Abstract

Riešenie umožňuje montovať matice skrutiek poistených proti otáčaniu vždy z vonkajšej strany kolesa i v případe otáčania kolesa za účelom změny rozchodu. Podstatou riešenia je, že ó'patku sa opiera poistná podložka s nekruhovým středovým otvorom a čelným výstupkom zapadajúcim medzi ramená patky, pričom skrutka s nekruhovým driekom je hlavou opretá bud o poistnú podložku, alebo o disk a pod maticou skrutky je vložená podložka s kruhovým otvorom.The solution makes it possible to mount the nuts of screws secured against rotation always from the outside of the wheel even in the case of turning the wheel in order to change the gauge. The essence of the solution is that the foot is supported by a locking washer with a non-circular central hole and a front protrusion fitting between the arms of the foot, while the head of the screw with a non-circular shank rests either on the locking washer or on the disc and a washer with a circular hole is inserted under the screw nut.

Description

Vynález sa týká patkového kolesa užívaného hlavně u polnohospodárskych traktorov ako pojazdové koleso umožňujúce změnu rozchodu.BACKGROUND OF THE INVENTION The present invention relates to a bead wheel used mainly in agricultural tractors as a traveling wheel for changing the track.

Doposial známe patkové kolesá so štvorhrannou skrutkou a otvorom například zo spisu GB 2 167 717 sú riešené tak, že skrutka spájajúca patku s diskom musí mať hlavu vždy na straně disku a maticu vždy na straně opačnej k disku. Nedostatkom tohoto riešenia je, že pri otočení kolesa za účelom změny rozchodu sa dostane matica skrutky na vnútornú-neprípustnu stranu kolesa, čím sa skomplikuje údržba, pri ktorej je potřebné kontrolovat a obnovovat predpetie skrutky. Ďalším nedostatkom podobného riešenia je, že kruhová podložka opierajúoa sa o patku s prierezom tvaru U sa medzi ramenami patky deformuje a tým vzniká přídavné ohybové namáhanie skrutky.The prior art bead wheels with a square screw and a bore, for example from GB 2 167 717, are designed so that the screw connecting the bead to the disc must always have a head on the disc side and a nut always on the opposite side to the disc. A drawback of this solution is that when the wheel is rotated to change the track, the nut of the bolt gets on the inner-impermeable side of the wheel, thereby complicating maintenance where the bolt bias needs to be checked and restored. A further drawback of a similar solution is that the washer is supported on the U-shaped foot, which deforms between the legs of the foot, thereby creating additional bending stress on the screw.

Uvedené nedostatky odstraňuje patkové pojazdové koleso s patkou opierajúcou sa o disk s nekruhovými otvormi, do ktorých je vložená skrutka s nekruhovým driekom podlá vynálezu podstatou ktorého je, že o patku na straně neopierajúcej sa o disk opiera poistná podložka s nekruhovým středovým otvorom a čelným výstupkom zapadajúoim medzi ramená patky, pričom skrutka je hlavou opretá buS o poistnú podložku, alebo o disk a pod maticou skrutky je vložená podložka s kruhovým otvorom.The aforementioned drawbacks are eliminated by a bead wheel with a bead supported on a disc with non-circular bores in which a screw with a non-circular shank according to the invention is inserted, the essence of which is that the locking washer with non-circular central bore and front protrusion between the legs of the foot, the bolt being supported by the head either on the lock washer or on the disc and a washer with a circular hole is inserted under the bolt nut.

Pri otočení kolesa diskom z vonkajšej strany patky je skrutka opretá hlavou o poistnú podložku a pri otočeni kolesa diskom z vnútornej strany patky je skrutka opretá hlavou o disk. Přitom je skrutka poistená proti otáčaniu v obidvoch polohách. Matica skrutky je přístupná z vonkajšej strany kolesa vo všetkých polohách kolesa. Čelný výstupok zapadajúci medzi ramená patky jednak zaisťuje poistnú podložku proti otáčaniu, jednak vystužuje poistnú podložku v najviac namáhanom priereze, znižuje jej deformáciu a tým aj ohybové namáhanie skrutky.When the wheel is rotated by the disc from the outside of the bead, the bolt is supported by the head on the lock washer and when the wheel is rotated by the disc from the inside of the bead, the bolt is supported by the head on the disc. In this case, the screw is secured against rotation in both positions. The bolt nut is accessible from the outside of the wheel in all wheel positions. The protrusion protruding between the legs of the shoe both secures the lock washer against rotation and also reinforces the lock washer in the most stressed cross-section, reduces its deformation and thus the bending stress of the screw.

Na obrázku číslo 1 je znázorněný přiklad prevedenia patkového pojazdového kolesa podlá vynálezu, kde v dolnej polovině řezu kolesom je patkové koleso montované diskom z vonkajšej strany patky a v hornej polovině řezu je patkové koleso montované diskom z vnútornej strany patky. Na obrázku 2 je znázorněný detail z obr. 1.Figure 1 shows an exemplary embodiment of a bead wheel according to the invention, wherein in the lower half of the wheel section the bead wheel is mounted by the disc on the outside of the bead and in the upper half of the section the bead wheel is mounted by the disc on the inner side of the bead. FIG. 2 shows a detail of FIG. First

patkové koleso 11 je tvořené diskom 10 s nekruhovými otvormi 12. θ: patku 7_ na straně neopierajúcej sa o disk 10 sa opiera poistná podložka 4 s nekruhovým středovým otvorom 2 a čelným výstupkom 6 zapadajúoim medzi ramená patky 2· Skrutka 2 s nekruhovým driekom 5 je hlavou 2 opertá buS o poistnú podložku £ podlá obr. 2, alebo o disk 10.the bead wheel 11 is formed by a disc 10 with non-circular bores 12. θ : the bead 7 on the side not supporting the disc 10 is supported by a washer 4 with a non-circular central bore 2 and a front projection 6 engaging between the bead arms 2. The head 2 will either be supported on the washer 6 according to FIG. 2, or a disc 10.

Pod maticou £ skrutky 2 je vložená podložka 2 s kruhovým otvorom prekrývajúca nekruhový otvor 12 v disku 10 podlá obr. 2 alebo nekruhový středový otvor 2 v poistnej podložke 4.Underneath the nut 2 of the screw 2 is inserted a washer 2 with a circular hole overlying the non-circular hole 12 in the disc 10 according to FIG. 2 or a non-circular central hole 2 in the lock washer 4.
