[0033] The utility model embodiment provides a cylinder body, please refer to Figure 1 , Figure 2 and Figure 6 , including a cylinder body 10 and a bearing seat 11.

[0034] The bearing seat 11 is embedded in the cylinder body 10, and the bearing seat 11 is provided with a bearing hole 12 that passes through the bearing seat 11 along the first axis. The cylinder body 10 covers at least part of the bearing seat 11 in the direction of the first axis, and the bearing hole 12 is exposed. Specifically, exposed means that the bearing hole 12 is not covered or partially blocked, ensuring that the bearing hole 12 can be installed with the crankshaft. Optionally, the bearing seat 11 can be made of ductile iron to improve the rigidity, and the thermal expansion coefficient of ductile iron is smaller than that of aluminum alloy. During the operation of the engine, under the action of thermal load, the bearing seat 11 made of ductile iron can effectively reduce the gap change and improve the NVH consistency of the engine. Optionally, the upper part of the bearing seat 11 is made into a stepped section. This cross-sectional design method can reduce the weight as much as possible and increase the depth of bonding with the aluminum substrate under the premise of ensuring a certain strength of the bearing seat 11. Optionally, the bearing seat 11 is symmetrical about the BB dotted line.

[0035] By setting a cylinder body 10 and a bearing seat 11, the bearing seat 11 is embedded in the cylinder body 10, and the bearing seat 11 is provided with a bearing hole 12 that passes through the bearing seat 11 along the first axis. The cylinder body 10 covers at least a portion of the bearing seat 11 in the direction of the first axis, and the bearing hole 12 is exposed. The utility model improves the bonding strength between the bearing seat 11 and the cylinder body.

[0036] Among them, the embedding of the bearing seat 11 into the cylinder body 10 can be achieved in the following way: the bearing seat 11 is installed into the cylinder body 10, and high-temperature molten aluminum is added at the connection between the bearing seat 11 and the cylinder body 10. The molten aluminum is cooled to form an aluminum alloy, which becomes a part of the cylinder body 10, so that the bearing seat 11 is tightly connected to the cylinder body 10.

[0037] In this embodiment, embedding refers to installing the bearing seat 11 into the accommodating space reserved on the cylinder body 10, and then adding aluminum liquid to form a close fitting relationship between the bearing seat 11 and the cylinder body 10, thereby avoiding the friction of directly pressing the bearing seat 11 into the cylinder body 10 and reducing mechanical damage.

[0038] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The bearing seat 11 includes a main body 111 and a support portion. The support portion and the main body 111 are connected to each other. The bearing hole 12 is provided on the support portion. The main body 111 is provided with a first through hole 13. At least part of the cylinder body 10 is embedded in the first through hole 13.

[0039] Optionally, the inner wall surface of the first through hole 13 is connected to the cylinder body 10 , and the inner wall surface of the first through hole 13 is at least partially covered by the cylinder body 10 .

[0040] Optionally, after the bearing seat 11 is embedded in the cylinder body 10, when the next process is executed, the inner wall surface of the first through hole 13 is covered with molten aluminum. After the molten aluminum is cooled, an aluminum alloy edging is formed on the inner wall surface of the first through hole 13. The aluminum alloy edging becomes a part of the cylinder body 10, thereby ensuring the bonding strength between the bearing seat 11 and the aluminum substrate.

[0041] Optionally, the first through hole 13 may be a polygonal hole, a circular hole, an elliptical hole, an irregular hole, etc. Optionally, the first through hole 13 may be, but is not limited to, a quadrilateral hole, a pentagonal hole, a hexagonal hole, an octagonal hole, a circular hole, an elliptical hole, an irregular hole, etc.

[0042] Specifically, the first through hole 13 is connected and matched with the cylinder body, thereby increasing the bonding strength between the cylinder body 10 and the bearing seat 11 .

[0043] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The number of the first through holes 13 is multiple, and the multiple first through holes 13 are arranged at intervals.

[0044] Optionally, after the bearing seat 11 is embedded in the cylinder body 10, when the next process is executed, the inner wall surfaces of the multiple first through holes 13 are covered with molten aluminum. After the molten aluminum is cooled, an aluminum alloy edging is formed on the inner wall surfaces of the multiple first through holes 13, thereby ensuring the bonding strength between the bearing seat 11 and the aluminum substrate.

[0045] Optionally, the number of the first through holes 13 ranges from 2 to 6. Optionally, the number of the first through holes 13 ranges from 2, 3, 5 and 6. Optionally, the plurality of first through holes 13 are arranged at equal intervals.

The ratio of E1 to the diameter of the bearing hole 12 is in the range of 0.1 to 0.2. Optionally, the shortest distance between the inner walls of the two first through holes 13 is E2. The size of E2 directly affects the load-bearing width of the ductile iron material above the bearing hole 12. If E2 is too small, the strength above the bearing hole 12 will be affected. If E2 is too large, the wall thickness between the inner wall of the first through hole 13 and the inner wall of the second through hole 15 will be reduced, affecting the strength.

[0047] Optional, please refer to Figure 1 and Figure 2 The first through hole 13 is a rectangular hole, the length of the first through hole 13 is L1, and the width of the first through hole 13 is L2, which satisfies: 1.0≤L1 / L2≤1.1.

[0053] Optionally, the distance from the bottom surface of the sink 14 to the mounting surface of the second through hole 15 is N1, and the range of N1 is 6 mm to 10 mm, ensuring that the aluminum alloy of sufficient thickness contacts the bearing seat 11 and improving the overall strength.
