Abstract

A headlamp adjusting mechanism having a housing member with a passage formed therethrough and an independent nut body is retained in the housing member. The independent nut body has a threaded aperture which is substantially coincident with the passage in the housing. An elongated threaded shaft extends through the passage in the housing and cooperatively engages the threaded aperture in the independent nut body. An assembly for driving the elongated shaft such as a mitered gear arrangement is operatively associated with the housing. The driving assembly transfers motion applied to the assembly to rotate the elongated shaft cooperatively engaged with the threaded aperture in the independent nut body to produce axial displacement of the elongated shaft through the passage. A friction or prevailing torque increasing device is provided on the housing for canting or forcibly angling the independent nut body to increase the frictional forces between the threaded bore in the independent nut body and the threaded surface of the shaft. The increased friction between the independent nut body and the shaft not only increases the prevailing torque, but eliminates all axial play and prevents angular deflection of the shaft. The friction increasing device is sized and dimensioned to control the degree of prevailing torque between the independent nut body and the shaft.
