Abstract
(EN)
Router bit assembly (18, 22) for the sides (20, 24) of the bowl (10) of an earthmoving machine (12). The router bit assembly is of two-piece construction and includes a router bit (42) and a holder (26) which, when secured to the vertical side walls (20, 24) of the bowl (10), captures the bit (42) between the holder (26) and the vertical side wall (24). The rear edge (56) of the bit (42) is held against the leading edge (58) of the corner (25) of the vertical side wall (24) by the holder (26). The two-piece router bit assembly advantageously reduces the amount of metal that is discarded when the life of the bit is expended.

Un ensemble formant un couteau (18, 22) pour les parois laterales (20, 24) d"un plateau (10) d"une machine de terrassement (12). L"ensemble de couteaux est une construction en deux pieces et comprend un couteau (42) et un support (26) qui, lorsqu"il est fixe aux parois laterales verticales (20, 24) du plateau (10) maintient le couteau (42) entre le support (26) et la paroi laterale verticale (24). Le bord arriere (56) du couteau (42) est maintenu contre le bord d"attaque (58) du coin (25) de la paroi laterale verticale (24) par le support (26). L"ensemble formant couteau a deux pieces reduit de maniere avantageuse la quantite de metal que l"on jette a la fin de la duree d"utilisation du couteau.
