Description
Technical field
The utility model relates to a kind of cover assembly of cylinder head.
Background technique
The material that the valve mechanism cover of current use is used is metallic aluminium, and thickness is thicker, and weight is relatively heavier, and toughness is less better, in engine operation process, affected by vibration, and the risk of inefficacy is relatively large.Simultaneously due to aluminum casting, amount of finish is comparatively large, and processing charges is high.Secondly when motor runs, valve and rocking arm can send the noise of rule, and shield this noise mainly by the buffer action of valve mechanism cover.But existing scheme adopts metal material, and noise transfer rate is high, the weak effect of vibration insulation and noise reduction.
Separately, valve mechanism cover needs install as added the component such as machine oil lid, deaerator and valve mechanism cover pad, cause installation workload large during use, assembling is wasted time and energy.
Model utility content
Technical problem to be solved in the utility model is: provide a kind of cover assembly of cylinder head, the technical problem that existing valve mechanism cover user cost is high to solve, vibration insulation and noise reduction weak effect and installation are wasted time and energy.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of cover assembly of cylinder head, comprise the cylinder head cover body be made up of plastic material, the upper surface of described cylinder head cover body is provided with filler cap, the sidewall of described cylinder head cover body is provided with deaerator, the inside of described cylinder head cover body is fixed with oil gas pre-separation assembly, and described filler cap, described deaerator and described oil gas pre-separation assembly and described cylinder head cover body become one;
Form an airtight cavity between described oil gas pre-separation assembly and the inwall of described cylinder head cover body, described airtight cavity is communicated with the intake duct of described deaerator.
As improving further, described oil gas pre-separation assembly fixes on the inside of described cylinder head cover body by plastic friction solid welding.
As improving further, the top of described cylinder head cover body is also integrated with nameplate.
Have employed technique scheme, the beneficial effects of the utility model are:
Become one due to machine oil lid, deaerator, oil gas pre-separation assembly and cylinder head cover body will be added, component combination independent of each other is become an entirety, simplify installation steps, decrease the connecting pipeline between each parts, simultaneously because level of integration is high, cost reduces greatly, and the appearance quality of motor have also been obtained raising; Separately the material of valve mechanism cover is replaced with plastic material by metal material, overall processing and user cost reduce greatly; Owing to being integrated with oil gas pre-separation assembly in cylinder head cover body, and oil gas oil separation assembly is communicated with the intake duct of the deaerator of external harmoniousness with the airtight cavity formed between cylinder head cover body inwall, by both actings in conjunction, greatly improve the efficiency of Oil-gas Separation, wherein the separation effect of oil gas pre-separation assembly can reach more than 85%, therefore also substantially increases the life-span of deaerator simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the worm's eye view of Fig. 1;
Fig. 3 is the structural representation of Oil-gas Separation assembly in Fig. 1;
In figure: 1, cylinder head cover body, 2, filler cap, 3, deaerator, 4, oil gas pre-separation assembly, 40, vent, 5, packing ring, 6, nameplate.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in fig. 1, a kind of cover assembly of cylinder head, comprise the cylinder head cover body 1 be made up of plastic material, because metal material is relative to plastics, its chemical stability is less better, is easily subject to the impact of the acid-base solution in environment, and its thermal distortion is also higher than plastics, so on environmental suitability, aluminum valve mechanism cover is not as plastic material.
Filler cap 2 is provided with at the upper surface of the cylinder head cover body 1 of plastic material, on the sidewall of cylinder head cover body 1, be provided with deaerator 3 simultaneously, and be fixed with oil gas pre-separation assembly 4 in the inside of cylinder head cover body 1, and filler cap 2, deaerator 3 and oil gas pre-separation assembly 4 and cylinder head cover body 1 become one.Valve mechanism cover after integrated, functionally with traditional metal cylinder housing and indistinction.
Above-mentioned component combination independent of each other is become an entirety, simplify the installation steps of valve mechanism cover and oil-gas separation mechanism, decrease the connecting pipeline between each parts, both the installation of cover assembly of cylinder head had been conducive to, simultaneously because level of integration is high, cost reduces greatly, and the appearance quality of motor have also been obtained raising.
High integrated valve mechanism cover can be directly installed in cylinder head, as follows:
Integrated valve mechanism cover is bolted in cylinder head by 15, centre valve mechanism cover packing ring 5 seals, after installing valve mechanism cover, cap 2, deaerator 3, oil gas pre-separation assembly 4 also complete installation indirectly with signboard 6, enormously simplify installation steps, as shown in Figure 2, oil gas pre-separation assembly 4 fixes on the inside of cylinder head cover body 1 by plastic friction solid welding.
Form an airtight cavity between oil gas pre-separation assembly 4 and the inwall of cylinder head cover body 1, airtight cavity is communicated with the intake duct of deaerator 3 simultaneously.
The working principle of oil-gas separation mechanism is as follows: wherein the concrete structure of oil gas pre-separation assembly 4 as shown in Figure 3, be communicated with crankcase by 4 vents 40 of oil gas pre-separation assembly 4, after the gas of crankcase enters oil gas pre-separation assembly 4 from vent 40, the air flue muscle of oil-containing gases and valve mechanism cover inside collides, oil in gas sinks to concentrating under the effect of gravity and collision, be back to crankcase by the spill port of pre-separating mechanism, all the other oil-containing gases carry out essence filter by entering deaerator 3 after oil gas pre-separation assembly 4.
Integrated cylinder cover lid have employed rubber gasket, and compared to existing paper spacer, sealing effect improves greatly, decreases the generation of the faults such as leakage of oil.In valve mechanism cover, be integrated with signboard simultaneously, reserved space to brand-name enterprise and sign, accomplished the differentiation process of same component, saved great amount of cost.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
