Description
Technical field
The present invention relates to a kind of two-stroke motorcycle engine water device for cooling.
Background technique
At present, known motorcycle mainly adopts natural air cooled and mode forced air cooling that motor is cooled off with two stroke engine.Wherein because the motor of straddle type motorcycle is exposed to the outside of car body; The air-flow that in the motorcycle driving process, produces can be taken away the heat of engine producing; Reach the purpose of natural cooling, so knight's car two stroke engine of most of little discharge capacities all adopts natural air cooled structure.The pedal motorcycle two stroke engine then generally adopts the engine-driving fan to carry out the cooling structure for engine of forced air cooling owing to receive the integrally-built restriction of car load.General common motor The forced air cooling can be because of engine operating condition the abominable and more high reason of motor Environmental Conditions temperature; Exist the engine cooling deficiency to cause overheated phenomenon; Not only cause the whole output power of motor to reduce, simultaneously because the decline of combustion efficiency can cause the pollutant emission value fast rise of motor.So present stage, a lot of four-stroke motorcycle engines all adopted water-cooled mode to address this problem; But because two stroke engine and the structural difference of four stroke engine; Two stroke engine is the timing camshaft system of the output of the water pump power as the four stroke engine not, so the pedal-type two-stroke motorcycle motor of domestic production at present still cools off motor in the mode that adopts forced air cooling.
Summary of the invention
In view of the water cooling plant that does not also have at present a kind of two-stroke motorcycle motor, the present invention provides a kind of water cooling plant that adopts the two-stroke motorcycle motor of the water-cooled type of cooling.
The technological scheme that the present invention solves its technical problem is: a kind of two-stroke motorcycle engine water device for cooling; Comprise motor; Described motor comprises bent axle; Be provided with cooling water passage in the housing of described motor, an end of described cooling water passage is the engine water inlet, and the other end of said cooling water passage is the motor water outlet;
Also comprise the water pump chamber cap; Thereby described water pump chamber cap is fixed on the housing of said motor and sealing between the two forms pump chamber between the housing of water pump chamber cap and motor, and described pump chamber covers pump chamber water intake and the pump chamber water outlet that offers with described pump chamber UNICOM;
Be equipped with impeller shaft on the housing of said motor, the head of said impeller shaft stretches in the described pump chamber, and the head of said impeller shaft is provided with impeller, and the afterbody of said impeller shaft is positioned at described motor and is connected with described bent axle;
Also comprise water tank; Described water tank has filler, water outlet and backwater mouth; Pass through the first intake pipe UNICOM between described water outlet and the described pump chamber water intake; Through the second intake pipe UNICOM, pass through return pipe UNICOM between described motor water outlet and the described backwater mouth between described pump chamber water outlet and the described engine water inlet.
Further, water tank is provided with radiator.
The present invention also has following additional technical feature:
Be provided with bearing between the housing of described impeller shaft and said motor and support, seal through water-sealed component between the housing of the motor at said impeller rear and the impeller shaft.
The afterbody of said impeller shaft is provided with drive plate, and described drive plate is connected with described bent axle.
Also comprise water supply tank, pass through water-adding pipe UNICOM between described water supply tank and the described water tank.
The present invention in use, cooling water flow to pump chamber from water tank, during engine operation; Bent axle rotating band movable vane wheel shaft rotates, thus the impeller rotation, and being rotated in of impeller forms pressure in the channel system; Cooling water begins circulation; Cooling water flow is taken away the heat of engine producing when motor, thereby reaches the effect of cooling, and final cooling water is back to water tank.
Beneficial effect of the present invention is: a kind of water cooling plant of two-stroke motorcycle motor is provided, has realized the water-cooled of two-stroke motorcycle motor.
