Abstract

A shock absorber mounted on a vehicle includes an inner portion that is made of a metal and has a first upper end and a first lower end, and an outer portion that is made of a composite material and is integrally formed with the inner portion. The outer portion has at least one of a second upper end on which the first upper end of the inner portion is folded and a second lower end on which the first lower end of the inner portion is folded, and a middle portion that has a seat for supporting a suspension spring.

First claim

The invention claimed is:

1. A shock absorber mounted on a vehicle, comprising:
an inner portion that is made of a metal and has a first upper end and a first lower end; and
an outer portion that is made of a composite material and is integrally formed with the inner portion,
wherein the outer portion has
at least one of a second upper end on which the first upper end of the inner portion is folded and a second lower end on which the first lower end of the inner portion is folded, and
a middle portion that has a seat for supporting a suspension spring.

2. The shock absorber according to claim 1 , wherein the middle portion has a first stiffening rib combined with a lower surface of the seat.

3. The shock absorber according to claim 1 , wherein the inner portion has a first protrusion arranged under the first upper end and a second protrusion arranged over the first lower end.

4. The shock absorber according to claim 3 , wherein the inner portion has a substantially cylindrical shape and is formed by changing a cross-sectional area between the first and second protrusions.

5. The shock absorber according to claim 1 , wherein the middle portion has a fixing portion that is capable of being combined with an anti-roll bar of the front axle.

6. The shock absorber according to claim 5 , wherein a metal ring having a hole where a screw is capable of being inserted is installed in the fixing portion.

7. A front axle for a vehicle, comprising a pair of the shock absorbers according to claim 1 .

8. A vehicle having the front axle according to claim 7 .

9. The shock absorber according to claim 1 , wherein the second lower end of the outer portion has a pair of substantially parallel brackets that is capable of being combined with a steering knuckle arm of a front axle.

10. The shock absorber according to claim 9 , wherein the middle portion has a second stiffening rib combined with each of upper portions of the pair of brackets.

11. The shock absorber according to claim 9 , wherein the second lower end of the outer portion has a third stiffening rib combined with at least one of a gap between the brackets, a backside of the bracket, and an upper side of the bracket.

12. The shock absorber according to claim 9 , wherein a metal ring having a hole where a screw is capable of being inserted is installed in each of the pair of brackets.

13. The shock absorber according to claim 12 , further comprising a metal reinforcing member that surrounds a part of the second lower end of the outer portion and is capable of being installed in the bracket using at least one of the screws.
