Automatic-controlled friction and abrasion performance testing machine

Abstract

The invention relates to an automatically controlled friction and wearing performance testing machine. MM1000 type friction performance testing machine in the prior art is one of the machine types that are used in friction material filed in nineteen eighties, which, however, has a structure incapable of adapting to automatic control and an unscientific data collection means. With the purpose of solving the problem, a press-plate clutch realized via pneumatic actuating means is adopted for the testing machine of the invention and a bottom pendulum or intermediate pendulum cylinder is adopted as a thrust cylinder. The invention has a systematic reconstruction with regards to all manual operation means, structural parts not adapting to automatic control and unscientific data collection means; testing methods for dry and wet friction material are set up and an inertia test of imitation braking of hand sample shrinkage ratio is completed in a laboratory. The invention is widely used for the friction and wearing performance test on the friction and wearing materials in such fields as airplane, military vehicles, automobiles, ships, rail traffic and engineering machinery.

Description

Technical field: [0001] The invention relates to an inertia testing machine which simulates braking with a small sample scale under laboratory conditions. It is a testing device for friction and wear and thermal shock braking tests on dry and wet friction materials. The operation process is fully automated. It is an automatic control friction and wear performance testing machine. technical background: [0002] In the prior art, the MM1000 friction performance testing machine is one of the models used in the friction material industry in the 1980s, but it has a structure not suitable for automatic control and an unscientific data collection method. [0003] The QM1000-II wet friction material performance testing machine improved by the inventor has also obtained a national patent, the announcement number: CN2569129, which is improved on the basis of the MM1000 type, and successfully realizes the collection of instantaneous values, and is only suitable for wet friction materia...
