Abstract
Description
460 776 Såsonx visas i Pig l lunf bakona en husvagns ll ordinarie 12, dragriktning, hjulaxel för dess hjulpar 14, 14 sett i husvagnens insatts ett extra stödhjul 6 centralt och i mitten av husvagnens bakre del 13. Stödhjulet 6 är före- trädesvis ett helgjutet gummihjul som ej behöver luftas. 460 776 Såsonx is shown in Pig l lunf bakona a caravan ll ordinary 12, towing direction, wheel axle for its wheel pairs 14, 14 seen in the caravan insert an extra support wheel 6 centrally and in the middle of the caravan's rear part 13. The support wheel 6 is preferably a fully cast rubber wheels that do not need to be vented.
Stödhjulet 6 är monterat med en fjärde axel 7 på en hj 1- hållare 10. Två hydrauliska stötdämpare 5 är insatta paral- lellt mellan hjulhàllarens 10 nedre del och en raml, lämp- ligen av en U-profil, centralt anbragt på husvagnens ll undersida bakom denna ordinarie hjulaxel 12.The support wheel 6 is mounted with a fourth shaft 7 on a hj 1 holder 10. Two hydraulic shock absorbers 5 are inserted parallel between the lower part of the wheel holder 10 and a frame, suitably of a U-profile, centrally arranged on the underside of the caravan 11 behind this regular wheel axle 12.
Hjulhállaren 10 är svängbart fäst vid ramen l med en första axel 2. Övre änden på stötdämparna 5 är svüngbart fästa vid ramen 2. Övre änden på stötdämparna 5 är svëngbart fästa vid Stötdämparnas 5 ramen l med en andra axel 3. nedre ände är svängbart fäst med en tredje axel 4 på hjulhällaren 10 något över det extra stödhjulet 6.The wheel holder 10 is pivotally attached to the frame 1 with a first shaft 2. The upper end of the shock absorbers 5 is pivotally attached to the frame 2. The upper end of the shock absorbers 5 is pivotally attached to the frame 1 of the shock absorbers 5 with a second shaft 3. the lower end is pivotally attached with a third axle 4 on the wheel holder 10 slightly above the additional support wheel 6.
Såsom framgår av Fig 3 består ramen 1, såsen: uppbär det extra stödhjulet 6, av två parallella, omvända U~profiler, vars ena ände är fäst vid en första förbindningsbalk 8 och vars andra är fäst vid en andra förbindningsbalk 9.As can be seen from Fig. 3, the frame 1, the sauce: the extra support wheel 6, consists of two parallel, inverted U-profiles, one end of which is attached to a first connecting beam 8 and the other of which is attached to a second connecting beam 9.
Vid färd med husvagnen ll dragen efter en bil trycker de hydrauliska stötdämparna 5 det ledbara extra stödhjulet 6 mot vägen och häller upp husvagnens 11 bakre del 13 från vägen. Härigenom ökar släpvagnens kultryck mot bilens dragkula jämfört med en släpvagn utan ett extra stödhjul.When driving the caravan 11 pulled by a car, the hydraulic shock absorbers 5 push the articulated extra support wheel 6 against the road and pour the rear part 13 of the caravan 11 away from the road. This increases the trailer's ball pressure against the car's towball compared to a trailer without an extra support wheel.
Detta är speciellt värdefullt vid husvagnar med hög front- profil. På husvagnar av denna typ minskar kultrycket mot bilen dragkula mycket kraftigt genom fartvinden. Sådana husvagnar blir härigenom baktunga. Detta gör att husvagnen som försvårar får pendlande rörelser, styrningen och ger sämre bromsegenskaper på dragbilen. f, .^ ~4_~_,:;«_.;;~. - i A 460 776 Det extra stödhjulets 6 maximala uppfjädring har bofunnits vara ca 20 centimeter för att husvagnen 1] skall var körbar på motsvarande sätt som en husvagn utan extra stödhjul.This is especially valuable for caravans with a high front profile. On caravans of this type, the ball pressure against the car reduces the traction ball very sharply through the wind. Such caravans thereby become rear-heavy. This means that the caravan, which makes it difficult, has oscillating movements, steering and gives poorer braking properties on the tractor. f,. ^ ~ 4_ ~ _,:; «_. ;; ~. - in A 460 776 The maximum suspension of the extra support wheel 6 has been found to be approximately 20 centimeters so that the caravan 1] can be driven in the same way as a caravan without extra support wheels.
Det har även visat sig lämpligt att anordna en gängad skruv, som påverkar stödhjulets 6 läge över marknaden, så att stödhjulet 6 vid behov kan höjas upp från markkontakt. . _ .- _, _ *är ~' 'Ü It has also proved suitable to arrange a threaded screw which affects the position of the support wheel 6 over the market, so that the support wheel 6 can be raised from ground contact if necessary. . _ .- _, _ * är ~ '' Ü
