Embodiment 1

[0069] As shown in Figures 1 and 2, the hook is formed by stamping and heat treatment of SK5 steel strip, and its quenching hardness is HRC40-48. The surface of the hook is treated with white zinc plating.

[0070] The balance weight is formed by stamping 6mm thick Q235 low carbon steel plate, and the surface is plated with white zinc. The obtained balance weight has a specific gravity of 7.8 and a tensile strength of 375-500 MPa. After the hook and the balance weight are riveted, according to the different wheels, the surface is sprayed with silver-gray epoxy resin, and the average thickness of the coating is about 0.08mm.

[0071] The processing process of steel stamping balance weight:

[0072]

Embodiment 2

[0074] As shown in Figures 3 and 4, the hook is stamped and formed by 65Mn steel strip. After quenching and tempering, the hardness is HRC44~47, and then the surface is phosphating, and the coating thickness is 0.001mm.

[0075] The balance weight is made of ductile iron with an elongation rate of 15% through precision investment casting. After grinding to remove burrs, etc., the surface is phosphating. The specific gravity of the obtained balance weight is 7.3, and the tensile strength is greater than 400 MPa.

[0076] Then, the hook and the balance weight are riveted to form a riveted wheel balance device.

[0077] Spray silver-pink paint on the surface of the obtained riveted wheel balancer, and the average thickness of the coating is about 0.08mm.

[0078] Processing process of riveted balance weight:

[0079]

Embodiment 3

[0081] As shown in Figures 5 and 6, the hook is stamped from a 0.7-0.9mm 65Mn steel strip. After quenching and tempering, the hardness is HRC42-47, and then treated by Dacromet surface treatment.

[0082] The material of the balance weight is cast steel with a carbon content of 0.2%, and the balance weight body is formed by precision investment casting. Then spray epoxy resin paint on its surface, and the average thickness of the formed coating is about 0.08mm. The specific gravity of the obtained balance weight is 7.8, and the tensile strength is greater than 400 MPa.

[0083] When in use, the above-mentioned hook and the balance weight are assembled to the corresponding positions of the wheel rim.

[0084] The processing process of the assembled balance weight:

Abstract

The invention provides a wheel balancing device, comprising a balancing block and a clasp used to fix the balancing block on the wheel; wherein, the materials of the balancing block comprises low carbon steel with carbon content lower than 0.25%, ductile iron with the elongation of 5-18% or cast iron with carbon content lower than 0.3%. The invention also provides the preparation method of the wheel balancing device. The invention of the wheel balancing device has the advantages of cheap price and no pollution to the environment.

Description

technical field [0001] The invention relates to a steel and iron wheel balancing device and a manufacturing method thereof. Background technique [0002] Wheels include rims and tires. Since the weights of rims and tires cannot be made completely uniform, after the wheels are assembled or the tires are replaced, the center of mass of the wheels does not coincide with the geometric center of the wheels, resulting in static imbalance. A dynamic imbalance occurs after the rotation. As the speed of the vehicle increases, the force generated by the dynamic imbalance will cause the vehicle to vibrate, which will affect the driving comfort, safety and life of the vehicle. In order to overcome this defect, a dynamic balance test should be done after the wheel is assembled, so as to install a balance device at the corresponding position of the wheel, thereby eliminating the phenomenon of wheel movement imbalance. [0003] The balance device is used to adjust the dynamic balance of ...
