Abstract: 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.

Abstract: 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.

Abstract: A method for automatically warming up a clutch actuator for a clutch of a transmission in a vehicle, wherein the clutch actuator is operable by use of pressurized fluid and configured to actuate the clutch from an engaged to a disengaged state, and/or vice versa, the method including: identifying if a temperature is below a predetermined temperature value and if the clutch actuator is leaking, and if it is identified that the temperature is below the predetermined temperature value and that the clutch actuator is leaking; then repeatedly pressurizing the clutch actuator by use of the pressurized fluid until a state is reached indicative of the clutch actuator being functional, or until a maximum run out state is reached indicative of a faulty clutch actuator.
