Abstract: A testing machine for tires has a base, a first slider, a second slider and a brake arm. The tire testing machine can test the tire's tread and bead lip at the same time, and then obtain the test data of the tire's plunger requirements and the ability to remove the lip, which can effectively reduce the time and labor for the tire's replacement and transfer cost, thereby improving the test efficiency of the tire, and helping to improve the accuracy of test data integration and analysis, and through the design feature of one machine, it can also reduce the cost of machine purchase and the doubt about placing the machine space, which have substantial effects of practicality and convenience.

Abstract: A plastometer has: a main frame, a driving unit, an electromagnet, a loading dock, a lower mold, an upper mold and a measuring unit the driving unit drives the lifting platform, so the lifting platform makes a stable elevating displacement along the two supporting columns. Then, the electromagnet attracts and controls the loading dock, so the pressure amount to be provided by the loading dock for each test object 80 can be simply obtained, and the measurement operation is actually performed by the measuring unit which can get accurate test results to improve the measurement efficiency of the relevant industry.

Abstract: A transmission structure of an ozone testing machine has: a transmission frame, a rotation unit, a connecting unit, and a lifting unit. The transmission structure is connected to the lifting shaft and the lifting device via the connecting unit, the bottom of the sleeve of the connecting unit is provided with threaded member screwed to the threaded rod of the lifting device, and the sleeve is fixed onto the sliding member to achieve the linear displacement along the guiding track. During the clockwise and reverse rotations of the servo motor of the lifting device, the lifting shaft can achieve the synchronous operation of the rotation and lifting due to the limited connection with the connecting unit, thereby greatly improving the smoothness of the test process, while maintaining the static and dynamic tests.

Abstract: A tire rolling resistance testing machine has: a main testing set, an X-axis sensing member and a Y-axis sensing member. The X-axis sensing member and the Y-axis sensing member are configured for testing the tire, wherein the first connecting member and the second connecting member are floatingly mounted between the two X-axis positioning plates and the two Y-axis positioning plates which allow the axial rod to be placed through and perform the test. This design greatly improves the sensitivity of the first connecting member and the second connecting member, and avoids the mutual interference between the X-axis moment and the Y-axis moment when the tire is tested. Therefore, the precision of the test and the accuracy of rolling resistance data is improved.
