Abstract
A double-cooling cylinder block for an engine comprises a cylinder block casing, a cylinder liner and a cylinder heat-radiating liner, wherein a cooling water circulation cavity is arranged in the cylinder block casing; and a process opening and a seal cover are arranged on the side surface of the cylinder block casing, the process opening corresponds to the cooling water circulation cavity, and the seal cover can seal the process opening. The double-cooling cylinder block is characterized in that a column-shaped lug boss is arranged on the seal cover; a water-cooling channel is arranged in the lug boss; a water overflow port is formed on the end face of the lug boss and communicated with the water-cooling channel; and the orientation of the water overflow port is vertical to the orientation of a through hole in the cylinder liner. By the adoption of the technical scheme, the double-cooling cylinder block for the engine has the advantages of simple structure, economy, durability and long service life, the heat radiating area of the seal cover can be enlarged, and the heat radiating effect of the cylinder block of the engine can be improved.
Description
Technical field
The utility model relates to a kind of motor, particularly a kind of cylinder block.
Background technique
In the prior art, the two cold engine cylinder block of motorcycle generally comprise cylinder shell, cylinder liner and cylinder heat radiation cover, are provided with the cooling water cyclic cavity in the cylinder shell; The side of cylinder shell is provided with the sealing cover with corresponding technology opening of cooling water cyclic cavity and ability sealing technology opening; And the water-cooled area of sealing cover is less, and its heat diffusion area is little, and effect is relatively poor; Working life is short, can the radiating effect of cylinder shell be exerted an influence.
The model utility content
The purpose of the utility model just provides a kind of two cold engine cylinder block of simple in structure, long service life, and it can increase the heat diffusion area of sealing cover, improves the radiating effect of engine cylinder.
The purpose of the utility model is to realize through such technological scheme; It includes cylinder shell, cylinder liner; Be provided with the cooling water cyclic cavity in the cylinder shell; The side of cylinder shell is provided with the sealing cover with corresponding technology opening of cooling water cyclic cavity and ability sealing technology opening, it is characterized in that: the boss that is cylindricality is set on sealing cover, is provided with water cooling passageway in the boss; The end face of boss offers the mouth of a river of crossing that communicates with water cooling passageway, cross the mouth of a river towards with cylinder liner in through hole towards perpendicular.The utility model improves the cooling effect of engine cylinder through forming water cooling passageway at sealing cover to increase the heat diffusion area of sealing cover, and economy and durability has prolonged working life.
Owing to adopted technique scheme, the utlity model has the advantage of simple in structure, economy and durability and long service life, it can increase the heat diffusion area of sealing cover, improves the radiating effect of engine cylinder.
Description of drawings
The description of drawings of the utility model is following.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation that removes sealing cover among Fig. 1.
Fig. 3 is the structural representation of figure sealing cover.
Fig. 4 is the rear view of Fig. 3.
Fig. 5 is the sectional view of A-A among Fig. 3.
Among the figure: the ⒈ cylinder shell; The ⒉ cylinder liner; ⒊ cooling water cyclic cavity; ⒋ technology opening; The ⒌ sealing cover; The ⒍ boss; The ⒎ water cooling passageway; ⒏ crosses the mouth of a river; The ⒐ groove.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Shown in Fig. 1-5; Comprise cylinder shell 1, cylinder liner 2; Be provided with cooling water cyclic cavity 4 in the cylinder shell 1; The side of cylinder shell 1 is provided with the sealing cover 5 with cooling water cyclic cavity 3 corresponding technology openings 4 and ability sealing technology opening 4, it is characterized in that: the boss 6 that is cylindricality is set on sealing cover 5, is provided with water cooling passageway 7 in the boss 6; The end face of boss 6 offer communicate with water cooling passageway 7 cross the mouth of a river 8, cross the mouth of a river 8 towards with cylinder liner 2 in through hole towards perpendicular.The utility model improves the cooling effect of engine cylinder through forming water cooling passageway at sealing cover 5 to increase the heat diffusion area of sealing cover, and economy and durability has prolonged working life.
Like Fig. 4, shown in 5, water cooling passageway 7 is grooves 9 of the bar shaped of in boss 7, being offered by sealing cover 5.Can increase the area of contact of sealing cover 5 and cooling water through groove 9,, improve the cooling effect of engine cylinder to increase the heat diffusion area of sealing cover.For the ease of with cylinder head and motor on water cooling passageway be connected, the utility model can also be provided with water channel on the upper and lower end face of cylinder shell.
