Abstract:
A torque damper can comprise a clutch piston arranged within a cover of a torque converter and can be adapted to be moved between a connected position and a non-connected position relative to the cover. Damper springs can be arranged along the circumference of the clutch piston. Connecting members can be arranged abutting against one end of the damper spring and adapted to connect a turbine arranged within the cover and the clutch piston via the damper spring. Damper holders can be arranged abutting against the other end of the damper spring and adapted to hold the damper spring against the compressive force applied to the damper spring from the connecting member. Guide sheets having wear resistance can be interposed between the circumference of the clutch piston and the damper spring and can be adapted to guide the damper spring. A torque input to the cover can be transmitted to the turbine via the clutch piston and the damper springs when the clutch piston is in the connected position. The guide sheets can be anchored to the damper holders and secured thereto immovably in the circumferential direction of the clutch piston.
