Abstract

The invention relates to traction and travel means, respectively, meant in particular to be used on unarranged terrains with low carrying capacity but also in other conditions. According to the invention, the traction effect and the travel effect, respectively, are carried out by the intake of air from the outer atmosphere, in the direction of travel, by a centrifugal fan () driven by an internal combustion engine (), by means of an intake hole (), rotating by 180° in the vertical plane, and discharge thereof into the atmosphere, in a direction opposite to the direction of travel, by means of one of the two discharge holes (), selected by means of a directing valve (), where the traction/travel means rests on the terrain by means of several pairs of wide drums (), free on their axles, provided with some braking washers ().

MIJLOC DE TRACTARE / DEPLASARETREATMENT / MOVEMENT MEANS

Invenția se refera la un mijloc de tractare / deplasare destinat in special utilizării pe terenuri cu portanta redusa, neamenajate, dar si in alte condiții.The invention relates to a towing / displacement means intended especially for use on low-load land, not furnished, but also in other conditions.

Sunt cunoscute mijloacele de tractare si deplasare clasice la care efectul de tractare, respectiv deplasare se realizează prin frecarea dintre rotile motoare ale acestora si terenul pe care ruleaza si care prezintă următoarele dezavantaje:The conventional means of towing and moving are known, in which the towing effect, respectively displacement, is achieved by rubbing between their motor wheels and the terrain on which they run and which have the following disadvantages:

- marimea efortului de tractare, respectiv de deplasare dezvoltat de către rotile motoare depinde de coeficientul de frecare dintre acestea si terenul pe care ruleaza, dar este influențat si de portanta terenului;- the size of the towing effort, respectively of displacement developed by the motor wheels depends on the friction coefficient between them and the terrain on which they run, but it is also influenced by the terrain load;

- pe terenurile cu portanta redusa are loc afundarea roților motoare in teren, iar pe terenuri alunecoase are loc fenomenul de patinare.- on low-load fields, the wheels of engines are sunk in the ground, and on slippery lands the phenomenon of skating occurs.

Problemele tehnice pe care le rezolva invenția sunt următoarele:The technical problems that the invention solves are the following:

- eliminarea roților motoare- removal of drive wheels

- creșterea suprafeței de contact cu terenul.- increasing the contact surface with the land.

Mijlocul de tractare / deplasare conform invenției inlatura dezavantajele menționate prin aceea ca tractarea , respectiv deplasarea se realizează prin aspirația aerului din atmosfera exterioara din sensul de deplasare de către un ventilator centrifugal acționat de un motor cu combustie interna prin intermediul unei guri de aspirație, rotitoare cu 180° in plan vertical, amplasata in partea din fata si refularea acestuia in atmosfera exterioara prin intermediul uneia dintre cele doua guri deThe towing / displacement means according to the invention removes the disadvantages mentioned by the fact that the towing or displacement is achieved by suctioning the air from the outside atmosphere in the direction of displacement by a centrifugal fan driven by an internal combustion engine through a suction mouth, rotating with 180 ° vertically, located in the front and its discharge in the outside atmosphere through one of the two mouths

Se reda in continuare un exemplu de realizare a invenției in legătură si cu fig. 1, 2 si 3 care reprezintă:An example of embodiment of the invention in connection with FIG. 1, 2 and 3 representing:

- fig.l - o vedere laterala cu rupturi;FIG. 1 is a side view with ruptures;

- fig.2 - o secțiune după planul A-A cu rupturi- fig.2 - a section according to the A-A plane with breaks

- fig.3 - o secțiune după planul B-B cu rupturi- fig.3 - a section according to the B-B plane with breaks

Mijlocul de tractare / deplasare conform invenției se compune dintr-un schelet 1 de rezistenta, pe care se reazama o carcasa 2, in interiorul careia se amenajeaza un compartiment 3 tehnic si o cabina 4 de comanda.The towing / displacement means according to the invention is composed of a skeleton 1 of resistance, on which a housing 2 is fitted, inside which a technical compartment 3 and a control cabin 4 are arranged.

In compartimentul 3 tehnic se montează un ventilator 5 centrifugal acționat de un motor 6 cu combustie interna si un rezervor 7 de combustibil.In the technical compartment 3 is mounted a centrifugal fan 5 operated by an internal combustion engine 6 and a fuel tank 7.

Deplasarea pe teren a mijlocului de tractare / deplasare se realizează prin aspirația aerului din sensul de deplasare de către ventilatorul 5 centrifugal prin intermediul unei guri 8 de aspirație, rotitoare cu 180° in plan vertical si refularea acestuia in atmosfera exterioara, in sens opus sensului de deplasare prin intermediul uneia dintre cele doua guri 9 de refulare, selectate cu ajutorul unei clapete 10 de dirijare.The movement of the towing / moving means on the ground is accomplished by suctioning the air from the direction of movement by the centrifugal fan 5 through a suction mouth 8, rotating 180 ° vertically and its discharge in the outside atmosphere, in the opposite direction of displacement by means of one of the two discharge ports 9, selected by means of a steering flap 10.

Rezemarea pe teren a mijlocului de tractare / deplasare se face prin mai multe perechi de tamburi 11 de lățime mare, liberi pe axe, prevazuti cu șaibe 12 de franare. Conducerea in plan orizontal se efectuează cu ajutorul unui volan 13 prevăzut la partea inferioara a axului cu o roata 14 dintata care angrenează simultan doua cremaliere 15 captive in scheletul 1 de rezistenta, prevăzute cu (X - 2 Ο 1 3 - Ο Ο 6 3 4The grounding of the towing / displacement means is made by several pairs of 11 wide beams, free on axles, provided with 12 brake washers. The horizontal driving is carried out by means of a steering wheel 13 provided at the bottom of the shaft with a gear 14 which simultaneously engages two captive racks 15 in the resistance skeleton 1, provided with (X - 2 Ο 1 3 - Ο Ο 6 3 4

6 -ΟΒ- 2013 urechi 16, cu canale circulare, la care se articulează capetele interioare ale axelor tamburilor 11 de lățime mare.
