Abstract
The utility model discloses an engine aluminium alloy cylinder liner wherein the outer surface of the cylinder liner (1) is provided with a continuous arc-shaped spiral groove (3) along the axial direction. In the utility model, the arc-shaped spiral groove is arranged on the outer surface of the cylinder liner, the cylinder liner uses the groove to be die-casted in the cylinder body, in die-casting, the aluminium alloy liquid is pressed into the groove to form a bulge which not only can be matched with the groove to improve the binding ability of the cylinder liner, but also can increase the contact area between the cylinder liner and the cylinder body and improve the heat dispersion of the cylinder liner. In addition, the cylinder liner has simple structure and convenient processing, and can reduce the manufacturing cost.
Description
Technical field
The utility model relates to engine art, especially relates to a kind of engine aluminum alloy cylinder sleeve.
Background technique
On motor, generally cylinder sleeve is manufactured independent cylindrical component, and then be installed in the cylinder block now.Like this, cylinder sleeve can adopt wear-resisting quality material to make, and cylinder block is the lower general made of available rates then, thereby has reduced manufacture cost.Because the thermal expansion coefficient of cylinder sleeve and cylinder block is different, cylinder sleeve and cylinder block takes place easily in conjunction with bad problem, more seriously then the fault that cylinder sleeve comes off can take place.The Chinese utility model patent specification of the CN2576980Y that on October 1st, 2003 was announced discloses the uniform burr cylinder sleeve of a kind of external diameter, this cylinder sleeve outer surface random distribution is jagged, in order to improve the coating performance of cylinder sleeve and aluminum alloy cylinder body, this design can improve coating performance to a certain extent, but after having used a period of time, still can occur in conjunction with condition of poor, and the fitting area of cylinder sleeve and cylinder block is less than normal, causes radiating effect not good.
The model utility content
The utility model mainly is to solve existing cylinder sleeve and cylinder block binding ability and the not good problem of heat dispersion in the prior art, a kind of engine aluminum alloy cylinder sleeve is provided, this cylinder sleeve can improve the binding ability of cylinder block and cylinder sleeve, and improves its heat dispersion.
For solving the problems of the technologies described above, the utility model has adopted a kind of like this engine aluminum alloy cylinder sleeve, at the outer surface of this cylinder sleeve continuous arc helical groove is set vertically.Cylinder sleeve passes through the die casting of arc helical groove in cylinder block like this, aluminum alloy liquid is pressed into arc helical groove continuous on the cylinder sleeve outer surface during die casting, just form the projection of spiral on the junction plane of cylinder sleeve and cylinder block, arc helical groove and projection interlock mutually, improved the combination force between cylinder sleeve and the cylinder block, and increased the area of contact of cylinder sleeve and cylinder block, improved the heat dispersion of cylinder sleeve.
As preferably, the radius of arc helical groove is 1.5mm～2mm; The degree of depth is 0.35mm～0.5mm; Spacing is 5mm～7mm.Design can well guarantee binding ability and heat dispersion between cylinder sleeve and the cylinder block on the basis that reduces difficulty of processing and cost like this.
The utility model is provided with the arc helical groove at the outer surface of cylinder sleeve, and cylinder sleeve utilizes this groove die casting in cylinder block, and aluminum alloy liquid is pressed into groove during die casting, forms projection.This projection not only can improve the binding ability of cylinder sleeve with groove fit, and has increased the area of contact between cylinder sleeve and the cylinder block, has improved the heat dispersion of cylinder sleeve.This model utility is simple in structure, easy to process in addition, can reduce manufacture cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation after cylinder sleeve of the present utility model and the cylinder block die casting.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, at cylinder sleeve 1 outer surface continuous arc helical groove 3 is set, in order to reduce difficulty of processing and cost, the radius of this arc groove is advisable with 1.5mm～2mm, is preferably 1.8mm; The degree of depth is advisable with 0.35mm～0.5mm, is preferably 0.4mm; Spacing is advisable with 5mm～7mm, is preferably 6mm.
As shown in Figure 2, in cylinder block 2, aluminum alloy liquid flows into groove during die casting with cylinder sleeve 1 die casting, solidifies exhaust casing cover 1 and is cast into one with cylinder block 2.At this moment the aluminum alloy melt bodies in the groove 3 form projection 4, and engaged with the groove 3 on cylinder sleeve 1 outer surface, have increased the combination force between cylinder sleeve 1 and the cylinder block 2, make between cylinder sleeve 1 and the cylinder block 2 binding ability better.Interlock has also increased the area of contact between cylinder sleeve 1 and the cylinder block 2 between projection 4 and the groove 3, and the heat dispersion of cylinder sleeve 1 improves when making engine operation.
Claims (4)
