Description

Technical Field

[0001] The utility model relates to the technical field of vehicle balance weights, and more specifically, to a wheel balance weight. Background Art

[0002] The mass of each part of any object will be different. Under static and low-speed rotation, the uneven mass will affect the rotation stability of the object. The higher the rotation speed, the greater the vibration. With the improvement of highway conditions and the rapid development of automobile technology in our country, the driving speed of vehicles is also getting faster and faster. If the mass of the automobile wheel is uneven, during this high-speed driving process, it will not only affect the riding comfort, but also increase the abnormal wear of the automobile tires and suspension systems, increase the difficulty of controlling the vehicle during driving, and lead to unsafe driving. To avoid this situation, the wheel must be subjected to a dynamic balance test by a special device - a wheel dynamic balance machine before installation, and an appropriate counterweight is added to the place where the wheel mass is small, so that the wheel maintains dynamic balance under high-speed rotation. This counterweight is the wheel balance weight. The role of the vehicle balance weight is to minimize the mass difference of the wheel to achieve a relatively balanced state. Due to the complex road conditions, any situation on the road may affect the tire and the steel rim, such as hitting the curb, passing through a pothole road at high speed, etc., which is likely to cause the steel rim to deform. In severe cases, it is necessary to re-do the tire dynamic balance and re-do the balance weight counterweight. The existing balance weight is flat, does not fit tightly with the wheel rim, and has too large a balancing radius, which is likely to cause inconvenient balance counterweight and poor counterweight effect.

[0020] Aiming at the problems of inconvenience and non-sealing in the fitting of the current wheel balance weight to the wheel rim, the present utility model provides a wheel balance weight, which solves the problems of inconvenience and poor effect when the existing wheel balance weights are used for wheel balance and counterweight, can improve the convenience of vehicle dynamic balance maintenance, and improve the safety of the vehicle.

[0021] As Figure 1 shown, a wheel balance weight includes: a counterweight block 1 and a double-sided adhesive tape 2. The counterweight block 1 is in a long strip curved structure and is adapted to the curvature radius of the wheel contour curve, and the double-sided adhesive tape 2 is provided on the bottom surface of the counterweight block 1. An envelope contour is provided on the top surface of the counterweight block 1 and is adapted to the layout envelope of the wheel.

[0022] Specifically, the counterweight can optimize the balance weight profile according to the curvature of the wheel's mating surface, the trimming radius, and the position requirements to ensure a perfect fit between the two; according to the unbalance amount displayed by the dynamic balancing machine, it can automatically and precisely cut the balance weight of the corresponding weight to achieve precise trimming, avoid material waste, and save costs. The outer contour curvature of the counterweight is the same as the curvature of the wheel's mating surface, so that it can be smoothly attached to the wheel after removing the double-sided adhesive tape of the balance weight, and it also avoids damaging the wheel when assembling the balance weight. It can solve the problems of inconvenience and poor effect existing in the use of existing wheel balance weights for wheel balance counterweights, improve the convenience of vehicle dynamic balance maintenance, and improve the safety of the vehicle.

[0029] Further, a groove 11 is provided in the middle of the counterweight to facilitate the bending of the counterweight according to the set curvature.

[0030] Further, the groove 11 is in a U-shaped structure.

[0031] In an embodiment, the required trimming radius of 261 mm on the inner side of the rim is selected, and the thickness of the balance weight is mm, where the thickness of the counterweight of the balance weight is 4 mm and the thickness of the double-sided adhesive tape of the balance weight is 1 mm. The wheel data is opened using catia software, the wheel contour surface at the trimming radius of 261 mm is selected, and the layout envelope of the inner side balance weight of the rim along the entire wheel is generated according to the balance weight thickness of 5 mm. Similarly, the layout envelope of the outer side balance weight of the rim along the entire wheel can also be generated; the obtained balance weight envelope is a balance weight profile that fits extremely well with the adhered surface, ensuring a smooth fit between the balance weight and the wheel.

[0032] In practical applications, after the tire and wheel are assembled and detected by the dynamic balancing machine, the unbalance amount and the key position angle of the wheel assembly will be displayed. According to the unbalance amount displayed by the dynamic balancing machine, the balance weight of the corresponding weight is cut, and the double-sided adhesive tape of the balance weight is torn off and pasted at the displayed position angle to complete the preliminary trimming, and then the entire wheel assembly pressing process is completed through re-inspection, appearance inspection, etc.
