Abstract
Official abstract text for this publication.
A strut bearing has an upper carrier having a first outer rim and a first inner rim, the first inner rim having a first circumferential connector, and a lower carrier having a second outer rim and a second inner rim, the second inner rim having a second circumferential connector. The first inner rim is held to the second inner rim through an overlapping connection of the first circumferential connector to the second circumferential connector. The strut bearing also has a bearing arranged between the upper carrier and the lower carrier, and a first sealing ring positioned between and in contact with the first circumferential connector and the second circumferential connector. The sealing ring is formed from a material that is softer and more elastic than a material from which the first circumferential connector and the second circumferential connector are formed.
First claim
Opening claim text (preview).
What is claimed is: 1. A strut bearing, comprising an upper carrier including a first outer rim and a first inner rim, the first inner rim including a first circumferential connector; a lower carrier including a second outer rim and a second inner rim, the second inner rim including a second circumferential connector, the first inner rim being held to the second inner rim through an overlapping connection of the first circumferential connector to the second circumferential connector; a bearing arranged between the upper carrier and the lower carrier; and a first sealing ring positioned between and in contact with the first circumferential connector and the second circumferential connector, wherein the first sealing ring is formed from a material that is softer and more elastic than a material from which the first circumferential connector and the second circumferential connector are formed. 2. The strut bearing of claim 1 , wherein the first circumferential connector and the second circumferential connector are formed from nylon and the first sealing ring is formed from TPU or TPE. 3. The strut bearing of claim 1 , wherein the first circumferential connector and the second circumferential connector produce a retention force of at least 300 N. 4. The strut bearing of claim 3 , wherein the retention force is approximately 500 N. 5. The strut bearing of claim 1 , wherein the first sealing ring is integrally formed with the upper carrier or the lower carrier. 6. The strut bearing of claim 1 , wherein the first outer rim includes a second sealing ring and the second outer rim includes a seal contact portion, the second sealing ring being compressed against a surface of the seal contact portion. 7. The strut bearing of claim 6 , wherein the first sealing ring is integrally formed with the upper carrier or the lower carrier. 8. The strut bearing of claim 7 , wherein the first sealing ring and the second sealing ring are integrally formed with the upper carrier. 9. The strut bearing of claim 1 , wherein the first circumferential connector and the second circumferential connector form a snap-type connection. 10. The strut bearing of claim 9 , wherein the first circumferential connector and the second circumferential connector are hook-shaped connectors. 11. The strut bearing of claim 1 , wherein the bearing includes an upper ring supported on the upper carrier and defining an upper race, a lower ring supported on the lower carrier and defining a lower race, and rolling elements supported between the upper ring and the lower ring, the rolling elements in contact with the upper race and the lower race.
