A hook coupling with a hook body (), which has a hook-in opening (), and with a closure latch () which can be adjusted between an open position and a closed position furthermore comprises: a blocking lever () which is displaceable between a blocking position, in which it blocks an adjustment of the closure latch () from the closed position towards the open position, and a release position in which it permits an adjustment of the closure latch () from the closed position towards the open position, and a triggering device () which, in its basic position, whenever blocking lever () is in the blocking position, prevents displacement of the blocking lever () into the release position, and which, when actuated out of its basic position, permits displacement of the blocking lever () into the release position. The triggering device () furthermore comprises a triggering component () which is mounted moveably on the closure latch () or preferably on the hook body () or on a component connected rigidly to the hook body () or the closure latch () and which is moveable between the basic position and a triggering position in which it permits the displacement of the blocking lever () into the release position.

Hook coupling

The invention refers to a trailer coupling () for a towing vehicle (), comprising a base body (), a coupling unit () with a coupling element (), that works with a counter-coupling element () of a trailing towing vehicle (), whereby the coupling unit () relative to the base body () is adjusted between a coupling position and a release position, and a securing device (), with a securing element (), that can be adjusted between a securing position and a release position, whereby, in its securing position, it secures the coupling unit () in its coupling position. According to the invention, the securing element (), in its release position, allows a transfer of the coupling unit () from its coupling position into its release position, and if the securing element () is pivoted by the coupling unit () in the course of its movement from the release position and into a coupling preparatory position, and then goes, when the coupling unit () has reached the coupling position, by itself into the securing position.

A tractor-trailer (,) comprises a tractor (,) and a trailer (,), a trailer coupling (,) and a supply coupling (,) between the two component vehicles (,) with a tractor-side coupling half (,) and a trailer-side coupling half (,), which can be coupled together by bringing them together along a predefined coupling axis (K). One of the coupling halves (,) is connected to the supply unit of the associated first component vehicle (,) through a flexible supply line (,). To establish the coupled state between the two coupling halves (,), an actuator (,) is arranged on the first component vehicle (,) that moves the first coupling half (,) toward the second coupling half (,) and joins the one to the other along the predefined coupling axis (K). The first coupling half (,) is arranged on the actuator (,) such that it can be oriented in all spatial directions at least within predetermined limits.

Tractor-trailer

Central guide means for the piston rod of apparatus provided with a piston reciprocating in a cylinder and comprising a piston rod centrally journaled proximate its free end between two journaling points of a guide lever, the guide lever being essentially oriented in the axial direction of the cylinder and being journaled at two journaling points on a pair of connecting rods of equal length. Fixed pivoting shafts are disposed parallel to each other and spaced equidistantly on opposite sides of a longitudinal axis of the cylinder, the pivoting shafts being coupled to the connecting rods and separated relative to the longitudinal axis of the cylinder by a distance corresponding to the distance between the journaling points of the guide lever.
