Embodiment Construction

[0032] like figure 1 As shown, the bearing 1 comprises an inner jacket 2 , an outer jacket 3 , four wires 4 , 5 , 6 and 7 , a row of rolling elements 8 , a cage 9 and a Belleville washer 10 . The inner ring 2 comprises an axial portion 2a extending at each of its axial ends with radial portions 2b, 2c. The radial portions 2b and 2c are identical. The inner sheath 2 thus presents an annular shape with a U-shaped section.

[0033] The outer sheath 3 also has an annular shape of U-section and an axial portion 3a, a radial wall 3b and a radial wall 3c. The thickness of the radial wall 3c is smaller than the thickness of the axial portion 3a and the thickness of the radial portion 3b, and the length in the radial direction is smaller than the length of the radial portion 3b. In other words, the interval separating the radial portions 2c and 3c is larger than the interval separating the radial portions 2b and 3b.

[0034] Wires 4 and 5 are provided in the outer sheath, while wir...

Abstract

The invention relates to an antifriction bearing for a steering column. The inventive device comprises an outer ring and an inner ring, each of said rings being fitted with a raceway for rolling elements (8) which are in contact with said raceways. At least one of the rings comprises an annular casing (3) to which two wires (4, 5) are mounted which form a raceway for the rolling elements (8). Moreover, said device comprises a preload washer (10) which is mounted axially between a radial portion of the casing (3) and one of the wires. The aforementioned wire is in contact with the bore of an axial portion of the casing (3) and another wire is also in contact with the bore of said axial portion of the casing (3).

Description

technical field [0001] The present invention relates to the field of anti-wear bearings, especially for steering columns. Background technique [0002] Document FR-A-2 669 690 discloses a bearing comprising an outer ring of U-section, an inner ring of U-section, an elastic element placed in the outer ring and four treated wires, two of which are The steel wire is arranged in the inner ring, in the area of ​​connection between its axial and radial parts, while the other two are in the hole of the elastic element, and the rolling element placed in contact with the steel wire constituting the raceway of the rolling element components, such as balls. The wire is in the shape of a locating ring with its ends joined end to end when it is in place. The rolling elements can be adjacent to each other in the circumferential direction or evenly spaced from each other by means of a cage. The elastic element exhibits an annular L-section form, the axial part of which is in contact wit...
