Adapter coupler for adapting couplings of different design

An adapter coupler for adapting couplings of different design, wherein the adapter coupler comprises the following:

• a first connecting mechanism for a releasable connecting of the adapter coupler to a first coupling;
• a second connecting mechanism for a releasable connecting of the adapter coupler to a drawhook of a second coupling, the second connecting mechanism comprising a tension yoke with a first and a second support connectable to a tension bolt such that an accommodation is formed to receive the drawhook of the second coupling;
• a coupler housing for connecting the first connecting mechanism to the second connecting mechanism;
• and
• a mechanism for height centering which incorporates a drawbar eye connected to the coupler housing, the drawbar eye connecting to the coupler housing by means of a mechanism such that the drawbar eye can move in a longitudinal direction of the adapter coupler relative to the tension yoke for a purpose of height centering the adapter coupler,
• the mechanism comprising a drawbar which is movable in the longitudinal direction of the adapter coupler relative to the tension yoke to which an end region of the drawbar eye facing the second connecting mechanism is affixed,
• the mechanism further comprising a support connected to the coupler housing having an opening through which the drawbar is guided wherein the support is connected to the coupler housing at an upper side or a side of the coupler housing, and
• a spring element arranged between the support and the end region of the drawbar facing the first connecting mechanism to pretension the drawbar eye in a direction of said first connecting mechanism.
