Belt driving type rubber friction characteristic test system

Abstract

The invention discloses a belt driving type rubber friction characteristic test system which mainly consists of a support frame (3), a clamp module (1) and a pavement dynamic system (2), wherein the clamp module (1) and the pavement dynamic system (2) are fixed above the support frame (3); a pavement conveyer belt in the pavement dynamic system (2) moves under the driving of a motor; a hydraulic loading cylinder in the clamp module (1) applies load to a rubber sample to be detected below the hydraulic loading cylinder so as to enable the rubber sample to get frictional contact with the pavement conveyer belt and collect the pressure of the rubber sample through a pressure sensor. The belt driving type rubber friction characteristic test system can be used for realizing the measurement of frictional coefficient between rubber tire treads and pavements under different working conditions, truly reflecting the characteristics of automobile tires with different tire tread patterns at various sliding velocities and overcoming the limitations of traditional racks due to rubber size, sliding velocity and sliding distance.

Description

technical field [0001] The invention belongs to the field of tire tribology research, in particular to a belt-driven rubber friction characteristic test system, which can provide effective test means for the friction and wear properties of tire tread rubber materials. At the same time, it can provide a platform for measuring the friction characteristics of tires and road surfaces at different speeds. Background technique [0002] As the main component of tires, rubber has special friction characteristics, which do not conform to Coulomb's law of friction. The mechanical properties of rubber tires largely depend on the friction properties of rubber (especially in some extreme conditions). At present, the theoretical research on rubber friction is still immature. Therefore, the test research of rubber friction is very important to the research of tire mechanical properties. [0003] On the other hand, tire tread pattern is an important factor to improve automobile performan...

Problems solved by technology

[0005] The sample size of the turntable friction table test should not be large, because when the rubber sample slides on the turntable, the sliding speed of the inner and outer sides is inconsistent. The smaller the turntable or the larger the test sample size, the more obvious this phenomenon is, and it is difficult to test. Experimental test of rubber blocks; sliding table type friction table sliding speed, sliding displacement is small, limited by the actual size of the plate type, the maximum friction speed of rubber is difficult to increase
