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.

The invention claimed is: 1. A muff coupling in a rail-mounted vehicle coupler, for interconnecting vehicles, comprising two vehicle coupler components having ends formed with ring-shaped flanges and being interconnectable end-to-end via a muff, the muff comprising: two arch parts tightenable again
The invention claimed is: 1. A muff coupling in a rail-mounted vehicle coupler, for interconnecting vehicles, comprising two vehicle coupler components having ends formed with ring-shaped flanges and being interconnectable end-to-end via a muff, the muff comprising: two arch parts tightenable against each other, each arch part having an inner flute formed between two inwardly turned bulges, which flute is delimited by a bottom and two opposite, force-transferring side surfaces, which side surfaces are obliquely inclined or conical in order to, upon radial tightening of the arch parts against each other, be pressed against analogously obliquely inclined or conical shoulder surfaces on said flanges and thereby, by wedge action, transfer axial component forces to the same with the purpose of pressing the ends of the vehicle coupler components in close contact against each other, wherein, at least one of said vehicle coupler components, in addition to a first flange having a first shoulder surface, includes a second flange axially spaced-apart from the first flange and having a second, obliquely inclined shoulder surface, and each arch part having, in the corresponding end, a first force-transferring side surface axially spaced-apart from a second force-transferring side surface, wherein forces that directly or indirectly are transferred from the two analogously obliquely inclined side surfaces on the arch parts are distributed to both the shoulder surfaces on the vehicle coupler component in an axial train of forces near the outside of the vehicle coupler component. 2. The muff coupling according to claim 1, wherein the two force-transferring side surfaces are formed directly in the two arch parts on first and second, axially spaced-apart bulges. 3. The muff coupling according to claim 2, wherein the two flanges in a pair of flanges are located in the immediate vicinity of each other and spaced-apart by a cross-section-wise V-shaped groove. 4. The muff coupling according to claim 2, wherein the shoulder surfaces of the flanges are conical and inclined in one and the same angle (α) within the range of 10-20�� in relation to a radial plane perpendicular to a geometrical center axis (C) through the component. 5. The muff coupling according to claim 2, wherein, each one of the two vehicle coupler components includes a pair of flanges together with the appurtenant shoulder surfaces, and the arch parts at opposite ends include pairs of first and second bulges having side surfaces arranged to co-operate with said pairs of shoulder surfaces on the flanges. 6. The muff coupling according to claim 5, wherein the two flanges in a pair of flanges are located in the immediate vicinity of each other and spaced-apart by a cross-section-wise V-shaped groove. 7. The muff coupling according to claim 5, wherein the shoulder surfaces of the flanges are conical and inclined in one and the same angle (α) within the range of 10-20�� in relation to a radial plane perpendicular to a geometrical center axis (C) through the component. 8. The muff coupling according to claim 1, wherein the two force-transferring side surfaces are located on an inside of an arched distance piece on the outside of which a single external, obliquely inclined shoulder surface is formed, arranged to co-operate with a single internal side surface on the arch parts. 9. The muff coupling according to claim 8, wherein the two flanges in a pair of flanges are located in the immediate vicinity of each other and spaced-apart by a cross-section-wise V-shaped groove. 10. The muff coupling according to claim 8, wherein the shoulder surfaces of the flanges are conical and inclined in one and the same angle (α) within the range of 10-20�� in relation to a radial plane perpendicular to a geometrical center axis (C) through the component. 11. The muff coupling according to claim 1, wherein the two flanges in a pair of flanges are located in the immediate vicinity of each other and spaced-apart by a cross-section-wise V-shaped groove. 12. The muff coupling according to claim 11, wherein the shoulder surfaces of the flanges are conical and inclined in one and the same angle (α) within the range of 10-20�� in relation to a radial plane perpendicular to a geometrical center axis (C) through the component. 13. The muff coupling according to claim 1, wherein the shoulder surfaces of the flanges are conical and inclined in one and the same angle (α) within the range of 10-20�� in relation to a radial plane perpendicular to a geometrical center axis (C) through the component. 14. The muff coupling according to claim 1, further comprising a projection rising from said inner flute and cooperating with a semi-cylindrical recess formed in the end of each vehicle coupler component. 15. The muff coupling according to claim 1, wherein the two force-transferring side surfaces are formed directly in the two arch parts. 16. A muff coupling in a vehicle coupler, for interconnecting rail-mounted vehicles, that comprises two vehicle coupler components having ends formed with ring-shaped flanges and being interconnectable end-to-end via a muff, the muff comprising: two arch parts tightenable against each other, each arch part having an inner flute formed between two inwardly turned bulges, which flute is delimited by a bottom and two opposite, force-transferring side surfaces, which side surfaces are obliquely inclined or conical in order to, upon radial tightening of the arch parts against each other, be pressed against analogously obliquely inclined or conical shoulder surfaces on said flanges and thereby, by wedge action, transfer axial component forces to the same with the purpose of pressing the ends of the vehicle coupler components in close contact against each other, wherein, at least one of said vehicle coupler components, in addition to a first flange having a first shoulder surface, includes a second flange axially spaced-apart from the first flange and having a second, obliquely inclined shoulder surface, wherein forces that directly or indirectly are transferred from the two analogously obliquely inclined side surfaces on the arch parts are distributed to both the shoulder surfaces on the vehicle coupler component in an axial train of forces near the outside of the vehicle coupler component, and the two force-transferring side surfaces are formed on an inside of an arched distance piece on the outside of which piece a single external, obliquely included should surface is formed, arranged to co-operate with a single internal side surface on the arch parts. 17.
