fourth side wall (314). Accordingly, the third side wall (313) and the fourth side wall (314) are implemented to limit the flowable distance of oil received in the receiving groove (2) with the second axial direction (Y-axis direction) as a reference, thereby allowing oil to be stored in the receiving groove (2).

The third side wall (313) may include a third inner wall (313a) arranged to face inward, and a third outer wall (313b) arranged to face outward. The fourth side wall (314) may include a fourth inner wall (314a) arranged to face inward, and a fourth outer wall (314b) arranged to face outward. The fourth inner wall (314a) and the third inner wall (313a) may be arranged to face each other.

In FIGS. 3 and 4, the main body (3) is illustrated as including four side walls (31), but is not limited thereto, and the main body (3) may be implemented to include five or more side walls (31) so as to enable oil to be stored in the receiving groove (2).

Referring to FIGS. 2 to 5, the main body (2) may include a bottom wall (32).

The above bottom wall (32) is connected to each of the side walls (31). The bottom wall (32) may be arranged on the other side of the main body (2). Accordingly, the main body (2) may be implemented so that one side is opened by the receiving groove (2) and the other side is closed by the bottom wall (32). The bottom wall (32) is implemented so that oil can be stored in the receiving groove (2) by supporting oil below the receiving groove (2).

The above-described bottom wall (32) may include a passage groove (321). The passage groove (321) may be formed on an outer wall of the bottom wall (32). A four-wheel axle shaft (not shown) of the agricultural work vehicle (100) may be inserted into the passage groove (321). Accordingly, the oil pan (1) of the agricultural work vehicle according to the present invention may avoid interference with the four-wheel axle shaft by using the passage groove (321) and increase the amount of oil that the receiving groove (2) can store. The inner wall of the bottom wall (32) may be arranged to face the receiving groove (2).

Referring to FIGS. 2 to 5, the oil pan (1) of an agricultural work vehicle according to the present invention may include a first bridge (4) and a second bridge (5).

The first bridge (4) above reinforces the rigidity of the main body (3). The first bridge (4) is connected to the first inner wall (311a) of the first side wall (311) and the second inner wall (312a) of the second side wall (312), respectively, thereby connecting the first side wall (311) and the second side wall (312). Accordingly, the first bridge (4) can prevent the first side wall (311) and the second side wall (312) from vibrating independently of each other due to vibration, shaking, etc. generated during the operation of the agricultural work vehicle (1). Therefore, the first bridge (4) can reduce noise generated from the first side wall (311) and the second side wall (312). In addition, the first bridge (4) can reduce vibrations generated in the third side wall (313) and the fourth side wall (314) through the first side wall (311) and the second side wall (312) by connecting the first side wall (311) and the second side wall (312). Accordingly, the first bridge (4) can contribute to reducing noise generated in the main body (3) during the operation of the agricultural work vehicle (100).

The second bridge (5) above reinforces the rigidity of the main body (3). The second bridge (5) is connected to the first inner wall (311a) of the first side wall (311) and the second inner wall (312a) of the second side wall (312), respectively, thereby connecting the first side wall (311) and the second side wall (312). The second bridge (5) can be connected to the first inner wall (311a) and the second inner wall (312a) at a position spaced apart from the first bridge (4) along the second axial direction (Y-axis direction). Accordingly, the second bridge (5) and the first bridge (4) are implemented to connect the first side wall (311) and the second side wall (312) at different positions based on the second axial direction (Y-axis direction).

Therefore, the oil pan (1) of the agricultural work vehicle according to the present invention can further reduce noise generated in the main body (3) due to vibration, shaking, etc. generated during the operation of the agricultural work vehicle (1) by using the second bridge (5) and the first bridge (4). Accordingly, the oil pan (1) of the agricultural work vehicle according to the present invention can contribute to providing a more comfortable driving environment to the driver.

As can be seen from Table 1 below, compared to the embodiment having only the first bridge (4) (hereinafter referred to as the “first embodiment”), the embodiment having both the second bridge (5) and the first bridge (4) can further reduce noise generated from the main body (3). Table 1 shows the experimental results obtained through an experiment in which noise was measured at four locations spaced 1 m apart from each of the front, left, right, and top of the engine while operating the engine with the oil pan combined under no-load conditions. In this case, the noise measurements at the front, left, and right sides of the engine were performed between the cylinder block and the cylinder head of the engine at a height of 0.7 m from the ground.

