Abstract

An after-market subframe bushing support assembly that includes a RS back top bushing member formed as a disc shape with a RS back top bushing member outer diameter and a RS back top bushing member first height, and the RS back top bushing member having a center opening defined by a pair of RS back top bushing member long sides and a pair of RS back top bushing member short sides, and a RS back top bushing member second height between areas above and below the center opening and the RS back top bushing member outer diameter. The subframe bushing support assembly reduces noise-vibration-harness compared with other solutions and can easily be installed by car enthusiasts.

Claims (33)

1 . A vehicle after-market rear subframe (RS) bushing support assembly comprising:

a RS back top bushing member formed as a disc shape with a RS back top bushing member outer diameter and a RS back top bushing member first height, and the RS back top bushing member having a center opening, and a RS back top bushing member second height in a second area between areas above and below the center opening and the RS back top bushing member outer diameter; and

a RS back bottom bushing member formed as a disc shape with a RS back bottom bushing member outer diameter and a RS back bottom bushing member third height, and the RS back bottom bushing member having a center opening, and a RS back bottom bushing member fourth height in at least a portion of a bottom bushing area between areas above and below the center opening and the RS back bottom bushing member outer diameter.

2 . The vehicle after-market RS bushing support assembly of claim 1 ,

wherein the center opening of the RS back top bushing member is a substantially rectangular center opening with rounded corners; and

wherein the center opening of the RS back bottom bushing member is a substantially rectangular center opening with rounded corners.

3 . The vehicle after-market RS bushing support assembly of claim 1 ,

wherein the center opening of the RS back top bushing member is surrounded by a shape at substantially the RS back top bushing member first height with a central circle enclosed by two horizontal bars positioned above and below the central circle and is framed on a left side and a right side by curved, tapering shapes that create an hourglass-like outline, and is symmetrical along its vertical axis and horizontal axis; and

wherein the center opening of the RS back bottom bushing member is surrounded by a shape at substantially the RS back top bushing member third height with a central circle enclosed by two horizontal bars positioned above and below the central circle and is framed on a left side and a right side by curved, tapering shapes that create an hourglass-like outline, and is symmetrical along its vertical axis and horizontal axis.

4 . The vehicle after-market RS bushing support assembly of claim 1 , further comprising:

a RS front top bushing member formed as a front top two stacked disk shape, the front top two stacked disk shape comprising a front top large disk and a front top smaller disk, the front top large disk and the front top smaller disk having a stacked arrangement atop one another and forming a center opening;

a RS front bottom bushing member formed as a front bottom two stacked disk shape, the front bottom two stacked disk shape comprising a front bottom large disk and a front bottom smaller disk, the front bottom large disk and the front bottom smaller disk having a stacked arrangement atop one another and forming a center opening;

wherein the center opening of the RS front top bushing member is a surrounded by a circular design with a hollow center, surrounded by an outer ring featuring six evenly spaced, rectangular protrusions extending outward radially, each protrusion is positioned at approximately equal intervals along a circumference, giving an overall appearance of a mechanical gear; and

wherein the center opening of the RS front bottom bushing member is a surrounded by a circular design a circular design with a hollow center, surrounded by an outer ring featuring six evenly spaced, rectangular protrusions extending outward radially, each protrusion is positioned at approximately equal intervals along a circumference, giving an overall appearance of a mechanical gear.

5 . The vehicle after-market RS bushing support assembly of claim 4 , wherein a ratio of a height of the front top large disk to a height of the front top smaller disk is about 1.3 to 2.6.

6 . The vehicle after-market RS bushing support assembly of claim 4 , where a ratio between a diameter of the front top large disk and a diameter of the front top smaller disk is about 1.37.

7 . The vehicle after-market RS bushing support assembly of claim 4 , wherein an outer diameter of the front top large disk is about 3.7 inches and an outer diameter of the front top smaller disk is about 2.7 inches.

8 . The vehicle after-market RS bushing support assembly of claim 4 , wherein the front top large disk has a height of about 0.325 inches.

9 . The vehicle after-market RS bushing support assembly of claim 4 , wherein a combined height of the front top large disk and the front top small disk is about 0.575 inches.

10 . A vehicle after-market rear subframe (RS) bushing support assembly comprising:

a RS back top bushing member formed as a disc shape with a RS back top bushing member outer diameter and a RS back top bushing member first height, and the RS back top bushing member having a center opening with rounded corners, and a RS back top bushing member second height in a second area between areas above and below the center opening and the RS back top bushing member outer diameter; and

a RS back bottom bushing member formed as a disc shape with a RS back bottom bushing member outer diameter and a RS back bottom bushing member third height, and the RS back bottom bushing member having a center opening with rounded corners, and a RS back bottom bushing member fourth height in at least a portion of a bottom bushing area between areas above and below the center opening and the RS back bottom bushing member outer diameter.

11 . The vehicle after-market RS bushing support assembly of claim 10 ,

wherein the center opening of the RS back top bushing member is surrounded by a shape at substantially the RS back top bushing member first height with a central circle is enclosed by two horizontal bars positioned above and below the central circle and is framed on a left side and a right side by curved, tapering shapes that create an hourglass-like outline, and is symmetrical along its vertical axis and horizontal axis; and

wherein the center opening of the RS back bottom bushing member is surrounded by a shape at substantially the RS back bottom bushing member third height with a central circle is enclosed by two horizontal bars positioned above and below the central circle and is framed on a left side and a right side by curved, tapering shapes that create an hourglass-like outline, and is symmetrical along its vertical axis and horizontal axis.

12 . The vehicle after-market RS bushing support assembly of claim 10 , wherein the center opening with rounded corners is defined by a pair of RS back top bushing member long sides and a pair of RS back top bushing member short sides, and wherein the second area is between the RS back top bushing member short sides and the RS back top bushing member outer diameter.

13 . The vehicle after-market RS bushing support assembly of claim 10 , wherein the center opening with rounded corners is defined by a pair of RS back bottom bushing member long sides and a pair of RS back bottom bushing member short sides, and wherein the at least a portion of a bottom bushing area between a short side of the substantially rectangular center opening and the RS back bottom bushing member outer diameter is between the RS back bottom bushing member short sides and the RS back bottom bushing member outer diameter.

14 . The vehicle after-market RS bushing support assembly of claim 10 , wherein the RS back top bushing member first height, and the RS back top bushing member second height are different heights.

15 . The vehicle after-market RS bushing support assembly of claim 10 , wherein the RS back bottom bushing member third height, and the RS back bottom bushing member fourth height are different heights.

16 . A vehicle after-market rear subframe (RS) bushing support assembly comprising:
