Abstract
A vehicle wheel weight includes a mass portion cold-formed of nonlead material adapted to be juxtaposed against a wheel rim. The mass portion defines a clip securement cavity formed therein which is seamless at its respective ends. A clip made of spring steel is also provided. The clip has an attachment portion inserted into and retained in the clip securement cavity such that an end of the attachment portion is located entirely within the mass portion and the clip is fixed to the mass portion. The clip further has an extended portion for engaging the wheel rim.
Claims12
A vehicle wheel weight comprising:
- a mass portion cold-formed of nonlead material, said mass portion adapted to be juxtaposed against a wheel rim, said mass portion defining a clip securement cavity formed therein, said clip securement cavity being seamless at the ends thereof;
- and
- a clip made of spring steel, said clip having an attachment portion inserted into and retained in said clip securement cavity such that an end of said attachment portion is located entirely within said mass portion and said clip is fixed to said mass portion, said clip further having an extended portion for engaging said wheel rim.
A method of forming a vehicle wheel weight having a mass portion and a spring clip, said method comprising steps of:
- (a) providing an elongate piece of nonlead material from which multiple mass portions will be produced;
- (b) modifying a cross section of said elongate piece through cold-forming techniques to that of said mass portions;
- (c) individually cutting said mass portions from said elongate piece;
- (d) form fitting a clip securement cavity in each said mass portion, said clip securement cavity being seamless at the ends thereof;
- (e) inserting an attachment portion of said spring clip into said mass portion such that an end of said attachment portion is located entirely within said mass portion, said spring clip further having an extended portion for engaging said wheel rim;
- and
- (f) closing said cavity against said attachment portion so as to attach said mass portion to said spring clip.
