La présente invention concerne une plaque de friction utilisée dans unThe present invention relates to a friction plate used in a
frein à disque et, plus particulièrement une technique pour supprimer le phénomène de grincement dans un frein à disque Le phénomène du grincement dans un frein à disque est observé fréquemment en appliquant le frein avec des sons intenses et aigus produits et, il est fortement exigé de supprimer un tel phénomène Le phénomène de grincement est basé sur des vibrations de friction dans une surface glissante de friction d'une plaque de friction du frein à disque qui contacte de façon glissante un disque en rotation en appliquant le frein à disque et les vibrations induisent les vibrations de résonnance dans les organes concernés Cependant, puisque le système 15 de vibration est compliqué il est très difficile de supprimer complètement un tel phénomène et diverses propositions ont été faites par rapport aux parties disc brake and, more particularly, a technique for suppressing the phenomenon of squeaking in a disc brake The phenomenon of squeaking in a disc brake is frequently observed by applying the brake with intense and sharp sounds produced and, it is strongly required to to suppress such a phenomenon The phenomenon of squeaking is based on frictional vibrations in a sliding friction surface of a disc brake friction plate that slidably contacts a rotating disk by applying the disc brake and the vibrations induce However, since the vibration system is complicated, it is very difficult to completely eliminate such a phenomenon and various proposals have been made with respect to the parts in question.
respectives comprenant la plaque de friction. respective ones comprising the friction plate.
Généralement, on exige que le matériau de friction 20 de la plaque de friction soit supérieur dans la force de friction et dans la qualité antiusure, cependant, ces caractéristiques sont contradictoires au phénomène de grincement Principalement, lorsque la force de friction de la plaque de friction est améliorée le phénomène de grincement est incité et la contremesure pour supprimer le phénomène de grincement diminue quelquefois la force de Generally, friction material 20 of the friction plate is required to be superior in frictional strength and in anti-wear quality, however, these characteristics are in conflict with the grinding phenomenon. Principally, when the frictional force of the friction plate is improved the creak phenomenon is prompted and the countermeasure to suppress the creak phenomenon sometimes decreases the strength of

Selon la présente invention, la densité du matériau de friction de la plaque de friction est variéedans la According to the present invention, the density of the friction material of the friction plate is varied in the
direction de rotation du disque.direction of rotation of the disc.
Ainsi, la distribution de la pression de surface sur la plaque de friction en appliquant celle-ci contre le disque est variée dans la direction de rotation du disque et, comme résultat, les caractéristiques de vibration de la plaque de friction dans la direction de rotation du disque sont changées effectivement, ainsi il est possible de supprimer les vibrations de résonnance De plus, la compressibilité du matériau de friction peut également être changée dans la direction de rotation du disque et, ainsi la diminution de la force de friction et les caractéristiques Thus, the distribution of the surface pressure on the friction plate by applying it against the disc is varied in the direction of rotation of the disc and, as a result, the vibration characteristics of the friction plate in the direction of rotation. of the disc are actually changed, so it is possible to suppress the resonance vibrations In addition, the compressibility of the friction material can also be changed in the direction of rotation of the disc and, thus the decrease of the frictional force and the characteristics
anti-usure peuvent être minimisées. anti-wear can be minimized.
De préférence, des zones de haute densité et de basse densité du matériau de friction sont agencées alternativement dans la direction de rotation du disque pour définir un motif à raies ou bandes ou en damier Preferably, areas of high density and low density of the friction material are arranged alternately in the direction of rotation of the disc to define a striped or striped pattern or checkerboard pattern.
