Abstract

Riešenie sa týká predných závaží, ktoré umožňujú montáž ďalšej sady závaží, vhodné predovšetkým pre doťažovaníe polnohospodárskych traktorov. Podstatou riešenia je, že závažie je upevněné pomocou klina pridfžaného skrutkou, vloženého medzi zadnú stenu upevňovacej lišty snímatelnej konzoly a výstupky závaží. Tvar závažia umožňuje u krajných závaží sady montáž upevňovacích pátiek, na ktoré sa skrutkami a maticemi upevní ďalšia konzola shodná s konzolou a na nej ďalšia sada závaží shodných so závažiami.The solution concerns front weights, which allow the installation of another set of weights, suitable especially for additional weighting of agricultural tractors. The essence of the solution is that the weight is fixed by means of a wedge attached with a screw, inserted between the rear wall of the fixing strip of the removable console and the weight projections. The shape of the weight allows the installation of fixing feet at the extreme weights of the set, to which another console identical to the console is fixed with screws and nuts, and on it another set of weights identical to the weights.

Vynález rieši předně závažia traktora,ktoré umožňujú montáž iďalšej sady závaží,vhodné predovšetkým pre doťažovanie pol'-nohospodárskyeh strojov. Sú známe riešenia predných závaží trak-tora, u ktorých sa každé závažie upevňujeskrutkou o lištu. Nevýhodou u tohoto rie-šenia je potřeba mechanického opracovaniakaždého kusá a zdíhavá montáž i kontrolautiahnutia skrutiek celej sady závaží. U zá-važí s otvormi, cez ktoré sa tieto upevňujúskrutkami kolmo na směr jezdy stroja, sanedá změnou počtu závaží meniť doťažova-cia hmotnost. U závaží upevňovaných po-mocou západky v zadnej časti je nevýhodounutnost opatřit každé závažie nepriechod-zou dierou, vratnou pružinou a západkou,čo zvyšuje cenu závažia. U závaží upevňo-vaných priečne zasunutým čapom je nevý-hodou potřeba presnej výroby dosadacíchpléch a otvoru pre čap. Ďalšou nevýhodouznámých riešení přídavných závaží je, ženeumožňujú montáž závaží pri namontova-nom prednom trojbodovom závese.The invention firstly addresses the weight of the tractor, which allows for the installation of another set of weights, suitable in particular for the loading of semi-agricultural machines. There are known solutions for tractor front weights in which each weight is fastened to the rail by a screw. The disadvantage of this solution is the need for mechanical machining of each piece and for a quick assembly of the screws of the entire set of weights. With weights with openings through which these are fastened by screws perpendicular to the machine direction of the machine, the weight of the load is changed by changing the number of weights. For weights supported by a latch at the rear, the disadvantage of providing each weight with an impermeable hole, a return spring, and a latch increases the cost of the weight. In the case of weights fixed by a transversely inserted pin, the disadvantage is the need for precise production of the contact pads and the pin hole. Another disadvantageous solution for additional weights is that they allow the weight to be mounted when the front three-point hitch is mounted.

Uvedené nedostatky odstraňujú prednézávažia traktora, podstatou ktorých je u-pevnenie závaží pomocou klina vloženéhomedzi upevňovaciu lištu snímatelnej kon-zoly a výstupky závaží. Tvar závažia umož-ňuje u krajných závaží sady montáž upev-ňovacích patiek, na ktoré sa skrutkami u-pevní ďalšia konzola, slúžiaca k upevneniudalšej sady závaží.The aforementioned drawbacks are eliminated by the front load of the tractor, the essence of which is to fix the weight by means of a wedge inserted between the fastening strip of the removable support and the protrusions of the weight. The shape of the weight allows the mounting feet to be mounted at the outer weights of the mounting bracket, on which another bracket is provided to secure the next set of weights.

Tento sposob upevnenia závaží je nená-ročný na přesnost výroby závaží, pričomzávažie svojim tvarom umožňuje upevnitzákladnu i ďalšiu sadu použitím len jednéhotypu závažia a jedného typu upevňovacejkonzoly. Tvar závažia a upevňovacej kon-zoly umožňuje montáž závažia pri súčasnomnamontovaní predného trojbodového závěsua predného vývodového hriadeta. Tvar zá-važia ulahčuje ich nasadzovianie na lištu primontáži. Zrazenie prednej časti zmenšujeobmedzepie nájazdového uhla stroja při po-užití závažia. Zadná stená s vybráním je pri-spósobená tvaru prednej steny pre případmontáže ďalšej sady.This method of fixing the weights is not limited to the accuracy of the production of the weights, whereby the weight, by its shape, allows the base and the other set to be fixed using only one type of weight and one type of fastening bracket. The shape of the weight and the mounting bracket allows the weight to be mounted while fitting the front three-point front linkage hinge. The weight of the weight makes it easier to fit onto the mounting rail. Closing the front reduces the limit of the machine approach angle when using the weight. The recess rear wall is adapted to the shape of the front wall for mounting another set.
