Embodiment Construction

[0020] figure 1 A device 100 is shown which is integrated in the drive train of a motor vehicle with hybrid use for torque transmission.

[0021] The illustration is limited to the components of device 100 that are essential to the invention and which can be arranged in an originally not shown drive train of a motor vehicle that can be driven by means of an internal combustion engine and / or an electric drive. The drive hub 101 of the device 100 can be connected in a rotationally fixed manner to the crankshaft of the internal combustion engine, and the driven hub 102 of the device 100 can be connected in a rotationally fixed manner to the transmission. The driving hub 101 is connected with the flywheel 104 through the elastic disk 103, the flexible disk in the axial direction. Correspondingly, riveted connections are provided here as fastening means 105 , 106 . An intermediate flange 108 , on which a pendulum mass 111 with an integrated, movably arranged pendulum mass 111 , i...

Abstract

The invention relates to a device (100) for transmitting torque in a drive train of a motor vehicle having a hybrid application, wherein the motor vehicle can be driven by an internal combustion engine or an electric drive or by both simultaneously in a combined manner. The device (100), which can be inserted between the internal combustion engine and a transmission of the hybrid vehicle, comprises a flywheel (104) and a centrifugal pendulum (110), which includes a plurality of pendulum masses (111). For indirect decoupling of the centrifugal pendulum (110), an elastic disk (103) is provided,which connects the flywheel (104) to a drive hub (101) of the device (100).

Description

technical field [0001] The invention relates to a centrifugal pendulum according to the features of the preamble of claim 1 , which is integrated in a device for torque transmission in a drive train of a motor vehicle with hybrid applications, wherein the machine The motor vehicle can be driven by means of an internal combustion engine or an electric drive or a combination of both. Background technique [0002] Devices of this type are used, for example, to ensure the interaction of the internal combustion engine and the electric motor in drive trains of hybrid vehicles. In this case, such a device assumes the function of torque transmission from the internal combustion engine and / or the electric motor to the output shaft or to the downstream transmission. Furthermore, such a device includes a vibration-damping function, for which purpose, in particular, a centrifugal pendulum device is provided. Centrifugal pendulums are also suitable for damping vibrations occurring in h...
