Problems solved by technology

Although the rubber abrasion machine mentioned above is widely used, it cannot realize rolling and sliding friction at the same time. It has the disadvantage of studying the single form of rubber friction and cannot reproduce the complex friction behavior between the tire and the ground.
In addition, the above-mentioned abrasion machine can only measure the rubber wear performance at normal temperature, so it cannot better reflect the influence of temperature rise on the rubber wear performance due to the viscoelastic heat generation of the rubber material during the high-speed rolling of the tire.

Abstract

The invention relates to a temperature-variable abrasion instrument capable of studying the rolling and sliding friction behaviors of rubber simultaneously. The instrument comprises a grinding wheel and an abrasion wheel contacting the grinding wheel. The circumferential direction of the abrasion wheel contacts the end face of the grinding wheel. The rotation of the grinding wheel drives the rotation of the abrasion wheel. The abrasion wheel and the grinding wheel generate rolling friction and sliding friction at the same time. According to the invention, the abrasion instrument can simultaneously measure the rolling friction and sliding friction behaviors of rubber, so as to acquire the abrasion amount under two friction situations; with the gradual increase of the amount of depressionof a cylinder, the friction behavior of the rubber ring of the outer ring of the abrasion wheel on the grinding wheel is changed from sliding-based friction to rolling-based friction; and the application range of the instrument is greatly expanded.

Description

technical field [0001] The invention relates to a temperature-variable wear instrument capable of simultaneously measuring rubber rolling friction and sliding friction behavior, which mainly reproduces the complex friction behavior of rolling tire tread contacting the ground. Background technique [0002] At present, the traditional rubber abrasive machines mainly include Akron abrasive machines, DIN abrasive machines and so on. The Akron Abrasive Machine is mainly used to study the rolling wear properties of rubber materials, while the DIN Abrasive Machine can only obtain the sliding wear properties of rubber materials. Although the above-mentioned rubber abrasion machine is widely used, it cannot realize rolling and sliding friction at the same time. It has the disadvantage of studying the single form of rubber friction and cannot reproduce the complex friction behavior between the tire and the ground. In addition, the above-mentioned abrasion machine can only measure the...
