SINTERED FRICTION MATERIALS<\/h4>\n
Industrial applications
\nThe powder metallurgical friction materials are based on a sintered metal matrix, into which mineral, metallic, non-metallic or ceramic agents, as well as abrasives and solid lubricants are embedded. The formulation of the composite friction materials and the percentage of the metallic matrix determine significantly the good thermal conductivity and higher resistance to heat. Sintered friction linings are suited to operate in thermal highly loaded applications (e.g. clutches and brakes in drive technology, in machine industry and in heavy duty commercial vehicles including tractors, agriculture and construction machinery) for wet and dry running systems.<\/p>\n
During sintering processes powder mixtures are heated (sintered) to temperatures below the melting point and under controlled protective atmosphere. Thereby gases escape which leads to the typical open porosity of sintered friction materials. Even thinner sinter linings with high porous texture can be achieved by the sprinkling process, so as a result very porous friction layers support the cooling fluid and oil circulation. The production of sintered friction materials is carried out by ISO certified independent contract partners.<\/p>\n
WET-RUNNING BRAKE DISCS<\/h4>\n
Generally placed in the category friction discs, wet brake discs (in brake disc packages) operate in oil immersed multi-disc brakes and ball-ramp brakes, also known as wet-ramp brakes or ball-on-ramp brakes. Especially found in high engine tractors and heavy duty vehicles, wet brake discs are often just listed as lined brake discs. Additionally to disc linings (facings) made of organic based friction material for dry-running application, friction discs with sintered friction linings are, furthermore, required in oil-bath and wet-running conditions.
\n1) wet-running brake discs in various geometries
\n2) brake linings of divers friction materials (paper and graphite facings also available)
\n3) wide range of friction surface designs and groove patterns
\n…(Waffle, Sunburst, Radial, Spiral, Plan, Parallel, 2 and 3 pass multiple parallel, combinations)
\n4) backing support discs in various options, internal toothing (standard, reinforced)
\n5) matching intermediate discs<\/p>\n
FRICTION AND STEEL PLATES<\/h4>\n
Belonging to the category friction discs as well, friction plates and their counter plates (or opposing plates or discs) lined up in disc packs in non-positive friction clutches and friction brakes.
\nWhether installed in shifting clutches, safety clutches or holding brakes \u2013 multi-disc brakes and multiple plate clutches (also called multi-disc clutches or friction disc clutches) operate in various dry and wet running applications of drive and transmission systems. The technical design of friction materials and the shape and pattern of friction and steel plates depend on various parameters such as friction pairing, wear, surface pressure, temperature, rubbing speed, flow of oil, lubrication and more.
\n1) sinter bronze linings provided in different thickness (e.g. thin film of sinter by sprinkling process)
\n2) great variety of friction surface designs, groove patterns and oil channels
\n…(Waffle, Sunburst, Radial, Spiral, Plan, Parallel, 2 and 3 pass multiple parallel, combinations)
\n3) sinter layer fitting (single or double sided, ring facing or segmented, sintered \/ glued \/ riveted)
\n4) wet and dry running condition
\n5) friction disc alternatively lined with carbon, elastomer, graphite, paper based linings
\n\u2026(friction surface partner: steel, cast steel, grey cast iron)
\n6) inner and outer plates (drive profile: splines, lugs, slots)
\n7) steel counter plates and backing plates in required thickness
\n…(hardend, with grooving, recesses, sine wave)<\/p>\n
SINTERED FRICTION PADS<\/h4>\n
Attached to backing plates and grouped into the category of disc brake pads, sintered friction pads work in various caliper disc brakes. Due to the wide range of disc brake applications, released and activated in numerous ways whether electromagnetically, electromechanically, pneumatically, hydraulically, manually, spring-applied or non-releasing \u2013 the manufacturing of sintered brake linings is carried out according to custom specific criteria.
\nGoing through sintering method, the dry running friction materials will be processed to solid friction blocks or otherwise friction linings will be sintered upon prepared steel backing plates. Sintered friction materials are optimised to operate under extreme loads with low wear rate. With such characteristics they are particularly useful for yaw and rotor brakes in wind turbines. The multi-part arrangement of several cylindrical friction elements leads to a more uniform pressure distribution on the contact surface and reduces effects such as ‘hotbands’ and ‘hot spots’ on the brake disc’s surface.<\/p>\n<\/div><\/div><\/div>
