Background technology
Heart of the motorcycle engine as motorcycle, drives the motion of motorcycle, and engine includes piston/cylinder, built-in
In the piston in piston/cylinder, crankshaft-link rod component and crankcase, the crankshaft-link rod component is done under the driving of piston to be rotated
Motion, and outside wheel is delivered to by bindiny mechanism, band motor car wheel rotates.Because piston is between reciprocating motion and cylinder
The heat of friction and the burning of engine inner combustion chamber all make it that the temperature of piston is very high, and piston temperature is too high easily to cause piston
Service life reduce, and increase pollutant discharge and produce noise.Currently used engine cooling method is by flying
Machine oil is splashed to cool down, and this mode, it is difficult to which the machine oil in crankcase is splashed on piston, causes piston when low-medium speed is run
It can not cool down or cooling effect is bad, piston, piston pin, connecting rod is born severe work circumstances.

It is connected in cavity and with piston, cooling oil duct is provided with described crankcase wall, the jet of the cooling oil duct is set
Below piston, the cooling oil duct is connected with hydraulic pump, cooling oil is ejected on piston, to cool down piston and bent to lower section
Axis bar lubricates；The hydraulic pump oil inlet connects fuel tank, and the fuel tank is connected with crankcase to reclaim cooling oil in time.
As the improvement of above-mentioned technical proposal, check valve is provided with the cooling oil duct to be prevented fluid from flowing back and makes fluid
Ejection has certain pressure.
As the further improvement of above-mentioned technical proposal, the hydraulic pump is gear pump, is arranged on outside crankcase, the tooth
The driving wheel of wheel pump is connected and is driven by it with bent axle rod member.
Further, the hydraulic pump is vane pump, is arranged on outside crankcase, the blade pump rotor and the bent axle rod member
Connect and be driven by it.
Further, the cooling oil duct includes circulating line, and has multiple in the jet and be distributed on the annular
On pipeline.
The beneficial effects of the invention are as follows：A kind of motorcycle engine piston cooling device of the present invention, i.e., under described piston
Portion is provided with cavity, and to accelerate cooling, the bent axle rod member is extended in cavity and is connected with piston, described crankcase
Cooling oil duct is provided with wall, cooling oil duct is not take up crankcase space and reaches the protection to cooling oil duct, it is described cold
But the jet of oil duct is arranged on below piston, and the cooling oil duct is connected with hydraulic pump, cooling oil is ejected on piston, with
Cool down piston and lower section bent axle rod member is lubricated；The hydraulic pump oil inlet connects fuel tank, the fuel tank connected with crankcase with
Recovery cooling oil in time.
