Abstract
The utility model provides an improve sealing performance and increase oil pan in oil storage space adopts the whole punching press of steel sheet to form, including shallow oil bath, dark oil bath, oil drain plug screw mounting hole, last uncovered department is equipped with the last mounting flange face of being connected with upper crankcase, lies in a plurality of mounting hole peripheries and be equipped with an annular groove on last mounting flange face, and the inboard that upward lies in the annular groove on the mounting flange face is equipped with a plurality of closed recesses that are certain law and arrange, shallow oil bath bottom is equipped with the whole evagination strengthening rib of the width direction seriate of the shallow oil bath in a plurality of edges, and whole evagination strengthening rib all extends along the length direction of shallow oil bath outer wall. The utility model discloses an institutional advancement of the last mounting flange face of oil pan, it can to carry high leakproofness, be equipped with whole evagination strengthening rib at shallow oil bath, increased intensity, whole evagination strengthening rib makes the interior bottom of shallow oil bath form the recess to increase the oil storage capacity.
Description
Technical field
The utility model belongs to the crankcase of motor car engine, especially a kind ofly improves sealability and increases the oil sump of oil storage space.
Background technique
The position that automobile engine cylinder body bottom is used for installing bent axle is called crankcase, and crankcase divides upper crankcase and lower crankcase.Upper crankcase and cylinder block cast solid, lower crankcase is used for lubrication oil, and closes upper crankcase, therefore is also called oil sump.
Oil sump is in fact a upper uncovered oil vessel, and the general steel plate entirety that adopts is stamped to form, and comprises shallow oil sump and dark oil sump, is provided with purge cock mounting hole bottom dark oil sump; Upper open-mouth is provided with the upper mounting flange face be connected with upper bent axle, during installation, between the mounting flange face of upper crankcase and oil sump, Gask-O-Seal is housed, prevents oil leak.When oil sump oversize, upper mounting flange face not easily processes smooth, causes sealing bad, oil leak.For large scale oil sump, because upper mounting flange face not easily processes smooth, yield rate is caused to be 85-90%.
Summary of the invention
The utility model proposes and a kind ofly improve sealability and increase the oil sump of oil storage space, the oil tankage at shallow oil sump place can be improved, improve the bulk strength of oil sump simultaneously; Particularly by the architecture advances in the upper mounting flange face of oil sump, improve sealability.
For this reason, the technical solution of the utility model is: a kind ofly improve sealability and increase the oil sump of oil storage space, adopts steel plate entirety to be stamped to form, comprises shallow oil sump and dark oil sump, be provided with purge cock mounting hole bottom dark oil sump; Upper open-mouth is provided with the upper mounting flange face be connected with upper crankcase, upper mounting flange face is provided with multiple mounting hole, it is characterized in that: be positioned on upper mounting flange face outside multiple mounting hole and be arranged with a ring annular groove, the inner side upper mounting flange face being positioned at annular groove is provided with the closed pockets of multiple arrangement in certain rule; The degree of depth of described annular groove and closed pockets is 0.05-0.3 millimeter; Be provided with multiple overall evagination stiffening rib arranged in turn along the width direction of shallow oil sump bottom described shallow oil sump, overall evagination stiffening rib all extends along the length direction of shallow oil sump outer wall.
Further restriction to technique scheme: the degree of depth of described annular groove and closed pockets is 0.05-0.1 millimeter is optimized size.
Further restriction to technique scheme: be provided with the transition stiffening rib of overall evagination to the transition position of dark oil sump at shallow oil sump.
The beneficial effects of the utility model: owing to being provided with the closed pockets of annular groove and multiple arrangement in certain rule in upper mounting flange face, when being connected with upper crankcase by Gask-O-Seal, Gask-O-Seal squeezedly can compress into groove, ensures sealability; The particularly setting of closed pockets, when closed pockets is in when having an oil film, can causes resistance to leaking of lubricant oil further, improve sealability further; Be provided with overall evagination stiffening rib at shallow oil sump, add intensity; Overall evagination stiffening rib makes the inner bottom part of shallow oil sump form groove, thus increases oil tankage.Adopt structure of the present utility model, at machining large-sized oil sump, require suitably to relax to the smooth body in upper mounting flange face, thus make yield rate reach more than 95%.

Shown in figure: 1. shallow oil sump; 2. go up mounting flange face; 3. dark oil sump; 4. purge cock mounting hole; 5. the transition stiffening rib of overall evagination; 6. overall evagination stiffening rib; 7. mounting hole; 8. annular groove; 9. closed pockets.
Embodiment
As shown in Figure 1 and Figure 2, further describe the utility model: a kind ofly improve sealability and increase the oil sump of oil storage space, adopt steel plate entirety to be stamped to form, comprise shallow oil sump 1 and dark oil sump 3, bottom dark oil sump, be provided with purge cock mounting hole 4; Upper open-mouth is provided with the upper mounting flange face 2 be connected with upper crankcase, upper mounting flange face is provided with multiple mounting hole 7, upper mounting flange face 2 is positioned at outside multiple mounting hole and is arranged with a ring annular groove 8, the inner side upper mounting flange face being positioned at annular groove is provided with the closed pockets 9 of multiple arrangement in certain rule; The degree of depth of described annular groove 8 and closed pockets 9 is 0.05-0.3 millimeter; Be provided with multiple overall evagination stiffening rib 6 arranged in turn along the width direction of shallow oil sump bottom described shallow oil sump, overall evagination stiffening rib 6 extends along the length direction of shallow oil sump outer wall.
Optimized, the degree of depth of described annular groove 8 and closed pockets 9 is 0.05-0.1 millimeter.As shown in Figure 1, be provided with the transition stiffening rib 5 of overall evagination at shallow oil sump to the transition position of dark oil sump, can gain in strength further.