The table above organizes the difference values obtained by subtracting the noise measurement results for the second embodiment from the noise measurement results for the first embodiment, and displays the difference values by measurement location. As can be seen from Table 1 above, the second embodiment can reduce noise by 1.89 at the front of the engine, 3.53 at the left side of the engine, 2.16 at the right side of the engine, and 1.72 at the top of the engine compared to the first embodiment. Therefore, it can be seen that the oil pan (1) of the agricultural work vehicle according to the present invention can further reduce noise generated in the main body (3) due to vibration, shaking, etc. generated during the operation of the agricultural work vehicle (1) by using the second bridge (5) and the first bridge (4).

The second bridge (5) and the first bridge (4) may be arranged to be spaced apart from the third side wall (313) and the fourth side wall (314) respectively, based on the second axial direction (Y-axis direction). The crank may be arranged between the third side wall (313) and the first bridge (4), between the first bridge (4) and the second bridge (5), and between the second bridge (5) and the fourth side wall (314), based on the second axial direction (Y-axis direction).

Here, the main body (3) may include a plurality of first connecting members (33) and a plurality of second connecting members (34).

The first connecting members (33) protrude from the first outer wall (311b) of the first side wall (311). The first connecting members (33) can be arranged to be spaced apart from each other along the second axis direction (Y-axis direction).

The second connecting members (34) protrude from the second outer wall (312b) of the second side wall (312). The second connecting members (34) may be arranged to be spaced apart from each other along the second axial direction (Y-axis direction). The second connecting members (34) and the first connecting members (33) may each be used to connect the main body (3) to other components of the agricultural work vehicle (100). The second connecting members (34) and the first connecting members (33) may each be arranged at the same position based on the second axial direction (Y-axis direction).

When the above body (3) includes the first connecting members (33) and the second connecting members (34), the second bridge (5) and the first bridge (4) can be arranged at a position spaced apart from the first connecting members (33) and the second connecting members (34) with respect to the second axial direction (Y-axis direction). Accordingly, the first connecting members (33), the second connecting members (34), the second bridge (5) and the first bridge (4) can be arranged at different positions to reinforce the rigidity of the first side wall (311) and the second side wall (312), respectively. Therefore, the oil pan (1) of the agricultural work vehicle according to the present invention is implemented so as to further reduce noise generated in the body (3) due to vibration, shaking, etc. generated during the operation of the agricultural work vehicle (1).

The second bridge (5), the first bridge (4), and the main body (3) may be formed integrally. Meanwhile, in FIGS. 3 and 4, only the second bridge (5) and the first bridge (4) are shown as being combined with the main body (3), but this is not limited thereto, and the main body (3) may be implemented so that three or more bridges are combined.

Referring to FIGS. 2 to 6, the oil pan (1) of the agricultural work vehicle according to the present invention may include a first rib (6).

The first rib (6) protrudes from the first outer wall (311b) of the first side wall (311). Accordingly, the first rib (6) reinforces the rigidity of the first side wall (311), thereby reducing vibration and noise generated in the first side wall (311) during the operation of the agricultural work vehicle (1). The first rib (6) and the main body (3) may be formed integrally.

The first rib (6) may be arranged at a position spaced apart from each of the third side wall (313) and the fourth side wall (314) by the same distance based on the second axial direction (Y-axis direction). That is, the first rib (6) may be arranged at a position spaced apart from each of the two ends of the first side wall (311) by the same distance based on the second axial direction (Y-axis direction). Accordingly, the first rib (6) may be arranged to reinforce the rigidity of the part of the first side wall (311) that is most vulnerable to vibration, thereby further reducing noise generated from the first side wall (311).

The first rib (6) may protrude from the first outer wall (311b) between the first bridge (4) and the second bridge (5) with respect to the second axial direction (Y-axis direction). Accordingly, the first rib (6), the first bridge (4), and the second bridge (5) may be implemented to reinforce the rigidity of the first side wall (311) at different positions with respect to the second axial direction (Y-axis direction). Accordingly, the oil pan (1) of the agricultural work vehicle according to the present invention is implemented to further reduce noise generated in the main body (3) due to vibration, shaking, etc. generated during the operation of the agricultural work vehicle (1).

