Description
Technical field
The utility model relates to the motorcycle engine cylinder body, specifically, relates to a kind of double-circulation water-cooling cylinder body.
Background technique
All be cast with cooling water channel in the cylinder block and head of water-cooled engine, as the cooling-water flow passage, cooling water absorbs the heat of cylinder wall in cylinder block, and cooling water temperature raises, flow into the cooling water channel of cylinder head again, suck effluent gases cylinder cap behind the heat of cylinder head once more.The cylinder block of traditional water-cooled engine is whole, has only an annular cooling water road, has only a water intake on the annular cooling water road, and the top of cooling water channel is communicated with the water channel of cylinder head.This traditional water-cooled cylinder body, cooling water enters cooling water channel by water intake, in cooling water channel, circulate substantially and just enter cylinder head after a week, cooling water only once cools off in cylinder body, the cylinder body cooling effect is undesirable, and center housing temperature is higher, causes the cylinder body serious wear, operating life is short, changes frequent.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of double-circulation water-cooling cylinder body, and it can effectively reduce the operating temperature of cylinder body, reduces the cylinder body wearing and tearing, thereby improves the operating life of cylinder body.
The technical solution of the utility model is as follows: a kind of double-circulation water-cooling cylinder body, comprise the cylinder body body, in this cylinder body body, be provided with cooling water channel, this cooling water channel is communicated with the water channel of cylinder head, and its key is that described cooling water channel is double-deck circulation water channel, form by outer water channel and inner lead, described outer water channel ring is located at the outer wall inboard of cylinder body body, and the left and right end cap sealing that is connected with bolts at two ends by the cylinder body body forms, and has the water intake and the split-flow opening that are in communication with the outside outside described on the water channel; Described inner lead is to be opened in the annular groove of described cylinder body body middle and upper part and the inner wall outside that ring is located at described cylinder body body, between the described inside and outside water channel connecting port is arranged, cooling water water intake of water channel outside described enters and around behind the big half cycle of cylinder body body, a part flows out from described split-flow opening, and another part continues to move ahead and enters inner lead by described connecting port.
Described water intake is opened on the outer wall of described cylinder body body and with described outer water channel and is communicated with, and described split-flow opening is opened in described left and right end cap on one of them.
Outside described, between split-flow opening and water intake, be provided with in the water channel perpendicular to outside the dividing plate of water channel, on described outer water channel, offer the connecting port of the described inner lead of connection near this dividing plate
Described water intake is obliquely installed.
Described left and right end cap is provided with radiating fin.
The utility model is provided with two cooling water channels, carry out the dual cycle secondary cooling, form by cylinder body body and left and right end cap, left and right end cap is fixed by the left and right two ends of bolt and cylinder body body, the cylinder body body forms outer water channel by left and right end cap sealing back, also is equipped with inner lead in the inner wall outside of cylinder body body.During work, cooling water is water channel outside water intake enters, circulate behind the big half cycle, part cooling water flows out cylinder body through split-flow opening, take away the part heat, another part cooling water continues to enter inner lead by connecting port forward, because the cooling water in the outer water channel reduces the temperature around the cylinder body body outer side wall, and there is the part heat to discharge from split-flow opening, continue to enter existing reduction of cooling water water temperature of inner lead, the cooling water of lower temperature is circulation once more in inner lead, and cooling water absorbs near the heat the inboard wall of cylinder block and upwards enters the cylinder head water channel, thereby near the heat the inboard wall of cylinder block is taken out of, reached the purpose that reduces center housing temperature.
The beneficial effects of the utility model are: good cooling results, can effectively reduce the operating temperature of cylinder body, and reduce the cylinder body wearing and tearing, thereby improve the operating life of cylinder body.
Description of drawings
