Description
141941141941
Den foreliggende opfindelse angår en sneplov af den art, der er angivet i indledningen til krav 1, dvs. med et skrabeblad, som normalt er beregnet til at befæstiges til et ophængsbeslag ved forenden af en lastvogn og til ved 5 dennes hjælp at fremføres langs en vejbane for mere eller mindre vidtgående renskrabning af denne. Ved egentlig skra-beberøring fremkaldt f.eks. ved vægten af skrabebladet vil der fremkomme et kraftigt slid på både skrabebladet og vejoverfladen, og det tilstræbes derfor at montere 10 skrabebladet med en frigangshøjde på et par mm. Da det vognchassis, hvortil skrabebladet befæstiges, ikke kan påregnes at ligge fuldkommen stabilt under kørslen, er det nødvendigt at lade skrabebladet være selvstændigt støttet mod vejbanen ved hjælp af f.eks. glidesko eller støtte-15 hjul, der er monteret på bagsiden af skrabebladet på en sådan måde, at de virker som lokale afstandsholdere mellem skrabebladets underkant og vejoverfladen, idet skrabebladet er således forbundet med vognchassis1 et, at det ikke er bundet til at følge chassis'ets lodrette bevægelser.The present invention relates to a snow plow of the kind set forth in the preamble of claim 1, i. with a scraper blade, which is usually intended to be attached to a suspension bracket at the front of a truck and to be conveyed at its aid along a roadway for more or less extensive scraping thereof. In actual scratching touch, e.g. due to the weight of the scraper blade, a sharp wear will occur on both the scraper blade and the road surface, and therefore it is sought to mount the scraper blade with a clearance height of a few mm. Since the carriage chassis to which the scraper blade is attached cannot be expected to be perfectly stable while driving, it is necessary to allow the scraper blade to be independently supported against the roadway by means of e.g. sliding shoes or support wheels mounted on the rear of the scraper blade in such a way that they act as local spacers between the bottom edge of the scraper blade and the road surface, the scraper blade being thus connected to the carriage chassis1 so that it is not bound to follow the chassis. etch vertical movements.
20 Navnlig ved brug af støttehjul monteret i svingkonsoller opnås en vejstøtte med lav friktion også ved kørsel gennem kurver, og da hjulene er beliggende umiddelbart bag skrabebladet, vil dette stort set følge de lokale højdevariationer, som forekommer i vejbanen, under fremføringen langs 25 denne.20 In particular, when using support wheels mounted in swing brackets, low friction road support is also obtained when driving through curves, and since the wheels are located immediately behind the scraper blade, this will largely follow the local elevation variations that occur in the roadway during feed along it.
Det kan dog alligevel konstateres, at højdejusteringen ikke er tilstrækkelig nøjagtig, da denne ikke foregår på selve skrabestedet, men netop alt efter hjulplaceringen et stykke bag dette, hvorved det ofte forekommer, at skrabe vinderkan ten 30 lokalt enten hæves højere end ønsket eller sænkes til direkte berøring med den faste vejoverflade, således at skrab-ningen bliver uregelmæssig og forbundet med et betragteligt slid på både vejbane og skrabeblad. Denne virkning forstærkes antagelig på grund af skrabebladets inerti, idet bladet 35 dels vil reagere med en ringe forsinkelse på en lodret bevægelse af støttehjulet og dels vil søge at fortsætte en 141941 2 påbegyndt bevægelse efter at den tilhørende forskydning af støttehjulet er ophørt. Under visse kørselsbetingelser kan der herved opstå kraftige rystelser i skrabebladet. En jævnere gang kunne tilstræbes opnået med en form for af-5 fjedring, men for at være effektivt kan et sådant arrangement meget vel indebære, at skrabebladets reaktionstid m.h.t. højdebevægelserne gøres utilladeligt lang.However, it can nevertheless be found that the height adjustment is not sufficiently accurate, since it does not take place at the scraping site itself, but precisely depending on the wheel placement a distance behind it, whereby it is often found that the scrap winch 30 locally is either raised higher than desired or lowered to direct contact with the fixed road surface, so that the scraping becomes irregular and associated with considerable wear on both roadway and scraper blades. This effect is presumably enhanced by the inertia of the scraper blade, the blade 35 partly responding with a slight delay to a vertical movement of the support wheel and partly seeking to continue a movement begun after the associated displacement of the support wheel has ceased. Under certain driving conditions, severe shaking may occur in the scraper blade. A smoother time could be achieved with some kind of suspension, but to be effective such an arrangement may very well imply that the reaction time of the scraper blade may be affected. the altitude movements are made impossibly long.
Opfindelsen har til formål at angive et skraberedskab af den nævnte art, som generelt kan fremføres med god evne 10 til at følge de lokale højdevariationer i vejbanen uden større tendens til at udføre vertikale rystelser.The invention has for its object to provide a scraper preparedness of the kind mentioned, which can generally be advanced with good ability 10 to follow the local elevation variations in the roadway without a great tendency to carry out vertical shaking.
