Abstract
The utility model relates to an engine oil cooler, which is installed in a motorcycle having a forced air cooling engine. The motorcycle is provided with a cooling fan driven by a crank shaft, the fan is provided with a fan cover, and an engine cylinder and a cylinder head is coated in an engine cover cap. The oil cooler is arranged in an enclosed space covered by the fan cover and the engine cover cap. The fresh cooling air is sucked, and is flowed across the oil cooler through the fan cover and the engine cover cap. The machine oil is forced to be cooled, and the cylinder head are also cooled. Hot air is exhausted from the exit of the engine cover cap.
Description
The utility model relates to a kind of machine oil cooler that is loaded on the motorcycle with forced air cooling engine, refers in particular to simple structure, shortens oil circuit and saves the space and can reach the machine oil cooler of cooling effect.
The engine of four-journey forced air cooling engine and oil temperature are too high, often cause engine to bring into play performance and influence engine efficiency, so the standing machine oil cooler of putting.Known machine oil cooler designs in the protecgulum of machine motorcycle more, because of cooler is settled complicated, and shortcoming such as oil circuit is with high costs apart from the engine oil circuit of too far having derived.
The purpose of this utility model is to provide a kind of can shorten oil circuit, construct simple and easy, as to save space new oil cooler.
Above-mentioned purpose is realized by machine oil cooler of the present utility model, this forced air cooling engine has the engine cover cap, cylinder, the cooling fan of crankshaft drives and fan cover, cylinder and crankshaft drives fan are positioned at this engine cover cap and the formed confined space of this fan cover, wherein, machine oil cooler is installed on fan, in the space that cylinder and fan cover surrounded, the cool air of fan institute suction is by this engine cover cap and the guiding of fan cover enclosed space, this machine oil cooler outside of flowing through earlier, force cooling machine oil, flow through cylinder again, cooling engine covers the outlet of being reserved by hood at last and discharges outside the engine.
The hot machine oil of crankcase is entered machine oil cooler by oil pump along the machine oil input oil pipe, and the machine oil after chilled air cools flows back to crankcase by the machine oil output oil pipe again, so constantly circulation, and reach the purpose of cooling machine oil.And the material of machine oil cooler can be various metals with high heat-conduction coefficient, as die casting aluminium or copper pipe.
Machine oil cooler of the present utility model because of fan with crankshaft drives, its rotating speed is identical with engine speed, the flow of cool air also changes with engine speed and regulates automatically, therefore not only can reach the effect of cooling machine oil, advantages such as also having simple structure concurrently, shorten oil circuit and save the space and then reduce cost.
Below, be described with reference to the accompanying drawings the embodiment of the utility model cooler, wherein:
Fig. 1 is scooter-type motorbike engine portion and cooling fan portion side sectional view;
Fig. 2 is the structural representation of scooter-type motorbike engine portion and the rotation of cooling fan small angle;
Fig. 3 is the structural representation that machine oil cooler that die casting aluminium is made is installed on cooling fan portion;
Fig. 4 is the structural representation that machine oil cooler that aluminum pipe is made is installed on cooling fan portion.
As shown in Figures 1 and 2, machine oil cooler 5 of the present utility model is placed in a scooter-type motorbike engine 1 and a cooling fan mechanism 2 formed enclosed spaces, and is positioned at before the cylinder head 4.This cooling fan mechanism 2 is flabellum 9 rotations that driven cooling fan by the crankshaft 14 of engine driving, and the fan cover ventilated port 11 of cool air by fan cover 12 sucked.Machine oil cooler 5 is extracted out machine oil by oil pump (not shown), the oil circuit via crankcase (not shown) is transported to bolt 8 again, and enters machine oil input oil pipe 6 by the oilhole of bolt 8, the machine oil cooler 5 of flowing through at last.At this moment, the enclosed space that the cooling air that is sucked by fan is defined through engine cover cap 13 and fan cover 12, blow to this machine oil cooler 5 outsides, to reduce its temperature, and reach cooling effect, and then blow to cylinder 3 and cylinder head 4 in leading the way, and make engine 1 cooling, discharge hot air by the outlet of this engine cover cap 13 at last.Simultaneously, cooled machine oil output oil pipe 7 flows back to the oil-way system of crankcase.
The embodiment as shown in Figures 3 and 4 and the embodiment of Figure 1 and Figure 2 are similar, and only with the material and the alteration of form of its machine oil cooler 5, embodiment shown in Figure 3 is with die casting aluminium with radiating fin material as machine oil cooler 5.And in Fig. 4, be with the copper pipe bending, and machine oil is mobile in pipe, and be fixed on the cylinder with bolt 15, produce noise and fracture to avoid vibration.
Claims (3)
1, a kind of machine oil cooler, be installed in the motorcycle with forced air cooling engine, motorcycle has the cooling fan of crankshaft drives, cooling fan has fan cover, the cylinder of engine and cylinder head are coated in the engine cover cap, it is characterized in that: machine oil cooler is arranged in the confined space that this fan cover and this engine cover cap coated, fresh cooling air is sucked outside this fan cover by this cooling fan, through fan cover and engine cover cap and this machine oil cooler of flowing through, force cooling machine oil, the cylinder of cooling engine and cylinder head again, and by the outlet of engine cover cap hot air is discharged.
2, machine oil cooler as claimed in claim 1, the material that it is characterized in that machine oil cooler is a die casting aluminium.
3, machine oil cooler as claimed in claim 1 is characterized in that machine oil cooler is to be made of the copper pipe bending.
