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.

A secondary spring for a rail vehicle for springing a wagon body of the rail vehicle on a chassis of the rail vehicle, the secondary spring comprising:
- a first section;
- a second section, said first and second sections divided along a predefined axis, said second section configured to be stiff orthogonally to the predefined axis and axially springy, said first section configured to be axially stiff and springy orthogonally to the predefined axis;
- and
- at least one horizontal stop disposed such that a force acting on said horizontal stop orthogonally to the predefined axis is introduced into the secondary spring between said first and said second sections.
A rail vehicle, comprising:
- at least one wagon body;
- at least one chassis;
- at least one secondary spring for springing said wagon body on said chassis, said at least one secondary spring containing:
- a first section;
- a second section, said first and second sections divided along a predefined axis, said second section configured to be stiff orthogonally to the predefined axis and axially springy, said first section configured to be axially stiff and springy orthogonally to the predefined axis;
- and
- at least one horizontal stop disposed such that a force acting on said horizontal stop orthogonally to the predefined axis is introduced into said secondary spring between said first and said second sections;
- and
- said chassis having at least one further horizontal stop configured complementary with said horizontal stop of said secondary spring.
