Definitions
- This invention relates to rail vehicles and more particularly to a pneumatic spring for a rail vehicle.
- pneumatic springs LUF are arranged between a bogie DRE and a freight car body WKA of a rail vehicle. Such an arrangement or execution of a pneumatic spring as it is known in the state of the art is illustrated by way of example in FIG. 1 . Naturally, the spring LUF can also be filled with a gaseous medium other than air, which is why the term “pneumatic spring” in this document quite generally refers to a gas spring.
- the known pneumatic spring LUF displays an air bellow LBA arranged between two bellow rims BF 1 , BF 2 usually made of steel. Pneumatic spring LUF is connected with the freight car body WKA or with the bogie DER via the bellow rims BF 1 , BF 2 .
- an emergency spring NOT is provided, for example, a rubber layer spring between pneumatic spring LUF and the bogie, where the two bellow rims BF 1 , BF 2 are usually made in the shape of plates.
- Transversal forces occurring during operation are absorbed by the pneumatic spring LUF and the emergency spring NOT, and a transversal movement of the freight car body WKA is usually limited by transversal buffers QPU, QPU′ that cooperate with a stop ANS ( FIG. 2 ).
- transversal buffers QPU, QPU′ that cooperate with a stop ANS ( FIG. 2 ).
- known bogie designs which employ pneumatic springs LUF with sliding plates GLP for emergency operation when the pneumatic spring LUF fails, its transversal rigidity is almost completely eliminated, as a result of which the transversal travel of the freight car body WKA in the hysteresis of sliding friction is undefined.
- a pneumatic spring for a rail vehicle that comprises two bellow rims that are arranged above each other and that are connected with each other via an air bellow when in an assembled state.
- One of the bellow rims has a groove, while the other one of the bellow rims has a counterpiece for the groove for the purpose of the automatic centering in the lateral direction of the vehicle of the two bellow rims with respect to each other in case the pneumatic spring has failed.
- the groove is arranged on the bellow rim that, when in the assembled state, lies above the other bellow rim, whereby for certain pneumatic spring systems, the alignment of the groove downward can also be advantageous.
- at least one of the bellow rims can display at least one sliding element.
- the groove displays an essentially triangular or trapezoidal cross-section.
- all sliding elements are made as level surfaces, as a result of which there can develop a relatively large-surface contact between the sliding surface and the countersurface, something that has a positive effect on the service life.
- the groove and the counterpiece can essentially be designed in a congruent fashion with respect to each other.
- the groove can be bent, whereby the bend is advantageously adapted to the turnout movement.
- the counterpiece can basically have the shape of a cone, although it also can have some other shape.
- Optimized centering of the two bellow rims in case of a failure of the pneumatic spring can be achieved in the following manner:
- the apex of the groove and the counterpiece will extend essentially along a longitudinal midplane of its particular associated bellow rim. If the groove has a triangular cross-section, then sliding elements are disposed on a central portion of the facing surfaces of the upper and lower bellow rims, or one thereof, for the purpose of centering the two bellow rims in case the pneumatic spring has failed, whereas other, like sliding elements disposed on lateral portions of the facing surfaces of the upper and lower bellow rims, or one thereof, are provided to absorb vertical stresses.
- the groove on the other hand, has a trapezoidal cross-section
- sliding elements centrally on the upper and/or lower bellow rim for the purpose of absorbing vertical stresses in case the pneumatic spring has failed
- other sliding elements are provided laterally on the upper and/or lower bellow rim for the purpose of centering the two bellow rims.
- the functioning mode of the sliding plates is thus separated into a carrying row and a centering row. This separation of functions takes place as a result of the suitable choice of the tolerances and prevents the unnecessary jamming of the centering sliding plates.
- the service life is extended because the sliding elements display level sliding surfaces.
- the optimized design of the sliding plates facilitates a central air connection without which the sliding elements run over the air connection borehole, whereby the upper bellow rim, when in an assembled state, displays an air connection that is arranged centrally upon it, and the sliding elements, provided for the centering of the two bellow rims, can advantageously be made slanted on their corners that face toward the air connection, to prevent the opening from being covered up.
- the abovementioned problem is solved according to the invention also with a rail vehicle of the kind mentioned initially in that at least one pneumatic spring is arranged between the bogie and the freight car body.
- the alignment of the groove in the longitudinal direction i.e., the direction of movement) facilitates a sliding action due to the turnout motion of the bogie when moving along an arc with simultaneous maintenance of the groove centering action.
- FIGS. 1 to 3 are PRIOR ART elevation views of a rail vehicle representation showing a bogie and a freight car body of a rail vehicle with pneumatic springs;
- FIG. 4 is a basic sketch of a rail vehicle having the present invention.
- FIG. 5 is a partial top view of a bellow rim of the pneumatic spring of the present invention.
