Abstract

Official abstract text for this publication.

A vehicle strut assembly includes at least a strut member, a bearing assembly, a mounting bracket and a noise isolating member. The bearing assembly encircles an upper end portion of the strut member. The mounting bracket is configured to receive the bearing assembly with mounting bracket encircling the upper end portion of the strut member and further configured to attach to a portion of a vehicle body assembly of a vehicle. The noise isolating member is installed below the mounting bracket and along a surface of the bearing assembly reducing noises transmitted from the vehicle strut assembly to the portion of the vehicle body assembly.

First claim

Opening claim text (preview).

What is claimed is: 1. A vehicle strut assembly, comprising a strut member; a bearing assembly encircling an upper end portion of the strut member; a mounting bracket configured to receive the bearing assembly with mounting bracket encircling the upper end portion of the strut member and further configured to attach to a portion of a vehicle body assembly of a vehicle; and a noise isolating member installed below the mounting bracket and along a surface of the bearing assembly reducing noises transmitted from the vehicle strut assembly to the portion of the vehicle body assembly, the noise isolating member including a first portion and a second portion, the first portion having an overall annular shape with a central opening, the second portion having an overall cylindrical shape having an inner diameter equal to an inner diameter of the first portion, the second portion extending from the first portion such that the first portion and the second portion are coaxial. 2. The vehicle strut assembly according to claim 1 , wherein the noise isolating member is installed to an upper surface of a bearing assembly and a lower surface of the mounting bracket. 3. The vehicle strut assembly according to claim 2 , wherein the noise isolating member has an annular shape with a predetermined inner diameter corresponding to an inner diameter of a portion of the lower surface of the mounting bracket. 4. The vehicle strut assembly according to claim 2 , wherein the noise isolating member an annular shape with a central opening having an inner edge that includes a plurality of radially inwardly extending projections that contact a cup-shaped portion of the mounting bracket. 5. The vehicle strut assembly according to claim 2 , wherein each of the plurality of radially inwardly extending projections of the noise isolating member has an overall rectangular shape. 6. The vehicle strut assembly according to claim 4 , wherein each of the plurality of radially inwardly extending projections of the noise isolating member has an overall triangular shape. 7. The vehicle strut assembly according to claim 1 , wherein the noise isolating member has an annular shape with a predetermined inner diameter corresponding to an inner diameter of a central portion of the lower surface of the mounting bracket. 8. The vehicle strut assembly according to claim 7 , wherein the noise isolating member defines a plurality of rectangular openings spaced apart from one another in an annular direction, each of the plurality of openings further being spaced apart from an inner radial edge and an outer radial edge of the noise isolating member. 9. The vehicle strut assembly according to claim 1 , wherein the noise isolating member has an annular shape with a central opening with an inner edge that includes a plurality of radially inwardly extending projections that contact a protruding central portion of the lower surface of the mounting bracket. 10. The vehicle strut assembly according to claim 9 , wherein each of the plurality of radially inwardly extending projections of the noise isolating member has an overall rectangular shape. 11. The vehicle strut assembly according to claim 9 , wherein each of the plurality of radially inwardly extending projections of the noise isolating member has an overall triangular shape. 12. The vehicle strut assembly according to claim 1 , wherein the noise isolating member a circular central opening and an outer edge, the outer edge having a plurality of projecting areas such that the overall shape of the outer edge corresponds to an overall shape of an outer edge of the mounting bracket. 13. The vehicle strut assembly according to claim 12 , wherein each the plurality of projecting areas of the noise isolating member has an opening that aligns with corresponding openings in the mounting bracket. 14. The vehicle strut assembly according to claim 1 , wherein the noise isolating member has an overall cylindrical shape having an inner diameter and is installed between an inner cylindrical surface of the bearing assembly and an outer cylindrical surface of the mounting bracket. 15. The vehicle strut assembly according to claim 1 , wherein the noise isolating member has an annular shape and is installed between a housing of the bearing assembly and an adjacent surface of a bearing race of the bearing assembly. 16. The vehicle strut assembly according to claim 15 , wherein the noise isolating member is coated with a lubricating material. 17. The vehicle strut assembly according to claim 16 , wherein the lubricating material is selected from one of the following materials consisting of: paraffin, grease, graphite and heavy weight oil. 18. The vehicle strut assembly according to claim 1 , wherein the noise isolating member is coated with a lubricating material. 19. The vehicle strut assembly according to claim 18 , wherein the lubricating material is selected from one of the following materials consisting of: paraffin, grease, graphite and heavy weight oil. 20. The vehicle strut assembly according to claim 1 , wherein the noise isolating member is made of at least one of: a cellulose material, a cellulose based material and a thick paper where the cellulose material is a primary material of the thick paper.
