[0031] Reference below Figure 1-Figure 4 A cylinder block 100 according to an embodiment of the utility model is described, in which the main oil passage 1 of the cylinder block 100 is connected with the oblique oil hole 2 through a connecting space 13, and the tapered port 11 of the main oil passage 1 is used to seal the main oil passage 1 and the oblique oil hole 2, so that the oblique oil hole 2 is blocked when the tapered screw plug 12 seals the main oil passage 1 and the oblique oil hole 2, thereby preventing the oblique oil hole 2 from being blocked and causing lubrication failure of the oblique oil hole 2.

[0032] Among them, the main oil channel 1 and the oblique oil hole 2 in this embodiment are both oil circuit divisions of the lubrication system in the cylinder block 100. The lubrication system is one of the important subsystems of the gasoline engine, providing power lubrication for each friction pair of the gasoline engine, and its lubrication performance directly affects the performance and life of the engine. In addition, the space structure in the cylinder block 100 is limited, and the connectivity and sealing performance of multiple oil circuits are very important, which directly affects whether the lubrication of the corresponding parts is effective.

[0033] like Figure 1-Figure 4 As shown, according to an embodiment of the present invention, a cylinder block 100 is provided with a main oil passage 1 and an oblique oil hole 2 connected to a bearing mounting hole 3 in the cylinder block 100 , and a cylinder head connecting hole 4 is provided on one side of the oblique oil hole 2 close to the main oil passage 1 in the cylinder block 100 .

[0034] Specifically, a main oil channel 1 and an oblique oil hole 2 are provided in the cylinder block 100. The main oil channel 1 is used to transport the sucked engine oil to other oil circuits that need lubrication, wherein the oblique oil hole 2 is connected to the bearing mounting hole 3, and a bearing is installed at the bearing mounting hole 3. The oblique oil hole 2 is used to lubricate the shaft system structure such as the bearing, and the cylinder block 100 is also provided with a cylinder head connecting hole 4. The cylinder block 100 can be connected to the cylinder head by a connecting piece penetrated through the cylinder head connecting hole 4. The cylinder head connecting hole 4 is located on the side of the oblique oil hole 2 close to the main oil channel 1, and the cylinder head connecting hole 4 and the oblique oil hole 2 are spaced apart and distributed along the extension direction of the main oil channel 1, and the spacing between the two cannot be too small. It is necessary to ensure the structural strength of the cylinder head connecting hole 4 to improve the connection strength between the cylinder head and the cylinder block 100.

[0035] An open conical port 11 is formed at one end of the main oil passage 1 , and the conical port 11 is used to insert a conical plug 12 , that is, by inserting the conical plug 12 into the conical port 11 , the end of the main oil passage 1 can be closed and sealed.

[0036] Specifically, a conical port 11 is formed at the end of the main oil passage 1, and a conical screw plug 12 is inserted from the open port into the conical port 11 to seal the main oil passage 1, thereby achieving oil circuit sealing. The conical screw plug 12 is arranged to cooperate with the conical port 11, so that the sealing effect is better and the engine oil is less likely to leak.

[0037] Among them, the cylinder body 100 is also formed with a connecting space 13 at the tapered port 11, and the inclined oil hole 2 is connected with the main oil channel 1 through the tapered port 11 and the connecting space 13 to realize the connection between the inclined oil hole 2 and the main oil channel 1, that is, the inclined oil hole 2 is connected to one end of the main oil channel 1, and can be connected with the tapered port 11 through the connecting space 13.

[0038] Specifically, the cylinder block 100 is provided with a connecting space 13 at the tapered port 11. The connecting space 13 can be constructed as a circular groove concentric with the tapered port 11, or can be constructed as a partial arc groove. The connecting space 13 is located between the tapered port 11 and the main oil channel 1, and the inclined oil hole 2 is connected with the connecting space 13 and the tapered port 11, so that the inclined oil hole 2 is connected with the main oil channel 1. In this way, the engine oil in the main oil channel 1 flows to the inclined oil hole 2, which can meet the lubrication demand of the inclined oil hole 2. It has a simple structure and low processing cost.