Dette opnås ifølge opfindelsen ved, at sneploven er indrettet som angivet i den kendetegnende del af krav 1. Ved denne indretning, hvor hvert af de kendte enkelte støtte-15 hjul er erstattet med et tandemhjulpar i en vippekonsol, opnås at forbindelsesområdet mellem støttehjulkonsollen og skrabebladet ikke umiddelbart vil følge højdebevægelserne af et enkelt støttehjul, da konsollen ved begyndende og ved afsluttende højdebevægelse af et af hjulene vil svin-20 ges omkring aksen for det andet hjul, hvorved nævnte mellemliggende forbindelsesområde vil udføre en reduceret højdebevægelse eller en højdebevægelse med reduceret hastighed. Resultatet er, at skrabebladet fremføres forholdsvis roligt hen over lokale ujævnheder, idet vippekonsol-25 len vil tendere til at skabe en udjævnet eller dæmpet begyndelse og afslutning på enhver højdebevægelse af skrabebladet, vel at mærke samtidigt med, at det er vejbanen selv og ikke uvedkommende dæmpningsorganer, som styrer bevægelserne. Heri ligger, at skrabebladet fortsat reagerer sær-30 deles kontant på forekommende niveauændringer i vejbanen, dvs. der opnås generelt en særdeles god skrabevirkning med et minimum af slid og med en udjævnende virkning ved skråbning over koncentrerede ujævnheder.This is achieved according to the invention in that the snow plow is arranged as defined in the characterizing part of claim 1. In this device, where each of the known individual support wheels is replaced with a tandem wheel pair in a rocker bracket, the connection area between the support wheel bracket and the scraper blade is obtained. will not immediately follow the elevation movements of a single support wheel, since at the beginning and at the final elevation movement of one of the wheels, the bracket will pivot about the axis of the other wheel, whereby said intermediate connecting region will perform a reduced elevation movement or a reduced velocity elevation movement. The result is that the scraper blade is moved relatively calmly over local bumps, as the tilt bracket will tend to create a smoothed or damped beginning and end of any height movement of the scraper blade, while noting that it is the roadway itself and not unauthorized. damping means which control the movements. Herein lies that the scraper blade continues to respond very cash in part to any level changes in the roadway, ie. generally a very good scraping effect is obtained with a minimum of wear and with a smoothing effect when sloping over concentrated irregularities.
Den nævnte virkning bliver mere udpræget, jo tættere hjul-35 konsollens vippeakse ligger ved forbindelseslinien mellem i 3 141941 centrerne for de tilhørende tandemhjul, og hjulkonsollen er derfor hensigtsmæssigt udformet som angivet i krav 2.Said effect becomes more pronounced the closer the tilting axis of the wheel bracket lies at the connecting line between the centers of the associated tandem wheels, and the wheel bracket is therefore suitably designed as claimed in claim 2.
Ved opfindelsen har man iøvrigt mulighed for, jfr. krav 3, at anbringe det ene hjul betydeligt nærmere ved skrabebla-5 dets bagside end det hjul, der skal sørge for at konsollen automatisk drejes i overensstemmelse med køreretningen, hvorved en del af den rullende understøtning på fordelagtig måde kan anbringes tættere ved skrabebladet end ved brug af et enkelt hjul, hvorved højdejusteringen bliver endnu 10 mere nøjagtig.In addition, the invention has the possibility, cf. Claim 3, affixing one wheel substantially closer to the rear of the scraper blade than the wheel to ensure that the bracket is automatically rotated in accordance with the direction of travel, whereby a portion of the rolling support can advantageously be placed closer to the scraper blade than at using a single wheel, making the height adjustment even 10 more accurate.
Det har iøvrigt vist sig, at opfindelsen desuden indebærer den fordel, at støttehjulene viser en meget ringe tendens til under kørslen at udføre svingninger i tværgående vandret retning, hvilket ellers er et betydeligt og velkendt 15 problem ved brug af de kendte svingkonsolhjul.Moreover, it has been found that the invention also has the advantage that the support wheels show a very slight tendency during the driving to execute oscillations in the transverse horizontal direction, which is otherwise a significant and well-known problem with the use of the known swing console wheels.
Opfindelsen forklares i det følgende nærmere i forbindelse med tegningen, på hvilken, fig. 1 er et ovenbillede af en sneplov ifølge opfindelsen, fig. 2 et perspektivisk billede af den ene ende af sneplo-20 ven set bagfra, og fig. 3 et sidebillede af sneploven.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail in connection with the drawing, in which: FIG. 1 is a top view of a snow plow according to the invention; FIG. 2 is a rear perspective view of one end of the snow plow; and FIG. 3 is a side view of the snow plow.
Den i fig. 1 viste sneplov er som helhed betegnet med 6.The FIG. 1 snow plow as a whole is denoted by 6.
Den består af et skrabeblad 8, der ved sin bagside er forsynet med bagudragende hjulholdebeslag 38 nær de modstående 25 ydre ender af skrabebladet. Dette er på sædvanlig, ikke nærmere vist måde beregnet til at forbindes med forenden af et skubbende køretøj, eksempelvis med den i fig. 1 viste skråstilling i forhold til køreretningen.It consists of a scraper blade 8, which at its rear is provided with rearwardly extending wheel retaining bracket 38 near the opposite 25 outer ends of the scraper blade. This is intended, in a conventional manner, not shown, to be connected to the front end of a pushing vehicle, for example with the one shown in FIG. 1 in relation to the direction of travel.
