Další nevýhodou známých provedení kotoučových brzd je jej'ich neď°statečné uvozování po odbrzdéní. 1 v případ použití pružných 0-kro-užků mezi oky třmene· tezdy a čely vodících čepů, se po zanesení mezery mezi těmito částmi znemožní žádoucí uvolnovací pohyb.Another disadvantage of the known embodiments of disk brakes is a 'i c h No D ° and tangent st escaping after brake release. 1 in the case of the use of resilient 0-kro narrow-meshed between the class and the name · tezdy faces as says-UP pins after clogging gaps between the parts prevents desirable UVO L p novation bend.
Nevýhodou· známých· konstrukcí je· rovněž · poměrně složitýThe disadvantage of known constructions is also relatively complex
240 190 postup při výměně brzdového obložení. Aby bylo možno radiálně vyjmout destičky s obložením, je nutno odklopit třmen brrdy a k ternu je třeba odjistit a vysunout alespoň jeden vodící čep, jehož vysouvání je při radiálním předpětí v uložení vodících čepů nesnadné.240 190 brake lining replacement procedure. In order to radially remove the lining plates, the brake caliper must be swung open, and at least one guide pin must be unlocked and extended to the tern, which is difficult to pull out in the guide pin housing when radially prestressed.
Cílem, vynálezu je vytvoření konstrukce kotoučové brzdy, u které by nebylo nutné zvýšené dimenzování jednotlivých jejich částí, která by zaru-čovala spolehlivé uvolňování brzdy po odbrzdění a u které by bylo' možno jednoduchým způsobem provádět výměnu brzdového obložení.The objective of the invention is to provide design a disc brake in which it would not need the increased dimensions of the individual refrigerati h CA with T i, kt ER b y guarantee-Coval SPO l e aluminosilicate Mo release ò alkylated d b y d y after releasing and which the brake lining could be replaced in a simple manner.
Podstata'kotoučové brzdy s plovoucím třmenem podle vynálezu spočívá v tom, že vodící čepy jsou uloženy excentricky v Družných pouzdrech uspořádaných otočně v ukládacích' okách třmene brzdy a s' předpětím doléhají na nosné výřezy ramen držáku brzdy, přičemž' ustavovací výřez přesahuje svou vnitřní částí vodící čep.

Zpěttlý pohyb třmene 1 brzdy po odbrždění bude však vyvolán jen odpružením pružných čel 11, 14 a ustaví se tedy jen malá nezbytná vůle pro uvolnění kotouče 2 brzdy, takže zařízení samočinně nastavuje potřebnou vůli mezi brzdovým obložením 25, 28 a kotoučem 2 brzdy.240 190 brake dc original released position. Only when the brake lining 26, 27 is worn more, when the required movement of the brake caliper 1 is greater than the compression of the resilient fronts 13, 14, the guide pins 11, 12 move in the support slots 21 of the legs 22, 21 of the brake holder 24. However, the retracted movement of the brake calliper 1 after releasing will only be caused by the springing of the resilient fronts 11, 14 and therefore only a small necessary clearance for loosening the brake disc 2 will be established so that the device automatically adjusts the necessary clearance between the brake lining 25, 28 and the brake disc 2.
Obvodové síly, působící při brzdění na destičky.s brzdovým obložením 25. 26, jsou zachycovány přímo styčnými plochami 27 do ramen 22. 23 držáku 24 brzdy a nenamáhají proto ani třmen 1 brzdy, ani vodící čepy 11. 12. takže tyto mohou být jen slabě dimenzovány.The peripheral forces exerted on the brake pads 25, 26 during braking are absorbed directly by the contact surfaces 27 into the legs 22, 23 of the brake holder 24 and therefore do not stress either the brake caliper 1 or the guide pins 11. 12. weakly dimensioned.
Nosné výřezy 21 v ramenech 22, 23 držáku 24 brzdy mají s vodícími čepy 11, 12 jen přímkový styk s pružným tlakem, takže zajišíují posuv i při značném zkorodování obou stýkajících se elementů.The support cut-outs 21 in the arms 22, 23 of the brake holder 24 have only a direct contact with the elastic pressure with the guide pins 11, 12, so that they ensure displacement even if the two contacting elements are corroded significantly.
Obzvláště snadná a rychlá je pak výměna brzdového obložení 2£, 26 podle vynálezu. Vodící čepy 11., 12 se zatlačí proti pružným čelům 13. 14 a otočí <b 1SO°. Zatlačením vodících čepů 11, 12 se vysunou kolíky 17, 18 z drážek 19.20 a jejich otočením o 180° dojde к jejich oddálení mimo nosné výřezy 21. Třmen X brzdy lze pak i s vodícími čepy 11. 12, a destičkami s brzdovým obložením 25« 26 vyjmout z držáku 24 brzdy radiálním směrem. Ve vyjmutém stavu, otočením vodících čepů 11, 12 do původní polohy, uvolní se pak destičky β brzdovým obložením 25.» 26, takže je lze vyjmout a nahradit novými. Zpětná montáž třmene X, brzdy a destičkami do držáku 24 brzdy se pak provede obdobně snadným způsobem.The replacement of the brake pads 26, 26 according to the invention is particularly easy and quick.
