摘要： A tire uniformity tester having: a spindle capable of rotating while holding a tire; a drum; a pressing mechanism that rotatably supports the drum and makes it possible to press a tire attached to the spindle into the drum through the relative movement of the drum and spindle; a uniformity measurement unit for measuring the uniformity of the tire during forward rotation and reverse rotation; and a control device. The control device controls the driving of the rotation of the spindle and the relative positions of the spindle and drum so that when the rotation direction of the spindle is reversed, the spindle and drum are separated from each other such that the spindle rotation speed reaches zero in a state in which the outer peripheral surface of the drum and the tire tread surface are not in contact with each other.

摘要： Data representing a ground contact time of a tire is transmitted from a tire side device, and received by a vehicle side device to calculate the ground contact time of the tire, to thereby calculate a ground contact length of the tire at that time. In a situation where a tire air pressure may change such as a tire exchange, the ground contact length at that time is set as a reference ground contact length, and a determination reference value is set on the basis of the reference ground contact length. As a result, the relative determination reference value corresponding to the tire type can be set, and a variation of the reduction rate of the tire air pressure when it is determined that the tire air pressure is reduced can be reduced. As a result, the reduction in the tire air pressure can be detected with high precision regardless of the tire type.
摘要翻译： 表示轮胎的接地时间的数据从轮胎侧装置传递，并且由车辆侧装置接收，以计算轮胎的接地时间，从而计算出当时轮胎的接地长度。 在轮胎气压变化等轮胎更换的情况下，将此时的接地长度设定为基准接地长度，并且基于参考接地长度来设定判定基准值。 结果，可以设定与轮胎类型相对应的相对判定基准值，并且可以减少当确定轮胎空气压力降低时轮胎空气压力的减小率的变化。 结果，无论轮胎类型如何，都可以高精度地检测轮胎空气压力的降低。

摘要： A measurement system scans the given surface of a tire component (e.g., a brush-finished tread or buffed tire casing) to electronically measure data points corresponding to vertical and horizontal coordinates along the given surface. Associated computer processors electronically calculate the slope at a plurality of different locations by determining the degree of steepness (e.g., rise over run, angle or grade) between selected ones of the first and second coordinates and electronically comparing at least one slope-based parameter to one or more predetermined levels to determine a characterization defining one or more of surface adhesion fitness, finishing brush wear level and brush bristle placement location. Slope may be determined between every adjacent pair of data points or between selected data points (e.g., identified local maximum and minimum). The at least one-slope based parameter compared to the predetermined levels may correspond to the slopes themselves or to a calculated average slope value.

摘要： A device for rotating a tire includes a fixed support, a driving belt, a plurality of first pulleys, and at least one second pulley. The driving belt has a contact face for contacting an annular part of the tire, and the driving belt enables rotation of the tire. The first pulleys are mounted on the support and are in abutment with the driving belt on a side opposite to the contact face in order to press the contact face radially against the annular part of the tire. The at least one second pulley is in abutment with the contact face of the driving belt and is mounted for translational movement on the support in order to locally space the contact face apart from the annular part of the tire.

摘要： A tire characteristic determination system is disclosed. The tire characteristic determination system includes a memory device that stores tire-engaging data related to one or more tire-engaging value to be utilized for spatially manipulating a tire about a wheel for forming a tire-wheel assembly. The tire characteristic determination device includes a tire-engaging test probe that is urged adjacent the tire at one or more tire displacement distances or is urged against the tire with one or more amounts of urging forces. The tire characteristic determination device is communicatively-coupled to the memory device for communicating the one or more tire displacement distances or the one or more amounts of urging forces to the memory device.

The wear measurement system includes a casing placed on a ground surface. The speed evaluation system further includes a timing device that determines at least two instants of passage of the vehicle over two distinct or non-distinct points of passage of the casing of the wear measurement system, and a processor that calculates, as a function of the instants of passage and of dimensional data of the casing and/or dimensional data of the vehicle, a speed of passage of the vehicle over the casing. A method of implementing the speed evaluation system also is provided.