- FIG. 6 is a cross-section of the pneumatic spring of FIG. 5 ;
- FIG. 7 is a top view of the pneumatic spring of FIGS. 5 and 6 with an illustration of the possible operating states.
- FIGS. 8 to 10 each show alternate embodiments of the pneumatic spring of the present invention.
- FIGS. 4 to 10 illustrate the pneumatic spring of the present invention.
- an invention-based rail vehicle SFZ has a bogie DRE and a freight car body WAK arranged above it.
- An invention-based pneumatic spring LUF is arranged between freight car body WAK and the bogie, below which the pneumatic spring is an emergency spring NOT, for example, a rubber layer spring.
- emergency spring NOT provides for the spring suspension of the freight car body WKA in the vertical direction, while to limit the maximum lateral deflection, one can provide a centrally disposed stop ANS whose lateral deflection is limited by two transversal buffers QPU, QPU′.
- Pneumatic spring LUF displays two mutually opposite bellow rims BF 1 , BF 2 that are connected with each other via a pneumatic bellow LBA.
- Such pneumatic springs LUF or pneumatic spring systems are known to the expert in many different forms and will therefore not be explained in any greater detail at this point.
- one of the two bellow rims BF 1 has a groove NUT, which preferably has a triangular or trapezoidal cross-section—see also FIGS. 8-10 .
- the other bellow rim BF 2 displays a counterpiece GGS for the groove NUT, whereby the counterpiece GGS in a preferred embodiment of the invention is made congruent with the groove NUT.
- the counterpiece GGS is thus made as a wedge in case of a groove NUT with a triangular cross-section.
- Production can be simplified in the following manner: Bellow rim BF 2 and counterpiece GGS are made in one piece, although separate production with subsequent assembly of the counterpiece GGS and its bellow rim BF 2 would basically be possible.
- Very good centering action of the two bellow rims BF 1 , BF 2 and thus of pneumatic spring LUF in case of failure can be achieved in the following manner: Groove NUT and counterpiece GGS are so arranged on their bellow rims BF 1 , BF 2 that the apex SCH of the groove NUT and the apex SCH′ of counterpiece GGS will extend essentially along a longitudinal midplane C of its particular associated bellow rim BF 1 , BF 2 .
- the pneumatic spring fails, one can ensure good engagement of the groove NUT with its counterpiece GGS.
- groove NUT When pneumatic spring LUF is assembled, groove NUT is so arranged that the apex SCH of the groove NUT will extend essentially parallel to the longitudinal vehicle direction L.
- the groove NUT is defined on the lower bellow rim BF 2 and the counterpiece GGS is defined on the upper bellow rim BF 1 . It is essentially the geometry of the pneumatic bellows and the bellow rims that will determine whether the groove is arranged on the upper or the lower bellow rim.
- the transition phase from pneumatic operation to emergency operation represents a critical situation, where groove NUT is optimized as a result of the abovementioned wedge-shaped design for this transition.
- sliding plates GL 1 , GL 2 , GL 3 , GL 4 can be arranged on counterpiece GGS, while according to FIG. 5 , two each of sliding plates GL 1 , GL 2 , GL 3 , GL 4 can be arranged on each wedge flank, which plates cooperate with the sidewalls of groove NUT.
- the segments ABS, ABS′ that adjoin the wedge flanks can also have sliding plates GL 1 , GL 2 , whereby the vertical stresses are introduced via these sliding plates GL 1 , GL 2 , while the sliding plates GL 3 , GL 4 , arranged on the wedge flanks, will serve primarily for the purpose of centering the two bellow rims BF 1 , BF 2 with respect to each other. There is thus a functional separation of sliding plates GL 1 , GL 2 , GL 3 , GL 4 into “carrying” and “centering.”
- sliding elements GL 3 , GL 4 arranged in the middle segment, are provided to absorb vertical stresses in case pneumatic spring LUF should fail, while sliding elements GL 1 , GL 2 , arranged on a lateral segment ABS, ABS′, are provided to center the two bellow rims BF 1 , BF 2 ( FIGS. 9, 10 ).
- a compressed air supply LFA arranged centrally upon it, can include an opening OEF.
- the pneumatic air supply LFA can be arranged centrally by means of an arrangement of the sliding plates GL 3 -GL 6 upon counterpiece GGS, placed as far away from each other as possible, as a result of which, one can prevent a contact of the sliding plates GL 3 -GL 6 with the opening OEF.
- the sliding elements GL 3 , GL 4 , GL 5 , GL 6 provided for the centering of the two bellow rims BF 1 , BF 2 at their corners E 3 , E 4 , E 5 , E 6 facing toward opening OEF, can be advantageously slanted to prevent the opening OEF from being covered up ( FIGS. 5 and 7 ).
