초록

A hydrokinetic torque converter includes an impeller cover and bypass clutch located within the impeller housing. The impeller cover has welded to it a clutch plate, which carries friction material adjacent the clutch piston. The piston has legs that extend axially into engagement with helical springs carried in a damper assembly arranged in series with the damper between the impeller cover and the input shaft of the transmission. The springs are located in a retainer that accommodates two, three or four springs, as required by the torque requirements of...
