Abstract
A damping device includes a cylinder which is under pressure and which has a connection opening for a mount-on part which is fastened to an outer surface of the cylinder by means of an annular tensioning band element. The tensioning band element encircles the cylinder and the mount-on part on a circumferential region and, by its pretensioning, exerts a holding force on the mount-on part. The tensioning band element is underdimensioned in relation to the cross section of the cylinder and mount-on part and the distance between the two structural component parts and is expanded in a final mounting position in relation to a pre-mounting state in order to apply the pretensioning.
Claims7
A damping device comprising:
- a cylinder (3) under internal pressure having an outer surface and a connection opening;
- a mount-on part (7);
- an annular tensioning band element (9) for fastening said mount-on part (7) to said outer surface so as to cover said connection opening;
- said cylinder and said mount-on part having a cross section and a distance therebetween;
- said tensioning band element (9) encircling a circumferential region of each of said cylinder (3) and said mount-on part (7) and exerting a holding force on said mount-on part (7) by pretensioning;
- said tensioning band (9) being in continuous and uninterrupted contact with all of the circumferential region of said cylinder (3) that said tensioning band encircles to exert a holding force;
- said tensioning band element (9) being constructed so as to be under-dimensioned in relation to the cross section of said cylinder and of said mount-on part and the distance between said cylinder and said mount-on part (7);
- said tensioning band element being expanded in a final mounting position in relation to a premounting state so as to apply said pretensioning.
