摘要： A spring damper for a motor vehicle drive train includes a primary part, a secondary part, a hub element, a first overload protection coupling operatively inserted between the secondary part and the hub element and a second overload protection coupling. The secondary part is rotatably received relative to the primary part in a spring-damped manner. The first overload protection coupling includes an output and the second overload protection coupling is operatively inserted between the output and the hub element. The second overload protection coupling is arranged radially within the first overload protection coupling. The first overload protection coupling is closed below a threshold of a torque to be transmitted, and the first overload protection coupling releases a relative rotation between the secondary part and the hub element above the threshold.
