Comprehensive tire abrasion testing machine

Abstract

The invention provides a comprehensive tire abrasion testing machine and relates to the technical field of tire abrasion testing machines. The comprehensive tire abrasion testing machine comprises a frame, wherein a rotation shaft is mounted on the frame; a power source is arranged and is connected with the rotation shaft through a transmission device; a rotation drum is arranged on the rotation shaft on the front side of the frame; a circular testing groove coaxial with the rotation shaft is formed in the rotation drum; a lateral deflection table is arranged on the front side of the rotationdrum and is connected with a rotation table driving device used for driving the lateral deflection table to rotate; a tire loading frame is arranged on the lateral deflection table; a guide rail is arranged on the tire loading frame; a sliding seat is arranged on the guide rail; a sliding seat driving device is arranged and is connected with the sliding seat; a tire shaft is arranged on the sliding seat; a wheel hub mounting disc is arranged at the end of the tire shaft; a force measuring sensor is arranged between the sliding seat driving device and the sliding seat. The comprehensive tire abrasion testing machine has the advantages that the tire is internally tangent to the road surface, the volume is small, the production cost and the usage cost are low, and the testing results are accurate.

Description

technical field [0001] The invention relates to the technical field of tire wear testing machines, in detail, it is a comprehensive tire wear testing machine which is inscribed with the road surface, the road surface can be replaced, is easy to use, can accurately measure the tire wear performance, and has great reference value for the use of tires. Background technique [0002] We know that the wear resistance of tires is the most important factor in determining the durability of tires. More than 98% of today's car tires are replaced or scrapped because of polishing. Therefore, wear has become the most concerned topic in tire design and production technology. The wear phenomenon of the tire is not only determined by the wear resistance of the tread rubber, but also greatly affected by the tire structure and pattern. Especially in the use of tires, the most common phenomenon of eccentric wear mostly begins to appear after the tire has been rotated for millions of times. T...

Problems solved by technology

(1) Flat tire testing machine: It is suitable for the study of the mechanical properties of tires at low speeds; it can only perform tests at relatively small speeds, resulting in the flat tire testing machine being basically unable to adapt to high-speed tire testing, and few people use it as a tire wear test

(2) Flat-belt tire testing machine: It overcomes the shortcomings of the flat-plate type, and can carry out mechanical research at high speeds. It also has a certain application range; but its cost is very high, and it is mostly used by large tire suppliers. The steel belt is easy to use. Fatigue damage, so the application of the flat belt testing machine has not been widely used

(3) Traditional drum tire testing machine: suitable for the study of steady and unsteady mechanical properties of tires at high and low speeds; the surface of the drum has curvature, which is different from the real road surface, and can only be tested when the diameter of the drum is large enough. Neglecting the influence of the curvature of the drum surface, the equipment is bulky
