Abstract:
(EN) In the present invention, an upper link (3) and a lower link (6) are connected via an upper pin (4). The end sections of the upper pin (4) are secured in pin fitting holes (16) of a pair of upper-pin pin boss sections (12). A cylindrical sliding surface (27a) of a bush (27) of the upper link (3) fits rotatably onto a diamond-like carbon (DLC) coating (25) of a center section of the upper pin (. The width (B) of the bush (27) is less than the width (A) of an upper-link-side pin boss section (20). Consequently, the cylindrical sliding surface (27a) does not overlap an unfinished coating region (25b) of an end section of the DLC coating (25), and burn-in in the unfinished coating region (25b) and peeling of the DLC coating (25) are suppressed.
(FR) Dans la présente invention, une tringle supérieure (3) et une tringle inférieure (6) sont reliées par l'intermédiaire d'une broche supérieure (4). Les sections d'extrémité de la broche supérieure (4) sont fixées dans des trous d'insertion de broche (16) d'une paire de sections de bossage de broche supérieure (12). Une surface de glissement cylindrique (27a) d'une douille (27) de la tringle supérieure (3) s'ajuste de manière rotative sur un revêtement de carbone sous forme de diamant amorphe (CDA) (25) d'une section centrale de la broche supérieure. La largeur (B) de la douille (27) est inférieure à la largeur (A) d'une section de bossage de broche côté tringle supérieure (20). Par conséquent, la surface de glissement cylindrique (27a) ne chevauche pas une région de revêtement non finie (25b) d'une section d'extrémité du revêtement CDA (25), et la surchauffe dans la région de revêtement non finie (25b) et le décollement du revêtement DLC (25) sont supprimés.
(JA) アッパリンク(3)とロアリンク(6)とがアッパピン(4)を介して連結される。アッパピン(4)は、両端部がロアリンク(6)の一対のアッパピン用ピンボス部(12)のピン嵌合孔(16)に固定される。中央部のDLCコーティング(25)の上にアッパリンク(3)のブッシュ(27)の円筒状摺動面(27a)が回転可能に嵌合する。ブッシュ(27)の幅(B)はアッパリンク側ピンボス部(20)の幅(A)よりも短い。従って、DLCコーティング(25)端部の不完全コーティング領域(25b)の上には円筒状摺動面(27a)が重ならず、不完全コーティング領域(25b)での焼き付きやDLCコーティング(25)の剥離が抑制される。
