A balancing element for balancing a friction clutch, including a balancing head for providing a balancing mass, and a shaft that is connected to the balancing head, is to be inserted into an opening in the friction clutch, and has a shaft end which points away from the balancing head and which includes a face pointing away from the balancing head substantially in the axial direction of the shaft. The shaft end has a weakening in the material in a subsection between the face and the balancing head in order for the shaft end to plastically deform radially outward in relation to the longitudinal axis of the shaft when a compressive force is applied to the balancing head in the axial direction. This especially allows the face of the shaft end to about a part of the friction clutch once the shaft has been introduced into a receiving opening in the friction clutch, and makes it possible to apply a compressive force to the balancing head in the direction of insertion, said compressive force being so great that the shaft end is plastically deformed in a particularly easy manner in the region of the weakening in the material such that a secure form-fitting connection is established, thereby preventing the balancing element from coming loose again even when the assembly space is tight and keeping the risk of the friction clutch becoming unbalanced low during the entire service life of the friction clutch.
A balancing element for balancing a friction clutch comprising a balancing head for providing a balancing weight and a shaft connected to the balancing head to be inserted in and extend through an opening of the friction clutch, the shaft comprising a shaft end essentially pointing away from the balancing head, having an end face essentially in an axial direction of the shaft and pointing away from the balancing head, the shaft end, in a part between the end face and the balancing head, comprising a weakening of material adapted for plastic deformation of the shaft end radially outward from a longitudinal axis of the shaft upon application of a compression force upon the balancing head in the axial direction, the weakening of material being axially spaced away from the end face of the shaft.
A method for balancing a friction clutch, comprising using a part of a friction clutch as a counter holder to form a closing head by plastically deforming an end of a shaft of a balancing element guided through an opening of the friction clutch, wherein the shaft includes a weakening of material adapted for plastic deformation upon application of a compression force in an axial direction, and the weakening of material is spaced away from axial end faces of the shaft.
