Abstract

A suspension assembly for a vehicle may be provided. The suspension assembly may include a strut which may operably couple a wheel of the vehicle to a body of the vehicle, a stabilizer bar, and a stabilizer bar link which may operably couple the stabilizer bar to the strut. The stabilizer bar link may include a first ball joint, a second ball joint, and a shaft which may extend therebetween. The first and second ball joints may include first and second threaded shafts, respectively, that may extend through respective first and second receiving orifices. A base of the first and second threaded shafts may include a non-rounded shaped perimeter. A perimeter of one of the first and second receiving orifices may be complementary to the non-rounded shaped perimeter to hold one of the first and second threaded shafts in place while the fastener may be tightened thereon.

Claims (43)

1. A suspension assembly for a vehicle suspension system, the assembly comprising:

a strut to operably couple a wheel of the vehicle to a body of the vehicle;

a stabilizer bar operably coupled to the strut to reduce body roll; and

a stabilizer bar link to operably couple the stabilizer bar to the strut,

wherein the stabilizer bar link comprises:

a first ball joint to operably couple the stabilizer bar link to the strut;

a second ball joint to operably couple the stabilizer bar link to the stabilizer bar; and

a shaft extending from the first ball joint to the second ball joint,

wherein the strut comprises a stabilizer bar link bracket and a first receiving orifice is formed in the stabilizer bar link bracket to operably couple to the first ball joint,

wherein a second receiving orifice is formed at an end of the stabilizer bar to operably couple to the second ball joint,

wherein the first and second ball joints comprise first and second threaded shafts, respectively, that extend through respective ones of the first and second receiving orifices and operably couple to a fastener on an opposite side of the respective ones of the first and second receiving orifices,

wherein a base of one of the first and second threaded shafts comprises a non-rounded shaped perimeter, and

wherein the non-rounded shaped perimeter of the base of one of the first and second threaded shafts is inserted into a perimeter of one of the first and second receiving orifices to hold one of the first and second threaded shafts in place while the fastener is tightened thereon.

2. The suspension assembly of claim 1 , wherein the base of the first threaded shaft comprises the non-rounded shaped perimeter and the perimeter of the first receiving orifice has a same shape as the non-rounded shaped perimeter of the base of the first threaded shaft.

3. The suspension assembly of claim 2 , wherein a length of the base of the first threaded shaft comprising the non-rounded shaped perimeter is less than a thickness of the stabilizer bar link bracket.

4. The suspension assembly of claim 2 , wherein a length of the base of the first threaded shaft comprising the non-rounded shaped perimeter is equal to a thickness of the stabilizer bar link bracket.

5. The suspension assembly of claim 1 , wherein the base of the second threaded shaft comprises the non-rounded shaped perimeter and the perimeter of the second receiving orifice has a same shape as the non-rounded shaped perimeter of the base of the second threaded shaft.

6. The suspension assembly of claim 5 , wherein a length of the base of the second threaded shaft comprising the non-rounded shaped perimeter is less than a thickness of the end of the stabilizer bar.

7. The suspension assembly of claim 5 , wherein a length of the base of the second threaded shaft comprising the non-rounded shaped perimeter is equal to a thickness of the end of the stabilizer bar.

8. The suspension assembly of claim 1 , wherein the base of the first and second threaded shafts comprises the non-rounded shaped perimeter and the perimeter of the first and second receiving orifices have a same shape as the non-rounded shaped perimeter of the base of the first and second threaded shafts, respectively.

9. The suspension assembly of claim 8 , wherein a length of the base of the first and second threaded shafts comprising the non-rounded shaped perimeter is less than or equal to a thickness of the stabilizer bar link bracket and the end of the stabilizer bar, respectively.

10. The suspension assembly of claim 1 , wherein the non-rounded shaped perimeter is hexagonal.

11. The suspension assembly of claim 1 , wherein the non-rounded shaped perimeter is triangular, square, rectangular, pentagonal, octagonal, cross shaped, x shaped, or torx shaped.

12. An upper ball joint assembly for a suspension system for a vehicle, the upper ball joint assembly comprising:

a receiving orifice operably coupled to a strut;

a ball joint having a threaded shaft to extend through the receiving orifice; and

a fastener to operably couple the threaded shaft to the receiving orifice,

wherein a base of the threaded shaft comprises a non-rounded shaped perimeter, and

wherein the non-rounded shaped perimeter of the base of the threaded shaft is inserted into a perimeter of the receiving orifice to hold the threaded shaft in place while the fastener is tightened thereon.

13. The upper ball joint assembly of claim 12 , wherein the strut comprises a stabilizer bar link bracket and the receiving orifice is formed in the stabilizer bar link bracket to operably couple to the upper ball joint assembly.

14. The upper ball joint assembly of claim 13 , wherein a length of the base of the threaded shaft comprising the non-rounded shaped perimeter is less than or equal to a thickness of the stabilizer bar link bracket.

15. The upper ball joint assembly of claim 12 , wherein the non-rounded shaped perimeter is hexagonal.

16. The upper ball joint assembly of claim 12 , wherein the non-rounded shaped perimeter is triangular, square, rectangular, pentagonal, octagonal, cross shaped, x shaped, or torx shaped.

17. A lower ball joint assembly for a suspension system for a vehicle, the lower ball joint assembly comprising:

a receiving orifice operably coupled to a stabilizer bar;

a ball joint having a threaded shaft to extend through the receiving orifice; and

a fastener to operably couple the threaded shaft to the receiving orifice,

wherein the lower ball joint assembly is operably coupled to a stabilizer bar link and to the stabilizer bar at a flattened end of the stabilizer bar,

wherein a base of the threaded shaft comprises a non-rounded shaped perimeter, and

wherein the non-rounded shaped perimeter of the base of the threaded shaft is inserted into a perimeter of the receiving orifice to hold the threaded shaft in place while the fastener is tightened thereon.

18. The lower ball joint assembly of claim 17 , wherein a length of the base of the threaded shaft comprising the non-rounded shaped perimeter is less than or equal to a thickness of the flattened end of the stabilizer bar.

19. The lower ball joint assembly of claim 17 , wherein the non-rounded shaped perimeter is hexagonal.

20. The lower ball joint assembly of claim 17 , wherein the non-rounded shaped perimeter is triangular, square, rectangular, pentagonal, octagonal, cross shaped, x shaped, or torx shaped.
