Abstract
A torque transmission device particularly for a clutch disc unit to be used in a clutch assembly of an internal combustion engine comprises a hub member rotatable about an axis and a torque input member mounted on the hub member for angular movement with respect to the hub member about the axis of the hub member. A main damping unit and an idling damping unit are arranged for torque transmission from the torque input member to the hub member. A main damper input unit of the main damping unit is connected to the torque input member. A main damper output unit of the main damping unit is connected to an idling damper input unit of the idling damper unit and an idling damper output unit of the idling damper unit is connected to the hub member. A centrifugal mass-controlled locking member is provided for selectively permitting or locking angular relative movement of the main damper output unit with respect to the hub member. The angular movement of the main damper output unit with respect to the hub member is limited by interengaging abutment members having an angular play with respect to each other. The centrifugal mass-controlled locking member cooperates with these abutment members s…
