Embodiment
The embodiment of the utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning
Same or similar element is represented to same or similar label eventually or there is same or like element.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and cannot be construed to the utility model
Limitation.
The embodiment of the utility model：As Figure 2-3, a kind of motor cylinder protective shield oil baffle, including main oil baffle
1, specifically, main 1 friction welding (FW) of oil baffle is in the cylinder cap shield 8 of engine.Inlet port is offered respectively on the main oil baffle 1
2nd, oil return opening 3 and machine oil import 4；Inlet port 2 is for the inside of cylinder cap shield 8 and the external world together with the surface of the inlet port 2
Equipped with the first auxiliary oil baffle 5, the first auxiliary oil baffle 5 is fixed on the main oil baffle 1；As shown in figure 4, the machine oil into
Mouth 4 is usually located at the underface of the oil filler 81 of cylinder cap shield 8, and the second auxiliary gear oil is equipped with the top of the machine oil import 4
Plate 6, the second auxiliary oil baffle 6 are fixed on the main oil baffle 1, and are partially overlapped with the main oil baffle 1.
Motor cylinder protective shield oil baffle provided by the utility model, by being arranged above second in machine oil import 4
Auxiliary oil baffle 6, and make the second auxiliary oil baffle 6 and main oil baffle 1 there is part to coincide with the upper and lower, i.e., adopted in the lower section of oil filler 81
With double layer design, spatial offset is realized in vertical direction, and the oil mixing with water gas below main oil baffle 1 can be prevented to rise,
Avoid it from assembling at cap 82, efficiently solve the problem of lubricating oil emulsion even freezes under low temperature environment；This reality
The first auxiliary oil baffle 5 is additionally provided with the surface of inlet port 2 with new, the rate of climb of oil gas can be effectively reduced, contributed to
Oil-gas Separation.
It is preferably carried out in one kind in mode, the difference in height between the second auxiliary oil baffle 6 and the main oil baffle 1 is
10mm-15mm, the length of intersection is 20mm-40mm.The effect of second auxiliary oil baffle 6 is to stop that following oil gas rises,
But the filling of machine oil cannot be hindered, and the length of the difference in height and intersection between the second auxiliary oil baffle 6 and main oil baffle 1
Degree, it will the rising of oil gas and the filling of machine oil are directly affected, when difference in height is excessive, the length of intersection is smaller, although
Filling is smooth, but stops the less effective of oil gas；When difference in height is too small, the length of intersection it is longer when, although stop
The effect of oil gas is fine, but can influence to fill speed to a certain extent.Preferably, therefore the second auxiliary oil baffle 6 and main gear
Difference in height between oiled-plate method 1 is 10mm-15mm, the length of intersection is 20mm-40mm, can both be stopped on following oil gas
Rise, and the filling of machine oil will not be hindered.
Further, the difference in height between the described second auxiliary oil baffle 6 and the main oil baffle 1 is 13mm, intersection
Length be 32mm.It was verified that the difference in height between the second auxiliary oil baffle 6 and main oil baffle 1 is 13mm, intersection
When length is 32mm, stop oil gas rise with machine oil filling resultant effect it is optimal, so, it is highly preferred that two auxiliary oil baffles 6 and
Difference in height between main oil baffle 1 is 13mm, the length of intersection is 32mm.
It is preferably carried out in another kind in mode, as shown in Fig. 2, oil leak hole 7 is additionally provided with the main oil baffle 1, it is described
Oil leak hole 7 is between the oil return opening 3 and the machine oil import 4, specifically, near the root of Oil-gas Separation component
(not shown in Oil-gas Separation component drawings).Since the engine oil flow of turning everywhere is not smooth, in order to release corner cannot voluntarily under
The machine oil of stream, oil leak hole 7 is set between oil return opening 3 and machine oil import 4 close to edge.
Further, a diameter of 3mm of the oil leak hole 7, aperture is excessive, then following oil gas can rise out of hole, increases
The burden of Oil-gas Separation component is added；Aperture is too small, then does not reach the purpose of draining.It is preferred, therefore, that oil leak hole 7 is a diameter of
3mm, can achieve the purpose that draining, will not how much oil gas rise out of hole.
In a kind of specifically embodiment, the oil return opening 3 is in flat, width 1mm, length 8mm.Oil return opening
3 machine oil for mainly allowing Oil-gas Separation components apart to go out are back in oil sump.The hole of flat is more advantageous to the flowing of fluid,
And since the oil mass of reflux is not very big, bore is excessive, and liquid cannot fill whole oil return opening 3, then have oil mixing with water gas
Rise from there, increase the burden of Oil-gas Separation component, according to actual use, width 1mm, length 8mm, best results.
The structure, feature and effect of the utility model are described in detail based on the embodiments shown in the drawings, with
Upper described is only the preferred embodiment of the utility model, but the utility model is to limit practical range shown in drawing, it is every according to
The change that conception according to the utility model is made, or the equivalent embodiment of equivalent variations is revised as, still without departing from specification and figure
When showing covered spirit, it should be within the protection scope of the present utility model.
