Problems solved by technology

[0003] Although a friction clutch of this type with a two-part lever spring pin is characterized by a relatively high service fatigue strength and good maneuverability, it has also been shown in practice that the assembly of a friction clutch of this type is due to two A lever spring pin constructed in one piece can become relatively expensive
The two-part construction of the lever spring pin proves to be relatively difficult to assemble, especially when mounted between the housing and the lever spring

Embodiment Construction

[0032] The drawings are only of a schematic nature and serve only for the understanding of the invention. Identical elements are provided with the same reference numerals. Features of a single embodiment may be interchanged or supplemented.

[0033] figure 1 A schematic sectional view of a friction clutch 1 is shown, which can be used in particular as a starter clutch in a drive train of a motor vehicle, for example a passenger car, a truck or other commercial vehicles.

[0034] Friction clutch 1 in figure 1 shows the engaged, that is to say closed, state in which a force or torque transmission can be achieved / guaranteed. The friction clutch has a pressure plate 2 and a counterplate 3 between which a clutch disc 4 can be clamped or pressed for torque transmission. The compression plate 2 is connected in a rotationally fixed manner to a cover 5 designed as a housing cover. In this case, the pressure plate 2 is only displaceable in the axial direction A to a limited extent....

Abstract

The invention relates to a friction clutch for a powertrain of a motor vehicle, having a cover (5) on which a lever spring (6) is mounted by means of a lever spring pin (12), said lever spring pin having a shank (12) with a head (14), the outer diameter of which is larger than that of the shank. The shank is at least partially surrounded by a bushing (15), said bushing being force-locked with or bonded to the shank or the head.

Description

technical field [0001] The invention relates to a friction clutch for a drive train of a motor vehicle, such as a passenger car, truck or other commercial vehicle, which has a cover, a lever, in particular a lever spring preferably embodied as a disk spring, via which A lever spring pin is supported on the cover, wherein the lever spring pin has a shank, the lever spring pin has a head enlarged / widened relative to the outer diameter of the shank, and In this case, the shaft is preferably at least partially surrounded by a bushing along its axial extension. Background technique [0002] Such a friction clutch with a multi-part, in particular two-part, lever-spring bolt is known, for example, from DE 10 2012 215 273 A1 or DE 2013 214 702 A1. Friction clutches for motor vehicle drive trains each have a pressure plate which is connected to the housing cover in a rotationally fixed, but axially limited displaceable manner. In order to force the pressure plate in the axial direc...
