| 摘要 |
<p>The invention relates to a powder-metallurgically produced piston body for a piston-cylinder arrangement, particularly shock absorber pistons, comprising a one-piece piston body (6), the peripheral surface of which is provided with a revolving web (12) in a region bordering a final piston area (4.1). Said revolving web (12) protrudes the peripheral surface and is adjacent to longitudinal support webs (10) which extend to the other final piston area (5.1) and are disposed parallel to and at a distance from each other, and at least some of which are provided with at least one transversal groove (11.1) between the two final piston areas (4.1, 5.1). Two neighboring support webs (10) delimit a groove-shaped recess (11) which is open in the longitudinal direction at the end opposite the revolving web (12). A collar-shaped seal (9) made of a thermally deformable sealing material can be shaped onto the piston body (6) such that both the revolving web (12) and the support webs (10) are formed into the material of the collar-shaped seal (9) in the vertical direction, at least across a portion thereof.</p> |
