Description

Sjalvgiende midjestyrd vagvalt med svangbar valsenhet Uppfinningen avser utformningen av sjalvgaende midjestyrda vagvaltar vars karosser är uppdelad i en frdmre och bakre del. En primar valsenhet är 5 fast forbunden till den ena karossdelen och en sekundar valsenhet är svangbart forbunden till den andra karossen. Den framre och bakre karossen är svangbart och tiltbart forbundna av en midjeled. Vagvalten styrs vanligtvis genom att midjeleden medger svangrorelser mellan karossema runt en vertikal svangaxel ("midjestyming"). Altemativt kan 10 vagvalten dessutom styras genom att den sekundara valsenhetens forbindning medger svangrorelser mellan enheten och karossen runt ytterligare en vertikal svangaxel ("offset styming"). Vagvalten innefattar aven en forarplattform och en motorgondol fOrbundna till karossema. Enligt uppfinningen är valsenhetema, fOrarplattformen och motorgondolen 15 arrangerade pa ett sätt som medger att motorgondelen utformas rymligare. Den rymligare motorgondolen erfordras for att ge plats at utrustning for efterbehandling av framdrivningsmotoms emissioner ("EAT-utrustning"). Motorgondolen är utformad rymligare utan att detta medfor fOrsamrad manovrerbarhet for vagvaiten eller okning av dess totala langd. The invention relates to the design of self-propelled articulated rollers whose bodies are divided into a front and rear part. A primary roller unit is fixedly connected to one body part and a secondary roller unit is pivotally connected to the other body. The front and rear bodies are pivotally and tiltably connected by a waist joint. The rocker roll is usually controlled by the waist joint allowing arch movements between the bodies around a vertical turn axis ("waist control"). Alternatively, the rocker roller can also be controlled by allowing the connection of the secondary roller unit to allow pivotal movements between the unit and the body around a further vertical pivot axis ("offset control"). The carriage also includes a driver's platform and a motor gondola connected to the bodies. According to the invention, the roller units, the feed platform and the motor gondola 15 are arranged in a manner which allows the motor gondola part to be designed more spaciously. The more spacious engine gondola is required to accommodate propulsion engine after-treatment equipment ("EAT equipment"). The motor gondola is designed more spaciously without this leading to compromised maneuverability of the cradle or an increase in its total length.

