摘要:
An upper link for a utility vehicle, in particular for an agricultural tractor having a hydraulic cylinder (34) for adjusting the upper link (32) and at least one fluid tank (36), to which the hydraulic cylinder (34) can be coupled, so that in a coupled condition, hydraulic fluid limited to a pre-determined volume can be exchanged between the hydraulic cylinder (34) and the fluid tank (36), and so that a piston (40) of the hydraulic cylinder (34) can move in floating fashion by a distance (ls) corresponding to the pre-determined volume in the hydraulic cylinder (34). The present invention further includes a front-end as well as to a back-end three-point hitch of a utility vehicle with two pivotally connected lower links and an upper link with such a fluid tank.
