[0023] Embodiments of the present utility model will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Below, reference is made to Figure 1 - Figure 2 Describe an auxiliary tooling 100 for flywheel housing lubrication according to an embodiment of the present utility model. The auxiliary tooling 100 for flywheel housing lubrication includes: a body portion 10 and a plurality of connecting portions 20.

[0024] Specifically, as Figure 1 shown, the plurality of connecting portions 20 are provided on the outer peripheral side of the body portion 10, and the plurality of connecting portions 20 are adapted to cooperate with the mounting holes of the flywheel housing.

[0025] The auxiliary tooling 100 designed in this application is used to cooperate with the accommodating cavity of the flywheel housing, facilitating the application of grease at the opening of the accommodating cavity. The flywheel housing is formed with a plurality of mounting holes, and the plurality of mounting holes are arranged at intervals along the circumferential direction of the flywheel housing. When the auxiliary tooling 100 is assembled with the flywheel housing, the body portion 10 is adapted to fit with the flywheel housing. The plurality of connecting portions 20 provided on the outer peripheral side of the body portion 10 are opposite to the plurality of mounting holes. The plurality of connecting portions 20 are arranged at intervals along the outer peripheral edge of the body portion 10, and the plurality of connecting portions 20 can respectively cover the plurality of mounting holes.

[0026] For the auxiliary tooling 100 for flywheel housing lubrication according to an embodiment of the present utility model, when the flywheel housing needs to be lubricated, the body portion 10 of the auxiliary tooling 100 for flywheel housing lubrication is aligned with the flywheel housing along the thickness direction of the body portion 10, so that the plurality of connecting portions 20 cover the mounting holes on the flywheel housing. Thus, when applying grease to the surface provided with the mounting holes, it can prevent the grease from entering the mounting holes on the flywheel housing and into the flywheel housing, avoiding the situation that the fasteners are loose or cannot be tightened in the mounting holes during the assembly process of the flywheel housing with other structural parts, and improving the reliability. At the same time, the efficiency of applying grease can be improved, and the auxiliary tooling 100 for applying grease has a simple structure, which can effectively reduce costs.

[0027] According to some embodiments of the present utility model, the flywheel housing has a mounting surface, and a plurality of mounting holes are formed on the mounting surface; the plurality of connecting portions 20 are respectively opposite to the plurality of mounting holes along the thickness direction of the connecting portions 20.

[0028] The flywheel housing forms a mounting surface at one end adjacent to the body portion 10 along the thickness direction of the body portion 10. The mounting surface is used to mount other components of the flywheel housing. The plurality of mounting holes are arranged at intervals along the outer peripheral edge of the mounting surface. That is, when the flywheel housing needs to be lubricated, the plurality of connecting portions 20 of the auxiliary tooling 100 for flywheel housing lubrication are respectively aligned with the plurality of mounting holes of the flywheel housing along the thickness direction of the body portion 10, forming a cover for the mounting holes.

[0029] Thus, multiple connecting portions 20 are respectively opposite to multiple mounting holes along the thickness direction of the connecting portion 20, improving the positioning accuracy and installation efficiency of the auxiliary tool 100 for flywheel housing lubrication and the flywheel housing. At the same time, when the flywheel housing is lubricated, the outer peripheral edge of the body portion 10 can provide a guiding lubrication effect for the brush. The multiple connecting portions 20 cover the multiple mounting holes respectively, preventing the lubricating grease from entering the multiple mounting holes, so that the lubricating grease can be evenly applied to other areas of the mounting surface except the mounting holes, which is beneficial to keeping the mounting surface lubricated and having an anti-rust effect.

[0030] According to some embodiments of the present invention, as Figure 1 shown, at least one of the multiple connecting portions 20 is formed with a connecting hole 21, and the connecting hole 21 is connected to any one of the multiple mounting holes.

[0031] That is, a connecting hole 21 is formed on one of the multiple connecting portions 20 provided. The connecting hole 21 is opposite to one of the multiple mounting holes along the thickness direction of the body portion 10. The limiting member 22 passes through the connecting hole 21 and the mounting hole opposite to the connecting hole 21 to fix the auxiliary tool 100 on the flywheel housing, realizing the assembly of the auxiliary tool 100 and the flywheel housing, and facilitating the application of the lubricating grease on the mounting surface.

