Problems solved by technology

[0005] Due to the above-mentioned differences in supporting the test tires, as a single measuring device simultaneously measures the uniformity and dynamic balance of the test tires, and at least two devices must be used to perform these two measurements, so a large space is required and expensive,
[0006] Moreover, in the conventional tire uniformity measuring device, although there are different widths according to the type of the test tire, a tire mounting unit can only mount one type of tire (width), therefore, it is necessary to be able to And changing the mandrel installation unit is quite cumbersome and costly
[0007] Moreover, in the traditional dynamic balance measurement device, it is difficult to inflate the test tire, and when passing through the device, the fine particles will not be poured in, which will affect the measurement result

Embodiment Construction

[0039] The tire uniformity and / or dynamic balance measuring device implementing the present invention will be described below, and please refer to the accompanying drawings.

[0040] FIG. 1 and FIG. 2 are a front view and a plan view, correspondingly showing the basic structure of the measuring device 1 . In the following description, the definitions of "upper" and "lower" are as indicated in Fig. 1. However, it should be understood that the measuring device 1 may be constructed in a vertically reversed direction, or arranged in a horizontal direction without seeing It needs to be used as explained in the text.

[0041] The stand of the measuring device 1 includes a base 50 , a support 52 extending upward from the base 50 , and a base 50 supported by the support 52 . The spindle 100 is mounted on the base 50 and holds and rotates a test tire T. As shown in FIG.

[0042] Firstly, a test tire support system is described, and please refer to FIG. 3 . FIG. 3 is a partial view o...

Abstract

A measuring apparatus for the uniformity and / or the dynamic-balance of a tire is disclosed. The apparatus comprises a supporting member which is rotated with supporting a tested tire, a holding member which holds said supporting member with allowing to vibrate during rotation thereof and a regulating system which prevents the vibration of the supporting member during rotation thereof. The vibration of the supporting member is prevented by the regulating system for a uniformity measurement while it is allowed during a dynamic-balance measurement.

Description

technical field [0001] The invention relates to a tire uniformity and / or dynamic balance measuring device, in particular to a structure supporting a tire in a rotatable manner. Background technique [0002] There are existing devices on the market for measuring the uniformity of tires, which only measure the uniformity of test tires, and there are also devices for measuring the dynamic balance of tires, which only measure the dynamic balance of test tires. [0003] The uniformity measuring device is constructed to rotate a tire by pressing the rotatable drum against the outer peripheral surface of the tire, and to measure variations in load in the radial direction and in the pushing direction. The uniformity measuring device must be constructed so as to safely and securely support the test tire when a load of 100 kg or more is applied to the test tire by rotation. [0004] On the other hand, the dynamic balance measuring device detects the centrifugal characteristics of the...
