Abstract:
1. A vibration-damping mounting device for a vehicle assembly having an associated receiving opening, the device comprising: a stay bolt including a connecting journal, via which the device is configured to be connected to the vehicle assembly, and a threaded shank with an external thread; a sleeve-shaped elastic damping element which is engaged through by the stay bolt and has a receiving groove which is open to the outside and is configured to be inserted into the associated receiving opening; a clamping sleeve which is guided by the stay bolt; a bearing shoulder; a screw element with an internal thread, which is screwed onto the threaded shank in order to move the clamping sleeve axially on the stay bolt against the elastic damping element in such a way that, in a clamped state, the elastic damping element is both widened radially and shortened axially; and a disk arranged between the bearing shoulder and the elastic damping element, the clamping sleeve extending through the disk and into the elastic damping element with the disk being configured in such a way that a first friction force between the elastic damping element and the disk is greater than a second friction force between the disk and the bearing shoulder, wherein the clamping sleeve and the screw element are configured as a single-piece clamping element defining an axis with the bearing shoulder extending substantially perpendicularly to the axis and seamlessly from the clamping sleeve and the screw element, an axial force which is generated by the clamping element as a result of a screwing-on movement acting via the bearing shoulder on the elastic damping element, wherein the external thread on the threaded shank includes at least one region having a changed lead, which is different from adjacent leads, configured to increase clamping action between the screw element and the threaded shank at a position of the screw element on the threaded shank at which the at least one region having the modified lead engages the internal thread of the screw element, and wherein an undercut is defined in the bearing shoulder and provides a defined annular contact region between the bearing shoulder and the disk that is spaced apart from the clamping sleeve, and the undercut is disposed between the annular contact region and the clamping sleeve.
