Abstract
A bolster for a freight railway car truck relates to structural elements of freight railway car trucks. Locator recesses (8.2) with bearing surfaces (8.3) and thrust flanges (8.4) are formed in the side walls of guiding pockets (8). Wear-resistant lateral guiding plates (9) are secured within locator recesses (8.2) on the bearing surfaces (8.3), and wear-resistant inserts (10) are secured on inclined bearing seats (8.5). The use of wear-resistant lateral guiding plates (9) and wear-resistant inserts (10) protects side bearing surfaces and inclined bearing seats of guiding pockets (8) engaging with friction wedges of the shock absorber from contact wear.
