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.
A spring damper for a motor vehicle drive train, comprising a primary part, a secondary part which is rotatably received relative to the primary part in a spring-damped manner, and a first overload protection coupling which is operatively inserted between the secondary part and a hub element and which is permanently closed below a threshold of a torque to be transmitted and releases a relative rotation between the secondary part and the hub element above said threshold at least in the event of an abrupt torque to be transmitted, wherein a second overload protection coupling is operatively inserted radially within the first overload protection coupling between an output of the first overload protection coupling and the hub element.
