Dual mass dog collar and/or dual mass dog hub for a power transmission system

A dual mass dog collar (1), of a dog clutch wherein the dual mass dog collar (1) comprises

• an inner part (40) being torque proof engaged with an assigned dog hub or with
• an assigned shaft, comprising engagement means (41) on the inner circumferential surface and
• an outer part (50) comprising on at least one of its surfaces engagement means (60), adapted for torque transmission to/from an engageable free gear wheel, wherein
• the inner part (40) and the outer part (50) have a common rotational axis, wherein
• the inner part (40) is at least partially arranged within the outer part (50), wherein
• the inner part (40) and the outer part (50) are arranged concentrically to the assigned shaft, wherein
• the inner part (40) is arranged angularly deflectable with respect to the outer part (50) around the common rotational axis, wherein
• the inner part (40) is coupled to the outer part (50) by means of a first elastic element (70) and a second elastic element (80) wherein
• the elastic elements (70, 80) are positioned in a parallel configuration, wherein
• Each one of the elastic elements (70, 80) are received within at least one compartment formed by the inner part (40) and the outer part (so), and wherein
• the dual mass dog collar (1) is configured axially movable along the assigned dog hub or shaft guided by the provided engagement means (201) of the assigned shaft due to the interaction of the engagement means (201) of the assigned shaft with the corresponding engagement means (41) of the inner part (40).
