Abstract:
1. Crankshaft bearing for a reciprocating piston-type internal combustion engine having multiple cylinders arranged in a housing made of a light metal alloy, comprising bearing bores for crank pins of a crankshaft, and first and second bearing sections with first and second thrust bearings extending across a crankshaft longitudinal plane on both sides of a bearing parting plane, said second thrust bearings being part of a crankshaft bearing bridge connected to a crankcase, connecting elements operatively supporting at least a portion of adjoining bore halves of the second thrust bearings of the crankshaft bearing bridge having bearing bores, wherein the second thrust bearings of the internal combustion engine open into longitudinal walls of the crankshaft bearing bridge with local widened areas therebetween, the connecting elements are configured as separate, relatively thin and profiled element walls between the adjoining thrust bearings, and free ends of the profiled element walls are configured as oil planes for internal combustion engine connecting rods arranged to move between the thrust bearings.
