Abstract:
1. A clutch for a construction machine, the construction machine having a machine frame, a working drum supported from the machine frame, a combustion engine supported from the machine frame, and a drive train including a drive shaft and an output shaft connecting the combustion engine and the working drum, the clutch comprising: a drive side including at least one drive side clutch element connected to the drive shaft; an output side including at least one output side clutch element connected to the output shaft; wherein at least one of the drive side and the output side includes a fixed part and a movable part engageable with one another and having a rotational play therebetween; and a clutch brake operable during engagement of the clutch to provide a frictional rotational coupling force between the drive side and the output side to reduce relative rotational motion between the fixed part and the movable part the clutch brake being separate from the clutch elements and the clutch brake being configured such that the frictional rotational coupling force of the clutch brake is transmitted between the drive side and the output side without passing through the operably engaged clutch elements.
