Description
Technical field
The present invention relates to field of compound material, particularly a kind of clutch coupling friction materials.
Background technology
Clutch coupling friction materials is that medium-to-high grade automobile is as the critical material of transferring power in the arrangement of clutch of car, minibus and other motor vehicle and the use of various heavy-duty machinery.
Clutch coupling is different by Properties of Friction Materials, but conventionally all binding agent, fortifying fibre, abrasive material, lubricant, the large class material of filler five, consists of.In the 20-70 age in 20th century, containing the composite friction material of asbestos, be almost to rule all the land, adopt containing the composite friction material of asbestos and there is good performance and price as the brake friction material of various Motor vehicles.From 1972, international tumour medical association's confirmation asbestos and vaporization at high temperature thing belonged to carcinogens, start in the world the tide that one bans use of asbestos friction material, in the Friction Materials of nearly more than 30 years, the overwhelming majority concentrates on without asbestos composite friction material aspect.In replacing the fiber of asbestos, except steel fiber, more common having at present: the assorted fibre that glass fibre, carbon fiber, aramid fiber and these fibers mix mutually.
With steel fiber or metal powder (cast iron powder, reduced iron powder), replace fibrous magnesium silicate, application number: 89100843.8, semimetal friction material; Application number: 92106617.1, semi-metallic asbestos-free sedan brake disk and production method thereof.In use find that semimetal friction material exists following shortcoming: steel fiber gets rusty easily, after corrosion or occur adhesion antithesis or damage antithesis, make friction plate strength decreased, wearing and tearing aggravation, stable friction factor variation; Although semimetal friction material has been eliminated the high frequency noise that asbestos friction material easily produces, and easily produces the low frequency noise under low speed.
The feature of glass fibre is that hardness is high, better heat stability, good, cheap with resin affinity.Glass fibre developing history is longer, is in early stage asbestos-free friction material, to use more fiber.Application number: 02112952.5 asbest-free friction material reinforced base material and manufacturing process thereof, introduced the main composite friction material containing glass fibre.In use glass fibre friction materials all shows higher wear rate, glass fibre much higher hard and plasticity extreme difference is also one of reason causing high wear rate.Also can produce scratch and wearing and tearing by mating plate, under heavily loaded high temperature, frictional coefficient fluctuation is larger, less stable simultaneously.
Aramid fiber claims again Kevlar fiber, is the organic regenerated fiber of a kind of aromatic poly amide, is the product of du pont company's exploitation.Application number: 200610200693.4, a kind of fiber mixture reinforced friction material and preparation method thereof, has introduced the main composite friction material containing aramid fiber.It is characterized in that having under quite high intensity and toughness, medium modulus, very little density, wear-resisting, heat-resisting, high temperature dimensional stabilizing good, the fragility that does not have carbon fiber and glass fibre to present.But the content of in use finding Kevlar in friction materials can produce larger impact to its tribological property.When the content of Kevlar surpasses 10%, frictional coefficient reduces by 50%, and wear rate reduces an order of magnitude, but Kevlar content continues increase, and frictional coefficient remains unchanged substantially, and wear rate increases and continues to decline with Kevlar content.This shows, Kevlar adds the wear resistance that has greatly improved friction materials, but its frictional coefficient also declines thereupon.Although the friction materials that aramid fiber strengthens has extremely significantly wear resistance advantage, and has also arrived gratifying result in service testing, the reduction of the frictional coefficient causing is thus that Automotive Friction Material is undesirable.
The outstanding advantages of carbon fiber organic-type friction material is its high temperature friction good stability, wear-resisting.Application number: 200410075132.7, containing the friction materials of partially carbonized carbon fiber.But due to higher price promoting the use of of it.
In sum, the development of modern friction materials must be when considering to reduce friction materials production and adding the environmental pollution in man-hour, also must consider and pollution in use of friction materials and the contamination to environment of the friction materials scrapped, and the various factors such as the cost of friction materials and performance.Along with the development of technology, existing friction materials more and more can not meet the service requirements of clutch disc.