I patentskriften med publiceringsnummer SE502269 beskrivs en kand sjalvgaende midjestyrd vagvait 1 (visas i foreliggande ansokans Figur 1). Vagvalten 1 innefattar en framre 2 och bakre 3 kaross. Karossema 2,3 är svangbart och tiltbart forbundna av en midjeled 4. Vdgvalten 1 styrs primart genom att midjeleden 4 medger svangrorelser mellan karossema 2,3 runt ledens 4 vertikala svangaxel. Vagvalten 1 innefattar aven en forarplattform 5, en motorgondol 6 samt en primdr 7 och en sekundar 8 valsenhet. Varje valsenhet 7,8 innefattar i sin tur roterbart forbundna valsar. Den primara valsenheten 7 är fast forbunden till den framre karossen 2 och den sekunddra valsenheten 8 är svangbart forbunden till den bakre karossen 3. Den sekundara valsenhetens 8 svangbarhet är anordnad runt en vertikal svangaxel. Motorgondolen 6 är utformad med en utbredning i vagvaltens 1 ldngdriktning som natt och jamt ger tillrackligt utrymme for vagvaltens 1 framdrivningsmotor 9. Motorgondolens 6 utbredning medger samtidigt erforderliga styrutslag for den sekundara valsenheten 8. Problem uppstar ndr motorgondolen 6 behover utformas storm for att rymma.en EATutrustning. Den nodvandiga utvidgningen i vagvaltens 1 langdled av motorgondolen 6 innebar en reducering av styrutslagen om vagvaltens 1 totallangd skall forbli ofordndrad. 40 Patentskriften DD229449 visar en midjestyrd vdgvalt med fOrarplattformen, motorgondolen och den primdra valsenheten forbundna till vagvaltens bakre kaross. Vd.kens sekunddra valsenhet är svangbart 1 forbunden till den framre karossen. En utvidgning av motorgondolen i vdltens langdled, for att ge utrymme at EAT-utrustning, skulle darfor inte behova paverka den sekundara valsenhetens svangbarhet. Forlangningen av motorgonden skulle dock aka valtens totallangd. Forlangningen skulle dessutom forskjuta midjeledens svangaxel fran en onskad position mitt emellan valsenheternas valsar. Forskjutningen skulle forsamra valtens manovrerbarhet eftersom valsarna skulle ffilja olika spar under midjestyrning. 10 Syftet med foreliggande uppfinning är att erhalla en midjestyrd vagvalt med en rymligare motorgondol an tidigare samt med bibehallen totallangd och manovrerbarhet. Enligt uppfinningen uppnas syftet genom ett innovativt basarrangemang ddr vagvaltens forarplattform och svangbara sekundara valsenhet är fOrbundna till samma kaross. The patent specification with publication number SE502269 describes a bachelor self-guided articulated vagvait 1 (shown in Figure 1 of the present application). The roll bar 1 comprises a front 2 and rear 3 body. The bodies 2,3 are pivotally and tiltably connected by a waist joint 4. The boom 1 is primarily controlled by the waist joint 4 allowing pivotal movements between the bodies 2,3 around the vertical pivot axis of the joint 4. The carriage roller 1 also comprises a driver platform 5, a motor gondola 6 and a primer 7 and a secondary roller unit. Each roller unit 7,8 in turn comprises rotatably connected rollers. The primary roller unit 7 is fixedly connected to the front body 2 and the secondary roller unit 8 is pivotally connected to the rear body 3. The pivotability of the secondary roller unit 8 is arranged around a vertical pivot axis. The motor gondola 6 is designed with a spread in the longitudinal direction of the rocker 1 which at night and at the same time provides sufficient space for the rocker 1's propulsion motor 9. The motor gondola 6's extension also allows the required steering deflection for the secondary roller unit 8. Problems arise EAT equipment. The necessary expansion in the longitudinal direction of the rocking roller 1 of the motor gondola 6 meant a reduction of the steering deflection if the total length of the rocking roller 1 is to remain unchanged. Patent specification DD229449 shows a articulated wall roller with the driver platform, the motor gondola and the primary roller unit connected to the rear body of the rocker roller. The CEO's secondary roller unit is pivotally connected to the front body. An extension of the motor gondola in the longitudinal direction of the roller, in order to allow space for EAT equipment, would therefore not have to affect the pivotability of the secondary roller unit. However, the demand for the motor gondola should aka the total length of the roller. The extension would also displace the pivot axis of the articulated joint from a desired position midway between the rollers of the roller units. The displacement would impair the maneuverability of the roller as the rollers would fill different grooves during articulation. The object of the present invention is to obtain a articulated crankshaft with a more spacious motor gondola than before and with the maintained overall length and maneuverability. According to the invention, the object is achieved by an innovative base arrangement in which the driver's driver's platform and pivotable secondary roller unit are connected to the same body.

Figuren 1 visar teknikens standpunkt nar det galler sjalvgaende midjestyrda vagvaltar med svangbara valsenheter. Figure 1 shows the state of the art when it comes to self-guided articulated rockers with pivoting roller units.

Foreliggande uppfinning kommer att narmare beskrivas med hjalp av de bifogade figurerna 2-4. Figuren 2 visar en vy fran sidan av ett fcirsta och ffiredraget utfOringsexempel pa en sjalvgaende midjestyrd vagvalt med en svangbar valsenhet. Figur 3 visar vagvalten frail figur 2 uppifran under en svangmanover. Figuren 4 visar ett andra utforingsexempel pa vagvalten i en vy frail sidan. The present invention will be further described with the aid of the accompanying Figures 2-4. Figure 2 shows a side view of a first and preferred embodiment of an independent articulated crankshaft with a pivotable roller unit. Figure 3 shows the rock roller from figure 2 from above during a turn maneuver. Figure 4 shows a second embodiment of the rock roller in a view from the side.

