CENTRIFUGAL PENDULUM DEVICE HAVING FRICTION-OPTIMIZED SPACER ELEMENTS FOR THE PENDULUM MASSES

摘要

The invention relates to a centrifugal pendulum device (1), used in a drive train of a vehicle driven by an internal combustion engine between a crankshaft of the internal combustion engine and a transmission input shaft of a transmission. The centrifugal pendulum device (1) comprises a carrier disk (2) formed as a flange and assigned to a flywheel element, and a plurality of pendulum masses (3, 4) arranged on both sides of the carrier disk (2), which, in the event of non-uniformity of rotation in the drive train, are displaced under the action of centrifugal force along running tracks (7, 8) in conjunction with rollers (6). In each case two pendulum masses (3, 4), together with further individual elements, are joined together by means of separate fastening elements to form a pendulum mass pack (5). For this purpose, each pendulum mass (3, 4) can run against the carrier disk (2) indirectly via a friction-optimized spacer element (11, 12), wherein the spacer elements (11, 12) are connected via an intermediate plate (13) which, when the pendulum mass pack (5) is installed, engages with play in a recess (14) in the carrier disc (2).
