ABSTRACT:
In a multi-cylinder internal combustion engine, with a first crankshaft part and a second crankshaft part, a device for coupling the crankshaft parts at a predetermined relative angular position is provided. A friction clutch for pre-coupling the crankshaft parts and for attaining substantially the same speed of rotation has a first thrust element coupled to the first crankshaft part wherein the thrust element is rotatable over an angle relative to the first shaft between a first angular position and a second angular position. A clutch plate is coupled to the second crankshaft part for engaging the thrust element. Means are provided for actuating the first friction clutch wherein the thrust element is maintained in the first angular position during initial actuation of the friction clutch, and moves to the second angular position in response to a reversal in torque transmitted between the crankshaft parts. Engagement means for achieving positive locking engagement between the first shaft and the second shaft comprises a first engagement element mounted to the first crankshaft part to be axially displaced, and a second engagement element fixed to the second shaft part, wherein the engagement elements positively engage only at a predetermined relative angular position. The friction clutch includes means for preventing the engagement of the engagement elements when the thrust element is in a first angular position. Means are included for actuating the engagement means when the thrust element is in the second angular position.