The first rib (6) may protrude from the first outer wall (311b) at a position spaced apart from each of the first bridge (4) and the second bridge (5) by an equal distance based on the second axial direction (Y-axis direction). Accordingly, the first rib (6) may be arranged to reinforce the rigidity of the first side wall (311) at a position spaced apart by the furthest distance from a portion where the rigidity is reinforced by each of the first bridge (4) and the second bridge (5). Accordingly, the first rib (6) may further reduce noise generated from the first side wall (311).

The above first rib (6) may include a first protruding member (61) and a first reducing member (62).

The first protruding member (61) protrudes from the first outer wall (311b) at a position spaced apart from the bottom wall (32) along the third axis direction (Z-axis direction). The third axis direction (Z-axis direction) is an axial direction perpendicular to each of the first axis direction (X-axis direction) and the second axis direction (Y-axis direction). The second axis direction (Z-axis direction) may correspond to the height direction of the main body (3). In this case, the first protruding member (61) may be arranged at a position spaced apart from each of the upper and lower ends of the first side wall (311).

The first reducing member (62) protrudes from the first protruding member (61) toward the bottom wall (32) based on the third axis direction (Z-axis direction). That is, the first reducing member (62) may protrude downward from the first protruding member (61). In this case, the first reducing member (62) may protrude downward from the first protruding member (61) and may protrude outward from the first outer wall (311b). The first reducing member (62) may be formed so that its size decreases as it protrudes downward. Accordingly, the first rib (6) can increase the area of the portion reinforcing the rigidity of the first side wall (311) by using the first reducing member (62), while reducing the degree of weight increase due to the increase in the area of the portion reinforcing the rigidity of the first side wall (311). That is, the first rib (6) is implemented so as to increase the rigidity reinforcement of the first side wall (311) while also realizing weight reduction. The first reducing member (62) can be formed so that the length protruding outward from the first outer wall (311b) decreases as it protrudes downward. The first reducing member (62) and the first protruding member (61) may be formed integrally.

The first reducing member (62) may be formed to protrude further in the downward direction than the first bridge (4). In this case, the first bridge (4) may include a first lowest portion (41, illustrated in FIG. 6) spaced apart from the bottom wall (32) by the shortest distance based on the third axis direction (Y-axis direction). The first lowest portion (41) is a portion of the first bridge (4) coupled to the first side wall (311) that is spaced apart from the bottom wall (32) by the shortest distance. The first reducing member (62) may be formed to protrude further in the downward direction than the first lowest portion (41). Accordingly, a portion of the first side wall (311) whose rigidity is not reinforced by the first bridge (4) may be reinforced by the first reducing member (62) of the first rib (6). Therefore, the oil pan (1) of the agricultural work vehicle according to the present invention can further reduce noise generated from the first side wall (311) by using the first rib (6). The first lowest portion (41) may be arranged at a position corresponding to the first boundary portion (63) of the first protruding member (61) and the first reducing member (62) based on the third axial direction (Z-axis direction). In this case, the first boundary portion (63) and the first lowest portion (41) may be arranged at the same height (line II, illustrated in FIG. 6) based on the third axial direction (Z-axis direction).

The first rib (6) may protrude downward from one of the first connecting members (33). Although not shown, the oil pan (1) of the agricultural work vehicle according to the present invention may include a plurality of the first ribs (6). In this case, the first ribs (6) may be arranged at positions spaced apart from each other along the second axial direction (Y-axis direction).

Referring to FIGS. 2 to 6, the oil pan (1) of the agricultural work vehicle according to the present invention may include a second rib (7).

The second rib (7) protrudes from the second outer wall (312b) of the second side wall (312). Accordingly, the second rib (7) reinforces the rigidity of the second side wall (312), thereby reducing vibration and noise generated in the second side wall (312) during the operation of the agricultural work vehicle (1). The second rib (7) and the main body (3) may be formed integrally.

The second rib (7) may be arranged at a position spaced apart from each of the third side wall (313) and the fourth side wall (314) by the same distance based on the second axial direction (Y-axis direction). That is, the second rib (7) may be arranged at a position spaced apart from each of the two ends of the second side wall (312) by the same distance based on the second axial direction (Y-axis direction). Accordingly, the second rib (7) may be arranged to reinforce the rigidity of the part of the second side wall (312) that is most vulnerable to vibration, thereby further reducing noise generated from the second side wall (312).

