Anti-rotation device for wheel spindle nut
First Claim
1. In combination with a wheel spindle and a spindle nut, a device for preventing rotation of the spindle nut relative to the spindle, comprising:
- a wheel spindle having a threaded end of a first diameter;
a key way formed on the threaded end;
a spindle nut having internal threads and axial grooves formed in the threads, said spindle nut threadably installable on the threaded end of the spindle for alignment of one of the grooves with the key way;
a preformed retainer having a body portion that is partially circular in configuration with an internal diameter at least equal to said first diameter to partially surround the spindle end, and a leg portion that extends normal to the body portion and configured to fit the aligned groove and key way, said retainer mountable to the spindle and spindle nut when said nut is mounted on said spindle, said retainer leg portion in engagement with said aligned groove and said key way and said body portion abutting the spindle nut and surrounding said spindle to thereby prevent rotation of said spindle nut relative to said spindle while providing easy installation and detection of the retainer.

Abstract
A retainer for preventing rotation of a spindle nut relative to a wheel spindle. The retainer engages a key way of the spindle and a groove of the spindle nut to prevent rotation of the spindle nut relative to the spindle. The retainer has a semi-circular body that surrounds the end of the spindle. The retainer has a radially inward projecting tab and an axially extending leg from the tab that engages the key way. The leg in addition to engaging the key way engages the groove of the spindle nut. The spindle nut preferably includes a recess in which the body portion of the retainer is nested.
