Embodiment Construction

[0029] figure 1Shown is a dual-mass flywheel (ZMS) 1 , also known as a torsional damper, which is arranged in the drive train of a vehicle with a crankshaft (not shown) of an internal combustion engine and a vehicle clutch (not shown), in particular embodied as a double clutch. out). The torque of the internal combustion engine is transmitted here from the vehicle clutches to the drive wheels, for example via a switching gear and a differential gear in conjunction with a cardan shaft. The dual-mass flywheel 1 comprises a primary part 2 , also called primary mass, and a secondary part 3 or secondary mass, which are limited relative to each other about an axis of rotation 5 against the force of a spring-damper system 4 twist. The primary part 2 comprises a drive-side disk flange 7 fastened to the crankshaft flange 6 , which surrounds the spring-damper system 4 with an outer bent leg 8 .

Abstract

The invention relates to a dual mass flywheel (1) comprising a primary part (2) and a secondary part (3) that can be rotated together in relation to each other about an axis of rotation (5) in a restricted manner. A spring damper arrangement (4) including a torsion spring (14) and a friction device (20) are provided between the primary part (2) and the secondary part (3). The secondary part (3) embodied as a single component forms outer flange sections (13) that cooperate with the torsion springs (14), as well as an output hub (11). A holding element (16, 33) used to centre (15) the secondarypart (3) is arranged on the primary part (2). The dual mass flywheel (1) is covered by a metal sheet (9) on the output side.

Description

technical field [0001] The invention relates to a dual-mass flywheel consisting of a primary part and a secondary part which can be twisted relative to each other in a limited manner about an axis of rotation; A spring-damper system; a friction device with at least one friction ring loaded by spring force; and a centrifugal pendulum associated with the secondary part. Background technique [0002] Rotational vibration dampers are generally known. The rotational vibration damper serves to damp rotational or torsional vibrations in the drive train of a vehicle driven by an internal combustion engine in order to attenuate the vibrations originating from the internal combustion engine relative to the drive train to a certain extent and thereby increase driving comfort. . The preferably used dual-mass flywheel (ZMS) brings about effective vibration damping due to its low torsional stiffness in the usable speed range between no-load speed and maximum speed. When starting or sto...