The second rib (7) may protrude from the second outer wall (312b) between the first bridge (4) and the second bridge (5) with respect to the second axial direction (Y-axis direction). Accordingly, the second rib (7), the first bridge (4), and the second bridge (5) may be implemented to reinforce the rigidity of the second side wall (312) at different positions with respect to the second axial direction (Y-axis direction). Accordingly, the oil pan (1) of the agricultural work vehicle according to the present invention is implemented to further reduce noise generated from the main body (3) due to vibration, shaking, etc. generated during the operation of the agricultural work vehicle (1).

The second rib (7) may protrude from the second outer wall (312b) at a position spaced apart from each of the first bridge (4) and the second bridge (5) by the same distance based on the second axial direction (Y-axis direction). Accordingly, the second rib (7) may be arranged to reinforce the rigidity of the second side wall (312) at a position spaced apart the farthest from a portion where the rigidity is reinforced by each of the first bridge (4) and the second bridge (5). Accordingly, the second rib (7) may further reduce noise generated from the second side wall (312). In this case, the second rib (7) may protrude from the second outer wall (312b) at the same position as the first rib (6) based on the second axial direction (Y-axis direction).

The above second rib (7) may include a second protruding member (71) and a second reducing member (72).

The second protruding member (71) protrudes from the second outer wall (312b) at a position spaced apart from the bottom wall (32) along the third axis direction (Z-axis direction). In this case, the second protruding member (71) may be positioned at a position spaced apart from the upper and lower ends of the second side wall (312).

The second reducing member (72) protrudes from the second protruding member (71) toward the bottom wall (32) based on the third axis direction (Z-axis direction). That is, the second reducing member (72) may protrude downward from the second protruding member (71). In this case, the second reducing member (72) may protrude downward from the second protruding member (71) and outward from the second outer wall (312b). The second reducing member (72) may be formed so that its size decreases as it protrudes downward. Accordingly, the second rib (7) can increase the area of the portion reinforcing the rigidity of the second side wall (312) by using the second reducing member (72), while reducing the degree of weight increase due to the increase in the area of the portion reinforcing the rigidity of the second side wall (312). That is, the second rib (7) is implemented so as to increase the rigidity reinforcement of the second side wall (312) while also realizing weight reduction. The second reducing member (72) can be formed so that the length protruding outward from the second outer wall (312b) decreases as it protrudes downward. The second reducing member (72) and the second protruding member (71) may be formed integrally.

The second reducing member (72) may be formed to protrude further in the downward direction than the first bridge (4). In this case, the first bridge (4) may include a second lowest portion (41', illustrated in FIG. 6) spaced apart from the bottom wall (32) by the shortest distance based on the third axis direction (Y-axis direction). The second lowest portion (41') is a portion of the first bridge (4) coupled to the second side wall (312) that is spaced apart from the bottom wall (32) by the shortest distance. The second reducing member (72) may be formed to protrude further in the downward direction than the second lowest portion (41'). Accordingly, a portion of the second side wall (312) whose rigidity is not reinforced by the first bridge (4) may be reinforced by the second reducing member (72) of the second rib (7). Therefore, the oil pan (1) of the agricultural work vehicle according to the present invention can further reduce noise generated from the second side wall (312) by using the second rib (7). The second lowest portion (41') may be arranged at a position corresponding to the second boundary portion (73) of the second protruding member (71) and the second reducing member (72) with respect to the third axial direction (Z-axis direction). In this case, the second boundary portion (73) and the second lowest portion (41') may be arranged at the same height (line II) with respect to the third axial direction (Z-axis direction). The second boundary portion (73), the second lowest portion (41'), the first boundary portion (63), and the first lowest portion (41) may also be arranged at the same height (line II) with respect to the third axial direction (Z-axis direction).

The second rib (7) may protrude downward from one of the second connecting members (34). Although not shown, the oil pan (1) of the agricultural work vehicle according to the present invention may include a plurality of second ribs (7). In this case, the second ribs (7) may be arranged at positions spaced apart from each other along the second axial direction (Y-axis direction).
