Description
Technical field
The utility model belongs to the motorcycle engine technical field, relates generally to a kind of motorcycle water-cooled formula engine water pump structure.
Background technique
At present, domestic motorcycle water-cooled formula engine water pump structure has two kinds usually: a kind of is to be arranged in the right lid, is driven by one group of engaging gear by bent axle.The shortcoming of this structure is: cause right lid complex structure, dismounting inconvenience; In addition, be subjected to the oil filter structural limitations, the pump water yield of water pump also is difficult to improve, and causes the cooling effect of motor poor.Another kind also is to be arranged in the right lid, is driven by one group of engaging gear by clutch.The shortcoming of this structure is: the two-stage transmission causes velocity ratio to reduce, and mechanical efficiency reduces, and the lubricating condition of water pump is bad, makes that the cooling effect of motor is poor.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to propose a kind of motorcycle water-cooled formula engine water pump structure, make its have the water-cooling structure position rationally, the characteristics of convenient, the good cooling results of compact structure, installation, maintenance.
The utility model is finished the technological scheme that its invention task taked: a kind of motorcycle water-cooled formula engine water pump structure mainly comprises water pump complement, left crankcase, trunnion shaft; Described water pump complement comprises water pump vane, water pump cover, the bolt that discharges water, water intake and water outlet; Described water pump cover with dewatering orifice is fixed on the left crankcase, and is provided with sealing gasket between water pump cover and left crankcase, constitutes the water pump chamber of sealing; The described water pump vane that is positioned at the water pump chamber is fixed on an end of trunnion shaft by screw, packing ring, the other end of trunnion shaft passes left crankcase and is meshed by corresponding gear on gear and the bent axle, constitutes the structure that water pump vane rotates with the rotation of bent axle; The described bolt that discharges water is installed in the dewatering orifice of water pump cover, and between bolt and the dewatering orifice copper washer is set discharging water.
Described water intake is positioned on the water pump cover.
Described water outlet is positioned on the left crankcase.
A kind of motorcycle water-cooled formula engine water pump structure that the utility model proposes, have the water-cooling structure position rationally, the characteristics of compact structure, easy for installation, good cooling results, and the bolt convenient for maintaining that discharges water is set in the dewatering orifice.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional drawing of Fig. 1.
Fig. 3 is the B-B sectional drawing of Fig. 1.
Among the figure: 1, water pump cover, 2, water pump vane, 3,8, screw, 4, sealing gasket, 5, left crankcase, 6, trunnion shaft, 7, water intake, 9, packing ring, 10, the water pump chamber, 11, water seal, 12, bearing, 13, the bolt that discharges water, 14, copper washer, 15, water outlet.
Embodiment
With embodiment the utility model is illustrated in conjunction with the accompanying drawings:
A kind of motorcycle water-cooled formula engine water pump structure mainly comprises water pump complement, left crankcase 5, trunnion shaft 6; Described water pump complement comprises water pump vane 2, water pump cover 1, the bolt 13 that discharges water, water intake 7 and water outlet 15; Described water pump cover 1 with dewatering orifice is fixed on the left crankcase 5 by three screws 3, and is provided with sealing gasket 4 between water pump cover 1 and left crankcase 5, constitutes the water pump chamber 10 of sealing; The described water pump vane 2 that is positioned at water pump chamber 10 is fixed on an end of trunnion shaft 6 by screw 8, packing ring 9, the water pump axis hole that the other end of trunnion shaft 6 passes on the left crankcase 5 is meshed by corresponding gear on gear and the bent axle, constitutes the structure that water pump vane 2 rotates with the rotation of bent axle; The described bolt 13 that discharges water is installed in the dewatering orifice of water pump cover 1, and copper washer 14 is set discharging water between bolt 13 and the dewatering orifice; Described water intake 7 is positioned on the water pump cover 1; Described water outlet 15 is positioned on the left crankcase 5.
In engine operation process, trunnion shaft 6 is being with water pump vane 2 to rotate together by crank-driven, and the rotating speed of its rotating speed and bent axle is the same; Water pump vane 2 can suck cooling water from the water intake 7 on the water pump cover 1, the water outlet 15 from left crankcase 5 is discharged, and finishes the circulation of cooling water and then the cooling action of motor thereby cooling water is sent into cooling system; When service engine need discharge water to water pump, only need twist the bolt 13 that discharges water, remove copper washer 14, cooling water can flow out from water channel fully, waits cooling water all to flow out, and discharge water bolt 13 and copper washer 14 are screwed on gets final product again, makes things convenient for engine maintenance.
