Abstract
The utility model discloses a case body structure of an oil cooling type motor cycle engine. In a right crankshaft case body thereof, a cooled machine oil guide groove is arranged between a via hole of a positive chain and a mounting hole for an air cylinder sleeve, the inlet of the cooled machine oil guide groove is communicated with the air cylinder oil way, the outlet of the cooled machine oil guide groove penetrates through one case body wall of the positive chain mounting surface of the right crankshaft case body, one side wall of the outlet of the cooled machine oil guide groove is connected with a flow guide wall communicated with an oil tank of the crankshaft case body, and the flow guide wall separates the outlet of the cooled machine oil guide groove and a crankshaft whole dummy club. The cooled machine oil guide groove takes the shape of a flat funnel with larger upper part and smaller lower part, and the flow guide wall takes the shape of a bent plate and is covered over the crankshaft bearing. The utility model ensures the cooled machine oil passing through the air cylinder head and the air cylinder body to pass through the cooled machine oil guide groove and then backflow to the oil tank of the crankshaft case body along the flow guide wall finally, and prevents impurities of iron chips and the like in the machine oil from flowing inside, thereby effectively protecting the operation performance of the engine and prolonging the service life of the engine.
Description
Technical field
The utility model relates to a kind of crankcase body structure of motorcycle engine, relates in particular to a kind of right crankcase body structure of oil injection type motorcycle engine.
Technical background
In traditional oil cooling motor, be back in the crankcase by the timing chain via hole after cooling machine oil cooling down high-temperature cylinder head, the cylinder block.In this process, the component that a large amount of machine oil directly wash away timing chain, bent axle and cooperate with it, make the impurity such as iron filings in the machine oil directly go in the above-mentioned parts, gently then cause timing chain, bent axle, and the wearing and tearing of the component that cooperate with it, heavy then cause above-mentioned parts running stuck, thus make the usability of motor reduce lifetime.
The model utility content
During the utility model in order to overcome the deficiencies in the prior art, aim to provide a kind of housing structure of oil injection type motorcycle engine, the structure of right crankcase particularly, this structure can avoid a large amount of cooling machine oils directly to wash away timing chain, bent axle in crankcase body inside, and the component that cooperate with it, prevent that the iron filings in the machine oil from entering in it, thereby effectively guarantee the usability of motor, prolong motor working life.
The utility model is achieved through the following technical solutions: a kind of housing structure of oil injection type motorcycle engine, comprise right crankcase, on the mating face of right crankcase and cylinder block, be provided with timing chain via hole and cylinder mounting hole of cylinder sleeve, described right crankcase is provided with the cooling machine oil guide groove between timing chain via hole and cylinder mounting hole of cylinder sleeve, the cooling machine oil entry guide communicates with the cylinder block oil circuit, the outlet of cooling machine oil guide groove connects timing chain attachment face one side box body wall of right crankcase, described cooling machine oil guide groove exports a sidewall and is connected to the training wall that is communicated with the crankcase body oil sump, and training wall separates the outlet of cooling machine oil guide groove on its both sides with the crankshaft hole boss.The flat funnel-like that aforesaid cooling machine oil guide groove is big up and small down, this training wall is the bent plate shape, hides in top, crankshaft bearing position.
The utility model is by the ingenious transformation to right crankcase; make cooling machine oil pass through described cooling machine oil guide groove again along training wall by cylinder head, cylinder block; be back to the crankcase body oil sump at last; avoided machine oil when the timing chain via hole passes through; connect and wash away timing chain, bent axle, and the component that cooperate with it, prevented that the impurity such as iron filings in the machine oil from entering in it; thereby effectively protect the usability of motor, prolong the working life of motor.

Fig. 2 be among Fig. 1 P to view,
Fig. 3 is the A-A partial sectional view of the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of housing structure of oil injection type motorcycle engine, as shown in Figure 1, comprise right crankcase 1, on the mating face of right crankcase 1 and cylinder block, as shown in Figure 2, be provided with timing chain via hole 2 and cylinder mounting hole of cylinder sleeve 3, between timing chain via hole 2 and cylinder mounting hole of cylinder sleeve 3, be provided with a cooling machine oil guide groove 4, as shown in Figure 3, the flat funnel-like that cooling machine oil guide groove 4 is big up and small down, the inlet 5 of cooling machine oil guide groove 4 communicates with the cylinder block oil circuit, and the outlet 6 of cold oil flow path groove 4 connects formal chain attachment face one side box body wall of right crankcase.Outlet 6 one sidewalls of cooling machine oil guide groove 4 are connected to the training wall 7 that is communicated with the crankcase body oil sump, and this training wall 7 hides in top, crankshaft bearing position for the bent plate shape, and the outlet 6 and the crankshaft hole boss of cooling machine oil guide groove separated on its both sides.
In engine working process, the cooling machine oil in the cylinder block enters cooling machine oil guide groove 4 by the inlet 5 of cold oil flow path groove 4, is flowed out by the outlet 6 of cold oil flow path groove 4 then, is back to the crankcase body oil sump along training wall 7 at last.
The utility model is by adding cooling machine oil guide groove 4 and training wall 7, avoided a large amount of machine oil timing chain via hole 2 of flowing through directly to wash away timing chain, bent axle, and the component that cooperate with it.Thereby effectively protect the usability of motor, prolong the working life of motor.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
