- ABSTRACT [52] 11.8. C1 280/421, 174/86, 280/422 511 Km. (:1 B60111 1/08 A means for extending wires through the center pivot [58] 11 18111 011 Search 174/86; 280/421, of an articulated vehicle including an inner sleeve and 230/422 an outer sleeve with a pair of bushings trapped therebetween to permit a bundle of wires to extend there- [56] R f enc Cit d through whereby the life of the wires is enhanced.
- This invention relates to articulated vehicles and more particularly to a structural arrangement for extending electrical wires through the pivot connection between the units comprising the articulated vehicle.
- the extending of electrical wires between the units comprising an articulated vehicle has always constituted a problem because of the bending stresses to which the wires are subjected. This problem is created when the wires are extended across the pivot axis such that as the vehicle runs through its cycles the wires are repeatedly bent causing metal fatigue and subsequent breakage thereof.
- Another object of this invention is to provide an electrical harness which is positioned such that the wires are hanging in a plane directly over or under the pivot axis of the vehicle.
- Yet another object of this invention is to provide a structural arrangement for stringing electrical wires whereby the wires hang freely in the same plane as that struck out by the pivot means.
- Still another object of this invention is to provide a method for stringing wires between the units of an articulated vehicle whereby the wires are subjected to torsional and not bending forces.
- FIGURE is a side sectional view of a preferred form of the wire arrangement according to the present invention showing the wires vertically orientated.
- Wire means 10 enters box or enclosure means 12 from a pipe or conduit means 14 which enters via aperture l6.
- Wire means 10 passes vertically through aperture means 18, coupling or bushing means 20, aperture means 22, into lower box or enclosure means 24 from which it passes into lower pipe or conduit means 26.
- the bushing means includes: an inner sleeve means 30 welded or otherwise suitably fixed to bottom means 32 of top enclosure means 12, extending downwardly through aperture means 18 and 22, pivotally into lower enclosure means 24; an outer collar means 34 carrying sleeve means 30 therein and being fixed to the top 36 of lower enclosure means 38 and extending upwardly to a point almost abutting bottom means 40 of enclosure 12; and two spaced apart polytetrafluoroethylene (sold under the trademark Teflon owned by E. I. Du Pont de Nemours, and Company) washers 42 and 44 sandwiched between sleeve means 30 and collar means 34.
- Teflon polytetrafluoroethylene
- the line 46 shown in FIG. 1 passes through the center of the vertical portion 48 of wire means 10 as well as the center of the pivot point of the articulated vehicle (not shown).
- the wire means 10 is subjected to only torsional stresses as articulated vehicle pivots about line 46. It is apparent that as vertical portion 48 is moved away from the line 46 the forces acting thereupon would tend to become more of a bending nature and less of a torsional nature. It is thus apparent that the vertical portion 48 of the wire means 10 must be located directly on a line passing through the center of the pivot point of the articulated vehicle.
- an excess of wire means 10 is employed for the stringing between the units of the articulated vehicle such that a smooth bend 50 is formed in the upper enclosure means 12. This tends to avoid any possibility of wear damage as the wire means 10 passes over the tip 62 of pipe means 14.
- the wire bundle means It is tied or otherwise confined by a first and second securing means 54 and 56 located in the bend portions 50 and 60.
- a first and second securing means 54 and 56 located in the bend portions 50 and 60.
- the wire means 10 torques about its vertical axis and is subjected to forces described by the formula: S TC/J wherein: S is the torsional stress in lbs/sq. in., J is the polar moment ofinertia of the wire, C is the distance from the neutral axis to the extreme of the fiber, and Tis the torque in inch pounds.
- S is the torsional stress in lbs/sq. in.
- J is the polar moment ofinertia of the wire
- C is the distance from the neutral axis to the extreme of the fiber
- Tis the torque in inch pounds As was stated previously, the bending forces are to be avoided, such forces being described by the formula: 8,, MC/I wherein: S is the bending stress in lbs./sq.in., M is the moment thereof in inch pounds, C is the distance from the neutral axis to the extreme of the fiber, and B is the moment of inertia of a section about an axis passing through the center of gravity.
- said sleeve and collar being arranged to be coaxial with said pivot axis of said frame sections;
