Abstract
An installation for damping torsional vibrations in a gear drive, especially between the crankshaft and an output shaft of internal combustion engines, in which a gear wheel on the output shaft is connected with the output shaft by a friction clutch and an elastic coupling connected operatively in parallel thereto. To obtain a space-saving and operationally reliable structural unit to be assembled in a simple manner from preassembled units, the elastic coupling includes an inner coupling half and an outer coupling half each having radially directed webs as rotary abutments of interposed rubber elements; the outer coupling half is rigidly connected with the gear wheel and the friction clutch is arranged between the end faces of the gear wheel and the webs of the outer coupling half and is held centered by a prestressed spring element between these end faces up to assembly on the output shaft.
