Abstract

A spring steel, liquid-damped shaft coupling in which the torque is transmitted between an inner part and an outer part coaxial therewith by means of radial spring elements disposed in discrete liquid-filled chambers, the liquid in any chamber being displaced, in response to a relative movement, by the spring elements into the adjacent chamber; outwardly axially parallel torsion spring elements are provided on the radial spring elements and connect the same to the outer coupling part. To increase the torsional resilience, therefore, a torsion tube is connected to each radial spring element and projects axially on one side relative to the radial spring element; and a torsion bar extends in the torsion tube, is frictionally secured to the projecting end thereof, and at its other end engages in the outer coupling part at a distance from the radial spring element in such a way as to rotate solidly with the outer coupling part.
