Description

Stalldon, hyttippningsanordning, ett fordon samt en metod for att styra ett stalldon Uppfinningens omrade Den fareliggande tekniken hanfor sig till ett stalldon, en hyttippningsanordning som innefattar stalldonet, ett fordon som innefattar ett stalldon och/eller en hyttippningsanordning, samt en metod for att styra ett stalldon. FIELD OF THE INVENTION stalldon.

Uppfinningens bakgrund Linjara stalldon anvands idag for att utfora linjarrorelser i valdigt manga applikationer. Ett hydrauliskt linjart stalldon anvander hydraulisk kraft far att astadkomma en mekanisk linjar rorelse. En annan typ av stalldon är pneumatiska linjara stalldon som omvandlar komprimerad luft till en mekanisk linjar rorelse. Ett elektriskt linjart stalldon omvandlar en roterande rarelse fran en motor, exempelvis en la'gvolts DC-motor, till en mekanisk linjar rorelse. Ett linjart stalldon gar det majligt att lyfta, justera, tippa, trycka eller dra tunga eller svaratkomliga faremal bara genom att trycka pa en knapp. Background of the Invention Linear stables are used today to perform linear motions in very many applications. A hydraulically linear stable device uses hydraulic force to achieve a mechanical linear motion. Another type of stable is pneumatic linear stable which converts compressed air into a mechanical linear motion. An electrically linear stable device converts a rotating motion from a motor, for example a low voltage DC motor, into a mechanical linear motion. A linear stable device makes it possible to lift, adjust, tip, push or pull heavy or responsive hazards just by pressing a button.

Ett elektriskt linjart stalldon har vanligtvis en motor, ett vaxelhus och en kolvstang. En skruv, exempelvis en kulskruv eller snackskruv, roteras och rotationen Overfars till en linjar rarelse av kolvstangen. Kolvstangen kan exempelvis lapa i en cylinder eller halje. Hela stalldonet kan omges av ett holje beroende pa applikation och skyddsbehov. An electrically linear stable usually has a motor, a gear housing and a piston rod. A screw, such as a ball screw or snack screw, is rotated and the rotation is transferred to a linear arrangement of the piston rod. The piston rod can, for example, lap in a cylinder or housing. The entire stable can be surrounded by a housing depending on the application and the need for protection.

Ett exempel pa en applikation far ett linjart stalldon är tippning av lastbilshyttar. An example of an application for a linear stable device is tipping of truck cabins.

Det finns ibland ett behov av att kunna tippa hytten for att ge atkomst till de system som sitter monterade under hytten. Det finns olika satt att lam denna funktion pa idag. Exempelvis kan ett stalldon med en hydrauliskt aktuerad kolv vara kopplad till chassit och hytten. Da hytten och chassiet är sammankopplade med ett fjadrande system sá leder detta till att aven tippsystemet maste hantera relativrarelse mellan chassi och hytt. ldag anvands hydraulcylindrar med ett sa. kallat "lost motion" lage, ett lage dar cylinder och kolv kan rora sig relativt 1 varandra. Denna rOrelse ger dock upphov till bade slitage av systemet och oljud i hytten. There is sometimes a need to be able to tip the cab to provide access to the systems that are mounted under the cab. There are different ways to paralyze this feature today. For example, a stable unit with a hydraulically actuated piston can be connected to the chassis and cab. As the cab and the chassis are connected to a resilient system, this also means that the tipping system must also handle relativization between the chassis and the cab. Today, hydraulic cylinders with a saw are used. called "lost motion" lage, a lage where cylinder and piston can move relative to each other. However, this movement gives rise to both wear and tear of the system and noise in the cab.

I EP0485724 Al beskrivs ett hydrauliskt system far att tippa hytten, som kopplas in genom en kombination av translation och rotation. Ett upptagningselement är utformat med ett urtag som passar med ett element pa hytten. ROrelsen mellan elementen kan dock ge upphov till slitage av systemet. EP0485724 A1 describes a hydraulic system for tipping the cab, which is engaged by a combination of translation and rotation. A receiving element is designed with a recess that fits with an element on the cab. The movement between the elements can, however, give rise to wear of the system.

