Abstract
The utility model relates to a vehicle engine cylinder body with a cylinder sleeve location structure, which comprises an aluminum cylinder body. The utility model is characterized in that a cylinder sleeve is also arranged in a cylinder barrel of the aluminum cylinder body; annular grooves are distributed on the periphery of the cylinder sleeve at intervals; and annular convex stations combined corresponding to the shape and the position of the annular grooves are arranged on the inner surface of the cylinder barrel of the aluminum cylinder body. By using the utility model, the combing strength between the cylinder sleeve and the aluminum cylinder body can be effectively ensured, the effective heat transmission among metals is ensured, the cooling effect of an engine is effectively improved, the processing and assembling links are reduced, the weight of the engine is reduced, and the fuel economy of the engine is improved.
Description
Technical field
The utility model belongs to the parts of motor car engine, relates to a kind of automobile engine cylinder body that the cylinder sleeve position structure is arranged.Be applicable in the casting aluminum cylinder of motor.
Background technique
Along with national legislation to improving constantly that vehicle fuel consume limit value requires, reduce the vital task that vehicle fuel consume has become the motor industry.The mode that reduces vehicle fuel consume is a variety of, and the automobile loss of weight is exactly a ring wherein, and the motor loss of weight is the important component part of automobile loss of weight.Engine weight mainly concentrates on the big part such as cylinder body, bent axle, flywheel, cylinder cap, the ratio maximum that accounts for of cylinder body wherein, and therefore, cylinder body loss of weight potentiality are also maximum.On motorcar engine, cylinder block material has been a trend by cast iron rehandling aluminium, and purpose is exactly weight reduction, for guaranteeing cylinder body enough rigidity, intensity is arranged, and aluminium alloy cylinder has adopted squeeze casting, but the intensity of aluminium alloy cylinder is lower, working life is shorter.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned deficiency of the prior art, and a kind of simple in structure, automobile engine cylinder body that the cylinder sleeve position structure is arranged that using effect is good is provided.
Content of the present utility model is: a kind of automobile engine cylinder body that the cylinder sleeve position structure is arranged comprises: the aluminum cylinder of cylinder barrel is arranged, it is characterized in that: also be provided with cylinder sleeve (1) in the cylinder barrel (3) of described aluminum cylinder (2); Being intervally distributed with annular groove (4) on the outer circumferential face of described cylinder sleeve (1) (can be identical unanimities such as shape, the degree of depth, also can be inconsistent), be intervally distributed with the annular boss (5) of and combination corresponding on cylinder barrel (3) inner peripheral surface of described aluminum cylinder (2) with annular groove (4) shaped position.
In the content of the present utility model: the degree of depth of described annular groove (4) can be 0.8-1.2mm.
Compared with prior art, the utlity model has following characteristics and beneficial effect:
(1) adopts the utility model, shift to an earlier date the prefabricated motor thin-wall cylinder casing that has annular groove, before the aluminum cylinder squeeze casting, be fixed in the casting mould chamber, again by squeeze casting moulding, the complete automobile engine cylinder-body blank of formation.Adopt the utility model structure, can effectively guarantee the adhesive strength between cylinder sleeve and the aluminum cylinder, the cylinder sleeve string of avoiding motor car engine in use may occur is moving, guarantee effectively heat transmission between the metal, effectively improve the radiating effect of the cooling system of motor, realize reducing processing, assembling link, alleviate engine weight, improved the fuel economy of motor;
(2) simple in structure, easy to manufacture, using effect is good, and is practical.
Description of drawings
Fig. 1 is the utility model example structure schematic representation;
Fig. 2 is that the A-A among Fig. 1 analyses and observe part structure for amplifying schematic representation.
Among the figure: 1-cylinder sleeve, 2-aluminum cylinder, 3-cylinder barrel, 4-annular groove, 5-annular boss, 6-water jacket.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Embodiment 1: referring to each accompanying drawing.
A kind of automobile engine cylinder body that the cylinder sleeve position structure is arranged comprises: the aluminum cylinder 2 of cylinder barrel 3 is arranged, also be provided with cylinder sleeve 1 (material is a high strength alloy steel) in the cylinder barrel 3 of described aluminum cylinder 2; Be intervally distributed with annular groove 4 on the outer circumferential face of described cylinder sleeve 1, be intervally distributed with the annular boss 5 (annular groove 4 promptly constitutes the cylinder sleeve position structure with combining of annular boss 5) of and combination corresponding on cylinder barrel 3 inner peripheral surfaces of described aluminum cylinder 2 with annular groove 4 shaped positions.
The preparation of this embodiment's automobile engine cylinder body: before aluminum cylinder 2 die casting, make in advance earlier or processing cylinder sleeve 1, process annular groove 4 spaced apart, the about 1mm of the degree of depth of annular groove 4 on the outer circumferential face of cylinder sleeve 1; When die casting, cylinder sleeve 1 is fixed on the correct position of mould, can enter casting process, cast out automobile engine cylinder body blank with good transmission of heat and fixation structure.
The aluminum cylinder 2 that adopts this embodiment's die casting to go out, can improve the flowability of aluminum alloy around cylinder sleeve 1, do not have casting defect between cylinder sleeve 1 material and aluminum cylinder 2 materials, make between cylinder sleeve 1 and the aluminum cylinder 2 enough adhesive strengths are arranged, also guarantee the effective heat conduction efficiency between the metal, guarantee the cooling effect of engine cooling system, realized the purpose of weight reduction under the prerequisite that does not reduce engine performance;
The utility model is not limited to the foregoing description, and the utility model content is described all can implement and have described good result.
Claims (2)
1. the automobile engine cylinder body that the cylinder sleeve position structure is arranged comprises: the aluminum cylinder of cylinder barrel is arranged, it is characterized in that: also be provided with cylinder sleeve (1) in the cylinder barrel (3) of described aluminum cylinder (2); Be intervally distributed with annular groove (4) on the outer circumferential face of described cylinder sleeve (1), be intervally distributed with the annular boss (5) of and combination corresponding on cylinder barrel (3) inner peripheral surface of described aluminum cylinder (2) with annular groove (4) shaped position.
2. by the described automobile engine cylinder body that the cylinder sleeve position structure is arranged of claim 1, it is characterized in that: the degree of depth of described annular groove (4) is 0.8-1.2mm.
