Abstract

A wheel tread adjusting device has a flat plate provided with a plurality of holes. Two of the holes align with the jack screw bores normally present in a tapered sleeve-type hub to mount the plate to the tapered sleeve. A cut-out bore allows the plate to rest flush against the tapered sleeve without interfering with the normally present lug bolts. Two additional bores are positioned radially outside of the tapered sleeve and hold jack screws to unwedge the tapered sleeve from the hub. An adjustment rod is selectively engageable with either of two adjustment bores in the plate. Another portion of the rod can be threaded through a bracket mounted to the end of the axle, or through a lug bolt bore in the hub of an outer wheel, if dual wheels are present. The structure is extremely simple, uses the normally present bores to the maximum extent, and is made predominantly of standard available parts.

Claims13

Dependent claims

A wheel adjusting mechanism for moving a wheel axially along an axle, the wheel having a hub positioned about the axle and a tapered sleeve positioned between the hub and the axle which is axially movable relative to the hub, the sleeve fictionally holding the hub to the axle when the sleeve is wedged between the hub and the axle, and allowing the hub to move axially along the axle when the sleeve is not wedged 10 between the hub and the axle, the wheel adjusting mechanism comprising:

a. a plate having at least one adjustment bore therein;
b. mounting means for mounting said plate to the tapered sleeve of the wheel;
c. a threaded adjustment bolt substantially parallel to the axle;
d. holding means for holding one end of said adjustment bolt in said adjustment bore in said plate while allowing rotary motion of said adjustment bolt within said adjustment bore and limiting axial movement of said adjustment bolt along said adjustment bore;
e. bracket means fixed to said axle and having at least one threaded bore therein, said adjustment bolt threadedly engaging said threaded bore.
