Corrugation bellows of a transfer between two pivotably interconnected vehicles
A corrugation bellows for a transfer between two articulated vehicles has a plurality of corrugations which are generally U-shaped in cross-section. Two adjacent corrugations are connected together by a frame. The corrugations may have a web interconnecting two limbs, with the web being substantially planar in a substantially neutral state of the bellows. The limbs extend at right angles to the web in a substantially neutral state of the bellows.
1. A corrugation bellows for a transfer disposed between two pivotably interconnected vehicles, said corrugation bellows comprising:
a plurality of corrugations, each of which are generally U-shaped in cross-section, wherein two adjacent corrugations are connected together by a frame;
each of the generally U-shaped corrugations having two limbs and a web connecting the limbs; and
each of the webs being planar and the limbs extending at right angles to the web when the bellows is in a neutral state;
wherein the webs of the plurality of corrugations cooperate to provide a generally planar surface when the bellows is in a neutral state.
2. A corrugation bellows in accordance with claim 1 , wherein:
each of the limbs is substantially planar when the bellows is in a neutral state.
3. A corrugation bellows in accordance with claim 1 , wherein:
the limbs and web each have a thickness in the range of 2 to 4 millimeters.
4. A corrugation bellows in accordance with claim 1 , wherein:
the limbs and web have the same thickness.
5. A corrugation bellows in accordance with claim 1 , wherein:
the material of the web and limbs is identical.
6. A corrugation bellows in accordance with claim 1 , wherein:
the limbs and web include an elastomer material, the elastomer material being CSM or EPDM or a silicone rubber.
7. A corrugation bellows in accordance with claim 5 , wherein:
the corrugations are vulcanized.
8. A corrugation bellows in accordance with claim 1 , wherein:
the webs each remain substantially planar when the bellows is in a partially extended state.
9. A corrugation bellows for a transfer disposed between two pivotably interconnected vehicles, said corrugation bellows comprising:
a plurality of corrugations, each of which are generally U-shaped in cross-section, wherein two adjacent corrugations are connected together by a frame;
each of the generally U-shaped corrugations having two limbs and a web connecting the limbs;
each of the webs being planar and the limbs extending at right angles to the web when the bellows is in a neutral state; and
each of the corrugations having a layer of mesh material disposed in the limbs and web, the corrugations further having an elastomer material covering the layer of mesh material;
wherein the webs of the plurality of corrugations cooperate to provide a generally planar surface when the bellows is in a neutral state.
10. A corrugation bellows in accordance with claim 9 , wherein:
each of the limbs is planar when the bellows is in a substantially neutral state.
