Description
464 398 " 10 15 20 25 30 35 vridbart lagrat i två lagerhus 5a, 5b. Staget 2 är i sina ändar fast förbundet med inbördes parallella armar 3a, 3b, som över var sin länk Ga, 6b är ledbart förbundna med var sin ände av det ofjädrade systemet 8, som innefattar lastbilens bakersta axel. 464 398 "10 15 20 25 30 35 rotatably mounted in two bearing housings 5a, 5b. The strut 2 is fixedly connected at its ends to mutually parallel arms 3a, 3b, which over each of their links Ga, 6b are hingedly connected to each end of the unsprung system 8, which includes the rear axle of the truck.
Såsom ofjädrat system betraktas i detta sammanhang differential med axlar, hjul och däck. Detta ofjädrade system är medelst ett blad- fjäderpaket fjädrande förbundet med chassiet som betraktas som det fjädrande systemet.Differential with axles, wheels and tires is considered in this context as a suspension system. This unsprung system is resiliently connected to the chassis by means of a leaf spring package which is considered to be the resilient system.
Länkarna 6a, 6b är ledbart förbundna med var sitt öra 7a, 7b, varvid vart och ett av öronen 7a, 7b är fast förbundet vid den bakre hjul- axelns ofjädrade system. Anordningen bestående av staget 2, armarna 3a, 3b, lagerhusen 5a, 5b och länkarna 6a, 6b bildar en krängnings- hämmare som påverkar såväl det fjädrade som det ofjädrade systemet med krafter, som strävar efter att hålla hjulaxeln parallell med exempel- vis det plan som definieras av rambalkarnas överkanter. Genom denna påverkan motverkas krängning.The links 6a, 6b are articulated to each ear 7a, 7b, each of the ears 7a, 7b being fixedly connected to the unsprung system of the rear wheel axle. The device consisting of the strut 2, the arms 3a, 3b, the bearing housings 5a, 5b and the links 6a, 6b forms an anti-roll bar which affects both the resilient and the unsprung system with forces which strive to keep the wheel axle parallel to, for example, the plane defined by the upper edges of the frame beams. This effect counteracts heeling.
Anordningen enligt uppfinningen innefattar utöver krängningshämmaren även en i kombination med krängningshämmaren verkande anordning för Stabilisering av lastbilen. Staget 2 är därför utrustat med ytter- ligare två inbördes parallella armar 4a, 4b. Armarna 3a, 3b är anbragta vid ändarna hos staget 2 och ligger således utanför last- bilens rambalkar. Armarna 4a, 4b är däremot så anbragta på staget 2 att de befinner sig mellan lastbilens rambalkar, varvid den vänstra armen 4a företrädesvis ligger så nära den vänstra rambalken som möjligt och den högra armen 4b ligger så nära den högra rambalken som möjligt.The device according to the invention comprises, in addition to the anti-roll bar, also a device for stabilizing the truck acting in combination with the anti-roll bar. The strut 2 is therefore equipped with two further mutually parallel arms 4a, 4b. The arms 3a, 3b are arranged at the ends of the strut 2 and thus lie outside the frame beams of the truck. The arms 4a, 4b, on the other hand, are arranged on the strut 2 so that they are located between the frame beams of the truck, the left arm 4a preferably being as close to the left frame beam as possible and the right arm 4b being as close to the right frame beam as possible.
För nämnda stabilisering och för den inledningsvis nämnda möjligheten till lasttrycksfördelning innefattar anordningen enligt den föredragna utföringsformen av uppfinningen även två hydrauliska cylindrar la, lb, som företrädesvis monteras på rambalkarnas liv och på dess insidor.For said stabilization and for the initially mentioned possibility of load pressure distribution, the device according to the preferred embodiment of the invention also comprises two hydraulic cylinders 1a, 1b, which are preferably mounted on the body of the frame beams and on its insides.
