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.

Crankshaft drive of an internal-combustion engine of V-type

The invention relates to a crankshaft drive for an internal-combustion engine of V-type with a crankshaft, which has two mutually offset crank pins per throw, which pins are interconnected via an intermediate web. In order both to minimize the amount of machining required on the intermediate web and to ensure an optimum axial guidance of two connecting rods mounted on the crank pins, the intermediate web has an axial stop collar on either side and the intermediate web is of an enlarged design such that the axial stop surface of the connecting rods cannot jut out from the projected area of the intermediate web in any crankshaft position.
