Abstract
A steering mechanism for a rail vehicle includes two steering arms, each including a pair of support arms that have a joining component with a recess. The two steering arms are articulated in a manner that maintains a minimum separation between the steering arms so that the arms can rotate relative to one another. The minimum separation is maintained by an insert that installs into the joining component recesses components of each of the steering arms. The insert has two sides, each side having a flexible material and forming a shape that mates with the recess. The insert provides resistance to the rotation between the first and second steering arms, and the resistance depends on the stiffness of the flexible material of the insert.
