Apparatus for the frontal connection of equipment to agriculturally usable motor vehicles, in particular farming tractors

摘要

To bring not only a front-mounted hydraulic three-part linkage, but also other desireable components such as a power take-off casing (11) and bearing element (12) adapted to carry ballast weight (13) and incorporatng a draft jaw (14), as near as possible to the front whell axle (2) and substantially behind the front surface of the front panelling (4) of a farm tractor, the support for all frontally disposed components is a frame (10) flange-mounted on, or integral with, the front axle bearer. The links (5) are disposed outside the panelling (4), can be swung behind the front surface of the panelling (4) into an inoperative position, are carried by a tubular rock shaft (3) which is connected to hydraulic cylinder (21), and have res­pective rear extensions (19). Each link (5) can in certain angular position, be removeably fitted by means of a journal into a the tubular rock shaft (3) and, in all other angular posi­tions, can be fixed axially by confining its rear extension (19) in a pocket (25) on the rock shaft (3) with or without limited angular float by means of a retaining bolt (30) engageable in alternative holes (23, 24). To preset the lowered position of the lower links (5), a pivotable holder (37) with laterally extending arms (38, 39) can be mounted in the jaw (14) by a bolt (36), and chains (40, 41) connected to the links (5) can be suspended by any one of their links at the end of the arms (38, 39).
