Abstract
Spring pack for a clutch arrangement of a motor vehicle drivetrain. The spring pack has a first ring element, has a second ring element and has a multiplicity of individual springs which are coupled to the first and the second ring elements such that the first and the second ring elements are movable relative to one another in an axial direction in a manner coupled by the springs. The first and the second ring elements each have an inner circumferential section and an outer circumferential section. At least one of the first and the second ring elements has, in the region of at least one of its inner circumferential section and its outer circumferential section, a multiplicity of radially deformable elements which are designed so as to enable the spring pack to be centered in relation to a ring surface or so as to enable the spring pack to be mounted captively on the ring surface.
