Abstract
The utility model provides a wet cylinder sleeve convenient to assemble and disassemble. The wet cylinder sleeve comprises a cylinder sleeve body. The upper portion, the middle and the lower portion of the cylinder sleeve body are provided with an upper belt, a middle belt and a lower belt. A sealing groove is formed in the middle belt. A sealing ring is arranged inside the sealing groove. The outer diameter of the middle belt is larger than that of the lower belt. The outer diameter of the upper belt is larger than that of the middle belt. The upper end of the upper belt is provided with an annular boss protruding outwards. The lower end of the lower belt is provided with a guiding portion enabling the lower end of the cylinder sleeve body to be conveniently inserted into an air cylinder, and the size of the guiding portion is gradually reduced in the outer-end direction. The wet cylinder sleeve convenient to assemble and disassemble is used in cooperation with the air cylinder, and the size of the outer end of the guiding portion is smaller, so that the cylinder sleeve body is easily inserted into an inner hole of the air cylinder; the outer diameters of the lower belt, the middle belt and the upper belt are gradually expanded, and the lower belt, the middle belt and the upper belt are guided and positioned mutually, so that the cylinder sleeve body and the air cylinder are easily positioned, and assembling and disassembling are quite convenient.
Description
Technical field
The utility model relates to the cylinder sleeve in a kind of motor car engine, more particularly relates to a kind of wet cylinder liner of being convenient to installing/dismounting.
Background technique
In the automotive industry of China, motor car engine mostly is internal-combustion engine, internal-combustion engine is most important constituent element in each constituent elements of automobile, and cylinder sleeve is the heart part of internal-combustion engine, its performance is directly connected to the performance index of car load, therefore for many years the developmental research of cylinder sleeve is listed in always one of important topic in automotive industry, countless scientific research institutions have been attracted, universities and colleges, many experts such as enterprise, in scholar's input research, developed one and another Novel cylinder jacket, and be successfully applied, for technological gap has been filled up by country, also reduced to a certain extent import.
Air cylinder structure form has three kinds: without cylinder shell type, dry gas cylinder sleeve type, moisture cylinder sleeve type.Wet cylinder liner outer wall directly contacts with cooling liquid, water channel is communicated with cylinder large size, by cylinder sleeve, isolate cooling water and cylinder operation chamber completely, wall thickness 5-8mm, utilization is located up and down endless belt and is realized radial location, and axially locating coordinates realization by cylinder liner upper flange with the corresponding supporting surface in body top.
For wet cylinder liner, because the connection of cylinder sleeve and cylinder is very tight, be all interference fit conventionally, therefore cylinder sleeve is suppressed in the installation process of inlet casing, cylinder sleeve is not easy to be right against the endoporus of upper cylinder at first, to installation, has brought larger difficulty, otherwise, as the same when dismounting.
Model utility content
The purpose of this utility model is to provide a kind of wet cylinder liner of being convenient to installing/dismounting, to overcome the comparatively difficult defect of cylinder sleeve body installing/dismounting of prior art.
The purpose of this utility model realizes by the following technical solutions:
Be convenient to a wet cylinder liner for installing/dismounting, comprise cylinder sleeve body, the upper, middle and lower of described cylinder sleeve body arranges waistband, middle waistband and lower waistband, on described middle waistband, is provided with seal groove, is provided with seal ring in seal groove; Between described upper waistband and middle waistband, between middle waistband and lower waistband, form the tank of crossing by cooling water; The external diameter of described middle waistband is greater than the external diameter of lower waistband, and the external diameter of described upper waistband is greater than the external diameter of middle waistband; The upper end of described upper waistband has laterally the annular boss protruding, the lower end of described lower waistband be provided with facilitate cylinder sleeve body lower end insert in cylinder, the size diminishing guide portion of direction outward.
As the improvement to technique scheme, the external diameter of described middle waistband and lower waistband, upper waistband and middle waistband is poor is 0.05 ㎜～0.10 ㎜.
As the improvement to technique scheme, described annular boss and guide portion are all integral structure with cylinder sleeve body.
Compared with prior art, the utility model has the advantage of: the lower end of wet cylinder liner body be provided with facilitate cylinder sleeve body lower end insert in cylinder, the size diminishing guide portion of direction outward, during installation, its lower end is than the endoporus that is easier to aim at cylinder, be convenient to the installation of cylinder sleeve, cylinder sleeve body arranges waistband, middle waistband, lower waistband from top to bottom, external diameter expands from down to up gradually, during installation, three parts lead each other, the installation of very convenient cylinder sleeve body, otherwise, as the same during dismounting.
Accompanying drawing explanation
Fig. 1 is the structural representation of being convenient to the wet cylinder liner of installing/dismounting of the present utility model.
Description of symbols: 1-cylinder sleeve body; 2-cylinder; 3-seal ring; 4-crosses tank; 5-guide portion; 6-annular boss; The upper waistband of 11-; Waistband in 12-; Waistband under 13-.
Embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below, but the utility model is not limited to this.
Embodiment one:
As shown in Figure 1, the wet cylinder liner of being convenient to installing/dismounting of the present utility model, comprise cylinder sleeve body 1, cylinder sleeve body 1 is socketed in cylinder 2, the upper, middle and lower of described cylinder sleeve body 1 arranges waistband 11, middle waistband 12 and lower waistband 13, on described middle waistband 12, be provided with seal groove, in seal groove, be provided with seal ring 3; Between described upper waistband 11 and middle waistband 12, between middle waistband 12 and lower waistband 13, form and cross tank 4 by cooling water; The external diameter of described middle waistband 12 is greater than the external diameter of lower waistband 13, and the external diameter of described upper waistband 11 is greater than the external diameter of middle waistband 12; The upper end of described upper waistband 11 has laterally the annular boss 6 protruding, the lower end of described lower waistband 13 be provided with facilitate cylinder sleeve body 1 lower end insert in cylinder 2, the size diminishing guide portion 5 of direction outward.
The external diameter of described middle waistband 12 and lower waistband 13, upper waistband 11 and middle waistband 12 is poor is 0.05 ㎜～0.10 ㎜.
Described annular boss 6, guide portion 5 are all integral structure with cylinder sleeve body 1.
Cylinder sleeve body 1 supports the use with cylinder 2, the size of guide portion 5 outer ends is less, cylinder sleeve body 1 is easily inserted in cylinder 2 endoporus, lower waistband 13, middle waistband 12, upper waistband 11 external diameters expand gradually, lead each other, location, makes cylinder sleeve body 1 easy with cylinder 2 location each other, and installing/dismounting is very convenient.
