The invention relates to a spring cup (1) for a primary suspension of a rail vehicle, wherein the spring cup (1) has a longitudinal axis (2) and a spring base (3) for transmitting occurring forces onto a chassis frame of the rail vehicle, comprising a spring seat (4) for receiving at least one spring element, said spring seat (4) being supported against the spring base (3) of the spring cup (1). According to the invention, in order to achieve a force transfer from the centre of the spring base (3), a central section (6) of the spring seat (4) is formed as a contact element (7) having a contact surface (8) for an emergency spring device (9), and the spring seat (4) is configured in such a way that a force acting on the contact surface (8) is introduced into the spring base (3) outside of said projection surface (10), resulting from the projection at least of the contact surface (8) along the longitudinal axis (2) onto the spring base (3). |
