摘要： The invention relates to a centrifugal pendulum absorber for a flywheel, including,
a plurality of pendulum weights being arranged circumferentially around a center axis of the centrifugal pendulum absorber, wherein,
the centrifugal pendulum absorber further including,
a plurality of closed compartments which are arranged circumferentially around the center axis, wherein at least one pendulum weight is arranged in each one of the plurality of closed compartments,
wherein a channel for fluid is provided at least between two abutting closed compartments, as seen in the circumferential direction, and wherein the channel for fluid fluidly connects the two abutting closed compartments.-

摘要： A pendulum weight for a centrifugal pendulum absorber for a flywheel of a vehicle includes a bearing surface that, when the pendulum weight is mounted radially outside of a central axis of the pendulum absorber, cooperates with a corresponding bearing surface provided on a separate part of the pendulum absorber, with respect to which separate part the pendulum weight is thereby configured to be movable along a predetermined pendulum path. The pendulum weight further includes a pocket formed in connection with the bearing surface, the pocket being configured to receive at least a portion of the separate part when the pendulum weight moves along the pendulum path. The pendulum weight includes an outward portion and a separate inward portion which are assemblable to form the pendulum weight, the outward portion being configured to be located radially outside of the inward portion with respect to the central axis when mounted.

摘要： The invention relates to a torsional damper (210) in a clutch disc arrangement (200) arranged to indicate damping performance of the torsional damper (210). The torsional damper (210) comprises a driven plate (211), an output hub (212), intermediate friction plates (213) arranged on either side of the driven plate (211) and a resilient member (214) arranged to press the intermediate friction plates (213) against the driven plate (211) or against the output hub (212) with a pressure force. The intermediate friction plates (213) and the resilient member (214) are rotationally fixed to the output hub (212) or the driven plate (211) forming a rotationally fixed stack (213, 214, 212; 213, 214, 211). The rotationally fixed stack (213, 214, 212; 213, 214, 211) comprises a detection friction plate (215) rotatably decoupled from the rotationally fixed stack (213, 214, 212; 213, 214, 211) and arranged in the rotationally fixed stack (213, 214, 212; 213, 214, 211).

摘要： A method and device for operating a powertrain of a motor vehicle are provided, wherein the powertrain includes an internal combustion engine, a transmission and a friction clutch arranged there between in order to control a power flow between the internal combustion engine and the transmission. The method includes the steps of detecting clutch judder, analyzing clutch judder, and determining a type of clutch judder. Based on determined type of clutch judder the method further includes selecting a udder countermeasure from a number of predetermined judder countermeasures and executing selected judder countermeasure. Detected clutch judder can be taken care of in an efficient way and future clutch judder may be prevented.
