BRAKE PAD PIN AND AXIALLY CONSTRAINING ELASTIC ELEMENT ASSEMBLY AND INTERACTION METHOD

One aspect of the present invention relates to a brake pad pin and axially constraining elastic element assembly (1), wherein said assembly (1) comprises a brake pad supporting pin (2) comprising a pin body (4), which extends along a pin axis (X-X) between a head end (5) and a tip end (6), wherein said pin body (4) comprises in succession along said axial direction (A-A) towards said tip end (6) at least one pin first portion (7) having at least one pin first portion diameter (D1), and a pin second portion (8) having at least one pin second portion diameter (D2), wherein said at least one pin second portion diameter (D2) is greater than said at least one pin second portion diameter (D1); and wherein said assembly (1) comprises an elastic element (3) arranged on said pin body (4) at least at said pin first portion (7), wherein said elastic element (3) has at least one elastic element inner diameter (Dpi) and at least one elastic element outer diameter (DpE), wherein said at least one elastic element outer diameter (DpE) is either greater than or equal to said at least pin second portion diameter (D2), and wherein said at least one elastic element inner diameter (Dpi) is smaller than said at least one pin second portion diameter (D2), wherein said pin body (4) comprises a pin third portion (9) arranged between said pin first portion (7) and said pin second portion (8), wherein said pin third portion (9) has at least one pin third stretch (10) having at least one pin third diameter (D3), which is greater than said at least one elastic element inner diameter (Dpi), wherein said elastic element (3) comprises an elastic element inner profile (13) facing towards said pin body (4), wherein said pin head third portion (9) comprises a head portion third profile (11) which connects said pin first portion (5) and said pin second portion (6), wherein, when said pin head third portion (9) is biased towards said elastic element (3) or vice versa, said pin third portion profile (11) is wedged at least partially into said elastic element inner profile (13) so that said pin third portion stretch (7) biases at least said elastic element (3) at least in a radial direction (R-R) outwards with a biasing force (F). Un aspect de la présente invention concerne un ensemble broche de plaquette de frein et élément élastique à contrainte axiale (1), ledit ensemble (1) comprenant une broche de support de plaquette de frein (2) comportant un corps de broche (4), qui s'étend le long d'un
