Embodiment
Please referring to Fig. 2, this figure is the cylinder sleeve that first embodiment of the invention provides.This cylinder sleeve is applicable to single cylinder and the in-line multi-cylinder internal-combustion engine that adopts circular slider-crank mechanism.
As shown in Figure 2, this cylinder sleeve I is a thin-wall barrel, match with the long piston of circular slider-crank mechanism, the axial length of this cylinder sleeve I is obviously more much longer than the cylinder sleeve that adopts the connecting rod internal-combustion engine, and this length is enough to hold the axial motion of the whole piston of circular slider-crank mechanism.On the outer circumferential face of thin-wall barrel 1 one ends of this cylinder sleeve I, be provided with protruding circle, after cylinder sleeve I packs cylinder of internal-combustion engine into, this protruding circle will be blocked by the cylinder upper end of body, so just can be for cylinder sleeve I provide axially locating, this protruding circle is called and supports shoulder 2.This is provided with the end face that supports shoulder 2 is the top end face of cylinder sleeve, and the other end relative with it is called the bottom end face of cylinder sleeve.In the rib portion position that thin-wall barrel sidewall and the bottom end face of cylinder sleeve I join mutually, be provided with guiding chamfering 3, this guiding chamfering 3 makes this cylinder sleeve I be convenient to insert in the cylinder.This cylinder sleeve I has the through hole that the central axis of the thin-wall barrel 1 of axis and this cylinder sleeve I intersects vertically on desired location, this through hole is used to pass crankshaft pin, is called bent axle by hole 4; This bent axle forms two by hole 4 and described thin-wall barrel intersection location and cuts circle.This bent axle is decided according to body design by hole 4 particular location in the axial direction, and this position just in time is the position that needs the installation smooth block and pass for crank pin.Need cover the whole movement length of piston crown to the axial length that cuts the circle peak from the top end face.After two sections circles occupy the certain area of thin-wall barrel sidewall surfaces, on two thin-wall barrel sidewalls that cut between the circle, leave enough width, this width equals or slightly is wider than the piston guide lateral width, makes this section cylinder sleeve I join pair for the piston guide side provides friction.
Above-mentioned cylinder sleeve I can directly inject in the single-cylinder engine cylinder, relies on described support shoulder 2 that it is positioned in the cylinder, simultaneously, needs rotating sleeve I, makes described bent axle pass through hole 4 towards correct direction, to satisfy the needs of packing smooth block into and passing crank pin.For bent axle is passed through hole 4 towards correct direction, can customize special-purpose anchor clamps, in installation process, directly cylinder sleeve I is circumferentially located.In addition, also circumferential position structure can be set on cylinder sleeve I.For example, bottom at described support shoulder 2 is provided with a raised position, and corresponding groove is set in the relevant position of body, when cylinder sleeve I is installed, have only this raised position to fall into groove, the cylinder upper end that just can make the support of described cylinder sleeve I take on 2 bottoms and body is fitted fully, like this, just can realize the circumferential location to cylinder sleeve I.But, no matter adopt which kind of circumferential position structure, all need to guarantee the sealing of cylinder.
The cylinder sleeve I that the foregoing description provides can satisfy the requirement to cylinder sleeve of the single cylinder that adopts circular slider-crank mechanism and in-line multi-cylinder internal-combustion engine.But this cylinder sleeve I is not suitable for V-arrangement and arranges internal-combustion engine, and this is by the characteristics of circular slider-crank mechanism and the designing requirement decision of dwindling engine size as far as possible.The important feature of circular slider-crank mechanism is to adopt the piston with circular slider accommodation hole, passes the big portion of internal combustion (IC) engine airframe for the cylinder in the vertical direction of this plunger designs.During design V-type body, two shared entity part of adjacent cylinder have the part that intersects, this cross section is piston guide portion position, because piston guide portion is not a complete cylinder, therefore, the position that intersects of two cylinders is designed to such an extent that press close to very much, make each cylinder this crossover sites be not one complete cylindrical, as long as this crossover sites can provide enough horizontal installing spaces for adjacent smooth block.Specifically, need section circle radius sum of the wrong cylinder gap of two cylinders exactly less than two cylinders.If the cylinder sleeve that adopts first embodiment to provide, since cylinder sleeve whole axially on each cross section be complete circle, if for the volume that reduces internal-combustion engine adopts above-mentioned cylinder form than mistake cylinder spacing, then the cylinder sleeve of two adjacent cylinder is bound to interfere each other.The cylinder sleeve of another kind of form need be provided for this reason.Second embodiment of the invention promptly addresses this problem.
Please referring to Fig. 3, this figure is the cylinder sleeve II that second embodiment of the invention provides.This cylinder sleeve II makes on the cylinder sleeve I basis that first embodiment provides, and its same area adopts same numeral and title.Compare with above-mentioned cylinder sleeve I, the difference of cylinder sleeve II is that the one section sidewall is clipped, and forms to dodge breach 6; This is dodged breach 6 positions and satisfies following requirement: on the described cylinder sleeve II two cut in the circle 5 a quilt this dodge breach 6 and clip, another section circle 5 is dodged breach over against this.The described breach 6 of dodging adopts and is parallel to cylinder sleeve II axis and perpendicular to the plane of described bent axle by hole 4 axis, intercepting obtains on proper depth.This degree of depth make dodge breach 6 and cut circle 5 occupy the certain area of thin-wall barrel 1 sidewall surfaces after, cylinder sleeve II has enough width at the entity of this fragment position, this width equals or slightly is wider than the piston guide lateral width, makes this section cylinder sleeve II join pair for the piston guide side provides friction.
