Title:
RESILIENT MEMBER FOR RAILWAY VEHICLE SIDE BEARINGS AND METHOD OF MANUFACTURE THEREOF
Document Type and Number:
WIPO Patent Application WO2001054958
Kind Code:
A9
Abstract:
A resilient member (29) for a side bearing includes a first rigi d element (31) extending in a linear direction and having a first end and a second end. A second rigid element (41) extends in the linear direction of the first rigid element spaced from the first rigid element to provide a space between the two. The first end of the second element is displaced along the linear direction away from the first end of the first rigid element. Resilient material (39) fills the space between the first rigid element and the second rigid element with a substantially concave profile (33) connecting the first ends of the two elements. The resilient material includes at least one weakened region (37) along the substantially concave portion thereof as a result of assembly, which is located where the resilient material is subjected to the relatively lower stresses and strains when used in a side bearing.
