Známe radiace a blokovacie zariadenia tohto druhu obsahujú ako radiaci člen množstvo samostatných radiacích tyčí, uložených posuvné v skrini převodovky a ovládájúcich jednotlivé radiace spojky prostředníctvom radiacích vidlic, pevne spojených s radiacimi tyčami. Poloha a vzájomné blokovanie samostatných radiacích tyčí sú zaistené pomocou blokovacích členov tvořených poistnými kolíkmi, pre ktoré sú v skrini převodovky vytvořené zvláštně vedenia. Volbu radiacej tyče pre zasunutie konkrétného převodového stupňa vykonává dalšia samostatná voliaca tyč, spojená s radiacou pákou. Zariadenia tohoto druhu sú zložené z velkého počtu dielov, sú priestorovo i výrobně náročné a výkazujú velkú hmotnost. Jednotlivé ovládacie prvky je tiež nutné pri montáži vzájomné nastavovat.Known shifting and locking devices of this kind comprise as a radiating member a plurality of separate radiating rods, displaceable in the gearbox housing and actuating the individual shifting clutches by means of radiating forks fixedly connected to the shifting rods. The positioning and interlocking of the separate radiating rods is ensured by locking members formed by locking pins for which separate guides are provided in the transmission housing. The selection of the shift rod for engaging a particular gear is made by another separate selector bar coupled to the shift lever. Devices of this kind are composed of a large number of parts, are space and production intensive and exhibit a heavy weight. The individual control elements must also be adjusted during installation.
Zo spisu GB 1 031 400 je známe zariadenie, u ktorého je nevýhoda velkého množstva radiacích tyčí odstránená použitím jediného, s radiacou pákou spojeného, radiaceho hriadela, uloženého otočné a posuvné v skrini převodovky a opatřeného kolíkmi pre záběr so samostatné uloženými vidlicami presuvných radiacích spojok. Vidlice presuvných radiacích spojok sú opatřené ramenami plochého tvaru, pomocou ktorých sú vidlice uložené otočné a posuvné na radiacom hriadeli, pričom ploché ramená radiacích vidlic výkazujú plochú část, rovnobežnú s radiacím hriadeíom a opatrenú tvarovanými otvormi s výrezmi pre záběr s vodiacimi kolíkmi.GB 1 031 400 discloses a device in which the disadvantage of a large number of radiating rods is eliminated by using a single shift lever coupled to a shifting shaft mounted rotatably and slidable in the gearbox housing and provided with pins for engaging separate shift forks. The forks of the shift clutches are provided with flat arms, by means of which the forks are mounted rotatable and movable on the shift shaft, the flat arms of the forks exhibit a flat part parallel to the shift shaft and provided with shaped holes with slots for engagement with the guide pins.
Tvar a umiestnenie výrezov na ramenách radiacích vidlic sú volené tak, aby natočením radiaceho hriadela jeden z uvedených kolíkov vstúpil do záběru s ramenom príslušnej radiacej vidlice a posuvom radiaceho hridela bola pomocou príslušnej radiacej vidlice zasunutá příslušná radiaca spojka, zatial čo kolíky pre radenie ostatných převodových stupňov sa pohybujú volné v příslušných tvarovaných otvoroch ramien radiacích vidlic.The shape and position of the slots on the fork arms are selected such that by rotating the shift shaft one of said pins engages the arm of the respective shift fork, and by shifting the shift shaft, the respective shift clutch is engaged by the respective shift fork. move freely in respective shaped holes of the fork arms.
