Title (EN) SILENCER FOR LEAF SPRING, AND LEAF SPRING
(FR) SILENCIEUX POUR RESSORT À LAMES ET RESSORT À LAMES
(JA) 重ね板ばね用サイレンサおよび重ね板ばね
Abstract:
(EN) Provided is a structure of a silencer for leaf springs capable of preventing squeaking noise and of improving durability. These leaf spring silencers (1) are arranged between the leaves (60a-60c) which configure the leaf spring (6) and which are adjacent in the stacking direction of the leaves (60a-60c), in these arrangement positions, the leaf spring silencers (1) have a thickness (d1, d2) greater than the maximum value of the gaps (t1, t2) occurring, in the vehicle where the leaf spring (6) is assumed to be mounted, between adjacent leaves (60a-60c) due to flexure of the leaf spring (6). In the arrangement positions between the adjacent leaves (60), a gradient is added in the thickness of the leaf spring silencers (1) such that the leaf spring silencers (1) becomes thicker nearer to the end of the leaf springs (6) in the longitudinal direction (d2>d1).
(FR) L'invention porte sur une structure d'un silencieux pour ressorts à lames qui permet d'éviter le bruit de grincement et d'améliorer la durabilité. Ces silencieux de ressort à lames (1) sont agencés entre les lames (60a-60c) qui constituent le ressort à lames (6) et qui sont adjacentes dans la direction d'empilement des lames (60a-60c), dans ces positions d'agencement, les silencieux de ressort à lames (1) ont une épaisseur (d1, d2) supérieure à la valeur maximale des espaces libres (t1, t2) qui se forment, dans le véhicule dans lequel le ressort à lames (6) est supposé être monté, entre les lames adjacentes (60a-60c) suite à la flexion du ressort à lames (6). Dans les positions d'agencement entre les lames (60) adjacentes, un gradient est ajouté dans l'épaisseur des silencieux de ressort à lames (1) de telle sorte que les silencieux de ressort à lames (1) s'épaississent dans le sens qui se rapproche de l'extrémité des ressorts à lames (6) dans la direction longitudinale (d2>d1).
(JA)  きしみ音を防止すると共に耐久性を向上させることが可能な重ね板ばね用のサイレンサの構造を提供する。重ね板ばね用サイレンサ1は、重ね板ばね6を構成する複数の板ばね60a~60cのうち、これら板ばね60a~60cの重ね方向において隣り合う板ばね60a~60c間に配置され、その配置位置において、重ね板ばね6の搭載車両が想定している、この重ね板ばね6の撓みによる隣り合う板ばね60a~60c間の隙間t1、t2の最大値より大きな厚さd1、d2を有する。また、重ね板ばね用サイレンサ1は、隣り合う板ばね60間の配置位置において、重ね板ばね6の長手方向端部に近づくほど厚くなるように(d2>d1)、重ね板ばね用サイレンサ1の厚さに勾配が付けられている。
