Embodiment Construction

[0025] figure 1 Shows a partial sectional view of a torsional vibration damper 1 configured according to the invention as a dual mass flywheel, which can be used, for example, in a drivetrain (not shown) of a motor vehicle intended for hybrid applications used in . The pre-damper and the centrifugal pendulum are integrated in the torsional vibration damper 1 . The torsional vibration damper 1 is connected on the drive side to the internal combustion engine and on the output side to a shaft or clutch. A torsional vibration damper 1 , also known as a torsional vibration damper, comprises on the side facing the internal combustion engine a primary part 2 , also called an input part, and on the output side a secondary part 3 , also called an output part, which The primary part and the secondary part are jointly rotatable about an axis of rotation and are rotatable in a limited manner relative to each other. In this case, the primary part 2 and the secondary part 3 are connected...

Abstract

The invention relates to a torsional vibration damper (1), which is designed as a dual mass flywheel having a primary part (2) and a secondary part (3), which can be rotated about an axis of rotation and can be rotated relative to one another, and which are connected by means of a damping device (4) comprising a curved spring, wherein the arc spring is supported by means of one end on a stop of the primary part (2) and by means of the other end on a flange wing (7) of a carrier flange (5) associated with the secondary part (3), to which carrier flange a pendulum mass (22) of the centrifugal pendulum (25), which pendulum mass is arranged so as to be movable on both sides, is fastened, the torsional vibration damper (1) comprises a pre-damper (10) which is connected to the carrier flange (5) at a distance from the pendulum mass (22) on the circumferential side.

Description

technical field [0001] The invention relates to a torsional vibration damper designed as a dual-mass flywheel for use in a powertrain of a motor vehicle driven by an internal combustion engine, comprising a primary part and a secondary part, the primary The component and the secondary part are rotatable about an axis of rotation and can be twisted relative to each other, and the primary part and the secondary part are connected via a damping arrangement comprising an arc spring, wherein the arc spring is supported by one end on the primary part On the stop and by means of the other end on the flange wings of the carrier flange associated with the secondary part, on which the pendulum weights of the centrifugal pendulum, which are arranged movably on both sides, are also fastened . Background technique [0002] It is known to use torsional vibration dampers in the form of dual-mass flywheels for damping torsional vibrations in the drive train of a motor vehicle operated with...
