Abstract
The present invention is directed to a damper device for a torque converter. The torque converter comprises a casing, a turbine, a pump and a stator, an input shaft coupled to the pump through the casing, an output shaft coupled to the turbine a clutch plate slidably mounted on the turbine for frictional engagement with the casing, and a plurality of circumferentially extending springs for coupling the clutch plate to the turbine. The damper device comprises a support on the clutch plate for contacting the longitudinal surface of each of the springs and holdind the springs, the springs directly abutting the side surface of the clutch plate. End surface supporting members are coupled to the clutch plate for supporting the ends of each of the springs, the end surface supporting members being positioned in spaces between adjacent springs. Torque transmission members are mounted on the turbine and extend therefrom into the end surface support members, the torque transmission members engaging the end surface of the springs for transferring the rotation of the turbine to the springs and thereby to the clutch plate, wherein the fluctuations in torque between the turbine and clutch plate are dampened by the springs.
