Quick change wheel assembly

摘要

A wheel mounting assembly includes one or more nut assemblies, one for each lug stud receiving hole as provided in the wheel disc. Each nut assembly comprises a lug nut captively connected to the wheel disc by a coiled spring, with the spring configured and positioned such that the axes of the nut and disc hole remain coincident as the wheel is mounted upon the vehicle axle and the lug studs engage and axially displace the respective nuts. One spring end is affixed to the wheel disc adjacent each hole and the opposite end thereof is slidably disposed within an external recess int he nut body. In the normal at-rest condition, the spring convolutions form a coplanar spiral and maintain the captive nut flushly engaging the disc whereupon, when a lug stud enters the bottom portion of the nut and displaces it from the disc, the spring construction maintains the coincident relationship of the nut and stud axes to preclude jamming, cross-threading or stripping of the nut and stud threads during wrenching of the nuts about the studs.
