Wheel bearing design
View Patent ↗A wheel bearing assembly including a modular wheel hub that can be utilized for both passive and driven wheel hub applications with the insertion of a wheel hub bore modification body. The wheel hub is rotatably mounted to a vehicle using a wheel bearing and knuckle arrangement, the wheel bearing comprising an inner ring, outer ring and rolling elements between the rings.
1. A wheel bearing arrangement comprising:
a wheel hub with an inner bore extending through said wheel hub from one axial end to an opposite end;
two rows of rolling elements for mounting the wheel hub;
said wheel hub rotatably supported by said rolling elements;
an outer ring and outer race, and an inner ring and inner race, said rolling elements being disposed between the outer race and the inner race;
a bore modification body assembled into said inner bore and providing additional rigidity to the wheel hub, whereby the wheel hub is usable as a passive wheel when the at least one bore modification body is assembled therein, and the wheel hub is usable as a driven wheel without the at least one bore modification body assembled therein.
2. The wheel bearing of claim 1 , wherein, said inner diameter of said wheel hub is modifiable to accommodate assembly of a drive member extending at least partially through said inner bore.
3. The wheel bearing of claim 2 , wherein, said inner bore is modifiable to include machining splines in a surface of said inner bore.
4. The wheel bearing of claim 1 , wherein, said bore modification body includes a solid cylindrical body, press fit into a diameter of said inner bore.
5. The wheel bearing of claim 1 , wherein, said bore modification body includes a hollow ring cylindrical body, press fit into a diameter of said inner bore.
6. A wheel bearing bore modification body comprising:
a rigidly formed substantially cylindrical body inserted into an inner bore of a wheel hub, the body providing additional rigidity to the wheel hub, whereby the wheel hub is usable as a passive wheel when the bore modification body is assembled therein, and the wheel hub is usable as a driven wheel without the bore modification body assembled therein.
7. A wheel bearing bore modification body of claim 6 , wherein, said bore modification body includes a solid cylindrical body, press fit into a diameter of said inner bore.
8. A wheel bearing bore modification body of claim 6 , wherein, said bore modification body includes a hollow ring cylindrical body, press fit into a diameter of said inner bore.
