Abstract

A pivot bearing suitable for two connecting rods in at least one piston of an internal combustion engine having two crankshafts, includes radial bearing regions that are provided with bolt boreholes and are disposed on either side of a center longitudinal plane of the piston and delimit connecting rod ends, forming an intermediate space. The bearing regions are designed as cylinder bodies having a crucible-like cross-section, of which each cylinder body has a base wall and a bearing ring jacket. The base walls of the two cylinder bodies extend at a distance from each other, and the bearing ring jackets surrounding the base walls are guided away from the base walls in opposite directions. One or more connecting supports run between the base walls. The bearing ring jackets cooperate with the piston boreholes in a rotatably movable manner. The base walls are connected to bearing bushings which are oriented in the axial direction of the pivot bearing and into which the bolt boreholes are incorporated. The pivot bearing is made of a material that brings about a targeted low-weight construction of the pivot bearing, while offering high strength and low wear.
