Abstract
A coupler for coupling a railway vehicle to another railway vehicle, comprising a mounting arm for mounting the coupler to a railway vehicle, a coupling arm, and a joint, wherein the mounting arm and the coupling arm are connected to each other via the joint in such a way that the mounting arm and the coupling arm are movable relative to each other and the coupling arm can be brought into a position ready for coupling. The coupling further comprises a protective device to prevent or reduce damage to the mounting arm and/or the coupling arm and/or the joint caused by impact forces.
Claims17
A coupler for coupling a railway vehicle to another railway vehicle, comprising:
- a mounting arm for mounting the coupler to a railway vehicle, wherein the mounting arm comprises a rear portion having a forward end and a rear end and extending along a longitudinal axis (A) from the rear end to the forward end;
- a coupling arm comprising a front portion having a forward end and a rear end, and a coupler head arranged on the forward end of the front portion;
- and
- a joint;
- wherein the mounting arm and the coupling arm are connected to each other via the joint in such a way that the mounting arm and the coupling arm are movable relative to each other and the coupling arm can be brought into a position ready for coupling;
- and
- wherein the coupler further comprises a protective device comprising a crash plate arranged on a crash plate holder, wherein the crash plate holder is arranged on a pivot anchor configured to be attached to a car of a railway vehicle, or on a part of the coupler that is non-pivotably connected to the pivot anchor to prevent or reduce damage to the mounting arm and/or the coupling arm and/or the joint caused by impact forces.

A coupler for coupling a railway vehicle to another railway vehicle, comprising:
- a mounting arm for mounting the coupler to a railway vehicle;
- a coupling arm comprising a front portion having a forward end and a rear end, and a coupler head arranged on the forward end of the front portion;
- a joint;
- wherein the mounting arm comprises a rear portion having a forward end and a rear end and extending along a longitudinal axis (A) from the rear end to the forward end;
- wherein the mounting arm and the coupling arm are connected to each other via the joint in such a way that the mounting arm and the coupling arm are movable relative to each other and the coupling arm can be brought into a position ready for coupling;
- a pivot anchor arranged on a rear end of the rear portion, the pivot anchor configured to be attached to a car of a rail vehicle;
- wherein the joint connects the rear end of the front portion to the forward end of the rear portion, the joint configured to allow the front portion to pivot in relation to the rear portion about a pivot axis (B) that is perpendicular to the longitudinal axis (A) from an operational position in which the forward portion and the rear portion are aligned so that the forward portion extends in a forward direction from the rear portion, to the pivoted position in which the forward portion is pivoted about the pivot axis (B) so that the forward portion extends at an angle from the rear portion;
- and wherein:
- the coupler further comprises a crash plate arranged on a crash plate holder, said crash plate having a substantially vertical front surface that is arranged in front of the front portion, the rear portion and the joint when the front portion is in the pivoted position;
- and
- the crash plate holder is arranged on the pivot anchor or on a part of the coupler that is non-pivotably connected to the pivot anchor.
