Abstract
Official abstract text for this publication.
An air spring unit for a chassis of a motor vehicle, includes an air spring cover and an air spring piston, wherein an airtightly secured rolling bellows made of elastomer material partially delimits a working chamber between the air spring cover and the air spring piston, which working chamber can be filled with compressed air, wherein the rolling bellows is surrounded by a divided, sleeve-shaped outer guide having a first outer guide part and a second outer guide part.

The invention claimed is: 1. An air spring unit comprising: an air spring cover an air spring piston, and wherein an airtightly secured rolling bellows made of elastomer material partially delimiting a working chamber between the air spring cover and the air spring piston, which working chamber can be filled with compressed air, wherein the rolling bellows is surrounded by a divided, sleeve-shaped outer guide having a first outer guide part and a second outer guide part, the first outer guide part separate from the second outer guide part by a space, and wherein the rolling bellows forms a torsion fold in the space between the first and the second outer guide part. 2. The air spring unit as claimed in claim 1 , wherein the rolling bellows is designed as an axial bellows in the region of the torsion fold. 3. The air spring unit as claimed in claim 1 , wherein the rolling bellows is designed as a hybrid bellows having a cross ply bellows in the region of the first outer guide part and having an axial bellows in the region of the second outer guide part. 4. The air spring unit as claimed in claim 1 , wherein the first outer guide part can be secured on the rolling bellows by a first inner locking ring and/or the second outer guide part can be secured thereon by a second inner locking ring. 5. The air spring unit as claimed in claim 1 , wherein the first outer guide part and/or the second outer guide part are adhesively bonded to the rolling bellows. 6. The air spring unit as claimed in claim 1 , wherein the first outer guide part is provided on the air spring piston in a region of a first rolling fold of the rolling bellows. 7. The air spring unit as claimed in claim 1 , wherein the second outer guide part is provided on the air spring cover in a region of a second rolling fold of the rolling bellows. 8. The air spring unit as claimed in claim 1 , wherein the second outer guide part jointly surrounds a part of the air spring cover and a part of the rolling bellows. 9. The air spring unit as claimed in claim 1 , wherein the rolling bellows is secured on the air spring cover by a clamping area, wherein the second outer guide part is arranged between the clamping area and the first outer guide part. 10. The air spring unit as claimed in claim 1 , wherein the air spring unit comprises an integrated shock damper, wherein the second outer guide part remains aligned substantially parallel to the shock damper during the inward deflection of the air spring unit. 11. A chassis for a motor vehicle, comprising an air spring system, the air spring system comprising the air spring unit as claimed in claim 1 . 12. An air spring unit comprising: an air spring cover an air spring piston, and wherein an airtightly secured rolling bellows made of elastomer material partially delimiting a working chamber between the air spring cover and the air spring piston, which working chamber can be filled with compressed air, wherein the rolling bellows is surrounded by a divided, sleeve-shaped outer guide having a first outer guide part and a second outer guide part, wherein the rolling bellows forms a torsion fold between the first and the second outer guide part, wherein the rolling bellows is designed as an axial bellows in the region of the torsion fold, and wherein the rolling bellows is designed as an extended hybrid bellows having a cross ply bellows in the region of the first and the second outer guide part, wherein the rolling bellows is designed as an axial bellows in the region of the torsion fold.
