Abstract[English]
A spreading device (1) for brake pads (7), comprises: a central wire (2) with at least one attachment portion (2a), a first spring wire (3), a second spring wire (4), a first interface element (5), connecting the first spring wire (3) to the central wire (2), a second interface element (6), connecting the second spring wire (4) to the central wire (2), wherein the first spring wire (3) comprises: a bent portion (3b), two leg portions (3c1, 3c2), respectively connected to the bent portion (3b) at both sides, and two connecting portions (3a1, 3a2), being connected to the respective leg portion (3c1, 3c2), and wherein the second spring wire (4) comprises the same elements as the first spring wire (3) wherein the bent portion (3b) of the first spring wire (3) is spaced from the bent portion (4b) of the second spring wire (3) on the central wire (2). In one embodiment, one leg portion (3c1) of the first spring wire (3) crosses one leg portion (4c1) of the second spring wire (4), and the other leg portion (3c2) of the first spring wire (3) crosses the other leg portion (4c2) of the second spring wire (4). In another embodiment, each leg portion (3c1, 3c2; 4c1, 4c2) comprises at least one bow section (3d1, 3d2; 4d1, 4d2) including a total bow of more than 90°. By such designs, a more compact design, being in particular suitable for shorter brake pads for a separate parking brake caliper, can be enabled.[French]
L'invention concerne un dispositif d'écartement (1) pour plaquettes de frein (7) comprenant : un fil central (2) avec au moins une partie de fixation (2a), un premier fil à ressort (3), un second fil à ressort (4), un premier élément d'interface (5), reliant le premier fil à ressort (3) au fil central (2), un second élément d'interface (6), reliant le second fil à ressort (4) au fil central (2), le premier fil à ressort (3) comprenant : une partie courbée (3b), deux parties de patte (3c1, 3c2), respectivement reliées à la partie courbée (3b) des deux côtés, et deux parties de liaison (3a1, 3a2), étant reliées à la partie de patte respective (3c1, 3c2), et le second fil à ressort (4) comprenant les mêmes éléments que le premier fil à ressort (3), la partie courbée (3b) du premier fil à ressort (3) étant espacée de la partie courbée (4b) du second fil à ressort (3) sur le fil central (2). Dans un mode de réalisation, une partie de patte (3c1) du premier fil à ressort (3) croise une partie de patte (4c1) du second fil à ressort (4), et l'autre partie de patte (3c2) du premier fil à ressort (3) croise l'autre partie de patte (4c2) du second fil à ressort (4). Dans un autre mode de réalisation, chaque partie de patte (3c1, 3c2 ; 4c1, 4c2) comprend au moins une section d'arc (3d1, 3d2; 4d1, 4d2) comprenant un arc total supérieur à 90°. Par de telles conceptions, une conception plus compacte, étant en particulier appropriée pour des plaquettes de frein plus courtes pour un étrier de frein de stationnement séparé, est possible.