[0032] In this embodiment, two of the multiple connecting portions 20 are respectively formed with connecting holes 21, and the two connecting holes 21 are arranged opposite to each other along the radial direction of the body portion 10. That is, the two connecting holes 21 are respectively arranged on both sides of the flywheel housing along the radial direction and are respectively matched with the corresponding mounting holes, which is convenient for increasing the convenience and reliability of the installation of the flywheel housing and the auxiliary tool 100, and avoiding the deviation of the auxiliary tool 100 from affecting the painting accuracy.

[0033] Thus, at least one of the multiple connecting portions 20 is formed with a connecting hole 21, and the connecting hole 21 is connected to any one of the multiple mounting holes, which can facilitate the assembly of the auxiliary tool 100 for flywheel housing lubrication and the flywheel housing, improve the positioning accuracy and assembly efficiency between the auxiliary tool 100 for flywheel housing lubrication and the flywheel housing, and improve the connection strength between the auxiliary tool 100 for flywheel housing lubrication and the flywheel housing.

[0034] According to some embodiments of the present invention, the width of the connecting portion 20 along the circumferential direction of the body portion 10 is L, and L satisfies: 8 mm ≤ L ≤ 12 mm.

[0035] The width of the limiting connecting portion 20 along the circumferential direction is selected according to the diameter of the mounting hole. In this embodiment, the diameter of the mounting hole is 8 mm. To enable the connecting portion 20 to better cover the mounting hole, the size of the connecting portion 20 is made larger than that of the mounting hole, facilitating the covering of the mounting hole. For example, when the width of the connecting portion 20 along the circumferential direction of the main body portion 10 is less than 8 mm, the width of the connecting portion 20 along the circumferential direction of the main body portion 10 is too small, which may cause the connecting portion 20 to not completely cover the mounting hole, allowing the grease to enter the mounting hole, resulting in the fastener being loose or unable to be tightened in the mounting hole; when the width of the connecting portion 20 along the circumferential direction of the main body portion 10 is greater than 12 mm, the width of the connecting portion 20 along the circumferential direction of the main body portion 10 is too large, which may lead to too high a cost of the auxiliary tooling 100 for flywheel housing lubrication. At the same time, it causes waste of grease, leads to the occupation of the area around the mounting hole by the connecting portion 20, resulting in the inability to apply grease during the greasing process, reducing the greasing area and having an unsatisfactory rust prevention effect. For example, L = 10 mm.

[0036] Thus, by setting the width of the connecting portion 20 along the circumferential direction of the main body portion 10, the connecting portion 20 can completely cover the mounting hole, preventing the grease from entering the mounting hole, effectively improving the sealing performance of the mounting hole. At the same time, the amount of grease used can be controlled, the cost of the grease can be reduced, and the production cost of the auxiliary tooling 100 for flywheel housing lubrication can be saved, improving the economy.

[0037] According to some embodiments of the present invention, the main body portion 10 includes: a first main body portion 11 and a second main body portion 10. A plurality of connecting portions 20 are provided on the outer peripheral side of the first main body portion 11; the second main body portion 10 is provided on one side in the thickness direction of the first main body portion 11. One end of the second main body portion 10 is connected to the first main body portion 11, and the other end of the second main body portion 10 extends along the thickness direction of the first main body portion 11.

[0038] That is, one end of the second main body portion 10 is vertically connected to the side of the first main body portion 11 adjacent to the flywheel housing, and the other end of the second main body portion 10 extends along the thickness direction of the main body portion 10 towards the flywheel housing and fits into the receiving cavity of the flywheel housing. The connecting portion 20 is provided on the outer peripheral side of the first main body portion 11 and is connected to the first main body portion 11. The other end of the connecting portion 20 is fitted with the mounting hole. The second main body portion 10 is provided on the side of the first main body portion 11 adjacent to the flywheel housing and is vertically arranged with respect to the first main body portion 11, that is, the extending direction of the second main body portion 10 along the thickness direction of the main body portion 10 is parallel to the center line direction of the first main body portion 11. The second main body portion 10 extends along the circumferential direction of the first main body portion 11 and cooperates with the flywheel housing.

[0039] Thus, the second main body portion 10 is provided on one side in the thickness direction of the first main body portion 11. One end of the second main body portion 10 is connected to the first main body portion 11, and the other end of the second main body portion 10 extends along the thickness direction of the first main body portion 11, which can provide a guiding function for the assembly of the first main body portion 11 and the flywheel housing, and improve the structural strength and installation efficiency of the auxiliary tooling 100 for flywheel housing lubrication.

