Hybrid wheel assembly with attachment pin
A wheel assembly for a vehicle includes a face portion and a rim portion. The face portion is formed from an alloy and defines a plurality of spokes extending radially outwardly between a central portion and a proximal bead element. The rim portion is formed of a composite material that defines an annular wall extending between the proximal bead element and a distal bead element. The face portion defines a mating member that is disposed in mating engagement with a rim seat defined by the rim portion. The mating member and the rim seat define a receptor for receiving a pin with said pin including shear resistors oriented to counteract shear forces F between said face portion and the rim portion.
1. A wheel assembly for a vehicle, comprising:
a face portion and a rim portion;
said face portion being formed from an alloy defining a plurality of spokes extending radially outwardly between a central portion and a proximal bead element;
said rim portion being formed of a composite material being infused with fibers and defining an annular wall and extending between said proximal bead element and a distal bead element;
said face portion defining a mating member being disposed in mating engagement with a rim seat defined by said rim portion whereby said mating member and said rim seat generate circumferential shear forces F therebetween; and
said mating member and said rim seat defining a receptor for receiving a pin with said pin including shear resistors oriented substantially perpendicular to both said fibers infused into said composite material and to the circumferential shear forces F to counteract the circumferential shear forces F generated between said mating member defined by said face portion and said rim seat defined by said rim portion.
2. The wheel assembly set forth in claim 1 , wherein said pin defines a pin axis and said shear resistors define fibrous fillers aligned with said pin axis being angularly displaced from circumferential shear forces F between said face portion and said rim portion.
3. The wheel assembly set forth in claim 2 , wherein said rim portion is adjoined to said face portion with adhesive.
4. The wheel assembly set forth in claim 3 , wherein said pin is retained in said receptor with an adhesive.
5. The wheel assembly set forth in claim 1 , wherein said receptor is sealed at one end by said face portion.
6. The wheel assembly set forth in claim 1 , wherein said rim portion includes layers of ply having elongated fibrous fillers and said fibrous fillers of each ply are disposed crosswise.
7. The wheel assembly set forth in claim 6 , wherein said fibrous fillers are disposed generally perpendicular to said shear resistors disposed in said pin.
8. The wheel assembly set forth in claim 1 , wherein said wheel assembly defines a wheel axis and said pin defines a pin axis being disposed at an acute angle to said wheel axis.
9. The wheel assembly set forth in claim 1 , wherein said wheel assembly defines low stress locations and said pin is disposed at a low stress location.
10. The wheel assembly set forth in claim 1 , wherein said wheel assembly defines tire shear force and axle shear force and said pin axis is disposed at an offset orientation to a direction of both said tire shear force and axle shear force.
11. The wheel assembly set forth in claim 1 , wherein said pin comprises a plurality of pins.
