Abstract
The utility model discloses an oil pocket draining structure of a cylinder cap. The oil pocket draining structure comprises a cylinder cap, of which the upper portion is provided with an inlet cylinder cap bolt hole and an exhaust cylinder cap bolt hole. An oil pocket is arranged on the upper portion of the cylinder cap, and the side of the inlet cylinder cap bolt hole and the exhaust cylinder cap bolt hole of the cylinder cap is provided a draining hole. The oil pocket penetrating through the bottom of the cylinder cap is connected to the draining hole, and the draining hole is provided with a boss for avoiding an exhausting manifold fixing bolt hole. The boss is laterally arranged in the draining hole. Such a structure ensures fully draining, and reduces the weight of the cylinder cap, and the profile of the cylinder cap is compact.
Description
Technical field
The utility model relates to part of automobile engine field, is specifically related to a kind of cylinder head oil pocket oil drainage structure.
Background technique
Engine cylinder cover draining hole is in order to release in time the lubricant oil in engine cylinder cover oil pocket, guarantee that motor normally moves, at present, the draining hole of motor is generally arranged in the intake and exhaust side of cylinder cap, dodge water jacket, air flue, cylinder bolt hole, spring for valve seat surface, intake and exhaust manifold bolt etc., by machine, add the effect that 2～3 spill ports reach oil return, general difficult arrangement, cannot effectively reach oil return object, so, generally can take to increase cylinder cap width, to reach, increase spill port area, so just strengthened motor boundary dimension, make engine structure not compact.Along with the development of automotive industry, Consumer is more and more higher to the lightweight requirements of motor, makes engine structure compacter, and weight is lighter, is a difficult problem that needs breakthrough in prior art.
Summary of the invention
The utility model is exactly in order to overcome above-mentioned deficiency, provides a kind of compact structure, lightweight cylinder head oil pocket oil drainage structure, to meet the light-weighted demand of motor.
The cylinder head oil pocket oil drainage structure that the utility model is designed, comprise cylinder head, described cylinder head top is provided with air inlet cylinder bolt hole and exhaust cylinder bolt hole, described cylinder head top is provided with oil pocket, it is characterized in that: the air inlet cylinder bolt hole of described cylinder head and exhaust cylinder bolt hole one side are provided with draining hole, on described draining hole, connect oil pocket and be through to cylinder head bottom, be provided with the boss of dodging intake and exhaust manifold fixed bolt hole in draining hole, described boss is horizontally set in draining hole.
Further, described draining vestibule body is up-small and down-big structure.
Further, each air inlet cylinder bolt hole one side of described air inlet side is provided with air inlet side draining hole, and the 3rd exhaust cylinder bolt hole one side of described exhaust side is provided with exhaust side draining hole.
Again further, described air inlet cylinder bolt hole outside is provided with stiffening rib, and described stiffening rib extends in draining hole, in order to increase the intensity of cylinder bolt hole.
Again further, described draining vestibule span cylinder bolt hole minimum range is 10 ± 1mm.
Again further, described draining vestibule span cylinder cap outer surface minimum wall thickness (MINI W.) is 4mm.
The utility model has the advantage of: in the setting of cylinder head intake and exhaust side cylinder bolt hole side, have again draining hole, and boss is set in draining hole dodges intake and exhaust manifold bolt hole, design stiffening rib increases cylinder head bolt hole strength simultaneously; In the situation that guaranteeing former cylinder cap size constancy, by casting draining hole, make full use of the space between intake and exhaust manifold fixed bolt hole and cylinder head bolt hole like this, not only reach the effect of abundant oil return, and cylinder cap weight saving, compact appearance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model cylinder head oil pocket oil drainage structure.
Fig. 2 is the backsight structural representation of Fig. 1.
Fig. 3 is A-A sectional structure schematic diagram in Fig. 2.
Fig. 4 is for manufacturing cylinder cap draining hole oil pocket sand core structure schematic diagram used.
In figure: cylinder head 1, oil pocket 2, air inlet cylinder bolt hole 3, exhaust cylinder bolt hole 5, air inlet side draining hole 4, exhaust side draining hole 6, oil pocket core 7, pit 8, boss 9, stiffening rib pit 10, stiffening rib 11.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
Cylinder head oil pocket oil drainage structure shown in figure, comprise cylinder head 1, described cylinder head 1 top is provided with air inlet cylinder bolt hole 3 and exhaust cylinder bolt hole 5, described cylinder head 1 top is provided with oil pocket 2, concrete space below cylinder head 1 exterior edge face, top plane is as shown in FIG. oil pocket 2, the air inlet cylinder bolt hole 3 of described cylinder head 1 and exhaust cylinder bolt hole 5 one sides are provided with draining hole, on draining hole, connect oil pocket 2 and be through to cylinder head 1 bottom, the motor that leans forward and arrange towards air inlet side for motor, add the impact that is subject to cylinder head 1 space, preferably in each air inlet cylinder bolt hole 3 one side of air inlet side, be provided with the air inlet side draining hole 5 of up-small and down-big structure, in the 3rd exhaust cylinder bolt hole 5 one sides of exhaust side, be provided with the exhaust side draining hole 6 of up-small and down-big structure, on draining hole, connect oil pocket 2 and be down through to cylinder head 1 bottom, in draining hole, be horizontally arranged with the boss 9 of dodging intake and exhaust manifold fixed bolt hole.In order to increase the intensity of cylinder bolt hole, at intake and exhaust side air inlet cylinder bolt hole 3 and exhaust cylinder bolt hole 5 arranged outside, there is the stiffening rib 11 that extends to draining hole.
As Fig. 1, the motor that leans forward and arrange towards air inlet side for motor, at cylinder head 1 each air inlet side cylinder bolt hole 3 place, be provided with air inlet side draining hole 4 and connect oil pocket 2, at exhaust side the 3rd exhaust cylinder bolt hole 5 places, be provided with exhaust side draining hole 6 and connect oil pocket 2 simultaneously, machine oil in cylinder head 1 can be by 5 air inlet side draining hole 4 drainings of air inlet side, in automobile climbing process, can pass through exhaust side draining hole 6 drainings of exhaust side simultaneously.
As Fig. 2,3,4, in oil pocket core 7 design processes, design pit 8, forms the metal convex 9 of dodging intake and exhaust manifold bolt hole after cylinder cap casting, guarantee that the machine of intake and exhaust manifold bolt hole adds wall thickness; Design stiffening rib groove 10 simultaneously, after cylinder cap casting, form stiffening rib 11, strengthen cylinder bolt hole strength and cylinder cap bulk strength; Shown in Fig. 4, root guarantees that draining wall surface of the hole is 10 ± 1mm apart from cylinder head bolt pitch-row from a, guarantees that draining wall surface of the hole is 4mm apart from cylinder cap outer surface minimum wall thickness (MINI W.) b.
Like this, just take full advantage of cylinder cap outer surface apart from the space length between cylinder bolt hole, by the casting in draining hole, dodge intake and exhaust manifold bolt hole, not only reach the object of abundant draining, alleviate cylinder cap weight, cylinder cap compact appearance simultaneously.
