Abstract
A friction wedge with improved bond characteristics may include a friction wedge body and a friction wedge liner. The friction wedge body may include a pattern formed by a ridge or elevation disposed on a connecting face of the friction wedge body. The friction wedge liner may include a complementary pattern formed by a channel disposed on a bonding surface of the friction wedge liner.
Claims20
A friction wedge for use in a railway car truck assembly, the friction wedge comprising:
- a friction wedge body, the friction wedge body comprising:
- a sloped face;
- a plurality of side faces;
- a bottom face;
- and
- a connecting face defined by a connecting face perimeter, the connecting face comprising:
- a ridge disposed on the connecting face;
- and
- a connecting face pattern defined by the ridge, the connecting face pattern comprising:
- a connecting face outer pattern perimeter portion, wherein the connecting face outer pattern perimeter portion forms substantially the same shape as the connecting face perimeter, and wherein the connecting face outer pattern perimeter portion is spaced inward from the connecting face perimeter;
- a connecting face inner pattern portion;
- and
- a plurality of connecting face retention units defined by the connecting face pattern;
- and
- a friction wedge liner, the friction wedge liner comprising:
- a friction surface;
- and
- a bonding surface, the bonding surface comprising:
- a channel disposed on the bonding surface;
- and
- a bonding surface pattern defined by the channel, wherein the bonding surface pattern is configured to be complementary to the connecting face pattern to allow the channel to receive the ridge of the connecting face.
