The pneumatic suspension device, suitable for transmitting torque, consists of a vibration-damping pneumatic ring, the inner surface of which rests on a rim connected to the part of the machine which must be free from vibration (for example, a hydraulic engine (12) directly flanged on a reduction unit (13), both made integral with a bracket (9) and a frame (8)), while the outer surface of the pneumatic ring (1) is gripped by a series of S-shaped jaw elements (3, 3') bolted onto a support ring (4) welded to the inner cylindrical wall of the vibrating drum (5). Said S-shaped gripping elements (3, 3') are secured, at the ends opposite those fixed to the support ring (4), to a symmetrical pair of metal rings (20 and 20') which are pressed against the sides of the pneumatic ring.
