Also will be described in more detail the utility model with reference to accompanying drawing based on embodiment hereinafter.In the drawings:
Fig. 1 is the plan view of the cylinder cover structure for motor of embodiment of the present utility model.
Fig. 2 is the internal view (A-A section) of Fig. 1.
In the accompanying drawings, identical parts use identical reference character.Accompanying drawing is not according to the scaling of reality.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1 and Fig. 2, it is respectively the internal view of the plan view of the cylinder cover structure for motor of embodiment of the present utility model and the cylinder cover structure for motor of embodiment of the present utility model.
As depicted in figs. 1 and 2, in the embodiment of the application, this cylinder cover structure comprises upper cylinder cover assembly 1, lower cylinder cover component 2 and baffle assembly 3.Wherein, the upper wall of this baffle assembly 3 is connected with the diapire of upper cylinder cover assembly 1, and the lower wall of this baffle assembly 3 is connected with the upper wall of lower cylinder cover component 2.Particularly, this baffle assembly 3 can adopt casting technique to complete manufacture, and is connected as a whole with upper cylinder cover assembly 1 and lower cylinder cover component 2 respectively.Like this, the baffle assembly 3 adopting casting technique to make has that structural strength is high, not fragile, any surface finish and the high advantage of precision.
As depicted in figs. 1 and 2, in the utility model, for ensureing structural strength and the rigidity of this baffle assembly 3, avoid when being subject to foreign impacts power and be damaged, therefore this baffle assembly 3 can be formed by aluminum alloy material manufacture.
In addition, because aluminum alloy material has quality gently, even if be arranged in cylinder cover structure by this baffle assembly 3, the weight of this cylinder cover structure can not also significantly be increased.Like this, just can reduce the fuel consumption of motor widely, save financial cost.
As depicted in figs. 1 and 2, in the embodiment of the application, the zone line 31 of this baffle assembly 3 offers multiple mounting hole 311, and this mounting hole 311 is for installing patch (not shown).Particularly, this each mounting hole 311 is arranged in compartment each other with each upper oil sump hole 11 as described below.Like this, the setting of this mounting hole 311, just can play and strengthen the effect of this cylinder cover structure rigidity, thus reduces the probability that cylinder cover structure is damaged, and extends the working life of cylinder cover structure.
In addition, by installing patch in mounting hole 311, thus can realize preventing the water that is positioned at above cylinder cover structure and the object of oil mixing be positioned at below cylinder cover structure.
In the embodiment of the application, due to the setting of baffle assembly 3, cylinder cover structure is divided into upper and lower two oil sumps, is namely respectively oil sump 4 and lower oil sump 5.Meanwhile, the setting of this baffle assembly 3, can be isolated in the valve assembly (not shown) in cylinder cover structure in lower oil sump 5.Like this, just greatly reduce the operational sound of valve assembly, thus decrease noise.
As shown in Figure 1, in a preferred embodiment, the surrounding of this baffle assembly 3 offers bolt hole 32.The setting of this bolt hole 32, for matching with bolt, thus completes this triangular installation of upper cylinder cover assembly 1, lower cylinder cover component 2 and baffle assembly 3 and fixes.Fastening by bolt, just can reduce rocking of this baffle assembly 3, thus can reduce the vibration of baffle assembly 3, further, decrease noise.
In a preferred embodiment, the arranged on left and right sides of this baffle assembly 3 offers tappet bore 33 respectively.The setting of this tappet bore 33, for providing the space of laying tappet (not shown), thus makes tappet drive the opening and closing of valve assembly, thus realizes the air inlet of firing chamber and the function of exhaust.
In a preferred embodiment, the thickness range of this baffle assembly 3 is for being more than or equal to 3.5 millimeters and being less than or equal to 5 millimeters.Like this, just can facilitate the casting of this baffle assembly 3, reduce technology difficulty and save financial cost.In addition, the thickness of this baffle assembly 3 is arranged in above-mentioned scope, just effectively can completely cuts off the noise that valve assembly operationally produces.
If the thickness range of this baffle assembly 3 is for being less than 3.5 millimeters, then the thickness due to this baffle assembly 3 is too thin, substantially increases technology difficulty and is unfavorable for manufacturing.In addition, due to the thinner thickness of this baffle assembly 3, then make the strength and stiffness of this baffle assembly 3 to ensure, thus can exist and hold flimsy drawback.
If the thickness range of this baffle assembly 3 is greater than 5 millimeters, then not only wastes raw material and waste financial cost, meanwhile, too increase the weight of cylinder cover structure, thus increase oil consumption.Therefore the thickness range of this baffle assembly 3 is for being more than or equal to 3.5 millimeters and being less than or equal to 5 millimeters.
In a preferred embodiment, this upper cylinder cover assembly 1 offers the upper oil sump hole 11 arranged in compartment with each mounting hole 311 respectively.