Vagvalten 1 i Figur 2 innefattar en framre 2 och en bakre 3 kaross. Benamningarna "framre och bakre kaross" syftar pa den kaross-del som är belagen framst respektive bakerst i vagvalten 1. Vad som är fram och bak pa en vagvalt är inte alltid helt latt att faststalla eftersom vagvaltar är anpassad for all framforas bade framlanges och baklanges. Lagkrav tvingar dock vagvaltstillverkare all definiera vad som är fram och bak. Darfor aterfinns anordningar (ej visade i figuren) for all alstra trafikbelysning med vitt sken, i vagvaltens 1 framatriktning, pa den framre karossen 2 och anordningar for att alstra rott sken, i vagvaltens 1 bakatriktning, pa den bakre karossen 3. Ett annat kanneteeken är att tillverkaren anordnat ett s.k. "back-alarm" till all ljuda nar valten framfors i den riktning som definierats som bakat. Vagvalten 1 innefattar aven en forarplattform 5, en motorgondol 6, en primal- valsenhet 7, en sekundar valsenhet 8, en midjeled 4, en framdrivningsmotor 9 och en EAT-utrustning 10. Forarplattformen 5 är det utrymme dar vagvaltens 1 forare befinner sig nar vagvalten 1 är i drift. Forarplattformen 5 innefattar en hytt for att skydda feraren, en ffirarstol samt manoverorgan ffir att fOraren t.ex. skall kunna paverka vagvalten 1 till att svanga med midjestyrning och/eller offset-styrning. Det är aven mojligt att utforma forarplattformen 5 utan hytt och att istallet 2 skydda foraren med en stortbage, forsedd med vaderskydd. Forarstolen och manoverorganen är anordnade vridbara for att erhalla god ergonomi for foraren i bada fardriktningarna. Det är aven mojligt att istallet anordna forarplattformen 5 vridbart fOrbunden fOr att uppna god forarergonomi. The carriage roll 1 in Figure 2 comprises a front 2 and a rear 3 body. The terms "front and rear body" refer to the body part that is coated at the front and rear of the rocker 1. The front and rear of a rocker is not always easy to determine because rockers are adapted for all front and rear wheels. . Legal requirements, however, force waddle manufacturers to define what is front and rear. Therefore, there are devices (not shown in the figure) for generating traffic light with white light, in the forward direction of the rocker 1, on the front body 2 and devices for generating red light, in the rear direction of the rocker 1, on the rear body 3. Another pitcher is that the manufacturer has arranged a so-called "back-alarm" to all sounds when the selection is advanced in the direction defined as baked. The carriage roller 1 also comprises a driver platform 5, a motor gondola 6, a primal roller unit 7, a secondary roller unit 8, a waist joint 4, a propulsion motor 9 and an EAT equipment 10. The driver platform 5 is the space where the driver of the carriage roller 1 is located when the carriage roller 1 is in operation. The driver platform 5 comprises a cab for protecting the driver, a driver's seat and operating means for the driver e.g. shall be able to influence the rocker roller 1 to swing with waist control and / or offset control. It is also possible to design the driver platform 5 without a cab and that instead 2 protect the driver with a large bag, provided with water protection. The driver's seat and the maneuvering means are arranged rotatably in order to obtain good ergonomics for the driver in both directions of travel. It is also possible to instead arrange the driver platform 5 rotatably connected in order to achieve good driver ergonomics.

