Built-cylinder crankcase, in particular for an internal combustion engine of a motor vehicle, and method for producing such a built-cylinder crankcase

摘要

The invention relates to a cylinder crankcase (10) for an internal combustion engine of a motor vehicle, comprising a base body (12) made of cast aluminum alloy, which has at least one cylinder wall (16) bounding a cylinder (14) of the cylinder crankcase (10) and at least one cylinder wall (16) in the radial direction of the cylinder (14) outwardly at least partially covering outer wall (18), wherein the cylinder crankcase (10) at least one separately from the base body (12) formed and between the cylinder wall (16) and the outer wall (18 ) arranged stiffening element (24) which is joined after the casting of the base body (12) between the cylinder wall (16) and the outer wall (18).
