Abstract

The controller has a handle, which is fixed to the pivot, which is hinged in the upper fork. The spring leaning against the washer, secured by the lock, is placed on the pivot inside the upper fork. There is an oblong recess for movement of the handle on the lateral side of the front fork. The controller removes the possibility of appearance of collision with other elements of the tractor during regulation of trailer length.<IMAGE>

Description

Vynález rieši ovládáš ručnej regulácia závesnej súpravy náradia traktore, slúžiaci na změnu dížky závesov z vonkajšej strany traktora·The invention solves you control the manual regulation of the tractor tool suspension set used to change the length of the suspension from the outside of the tractor.

Podía patentu PCR č. 135 834 Je známe klukové ústrojenstvo na ručnú reguláciu závesnej súpravy náradia traktora vybavené doplňkovou klukou ualsstnsnou na vonkajšej straně kabiny traktora. Kluka je otočné upevněné v hornej vidlici uloženej na mnohouholnikovej tyči. Kluka sa skládá z vyhnutsj tyče, ktorej kratší koniec Je vsunutý do otvoru hornej vidlice a dlhši koniec tvoři rukovfft a mé na jednej strano vidlice pružinu oplerajúcu aa o podložku zaletenú závlačkou a na druhej etranš vidlice mé převlečený kolik,’ ktorý zapadá do vybrania na čelnej ploché hornej vidlice. Toto klukové ústrojenstvo nezabezpečuje odstránenie možnosti vzniku kollzie e inými elementární počaa regulácia dížky závěsu.According to PCR patent no. 135 834 There is known a crank mechanism for manually adjusting a tractor toolkit equipped with an additional handle ualsstnsnou on the outside of the tractor cab. The jack is rotatably mounted in the upper fork mounted on a polygonal rod. The crank consists of an elongated rod whose shorter end is inserted into the opening of the upper fork and the longer end is formed by a handle and my one side of the fork is spring-lined and cottered with a cotter pin. flat top fork. This loop device does not ensure the elimination of the possibility of collision by other elements during the regulation of the hinge length.

Uvedené nedostatky odstraňuje vynález, ktorého podstata spočívá v tom, že ovládač má rukovfft upevnenú pevne ne čapě umiestnenom otočné v hornej vidlici. Na čapě vo vnútri hornej vidlice Je umiestnená pružina opierajúca ea o podložku zabezpečená závlačkou. Na bočnom povrchu hornej vidlice Je pozdížna priehlblna.The above-mentioned drawbacks are overcome by the invention, which is characterized in that the actuator has a handle fastened firmly to a pivot arranged rotatably in the upper fork. On the pivot inside the upper fork, there is a spring resting on ea on the washer secured by a split pin. There is a longitudinal depression on the side surface of the upper fork.

Ovládač podía vynálezu odstraňuje možnost vzniku kolízie e inými elementární traktora počas regulécie dížky zévesu.The actuator according to the invention eliminates the possibility of collision with other elementary tractors during the regulation of the length of the hitch.

Vynález je znázorněný na přiložených výkresoch, kde na obr. 1 Je klukové zariadenie e ovlédačom na zadnom kolese traktora v schematickom znázorněni a na obr. 2 je ovládač v neutrálnej polohe.The invention is illustrated in the accompanying drawings, in which: FIG. FIG. 2 the actuator is in the neutral position.

Ovládač sa skládá z rukovfftl l.» čapu 2, hornej vidlice J3, mnohouholnikovej tyče 4,, pružiny 5/ podložky 6 a zévlačky 7. Rukovfft .1 je upevněné pevne na čapa 2 umieatnenom otočné v hornej vidlici 3 a Je spojené e mnohouholnikovou týčou 4. Na čapě 2 vnútri hornej vidlice 3 je osadené pružina ji opierajúca ea o podložku £i zabezpečená závlačkou 7.The actuator consists of a handle 11, a pin 2, an upper fork 13, a polygonal rod 4, a spring 5 / washer 6, and a sleeve 7. The handle 11 is fixed firmly to a pin 2 positioned rotatably in the upper fork 3 and connected by a polygonal rod. 4. On a pin 2 inside the upper fork 3, a spring is supported on it by means of a cotter 7.

Na bočnom povrchu hornej vidlice 3 Je pozdížna priehlblna 8. Ovládač mé dva polohy: neutrálnu a pracovnú.On the side surface of the upper fork 3 There is a longitudinal recess 8. The actuator has two positions: neutral and working.

V neutrálnej polohe rukovfft 1. ovládača vchádza do priehlblny JS v hornej vidlici 3 a má polohu rovnobežnú a mnohouholnikovou týčou 4. Po přitlačeni rukovfftl JL malou ailou nastane otočenle čapu 2 v hornej vidlici 3. Ak rukovfft JL zaujme v přibližovaní polohu kolmú k osi, ovládač Je možné otáčet okolo osi mnohouholnikovej tyče 4/ skracujúc alebo predlžujúc závěs 9 závesnej eúpravy náradia traktora*In the neutral position of the handle 1 of the actuator, it enters the recess JS in the upper fork 3 and has a parallel and polygonal position 4. When the handle 2 is pressed by the small ail, the pivot 2 in the upper fork 3 is rotated. control It is possible to rotate about the axis of the polygon bar 4 / shortening or extending the hitch 9 of the suspension of the tractor tool *

Claims

Hand control for suspension adjustment of tractor implements and a handlebar mounted in a fork mounted rigidly with a polygonal rod of the kiuk device and also with a latch (characterized in that the handlebar (1) is fixed firmly on a pivot (2) in which a spring (5), supported on the washer (6), is secured within the upper fork (3) by a cotter pin (7), with a longitudinal depression (8) on the side surface of the upper fork (3).
