Abstract
A vibration damper includes a cylinder to which a clamp-shaped attachment part is fastened, wherein the attachment part has a tubular body which contacts an outer lateral surface of the cylinder and has at both ends thereof radial tabs which are spaced apart in circumferential direction and by which a pre-loading in circumferential direction is introduced in the tubular body by clamping devices, wherein the tubular body has an elongation portion oriented in circumferential direction of the lateral surface of the cylinder.
Claims2
A vibration damper (1) comprising:
- a cylinder (3) and a clamp-shaped attachment part (7) fastened to said cylinder (3);
- said attachment part (7) comprising a tubular body (9) contacting an outer lateral surface (5) of said cylinder (3) and a pair of spaced apart radial tabs (11;
- 13) extending from said tubular body (9) for introducing a pre-loading in a circumferential direction in the tubular body (9);
- and wherein said tubular body (9) has an elongation portion (19;
- 29) permitting stretching of said tubular body in a circumferential direction of said lateral surface (5) of said cylinder (3);
- wherein said elongation portion (19) is formed by a cross section reduction of said tubular body (9);
- wherein said tubular body has al least one opening therein and said cross section reduction is formed by an edge web (29) bordering said opening (23) in said tubular body (9);
- wherein a second cross section reduction is formed by at least one edge cutout (25) in said tubular body (9);
- and
- wherein said at least one edge cutout (25) is formed so as to be offset in circumferential direction relative to a closest opening of said at least on opening (23) in said tubular body (9).