As can be seen from Figure 3, this dodges breach 6 is the depressions that form in the axial intermediate portion of cylinder sleeve II, does not reach the termination of cylinder sleeve.Therefore, this to dodge breach 1 be the U-shaped position that comprises two sides of first side 6-1, second side 6-3 and a base 6-2.The described position range of breach 6 on cylinder sleeve II is axial of dodging makes cylinder sleeve II be divided into three sections in the axial direction; First section be support shoulder 2 from being provided with of cylinder sleeve first end face to the plane, 6-1 place, first side of dodging breach, the length of this section cylinder sleeve II satisfies the needed length of piston crown axial motion; Second section for dodging the axial range that breach 6 is covered; The 3rd section axial range that arrives the other end of cylinder sleeve for the plane, 6-3 place, second side of dodging breach 6.Wherein the 3rd section shorter in the axial direction.
When the cylinder sleeve II that the foregoing description provides is used for the internal-combustion engine of the V-shaped layout of cylinder, the breach 6 of dodging of adjacent cylinder sleeve II is fitted with base 6-2 mutually, be equivalent to provide the breach of mutual embedding for the position that intersects of two cylinder sleeve II, the position that should fit is mutually abutted against each other the smooth block that is installed in the cylinder sleeve mutually, thereby whole circular slider-crank mechanism size is reduced.When above-mentioned two cylinder sleeve II are used, promptly obtained a cylinder sleeve group.
The cylinder sleeve that above-mentioned second embodiment provides can be realized its function in static mounting point, but in the cylinder of not considering how to pack into.In fact, because the 3rd section of described cylinder sleeve is a complete circle, after first cylinder sleeve II packs cylinder into, when being installed in cylinder sleeve II in the adjacent cylinder and need inserting cylinder, its the 3rd section can interfere with breach 6 parts of dodging of already installed cylinder sleeve II, this cylinder sleeve II can't be packed into.Above-mentioned installation question can be solved in the body design, promptly at corresponding site the constituent element of dismountable lid as body is set, and this lid is loaded onto after the back cylinder sleeve II that adorns is packed into again.The cylinder sleeve group of using above-mentioned second embodiment to provide can be provided like this.Obviously, this solution has significantly improved the design and the manufacture difficulty of cylinder body, and nonideal solution.
Third embodiment of the invention provides a kind of cylinder sleeve, and this cylinder sleeve cooperates with the cylinder sleeve II that above-mentioned second embodiment provides, and can be good at solving the interference problem in the above-mentioned installation.
Please referring to Fig. 4, the cylinder sleeve III and second embodiment that this figure provides are basic identical, but, the 3rd section of this cylinder sleeve III, promptly dodge breach second side 6-3 to not being provided with on this section of end face that supports shoulder 2, cut out the loop 7 of a separation, the split position of this loop 7 is from second side 6-2 that dodges breach 6 and the boundary line of dodging the base 6-3 of breach 6, to extend to the cylinder sleeve bottom end face to the approaching true dip direction in cylinder sleeve III medial axis.Because described loop 7 can be separated with cylinder sleeve III integral body, therefore, in the V-arrangement machine, after at first the cylinder sleeve II that above-mentioned second embodiment is provided packs a cylinder into, it is dodged breach 6 towards its adjacent cylinder.The cylinder sleeve III that the present embodiment of packing in this adjacent cylinder provides.Specifically installation process is, with the cylinder bottom appropriate location that loop 7 is at first packed into and is housed to cylinder sleeve, described appropriate location generally is the interior edge that is provided with at the cylinder bottom port, and edge is enough to settle this loop 7 in this.Then, the main body of cylinder sleeve III is inserted this cylinder, since the 3rd section of cylinder sleeve III to be higher than the part of dodging breach 6 cut, cylinder sleeve III can not interfered with the breach 6 of dodging of cylinder sleeve II for the 3rd section, this cylinder sleeve III can dodge breach 6 by it and dodge breach 6 by the cylinder sleeve II that installed smoothly, the breach of dodging of two cylinder sleeves is fitted mutually, and the spacing of two cylinder sleeves is dwindled, and helps reducing cabinet size.After cylinder sleeve III inserts cylinder, in cylinder bottom, its 3rd section with loop 7 complementations of having packed into, form complete cylinder sleeve.The marginal angle of inclination of loop 7 and cylinder III main body has leading role, makes both installations cooperate more smooth and easy.In fact, straight line also can be adopted in this separatrix, promptly directly adopts extending naturally of base 6-2, obviously can be cumbersome when installing like this, and the position that loop 7 is installed will make cylinder sleeve III main body be difficult to be lowered to cylinder bottom a little more partially.Above-mentioned installation method order also can be reversed, and the main body of cylinder III promptly at first is installed, and then described loop 7 is installed.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from basic principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
