Removable spindle axle sealing mechanism
View Patent ↗A removable spindle axle improvement using a cap attached to a rim formed along an inside surface of a torsion arm, wherein the cap seals a threaded fastener. The rim used for attachment can be a groove, collar, or a collared washer. In an alternative embodiment, a first O-ring is positioned along an end of a spindle axle tapered body and a second O-ring groove is positioned along an opposite end of the spindle axle tapered body to hermetically seal an area of the spindle axle therebetween. In a further embodiment, a first O-ring is positioned along one end of a spindle axle socket and a second O-ring is positioned along a second end of the spindle axle socket to hermetically seal an area of the spindle axle therebetween.
1. A removable spindle axle assembly defined by a torsion arm having an inside surface and an outside surface defining a tapered open-ended spindle axle socket therebetween; a spindle axle having a proximal end and a distal end, said proximal end including a tapered body for mounting in said spindle axle socket of said torsion arm such that said proximal end extends through said spindle axle socket to said inside surface; a threaded fastener tightened to said proximal end, securing said spindle axle to said torsion arm; and a hub assembly securable to said distal end of said spindle axle, the improvement comprising: a first O-ring groove formed along a proximal end of said tapered body for receipt of a first O-ring, and a second O-ring groove formed along a distal end of said tapered body for receipt of a second O-ring; wherein said first and second O-rings hermetically seal an area of said spindle axle therebetween when said spindle axle is attached to said torsion arm body.
2. The removable spindle axle assembly according to claim 1 including a cap constructed and arranged to attached to a rim formed along an inside surface of said torsion arm, wherein said cap seals said threaded fastener from exposure to all environmental elements.
3. The removable spindle axle assembly according to claim 2 wherein said rim is a groove formed in said torsion arm around said threaded fastener.
4. The removable spindle axle assembly according to claim 2 wherein said rim is a collar formed in said torsion arm around said threaded fastener.
5. The removable spindle axle assembly according to claim 2 wherein said rim formed on a collared washer positioned between said threaded fastener and said housing, said collared washer defined as a circular plate with a raised rim around an outer diameter and a centrally disposed aperture sized to receive said proximal end of said spindle axle.
6. A removable spindle axle assembly defined by a torsion arm having an inside surface and an outside surface defining a tapered open-ended spindle axle socket therebetween; said spindle axle having a proximal end and a distal end, said proximal end including a tapered body for mounting in said spindle axle socket of said torsion arm such that said proximal end extends through said spindle axle socket to the inside surface; a threaded fastener tightened to said proximal end, securing said spindle axle to said torsion arm; and a hub assembly securable to said distal end of said spindle axle, the improvement comprising: a first O-ring groove formed along a proximal end of said spindle axle socket for receipt of said first O-ring, and a second O-ring groove formed along a distal end of said spindle axle socket for receipt of said second O-ring; wherein said first and second O-rings hermetically seal an area of said spindle axle therebetween when said spindle axle is attached to said torsion arm body.
7. The removable spindle axle assembly according to claim 6 including a cap constructed and arranged to attached to a rim formed along an inside surface of said torsion arm wherein said cap seals said threaded fastener from exposure to all environmental elements.
8. The removable spindle axle assembly according to claim 7 wherein said rim is a groove formed in said torsion arm around said threaded fastener.
9. The removable spindle axle assembly according to claim 7 wherein said rim is a collar formed in said torsion arm around said threaded fastener.
10. The removable spindle axle assembly according to claim 7 wherein said rim formed on a collared washer positioned between said threaded fastener and said housing, said collared washer defined as a circular plate with a raised rim around an outer diameter and a centrally disposed aperture sized to receive said proximal end of said spindle axle.
