Definitions

  • the present invention relates to wheel balance weights .
  • vehicle wheels are often balanced by placing weights at selected locations .
  • One type of known weight includes a mass portion which is attached to the wheel' s rim using a spring clip . Due to high mass and low cost, such weights have been primarily made of lead in the past . For example, such weights have been made by casting molten lead around a heat-treated spring clip . As a result, a portion of the clip would be embedded inside the mass portion, whereas another portion would extend out from the mass for attachment to a wheel rim. Because of various factors , it is becoming desirable to manufacture such weights of materials other than lead. Summary of the Invention
  • the present invention provides a variety of configurations for a vehicle wheel weight .
  • Preferred embodiments utilize iron or low carbon steel for mass instead of lead as has generally been used in the past .
  • the mass is attached to the wheel using a spring clip preferably made of spring steel .
  • the spring clip includes an attachment portion secured to the mass portion by an interference fit .
  • a pocket may be formed in the mass to receive the attachment portion of the spring clip . After the attachment portion is inserted, the pocket may be closed such that the spring clip is securely retained .
  • Figure 1 is a front plan view of a vehicle wheel weight constructed in accordance with the present invention .
  • Figure 2 is a back plan view of the wheel weight of Figure 1.
  • Figure 3 is a side view of the wheel weight of Figure 1.
  • Figure 4 is a cross-sectional view along line 4-4 of Figure 1 showing the wheel weights mounted to a vehicle rim.
  • Figures 5A-5C are cross-sectional views of a mass portion in accordance with the present invention showing insertion of the spring clip in a cold-formed pocket .
  • Figure 6 is an enlarged view of the portion so indicated in Figure 5B showing an elongate groove formed in the attachment portion of the spring clip .
  • Figure 7 is a fragmentary view showing the attachment portion of an alternative spring clip having a series of spaced apart louvers formed therein .
  • Figure 8 is a cross-sectional view taken along line 8-8 of Figure 7.
  • FIGS 1 through 3 illustrate a vehicle wheel weight 10 constructed in accordance with an embodiment of the present invention .
  • wheel weight 10 includes a mass portion 12 to which a spring clip 14 is attached .
  • clip 14 (which is preferably made from spring steel ) is located in a cavity (or "pocket” ) formed in mass portion 12. This often results in a slightly raised surface 16 on the "front" of mass portion 12. (As used herein, the front of weight 10 is the side facing away from the wheel rim. )
  • mass portion 12 has an arc approximating the circumference of the rim to which it will be attached.
  • indicia is preferably provided on mass portion 12 to indicate the weight ' s mass and/or type .
  • the indicia is formed by stamping onto the mass so as to be permanent .
  • the use of such indicia on vehicle wheel weights is common, but it has previously been provided on the front . Placing indicia on the back provides a more aesthetically pleasing product because it will be hidden during use .
  • Mass portion 12 is preferably made from a nonlead material having suitable mass , such as iron or low carbon steel . Often, a 1008 steel will be especially preferred. In some cases , particularly weights of higher masses , copper may also be utilized.
  • clip 14 serves to attach weight 10 to the rim 22 of a vehicle wheel .
  • mass portion 12 is preferably configured so as to tuck neatly under the curved lip of rim 22. It can be seen that mass portion 12 has a cross-sectional profile with smooth external surfaces about its circumference . This is in contrast in many weights of the prior art which exhibited rough edges . In addition to providing a more aesthetically pleasing appearance, such a configuration tends to minimize rim damage caused by sharp surfaces .
  • mass portion 12 is desirably also configured to define a top chamfer 24 and a bottom chamfer 26.
  • Chamfers 24 and 26 are formed as relatively flat sloped surfaces extending axially along the back of mass portion 12.
  • FIG. 5A-5C illustrate one manner in which clip 14 may be attached in accordance with the present invention .
  • Figure 5A shows a cross-sectional view of mass portion 12 before installation of clip 14.
  • Mass portion 14 is preferably made from a "wire" that has been preformed with the desired cross-sectional profile .
  • chamfers 24 and 26 could be defined in the wire at the time of manufacture . A predetermined length of wire is then cut and formed with the desired arc to yield mass portion 12.
  • a pocket 30 has been formed in mass portion 12.
  • Pocket 30 is preferably cold-formed by inserting a lance having the appropriate configuration into the top of mass portion 12.
  • ⁇ Pocket 30 is preferably formed to be closed at both ends , such as by web 32 (and a similar web at the other end) .
  • a mechanically applied zinc (or other suitable coating or treatment) can be applied after the lancing step to form a protective coating on mass portion 12.
  • pocket 30 is forced closed (as indicated by arrow 38 ) after insertion of attachment portion 34.
  • clip 14 will be strongly secured to mass portion 12.
  • Figure 6 illustrates an embodiment wherein an axial groove 40 is defined across the front surface of attachment portion 34.
  • pocket 30 is closed, metal of the mass portion will flow into groove 40 to form an interference fit .
  • FIGS 7 and 8 illustrate an alternative embodiment, where a plurality of spaced apart louvers 42 are punched into attachment portion 34 of clip 14. Louvers 42 also serve to provide secure engagement between mass portion 12 and clip 14 in a manner similar to groove 40.

Abstract

La présente invention a trait à un poids de roue de véhicule comportant une portion de masse formée à froid d'un matériau ne contenant pas de plomb et d'une bride de ressort traitée thermiquement. La portion de masse présente une face avant et une face arrière, la face arrière étant adaptée à être juxtaposée contre une jante de roue. La portion de masse définit en outre une poche de fixation de bride dans laquelle une portion de fixation de la bride de ressort est introduite de sorte que la bride est fixée à la portion de masse. La bride comporte en outre une portion prolongée pour l'engagement de la jante de roue.
