Abstract

A multi-width dual wheel arrangement and method utilize a dual wheel spacer and a clamping disk for selectively mounting a dual wheel having a rim to a first wheel at a desired axial spacing of the dual wheel from the first wheel along a rolling axis of the dual and first wheels. The clamping ring is positioned outboard of the rim to clamp the rim between the clamping ring and the spacer for positioning the dual wheel at a first axial spacing from the first wheel along the rolling axis. The clamping ring is positioned inboard between the rim of the dual wheel and the dual wheel spacer for positioning the dual wheel at a second axial spacing from the first wheel. A third axial spacing is provided by configuring the rim to have a convex surface that may be electively positioned facing toward or away from the first wheel.

First claim

We claim:

1. A multi-width dual wheel arrangement, for attaching a dual wheel having a rim thereof to a first wheel having a plurality of mounting bolts for mounting the first wheel for rotation about a rolling axis of the first and dual wheels, the arrangement comprising a wheel spacer, a clamping ring and a plurality of dual wheel mounting bolts, configured for selectively securing the dual wheel to the first wheel at a first and a second axial spacing of the dual wheel from the first wheel along the rolling axis, with the second axial spacing being greater than the first axial spacing:
the spacer having an axially extending body terminating at an inner end of the spacer in a first wheel bolting flange adapted for bolted engagement to the first wheel by the mounting bolts of the first wheel, the spacer also having an outer end thereof terminating in a dual wheel bolting flange;
the clamping ring being adapted for attachment by the plurality of dual wheel mounting bolts in an outboard position with the rim of the dual wheel clamped between the clamping ring and the dual wheel bolting flange of the spacer, to thereby attach the dual wheel at the first axial spacing from the first wheel along the rolling axis; and
the clamping ring being further adapted for attachment by the dual wheel mounting bolts alternatively in an inboard position between the rim of the dual wheel and the dual wheel bolting flange of the spacer, to thereby attach the dual wheel at the second axial spacing from the first wheel along the rolling axis.

2. The multi-width dual wheel spacing arrangement of claim 1 , wherein the spacer and clamping ring include piloting features for engaging and centering the rim of the dual wheel about the rolling axis.

3. The multi-width dual wheel spacing arrangement of claim 2 , wherein:
the bolting flange of the dual wheel spacer defines an outwardly axially extending male pilot for engaging and centering the rim of the dual wheel about the rolling axis when the clamping ring is disposed in the outboard position of the clamping ring, and for engaging and centering the clamping ring when the clamping ring is disposed in the inboard position of the clamping ring;
the clamping ring defines an outwardly axially extending male pilot adapted for engaging and centering the rim of the dual wheel about the rolling axis when the clamping ring is disposed in the inboard position of the clamping ring; and
the clamping ring also defines an axially inwardly extending male pilot adapted for engaging the axially outwardly extending male pilot of the spacer bolting flange, when the clamping ring is disposed in the inboard position of the clamping ring between the dual wheel rim and the dual wheel spacer, for centering the clamping ring about the rolling axis.

4. The multi-width dual wheel spacing arrangement of claim 1 , wherein:
the mounting bolts have a desired axial stretch at a specified bolting torque;
the rim of the dual wheel and the dual wheel bolting flange of the spacer have axial thicknesses thereof;
the clamping ring has an axial thickness thereof that, in combination with the axial thicknesses of the rim and the dual wheel bolting flange provide a desired alternative first axial spacing and an alternative second axial spacing of the dual wheel from the first wheel along the rolling axis; and
the axial thickness of the clamping ring is configured to provide the desired axial stretch of the mounting bolts at the specified bolting torque with the clamping ring located in either the inboard or outboard position thereof.

5. The multi-width dual wheel spacing arrangement of claim 1 , wherein the rim of the dual wheel is dished along the rolling axis to form a convex surface thereof and configured for attachment alternatively with the convex surface facing toward or away from the first wheel in such a manner that the dished shape of the rim of the dual wheel results in the dual wheel being positioned at a third axial spacing from the first wheel when the convex surface is oriented toward the first wheel.

6. The multi-width dual wheel spacing arrangement of claim 5 , wherein:
the first wheel defines a primary direction of travel of the first wheel and the dual wheel attached thereto; and
the dual wheel is configured for preferential operation in the primary direction of travel when the dual wheel is attached to the first wheel with the convex surface facing away from the first wheel.

7. The multi-width dual wheel spacing arrangement of claim 5 , wherein:
the first wheel and the dual wheel are included in a first dual wheel spacing arrangement adapted for installation on the right side of a vehicle having right and left first wheels as the right first wheel and a right dual wheel;
the right first wheel being mounted by a plurality of right first wheel mounting bolts for mounting the right first wheel for rotation about a rolling axis of the right first and right dual wheels, and the left first wheel being mounted by a plurality of right first wheel mounting bolts for mounting the right first wheel for rotation about a rolling axis of the right first and right dual wheels;
the spacer, clamping ring and plurality of dual wheel mounting bolts are respectively a first spacer, first clamping ring and a first plurality of dual wheel mounting bolts, configured for selectively securing the right dual wheel to the right first wheel at the first and second axial spacings of the right dual wheel from the right wheel along the right rolling axis, with the second axial spacing of the right dual wheel from the right first wheel being greater than the first axial spacing of the right dual wheel from the right first wheel; and
the spacing arrangement further includes a second wheel spacer, a second clamping ring and a second plurality of dual wheel mounting bolts, configured for selectively securing a left dual wheel having a rim thereof to the left first wheel at first and second axial spacings of the left dual wheel from the left first wheel along the left wheel rolling axis, with the second axial spacing of the left dual wheel from the left first wheel being greater than the first axial spacing of the left dual wheel from the left first wheel;
the second wheel spacer being identical to the first wheel spacer, having an axially extending body terminating at an inner end of the second spacer in a first wheel bolting flange adapted for bolted engagement to the left first wheel by the mounting bolts of the left first wheel, the second wheel spacer also having an outer end thereof terminating in a left dual wheel bolting flange;
the second clamping ring being identical to the first clamping ring and adapted for attachment by the left dual wheel mounting bolts in an outboard position with the rim of the left dual wheel clamped between the clamping ring and the left dual wheel bolting flange of the second wheel spacer, to thereby attach the left dual wheel at the first axial spacing from the left first wheel along the rolling axis;
the second clamping ring being further adapted for attachment by the left dual wheel mounting bolts alternatively in an inboard position between the rim of the left dual wheel and the left dual wheel bolting flange of the second wheel spacer, to thereby attach the left dual wheel at the second axial spacing from the left first wheel along the right rolling axis of the left first and dual wheels.

8. The multi-width dual wheel spacing arrangement of claim 7 , wherein the rims of the right dual wheel and left dual wheel are dished along the rolling axis to form a convex surface thereof and are configured for attachment alternatively with the convex surface facing toward or away from the first wheel in such a manner that the dished shape of the rims of
