Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to an alloy wheel restoration apparatus, and more particularly, to a means for easily calibrating a rim of an alloy wheel so that damage to an expensive alloy wheel can be restored and reused, thereby increasing the life of the alloy wheel And more particularly to an alloy wheel restoring device for preventing frequent replacement.

BACKGROUND ART [0002] In recent years, automobile wheels have been developed from conventional one-piece wheels, and are now being developed into two-piece and three-piece wheels.

The one-piece wheel is a wheel in which both a rim portion and a disk portion are formed in one lump, and a two-piece wheel is a structure in which a rim portion and a disc portion are separated. The three- Since the part is separated into the inner rim and the outer rim part, the structure of the three-piece is adopted for the expensive wheel.

In addition, since the alloy wheel is a circular object and rotated at a high speed, unbalance generated in the alloy wheel greatly affects the traveling state of the vehicle. Therefore, in order to compensate for the unbalance of the alloy wheel, a balance weight is provided on the rim of the alloy wheel to prevent uneven weight.

In order to find out the position of the weight on the alloy wheel, the alloy wheel is supported by the shaft, and when it is made to rotate lightly, the heavy weight is lowered downward. The balance weight is mounted at the opposite position corresponding to the position, Thereby preventing vertical vibration of the alloy wheel.

In addition to the static unbalance, the dynamic unbalance must be considered. Even when the static unbalance is corrected, when the actual alloy wheel is rotated, the all-wheel wheel vibrates in the left-right direction and the alloy wheel vibrates. This is because the balances are not balanced on the right and left sides. In this case, balancing is performed by mounting the balance weights of the same weight at symmetrical positions.

When the inner rim and the outer rim of the vehicle wheel are bent, even if the specialist is a specialist in the wheel, the refracting portion is directly restored to a circular shape by applying a physical force directly to the bent portion, and then the state of the wheel is measured The balance weight is attached to the opposite side of the inner and outer rims of the rim as the measured value on the opposite side of the repaired area. In this case, there is a fundamental problem that the driver does not feel at the time of driving, but the 100% circular restoration is not made in the state of the first new product.

The repair of the vehicle wheel according to the related art is performed so that the inner rim and the outer rim portion are greatly different from the original structure when repairing the vehicle wheel many times, so that the driver's steering wheel is vibrated even though the balance weight is attached Thereby causing the user to feel uncomfortable.

In the related art, Korean Patent Laid-Open No. 10-2011-0094771 (published on Aug. 24, 2011) discloses a vehicle wheel repair device.

However, when the wheel to be repaired is seriously damaged, the wheel must be repaired by a hand hammer before it is inserted into the first repair part and fixed, and even if repair is performed using the hammer, There was a problem.