Det är ett syfte med uppfinningen att astadkomma ett stalldon som kan astadkomma en kontrollerad vridning samt linjar rorelse av sin kolvstang, och i synnerhet som mOjliggOr tippning av en fordonshytt. It is an object of the invention to provide a stable device which can achieve a controlled rotation and lines movement of its piston rod, and in particular which makes it possible to tip a vehicle cab.

Sammanfattnind av uppfinninden Enligt en fOrsta aspekt uppnas det ovan beskrivna syftet genom ett stalldon som innefattar en motor, en gangad stang, en mutterenhet, en kolvenhet och ett Motorn är arrangerad att driva den gangade stangen via en vaxellada. Stalldonet innefattar en forsta del pa mutterenheten och en andra del pa holjet som realiserar en forsta styrande funktion for stalldonet, varvid den forsta delen är arrangerad att passa med den andra delen, sa att mutterenheten fOljer en fordefinierad fOrsta bana bestarnd av den fOrsta delen och den andra delen dá den fOrsta och den andra delen är inpassade med varandra och motorn driver den gangade stangen. SUMMARY OF THE INVENTION According to a first aspect, the above-described object is achieved by a stable device comprising a motor, a threaded rod, a nut unit, a piston unit and a The motor is arranged to drive the threaded rod via a gearbox. The stable unit comprises a first part on the nut unit and a second part on the housing which realizes a first controlling function for the stable unit, the first part being arranged to fit with the second part, so that the nut unit follows a predefined first path consisting of the first part and the the second part where the first and the second part are fitted with each other and the motor drives the stepped rod.

Den forsta aspekten ger upphov till ett stalldon som kan utfora en kontrollerad axiell vridning av mutterenheten, och i sin foljd aven kolvenheten. Stalldonet kan alltsa utfora bade en linjar rorelse och en vridning kring en centrumlinje av den gangade stangen. Detta kan vara anvandbart i manga applikationer, och utfors genom att endast aktuera motorn. Den f6rsta styrande funktionen utgor en form av rotationsbegransning mellan kolvenheten och holjet. HOljet kan aven utformas som en cylinder kring mutterenhet och kolvenhet. Den f6rdefinierade fOrsta banan beskriver den rorelse av mutterenhet och/eller kolvenheten som efterfragas. 2 Stalldonet kan innefatta en tredje del pa mutterenheten och en fjdrde del pa kolvenheten som realiserar en lasande funktion for stalldonet . Den tredje delen är arrangerad att passa med den fjdrde delen sã att mutterenheten fOljer en fordefinierad lasbana bestdmd av den tredje delen och den fjdrde delen till ett last lage av kolvenheten till mutterenheten, dá mutterenheten fOljer den fOrdefinierade forsta banan. Genom att ha en lasande funktion kan stalldonet kopplas isar och kopplas ihop, och lasas dá den är ihopkopplad sa att stalldonet bade kan anvandas for att lyfta och dra utan att falla isdr. Den lasande funktionen aktueras genom att endast aktuera motorn. Det lasta laget kan aven kallas formlasning. The first aspect gives rise to a stable device which can perform a controlled axial rotation of the nut unit, and in turn also the piston unit. The stable device can thus perform both a linear movement and a rotation around a center line of the stepped rod. This can be useful in many applications, and is performed by actuating the engine only. The first control function is a form of rotation limitation between the piston unit and the housing. The cover can also be designed as a cylinder around the nut unit and piston unit. The predefined first path describes the movement of the nut unit and / or piston unit requested. The stable device may comprise a third part on the nut unit and a fourth part on the piston unit which realizes a loading function for the stable device. The third part is arranged to fit with the fourth part so that the nut unit follows a predefined load path determined by the third part and the fourth part to a load layer of the piston unit to the nut unit, then the nut unit follows the predefined first path. By having a loading function, the stable device can be connected to ice and connected, and locked when it is connected so that the stable device can both be used to lift and pull without falling ice. The loading function is actuated by only actuating the motor. The loaded layer can also be called form loading.