[0039] Among them, it should be noted that when the connecting space 13 is not set, the end of the main oil channel 1 is connected and sealed with the tapered port 11 through the tapered plug 12, which will block part of the inclined oil hole 2, so that the main oil channel 1 cannot deliver enough engine oil to the inclined oil hole 2, resulting in insufficient lubrication of the bearing at the inclined oil hole 2. The connecting space 13 set in this embodiment, when the tapered plug 12 seals the tapered port 11 of the main oil channel 1, the inclined oil hole 2 can still be connected with the main oil channel 1 through the connecting space 13, preventing the inclined oil hole 2 from being unable to replenish the engine oil, ensuring the lubrication demand at the bearing mounting hole 3, thus, setting the connecting space 13 between the original main oil channel 1 and the inclined oil hole 2, can ensure that there is enough engine oil in the inclined oil hole 2, ensure the lubrication demand of the moving structural parts, and the dynamic lubrication of each friction pair of the engine is better, thereby improving the performance and service life of the engine.

[0040] That is to say, by setting the connecting space 13, the sealing requirement of the end of the main oil channel 1 can be met, and the effective oil supply of the inclined oil hole 2 can be guaranteed. At the same time, there is no need to adjust the position of the inclined oil hole 2, which solves the problem that the cylinder head connecting hole 4 restricts the position of the inclined oil hole 2, making the position of the inclined oil hole 2 unadjustable and resulting in abnormal oil supply. It ensures that the cylinder head connecting hole 4 and the inclined oil hole 2 have a reasonable distance in the cylinder body 100, avoids the distance between the cylinder head connecting hole 4 and the inclined oil hole 2 being too small, and ensures the structural strength of the cylinder body 100.

[0041] According to the cylinder block 100 of the embodiment of the utility model, a connecting space 13 is provided at the tapered port 11 of the main oil channel 1, so that the inclined oil hole 2 is connected with the main oil channel 1 through the connecting space 13, which can meet the sealing requirement of the main oil channel 1 using the tapered screw plug 12, and can meet the lubrication requirement of the inclined oil hole 2, so as to improve the lubrication performance of the lubrication system, and the structure is simple and reliable.

[0042] In some embodiments, the communication space 13 is located on the side of the inclined oil hole 2 close to the main oil channel 1. Specifically, Figure 1-Figure 4 As shown, the connecting space 13 is arranged at the connection between the inclined oil hole 2 and the main oil gallery 1, and the connecting space 13 is on the side of the inclined oil hole 2 close to the main oil gallery 1, and the connecting space 13 is used to circulate the engine oil from the main oil gallery 1 to the inclined oil hole 2. In addition, the tapered port 11 is arranged at the connection between the inclined oil hole 2 and the main oil gallery 1, and the tapered port 11 is on the side of the inclined oil hole 2 away from the main oil gallery 1, that is, the connecting space 13 and the tapered port 11 are separated by the inclined oil hole 2. In this way, when the tapered plug 12 is connected to the tapered port 11, the inclined oil hole 2 will not be blocked, and the inclined oil hole 2 is connected to the main oil gallery 1 through the connecting space 13, then the engine oil of the main oil gallery 1 enters the inclined oil hole 2 through the connecting space 13 to lubricate the bearing mounting hole 3 in the inclined oil hole 2.

[0043] Therefore, a connecting space 13 is set at the connection between the original main oil channel 1 and the inclined oil hole 2, which can make up for the deficiency that the inclined oil hole 2 cannot be moved along the extension direction of the main oil channel 1. At the same time, the tapered screw plug 12 can be avoided, and only one connecting space 13 is set, which can reduce the setting of redundant oil pipes at the connection between the main oil channel 1 and the inclined oil hole 2 and reduce costs.

[0044] In some embodiments, the communication space 13 is eccentrically arranged relative to the axis of the main oil gallery 1 in the cylinder block 100, that is, the communication space 13 and the main oil gallery 1 are not arranged concentrically. Figure 1 and Figure 4 As shown, in the cylinder block 100, the connecting space 13 is eccentrically arranged relative to the axis of the main oil gallery 1, and is eccentric toward the side close to the inclined oil hole 2. The connecting space 13 extends along the axial direction of the main oil gallery 1, and the extension length is relatively small. The connecting space 13 is arranged to overlap with the space of the main oil gallery 1, which can satisfy the main oil gallery 1 to provide sufficient engine oil to the inclined oil hole 2 to ensure the lubrication requirement of the inclined oil hole 2.

[0045] Therefore, by eccentrically setting the connecting space 13, the position of the main oil channel 1 close to the inclined oil hole 2 can be utilized to avoid affecting the structural strength of the tapered port 11, thereby ensuring the sealing effect of the tapered plug 12 on the main oil channel 1, and the structural setting is reasonable and effective.

[0046] Among them, the connecting space 13 can also be set concentrically with the main oil channel 1, that is, the connecting space 13 can be constructed as an arc groove or a circular arc groove, which is simpler and more convenient to process, and can be selected and set according to actual space requirements, as long as it can meet the installation strength of the tapered screw plug 12.

