Patent ID: 7775335

Claim:
A mechanical stop mechanism for a torque converter ( 6 ), comprising a hub ( 22 ) for a turbine wheel ( 21 ); a damper hub ( 38 ) connected to a rotational vibration damper ( 27 ), rotational vibration damper ( 27 ) connected to a converter bridge coupling ( 26 ); and, a damper including a plurality of springs, a flange rotationally fixed to the damper hub, and a driving plate ( 30 ), wherein the driving plate ( 30 ) is for receiving a torque load, wherein the torque load is transferable from the driving plate ( 30 ) to the flange via the springs, wherein the driving plate ( 30 ) is connected to converter bridge coupling ( 26 ), wherein as soon as a maximum design load of rotational vibration damper ( 27 ) has been exceeded, relative rotation of hub ( 22 ), damper hub ( 38 ), and driving plate ( 30 ) causes drive plate ( 30 ) to directly engage hub ( 22 ) and to directly engage damper hub ( 38 ) to create a first torque path between driving plate ( 30 ) and hub ( 22 ) and a second torque path between driving plate ( 30 ) and damper hub ( 38 ).
