Title:
BEARING CAP AND BEARING CAP COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2012/090605
Kind Code:
A1
Abstract:
The present invention relates to a bearing cap (11) for rotatably supporting a crankshaft by being fastened to a bulkhead (2) of a cylinder block (1). A pair of protrusions (25, 26) is formed on a pair of side surfaces (33, 34) respectively, which enlarge a joint surface (12) with the bulkhead (2) in the traverse direction of the crankshaft. By providing a pair of reinforcing sections (35, 36), which protrude in the traverse direction of the crankshaft from the pair of side surfaces (33, 34) and have a smaller projection amount than the pair of the protrusions (25, 26), at a side of a top face (19) from the pair of protrusions (25, 26), it is possible to reduce a stress to be generated by the crankshaft in a junctional region of the bearing cap (11) and the bulkhead (2) during the driving of an internal combustion engine without impairing the rigidity of the bearing cap (11).
