Abstract
The invention relates to a cooling device for an engine piston of a motorcycle. The cooling device comprises a cylinder block and the piston arranged in the cylinder block. The piston is connected with a crankshaft connecting rod assembly which is arranged in a crankshaft case. An annular oil pipe is arranged in the crankshaft case, located above the piston and provided with a plurality of oil spray nozzles. According to the cooling device for the engine piston of the motorcycle, the oil spray nozzles are arranged on the annular oil pipe to spray cooling oil to the piston, the cooling effect on the piston is greatly improved, and meanwhile the lubricating effect between the piston and the cylinder block is also improved.
Description
Technical field
The present invention relates to a kind of motorcycle engine piston cooling unit.
Background technique
The patent No. be 201320352629.3 Chinese patent disclose a kind of motorcycle engine piston cooling unit, comprise cylinder body, piston, crankshaft-link rod assembly and crankcase, piston is arranged in cylinder body, piston is connected with crankshaft-link rod assembly, crankshaft-link rod assembly is arranged at the inner chamber of crankcase, is provided with the oil nozzle be connected with oil pipe, during engine operation in crankcase, oil nozzle sprays cold oil to piston, plays the effect of cooling piston.Although this cooling unit has certain cooling action to piston, owing to only having an oil nozzle to spray cold oil to piston, therefore, the cooling effect of piston is bad.
Summary of the invention
The object of the present invention is to provide a kind of motorcycle engine piston cooling unit of good cooling results.
The object of the present invention is achieved like this, a kind of motorcycle engine piston cooling unit, the crankshaft-link rod assembly comprising cylinder body and be arranged on piston in cylinder body, crankcase and be arranged in crankcase, piston is connected with crankshaft-link rod assembly, fuel ring pipe is provided with in crankcase, fuel ring pipe is positioned at above piston, and fuel ring pipe is provided with multiple oil nozzle.During engine operation, the multiple oil nozzles on fuel ring pipe spray cold oil facing to piston, improve the cooling effect of piston.
In order to make cold oil be distributed in piston uniformly, improve cooling effect further, oil nozzle is distributed on fuel ring pipe.
In order to simple and compact for structure, fuel ring pipe is arranged on the inwall of crankcase.
The cold oil sprayed in order to the oil nozzle ensured on fuel ring pipe is all ejected on piston, and the external diameter of fuel ring pipe is not more than the diameter of piston.
Fuel ring pipe is provided with filler opening, and filler opening is connected with the oil duct that crankcase is arranged.
Oil duct is connected with fuel tank.
The present invention has following beneficial effect:
1, motorcycle engine piston cooling unit of the present invention arranges fuel ring pipe in crankcase, above piston, sprays cold oil by multiple oil nozzles that fuel ring pipe is arranged to piston, has increased substantially the cooling effect of piston.
2, motorcycle engine piston cooling unit of the present invention has the function of piston being carried out to Cooling and Lubricator concurrently simultaneously, not only increases the cooling effect to piston, and improves the lubrication effect to piston.
3, structure of the present invention is simple, is easy to realize.
