Abstract
A secondary spring for a rail vehicle springs a wagon body of the rail vehicle on the chassis of the rail vehicle. The secondary spring is divided along a predefined axis into a first and at least one further, second section. The first section is configured to be axially stiff and springy orthogonally to the predefined axis, and the second section is configured to be stiff orthogonally to the predefined axis and axially springy. The secondary spring contains at least one horizontal stop, which is arranged on the secondary spring such that a force which acts on the horizontal stop orthogonally to the predefined axis is introduced into the secondary spring between the first and the second section.
