US 10,421,466 B2 · Spring cup for a primary suspension of a rail vehicle

Abstract

A spring cup for a primary suspension of a rail vehicle, wherein the spring cup has a longitudinal axis and a spring base for transmitting occurring forces onto a chassis frame of the rail vehicle, and includes a spring seat for receiving at least one spring element, wherein the spring seat is supported against the spring base of the spring cup, where a central section of the spring seat is formed as a contact element having a contact surface for an emergency spring device, and the spring seat is configured such that a force acting on the contact surface is introduced into the spring base outside of the projection surface, resulting from the projection at least of the contact surface along the longitudinal axis onto the spring base in order to achieve a transfer of force from the center of the spring base.
