<p>The pneumatic suspension device according to the novel and improved principle of this invention, suitable for transmitting torque, is composed of a single toroid-shaped 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 exemple, a hydraulic engine (12) directly flanged on the reduction unit (13), both of which are made integral with the bracket (9) and frame (8), whereas the outer surface of the pneumatic ring (9) is gripped by a series of S-shaped jaw elements (3, 3 min ), bolted onto a support ring (4) welded to the inner cylindrical wall of the vibrating drum (5), said S-shaped jaw elements (3, 3 min ) having a profile such that each pair (3, 3 min ) of jaws, once fixed in position on said outer band of the toroidal pneumatic ring, forms therewith a single body damping the vibration of the drum (5). </p> |
