Vynález rieši spojku trecieho uzávěru diferenciálu, hlavně pře polnohospodárske traktory s tlakovým riadenim.The invention provides a clutch of the friction closure of a differential, especially for agricultural tractors with pressure control.

Známa je spojka trecieho uzávěru diferenciálu, ktorá aá skládá z vonkajšieho krytu, náboja, třecích a opěrných diskov, riadených tlakom pomocou piestu. Nedostatkom riešenia je, že náboj spojky je osadený z jednej strany vo vonkajšom kryte spojky, z druhej strany na kryte spojky. Udržanie stálej polohy náboja na kryte sa dosiahne len pomooou pružiny, umiestnenej medzi tanierové koleso a náboj, dotláčajúcou náboj do opěrného puzdra osadeného na kryte.Known is a clutch of the friction closure of a differential, which consists of an outer housing, a hub, friction and support disks, controlled by pressure by means of a piston. A drawback of the solution is that the clutch hub is mounted on one side in the outer clutch housing and on the other side on the clutch housing. Maintaining a constant position of the hub on the housing is achieved only by means of a spring located between the disk wheel and the hub, pushing the hub into the support sleeve mounted on the housing.

Uvedené nevýhody odstraňuje spojka trecieho nzáveru diferenciálu, ktorej podstata spočívá v tom, že medzi nábojom a vonkajším krytom je puzdro, ktoré je z jednej strany zasunuté do vonkajšieho krytu a na druhej straně má najmenej štyri krúžky s drážkou, do ktorej je vložený pružný krúžok. Pružný krúžok se jednou stranou opiera o vložku osadenú v otvore náboja, bodové zaistenú a druhou stranou sa opiera o čelo ná- '1 boja.These disadvantages are overcome by the differential friction clutch, which consists in that between the hub and the outer housing there is a sleeve which is inserted into the outer housing on one side and has at least four groove rings in which the elastic ring is inserted. The elastic ring is supported on one side by a liner mounted in the hub bore, fixed in place and on the other side by the front of the combat.

Výhodou vynálezu je zaistenie polohy náboja voči jej vonkajšiemu krytu a jednoduchá montáž a demontáž.The advantage of the invention is to secure the position of the hub relative to its outer casing and to easily mount and dismount.

Vynález je zobrazený na pripojenom výkrese, kde na obr. 1 je spojka trecieho uzávěru diferenciálu v pozdížnom řeze a na obr.2. je detail spojky v pohlade P podía obr. 1.The invention is illustrated in the accompanying drawing, in which Fig. 1 is a longitudinal sectional view of the friction clutch coupling and Fig. 2. is a detail of the coupling in the view P according to FIG. 1.

Spojka trecieho uzávěru diferenciálu sa skládá z vonkajšieho krytu 1, náboja 2, třecích diskov £, opěrných údskov Jj, tlakovo riadených pomocou piestu jS. Poloha náboja 2 voči jej vonkajšiemu krytu 1 je zaistená puzdrom £. Puzdro £ j® zasunuté jednou stranou do vonkajšieho krytu 1 a na druhej straně má najmenej štyri krúžky 20 a drážku £, do ktorej je vložený pružný krúžok 2.· Pružný krúžok 2. sa jednou stranou opiera o vložku 8 osadenú v otvore náboja 2, bodové zaistenú a druhou stranou sa opiera o čelo náboja 2. Vložka 8 má dutinu 15 s priemerom a šířkou umožňujúcou rozpínanie pružněr ho .krúžku 2 za účelom montáže a demontáže náboja 2, voči puzdru £. Náboj 2 má najmenej štyri otvory 21 rozmiestnené po obvode na priemere, ktorý umožňuje přístup k pružnému krúžku 2.· ^Vo vonkajšom kryte 1 je drážka £6, v ktorej sú otvory 17 a 18 privádzajúce tlakové médium do pracovného priestoru pod piestom 6_t a dva obvodové kanáliky 19 pre umiestnenie tesniacich krúžkov.'The clutch of the friction closure of the differential consists of an outer housing 1, a hub 2, the friction discs 6, the support slots 11, pressure-controlled by means of the piston 6. The position of the hub 2 relative to its outer housing 1 is secured by the housing 6. The sleeve 8 is inserted one side into the outer casing 1 and on the other side has at least four rings 20 and a groove 6 into which the elastic ring 2 is inserted. The elastic ring 2 bears on one side against the insert 8 fitted in the hub bore 2. The insert 8 has a cavity 15 with a diameter and a width allowing expansion of the elastic ring 2 for mounting and dismounting the hub 2, against the housing 6. The hub 2 has at least four openings 21 spaced circumferentially about the diameter of which allows access to the elastic second ring · ^{in the} outer housing 1 is £ groove 6 in which the openings 17 and 18 supplying pressure medium to the working space below the piston 6 _T and two circumferential channels 19 for receiving the sealing rings.
