Abstract

The embodiment of the present invention discloses a method for measuring unbalance of a spindle in measurement of dynamic balance of a tire, which comprises the following steps: carrying out first measurement of the dynamic balance of the tire and calculating to obtain an equivalent unbalanced force vector of the first measurement; rotating the tire connected with the spindle for a certain angle while ensuring that the spindle is fixed, carrying out second measurement of the dynamic balance of the tire, and calculating to obtain an equivalent unbalanced force vector of the second measurement,calculating to obtain an equivalent unbalanced force vector of the spindle according to the equivalent unbalanced force vector of the first measurement and the equivalent unbalanced force vector of the second measurement; and calculating to obtain the unbalance of the spindle and determine the part of the spindle with the unbalance according to dynamic balance conditions and the equivalent unbalanced force vector of the spindle. The embodiment of the present invention also discloses a tire balancing machine. By adopting the method and the tire balancing machine, measurement errors resulting from the unbalance of the spindle can be eliminated by the testing personnel during the dynamic balance of the tire, and more accurate tire unbalance of the tire can be obtained.

Description

technical field [0001] The invention relates to the field of tire dynamic balance measurement, in particular to a method for measuring the unbalanced amount of a main shaft in tire dynamic balance measurement and a tire balance machine. Background technique [0002] With the development of China's automobile industry and the continuous growth of China's automobile market, the demand for tire balancers is increasing. However, the research and development and production of tire balancers in China are relatively backward. [0003] Unbalance is caused by the failure of inertial force or centrifugal inertial force to be eliminated. Unbalance is a vector. During the tire manufacturing process, the center of gravity of the tire does not coincide with the center of the rotation axis, and when it rotates around the axle, it generates inertial forces of different sizes in various directions. Tire imbalance is divided into two types: static imbalance and even imbalance. Tires with s...
