Title:

DISC BRAKE PISTON EMBODIED BY DRAWING

Document Type and Number:

WIPO Patent Application WO/2001/077547

Kind Code:

A1

Abstract:

The invention is embodied by drawing and comprises an outer cylindrical wall (1) provided with a slot (2). An inner space of a piston is formed with the aid of a cylindrical surface (3) which is adjacent to an end (4) and covering the slot (2) level along the piston axis, and a cylindrical surface (5) adjacent to a bottom (6). The surfaces (3) and (5) have different diameters: the diameter of the surface (3) adjacent to the open end (4) is smaller than the diameter of the cylindrical surface (5) adjacent to the bottom. Increasing the piston walls in the region of the slot makes it possible to choose a value (a) enabling said region to withstand working axial loads, without increasing a value (b) beyond a magnitude enabling remaining parts of the piston walls to withstand the working axial loads.
