Description
Technical field
The utility model belongs to technical field of automobile engine, particularly a kind of silumin automobile engine cylinder-body.
Background technique
According to the interrelated data introduction, the every reduction of car mass 100kg, oil consumption just can reduce about 0.7L, therefore, wants to alleviate automotive dead weight, reaches oil-saving effect, just must adopt lightweight material, so all-aluminium engine is used on a large amount of vehicles.And automobile engine cylinder-body is a part the heaviest on the motor car engine, thereby use aluminum alloy material to make the weight that engine cylinder-body just can alleviate motor, all-aluminium engine cylinder body as present French car has reached 45%, and the new V6 engine cylinder-body of Chrysler all uses aluminum alloy material.But, because the frictional force that the inner wall of cylinder of cylinder body produced in the time of will bearing pressurized gas and pistons work and because the thermal stress that high-temperature gas causes, although adopt the all-aluminium engine cylinder body, also need be at the compound cylinder sleeve of the inner wall of cylinder of cylinder body with higher-strength and fatigue strength, therefore, the connecting part of cylinder body and cylinder sleeve still belongs to two kinds of metals, cylinder body and cylinder sleeve are fitted not tight when causing high temperature owing to two kinds of expansion of metal coefficients are different, can make cylinder sleeve produce the phenomenon of distortion in the course of the work, simultaneously, also because two kinds of metal heat transfer coefficient differences, the cylinder body thermal stress is increased, the reliability of engine operation is reduced, and the cylinder body upper surface at cylinder sleeve position also is two kinds of metals, since two kinds of metal hardness differences, the difficult planeness that guarantees the cylinder body upper surface in follow-up machining.In order to be easy to processing, guarantee the planeness of cylinder body upper surface, the CN02244694.X of Chongqing Lifan Industry (Group) Co. Ltd. patent disclosure " a kind of cylinder block ", the disclosed a kind of cylinder block of this model utility, be to cover the layer of aluminum alloy in the outside of cylinder sleeve, feature is with height of cylinder head junction plane sinking, and the aluminum alloy of the same height of covering one deck, the cylinder head junction plane that makes cylinder block is a kind of metal, machining is easy, but the connecting part of its cylinder body and cylinder sleeve still belongs to two kinds of metals, belongs to the structure of composite cylinder jacket on the inner wall of cylinder of all-aluminium engine cylinder body equally.
Suzhou MingZhi Science Co., Ltd's CN200810136556.8 patent application discloses a kind of " high-silicon aluminum alloy cylinder sleeve and imbedding process thereof ", the disclosed aluminium alloy cylinder sleeve of this application for a patent for invention, the employing silumin is made, compare with adopting Cast iron liner, alleviated the weight of motor or compressor and therefore reduced automobile fuel consumption.The imbedding process of the disclosed aluminium alloy cylinder sleeve of this application for a patent for invention, by activation processing is carried out on the cylinder sleeve surface, make cylinder sleeve reach the crystal boundary combination with combining of cylinder matrix by original mechanical bond, but adopt this technology, the just cylinder sleeve of producing carries out activation processing to the cylinder sleeve surface then, and castingin is on cylinder body, complex process not only, the weight of the motor that is alleviated is also very limited.
The conjugation that belongs to two kinds of existing cylinder sleeves of metal and cylinder body for the connecting part that solves cylinder body and cylinder sleeve is low, influence the engine operation reliability problems, the no cylinder sleeve cylinder of cylinder sleeve in the cylinder has appearred omitting in prior art, " a kind of automobile air conditioner compressor " as the CN03256012.5 of Chunhui Group Co., Ltd. Zhejiang patent disclosure, the disclosed a kind of automobile air conditioner compressor of this model utility comprises body, be provided with cylinder in the body, cylinder and described body are an integral body, the material of cylinder and body is silumin, in cylinder, omitted steel bushing, because cylinder and body have all adopted the silumin material, have alleviated the weight of automobile air conditioner compressor.But, the concrete composition and the content of this model utility and unexposed described silumin, in order further to increase the surface abrasion resistance of cylinder, this model utility is pointed out to be covered with one deck high-abrasive material on the surface of cylinder, as ultra-fine composite ceramic material.
The CN03250171.4 of Chongqing Magnesium Science ﹠ Technology Co., Ltd disclosed " aluminium alloy engine cylinder body " has provided more specifically technological scheme, this aluminium alloy engine cylinder body comprises cylinder block and cylinder barrel structure, the inwall of its cylinder barrel is the composite bed structure, this composite bed is the alumina crystallites ceramic layer, and this alumina crystallites ceramic layer is that the method with differential arc oxidation is combined as a whole itself and alloy matrix aluminum securely.Said structure often is called as " ceramic cylinder ", cylinder body equally is to make with aluminum alloy, inwall at cylinder barrel is covered with one deck ceramic layer then, essence is to replace Cast iron liner or high-silicon aluminum alloy cylinder sleeve with the inner wall of cylinder that methods such as coating or meltallizing are handled the aluminum alloy material cylinder, to satisfy the requirement of cylinder light weight, high strength and good performance of heat dissipation.But adopt the method for described coating or meltallizing to handle cylinder inner wall, operation easier is bigger, and befouling environment.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art part, and providing neither needs cylinder sleeve, does not also need coating, makes that automobile engine cylinder-body is whole to be a kind of silumin automobile engine cylinder-body of commaterial.
The technological scheme that the utility model adopted is to be provided with cylinder barrel on cylinder body, and described cylinder body and cylinder barrel and inner wall of cylinder are for adopting the integrative-structure with a kind of silumin material monolithic casting, and periphery is equipped with the heat radiation wing around the described cylinder body outside.
Described cylinder barrel is the thick thin-walled cylinder barrel of 7～9mm.
Be provided with radiating groove at described cylinder barrel periphery.
The utility model compared with prior art, simple in structure, castability is good, the wear resistance height, expansion coefficient is little, cylinder body and cylinder barrel are with a kind of silumin material, neither need other insert cylinder sleeve, need not increase coating at the inwall of cylinder barrel yet, owing to adopt with a kind of silumin material monolithic and be cast into integrative-structure and the performance of the silumin that adopted, can realize the thin-walled cylinder barrel, the radiating groove slotted eye that makes the cylinder barrel periphery be provided with can be bigger, periphery is equipped with the heat radiation wing around the cylinder body outside in addition, thereby has increased heat diffusion area, has alleviated the overall weight of cylinder body, also because cylinder body and cylinder barrel are with die casting of a kind of silumin material monolithic or low-pressure die casting, saved the production and the castingin link of tratitional technology cylinder sleeve, thereby manufacturing process is simple, the relatively low and in service reliability height of manufacture cost.
