Stabilizer link for automobile suspensions
The present invention relates to a stabilizer link for automobile suspensions, comprising: a tubular body ( 1 ), having at one end a pair of first flattened areas ( 2, 2 ′) configuring a leak-tight closure of a first inner cavity ( 9 ) of the tubular body ( 1 ) located between both flattened areas ( 2, 2 ′); and a first covering ( 4 ) made of polymeric material coupled, during the forming process thereof, on the end of the tubular body ( 1 ) such that it surrounds the pair of first flattened areas ( 2, 2 ′), and wherein said covering ( 4 ) comprises a first articulation ( 6 ).
1. Stabilizer link for automobile suspensions, characterized in that it comprises:
a tubular body ( 1 ) having ends, having at one of its ends a pair of first flattened areas ( 2 , 2 ′) configuring a leak-tight closure of a first inner cavity ( 9 ) of the tubular body ( 1 ) located between both flattened areas ( 2 , 2 ′);
a first covering ( 4 ) made of polymeric material coupled, during a forming process thereof, on one of the ends of the tubular body ( 1 ) such that it surrounds the pair of first flattened areas ( 2 , 2 ′) and wherein said covering ( 4 ) comprises a first articulation ( 6 ).
2. Stabilizer link for automobile suspensions according to claim 1 , comprising a pair of second flattened areas ( 3 , 3 ′), located at the end opposite the end where the first flattened areas ( 2 , 2 ′) are placed and jointly configuring a second inner cavity ( 10 ) of the tubular body ( 1 ) and a third inner cavity ( 11 ) of the tubular body ( 1 ), arranged between the flattened areas ( 2 , 3 ), said second flattened areas ( 3 , 3 ′) being surrounded by a second covering ( 5 ) made of polymeric material that is coupled during the forming process and comprises a second articulation ( 7 ).
3. Stabilizer link for automobile suspensions according to claim 2 , wherein at least one of the coverings ( 4 , 5 ) comprises a slide bushing in which one of the articulations ( 6 , 7 ) is housed.
4. Stabilizer link for automobile suspensions according to claim 2 , comprising a flattened area ( 2 ″) located in proximity of the first flattened area ( 2 ′) and configuring a leak-tight, fourth inner cavity ( 9 ′) of the tubular body ( 1 ).
5. Stabilizer link for automobile suspensions according to claim 4 , comprising a flattened area ( 3 ″) located in proximity of the second flattened area ( 3 ′) and configuring a leak-tight fifth inner cavity ( 10 ′) of the tubular body ( 1 ).
6. Stabilizer link for automobile suspensions according to claim 5 , wherein at least one of the flattened areas ( 2 , 2 ′, 2 ″, 3 , 3 ′, 3 ″) has at least one through hole ( 2 a , 3 a ).
7. Stabilizer link for automobile suspensions according to claim 2 , wherein at least one of the ends of the tubular body ( 1 ) is shot-blasted or sand-blasted from the flattened area ( 2 , 3 ) farthest away from the end to the end of the tubular body ( 1 ).
8. Stabilizer link for automobile suspensions according to claim 2 , wherein the coverings ( 4 , 5 ) form a single body surrounding at least part of an outer surface of the tubular body ( 1 ).
9. Stabilizer link for automobile suspensions according to claim 2 , wherein the tubular body ( 1 ) has at least one perimetral groove ( 2 b , 3 b ) located in proximities of the flattened areas ( 2 , 3 ) of said tubular body ( 1 ).
10. Stabilizer link for automobile suspensions according to claim 2 , wherein the pair of first flattened areas ( 2 , 2 ′) and the pair of second flattened areas ( 3 , 3 ′) each define a flattening plane, wherein said planes are parallel to one another.
11. Stabilizer link for automobile suspensions according to claim 2 , wherein the pair of first flattened areas ( 2 , 2 ′) and the pair of second flattened areas ( 3 , 3 ′) each define a flattening plane, wherein said planes form an angle with one another.
12. Stabilizer link for automobile suspensions according to claim 2 , wherein the tubular body has free ends, and at least one free end of the tubular body ( 1 ) comprises a concave recess configured for being coupled to an articulation ( 6 , 7 ).
13. Stabilizer link for automobile suspensions according to claim 1 , wherein the tubular body has free ends, and at least one of the free ends of the tubular body ( 1 ) is open.
14. Stabilizer link for automobile suspensions according to claim 1 , wherein the tubular body ( 1 ) comprises a central cross section which is circular or polygonal.
