Pivot bearing for two connecting rods

A pivot bearing for two connecting rods in at least one piston of an internal combustion engine equipped with two crankshafts driven via the piston and the two connecting rods, the pivot bearing being accommodateable in piston bore holes of the piston, the pivot bearing comprising:

• radial bearing regions that are provided with bolt bore holes and that are disposed on either side of a center longitudinal axis of the piston, the radial bearing regions delimiting the connecting rod ends and forming an intermediate space, and the bolt bores holes being configured to mount connecting rod bolts for ends of the two connecting rods, wherein
• the radial bearing regions are configured as cylinder bodies having a crucible-shaped cross-section on a side of each cylinder body that face away from a center of the pivot bearing,
• each cylinder body has a base wall and a bearing ring jacket, with a portion of each bearing ring jacket forming a cylindrical side wall portion of the crucible-shaped cross-section,
• 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 extend between the base walls,
• the bearing ring jackets cooperate with the piston bore holes in a rotatably movable manner,
• the base walls are connected to bearing bushings which are oriented in an axial direction of the pivot bearing into which the bolt bore holes are incorporated, the bearing bushings extending axially away from the center of the pivot bearing into the crucible-shaped cross-section, and
• the pivot bearing is made of a material that provides a low-weight construction.
