The utility model is to realize like this, a kind of separated oil sump, described oil sump comprises enclosure body and connecting plate, described enclosure body and described connecting plate are Split type structure, described enclosure body is provided with oil storage portion, described oil storage portion is provided with the opening corresponding with it, described opening is provided with the bindiny mechanism being connected with described connecting plate, described bindiny mechanism is provided with the first bolt hole that connects described connecting plate, described connecting plate is provided with the first connecting end surface matching with described bindiny mechanism, described the first connecting end surface is provided with the second bolt hole being connected with enclosure body, described the first bolt hole and described the second bolt hole adapt, and both distributions that are all centrosymmetric, described the first connecting end surface is connected with the second connecting end surface by transition part, described the second connecting end surface is provided with the 3rd bolt hole for connecting cylinder block bottom surface, the side face area that described the 3rd bolt hole is connected to form is greater than the corresponding side face area of described the second bolt hole.
As a kind of improved plan, described bindiny mechanism comprises the junction plane extension part extending to described enclosure body one end from the position of described opening, described opening and described junction plane extension part surrounding are provided with lug boss, and the upper-end surface of described lug boss is provided with described the first bolt hole.
As a kind of improved plan, the side of described lug boss is provided with wave structure, and described wave structure and described the first bolt hole adapt.
As a kind of improved plan, described transition part top is set to wave structure near the position of described the second connecting end surface, and described wave structure and described the 3rd bolt hole adapt.
Because oil sump is set to the Split type structure being made up of enclosure body and connecting plate, on the connecting end surface of enclosure body and connecting plate, the bolt hole that is centrosymmetric and distributes is set respectively, realize the positive and negative all assembling effects of oil sump.
