Description

Pio innovation concerns a cleaning block for licensing of original clips bon, in particular of motor vehicle disc brakes.

The ifi; i hj-nui'ung der friction brakes «ml -clutches are generally ordered uus the actual Heibmaterinl and the (»egenroibf lache, which at Motor vehicles is part of a Drem drum or brake disc. Ueim brake or clutch the two Kcihpartncr engaged. In this case, the surface, which is mostly finely machined by grinding, can now be used no wear show, tin wear is just meant to hcibinatcrial occur, the surface of which also dries with wear must provide that the body coefficient remains constant.

The brakes are now exposed to moisture without affecting them. tiiti ^ t been a hot game when the vehicle is not used for a long time remains, corrosion layers form on the opposing friction surfaces, the can no longer be removed simply by operating the brakes, especially because the rcib material is expressly composed in this way that no counterattack can occur.

Since it is cumbersome, expensive and time-consuming, the brake drum η boring Brake disc «to remove» lic corrosion layers by grinding to remove or sanding, innu has to use simpler means and methods. genes wanted.

Reveal clutches or brakes have become known in which the abdominal materials wholly or partially made of materials with a polishing effect consists'". However, such arrangements have the disadvantage that the remaining material remains permanently in the brake, which is either undesirable Counterattack occurs or the cleaning effect to remove the Corrosion layers are not sufficient.

It is also known that in the case of disc-braked railway wheels the

To lialt the running surface of the Lindes clean through l'utzkliitze, whereby this. can be pressed simultaneously on the wheel running surface by actuating the brake. But even this device is only designed for this and is capable of immediately removing minor soiling, and care must be taken with the device that is constantly remaining on the surface to be cleaned that the counter-attack is not too great. In the case of disc brakes, where it is relatively easy to change the brake shoes, it is now known to temporarily replace the normal brake shoes with such, clean lining when braking at the same time as a abrasive to smoothness and cleaning of the brake disc is effective, the proportion of polishing or grinding agents in the brake lining mixture exceeding 5 wt for the cleaning of slightly corroded or rusted panes is economically necessary , also smeared on the surface and loses its effectiveness

1'the innovation that establishes progress compared to the state of the art consists in the fact that cleaning pads /. the end • to 10 wt. /!

" As metal wool, those made of steel, copper or brass come into question. The special composition depends on the thickness of the corrosion layer addicted.

These clothes, the material of which is attached to a carrier known per se, so that they can easily be built into the brakes in place of normal braces, have been shown to be part of the usual strength different color, for example, with red., marked.
