Divided gear wheel for an automatic power transmission system

A divided gear wheel (100, 200), for an automatic power transmission system (1), wherein the divided gear wheel (100, 200) comprises

• an inner part (130, 230), being engageable with a shaft (10, 20) and
• an outer part (110, 210), comprising teeth (115, 215), adapted for torque transmission to another gear wheel, wherein
• the inner part (130, 230) and the outer part (110, 210) have a common rotational axis, and wherein the inner part (130, 230) is at least partially arranged within the outer part (110, 210),
• the inner part (130, 230) being coupled to the outer part (110, 210) by means of two elastic elements (154, 156, 254, 256), so that the inner part (130, 230) is arranged angularly deflectable with respect to the outer part (130, 230) around the common rotational axis, wherein
• the inner part (130, 230) and the outer part (110, 210) are adapted to rotate with the same angular speed if the elastic elements (154, 156, 254, 256) are fully loaded, wherein
• the first elastic element (154, 254) is partially arranged within the second elastic element (156, 256) and protrudes out of the second elastic element (156, 256) on a front face, wherein
• a spring rate of the first elastic element (154, 254) is lower than a spring rate of the second elastic element (156, 256) and wherein
• the inner part (130, 230) comprises engagement means (131, 231) that are adapted to engage with an engaging part (30, 60) of an automatic power transmission system (1), wherein upon engagement, the inner part (130, 230) is torque proof engaged with a shaft.
