Fifth wheel hitch isolation system
A fifth wheel hitch may include at least one support frame capable of engaging with a towing vehicle. The fifth wheel hitch may further include a cross-member attached to the support frame and an isolation system operatively coupled with the cross-member. The isolation system may include a beam engaged with the cross-member about a first axis, where rotation of the beam about the first axis is dampened via a cross-member isolator. The isolation system may also include a skid plate engaged with the beam about a second axis, where rotation of the skid plate about the second axis is dampened via a wing isolator.
1. A fifth wheel hitch comprising:
a cross-member;
a beam rotationally secured with said cross-member;
a skid plate rotationally secured to said beam, wherein said skid plate rotates about a transverse axis;
a dampener engaged with said beam, wherein said dampener dampens radial displacement of said skid plate along 360 degrees of said transverse axis while allowing free rotation of said skid plate about said transverse axis; and
at least one wing attached to at least one end portion of said beam wherein said dampener is attached to said wing.
2. The fifth wheel hitch of claim 1 , wherein said dampener comprises a wing isolator.
3. The fifth wheel hitch of claim 1 further comprising a fastener attaching said wing isolator to said wing wherein said skid plate rotates about said fastener.
4. The fifth wheel hitch of claim 1 further comprising at least one cross-member isolator secured to said beam about a second axis, wherein said cross-member isolator dampens rotation of said beam about said second axis.
5. A fifth wheel hitch comprising:
a pair of support frames selectively attachable to load bed of a towing vehicle;
a plurality of fastening devices configured to selectively attach said pair of support frames to said load bed of said towing vehicle
a cross-member positioned between the pair of support frames;
a beam secured with said cross-member about a first axis; and
a dampener engaged with said beam about said first axis, wherein said dampener dampens longitudinal displacement of said beam generally along said first axis.
6. The fifth wheel hitch of claim 5 , wherein said dampener comprises at least one cross-member isolator.
7. The fifth wheel hitch of claim 6 further comprising a fastener extending through at least a portion of and securing together said beam and cross-member.
8. The fifth wheel hitch of claim 7 further comprising a tube surrounding at least a portion of said fastener within said beam.
9. The fifth wheel hitch of claim 8 , wherein said tube extends through an entire width of said cross-member creating a gap into which said cross-member isolator is capable of moving.
10. The fifth wheel hitch of claim 8 , wherein said tube is welded to said cross-member dampening forces applied to said cross-member.
11. The fifth wheel hitch of claim 8 , wherein said cross-member isolator dampens shock as it is compressed axially along said fastener.
12. The fifth wheel hitch of claim 5 , further comprising a wing isolator secured to said beam, wherein said wing isolator dampens vibrations of a skid plate about a second axis.
13. A fifth wheel hitch comprising:
a pair of support frames selectively attachable to a load bed of a towing vehicle;
a plurality of fastening devices configured to selectively attach said pair of support frames to said load bed of said towing vehicle;
a pair of mounting brackets attached with the pair of support frames;
a cross-member positioned between the pair of mounting brackets;
a beam secured with said cross-member about a first axis; and
a dampener secured to said beam about said first axis, wherein said dampener dampens longitudinal displacement of said beam generally along said first axis.
14. The fifth wheel hitch of claim 13 further comprising a skid plate rotationally secured to said beam, wherein said skid plate rotates about a transverse axis.
15. The fifth wheel hitch of claim 14 further comprising a jaw mechanism operatively positioned below the skid plate.
16. The fifth wheel hitch of claim 15 further comprising a handle operatively coupled with the jaw mechanism.
17. The fifth wheel hitch of claim 14 further comprising a second dampener engaged with said beam, wherein said second dampener dampens radial displacement of said skid plate along 360 degrees of said transverse axis while allowing free rotation of said skid plate about said transverse axis.
18. The fifth wheel hitch of claim 17 , wherein the second dampener comprises rubber.
19. The fifth wheel hitch of claim 13 , wherein the dampener comprises rubber.
