Title:
BEARING CAP OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2016/051600
Kind Code:
A1
Abstract:
A bearing cap (1) is attached to a bulkhead (22) of a cylinder block (21) composed of light metal by means of a pair of bolts (24). The bearing cap (1) has a frame (2) composed of iron-based metal and a cast light-alloy part (3). The frame (2) has a pair of pillar sections (9) through which the bolts (24) extend and a circular-arc-shaped arch section (10). At high temperature, the span of the pair of bolts (24) increases due to thermal expansion of the light-alloy material, so that the pair of pillar sections (9) expand. This causes an intermediate area of the arch section (10) to shift upward, thereby suppressing an increase in bearing clearance.