Som også vist i fig. 2 og 3 har skrabebladet 8 ved hver ende 30 af sin bagside er svinghængsel 36 for en bagudragende bærearm 22, der er forbundet med en støttehjulkonsol 24, hvorved bladet 8 er støttet mod vejbanen ved hjælp af svingbare 4 U1961 hjul, der dels er effektive uanset skrabebladets vinkelstilling og dels yder en lavfriktionsunderstøtning også ved kørsel gennem kurver. Ifald konsollerne 24 hver indeholder et enkelt hjul eller sågar et par koaksialt anbrag-5 te tvillingehjul, vil det således beskrevne og i fig. 1 viste arrangement tilhøre den kendte teknik.As also shown in FIG. 2 and 3, the scraper blade 8 at each end 30 of its rear side is pivot hinge 36 for a rearward projecting support arm 22 which is connected to a support wheel bracket 24, the blade 8 being supported against the roadway by pivotal wheels 4 which are partly effective regardless of the angular position of the scraper blade and partly provides a low friction support also when driving through curves. If the brackets 24 each contain a single wheel or even a pair of coaxially arranged twin wheels, it will thus be described and shown in FIG. 1 of the prior art.
Som vist er imidlertid sneploven ifølge opfindelsen forsynet med to efter hinanden anbragte støttehjul 26 og 28 i hver hjulkonsol 24. Hjulkonsollen 24 er lejret svingbart 10 omkring en tværtap 30 anbragt vandret gennem den nedre ende af en lodret tap 32, der er fast nedragende fra den ydre ende af bærearmen 22. Ved sin forreste ende er bærearmen 22 udformet med en lodret drejetap 34, der optages i en lejebøsning 36, der udgør det nævnte svinghængsel og selv 15 er højdeindstilleligt fastholdt i et holdebeslag 38. Konsollen 24 vil herved kunne svinge i vandret plan ganske som hvis den på sædvanlig måde kun indeholdt et enkelt hjul.However, as shown, the snow plow according to the invention is provided with two consecutive support wheels 26 and 28 in each wheel bracket 24. The wheel bracket 24 is pivotally mounted 10 about a transverse pin 30 arranged horizontally through the lower end of a vertical pin 32 which is firmly projected from the outer end of support arm 22. At its front end, support arm 22 is formed with a vertical pivot 34 which is accommodated in a bearing sleeve 36 constituting said pivot hinge and itself 15 is height adjustably secured in a holding bracket 38. The bracket 24 will thereby be able to pivot in horizontal plane quite as if it usually contained only a single wheel.
Imidlertid vil hele konsollen 24 under kørslen yderligere kunne vippe i lodret plan omkring tværtappen 30, hvorved 20 f.eks. en isoleret løftning af det forreste hjul 28 vil resultere i, at konsollen svinges op omkring aksen for hjulet 26, og at bærearmen 22 og dermed skrabebladet 8 kun løftes i mindre grad. løvrigt vil hovedvirkningerne af dette arrangement være som allerede omtalt foran.However, while driving, the entire console 24 will be able to tilt further vertically about the transverse pin 30, whereby 20 e.g. an isolated lifting of the front wheel 28 will result in the bracket being pivoted up around the axis of the wheel 26 and raising the support arm 22 and thus the scraper blade 8 to a lesser extent. the main effects of this arrangement will be as already mentioned above.
25 For opnåelse af de bedste virkninger er det fundet formålstjenligt at lade tværtappen 30 være lokaliseret en smule nærmere ved det forreste hjul 28 end ved det bageste hjul 26, ligesom tappen ikke bør ligge væsentligt højere end i ; hjulenes oversideplan. Fortrinsvis - som vist i fig. 3 -30 bør centrum af det forreste hjul 28 være beliggende lidt bagved den lodrette svingakse for drejetappen 34, idet dette synes at stabilisere hjulkonsollen imod svingninger i vandret plan under kørslen.In order to obtain the best effects, it has been found expedient to allow the cross pin 30 to be located slightly closer to the front wheel 28 than to the rear wheel 26, just as the pin should not be substantially higher than in; the upper surface of the wheels. Preferably - as shown in FIG. 3 to 30, the center of the front wheel 28 should be located slightly behind the vertical pivot axis of the pivot 34, as this appears to stabilize the wheel bracket against horizontal plane pivots while driving.
Ved afprøvninger af en sneplov ifølge opfindelsen har det i 141941 5 vist sig, at der opnås en yderst effektiv og jævn skrabe-virkning, et minimalt skrabeslid, en rolig gang af ploven og en bemærkelsesværdig god styreevne og retningsstabilitet af det skubbende køretøj.In tests of a snow plow according to the invention, it has been found in 141941 that an extremely efficient and even scraping effect, a minimal scratching wear, a smooth plowing and a remarkable good steering and directional stability of the pushing vehicle.
