ABSTRACT:
The invention relates to a crankshaft drive for an internal-combustion engine of V-type having a crankshaft with two mutually offset crank pins per throw, the pins being inter-connected via a narrow intermediate element. In order to ensure an optimum axial guidance of two connecting rods mounted rotatably on the crank pins, even without an intermediate web, the intermediate element has a cross-sectional area which largely corresponds to the overlapping sectional areas of the two crank pins. Moreover, each connecting rod is guided by means of an axial stop surface arranged on the large connecting rod eye of the adjacent connecting rod.
