Oilsump Assembly, Internal Combustion Engine, Vehicle, and Method

Abstract

An oil sump assembly comprises an oil reservoir with a flange. A framework interconnects the flange and the engine mounting surface, and comprises a first frame part that provides an interface between the flange and the engine mounting surface, and a second frame part that is removably fixated to the first frame part by an internal fixation arrangement. A recess is formed between the first and second frame part. The flange extends into the recess and is sandwiched between sidewalls of the recess by a first gasket that covers the first and second side of the flange. The flange and the first gasket are clamped onto each other by the internal fixation arrangement between the first and second frame part. A second gasket is arranged for sealing a connection between the first frame part and the engine mounting surface.

1 . An oil sump assembly that is connectable to an internal combustion engine, wherein the oil sump assembly comprises an oil reservoir with an opening for collecting oil from the internal combustion engine, wherein the oil reservoir comprises a flange that extends around the opening and that is arranged for circumferentially mounting the oil reservoir to an engine mounting surface, wherein the oil sump assembly comprises a framework arranged for interconnecting the flange and the engine mounting surface, wherein the framework comprises:
 a first frame part that circumferentially extends around the opening on a first side of the flange, wherein the first frame part provides an interface between the flange and the engine mounting surface;   a second frame part that is provided on a second side of the flange opposite the first side, wherein the second frame part is removably fixated to the first frame part by an internal fixation arrangement;   wherein a recess is formed between the first frame part and the second frame part;   wherein the flange extends into the recess and is sandwiched between sidewalls of the recess by a first gasket that covers the first side and the second side of the flange;   wherein the flange and the first gasket are clamped onto each other by the internal fixation arrangement between the first and second frame part; and   wherein the oil sump assembly further comprises a second gasket that is arranged for sealing a connection between the first frame part and the engine mounting surface.   
     
     
         2 . The oil sump assembly according to  claim 1 , wherein the flange is undersized with respect to the engine mounting surface,
 wherein the first frame part radially extends beyond an outer contour of the flange for conforming to the engine mounting surface, and   wherein the second frame part is removably fixated to a portion of the first frame part beyond the outer contour of the flange.   
     
     
         3 . The oil sump assembly according to  claim 1 , wherein the framework comprises an internal alignment arrangement for aligning the first frame part and the second frame part with respect to each other. 
     
     
         4 . The oil sump assembly according to  claim 1 , wherein the framework comprises an external alignment arrangement for aligning the first frame part and the engine mounting surface with respect to each other. 
     
     
         5 . The oil sump assembly according to  claim 1 , wherein the framework comprises an external fixation arrangement for fixating the first frame part to the engine mounting surface. 
     
     
         6 . The oil sump assembly according to  claim 1 , wherein at least one sidewall of the sidewalls of the recess is formed by the first frame part. 
     
     
         7 . The oil sump assembly according to  claim 1 , wherein at least one sidewall of the sidewalls of the recess forms a seating surface for positioning the first gasket in the recess. 
     
     
         8 . The oil sump assembly according to  claim 7 , wherein the first gasket comprises a sealing lip arranged for engaging with the seating surface. 
     
     
         9 . The oil sump assembly according to  claim 1 , wherein the first gasket comprises a skirt that extends between the second frame part and a sidewall of the oil reservoir. 
     
     
         10 . The oil sump assembly according to  claim 1 , wherein, when mounted to the engine mounting surface, a channel is formed between the first frame part and the engine mounting surface,
 wherein the channel is arranged for aligning and securing the second gasket.   
     
     
         11 . An internal combustion engine, comprising the oil sump assembly according to  claim 1 . 
     
     
         12 . A vehicle, comprising the internal combustion engine according to  claim 11 . 
     
     
         13 . A method for assembling the oil sump assembly according to  claim 1 , wherein the method comprises:
 mounting the first gasket to the flange such that the first gasket covers the first side and the second side of the flange;   positioning the first frame part of the framework onto the first side of the flange, with the first gasket therebetween;   positioning the second frame part onto the second side of the flange, with the first gasket therebetween, such that the flange is sandwiched between sidewalls of the recess by the first gasket covering the first and second side;   clamping the first gasket and the flange onto each other by fixating an internal fixation arrangement between the second frame part and the first frame part.   
     
     
         14 . The method according to  claim 13 , further comprising
 connecting the oil sump assembly to an internal combustion engine by fixating the first frame part to the engine mounting surface with a second gasket therebetween.
