摘要

A torsional vibration absorber, partic, for vehicle gearboxes, has a disc which can befixed by flange on to a shaft. This disc is elastically coupled circumferentially to a vibration ring via at least three rubber blocks which leave at least three elastomer spacers at regular intervals round the circumference in the gap between the disc and ring. These spacers are cured in position and also leave gaps and axial recesses which are axially open on one side to take other material. The spacers are vulcanised on to the inner wall of the ring; the material inserted into the recesses consists of flat and stable pieces which are pressed into the recesses and distort them so that the remaining gaps are less than 0.2mm. The pieces are preferably glass-filled polyamide.
