SLIPPER END LEAF SPRING HAVING A VARIABLE CROSS SECTION

摘要

A slipper end leaf spring assembly features a main spring having opposite ends portions at which mounting members are disposed. A central portion disposed between the end portions is profiled to provide particular spring characteristics. At least one of the end portions is arranged to at least partially support a respective mounting member through contact with an upper transvers e element thereof extending across the main spring thereabove. In order to improve resistance to wear of the end portion due to contact with the upper element, the end portion has a thickness greater than a nearest end of the central portion. This shaping of the spring provides the improved resistance at the end portions without altering the spring characteristics provided by the central portion's thickness profile.
