Abstract
A method of assembling a wheel tire to a tire rim as a tire wheel is disclosed. The method comprises steps of measuring dynamic balances of a rim and a tire wheel formed by securing a tire to the rim, seeking static balances of the rim and the tire from these dynamic balances, and securing the tire to the rim by directing the direction of the static balance of the tire at 180.degree. opposite to the direction of the static balance of the rim.
Claims1
In a method of balancing and assembling wheels with tires wherein any unbalance of a tire and a rim are determined and the tire is secured to the rim in a position so that the vectors of balance necessary to achieve static balance of the tire and the rim separately are at least approximately directed opposite each other and any remaining unbalance is compensated by dynamically balancing the tire and the rim, the improvement comprising the steps of:
- determining the static balance force (R) of the rim by dynamic measurement of the balance;
- mounting the tire to the rim in any desired angular position without previously determining its unbalance or the corresponding static balancing force (T), determining by dynamic measurement of any unbalance the static balancing force (A) necessary for statically balancing the assembled tire and rim;
- determining the static balancing force (T) by vectorially substracting (T=A-R) the static balancing force of the (R) from the static balancing force of the assembled tire and rim (R) and, turning the tire on the rim so that the balancing force (T) is directed opposite the balancing force (R) of the rim.
