Abstract

A cover assembly for an air spring for vehicles includes a cover ( 1 ) and a buffer ( 2 ) in the cover ( 1 ). The cover ( 1 ) is made from plastic and has reinforcing ribs ( 3 ) on the inside. The stop buffer ( 2 ) has slots on the side thereof facing the cover ( 1 ) in a manner corresponding to the reinforcing ribs ( 3 ) of the cover ( 1 ). The ribs ( 3 ) of the cover ( 1 ) are inserted into the slots ( 8 ). Damage to the buffer ( 2 ) by impact of the ribs ( 3 ) on the buffer ( 2 ) is thus avoided.

Claims (18)

1. A cover assembly for a rolling-lobe air spring of a vehicle, the cover assembly comprising:

a cover made of plastic and having a base wall defining an outer side and an inner side;

said cover having a plurality of inwardly-directed ribs formed on said inner side of said base wall;

a stop buffer subjected to impact blows during operation of said air spring;

said stop buffer being attached to said cover and having a side facing toward said ribs; and,

said stop buffer having slot-shaped cutouts on said side thereof corresponding to said ribs with said ribs being disposed in corresponding ones of said slot-shaped cutouts so as to permit said impact blows to be transmitted directly to said base wall without causing damage to said stop buffer by said ribs.

2. The cover assembly of claim 1 , wherein said outer side of said cover has a smooth surface to prevent foreign bodies or water from collecting on said outer side during operational use of said air spring in said vehicle.

3. The cover assembly of claim 1 , wherein said stop buffer is attached to said cover with an adhesive.

4. The cover assembly of claim 1 , wherein said ribs have a predetermined height measured from said base wall; and, said slot-shaped cutouts have a depth equal to or greater than said height of said ribs.

5. The cover assembly of claim 4 , wherein said outer side of said cover has a smooth surface to prevent foreign bodies or water from collecting on said outer side during operational use of said air spring in said vehicle.

6. The cover assembly of claim 5 , wherein said stop buffer is attached to said cover with an adhesive.

7. A cover assembly for a rolling-lobe air spring of a vehicle, the cover assembly comprising:

a cover made of plastic and having a base wall defining an outer side and an inner side;

said cover having a plurality of inwardly-directed ribs formed on said inner side of said base wall;

a stop buffer subjected to impact blows during operation of said air spring;

said stop buffer being attached to said cover and having a side facing toward said ribs;

said stop buffer having slot-shaped cutouts on said side thereof corresponding to said ribs with said ribs being disposed in corresponding ones of said slot-shaped cutouts so as to permit said impact blows to be transmitted directly to said base wall without causing damage to said stop buffer by said ribs; and,

said stop buffer being made of rubber.
