Abstract
Sklopný volant je určený pre motorové vozidlá, hlavně pre polnohospodárske traktory. Očelom riešenia je umožnenie sklopenia volantu do najvhodnéjSej polohy. V pracovnej polohe je volant aretovaný západkou zapadajúcou do ozubeného segmentu. Západka je samosvorná, čo zvyšuje bezpečnost funkcie zariadenia.The folding steering wheel is intended for motor vehicles, mainly for agricultural tractors. The purpose of the solution is to allow the steering wheel to be folded into the most suitable position. In the working position, the steering wheel is locked by a latch that fits into the toothed segment. The latch is self-locking, which increases the safety of the device's function.
Description
Vynález sa týká sklopného volantu motorových vozidiel, u ktorého sa rieši spůsob uloženia sklopného náboja volantu a spůsob jeho aretácie.BACKGROUND OF THE INVENTION The present invention relates to a folding steering wheel of a motor vehicle, in which a method of receiving the folding hub of a steering wheel and a method of locking it is provided.
Sú známe konštrukcie sklopného volantu s ozubeným segmentom do ktorého zapadá západka. Nedostatkom tohoto riešenia je, že pri roalom rozmere segmentu je potřebná velká sila pružiny na pritláčanie západky, aby pri zatažení volantu nedošlo k jej vytlačeniu zo záběru. Tento nadostatok odstraňuje sklopný volant so zváčšeným ramenom ozubeného segmenta. Jeho nedostatkom sú velké nároky na priestor.There are known constructions of a tilting steering wheel with a toothed segment into which the latch engages. The disadvantage of this solution is that with the long dimension of the segment a large spring force is required to press the latch so that it is not disengaged when the steering wheel is pulled. This excess removes the tilting steering wheel with the enlarged gear arm. Its disadvantage is the high demands on space.
Uvedené nedostatky odstraňuje sklopný volant podlá vynálezu podstatou ktorého je, že náboj volantu je otočný okolo dvoch výklopných čapov, zakotvených v konzolách vystupujúcich nad ovládací panel a v pracovnej polohe je aretovaný západkou otáčajúoou sa na hriadeli západky, uloženom pod ovládacím panelom rovnoběžně s výklopnými čapmi. Náboj volantu je opatřený ozubeným segmentom, s nesúmernými zubami, pričom osa hriadela západky leží medzi kolmicami vedenými na boky zubov.According to the invention, the steering wheel hub is rotatable about two hinged pins anchored in brackets extending above the control panel and is locked in a working position by a pawl rotating on a latch shaft disposed below the control panel parallel to the hinged pins. The steering wheel hub is provided with a toothed segment with asymmetrical teeth, the pawl shaft axis lying between perpendiculars directed to the tooth flanks.
Ůloženie výklopných čapov nad ovládacím panelom umožňuje umiestniť ozubený segment a hriadel západky pod ovládacím panelom v jeho blízkosti bez nárokov na výšku ovládaoieho panelu. Umiestnenie hriadela západky do priestoru medzi kolmice vedené na nesúmerne skloněné boky tej zubovej medzery v ktorej je zasunutý zub západky, umožňuje vytvořit samosvórnú západku pre oba směry vykláňania volantu. Tým je zabezpečená aretácia sklopného volantu pri malých nárokoch na priestor a na silu vratnej pružiny pri automatickom vymedzovaní vůle v západke. Dvojdielna západka podopiera zub na dvoch stranách, čím sa znižuje jeho namáhanie. To umožňuje zmenšit rozteč ozubenia a docielit jemnejšie delenie.The arrangement of the hinge pins above the control panel makes it possible to locate the toothed segment and the latch shafts below the control panel near the control panel without claiming the height of the control panel. Placing the pawl shaft in the space between the perpendiculars directed to the asymmetrically sloping sides of the tooth gap in which the pawl tooth is inserted makes it possible to create a self-locking pawl for both steering wheel tilt directions. This ensures that the folding steering wheel is locked at low space requirements and the force of the return spring while automatically adjusting the latch clearance. The two-piece latch supports the tooth on two sides, reducing stress. This makes it possible to reduce the tooth pitch and achieve a finer separation.

Sklopný náboj _1 je otočný okolo dvoch výklopných čapov 2 v konzolách 2 vystupujúcich nad ovládací panel 4. V pracovnej polohe je náboj 1. aretovaný západkou ji otáčajúcou sa na hriadeli uloženom pod ovládacím panelom 4 rovnoběžně s výklopnými čapmi 2. Sklopný náboj _1 je opatřený ozubeným segmentom 7_, ktorého zubové medzery majú nesúmerne skloněné boky ji.The tilt hub 1 is rotatable about two tilt pins 2 in the brackets 2 extending above the control panel 4. In the working position, the hub 1 is latched by a latch rotating on a shaft mounted below the control panel 4 parallel to the tilt pins 2. a segment 7 whose tooth gaps have disproportionately inclined sides thereof.
Os 9 hriadela jj západky ji leží medzi kolmicami 10 vedenými na boky ji tej zubovej medzery, v ktorej je zasunutý ozub 11 západky J3. Ak os 9 leži medzi kolmicami 10 súmerne, potom normálně sily 12 působiace medzi zubom 11 a bokmi ji zubovej medzery vytvárajú k ose 9 rovnaké klopné momenty snažiace sa západku vyklopit zo záběru. Ak je klopný moment sil 10 na ramenách 13 menši ako trecie momenty působiace na západku, je západka samosvorná pre obidva směry zaťaženia sklopného volantu.The pawl shaft axis 9 is located between the perpendiculars 10 extending to the sides of the tooth gap in which the pawl tooth 11 is engaged. If the axis 9 lies symmetrically between the perpendiculars 10, then normally the forces 12 acting between the tooth 11 and the sides of the tooth gap create the same tilting moments to the axis 9 trying to pivot the latch out of engagement. If the tilting moment of the forces 10 on the arms 13 is less than the frictional moments acting on the latch, the latch is self-locking for both directions of loading of the tilting steering wheel.
