Vypínací mechanizmus motorovej spojky s vypínacími valcami posobiacimi na teleso vypínacieho' ložiska spojky sa vyznačuje tým, že teleso vypínacieho ložiska spojky je opatřené gulovými lóžkami s kuželovým nábe- hom, do ktorých sa opiera ojnička vedená na opačnom konci gulovým lůžkom, vytvořeným v pieste vypínacieho valca, pričom piest má vo svojej dutině kruhovú drážku, do ktorej zapadá vonkajší nákružok pružného prstence, a ojnička má na povrchu kru- hovú drážku, do ktorej zapadá vnútorný nákružok pružného prstencaThe solution relates to a motor vehicle clutch release mechanism which mainly prevents the transmission of vibrations from the bearing to the piston of the release cylinder. The clutch release mechanism of the clutch roller shut-off roller is characterized in that the clutch release bearing body is provided with cone-shaped spherical flasks into which a connecting rod extending at the opposite end of the ball-shaped bead formed in the clutch cylinder piston is supported. wherein the piston has a circular groove in its cavity, into which the outer collar of the elastic ring fits, and the connecting rod has a circular groove on the surface into which the inner collar of the elastic ring fits
Description
Vynález sa týká vypínacieho mechanizmu motorovej spojky slúžiaceho k ovládaniu motorovej spojky hlavně u motorového vozidla, alebo samohybného pracovného· stroja.BACKGROUND OF THE INVENTION The present invention relates to a clutch release mechanism for operating a clutch mainly in a motor vehicle or a self-propelled working machine.
Je známy vypínací mechanizmus motorovej spojky s vypínacími valcami působiacimi priamo na teleso vypínacieho ložiska spojky, u ktorých sa piest opiera o teleso vypínacieho ložiska spojky. Nedostatkom tohoto riešenia je, že mikropohyby telesa vypínacieho ložiska spojky sposobené rotáciou spojky sa prenášajú priamo na piest a sposobujú otěr v miestach jeho vedenia a v dotykových plochách tesniacej manžety.A clutch release mechanism is known with release cylinders acting directly on the clutch release bearing body in which the piston is supported on the clutch release bearing body. A drawback of this solution is that the micro-movements of the clutch release bearing body caused by the rotation of the clutch are transmitted directly to the piston and cause abrasion at its guide points and in the contact surfaces of the sealing sleeve.
Uvedené nedostatky odstraňuje vypínací mechanizmus motorovej spojky s vypínacími valcami pósobiacimi na teleso vypínacieho ložiska spojky pódia vynálezu, podstatou ktorého je, že teleso vypínacieho ložiska je opatřené guiovými lůžkami s kuželovým nábehom, do ktorých sa opiera ojnička vedená na opačnom konci guiovým ložkom vytvořeným v pieste vypínacieho valca, pričom piest má vo svojej dutině kruhová drážku, do ktorej zapadá vonkajší nákružok pružného prstenca a ojnička má na povrchu kruhová drážku, do ktorej zapadá vnútorný nákružok pružného prstenca.The above-mentioned drawbacks are eliminated by the clutch release mechanism with the release cylinders acting on the clutch release bearing body according to the invention, the principle being that the release bearing body is provided with tapered ball bearings into which the connecting rod is supported at the opposite end. The piston has a circular groove in its cavity into which the outer collar of the elastic ring engages and the connecting rod has a circular groove on its surface into which the inner collar of the elastic ring engages.
Ojnička uložená na oboch koncoch výkyvné v guiových lůžkách neprenáša na piest vypínacieho valca mikropohyby telesa vypínacieho ložiska spojky spůsobené rotáciou spojky. Piest nie je týmito mikropohybmi vykláňaný, netrpí jeho vedenie a nepoškodzuje sa tesniaca manžeta. Pružný prstenec zabraňuje svojvoinému vysunutiu ojničky z guiového lůžka v pieste vypínacieho valca. Přitom neobmedzuje vyklonenie ojničky až do hodnoty kým sa nevyčerpá medzera medzi pružným prstencom a ojničkou v mieste pod vonkajším nákružkom pružného prstenca. Velkost tejto medzery obmedzuje maximálně vyklopenie ojničky voči piestu tak, aby ojnička pri přibližovaní k telesu vypínacieho ložiska spojky bola automaticky navedená do- guiového lůžka jeho kuželovým nábehom. To usnadňuje montáž a zabraňuje náhodnému vypadnutiu ojničky počas prevádzky.The connecting rod mounted on both ends pivotable in ball bearings does not transmit to the piston of the release cylinder the micro-movement of the clutch release bearing body caused by the rotation of the coupling. The piston is not tilted by these micro-movements, does not suffer from its guidance and the sealing sleeve is not damaged. The elastic ring prevents arbitrary ejection of the connecting rod from the ball bearing in the piston of the release cylinder. In doing so, it does not limit the inclination of the connecting rod up to the value until the gap between the elastic ring and the connecting rod has been exhausted at a point below the outer collar of the elastic ring. The size of this gap limits as much as possible the tilting of the connecting rod towards the piston so that the connecting rod is automatically guided by the tapered run-in when approaching the clutch release bearing body. This facilitates assembly and prevents the connecting rod from accidentally falling out during operation.
Vypínací mechanizmus motorovej spojky pódia vynálezu je zobrazený na priloženom obrázku, kde v hornej polovici obrázku je mechanizmus v pracovnej polohe a v dolnej polovici obrázku je mechanizmus v uvol'nenej polohe.The clutch release mechanism of the present invention is shown in the accompanying drawing, wherein the upper half of the drawing is in the working position and the lower half of the drawing is in the released position.
Motorová spojka 1 je vypínaná cez vypínacie ložiskou 2, uložené v telese 3 vypínacieho ložiska. Teleso 3 je opatřené guiovými lůžkami 4 s kuželovým Ěábehom 5. Do lůžka 4 sa opiera ojnička 6 vedená na opačnom konci guiovým lůžkom 7 vytvořeným v pieste 8 vypínacieho' valca 9. Piest 8 má vo svojej dutině kruhová drážku 10, do ktorej zapadá vonkajší nákružok 11 pružného prstenca 12 a ojnička 6 má na povrchu kruhová drážku 13, do ktorej zapadá vnútorný nákružok 14 pružného prstenca 12. V rovině vonkajšieho nákružku 11 pružného prstenca 12. V rovině vonkajšieho nákružku 11 pružného prstenca 12 je medzi pružným prstencom 12 a ojničkou 6 medzera 15 a v rovině vnútorného nákružku 14 pružného prstenca 12 je medzi pružným prstencom 12 a dutinou piesta 8 medzera 16.The clutch 1 is disengaged via a release bearing 2 housed in the release bearing body 3. The housing 3 is provided with ball bearings 4 with a conical groove 5. A connecting rod 6 is supported at the opposite end by a ball bearing 7 formed in the piston 8 of the shut-off cylinder 9. The piston 8 has an annular groove 10 in its cavity. In the plane of the outer collar 11 of the elastic ring 12. In the plane of the outer collar 11 of the elastic ring 12, there is a gap between the elastic ring 12 and the connecting rod 6 in the plane of the outer collar 11 of the elastic ring 12. 15 and in the plane of the inner collar 14 of the elastic ring 12, there is a gap 16 between the elastic ring 12 and the piston cavity 8.
