Description
Technical field
The present invention relates to a kind of cross hair style two-stroke diesel engine that welds entablature that has, relate in particular to a kind of compactness and firm engine-mounting construction.
Background technique
The Danish Patent Application 1406/92 of publishing discloses a kind of cross hair style two-stroke diesel engine that has the entablature of welding, and described entablature is installed on the base.Entablature has the top board that has the hole, and described pore volume is received cylinder sleeve and central floor panel, and described central floor panel is divided into top cylinder frame part and bottom crankcase rack section with entablature.Two relatively vertically outer wall extend up to top board from the bottom of entablature.On two vertical offsides or the entablature and the adjacent transverse stiffener of each crosshead in vertically horizontal expansion and extend up to central floor panel between the outer wall.Four guide faces that are used for each crosshead extend up to central bottom.Four guide faces wherein two support by the transverse stiffener on the relevant first side of cross, other two guide faces are supported by the transverse stiffener of relevant crosshead opposite side.Utilize the crankcase of welding to make this engine-mounting construction be better than conventional structure, it goes up the cylinder frame that clamping has casting the crankcase of described welding.
Summary of the invention
For such background, one object of the present invention provides a kind of compactness, firm, hard and be easy to make the motor of entablature, and described motor is with reference to the motor of prior art.This purpose realizes by this motor is provided, the transverse stiffener and the guide face of described motor extend up to top board, and the guide face top of being supported by transverse stiffener on the relevant first side of cross is connected to the guide face top of being supported by transverse stiffener on the opposite side of relevant crosshead.The top of guide face is connected to each other obvious intensity and the hardness that has improved entablature.Formed thus vertical stiffener is not clear so far.And, extending up to top board by making guide face and transverse stiffener, entablature not only assembles but also firm easily.Vertically stiffener has obviously improved vertical hardness of entablature.
The top of adjacent guide face is by extending and can be connected to each other at its guide face in the plane, so that adjacent guide face can be formed by veneer.Can finish with aforesaid way for all guide faces on the crosshead same side, so that form a longitudinal extension plate structure.
Connection between adjacent guide face can be arch, to reduce notch effect.
The upper end of the longitudinal extension plate structure of the guide face of interconnection can be striden whole motor length basically and is connected on the top board.
Can be each cylinder base plate is provided, described base plate extends between guide face top.Base plate is provided with through hole and is used to hold piston rod.The chamber of Xing Chenging holds the cylinder sleeve bottom that has relief opening therefrom.
The waste gas container can be positioned at entablature.By with waste gas container and entablature integrator, the height and the width of size, the especially motor of motor are reduced significantly.And general structure will be lighter and hard.Preferably, the waste gas container is defined by the interconnection top of guide face in a side.Preferably, one of them defines the waste gas container by longitudinal side wall at opposite side.In the bottom, preferably, the waste gas container is defined by container floor, and described container floor extends between one of them at the interconnection top of guide face and the vertical outer wall of entablature.Preferably, it is low that container floor is provided with as far as possible, so that under the situation that does not increase motor height or width and obtain being used for the required volume of waste gas container.
The interconnection top that forms the guide face of a wall of waste gas container can be provided with one or several holes to each cylinder, so that waste gas combustion gas container and inlet chamber, the cylinder sleeve bottom that has relief opening is given prominence to into described indoor.
The zone of transverse stiffener can be provided with and be used for the mouth of waste gas from a cylinder to next cylinder path, and described transverse stiffener passes the waste gas container.
Camshaft can be arranged in the entablature, and transverse stiffener preferably is provided with porose and is used for the supporting element of camshaft.
Compressive force can be arranged between cylinder sleeve and the top board from the dunnage that cylinder sleeve is delivered to top board.
Another object of the present invention provides a kind of motor that has improved stretching screw configuration design, and described motor is with reference to the motor of prior art.This purpose realizes that by a kind of cross hair style two-stroke internal-combustion engine is provided described motor comprises: the base that has the main bearing that is used for camshaft; Motor/crankcase the frame of welding, it is installed on the base with top board; Two relative vertical outer walls; And transverse stiffener, it is between crosshead, in vertically horizontal expansion and extending up on the top board between the outer wall.Transverse stiffener supports the guide face that is used for crosshead.Some stretching screws are clamped together base and motor/crankcase frame, thereby stretching screw is arranged in the plane of transverse stiffener, and in the plane of transverse stiffener, being used to hold the stretching screw hollow shape by being that two branches form with the transverse stiffener bifurcated, described branch is connected to the rear side of relevant guide face.
Therefore, produced and have the entablature of stablizing the hard, compact of hollow shape and being easy to assemble, described hollow shape is used to hold stretching screw.The stretching screw number that entablature according to the present invention has is to be used for half of stretching screw required in Danish Patent Application 1406/92 disclosed entablature, thereby corresponding the saving needs to produce stretching screw, producing the hole on the top board and produce the resource of tapped hole on base.And the end that is welded to the stiffening plate on the guide face can be set up the plane of approaching transverse stiffener.The benefit of doing like this is that the stiffening plate known to the Danish Patent Application 1406/92 needs complicated welding in the bottom of the entablature that is used to cave in, and described depression is used to hold Main bearing bolt/screw.Utilize the present invention can avoid these depressions and caused thus complicated welding.
