Abstract

A suspension stop device provides an upper contact cap, a lower support cap and at least one bearing arranged between the caps. The upper contact cap provides a centering portion for a damper pad, inside which the pad, which is external to the device, is intended to be mounted. The centering portion extends axially inside a bore in the lower support cap.

Claims

1. A suspension stop device comprising:

an upper contact cap,

a lower support cap, and

at least one bearing arranged between the caps, wherein the upper contact cap provides a centering portion for a damper pad, inside which the pad, which is external to the device, is intended to be mounted, the centering portion extending axially inside a bore in the lower support cap.

2. The suspension stop device according to claim 1, wherein the centering portion of the upper contact cap extends axially inside a bore of an axial skirt of the lower support cap, the skirt being able to ensure the centering of a suspension spring which is external to the device.

3. The suspension stop device according to claim 1, wherein the centering portion of the upper contact cap extends axially protruding relative to a lower end rim of the lower support cap.

4. The suspension stop device according to claim 1, wherein the upper contact cap includes at least one protrusion extending radially towards the inside from a bore of the centering portion, the protrusion having a lower contact face for the damper pad.

5. The suspension stop device according to claim 1, wherein the upper contact cap includes a reinforcement suitable for reinforcing the mechanical strength of the centering portion of the cap.

6. The suspension stop device according to claim 5, wherein the reinforcement is embedded at least partly inside a body of the upper contact cap which provides the centering portion.

7. The suspension stop device according to claim 5, wherein the reinforcement is mounted radially in contact with a bore of the centering portion of the upper contact cap.

8. The suspension stop device according to claim 1, wherein the upper contact cap provides axial retention means cooperating with complementary axial retention means of the lower support cap.

9. The suspension stop device according to claim 8, wherein the retention means of the upper contact cap are arranged radially on the side opposite the centering portion of the cap relative to the bearing.

10. A suspension leg comprising:

a suspension stop device having;

an upper contact cap,

a lower support cap, and

at least one bearing arranged between the caps, wherein the upper contact cap provides a centering portion for a damper pad, inside which the pad, which is external to the device, is intended to be mounted, the centering portion extending axially inside a bore in the lower support cap, and

a contact seat in contact with an upper face of the upper contact cap of the device, and

a damper pad arranged inside the centering portion of the upper contact cap and mounted axially in contact with the contact seat.
