Railway goods wagon close-coupling rod assembly, includes pivot plate with spherical bearing surfaces and resilient support to accommodate vertical and horizontal deflections

摘要

Between each end plate (4) of the coupling rod and the supportive bearing plate (5), there is a pivot plate (9). This (9) is supported by a pair of parallel spring discs on the coupling rod end . The pivot plate (9) has spherical rolling surfaces (11) facing the bearing plate (5). These permit rolling displacement of the point of longitudinal force (Ldk) transmission (14). This accommodates horizontal and vertical displacements during coupling rod deflection.
