Abstract
A torsional vibration damper includes a primary element with at least one primary driver, a secondary element with at least one secondary driver, at least one spring device between the primary and secondary drivers for resiliently elastic coupling of the primary and secondary elements, and at least one end block arranged on an end side of the spring device. The primary element is rotatable relative to the secondary element from a neutral position into a first position, in which the primary driver is supported only on the spring device, and from the first position onward into a second position, in which the primary driver is supported on the spring device and on the end block. In the first and second positions of the primary element, torque of the torsional vibration damper can be transmitted exclusively directly between the primary driver and spring device.
