Coupler head includes a coupler house for containing components included in a mechanical coupling and for supporting a front plate. The coupler house has two separate elongate shell-shaped house parts, which in mutually opposite and open long sides are individually joined to the outside of a beam running centrally in the coupler head and in a rear end is adapted to be coupled to a drawbar and in a front end adapted for bearing a main shaft included in the coupling, the parts being joined to the outside of the beam by welding seams running in the beam's longitudinal direction, whereby tractive forces are transferred from the coupling to the drawbar via the beam without loading the parts and seams, while thrust forces are transferred from the plate to the beam and the drawbar via the parts and seams without loading the coupling, its main shaft and the latter's bearing. |
