Coupling means for conformal and zündfolgerichtigen connecting engine parts

Coupling means (2), said internal combustion engine parts (1a, 1b) during operation of at least one engine part (1a, 1b) are conformal and zundfolgerichtig connectable with a claw coupling (5) and a friction clutch (6), said claw coupling (5) and the friction clutch (6) arranged parallel to each other and are switchable independently of each other, and one hand with a first internal combustion engine part (1a) and on the other hand with a second engine part (1b) are operatively connected, wherein by means of the friction clutch (6), the engine parts (1a, 1b) are connectable and by means of the dog clutch (5a) of the engine parts (1a, 1b) are conformal and zundfolgerichtig connectable, said dog clutch (5) comprises several, over the periphery of the dog clutch (5) are not equally spaced claws (3) and associated claw pockets (4), so that the engine parts (1a, 1b) by means of the dog clutch (5) only at a particular Wi nkelzuordnung be connected, and is provided a damping device (21) with a contact surface (22) in the jaw pocket (4), wherein the damping device (21) as an intermediary between claw (3) and-mouth pocket (4) (as a part of the respective jaw pocket 4) is formed and the contact surface (22) forms a part of the jaw pocket (4).
