Automotive brake corner module
View Patent ↗A brake corner module includes a wheel bearing assembly which is configured to be coupled to the steering knuckle of the module without requiring bolts or press fit. An outer ring of the bearing assembly has a flange on one end which engages the knuckle at one end of a bore through the knuckle and a second end which is configured to be deformed to engage the second end of the knuckle bore. The wheel bearing assembly is thus captured within the bore, eliminating the need for press fit or a snap ring to retain the wheel bearing assembly.
1. A wheel bearing unit for installation within a bore of a suspension knuckle of a vehicle, comprising:
a wheel hub having a spindle extending along an axial direction of said hub;
a rolling element bearing coupled to said hub, over said spindle, and received within the bore of the suspension knuckle; and
an outer ring of said rolling element bearing having first and second engagement portions, said first engagement portion engaging the knuckle proximate a first end of the bore and said second engagement portion engaging the knuckle proximate a second end of the bore to thereby secure said outer ring within the bore.
2. The wheel bearing of claim 1 , wherein said first engagement portion of said outer ring comprises a flange extending radially outward to thereby engage the knuckle at the first end of the bore.
3. A wheel bearing unit for installation within a bore of a suspension knuckle of a vehicle, comprising:
a wheel hub having a spindle extending along an axial direction of said hub;
a rolling element bearing coupled to said hub, over said spindle, and received within the bore of the suspension knuckle; and
an outer ring of said rolling element bearing having first and second engagement portions, said first engagement portion engaging the knuckle proximate a first end of the bore and said second engagement portion engaging the knuckle proximate a second end of the bore to thereby secure said outer ring within the bore;
wherein said second engagement portion includes a deformable terminal end that initially extends along said axial direction and is subsequently deformed to engage the knuckle at the second end of the bore after said rolling element bearing is received within the bore of the knuckle.
4. A vehicle suspension corner module, comprising:
a suspension knuckle having a bore therethrough, said bore including first and second opposing ends;
a wheel bearing coupled with said knuckle, through said bore, said wheel bearing including:
a wheel hub having a spindle extending along an axial direction of said hub; and
a rolling element bearing coupled to said hub, over said spindle, and received within said bore of said knuckle, said rolling element bearing having an outer ring with first end second engagement portions, said first engagement portion engaging said knuckle proximate said first end of said bore end said second engagement portion engaging said knuckle proximate said second end of said bore to thereby secure said outer ring within said bore.
5. A vehicle suspension corner module, comprising:
a suspension knuckle having a bore therethrough, said bore including first and second opposing ends;
a wheel bearing coupled with said knuckle, through said bore, said wheel bearing including:
a wheel hub having a spindle extending alone an axial direction of said hub; and
a rolling element bearing coupled to said hub, over said spindle, and received within said bore of said knuckle, said rolling element bearing having an outer ring with first and second engagement portions, said first engagement portion engaging said knuckle proximate said first end of said bore and said second engagement portion engaging said knuckle proximate said second end of said bore to thereby secure said outer ring within said bore;
wherein said second engagement portion includes a deformable terminal end that initially extends along said axial direction and is subsequently deformed to engage said knuckle after said rolling element bearing is received within said bore of said knuckle.
6. The corner module of claim 4 , further comprising a suspension strut.
7. The corner module of claim 4 , further comprising a brake caliper assembly.
8. A method of securing a wheel bearing to a suspension knuckle, comprising the steps of:
inserting the wheel bearing within a bore of the knuckle, the wheel bearing having an outer ring with first and second engagement portions;
engaging the knuckle proximate a first end of the bore with the first engagement portion; and
deforming the second engagement portion to engage the knuckle proximate a second end of the bore to thereby secure the outer ring within the bore.
9. The method of claim 8 , wherein the first engagement portion has a flange extending in a direction radially outward of on axial direction of the bore and the step of engaging the knuckle proximate a first end of the bore includes engaging the flange against the knuckle at the first end of the bore.
10. The method of claim 8 , wherein the step of deforming the second engagement portion further comprises deforming the second engagement portion in a direction radially outward of an axial direction of the bore.
11. A method of securing a wheel bearing to a suspension knuckle, the wheel bearing having an outer ring with first and second engagement portions, the first engagement portion including a flange, the method comprising the steps of:
inserting the wheel bearing within a bore of the knuckle;
engaging the knuckle proximate a first end of the bore with the flange of the first engagement portion; and
deforming the second engagement portion in a direction radially outward of an axial direction of the bore to thereby secure the outer ring of the wheel bearing within the bore.
12. A wheel bearing unit for installation within a bore of a suspension knuckle of a vehicle, comprising:
a wheel hub having a spindle extending along an axial direction of said hub,
a rolling element bearing coupled to said hub, over said spindle, and received within the bore of the suspension knuckle; and
an outer ring of said rolling element bearing sized to be closely fit within the bore of the knuckle without interference, and having first and second engagement portions, said first engagement portion engaging the knuckle proximate a first end of the bore and said second engagement portion engaging the knuckle proximate a second end of the bore to thereby secure said outer ring within the bore.
13. A method of securing a wheel bearing to a suspension knuckle, the wheel bearing having an outer ring with first and second engagement portions, the first engagement portion including a flange, the method comprising the steps of:
closely fitting the outer ring of the wheel bearing within a bore of the knuckle without interference;
engaging the knuckle proximate a first end of the bore with the flange of the first engagement portion; and
deforming the second engagement portion in a direction radially outward of an axial direction of the bore to thereby secure the outer ring of the wheel bearing within the bore.
14. The wheel bearing unit of claim 1 , wherein at least one of said first and second engagement portions is integrally formed with said outer ring.
15. The wheel bearing unit of claim 1 , wherein said rolling element bearing is centrally located within the bore of the knuckle.
16. The wheel bearing unit of claim 3 , wherein said rolling element bearing is centrally located within the bore of the knuckle.
17. The corner module of claim 5 , wherein said rolling element bearing is centrally located within said bore of said knuckle.
18. The method of claim 8 , further comprising:
centrally locating the wheel bearing within the bore.
