Torque transmitting and torsion damping assembly

A torque transmitting and torsion damping assembly, particularly for the transmission of torque between an internal combustion engine and an input element of a change-speed transmission in a motor vehicle, comprising a first rotary unit normally receiving torque from the engine and a second rotary unit coaxial with said first unit and arranged to normally transmit torque to the transmission, said first and second units respectively comprising first and second flywheels and said second unit further comprising a clutch interposed between said second flywheel and the transmission, at least one of said flywheels being movable within predetermined limits axially relative to the other of said flywheels and said flywheels being angularly movable relative to each other;

• antifriction bearing means interposed between said flywheels;
• damper means interposed between said units to yieldably oppose angular movements of said flywheels relative to each other;
• actuating means operable to change the condition of said clutch between an engaged condition in which the clutch transmits torque between said second flywheel and the transmission and a disengaged condition, said one flywheel being arranged to move axially relative to said other flywheel in response to operation of said actuating means;
• and resilient means for biasing said flywheels axially relative to each other, said resilient means including a resilient element which reacts against one of said units and bears against the other of said units.

• antifriction bearing means interposed between said flywheels, said flywheels being angularly movable relative to each other;
• damper means disposed between said units to yieldably oppose angular movements of said flywheels relative to each other;
• and resilient means acting axially upon said second flywheel counter to the direction of application of said force during disengagement of said clutch, said resilient means comprising at least one diaphragm spring.

• antifriction bearing means interposed between said flywheels, said flywheels being angularly movable relative to each other and said bearing means including first and second races respectively rotatable with said first and second flywheels;
• damper means disposed between said units to yieldably oppose angular movements of said flywheels relative to each other;
• and resilient means including a resilient element which reacts against one of said units and bears against the other of said units so as to act against axial movements of said races relative to each other in one direction in engaged condition of said clutch.
