Abstract
Description
Technical field
[0001] The present utility model relates to the technical field of a spare part for a vehicle, specifically to a non-marking, adhesive wheel balancing weight. State of the art
[0002] The wheel balancing weight is a key spare part for ensuring the driving stability of the vehicle, which is attached by gluing to the surface of a hub to compensate for an imbalance moment when the wheel rotates.In current technology, ordinary double-sided foam adhesive tape is typically used as the adhesive medium for wheel balancing weights. However, this type of tape has obvious limitations in practical application: when removing the balancing weight, the tape can easily tear or separate, leaving adhesive residue on the hub surface. This not only makes cleaning difficult but can also negatively affect the hub's appearance. Furthermore, the tackiness and corrosion resistance of ordinary double-sided foam tapes are insufficient. Under complex operating conditions such as high temperatures or acidic / alkaline environments, the adhesive can easily fail, leading to the balancing weight detaching and affecting the wheel's balancing performance. Disclosure of the utility model
[0003] The technical problem to be solved by the present utility model is to provide a trace-free, adhesive wheel balancing weight for the defect mentioned in the above prior art.
[0004] To solve the aforementioned technical problem, the technical solution provided by the present utility model is: a non-marking, adhesive wheel balancing weight comprising an upper balancing weight body and a bottom adhesive component, which is a non-marking foam adhesive tape; for the adhesive component, from the direction of the balancing weight body outwards, a first adhesive film layer, a foam layer, a second adhesive film layer, a mixing intermediate layer, a third adhesive film layer and an insulating film layer are provided in the following order; The mixed intermediate layer is made of 21% PET materials and 79% foam materials.
[0005] Furthermore, the non-marking foam adhesive tape is attached to one side of the balancing weight body to allow for releasable bonding of the balancing weight body to a hub.
[0006] Furthermore, the intermediate mixing layer is closely bonded to the foam layer and the multiple adhesive film layers as a single-piece structure.
[0007] Further cleaning treatment methods include sanding and oil removal of the contact surface of the balancing weight body on the non-marking foam adhesive tape to ensure a clean contact surface free of contaminants.
[0008] One advantage of the present utility model over the existing technology is that the design of the mixed proportional distribution of PET and foam in the specific intermediate layer increases the tensile strength and the interlayer bonding strength of the adhesive tape, and the adhesive tape can be detached as a whole when the balancing weight is removed, thus avoiding the phenomenon of tearing, layering and residue of the adhesive layer, resulting in a trace-free effect; that the combination design of a substrate and an adhesive of the tape gives the product a super strong adhesive force, in combination with the soft property of the foam substrate, causes the balancing weight to fit snugly against the surface of the hub, increases the sealing effect and the adhesive stability, and reduces the risk of the balancing weight coming loose during the driving process; that the entire structure is simple, requires no additional auxiliary fastening part, the adhesive actuation is convenient, is adapted to the requirements of the assembly and application of the vehicle balancing weight, while simultaneously reducing subsequent maintenance costs.

[0013] Combined with Fig.The non-marking, adhesive wheel balancing weight comprises an upper balancing weight body (2) and a lower adhesive component (1). The non-marking foam adhesive tape is attached to one side of the balancing weight body (2) to allow the balancing weight body (2) to be releasably bonded to a hub. The adhesive component (1) is a non-marking foam adhesive tape. The adhesive component (1) has, in order from the direction of the balancing weight body (2) outwards, a first adhesive film layer (1.1), a foam layer (1.2), a second adhesive film layer (1.3), a mixed intermediate layer (1.4), a third adhesive film layer (1.5), and an insulating film layer (1.6). The mixed intermediate layer (1.4) is made of 21% PET materials and 79% foam materials. The mixed intermediate layer (1.4) is bonded to the foam layer (1.5).2), the several adhesive film layers closely connected as a single-piece structure, cleaning treatment methods of a contact surface of the balancing weight body (2) on the non-marking foam adhesive tape are sanding, oil removal to ensure the clean contact surface without contamination.
[0014] In the implementation of the present utility model, the balancing weight body is machined and manufactured from a lightweight alloy material commonly used for vehicle balancing weights, which serves to ensure a clean contact surface without contamination from grinding or oil removal from the surface on a side adjacent to the hub.
[0015] The non-marking foam adhesive tape is selected as the adhesive component; the mixing intermediate layer (1.4) of the tape is mixed and shaped according to the ratio of 21% PET material and 79% foam material; the thickness of the intermediate layer matches the thickness of the foam substrate to ensure the full flexibility of the tape after bonding; a conventional formulation adapted to the foam substrate is used for the adhesive film layers; the coating thickness is uniform to ensure consistent tackiness on both sides.
[0016] The first adhesive film layer (1.1) on one side of the non-marking foam adhesive tape is aligned and glued to a processing surface of the balancing weight body, uniform pressure is applied in the direction of the length of the adhesive tape so that the adhesive tape lies completely against the balancing weight body, no bubbles remain, and the pre-assembly of the balancing weight is completed.
[0017] During application, it is determined that the bonding position of the hub is clean and dry, and the ambient temperature is between 21 and 38 °C; the insulating film layer (1.6) on another side of the third adhesive film layer (1.5) is torn off, the balancing weight body is aligned to a specific balancing position, and after application, stable pressure is applied again so that the third adhesive film layer (1.5) is sufficiently immersed and in contact with the surface of the hub, enabling reliable bonding.
[0018] If the temperature of the primary bonding environment is lower than 10 °C, the bonding action should be carried out after reaching a suitable ambient temperature range; the unused, pre-assembled balancing weight should be stored in its original packaging, the storage environment should be maintained at 21 °C, a relative humidity of 50%, direct sunlight, rain and dust contamination should be avoided, the effective service life is 12 months from the date of manufacture.
[0019] In the present embodiment, the structural design of the non-marking foam adhesive tape directly affects the bonding and removal process of the balancing weight; the proportional distribution of the materials and the composite structure of the mixed intermediate layer (1.4) solve the problem of the residue of ordinary adhesive tape from the outset; at the same time, the adhesive stability and adaptability to the environment are ensured by their own properties, and the application requirements of the wheel balancing weight are met.
