Abstract
A muff coupling intended for vehicle couplers includes two components formed with ring-shaped flanges, as well as a muff consisting of at least two arch parts tightenable against each other, each having an inner flute formed between two inwardly turned bulges, which flute is delimited by obliquely inclined side surfaces to, upon radial tightening of the arch parts against each other, be pressed against analogously obliquely inclined shoulder surfaces on the flanges and thereby, by wedge action, transfer axial component forces to the same, pressing the ends of the components in close contact against each other. The arch parts are formed with double sets of bulges for cooperation with double flanges on the respective component, whereby forces that are transferred between the components via the muff are distributed to a plurality of axially spaced-apart pairs of contact surfaces in an axial train of forces near the outside of the components.
