Abstract
The utility model provides an air cylinder structure, which comprises a plurality of air cylinder bodies in ranging arrangement, cylinder sleeves and water sleeves, wherein the cylinder sleeves are respectively arranged in each cylinder body, the water sleeves are formed between the air cylinder bodies and the cylinder sleeves, a wall surface used for limiting the water sleeves consists of the air cylinder bodies and the cylinder sleeves, and grooves are formed on parts of the cylinder sleeves for forming the wall surfaces of the water sleeves.
Description
Technical field
The utility model relates to a kind of block structure, relates in particular to the block structure that is used for motor.
Background technique
In existing engine cylinder,, adopt aluminum alloy to constitute the main body of cylinder block mostly for alleviating the overall weight of motor.On the other hand, the wear resistance of considering aluminum alloy is relatively poor, in order to increase the wear resistance of cylinder body to piston and piston ring, wear resisting cylinder jacket is installed in cylinder body usually, as shown in Figure 4, existing cylinder block comprises: cylinder body 12, be installed in the cylinder sleeve 11 in the cylinder body 12 and be formed on cylinder body 12 and cylinder sleeve 11 between water jacket 14, the wall in the outer part of this water jacket 14 is made of cylinder body 12, wall in the inner part is made of cylinder sleeve 11.
Yet, there are two problems in the above-mentioned housing structure:
(1) because the high-temperature area (see figure 4) heat inequality of cylinder sleeve inside, and cylinder sleeve is to wait wall thickness at high-temperature area, and the heat-transfer capability of cylinder sleeve is identical in this zone, causes being heated inequality of cylinder sleeve high-temperature area and produces distortion, influences the performance of motor.
(2) because modern engine design is more and more compacter, require the distance between two cylinders more and more littler, so just cause the actual internal area of the water jacket 16 (as shown in Figure 5) between two cylinders very little, influence the heat radiation between two cylinders.
The model utility content
The purpose of this utility model is to provide a kind of block structure, can suppress the cylinder-liner distortion that causes in the inequality of being heated of high-temperature area because of cylinder sleeve, and improve the problem of arranging the too small cooling capacity deficiency of water jacket between compact two cylinders that cause because of cylinder body.
Block structure of the present utility model comprises: arrange a plurality of cylinder bodies that are provided with; Be installed in the cylinder sleeve in each cylinder body; And being formed on water jacket between cylinder body and the cylinder sleeve, the wall that is used to limit above-mentioned water jacket is made of above-mentioned cylinder body and above-mentioned cylinder sleeve, forms groove in the part of the wall of the above-mentioned water jacket of formation of above-mentioned cylinder sleeve.
In addition, the wall in the outer part of this water jacket is made of cylinder body, and wall in the inner part is made of cylinder sleeve.
According to said structure, because the part of the wall of the formation water jacket of cylinder sleeve forms groove, be that cylinder sleeve has groove with the part that water jacket (cooling liquid) contacts, therefore can increase the area of contact of cylinder sleeve and cooling liquid, increase the actual internal area of cooling liquid between two cylinders, thereby improve the cooling capacity between two cylinders.
In addition, in the above-mentioned groove, the distance of the groove distance cylinder deck of the most close cylinder cap attachment face (cylinder cap attachment face) is greater than the spacing of all the other grooves.
According to said structure, because the distance of the 1st groove distance cylinder deck (cylinder cap attachment face) of the most close cylinder cap attachment face is greater than the spacing of all the other grooves, therefore should enough big spacing can guarantee that cylinder sleeve still has good rigidity under active force, guaranteed to have good sealing property between cylinder body and the cylinder cap.
In addition, above-mentioned groove is to be concentric annulus with cylinder sleeve when overlooking.
In addition, above-mentioned groove supreme (cylinder deck) and down the degree of depth shoal gradually.
According to said structure, because groove is to be concentric annulus with cylinder sleeve when overlooking, and along with the cylinder sleeve internal heat reduces from top to down gradually, also shoal gradually to pushing up the downward annular recess degree of depth, therefore, the cooling capacity of the high-temperature zone of cylinder sleeve also reduces downwards to the top thereupon, and such design can make cylinder sleeve be heated evenly to greatest extent, reduces the deformation tendency of cylinder sleeve.

Embodiment
Below embodiment of the present utility model is elaborated.Following mode of execution only is an example of technical solutions of the utility model, should not be interpreted as the qualification to the utility model protection domain.
Fig. 1 is the sectional view of the configuration state of expression cylinder block.As shown in Figure 1, the block structure of present embodiment comprises: arrange a plurality of cylinder bodies 2 that are provided with, be installed in the cylinder sleeve 1 in each cylinder body 2, and be formed on water jacket 4 between cylinder body 2 and the cylinder sleeve 1,6 (water jacket 4 is formed between cylinder body 2 and the cylinder sleeve 1, water jacket 6 is formed between cylinder sleeve and the cylinder sleeve), be used to limit water jacket 4,6 wall is made of cylinder body 2 and cylinder sleeve 1 that (wall that limits water jacket 4 is made of cylinder body 2 and cylinder sleeve 1, the wall that limits water jacket 6 constitutes by cylinder sleeve 1), at the formation water jacket 4 of cylinder sleeve 1, the part of 6 wall forms groove S.
As shown in Figure 1, in the present embodiment, the wall in the outer part of this water jacket 4 is made of cylinder body 2, and wall in the inner part is made of cylinder sleeve 1.
Groove S is concentric annulus with cylinder sleeve 1, and supreme (cylinder deck) and down the degree of depth shoal gradually.
Fig. 3 is the sectional view of structure of the cylinder sleeve of expression block structure.As shown in Figure 3, among these grooves S, the 1st groove S of the most close cylinder cap 5 attachment faces is apart from the distance L 1 of cylinder deck (cylinder cap attachment face) the spacing L2 greater than all the other grooves.
Structure according to present embodiment, because the part of the wall of the formation water jacket 4 of cylinder sleeve 1 forms groove S, be that cylinder sleeve 1 has groove S with the part that water jacket 4 (cooling liquid) contacts, therefore can increase the area of contact of cylinder sleeve and cooling liquid, increase the actual internal area of cooling liquid between two cylinders, thereby improve the cooling capacity between two cylinders.Fig. 2 is the sectional view of the configuration state between expression two cylinder block, can be well understood to the form that the circulation between two cylinders cuts by Fig. 2.
Structure according to present embodiment, because the 1st groove S of the most close cylinder cap 1 attachment face is apart from the distance of cylinder body 1 end face (cylinder cap attachment face) spacing greater than all the other grooves, therefore should enough big spacing can guarantee that cylinder sleeve still has good rigidity under active force f1, f2, guaranteed to have good sealing property between cylinder body and the cylinder cap.
Structure according to present embodiment, because groove S is concentric annulus with cylinder sleeve, and along with the cylinder sleeve internal heat reduces from top to down gradually, also shoal gradually to pushing up the downward annular recess degree of depth, therefore, the cooling capacity of the high-temperature zone of cylinder sleeve also reduces downwards to the top thereupon, and such design can make cylinder sleeve be heated evenly to greatest extent, reduces the deformation tendency of cylinder sleeve.