Därvid placeras cylindrarna la, lb på så sätt att cylindrarnas kolvar, när de skjuts ut bakåt, påverkar ändpartierna av armarna 4a, 4b, så 10 15 20 25 30 35 464 398 att dessa ändpartier också rör sig bakåt, varvid armarna 3a, Sb lyfts och därmed även lyfter den bakre hjulaxeln. Härvid förutsätts att armarna 3a, 3b är framåtriktade och vid normal belastning på fordonet i huvudsak horisontella. Vidare är armarna 4a, 4b så monterade på staget 2 att de, då de ej påverkas av cylindrarna la, lb vid normal belastning på fordonet, i huvudsak är lodräta eller något framåt- lutande, exempelvis 10-20°.The cylinders 1a, 1b are then placed in such a way that the pistons of the cylinders, when pushed backwards, actuate the end portions of the arms 4a, 4b, so that these end portions also move backwards, the arms 3a, Sb being lifted and thus also lifts the rear wheel axle. In this case, it is assumed that the arms 3a, 3b are forward-facing and under normal load on the vehicle are substantially horizontal. Furthermore, the arms 4a, 4b are so mounted on the strut 2 that, when not actuated by the cylinders 1a, 1b under normal load on the vehicle, they are substantially vertical or slightly inclined, for example 10-20 °.
Genom att påverka staget 2 med hjälp av hydraulcylindrarna la, lb kan man enligt denna utföringsform av uppfinningen lyfta den bakre av boggins axlar. Endera kan man arbeta med båda hydraulcylindrarna la, lb synkront och i lika hög grad, eller med endast den ena av hydraul- cylindrarna la eller lb, eller med den ena i högre grad än den andra.By actuating the strut 2 with the aid of the hydraulic cylinders 1a, 1b, according to this embodiment of the invention, the rear of the axles of the bogie can be lifted. Either one can work with both hydraulic cylinders 1a, 1b synchronously and to the same degree, or with only one of the hydraulic cylinders 1a or 1b, or with one to a greater degree than the other.
I det förstnämnda fallet lyfts den bakre av boggins axlar i lika hög grad på båda sidor. I det andra och tredje fallet lyfts endast den ena sidan av den bakre boggiaxeln. Cylindrarna la, lb kan manövreras av bilföraren exempelvis via ventiler som kan placeras i förarhytten eller på annan lämplig plats.In the former case, the rear of the bogies' shoulders is lifted equally on both sides. In the second and third case, only one side of the rear bogie axle is lifted. The cylinders 1a, 1b can be operated by the driver, for example via valves that can be placed in the cab or in another suitable place.
Alternativt kan de båda cylindrarna la, lb ersättas av en enda cylin- der, som i detta fall lämpligen placeras i chassits mitt för att påverka en uppåtstående arm i mitten av staget 2. I detta fall kan dock inte uppnås någon omfördelning av det slag som kan uppnås då man arbetar individuellt med endera av två cylindrar, såsom ovan för- klarats.Alternatively, the two cylinders 1a, 1b can be replaced by a single cylinder, which in this case is suitably placed in the middle of the chassis to actuate an upstanding arm in the middle of the strut 2. In this case, however, no redistribution of the kind can be achieved. can be achieved when working individually with either of two cylinders, as explained above.
Vid utföringsformen enligt Fig. 4 har armarna 4a, 4b försetts med en tapp 10 och cylindrarnas la, lb kolvstänger utrustats med långsträckta hål, spår, öglor eller motsvarande ll. Under körning kan tapparna l0 röra sig fritt i öglans eller motsvarande ll långhålsöppning. När respektive boggis bakre axel i samband med exempelvis tippning skall lyftas, aktiveras cylindrarna la, lb, så att kolvstången trycks bakåt, varvid boggins bakre axel lyfts.In the embodiment according to Fig. 4, the arms 4a, 4b have been provided with a pin 10 and the piston rods of the cylinders 1a, 1b are equipped with elongated holes, grooves, loops or the like 11. During driving, the pins l0 can move freely in the long hole opening of the loop or equivalent ll. When the rear axle of each bogie is to be lifted in connection with, for example, tipping, the cylinders 1a, 1b are activated, so that the piston rod is pushed backwards, whereby the rear axle of the bogie is lifted.
Samverkan mellan cylindrarna la, lb och armarna 4a, 4b kan även vara anordnad såsom visas vid utföringsformen enligt Fig. 5, varvid armarna 464 398 lO 15 20 25 30 35 4a, 4b och cylindrarnas la, lb kolvstänger är ledbart förbundna.The interaction between the cylinders 1a, 1b and the arms 4a, 4b can also be arranged as shown in the embodiment according to Fig. 5, wherein the arms 464 398 10 4a, 4b and the piston rods of the cylinders 1a, 1b are articulated.
Cylindrarna la, lb kan då sammankopplas och medelst överströmning och strypning kan en dämpningsfunktion införas.The cylinders 1a, 1b can then be connected and by means of overflow and throttling a damping function can be introduced.
