Constant velocity joint assembly and method thereof
A joint assembly and method of utilizing the same. The joint assembly includes a first joint member drivingly connected to a second joint member by using one or more third joint members. At least a portion of a cage member is interposed between the first and second joint members. When the first joint member is plunged in a first direction, at least a portion of one or more first engagement portions of the first joint member are in direct contact with at least a portion of one or more first engagement portions of the cage member. When the first joint member is plunged in a second direction, opposite the first direction, at least a portion of one or more second engagement portions of the first joint member are in direct contact with at least a portion of one or more second engagement portions of the cage member.
1. A joint assembly, comprising:
a first joint member drivingly connected to a second joint member by one or more third joint members;
wherein said first joint member has one or more first engagement portions and one or more second engagement portions on an outer surface thereof;
wherein said one or more first engagement portions and said one or more second engagement portions of said first joint member have a substantially conical or a substantially frusto-conical shape having an outer surface that extends toward said second joint member at an angle relative to an axial centerline of said joint assembly;
a cage member having an inner surface, an outer surface, a first end, a second end, a first end portion, and a second end portion;
wherein said inner surface of said cage member has one or more first engagement portions and one or more second engagement portions;
wherein when said first joint member is plunged in a first direction at least a portion of said one or more first engagement portions of said first joint member are in direct contact with at least a portion of said one or more first engagement portions of said cage member; and wherein when said second joint member is plunged in a second direction, opposite said first direction, at least a portion of said one or more second engagement portions of said first joint member are in direct contact with at least a portion of said one or more second engagement portions of said cage member.
2. The joint assembly of claim 1 , wherein when said one or more first engagement portions of said first joint member are in direct contact with at least a portion of said one or more first engagement portions of said cage member, said first joint member has traveled a first plunging distance;
wherein when said one or more second engagement portions of said first joint member are in direct contact with at least a portion of said one or more second engagement portions of said cage member, said first joint member has traveled a second plunging distance; and wherein said first plunging distance and said second plunging distance is measured from a theoretical center of said first joint member to a theoretical center of said second joint member; and wherein said first plunging distance is greater than said second plunging distance.
3. The joint assembly of claim 2 , further comprising a first grease cover;
wherein said first grease cover has a first receiving portion having a size and shape to receive and/or retain at least a portion of said first joint member, said one or more third joint members, and/or said cage member therein when said first joint member has traveled said first plunging distance.
4. The joint assembly of claim 1 , wherein said first end portion of said inner surface of said cage member has a first substantially cylindrical portion and a first opening defining said one or more first engagement portions of said cage member; and
wherein said first substantially cylindrical portion and said first opening of said cage member have a diameter that is less than or equal to an outer diameter of said one or more first engagement portions of said first joint member.
5. The joint assembly of claim 1 , wherein said second end portion of said inner surface of said cage member has a second substantially cylindrical portion and/or a second opening defining said one or more second engagement portions of said cage member; and
wherein said second substantially cylindrical portion and/or said second opening of said cage member have a diameter that is less than or equal to an outer diameter of said one or more second engagement portions of said first joint member.
6. The joint assembly of claim 1 , wherein said first end portion of said inner surface of said cage member has a first substantially cylindrical portion and/or a first opening defining said one or more first engagement portions of said cage member;
wherein said second end portion of said inner surface of said cage member has a second substantially cylindrical portion and/or a second opening defining said one or more second engagement portions of said cage member; and
wherein said first substantially cylindrical portion and/or said first opening of said cage member have a diameter that is greater than or equal to a diameter of said second substantially cylindrical portion and/or said second opening of said cage member.
7. The joint assembly of claim 1 , wherein said one or more first or second engagement portions of said first joint member drive said cage member outward allowing said first joint member to translate outside said second joint member and absorb an amount of energy in a crash condition.
8. The joint assembly of claim 1 , wherein said one or more first engagement portions of said cage member are disposed a linear distance from said one or more second engagement portions of said cage member.