Den sekundara valsenheten 8 är svangbart forbunden till samma kaross som forarplattformen 5. Forarplattformen 5 och den sekundara valsenheten 8 är forbundna till den framre karossen 2. Den primara valsenheten 7 är fast forbunden till den bakre karossen 3. Foraren far god overblick over den sekundara valsens 8 svangrorelser tack vare arrangemanget. 10 Motorgondolen 6 är forbunden till den kaross 2,3 som inte är forbunden med forarplattformen 5 och den sekundara valsenheten 8, d.v.s. till den bakre karossen 3. Motorgondolen 6 är utformad sâ att den inrymmer bade vagvaltens 1 framdrivningsmotor 9 och EAT-utrustningen 10. Utformningen är moj hg tack vare att den fast fOrbundna primara valsenheten 7 inte haver nagot utrymme for styrutslag. Det frigjorda utrymmet är istallet utnyttjat for att utforma motorgondolen 6 rymligare. Vagvaltens 1 totallangd är oforandrad jamfOrt med vagvalten i figur 1. Midjeleden 4 är arrangerad pa samma sat och har samma funktioner som den midjeled som beskrivits i anslutning till figur 1. The secondary roller unit 8 is pivotally connected to the same body as the driver platform 5. The driver platform 5 and the secondary roller unit 8 are connected to the front body 2. The primary roller unit 7 is fixedly connected to the rear body 3. The driver has a good overview of the secondary roller 8 pregnancies thanks to the event. The motor gondola 6 is connected to the body 2,3 which is not connected to the driver platform 5 and the secondary roller unit 8, i.e. to the rear body 3. The motor gondola 6 is designed to accommodate both the drive motor 9 of the rocker roller 1 and the EAT equipment 10. The design is very high due to the fact that the fixedly connected primary roller unit 7 does not have any space for steering deflection. The free space is instead used to make the motor gondola 6 more spacious. The total length of the rocker roller 1 is unchanged compared to the rocker roller in figure 1. The waist joint 4 is arranged in the same way and has the same functions as the waist joint described in connection with figure 1.

Figur 3 visar vagvalten 1 under en kombinerad svangmanover. Vagvaltens 1 framre 2 och bakre 3 kaross har paverkats till en svangrorelse runt midjeledens 4 vertikala svangaxel och har intaget den vinklade position som visas i figuren. Den svangbara sekundara valsenheten 8 har samtidigt paverkats till en svangrorelse runt sin vertikal svangaxel som upphaver effekten av karossernas 2,3 svangrorelse. Svangmanovern benamns "offsetstyrning" och resulterar i att vagvalten 1 framfors rakt fram (eller rakt bakat). Offset-styrningen okar vagvaltens 1 arbetsbredd. Figure 3 shows the rocker roller 1 during a combined arch maneuver. The front 2 and rear 3 bodies of the rocker roller 1 have been influenced to a pivotal movement around the vertical pivot axis of the waist joint 4 and have assumed the angled position shown in the figure. The pivotable secondary roller unit 8 has at the same time been influenced to a pivotal movement around its vertical pivot axis which cancels the effect of the pivotal movement of the bodies 2,3. The turn maneuver is called "offset control" and results in the rocker roller 1 being advanced straight ahead (or straight back). Offset control increases the working width of the cradle 1.

Vagvalten 1 i Figur 4 är helt lik vagvalten i figur 2 med ett undantag. Motorgondolen 6 är i detta andra utforingsexempel forbunden med samma kaross 2,3 som forarplattformen 5 och den sekunddra valsenheten 8 är forbundna till, d.v.s. till den framre karossen 2. Motorgondolen 6 är utformad sa att den inrymmer bade vagvaltens 1 framdrivningsmotor 9 och EAT-utrustningen 10. Midjeleden 4 är nagot forskjuten bakat fran sin ideala position mitt emellan valsarna few att ge plats at den rymligare motorgondolen 6. Vagvaltens 1 totallangd är inte langre an totallangden for vagvalten i figur 2 och dess manovrerbarhet är endast . The crank roller 1 in Figure 4 is completely similar to the crank roller in Figure 2 with one exception. In this second exemplary embodiment, the motor gondola 6 is connected to the same body 2,3 as the driver platform 5 and the secondary roller unit 8 are connected to, i.e. to the front body 2. The motor gondola 6 is designed to accommodate both the rocker 1 of the rocker roller 1 and the EAT equipment 10. The waist joint 4 is slightly offset from its ideal position between the rollers to make room for the more spacious motor gondola 6. total length is not longer than the total length of the rocker in Figure 2 and its maneuverability is only.

Som tidigare namnts, sa kan det vara problematiskt att definiera vad som är framre respektive bakre karossen pa en midjestyrd vdgvalt. Foreliggande ansokans patentkrav är darfor i sa stor utstrackning som mojligt formulerade oberoende av denna definition. Detta harmoniserar val med det faktum att uppfinningens fordelar erhalls oberoende av definitionen. 3 As mentioned earlier, it can be problematic to define what is the front and rear body of a articulated wall choice. The patent claims of the present application are therefore to the extent possible formulated independently of this definition. This harmonizes choices with the fact that the advantages of the invention are obtained regardless of the definition. 3
