Embodiment 1

[0065] figure 1 , is the structure diagram of the rim designed in the embodiment of the present invention. The rim of the tire dynamic balancing testing machine includes an upper rim and a lower rim. In this embodiment, only the upper rim is described. Four T-shaped grooves 1 are respectively opened in the orthogonal direction on the surface of the rim, and two sets of T-shaped bolt-nut structure pairs with masses of 10g, 20g, 30g, 50g, and 100g are configured. T-bolts and matching nuts can be designed and manufactured by selecting appropriate materials according to the size of the rim and the size of the T-slot, and will not be described in detail in this embodiment. The T-shaped bolt can be moved and fixed in the T-shaped slot, and the T-shaped slot 1 can have a scale 4 to facilitate the measurement and adjustment of the T-shaped bolt. Four threaded holes 3 for loading weights during the calibration process are provided at specific positions on the edge of the rim.

Abstract

The invention discloses a dynamic compensation wheel rim for compensating system unbalance of a tyre dynamic balancing testing machine and a method. The invention aims to solve the following problems that the relatively great system unbalance of the tyre dynamic balancing testing machine affects the test precision and resolution of the system; an eccentric compensation algorithm and operations are only used for calculating the system unbalance mass and cannot achieve real compensation of the system unbalance; currently some compensating devices require great modification of a conventional structure; and a counterweight correcting face and a measurement correcting face are not consistent. Four T type grooves with scribed lines are arranged on the orthogonal direction of the wheel rim. Counterweight blocks are further arranged. Each counterweight block group is a pair of T type bolt-nut pair structure matching the orthogonal T type grooves in terms of the dimension. The system unbalance can be lowered to an ideal range through the combined movement of the counterweight blocks with a known mass. The equipment detection precision is effectively improved.

Description

technical field [0001] The invention relates to a wheel rim and a method for dynamically compensating the unbalanced amount of a tire dynamic balance testing machine system. Background technique [0002] The large residual unbalance mass of the human tire dynamic balance testing machine system itself affects the detection accuracy and resolution of the equipment. If the unbalance amount of the tire to be tested is much smaller than the unbalance amount of the equipment itself, it is difficult to identify and extract the weak tire unbalance vibration signal, and the weak signal may even be submerged. When the unbalance of the tire to be tested is large, the joint action of the two unbalanced centrifugal forces will introduce greater vibration and noise, which will deteriorate the signal-to-noise ratio and cause crosstalk to the vibration signal. Exacerbating the wear of key structures such as the main shaft and bearings can easily cause overload or even damage to the sensor,...
