Description

The wheel balance weight that is used for automobile tire

Technical field

The present invention relates to a kind of mode with bonding and be installed in the balancing weight that is used for automobile tire on the wheel, especially, corresponding to the variation of the wheel internal diameter under the various criterion, this wheel balance weight that is used for automobile tire is easy to bending and extension.

Background technique

Usually use prefabricated molds to make automobile tire through sulfidation.In the process that forms tire, lose the weight balancing of tire probably, just, produce the skewness of tire weight inevitably.When tyre rotation,, the imbalance of this tire weight reduces the comfortable of vehicle ride thereby causing the vibrations on chassis.And excessive or endurance longly also can be continuously applied fatigue on the chassis when this vibrations; Simultaneously, thereby can occur the stability reduction that the slit causes motor live time to reduce and drives between the each several part, therefore increase the possibility of security incident.

For addressing the above problem, a kind of equilibrate counterweight with suitable weight is installed on the even point of wheel, all should put the imbalance of compensation tire at this, thereby keeps the weight distribution of tire equably.

More specifically, automobile tire be installed in around the wheel of axletree coupling and inflation be tubeless shape.At this moment, balancing weight can be installed in the suitable position of wheel inner edge, and tire surrounds described wheel, therefore compensates the imbalance of tire weight.

This balancing weight is made by the relatively large lead of proportion usually.Yet this balancing weight of being made by lead causes environmental pollution problem easily.For above-mentioned reasons, use manufacture of materials balancing weights such as mild steel and selling in recent years.

In process of production, traditional balancing weight of being made by lead is by the method production and the assembling of clamping or bonding.On the other hand, for preventing the pollution of the environment, and consider the design modification and the outward appearance of tire, and since the demand of scorch that the automobile high-performance is brought and stability mainly install by the balancing weight that mild steel is made by adhesive method.

As depicted in figs. 1 and 2, the balancing weight 2 by mild steel is made is installed in along the suitable position of wheel 1 inner edge by adhesive method, and this balancing weight is strip and has preset thickness and length.Balancing weight 2, is bonded on the wheel 1 as two-sided tape by using bonding piece 3.Yet this bonding mode needs balancing weight 2 to satisfy to have the condition of the inner edge radius of curvature identical with wheel 1; That is to say that if balancing weight 2 can not closely insert the inner edge of wheel 1, cohesive force can weaken and installment state also can be unstable, thereby reduces reliability.

Up to the present, with above-mentioned bonding mode balancing weight 2 being installed has improved in many ways and has been employed.A kind of such known technology is that Japan Patent discloses H11-257437 number.Specifically, above-mentionedly come out with the main body that a kind of balancing weight comprises the sticking patch type, it is bar shaped and has predetermined thickness, length, width and weight.Aforementioned body is included in the bonding piece of its one side and a plurality of " V " the type groove (seam) of its another side, should use rolling mill or punching machine on perpendicular to this main body longitudinal direction, to form by " V " type groove (seam) with extrusion process, wherein, described groove equally spaced forms on the width of entire body.Simultaneously, described groove changes so that the brittleness of groove to be provided cross sectional area suddenly, and like this, balancing weight can partly crooked in one direction and extension when being subjected to respect to the external force on the longitudinal direction of each groove.

Yet, in different metallic characters, have different machinery (processing) hardening strength according to these grooves of manufacture method.For example, in case surpass the about 80% of thickness of workpiece when forming the degree of depth and the degree of depth in one direction, initial mechanical (processing) hardening stress is concentrated and is strengthened, because hardened material makes the brittleness increase.Its result is that when the rate of curving and specific elongation increase, workpiece is damaged easily.On the contrary, when this working depth less than about 80%, brittleness reduces and avoids the workpiece breakage, but its rate of curving and specific elongation reduce.In other words, corresponding to the wheel internal diameter varies under the various criterion, this balancing weight is not easy to bending and extension.This bad bending and extension cause the unstable bonding of balancing weight, thereby reduce attachment characteristic.In addition, the wheel diameters variation requires various balancing weights to have the multiple rate of curving and specific elongation, thus the reduction of the workability of showing as and productivity.
