Abstract
A suspension standard (10) for a motor vehicle has a cylindrical seat (11) for accommodating the outer, non-rotating race (13) of a wheel hub bearing (12). At least one body (16; 16′, 16″; 22) distinct from the standard (10) and the outer bearing race (13) has end portions (16a, 16b) extending in a radially outer direction on opposite sides (10a, 10b) of the standard so as to axially lock the bearing with respect to the standard.
Claims8
A bearing and suspension standard assembly for a motor vehicle wheel, comprising:
- a suspension standard (10), in particular made of aluminium,
- a bearing (12) with a non-rotating outer race (13) fixedly mounted in an essentially cylindrical seat (11) of the standard (10), and
- locking means co-operating with the outer bearing race (13) and opposite side surfaces (10a, 10b) of the standard (10) so as to axially lock the bearing with respect to the standard, wherein said locking means are formed by end portions (16a, 16b) extending in a radially outer direction from at least one body (16;
- 22) distinct from the standard (10) and the outer bearing race (13),
- characterised in that said at least one body is and fixedly secured to the outer race, and at least one of said end portions (16a, 16b) is bent against a side surface (10a, 10b) of the standard (10) by cold forming after insertion of said at least one body (16;
- 22) in said seat (11).
A bearing and suspension standard assembly for a motor vehicle wheel, comprising:
- a suspension standard (10), in particular made of aluminium,
- a bearing (12) with a non-rotating outer race (13) fixedly mounted in an essentially cylindrical seat (11) of the standard (10), and
- locking means co-operating with the bearing outer race (13) and opposite side surfaces (10a, 10b) of the standard (10) for axially locking the bearing with respect to the standard,
- characterised in that
- said locking means are formed by end portions (32b, 33b) radially outwardly extending from a pair of annular members (32, 33) in form of open rings arranged for engaging respective recesses (30, 31) formed in proximity of axially opposite edge portions (13d, 13e) of the outer race (13),
- each annular element (32, 33) has:
- a first portion (32a, 33a) protruding in an radially inner direction to engage a respective recess (30, 31) of the outer race, a second portion (32b, 33b) protruding in a radially outer direction for abutting against a respective side surface (10a, 10b) of the standard, and a third cylindrical portion (32c, 33c) joining the said first and second portions (32a, 32b;
- 33a, 33b);
- the edge portions (13d, 13e) of the outer race (13) having outer diameters smaller than the central part of the race (13), for accommodating said third portions (32c, 33c).
An assembly according to any one of the preceding claims, wherein the outer race (13) is hardened as a whole.
