no. 2 Embodiment approach

[0048] The steps of measuring the resistance value of the tire 5 in the second embodiment are only different from the first embodiment in the two working steps S6 and S7 shown in the first embodiment, and the other working steps are the same as in the first embodiment, so the descriptions are omitted. Description of other job steps. The four first probes 2 are brought into contact with the central part of the width of the tire 5 (the width of the tread portion 6) that divides the tread outer peripheral surface of the tire 5 into four equal parts, and then the second probes 2 mounted on the rotating member are The probe 3 is in contact with the side wall surface of the bead portion 9 (S6), and while the resistance measuring device 1 is powered on, the second probe 3 is rotated once to measure the distance between the tread portion 6 and the bead portion 9. between the resistance value (S7).

no. 3 Embodiment approach

[0050] The steps of measuring the resistance value of the tire 5 in the third embodiment are only different from the first embodiment in the two operation steps S6 and S7 shown in the first embodiment, and the other operation steps are the same as in the first embodiment, therefore, the descriptions are omitted. Description of other job steps. Four columnar first probes 2 are brought into contact with the central part of the width of the tire 5 (the width of the tread portion 6 ) that divides the outer peripheral surface of the tread portion 6 of the tire 5 into four equal parts, and then mounted on a normal The second probe 3 on the gripping member of the first contact with the side wall surface of the bead portion 9 (S6), while turning on the power of the resistance measuring device 1, rotate the tire 5 to be measured by a normal rotating member for a while, While measuring the resistance value between the tread portion 6 and the bead portion 9 (S7). In addition, the reason...

Abstract

The present invention provides a tire resistance measuring device and its measuring method. The measuring device and its measuring method can be used to measure the tire resistance without taking a long time, and can maintain the measurement accuracy and ensure the electrical conductivity of the tire. The tire resistance measuring device (10) of the present invention has a first probe (2) and a second probe (3) for measuring the resistance value of a tire (5), and is characterized in that the first probe (2) ) is in contact with a plurality of locations on the outer peripheral surface of the tread portion (6), one of the above-mentioned second probes (3) is in contact with the central peripheral portion of the tire (5), and the measurement of the tread portion (6) and the bead resistance value between parts (9).

Description

technical field [0001] The present invention relates to a tire electrical resistance measuring device and a measuring method thereof for measuring the electrical resistance of a tire in which a conductive rubber is incorporated into a tread rubber. Background technique [0002] Conventionally, in order to improve the rolling resistance of tires, low-conductivity materials such as silica have been blended into tire rubber. This increases the rolling resistance of the tire, but increases the resistance value of the tread rubber. As a result, static electricity generated in the vehicle becomes difficult to discharge to the road surface. Therefore, a method of manufacturing a tire by sticking a sheet of tread rubber layer in which conductive rubber is mixed to a building drum is adopted, in which the electrical resistance of the tread rubber layer is adjusted before molding. value is measured. In order to improve the measurement accuracy of the resistance value, it is necessar...
