Side has been bolted shock reducing support leg, opens up combuster on two sides of the cylinder body, and combustion chamber and
Two sides of cylinder body are at an angle, and the inner wall of the combustion chamber is socketed with cylinder sleeve, and cylinder sleeve is cast steel material,
Two sides of the cylinder body offer screw hole, and the equal annular of screw hole equidistantly distributes the surrounding outer wall in combustion chamber, institute
The inner wall for stating groove offers stomata group close to the side of combustion chamber, and stomata group includes air inlet and venthole, the gas
The bottom outer wall of cylinder ontology offers rectangular aperture, and the inner wall that is open is welded with oil sump, and the cylinder body leans on proximal cover one
The top exterior walls of side offer oil filler point.
Preferably, two sides of the cylinder body are bolted the vapour to match with cylinder body side
Cylinder pad.
Preferably, the end cap offers threaded hole far from the side outer wall of cylinder body, and six threaded holes are equidistant
From on the side outer wall for being distributed in end cap.
Preferably, the cylinder sleeve is identical with the quantity of stomata group, and stomata group and combustion chamber communicate.
Preferably, the quantity of the shock reducing support leg is two, and two shock reducing support legs are symmetrically distributed in cylinder body bottom
On outer wall.
The utility model has the following beneficial effects:
This motor cylinder block steel-casting, by opening up combustion chamber in cylinder body, wall is socketed cylinder sleeve in the combustion chamber, passes through cylinder
Set and piston contact can directly replace cylinder sleeve when there is pull-cylinder phenomena, avoid replacement cylinder body from causing to waste, and cylinder sleeve
Material be cast steel, compared to traditional cast iron and aluminum alloy material, cast steel intensity is higher, toughness preferably and plasticity is stronger.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of motor cylinder block steel-casting schematic perspective view；
Fig. 2 be the utility model proposes a kind of motor cylinder block steel-casting overlooking structure diagram.
In figure: 1 cylinder body, 2 end caps, 3 bearings, 4 head gaskets, 5 shock reducing support legs, 6 combustion chambers, 7 cylinder sleeves, 8 stomata groups, 9
