Method for riveting leaf springs with a pressure plate of a friction clutch, a rivet support device, a press device and a friction clutch for a motor vehicle

摘要

The invention relates to a method for riveting leaf springs (5) with a pressure plate (1) of a friction clutch (2), the method comprising at least the following steps: a. Positioning the pressure plate (1) to the clutch cover (4); b. Positioning the at least one plate rivet (6) in corresponding through openings (7, 8, 9, 10) in the pressure plate (1) and in the relevant leaf spring (5); c. in a riveting process, compressing the at least one plate rivet (6), so that the leaf spring in question (5) is axially fixed to the pressure plate (1). The method proposed here is primarily characterized in that before step c. in one step d. a support element (11) on the cover side of the relevant leaf spring (5) is arranged in a radial overlap with the clutch cover (4) such that an axial pressing force (12) of a riveting instrument (13) acting on the at least one plate rivet (6) from the support element ( 11) is received in such a way that when the axial pressing force (12) is applied, a rivet head (14, 15, 16, 17) is held or formed by the support element (11). With the method proposed here and the corresponding rivet support device, a separate pre-assembly of the pressure plate and leaf springs is not necessary.
