Abstract (en)
The linkage comprises a ternary link with first, second and third pivot connections and a follower link with first and second pivot connections. The first pivot connection of the ternary link is pivotally coupled to the rod end of the bucket actuating hydraulic cylinder. The second pivot connection of the ternary link is pivotally coupled to the excavator bucket. In addition, the excavator bucket is pivotally connected to the dipper stick. The follower link has a first pivot connection that is pivotally connected to the dipper stick and a second pivot connection that is pivotally connected to the third pivot connection of the ternary link. In one frame of reference, the third pivot connection of the ternary link is located between the first and second pivot connections of the ternary link. In addition, the third pivot connection of the ternary link lies above a plane defined by the first and second pivot connections of the ternary link. In another frame the second and third pivot connections of the ternary link define a plane below which the first pivot connection is located. Furthermore, the first pivot connection lies above a second plane which is perpendicular to the first plane and intersects the first plane at the third pivot connection.
Abstract (de)
Ein Bagger mit einem Löffelstiel (22) und einer Schaufel (26), die mittels eines Hydraulikmotors (30) verschwenkt wird, enthält ein Gestänge, das sich aus einem drei Lagerstellen (46, 48, 50) aufweisenden Betätigungslenker (44) und einem zwei Lagerstellen (50, 54) aufweisenden Führungslenker (52) zusammensetzt. Der Betätigungslenker (44) ist einenends mit der Schaufel (26) und anderenends mit dem Hydraulikmotor (30) verbunden und dazwischen an den Führungslenker (52) angeschlossen, der anderenends an dem Löffelstiel (22) angreift. Die mittlere Lagerstelle (50) des Betätigungslenkers (44) ist gegenüber der ersten und der zweiten Lagerstelle (46, 48) von dem Löffelstiel (22) weg versetzt. <IMAGE>