[0040] According to some embodiments of the present invention, the second main body portion 10 extends along the circumferential direction of the first main body portion 11; the flywheel housing is formed with a receiving cavity, and the second main body portion 10 cooperates with the receiving cavity.

[0041] That is, a receiving cavity is formed on the side of the flywheel housing facing the auxiliary tooling 100, and the shape of the second main body portion 10 is adapted to the receiving cavity formed on the flywheel housing. After the connection holes 21 on the first main body portion 11 are engaged with the mounting holes on the flywheel housing, the second main body portion 10 cooperates with the receiving cavity on the flywheel housing. Thus, the second main body portion 10 extends along the circumferential direction of the first main body portion 11, the flywheel housing is formed with a receiving cavity, and the second main body portion 10 cooperates with the receiving cavity. When lubricating the flywheel housing, while ensuring the lubrication of the mounting surface of the flywheel housing, it is possible to prevent the lubricating grease from entering the receiving cavity of the flywheel housing, avoid the components inside the flywheel housing from being contaminated with oil, and effectively improve safety.

[0042] According to some embodiments of the present invention, as Figure 1 and Figure 2 shown, the first main body portion 11 is provided with at least one armrest 12. The armrest 12 is provided on the side of the first main body portion 11 away from the second main body portion 10, and the armrest 12 is connected to the first main body portion 11.

[0043] That is, at least two through holes 111 are formed on the side of the first main body portion 11 away from the flywheel housing. The two through holes 111 are spaced apart along the height direction of the main body portion 10, and the armrest 12 is respectively connected to the first main body portion 11 through the two through holes 111. Thus, the armrest 12 is provided on the side of the first main body portion 11 away from the second main body portion 10, and the armrest 12 is connected to the first main body portion 11, which can facilitate the staff to grab the armrest 12, facilitate the movement of the auxiliary tooling 100 for flywheel housing lubrication, complete the assembly process of the auxiliary tooling 100 for flywheel housing lubrication and the flywheel housing, simplify the assembly process, and improve work efficiency.

[0044] According to some embodiments of the present invention, as Figure 1 shown, there are a plurality of armrests 12, and the plurality of armrests 12 are centrally symmetrically arranged along the center of the first main body portion 11.

[0045] In this embodiment, there are two armrests 12. The two armrests 12 are arranged along the radial direction of the main body part 10. While the two armrests 12 are symmetrically arranged about the center of the first main body part 11, they are respectively adjacent to the two connecting holes 21. Thus, multiple armrests 12 are symmetrically arranged about the center of the first main body part 11, making the force on the first main body part 11 uniform, facilitating the staff to grasp, and improving the assembly efficiency of the auxiliary tooling 100 for flywheel housing lubrication and the flywheel housing.

[0046] According to some embodiments of the present invention, the first main body part 11 is formed with a weight-reducing hole.

[0047] That is to say, a weight-reducing hole is formed in the first main body part 11, and the weight-reducing hole penetrates through the main body part 10 along the thickness direction of the main body part 10. Thus, the first main body part 11 is formed with a weight-reducing hole, which can reduce the weight of the main body part 10, thereby realizing the lightweight design of the auxiliary tooling 100 for flywheel housing lubrication and reducing the production cost of the auxiliary tooling 100 for flywheel housing lubrication.

[0048] According to some embodiments of the present invention, the thickness of the first main body part 11 is H, and H satisfies: 0 < H ≤ 5 mm.

[0049] When the thickness of the first main body part 11 is greater than 5 mm, the thickness of the first main body part 11 is too large, which may cause the accumulation of lubricating grease between the multiple connecting parts 20, unable to control the amount of lubricating grease, resulting in waste of lubricating grease. For example, H = 2.5 mm.

[0050] Thus, by limiting the range of the thickness of the first main body part 11, the accumulation of lubricating grease at the multiple connecting parts 20 can be avoided. While reducing the hidden danger of rust at the corners of the flywheel housing, the amount of lubricating grease can be effectively controlled, the lubricating grease cost can be saved, and the economy can be improved.

[0051] Optionally, the material of the auxiliary tooling 100 is acrylic board, which further reduces the weight of the auxiliary tooling 100 and contributes to the lightweight design of the auxiliary tooling 100.
