Abstract: A coupler for transit cars includes a coupler anchor, a coupler mechanism supported to the coupler anchor by a deformation tube and draft gear element, and a coupler support mechanism. The coupler support mechanism includes two support arms pivotally mounted to a lower part of a coupling connector. A tension rod is provided for each support arm to control the pivotal displacement of each support arm. Each support arm further includes a torsion spring which is loaded as the support arm is pivotally displaced in an upward direction and unloaded as the support arm is pivotally displaced in a downward direction. The position of each support arm may be adjusted independently, thereby allowing adjustment of the coupler along longitudinal and lateral planes of the transit car.
