Abstract
The friction material comprises at least one polyimide and/or polyamideimide in combination with at least one phosphate chosen from the groups of alkali phosphates, alkaline earth phosphate and ammonium phosphates.
Description
Friction material
The invention relates to friction materials and mixtures of substances for producing friction materials, which are intended in particular for use in clutch disks and brakes, i.e. for transferring or bracing torque. Friction materials that consist of a mixture of different substances are known.
Friction materials for use in connection with clutch disks consist for example of a mixture of fibers such as mineral fibers, filler and binder, as well as possibly other additives that affect the friction and wear properties as well as temperature resistance.
The object of the present invention was to create friction material compositions or mixtures for the production of friction materials and friction linings made from them, which are tolerant of high thermal and mechanical demands and nevertheless ensure a relatively high coefficient of friction. Furthermore, good consistency of the coefficient of friction should continue to be ensured over a wide temperature range. In addition, the mixtures according to the invention and the friction linings made thereof should ensure practically grab-free torque transfer through frictional engagement, whereby driving comfort can be significantly increased for example by the use of such friction linings in connection with motor vehicle clutch disks.
The tasks underlying the invention are addressed according to an exemplary embodiment wherein the friction material consists of at least two component substances, which include at least one polyimide and/or polyamideimide in combination with at least one phosphate of the heavy alkaline phosphates, alkaline earth phosphates and ammonium phosphates.
The tasks according to the invention can also be addressed in an advantageous manner by using friction linings which are produced on the basis of a mixture of component substances that contains at least one polyimide and/or polyamideimide in combination with at least one metal sulfide. Instead of at least one metal sulfide, or in addition thereto, at least one metal oxide may also be used.
Using a polyimide makes it possible to increase the temperature resistance of the friction lining significantly, since polyimide tolerates high temperatures, for example up to approximately 400° Celsius. Adding at least one phosphate from the groups of alkaline phosphates, alkaline earth phosphates and ammonium phosphates makes it possible to increase the coefficient of friction while retaining relatively low wear of the friction

© WO 2006/057042 PCT/DE2004/002513 material. In an advantageous way, the proportion of phosphate can be 1 to 25 weight percent. Weight percent means the weight-based proportion of the total weight of dry mixed component substances. The percentages by weight of most of the substances that make up a friction lining are also present in the finished friction lining. It has proven to be especially advantageous to use tricalcium phosphate and/or trisodium phosphate.
Admixing at least one metal sulfide also makes it possible to produce friction linings with good wear resistance. It has proven to be especially effective to use at least one of the following sulfides, namely tin sulfide, bismuth sulfide, iron sulfide or manganese sulfide.
If at least one metal oxide is used, then tin oxide and/or zinc oxide and/or manganese oxide and/or iron oxide may be used advantageously.
The proportion by weight of polyimide and/or polyamideimide can be 20 to 60 percent.
These substances can be admixed in a resiniform and/or powdered and/or granular state or a combination of those structures.
Other resiniform, powdered or granular binders can also be admixed advantageously.
In order to be able to adapt the wear and friction properties of the particular use, it can be advantageous to admix at least one of the following metals, namely copper, brass, tin and zinc. The proportion of metal can be 1 to 30 weight percent. Such metal additives can be added in the form of powder, fibers or chips.
Furthermore, at least one filler can be added advantageously which may be at least one of the following substances, namely barium sulfate, calcium carbonate, kaolin, microscopic hollow spheres, magnesium carbonate. The proportion of filler can be 10 to 50 percent.
Fibers that consist of at least one of the following fiber types can also be admixed advantageously, namely carbon fibers, aramid fibers, glass fibers, metal fibers, ceramic fibers.
The use of such fibers makes it possible to increase the bursting strength of the friction lining. However, employing such fibers also makes it possible to adjust the friction coefficient of the friction linings so constructed, and also their wear performance, to the specific application. The total proportion of fibers can be 1 to 50 weight percent.
Furthermore, it can be especially effective if lubrication is admixed which may consist of at least one of the following substances, namely coke, graphite, carbon black, metal sulfide. Admixing such substances also makes it possible to affect the wear behavior and the friction coefficient of the finished friction lining. For example, by mixing in coke, graphite etc. a friction coefficient that is initially too high can be reduced to a desirable value, while at the same time the wear resistance of the friction lining can be increased, at least with some mixtures.
Advantageously, the total weight proportion of phosphates and lubricants is 10 to 50 weight percent.
