Abstract
The utility model relates to a cylinder sleeve. The outer surface of the cylinder sleeve is uniformly provided with two layers of embossments with different heights, wherein the embossments at the upper layer are in umbrella shapes, needle shapes or mushroom shapes, and the embossments at the lower layer are in wavy shapes. In the utility model, the two layers of embossments with different heights are uniformly arranged on the outer surface of the cylinder sleeve so that the binding force between an aluminum engine cylinder and a cast iron cylinder sleeve are greatly increased, the clearance between the cylinder sleeve and a piston ring is reduced, the power of the engine is improved, and both the fuel consumption and the waste discharge are reduced. In addition, the outer circular surface of the cylinder sleeve is not needed to be machined so that the production cost is reduced.
Description
Technical field
The utility model relates to a kind of internal combustion engine part of aluminum cylinder, relates in particular to a kind of cylinder sleeve.
Background technique
In recent years, along with more and more with the strict day by day emission request of energy consumption, variation has taken place in the engine cylinder-body material now, the aluminium engine cylinder body has progressively substituted the conventional iron engine cylinder-body, make the deadweight of motor reduce significantly, reduced the consumption and the discharging wastes of fuel oil, the needs that therefore direct cylinder sleeve with cast iron quality is cast into the aluminium engine cylinder body are increasing, and the combination force of two kinds of unlike materials directly has influence on efficiency of engine.Patent No. ZL02279789.0, name is called " the uniform burr cylinder sleeve of external diameter " and discloses and a kind ofly have raised or sunkenly in the liner backs random distribution, can increase by two kinds of combination forces between unlike material, thereby improve the uniform burr cylinder sleeve of external diameter of heat-conducting property.Though this structure has increased the combination force of two kinds of materials to a certain extent, adhesive strength is not high.
The model utility content
The utility model provides a kind of cylinder sleeve that can increase aluminium engine cylinder body and Cast iron liner combination force greatly in order to overcome the above problems.
The technical solution of the utility model is: evenly be provided with the convex parts that two layer heights do not wait on the described cylinder sleeve outer surface, the upper strata convex parts is umbrella, needle-like or mushroom; Lower floor's convex parts is wavy.
Described upper strata protrusion height is 0.3-1.2mm.
Described lower floor protrusion height is 0.05-0.2mm.
The utility model has the advantages that: by the convex parts that two layer heights do not wait evenly is set on the cylinder sleeve outer surface, thereby increase the combination force between aluminium matter engine cylinder-body and the Cast iron liner greatly, dwindled the gap between cylinder sleeve and the piston ring, promoted the power of motor, the oil consumption and the discharging wastes of fuel oil have been reduced, the cylinder sleeve outer round surface does not need processing, has reduced cost of production.
Description of drawings
Fig. 1 is the structural representation of the utility model umbrella upper strata convex parts cylinder sleeve.
1 is cylinder sleeve among the figure, the 2nd, and upper strata convex parts, the 3rd, lower floor's convex parts.
Embodiment
A kind of cylinder sleeve evenly is provided with the convex parts that two layer heights do not wait on described cylinder sleeve 1 outer surface, and upper strata convex parts 2 is umbrella, needle-like or mushroom; Lower floor's convex parts 3 is wavy.Described upper strata convex parts 2 highly is 0.3-1.2mm.Described lower floor convex parts 3 highly is 0.05-0.2mm.
Important technological parameters of the present utility model is:
1, outer surface form: evenly be provided with the convex parts that two layer heights do not wait on cylinder sleeve 1 outer surface, upper strata convex parts 2 is umbrella, needle-like or mushroom, and upper strata thrust height is 0.3-1.2mm, and unit area is 10-55/cm
2Lower floor's convex parts 3 is wavy, and lower floor's thrust height is 0.05-0.2mm.
2, metallographic structure: after taking a sample to check, with the working surface of metallography microscope sem observation cylinder sleeve;
Graphite structure: according to the ASTM-A247 standard, A+E type graphite is not less than 70%, and the C type is not more than 2%, and other are B, D type.
Matrix: be fine pearlite, be not less than 95%, Free ferrite is not more than 5%, a spot of equally distributed wear-resisting phase.
3, hardness: the working surface of cylinder sleeve is measured, and scope is 90HRB-104HRB, perhaps cloth formula hardness 195-273HB.
4, Tensile strength: at cylinder sleeve cast blank body sampling, sample of 120 ° of angles of every cylinder sleeve angle of circumference amounts to three, averages more than the 230Mpa.
5, with the cylinder body adhesive strength: the cast blocks sampling, stretching rear-bank rotor housing and cylinder sleeve break away from, and intensity region is 10-40Mpa.
