Abstract

A stabilizer adhesive bearing for a vehicle stabilizer may comprise an annular sleeve having a resilient inner contour for coaxial arrangement on the vehicle stabilizer. The resilient inner contour of the annular sleeve may comprise on a side facing the vehicle stabilizer a three-dimensionally structured surface with an adhesive receiving volume. The three-dimensionally structured surface has a maximum roughness depth (R max ) greater than 45 μm and a core roughness depth (R K ) of at least 65% relative to the maximum roughness depth (R max ) of the three-dimensionally structured surface. The maximum roughness depth (R max ) is a total of the reduced tip height (R pk ), the core roughness depth (R K ), and the reduced groove depth (R vk ). Further, the reduced tip height (R pk ), the reduced groove depth (R vk ), and the core roughness depth (R K ) may be determined in accordance with EN ISO 13565-2: December 1997.

First claim

What is claimed is:

1. A stabilizer adhesive bearing for a vehicle stabilizer, the stabilizer adhesive bearing comprising an annular sleeve having a resilient inner contour for coaxial arrangement on the vehicle stabilizer, wherein the resilient inner contour comprises on a side facing the vehicle stabilizer a three-dimensionally structured surface with an adhesive receiving volume, wherein the three-dimensionally structured surface has a maximum roughness depth greater than 45 μm and a core roughness depth of at least 65% relative to the maximum roughness depth of the three-dimensionally structured surface, wherein the maximum roughness depth is a total of a reduced tip height, the core roughness depth, and a reduced groove depth, wherein the reduced tip height, the reduced groove depth, and the core roughness depth are determined in accordance with EN ISO 13565-2: December 1997.

2. The stabilizer adhesive bearing of claim 1 wherein the annular sleeve comprises in a longitudinal direction of the vehicle stabilizer a first sealing element that is disposed at a first end of the annular sleeve and a second sealing element that is disposed at a second end of the annular sleeve.

3. A method for forming the stabilizer adhesive bearing of claim 1 , the method comprising steps of:
(a) providing the vehicle stabilizer having a covering face for arranging the stabilizer adhesive bearing;
(b) providing the stabilizer adhesive bearing comprising the annular sleeve with the resilient inner contour on the side facing the vehicle stabilizer;
(c) providing an assembly device;
(d) providing an adhesive composition;
(e) at least partially pretreating at least one of the three-dimensionally structured surface or the covering face with the adhesive composition;
(f) positioning the stabilizer adhesive bearing in the assembly device; and
(g) positioning the vehicle stabilizer in or on the stabilizer adhesive bearing in the assembly device to produce an at least partial adhesive connection between the three-dimensionally structured surface and/or the covering face.

4. The method of claim 3 for producing a torsion rod shoulder bearing for a motor vehicle.

5. The method of claim 3 wherein a sequence of steps (e) to (f) are freely selectable.

6. The method of claim 3 wherein the positioning in step (f) is performed with pretensioning of the stabilizer adhesive bearing.

7. The method of claim 3 wherein the production of the at least partial adhesive connection in step (g) is performed in less than 120 seconds.

8. The method of claim 3 wherein the production of the at least partial adhesive connection in step (g) is performed in less than 30 seconds.

9. The method of claim 3 wherein the production of the at least partial adhesive connection in step (g) is performed without any supply of a reaction temperature.

10. The method of claim 3 comprising:
(h) removing the stabilizer adhesive bearing from the assembly device.

11. A vehicle stabilizer comprising a coaxially-arranged stabilizer adhesive bearing that comprises an annular sleeve having a resilient inner contour for coaxial arrangement on the vehicle stabilizer, wherein the resilient inner contour comprises on a side facing the vehicle stabilizer a three-dimensionally structured surface with an adhesive receiving volume, wherein the three-dimensionally structured surface has a maximum roughness depth greater than 45 μm and a core roughness depth of at least 65% relative to the maximum roughness depth of the three-dimensionally structured surface, wherein the maximum roughness depth is a total of a reduced tip height, the core roughness depth, and a reduced groove depth, wherein the reduced tip height, the reduced groove depth, and the core roughness depth are determined in accordance with EN ISO 13565-2: December 1997.

12. The vehicle stabilizer of claim 11 , wherein the vehicle stabilizer is formed by a method comprising steps of:
(a) providing the vehicle stabilizer having a covering face for arranging the stabilizer adhesive bearing;
(b) providing the stabilizer adhesive bearing comprising the annular sleeve with the resilient inner contour on the side facing the vehicle stabilizer;
(c) providing an assembly device;
(d) providing an adhesive composition;
(e) at least partially pretreating at least one of the three-dimensionally structured surface or the covering face with the adhesive composition;
(f) positioning the stabilizer adhesive bearing in the assembly device; and
(g) positioning the vehicle stabilizer in or on the stabilizer adhesive bearing in the assembly device to produce an at least partial adhesive connection between the three-dimensionally structured surface and/or the covering face.