[0047] In some embodiments, when the tapered plug 12 is inserted into the tapered port 11 , the cut-off area of ​​the communication space 13 between the main oil passage 1 and the oblique oil hole 2 is larger than the cut-off area of ​​the oblique oil hole 2 .

[0048] Specifically, Figure 1 As shown, the connecting space 13 between the main oil channel 1 and the inclined oil hole 2 has a large cut-off area, and is larger than the cut-off area of ​​the inclined oil hole 2 itself. In this way, when the tapered plug 12 is inserted into the tapered port 11, the main oil channel 1 is connected with the inclined oil hole 2 through the connecting space 13, and the oil in the main oil channel 1 can enter the inclined oil hole 2 from the connecting space 13, so that more oil can be provided to the inclined oil hole 2 to meet the lubrication demand of the inclined oil hole 2.

[0049] Among them, when the tapered plug 12 is inserted into the tapered port 11, more space at the connection between the main oil channel 1 and the inclined oil hole 2 is blocked by the tapered plug 12, and the setting of the connecting space 13 just makes up for the blocking of the inclined oil hole 2, and the intercepting area of ​​the connecting space 13 is set to be larger than the intercepting area of ​​the inclined oil hole 2, so that when the engine is working, a large amount of oil in the main oil channel 1 can flow normally into the inclined oil hole 2, and the bearings and other structural parts at the inclined oil hole 2 are dynamically lubricated, which can effectively reduce the friction of the structural parts here. In addition, the structure of the connecting space 13 is reasonably set, and the overall lubrication performance is higher.

[0050] In some embodiments, the communication space 13 is configured to have a circular cross section, and the axis of the communication space 13 is parallel and spaced apart from the axis of the main oil gallery 1 .

[0051] Specifically, Figure 3 and Figure 4 As shown, in the present embodiment, the connecting space 13 can be constructed as a circular slot having a circular cross-section, the axis of the connecting space 13 is parallel to the axis of the main oil channel 1 and is spaced apart from it, and is spaced apart from the main oil channel 1 on the side close to the inclined oil hole 2. In this way, the connecting space 13 and the main oil channel 1 are both set to circular structures, so that the connection between the main oil channel 1 and the inclined oil hole 2 at the connecting space 13 is smoother, which can reduce the resistance encountered when the engine oil flows from the main oil channel 1 to the inclined oil hole 2, and can improve the lubrication efficiency at the inclined oil hole 2.

[0052] Therefore, the two axes are arranged in parallel and spaced apart, the structure is simple and the processing is convenient, and the spacing of the axes can make the inner wall of the connecting space 13 deviate toward the inclined oil hole 2, thereby increasing the space size at the connection between the main oil channel 1 and the inclined oil hole 2, so that when the tapered plug 12 is inserted into the tapered port 11, the connecting intercepting area between the main oil channel 1 and the inclined oil hole 2 is large, thereby meeting the oil supply of the main oil channel 1 to the inclined oil hole 2.

[0053] Among them, the connecting space 13 can also be constructed as a square slot, etc., so that when the tapered plug 12 is inserted into the tapered port 11, there is enough oil flow area at the connection between the main oil channel 1 and the inclined oil hole 2 to meet the lubrication requirements of the inclined oil hole 2.

[0054] In some embodiments, the cut-off area of ​​the main oil passage 1 is larger than the cut-off area of ​​the inclined oil hole 2 , and the cut-off area of ​​the connecting space 13 is larger than the cut-off area of ​​the main oil passage 1 .

[0055] Specifically, the main oil channel 1 is the main lubrication oil channel of the lubrication system, and the inclined oil hole 2 is a lubrication branch oil channel specifically for lubricating shaft structures. The cut-off area of ​​the main oil channel 1 is set to the maximum and is larger than the cut-off area of ​​the inclined oil hole 2. A sealing structure is provided at the connection between the main oil channel 1 and the inclined oil hole 2. In this way, the cut-off area of ​​the connecting space 13 can be larger than the cut-off area of ​​the main channel, which can facilitate the main oil channel 1 to provide sufficient engine oil to the inclined oil hole 2 through the connecting space 13. When the lubrication system starts working, the high-pressure lubricating oil enters the main oil channel 1, and the high-pressure lubricating oil in the main oil channel 1 enters the inclined oil hole 2 through the connecting space 13 with a larger cut-off area to lubricate the bearing mounting hole 3 in the inclined oil hole 2. The main oil channel 1 is also connected to other branch oil channels, which can simultaneously meet the lubrication needs of multiple oil channels and has better lubrication performance.