Stalldonet kan dven innefatta en femte del pa kolvenheten och en sjdtte del pa hOljet som realiserar en andra styrande funktion fOr stalldonet. Den femte delen är arrangerad att passa med den sjdtte delen sâ att kolvenheten fOljer en fOrdefinierad andra bana bestdmd av den femte och den sjdtte delen da. den femte delen och den sjdtte delen ãr inpassade med varandra och motorn driver den gangade stangen. Pa sâ salt uppnas en styrning av kolvenheten sâ att kolvenheten far ett onskat beteende, exempelvis en rotation, eller en lasning i en viss bana. Den andra styrande funktionen kan aven anvandas for att styra kolvenheten sá att ett last lage av kolvenheten till mutterenheten bibehdlls. Den andra styrande funktionen motverkar att kolvenheten roterar med den gdngade stangen, och utgor en form av rotationsbegrdnsning mellan kolvenheten och hOljet. Holjet kring mutterenheten och kolvenheten kan vara i form av en cylinder. The stable device may also comprise a fifth part on the piston unit and a sixth part on the housing which realizes a second controlling function for the stable device. The fifth part is arranged to fit with the sixth part so that the piston unit follows a predefined second path determined by the fifth and the sixth part then. the fifth part and the seventh part are aligned with each other and the motor drives the stepped rod. On such salt, a control of the piston unit is achieved so that the piston unit has a desired behavior, for example a rotation, or a loading in a certain path. The second control function can also be used to control the piston unit so that a load layer of the piston unit to the nut unit is maintained. The second controlling function prevents the piston unit from rotating with the threaded rod, and constitutes a form of rotation restriction between the piston unit and the housing. The housing around the nut unit and the piston unit may be in the form of a cylinder.

Enligt en andra aspekt uppnas syftet atminstone delvis genom en hyttippningsanordning for fordon, som innefattar ett stalldon enligt nagon utforingsfrom som beskrivs hart Stalldonet ar arrangerat att fdstas till fordonets chassi i sin ena dnde och till fordonets hytt i sin andra dnde. Hyttippningsanordningen innefattar vidare en styrenhet och/eller inmatningsenhet som ar arrangerad att aktuera tippningen av hytten. Den andra aspekten ger mOjlighet till att skOta bade sammankoppling av stalldon och hytt, samt tippning av fordonets hytt med en och samma komponent. 3 Anvandandet av ett stalldon, exempelvis ett linjart stalldon, med intern frikoppling styrd av kontrollerad axiell vridning ger mojlighet till att ersatta befintliga hydrauliska anordningar med en elektrisk anordning som har lagre intern friktion och som darmed potentiellt genererar mindre oljud i hytten. According to a second aspect, the object is achieved at least in part by a cab tilting device for vehicles, which comprises a stable device according to any embodiment described herein. The cab tilting device further comprises a control unit and / or input unit which is arranged to actuate the tilting of the cab. The second aspect provides the opportunity to make sure that both the connectors of the stable and the cab are connected, as well as tipping of the vehicle's cab with one and the same component. The use of a stable device, for example a linear stable device, with internal release controlled by controlled axial rotation makes it possible to replace existing hydraulic devices with an electrical device that has lower internal friction and thus potentially generates less noise in the cab.

Enligt en tredje aspekt uppnas syftet atminstone delvis genom ett fordon som innefattar ett stalldon enligt na'gon utfOringsfrom som beskrivs hari, och/eller en hyttippningsanordning. According to a third aspect, the object is achieved at least in part by a vehicle comprising a stable vehicle according to any embodiment described herein, and / or a cab tilting device.

Enligt en fjarde aspekt uppnas syftet atminstone delvis genom en metod for att styra ett stalldon som innefattar en motor, en gangad stang, en mutterenhet, en kolvenhet och ett holje. Metoden innefattar att - placera mutterenheten pa den gangade stangen i hOljet sã att en f6rsta del pa mutterenheten och en passande andra del pa hOljet lOper i varandra; - driva den gangade stangen sâ att mutterenheten fOljer en f6rdefinierad forsta bana som begransas av den fOrsta delen och den andra delen. According to a fourth aspect, the object is achieved at least in part by a method for controlling a stable device which comprises a motor, a running rod, a nut unit, a piston unit and a housing. The method comprises - placing the nut unit on the threaded rod in the housing so that a first part of the nut unit and a suitable second part of the housing run into each other; drive the threaded rod so that the nut assembly follows a predefined first path bounded by the first part and the second part.
