Abstract
The utility model discloses a motorcycle water -cooling engine cylinder block, including cylinder body body (1), be provided with cylinder body water jacket (2) in cylinder body body (1) cylinder body water jacket (2) endotheca is equipped with cylinder liner (3) the outer wall of cylinder liner (3) is provided with the heat dissipation protruding portion, the heat dissipation protruding portion is connected with cylinder body water jacket (2) embedded type. The utility model has the advantages of simple structure, convenient, the low cost of manufacturing, adopt it can increase the heat radiating area of cylinder liner, reduce the heating load, improve the pressure scaling of engine for the complete machine thermal efficiency improves, and fuel combustion is abundant, and power is sufficient.
Description
Technical field
This utility model relates to a kind of engine cylinder-body, particularly a kind of motorcycle water-cooled engine cylinder block.
Background technology
At present, in engine art, cylinder block is the main element of electromotor, and cylinder and crankcase are connected by it, is the support framework installing piston, bent axle and other part and accessories.Wherein, the working condition of cylinder block is very severe.It to bear the strong friction of sharply change and the piston movement of pressure and temperature in combustion process.Therefore, it should have following performance:
1. there are enough strength and stiffness, deform little, it is ensured that each moving parts position is correct, works well, and vibration noise is little.
2. there is good cooling performance.
3. wear-resisting, to ensure that cylinder block has enough service life.
In order to make cylinder surfaces at high temperature normal operation, it is necessary to cylinder and cylinder head are suitably cooled down.First current cooling means has two kinds, and one is water-cooled, and another kind is air-cooled.Around the cylinder of water-cooled engine, processing has cooling jacket, and cylinder block and cylinder head cooling jacket communicate, and cooling water constantly circulates in cylinder body water jacket, takes away partial heat, cylinder and cylinder head are risen cooling effect.But, it is that surface contacts owing to being cylinder sleeve with cylinder body water jacket, cylinder body water jacket and cylinder sleeve are respectively provided with certain thickness, cause that radiating effect is undesirable so that the compression ratio of electromotor does not reach designing requirement, and fuel oil burning is insufficient, and power is poor.
Utility model content
The purpose of this utility model is just to provide the motorcycle water-cooled engine cylinder block of a kind of good cooling results.
The purpose of this utility model is realized by such technical scheme, a kind of motorcycle water-cooled engine cylinder block, including cylinder body body, at described cylinder body, this internal is provided with cylinder body water jacket, it is arranged with cylinder sleeve in described cylinder body water jacket, outer wall at described cylinder sleeve is provided with heat dissipation protrusions, and described heat dissipation protrusions is connected with cylinder body water jacket inserted type.
Wherein, described heat dissipation protrusions is the multiple raised lines being vertically arranged on outer wall of cylinder jachet, and the inwall at described cylinder body water jacket is provided with the groove coordinated with raised line.
Further describing, the length of described raised line is less than or equal to the height of cylinder body water jacket.
Owing to have employed technique scheme, this utility model has simple in construction, advantage easily manufactured, with low cost, adopts it can increase the area of dissipation of cylinder sleeve, reduce thermic load, improve the compression ratio of electromotor so that the complete machine thermal efficiency improves, fuel oil sufficient combustion, power is sufficient.
Accompanying drawing explanation
Accompanying drawing of the present utility model illustrates as follows:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the A-A sectional view of Fig. 1；
Fig. 3 is the B-B sectional view of Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail; but this utility model is not limited to these embodiments; any improvement on the present embodiment essence spirit or replacement, still fall within this utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, 2, 3, a kind of motorcycle water-cooled engine cylinder block, including cylinder body body 1, it is provided with cylinder body water jacket 2 in described cylinder body body 1, it is arranged with cylinder sleeve 3 in described cylinder body water jacket 2, outer wall at described cylinder sleeve 3 is provided with heat dissipation protrusions, and described heat dissipation protrusions is connected with cylinder body water jacket 2 inserted type.
Wherein, described heat dissipation protrusions is the multiple raised lines 4 being vertically arranged on cylinder sleeve 3 outer wall, and the inwall at described cylinder body water jacket 2 is provided with the groove 5 coordinated with raised line 4.
Further, the length of described raised line 4 is less than or equal to the height of cylinder body water jacket 2.
In this utility model, enable to the contact area between cylinder sleeve 3 and cylinder body water jacket 2 by raised line 4 and increase, meanwhile, reduce the thickness between cylinder sleeve 3 and cylinder body water jacket 2 so that radiating effect is better.Cylinder sleeve 3 outer wall arranges raised line 4 and can increase the action of turbulent flow of water, it is ensured that the temperature constant of cylinder body body 1 each several part, and, raised line 4 also has the intensity strengthening cylinder sleeve 3, it is to avoid the deformation of cylinder sleeve 3, reduces leak rate.
Claims (3)