[0056] In some embodiments, the extension direction of the main oil passage 1 is perpendicular to the extension direction of the oblique oil hole 2 , and at least a portion of the communication space 13 is located inside the corner where the main oil passage 1 is connected to the oblique oil hole 2 .

[0057] Specifically, Figure 1 As shown, the inclined oil hole 2 is a branch oil passage of the main oil passage 1, and the extension direction of the main oil passage 1 is perpendicular to the extension direction of the inclined oil hole 2. The main oil passage 1 and the inclined oil hole 2 are both located in the cylinder block 100, that is, the extension direction of the main oil passage 1 can be the front-to-back direction, and the extension direction of the inclined oil hole 2 can be the left-to-right direction. The connecting space 13 is arranged on the inner side of the corner between the main oil passage 1 and the inclined oil hole 2, and at least part of the connecting space 13 coincides with the main oil passage 1 and the inclined oil hole 2, and the tapered port 11 is arranged on the outer side of the corner between the main oil passage 1 and the inclined oil hole 2. In this way, after the tapered port 11 is sealed by the tapered plug 12 at the port of the main oil passage 1, the engine oil of the main oil passage 1 flows into the inclined oil hole 2 through the inner connecting space 13, so as to meet the lubrication demand at the inclined oil hole 2, and the connecting space 13 is reasonably and reliably distributed.

[0058] In some embodiments, the bearing mounting hole 3 and the cylinder head connecting hole 4 are respectively located on both sides of the oblique oil hole 2. Figure 1As shown, the bearing mounting hole 3 is connected with the oblique oil hole 2, and the bearing mounting hole 3 is located on the side of the oblique oil hole 2 away from the main oil channel 1, the cylinder head connecting hole 4 is separated from the oblique oil hole 2, and is located on the side of the oblique oil hole 2 close to the main oil channel 1, and the bearing mounting hole 3 is separated from the oblique oil hole 2 and distributed on both sides of the oblique oil hole 2, and the two are separated and distributed on the same side of the main oil channel 1, and the bearing mounting hole 3, the cylinder head connecting hole 4, the oblique oil hole 2 and the main oil channel are all arranged on the cylinder block 100, and are separated and distributed from each other, which can ensure the structural strength of the cylinder block 100, and when the oblique oil hole 2 lubricates the shafting structural parts such as the bearing in the bearing mounting hole 3, the structural strength of the cylinder head connecting hole 4 can be ensured.

[0059] The utility model also provides an engine.

[0060] According to the engine of the embodiment of the utility model, it includes a cylinder head and a cylinder block 100 of any one of the above embodiments, and the cylinder head and the cylinder block 100 are detachably connected through a connecting member penetrating through the cylinder head connecting hole 4, wherein the connecting member can be a connecting bolt, and the connecting bolt is passed through the cylinder head connecting hole 4 and is threadedly connected to the cylinder head and the cylinder block 100 respectively, and its connection method is simple and easy to disassemble and assemble, and the structural strength requirement at the cylinder head connecting hole 4 is relatively high. It should be noted that the oil circuit arrangement in this embodiment is restricted by the cylinder head connecting hole 4, and the inclined oil hole 2 cannot move in the axial direction of the main oil channel 1. The main oil channel 1 is the high-pressure oil circuit of the cylinder block 100, which is used to ensure the lubrication requirements of all moving parts. The inclined oil hole 2 is required for bearing lubrication, and the splash lubrication of the bearing mounting hole 3 is insufficient, and high-pressure oil circuit lubrication is added thereto. Through the connecting space 13 added in this embodiment, the problem of insufficient lubrication of the inclined oil hole 2 can be effectively solved, thereby improving the lubrication performance of the structural parts at the inclined oil hole 2 in the engine, so as to improve the performance and life of the engine.

[0061] The utility model also provides a vehicle.

[0062] The vehicle according to the embodiment of the utility model includes the engine of the above embodiment. The working performance of the engine directly affects the performance of the vehicle. Among them, the lubrication system is one of the important systems in the engine. In this embodiment, a connecting space 13 is provided at the tapered port 11 of the main oil channel 1, so that the inclined oil hole 2 is connected with the main oil channel 1 through the connecting space 13, which can meet the sealing requirements of the main oil channel 1 using the tapered screw plug 12 and the lubrication requirements of the inclined oil hole 2, so as to improve the lubrication performance of the lubrication system, and the structure is simple and reliable.
