Abstract: The invention relates to a kingpin (10) for a fifth-wheel coupling of a utility vehicle, with a journal shaft (3) which extends along a centre axis (M) and has a journal head (2) at its lower end, wherein the journal shaft (3) has a fastening flange (4) at its upper end remote from the journal head (2), and with a receiving flange (5) which is placed onto the upper end of the journal shaft (3) and is fixed to the fastening flange (4). According to the invention, a measuring device for detecting driving-dynamic reaction forces is provided, wherein the measuring device is arranged in a cavity (15) which is formed in the fixed state between the receiving flange (5) and the upper end of the journal shaft (3).

Abstract: The present invention relates to an axle structure (6) for a commercial vehicle chassis having a wheel axle (R), the spatial position of which is determined by axes of rotation of at least two wheels (16) arranged on opposite sides of the axle structure (6). In order to create an axle construction (6) that leaves sufficient installation space to provide the commercial vehicle (2) with an electric drive in the area of the axle construction (6) and that nevertheless enables safe driving behaviour and a high level of driving comfort, according to the invention the steering arms (8) on the side of the wheel axle (R) facing away from the pivot bearings (10) are connected to one another via an axle bridge (22) and a fastening bracket (24) for connecting steering rods (26) is formed in the centre area of the axle bridge (22).

Abstract: The invention relates to a lane guidance system (10) for guiding and stabilising a vehicle axle along a lane, comprising a Watt linkage arrangement for connecting, in relatively movable manner, the vehicle axle to an underside (x) of a chassis, wherein the Watt linkage arrangement has at least two Watt linkages (20) which correspond in their guide direction (F) and are arranged in the transverse direction (Q), wherein the Watt linkage arrangement has a guide element (30) for guiding the vehicle axle along a straight line in the guide direction (F). According to the invention, the Watt linkages (20) are fastened, by means of their longitudinal ends (22, 24), to the guide element (30) and to the chassis, wherein the guided vehicle axle is a trailer axle (A) of a semitrailer.
