Abstract
A wear resistant liner for use between a center plate of a body bolster and a bolster bowl of a truck bolster of a railway vehicle is provided wherein such liner comprises a polymeric laminate comprised of a first material which is adapted to reduce load concentration against a peripheral annular flange of the bolster bowl and a second material which provides an antifriction surface engaging the flange with the laminate resulting in an increased operating life for such flange.

In a railway vehicle having;
- a body provided with a body bolster and a body center plate;
- a truck provided with a truck bolster and bolster bowl defined by a truck center plate having an upstanding peripheral annular flange;
- said body center plate being received within said flange and being supported by said truck center plate and flange;
- and a wear resistant liner means disposed between said body center plate and said peripheral flange;
- the improvement wherein said liner means comprises a deformable polymeric laminate, said laminate comprising a first deformable polymeric material which is adapted to reduce load concentration against said flange and a second deformable polymeric material which provides an antifriction surface engaging said flange, said first material being an inner part of said liner means and said second material being an outer part of said liner means and a different material than said first material, said laminate resulting in an increased operating life for said flange because said laminate is adapted to deform into the contour of said flange.
In a wear resistant liner means for use between a center plate of a body bolster and a center plate of a truck bolster of a railway vehicle, said truck bolster having a bolster bowl defined by a truck center plate which has an upstanding peripheral annular flange disposed therearound, said body center plate being adapted to be received within said flange and supported by said truck center plate, the improvement wherein said liner means comprises a deformable polymeric laminate comprising a first deformable polymeric material which is adapted to reduce load concentration against said flange and a second deformable polymeric material which provides an antifriction surface engaging said flange, said first material being an inner part of said liner means and said second material being an outer part of said liner means and a different material than said first material, said laminate resulting in an increased operating life for said flange because said laminate is adapted to deform into the contour of said flange.
