Embodiment Construction

[0019] Referring now to the foregoing drawings, and in particular figure 1 , generally denoted by 10 a wheel hub assembly according to a preferred embodiment of the present invention. As mentioned in the preamble, the invention is applicable not only to the constructions described below, but more generally to any wheel hub assembly of a motor vehicle.

[0020] The assembly 10 comprises a first hub 20 (which is preferably but not necessarily stationary) and a second hub 31 and bearing unit 30 .

[0021] Throughout this specification and claims, terms and expressions representing positions and orientations such as "radial" and "axial" should be understood as being based on the rotation center axis X of the bearing unit 30 . Expressions such as "axially outward (outer)" and "axially inward (inward)" refer to the assembled condition and, in particular cases, preferably refer to the wheel side and the side opposite the wheel side, respectively .

[0022] The bearing unit 30 comp...

Abstract

A wheel hub assembly 10 for motor vehicles, provided with a first hub 20, which is stationary, a second hub 31, which is rotatable, and a bearing unit 30 in turn having a radially outer ring 31' provided with respective radially external raceways, at least one radially inner ring 34, 34' provided with respective radially internal raceways, at least one row of rolling bodies 32, 33, positioned between the corresponding internal and external raceways, at least one sealing device 40, 41, positioned on the axially inner side 40 with respect to the at least one row of rolling bodies 32, 33. A metaldeflector 50 configured so as to allow the water to drain and protect the area of the sealing device 40 from the external contaminant is mounted by interference on the rotating hub 31.

Description

technical field [0001] The invention relates to a wheel hub assembly provided with a new type of deflector mounted on a rotating hub for fixing the radially outer ring of a rolling bearing and having seals protecting said bearing from contamination from the external environment Functions affected by objects (water, dust, soil, etc.). [0002] The invention applies in particular, although not exclusively, to wheel hub assemblies of motor vehicles, said assemblies being provided with rolling bearings. These applications include the case where the outer ring of the bearing rotates while the inner ring of the bearing is fixed, and the opposite case where the inner ring rotates while the outer ring is fixed. Although the invention can also be used with rolling bearings in which the inner ring rotates and the outer ring is fixed, the invention is particularly advantageous in the opposite case: mounted on a rotating element integral with the outer ring that can rotate, the deflector...
