Abstract: A coupler head for a (Janney) coupler assembly of a multi-car rail vehicle comprises a coupler head body, a knuckle pin and a knuckle which is rotatable about the knuckle pin relative to the coupler head body between a coupled position and an uncoupled position. A first lock is configured to prevent rotation of the knuckle when the knuckle is in the coupled position. A second lock is configured to prevent rotation of the knuckle when the knuckle is in the uncoupled position. The second lock is further configured to unlock when a predetermined force, which acts on the knuckle so as to rotate the knuckle toward the coupled position, is exceeded, so that the second lock no longer hinders rotation of the knuckle toward the coupled position.

Abstract: The present invention relates to a coupler with an angular position detection assembly, the coupler (10, 10?, 10?) comprising: —a front part (11), —a rear part (12), —a rotatable joint (20) comprising a first portion (21, 23) and a second portion (22, 24), said first portion (21, 23) being rotatably attached to the second portion (22, 24), wherein the first portion (21, 23) is attached to the front part (11) and the second portion (22, 24) is attached to the rear part (12) so that the front part (11) of the coupler is rotatable in relation to the rear part (12), and the angular position detection assembly (30) comprising: —a first sensor (31) arranged in connection with one of the first portion (21, 23) and the second portion (22, 24) of the joint (20) and configured to detect or measure a parameter indicative of an angular position of the first portion (21, 23) in relation to the second portion (22, 24), —a transmitter (32) for receiving signals and transmitting them to processing circuitry (40).
