Abstract
The utility model relates to a cylinder liner of a gasoline engine. The cylinder liner comprises a cylinder liner body, wherein the peripheral wall of the cylinder liner body is provided with annular protrusions extending along the circumferential direction of the peripheral wall of the cylinder liner body at interval. According to the cylinder liner of the gasoline engine, disclosed by the utility model, by the arrangement of the annular protrusions on the peripheral wall of the cylinder liner body, because a groove is formed between every two adjacent annular protrusions, the side face and the bottom face of each groove are in smooth transition, the flow resistance of molten aluminum is low, the molten aluminum can easily flow into the grooves to forwards discharge air in the grooves, so that aluminum alloy and the cylinder are tightly combined, the tight packaging force is guaranteed favorably, and a die-casting effect between the cylinder liner and the aluminum alloy is better; even under the condition of canceling a cylinder liner preheating procedure, the combination between the cylinder liner and the aluminum alloy can be made tighter without air holes formed easily; and the cylinder liner higher strength and better quality, and furthermore, energy can be saved.
Description
Technical field
The utility model relates to a kind of cylinder sleeve, and concrete is a kind of petrol engine cylinder sleeve that is used for petrol engine.
Background technique
Cylinder sleeve generally adopts the centrifugal casting of phosphorus alum cast iron, and die casting at high temperature packs tightly cylinder sleeve in foundry goods with aluminum alloy then, and cylinder sleeve and aluminum alloy are combined closely, to improve the intensity of cylinder sleeve.Existing liner backs is granular, because aluminum alloy water is thicker, combines with aluminum alloy closely in order to guarantee cylinder sleeve; When die casting is produced, earlier cylinder sleeve is preheating to 280 ℃ with high-frequency apparatus, then; Reinstall die casting, equipment investment and energy consumption are all higher, and combine defective tightness between cylinder sleeve and the aluminum alloy; Be easy to generate the crack and form pore, influence the performance of cylinder sleeve.
Given this, the utility model is intended to existing petrol engine cylinder sleeve structure is improved, the petrol engine cylinder sleeve after the improvement not only can and aluminum alloy between combine closely, improve intensity, and not be used in before the die casting the cylinder sleeve preheating, save the energy and reduce cost of investment.
Summary of the invention
The technical problem that the utility model will solve is to propose a kind of petrol engine cylinder sleeve; This petrol engine cylinder sleeve not only can and aluminum alloy between combine closely more, improve intensity, and not be used in before the die casting the cylinder sleeve preheating; Cancellation cylinder sleeve preheating procedure is saved the energy and is reduced cost of investment.
Realize above-mentioned technical purpose, the petrol engine cylinder sleeve of the utility model comprises the cylinder sleeve body, and the compartment of terrain is provided with the annular protrusion that extends along said cylinder sleeve body periphery wall circumferential direction on the periphery wall of said cylinder sleeve body.
Further, the bearing of trend of said annular protrusion is vertical with the bus of said cylinder sleeve body periphery wall;
Further, the said annular protrusion said cylinder sleeve body periphery wall circumferential direction extension in shape edge in the shape of a spiral;
Further, the wide 3 ~ 4mm of said annular protrusion, dark 1 ~ 1.5mm.
The beneficial effect of the utility model is:
The petrol engine cylinder sleeve of the utility model is through being provided with annular protrusion on the periphery wall of cylinder sleeve body, owing to have groove between the adjacent annular convexity, the side and the bottom surface of groove seamlessly transit; Aluminium water flows resistance is little, is easy to flow in the groove, and gas in the groove is discharged forward; Aluminum alloy and cylinder sleeve combine closely, and package power is also well guaranteed, the die casting better effects if between cylinder sleeve and the aluminum alloy; Even under the situation of cancellation cylinder sleeve preheating procedure, also can make to combine closelyr between cylinder sleeve and the aluminum alloy, be not easy to form pore; The intensity of cylinder sleeve is higher, and better quality can also be saved the energy.
Description of drawings
Fig. 1 is the utility model petrol engine cylinder sleeve example structure schematic representation.
Embodiment
Elaborate below in conjunction with the embodiment of accompanying drawing to the utility model.
As shown in Figure 1, be the petrol engine cylinder sleeve example structure schematic representation of the utility model.The petrol engine cylinder sleeve of present embodiment comprises cylinder sleeve body 1, and the compartment of terrain is provided with the annular protrusion 2 that extends along said cylinder sleeve body 1 periphery wall circumferential direction on the periphery wall of said cylinder sleeve body 1.
Further, said annular protrusion 2 can adopt multiple structure: the bearing of trend of said annular protrusion 2 is vertical with the bus of said cylinder sleeve body 1 periphery wall; The structure of annular protrusion 2 can also for: annular protrusion 2 in the shape of a spiral shape extend along said cylinder sleeve body 1 periphery wall circumferential direction.The annular protrusion 2 of two kinds of structures all can meet the demands, and the annular protrusion 2 of present embodiment adopts first kind of structure, and promptly the bearing of trend of annular protrusion 2 is vertical with the periphery wall bus of iron and steel body 1.
Further, said annular protrusion 2 wide 3 ~ 4mm, dark 1 ~ 1.5mm;, smooth transition between the seamed edge of annular protrusion 2, groove 3 width that form between two adjacent annular protruding 2 are suitable; The degree of depth is moderate, is convenient to aluminium water and flows to smoothly and carry out die casting in the groove 3, improves the die casting performance of cylinder sleeve.
The petrol engine cylinder sleeve of present embodiment is through being provided with annular protrusion 2 on the periphery wall of cylinder sleeve body 1, owing to have groove 3 between the adjacent annular protruding 2, the side and the bottom surface of groove 3 seamlessly transit, and aluminium water flows resistance is little; Be easy to flow in the groove 3, and the gas in the groove 3 is discharged forward, not only can not form crack and pore; And aluminum alloy and cylinder sleeve combine closely, and package power is also well guaranteed, the die casting better effects if between cylinder sleeve and the aluminum alloy; Even under the situation of cancellation cylinder sleeve preheating procedure, also can make to combine closelyr between cylinder sleeve and the aluminum alloy, be not easy to form pore; The intensity of cylinder sleeve is higher, and better quality can also be saved the energy.
Explanation is at last; Above embodiment is only unrestricted in order to the technological scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technological scheme of the utility model; And not breaking away from the aim and the scope of the utility model technological scheme, it all should be encompassed in the middle of the claim scope of the utility model.
