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.
Claims6
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 longitudinal axis, said second section configured to be axially resilient, said first section configured to be resilient orthogonally to the longitudinal axis;
- and
- at least one horizontal stop disposed such that a force acting on said horizontal stop orthogonally to the longitudinal 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;
- and
- said chassis having at least one drive motor disposed parallel to a longitudinal axis of said chassis and said at least one further horizontal stop is disposed on said drive motor.
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 longitudinal axis, said second section configured to be rigid orthogonally to the longitudinal axis and axially resilient, said first section configured to be axially rigid and resilient orthogonally to the longitudinal axis;
- and
- at least one horizontal stop disposed such that a force acting on said horizontal stop orthogonally to the longitudinal axis is introduced into said secondary spring between said first and said second sections;
- said chassis having at least one further horizontal stop configured complementary with said horizontal stop of said secondary spring;
- and
- said chassis having at least one drive motor disposed parallel to a longitudinal axis of said chassis and said at least one further horizontal stop is disposed on said drive motor.
