Abstract
The utility model relates to a water pump structure for a water-cooling motorcycle engine and provides a separating type water pump used for a water-cooling motorcycle engine. The separating type water pump used for the water-cooling motorcycle engine mainly comprises a water pump cover (1), a water pump body (4), a water pump impeller (2) and a water pump shaft (3), wherein the water pump shaft (3) is connected with the water pump impeller (2); the water pump body (4) is connected to a right crankcase cover (8) of the engine to form a separable structure; the water pump shaft (3) passes through the center of the water pump body (4) and the right crankcase cover (8); a water seal (5) is arranged between the water pump shaft (3) and the water pump body (4); an oil seal (7) is arranged between the water pump shaft (3) and the right crankcase cover (8); and a cavity used for releasing leaked cooling liquid is formed between the water pump body (4) and the right crankcase cover (8). According to the water pump structure for the water-cooling motorcycle engine, the cooling liquid is effectively prevented from entering the engine. Meanwhile, the water seal, the water pump shaft and the oil seal have the same axis to transfer the revolving speed, and the sealing effect is guaranteed.
Description
Technical field
The utility model relates to the water pump mechanism of cooling motorcycle engine water, is specifically related to a kind of cooling motorcycle engine water and uses the separated type water pump.
Background technique
At present, the water pump chamber of vertical water cooled engine is arranged in right crankcase and covers, and water seal, oil sealing are installed in right crankcase cover inside; Cooling liquid and lid portion inside machine oil is isolated, because motor is worked for a long time, possibly cause water pump seal, oil sealing wearing and tearing; High-pressure coolant in the water pump can be revealed, and the part cooling liquid gets into engine interior, causes lubricating oil emulsion; Lose lubrication, cause key components and partss such as engine cylinder-body, piston to can not get lubricating, take place badly damaged.When maintenance, owing to water seal, oil sealing are installed in right crankcase cover inside, dismounting is extremely inconvenient again.
Summary of the invention
For solving the problems of the technologies described above, the utility model purpose is to propose a kind of cooling motorcycle engine water to use the separated type water pump.
The utility model goal of the invention can adopt following technological scheme to realize:
A kind of cooling motorcycle engine water is used the separated type water pump, and described separated type water pump mainly comprises water pump cover, water pump body, water pump vane and the water pump spindle that is connected with water pump vane; Described water pump cover connects firmly the end at water pump body, and the cavity between water pump cover and the water pump body constitutes in order to place the water pump chamber of cooling liquid; Described water pump vane is positioned at water pump cover and the formed water pump of water pump body chamber; The right crankcase that the other end of said water pump body is connected motor covers formation water pump body and the separable structure of right crankcase cover; The said water pump spindle that is connected with water pump vane passes the center of water pump body and right crankcase cover; And between water pump spindle and water pump body, be provided with in order to the water seal with water pump cover and the sealing of the formed water pump of water pump body chamber, the oil sealing in order to the machine oil sealing is set between water pump spindle and right crankcase cover; The groove that on the junction plane of water pump body and right crankcase cover, has lower ending opening forms the cavity that discharges in order to the cooling liquid of leaking between groove that said water pump body had and the right crankcase cover.
A kind of cooling motorcycle engine water that the utility model proposes is used the separated type water pump, and water pump body and right crankcase cover are separable, and has the cavity that discharges cooling liquid between the two, has avoided cooling liquid to get into engine interior effectively; Water pump spindle passes the center of water pump body and right crankcase cover; And between water pump spindle and water pump body, be provided with in order to water seal with water pump cover and the sealing of the formed water pump of water pump body chamber; Oil sealing in order to the machine oil sealing is set between water pump spindle and right crankcase cover; Make water seal, water pump spindle, oil sealing concentric, realized the transmission of rotating speed, guaranteed sealing simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, water pump cover, 2, water pump vane, 3, water pump spindle, 4, water pump body, 5, water seal, 6, locating stud, 7, oil sealing, 8, right crankcase cover.
Embodiment
In conjunction with accompanying drawing, the specific embodiment of the utility model is described.
As shown in Figure 1: a kind of cooling motorcycle engine water is used the separated type water pump, and described separated type water pump mainly comprises water pump cover 1, water pump body 4, water pump vane 2 and the water pump spindle 3 that is connected with water pump vane 2; Described water pump cover 1 connects firmly the end at water pump body 4, and the cavity between water pump cover 1 and the water pump body 4 constitutes in order to place the water pump chamber of cooling liquid; Described water pump vane 2 is positioned at water pump cover and the formed water pump of water pump body chamber; The other end of said water pump body 4 is connected through locating stud 6 and constitutes water pump body 4 and right crankcase cover 8 separable structures on the right crankcase cover 8 of motor; One end of said water pump spindle 3 is threaded with water pump vane 2; The other end passes the center of water pump body 4 and right crankcase cover 8; And between water pump spindle 3 and water pump body 4, be provided with in order to the water seal 5 with water pump cover and the sealing of the formed water pump of water pump body chamber, the oil sealing 7 in order to the machine oil sealing is set between water pump spindle 3 and right crankcase cover 8; The groove that on the junction plane of water pump body 4 and right crankcase cover 8, has lower ending opening forms the cavity that discharges in order to the cooling liquid of leaking between groove that said water pump body 4 is had and the right crankcase cover 8; When long-term work water seal 5 wearing and tearing take place to leak; The cooling liquid of revealing through water seal 5 can not enter into engine interior through oil sealing 7; But directly be excreted to external engine through the cavity between water pump body 4 and the right crankcase 8, guaranteed the machine oil quality of engine interior, greasy property.
