Abstract
A vehicle wheel cover assembly is provided comprising a vehicle wheel mounted on a plurality of circumferentially spaced lug studs with lug stud nuts. A wheel cover overlaying the vehicle wheel is formed with a plurality of circumferentially spaced openings through each of which spaced openings extends the end of a corresponding lug studs. Wheel cover retainer nuts engage the lug studs to secure the wheel cover to the wheel.
Claims9
A vehicle wheel assembly comprising:
- a wheel having a rim portion and a spider portion, said spider portion having a central mounting portion and a peripheral rim engaging portion, said mounting portion defining a central hub receiving opening and a plurality of circumferentially spaced lug stud receiving openings arranged radially outwardly from said central opening;
- a plurality of lug studs extending, one each, through a corresponding one of said lug stud receiving openings of said wheel;
- a plurality of lug stud nuts engaging, one each, a corresponding one of said lug studs for operatively securing said wheel to the vehicle;
- a wheel cover overlaying at least a central area of said spider portion, being formed with a plurality of circumferentially spaced openings, each of which is aligned with one of said lug stud receiving openings of said spider portion and through each of which spaced openings extends an end portion of a corresponding one of a plurality of said lug studs extending beyond its corresponding lug stud nut;
- and
- a plurality of wheel cover retainer nuts engaging, one each, a corresponding lug stud end portion, operatively securing said wheel cover to the wheel, each of said retainer nuts having (i) a polyhedral exterior surface portion with a longitudinal axis substantially parallel to that of the wheel, which polyhedral exterior surface portion is frustro-conical to limit lug wrench torque applicable thereto, and (ii) a knurled exterior surface portion outward of said polyhedral exterior surface portion.

- a wheel having a rim portion and a spider portion, said spider portion having a central mounting portion and a peripheral rim engaging portion, said mounting portion defining a central hub receiving opening and a plurality of circumferentially spaced lug stud receiving openings arranged radially outwardly from said central opening;
- a plurality of lug studs extending, one each, through a corresponding one of said lug stud receiving openings of said wheel;
- a plurality of lug stud nuts engaging, one each, a corresponding one of said lug studs for operatively securing said wheel to the vehicle;
- a wheel cover overlaying at least a central area of said spider portion, being formed with axially inward extending wells, each having a well bottom wall, and with a plurality of circumferentially spaced openings located, one each, in a corresponding well bottom wall, each of said spaced openings being aligned with one of said lug stud receiving openings of said spider portion, an end portion of a corresponding one of said lug studs extending beyond its corresponding lug stud nut through a corresponding one of said spaced openings, wherein a radially extending portion of the outboard surface of the wheel cover immediately peripheral to each of the said spaced openings is serrated;
- and
- a plurality of plastic wheel cover retainer nuts, each being disposed within a corresponding one of said wells and engaging, one each, a corresponding lug stud end portion for operatively securing said wheel cover to the wheel, each said retainer nut being closed-ended at its axially outer end and having:
- (i) a frusto-conical extension extending axially inward into a corresponding one of said circumferentially spaced openings of said wheel cover, said extension being of smaller diameter at is axially inward end and being substantially in contact with an axially extending annular surface of said corresponding one of said circumferentially spaced openings of said wheel cover;
- (ii) a portion of its exterior surface formed as a frusto-conical polyhedron to limit lug wrench torque applicable thereto with a longitudinal axis substantially parallel to that of the wheel, wherein a radially extending, axially outward facing surface of each of said lug stud nuts has substantial surface contact with a corresponding, radially extending, axially inward facing surface portion of said wheel cover, said wheel cover being sandwiched between said lug stud nuts and said retainer nuts;
- and
- (iii) a radially extending, axially inward facing serrated surface engaging a corresponding serrated portion of said outboard surface of the wheel cover.
