Abstract
In a vehicle wheel hub bearing unit and brake arrangement, the bearing forms a rotating radial flange (11) adapted for securing to a radial flange (12) of a brake member and rotate fixedly therewith. The brake member flange (12) is located substantially in the same radial plane of the bearing flange (11) and secured directly to the peripheral portion thereof. A form or splined connection (13, 14) couples the flanges (11, 12) in non-rotatable manner. The hub bearing flange (11) has a shoulder (15, 135) radially protruding from the axially inner side thereof so as to provide an axially inner abutment for the brake member flange (12). The brake member flange (12) is axially restrained from axial outward motion by the wheel rim (16, 21).
Claims12
A vehicle wheel hub bearing unit and brake arrangement, of the type in which the bearing forms a first radial flange, which is a rotating radial flange adapted for securing to a second radial flange of a brake member and rotate fixedly therewith, wherein
- a) said second radial flange is located substantially in the same radial plane of said first flange;
- b) said second flange is secured directly to a peripheral portion of said first radial flange;
- c) a form connection couples said flanges in non-rotatable manner;
- d) said first radial flange has a shoulder means radially protruding from the axially inner side thereof so as to provide an axially inner abutment for said second flange;
- e) anti-axial outward motion means are provided to axially restrain said second radial flange from axial outward motion;
- and
- f) wherein an annular yieldable spacing insert is axially interposed between the wheel and the axially outer side of the second flange.
A vehicle wheel hub bearing unit and brake arrangement, of the type in which the bearing forms a first radial flange, which is a rotating radial flange adapted for securing to a second radial flange of a brake member and rotate fixedly therewith, wherein
- a) said second radial flange is located substantially in the same radial plane of said first flange;
- b) said second flange is secured directly to a peripheral portion of said first radial flange;
- c) a form connection couples said flanges in non-rotatable manner;
- d) said first radial flange has a shoulder means radially protruding from the axially inner side thereof so as to provide an axially inner abutment for said second flange;
- e) anti-axial outward motion means are provided to axially restrain said second radial flange from axial outward motion;
- and
- f) wherein said form connection is a conical splined connection, the splines being disposed on an axial conical surfaces converging towards the outside of the vehicle.
A vehicle wheel hub bearing unit and brake arrangement, of the type in which the bearing forms a first radial flange, which is a rotating radial flange adapted for securing to a second radial flange of a brake member and rotate fixedly therewith, wherein
- a) said second radial flange is located substantially in the same radial plane of said first flange;
- b) said second flange is secured directly to a peripheral portion of said first radial flange;
- c) a form connection couples said flanges in non-rotatable manner;
- d) said first radial flange has a shoulder means radially protruding from the axially inner side thereof so as to provide an axially inner abutment for said second flange;
- e) anti-axial outward motion means are provided to axially restrain said second radial flange from axial outward motion;
- and
- f) wherein said anti-axial outward motion means are defined by elastically flexible means fitted to said second radial flange, said elastically flexible means being adapted to snap fit into a recess means obtained in the first radial flange proximate to the axially outer side thereof, so as to retain said second radial flange against said shoulder means.
A vehicle wheel hub bearing unit and brake arrangement, of the type in which the bearing forms a first radial flange, which is a rotating radial flange adapted for securing to a second radial flange of a brake member and rotate fixedly therewith, wherein
- a) said second radial flange is located substantially in the same radial plane of said first flange;
- b) said second flange is secured directly to a peripheral portion of said first radial flange;
- c) a form connection couples said flanges in non-rotatable manner;
- d) said first radial flange has a shoulder means radially protruding from the axially inner side thereof so as to provide an axially inner abutment for said second flange;
- e) anti-axial outward motion means are provided to axially restrain said second radial flange from axial outward motion;
- and
- f) wherein said anti-axial outward motion means are defined by a wheel rim.
