Embodiment Construction

[0024] Figures 1 to 3The clutch disk 1 with the centrifugal pendulum 2 is shown in section, front view and 3D oblique view. The clutch disc comprises an input part 5 formed by flange parts 3 , 4 and an output part 8 formed by a flange part 7 , wherein the flange part 3 carries a friction lining 6 , the output part can be connected to the flange in a rotationally fixed manner. The hub 9 to which the component 7 is connected is connected in a rotationally fixed manner to the transmission input shaft. The input part 5 and the output part 8 are able to rotate in a limited manner about the axis of rotation D against the action of a spring arrangement 11 formed by a helical spring 10 and form a torsional vibration damper here.

[0025] The centrifugal pendulum 2 is assigned to the output part 8 of the clutch disk 1 . For this purpose, the support flange 12 of the centrifugal pendulum 2 is connected to the hub 9 in a rotationally fixed manner by means of screws 13 and / or abuts aga...

Abstract

The invention relates to a centrifugal force pendulum (2, 2a) having a carrier flange (12, 12a) and having at least one pendulum mass (14, 14a) which is arranged so as to be pivotable in the circumferential direction and radially to a limited extent with respect to the carrier flange by means of rolling bodies (22) which roll on raceways (49) of cutouts (17) provided in the carrier flange and in the pendulum masses, and also to a clutch disc (1) having the same. To attain improved vibration isolation of rotary vibrations in particular of a centrifugal force pendulum arranged on a small diameter of the clutch disc, the at least one pendulum mass is guided in the raceways so as to rotate about the mass centre of itself during a deflection with respect to the carrier flange.

Description

technical field [0001] The invention relates to a centrifugal force pendulum with a bearing flange and at least one pendulum mass, the at least one pendulum mass being arranged relative to the bearing flange by means of an The rolling bodies rolling on the raceways of the recesses in the bearing flange and in the pendulum mass are arranged in the circumferential direction and are arranged in a radially limited pivotable manner. Background technique [0002] Centrifugal pendulums in the powertrain of a motor vehicle alone or in combination with other rotational vibration isolation devices such as torsional vibration dampers in clutch discs or in torque regulators of friction clutches, dual mass flywheels, rotational vibration dampers and used in similar components and is known, for example, from DE 10 2009 042 831 A1. A generic centrifugal pendulum is formed by a carrier flange, preferably arranged around the axis of rotation of the transmission input shaft or the crankshaft...
