Rail Car Components High Performance Friction wedge for locomotive brake systems
A single-piece friction wedge for use in damping relative movement between a bolster and a side frame of a railroad car truck, includes a generally horizontal bottom surface, a generally vertical front surface, and a back surface oriented at an acute primary angle with respect to the front surface.
The back surface has first and second sloped surfaces which are angled toward each other.
A damping system employing such a friction wedge includes a bolster pocket insert. The bolster pocket insert is configured to be at least partially received within a pocket of the bolster and has an inner face configured to engage the pocket of the bolster and an outer face configured to engage at least one of the first and second sloped surfaces of the back surface of the friction wedge.
