232108 2 3 2 .1 (i 8 , Vynález: rieši spůsob spojenia a synchronizácíu otáčbk hriadela turbínového kolesa s hriadelom čerpadlového kolesa hydrodynamického meniča krútiac,íe.h momentov u pohonu pojazdu stroja.
Doteraz známe riešenia spojenia hriadela turbínového kolesa s hriadelom čerpadlového kolesa hydrodynamického meniča krútiacich momentov lamelovou trecou spojkou, nemajú automatické zariadenie na synchronizáciu otáčok hriadela turbínového kolesa a hriadela čerpadlového kolesa hydrodynamického meniča pri zapínaní lamelovej trecej spojky. Ovládanie trecej spojky je obvykle hydraulické a zapínanie lamelovej trecej spojky nastáva pri rozdielnych otáčkách hriadela turbínového kolesa a hriadela čerpadlového kolesa hydrodynamického meniča. Pri zapnutí lamelovej trecej spojky dochádza k okamžitému vyrovnaniu otáčok a tým k prudkej zmene rýchlosti stroja. Tento tvrdý přechod zhoršuje jazdné vlastnosti stroja, vzniknuté dynamické rázy půso-bia negativné na převodové ústrojenstvo stroja a spůsobujú zvýšené opotrebenie třecích členov lamelovej trecej spojky.
Vyššie uvedené nedostatky odstraňuje pohon pojazdu stroja, podlá vynálezu pozostávajúci z mechanickej převodovky a hydrodynamického meniča krútiacich momentov s blokováním jeho funkcie lamelovou trecou spojkou, ktorého podstata spočívá v tom, že hnacia časť lamelovej trecej spojky je otočné spojená nielen s hriadelom čerpadlového kolesa hydrodynamického meniča krútiacich momentov, ale prostredníctvom mechanického převodu aj s hnanou častou jednosmernej predstihovej spojky. Zároveň hnaná časť lamelovej trecej spojky je otočné spojená s hriadelom turbínového kolesa hydrodynamického meniča krútiacich momentov a prostredníctvom mechanického převodu aj s hnacou častou jednosmernej predstihovej spojky.
Riešením podlá vynálezu sa odstránia nežiadúce dynamické rázy v hnacom ústrojenstvo stroja pri zapínaní lamelovej trecej spojky, zvýši sa plynulost a bezpečnost jazdy. Synchronizácia otáčok hriadela turbinového kolesa a hriadela čerpadlového kolesa hydrodynamického meniča krútiacich momentov, odstráňuje pre-klzovanie třecích elementov lamelovej trecej spojky pri jej. zapínaní a pri přenose výkonu od pojazdu stroja, čím sa zníži jej tepelné namáhanie a klesnú požiadavky na jej cjimenzovanie.
Na výkresu je kinematická schéma pohonu pojazdu. stroja pozostávajúceho z mechanickej převodovky a hydrodynamického meniča krútiacich momentov s blokováním jeho funkcie lamelovou trecou spojkou. Hriadel' turbínového kolesa 1 je. s hriadelom čerpadlového kolesa 2 hydrodynamického meniča krútiacich momentov spojený lamelovou trecou spojkou 3, ktorá má vonkajšie ovládanie. Zároveň je ten istý hriadel' turbínového kolesa 1 s hriadelom čerpadlového kolesa 2 hydrodynamického meniča krútiacich momentov otočné spojený jednosměrnou předstihovou spojkou 4, ktorá prostredníctvom mechanického převodu tvořeného ozubenými kolesami 5, 6, 7, 8 tvoří zo strany hriadela turbínového kolesa 1, to znamená zo strany od pojazdu stroja s, hriadelom čerpadlového kolesa 2 hydrodynamického meniča krútiacich momentov otočné pevnú vazbu. Mechanický převod 5, 6, 7, 8 určuje převodový poměr medzi hriadelom turbínového kolesa 1 a hriadelom čerpadlového kolesa 2 a tým stupeň synchronizácie ich otáčok pri zapínaní trecej spojky 3.
Riešenie pohonu pojazdu podlá vynálezu je možné využiť vo všetkých druhoch vnzidiel a pojazdných strojov s hydrodynamickým pohonom pojazdu.
The present invention provides a method of synchronizing the speed of the turbine shaft and the pump shaft of the hydrodynamic torque converter when switching on the friction clutch to block the function of the hydrodynamic transducer by transmitting power from the machine to the drive motor by means of a direct current clutch and a permanent mechanical transmission. In this way, undesired dynamic shocks in the machine drive mechanism are removed when the locking friction clutch is engaged, driving smoothness and machine operator safety are increased.
The invention is suitable for building, forestry and agricultural machines with hydrodynamic drive.
The invention relates to a method of coupling and synchronizing a rotary shaft of a turbine wheel with a shaft of a pump wheel of a hydrodynamic converter torque, torque at a machine drive drive.
So far known solutions for connecting a turbine wheel shaft to a pump wheel shaft of a hydrodynamic torque converter with a lamella friction clutch do not have an automatic device for synchronizing the rotation speed of the turbine wheel and the shaft of the pump wheel of the hydrodynamic converter when the clutch clutch is engaged. The friction clutch control is usually hydraulic and the clutch friction clutch engagement occurs at different speeds of the turbine shaft and the pump wheel shaft of the hydrodynamic converter. When the multi-disc clutch is engaged, the speed is immediately adjusted and the machine speed is changed rapidly. This hard transition deteriorates the handling of the machine, resulting in dynamic shocks to the machine transmission and causing increased wear on the friction members of the friction clutch.
The above-mentioned drawbacks are eliminated by the machine drive according to the invention, consisting of a mechanical transmission and a hydrodynamic torque converter with a function blocking the lamella friction clutch, the principle of which is that the drive portion of the friction clutch is rotatably coupled not only to the pump wheel shaft of the hydrodynamic torque converter torque, but also by means of a mechanical transmission with the driven part of the DC direct coupling. At the same time, the driven part of the lamella friction clutch is rotatably coupled to the turbine wheel shaft of the hydrodynamic torque converter and also by means of a mechanical transmission with the driving portion of the direct-current advance clutch.
The solution according to the invention removes the undesirable dynamic shocks in the machine drive mechanism when switching on the clutch friction clutch, increases smoothness and driving safety. Synchronization of the turbine wheel shaft and the pump wheel shaft of the hydrodynamic torque converter eliminates the slipping of the frictional friction clutch elements at it. closing and transferring power from the machine, thereby reducing its thermal stress and decreasing its cushioning requirements.
The drawing shows the kinematic scheme of the drive drive. a machine consisting of a mechanical gearbox and a hydrodynamic torque converter with blocking of its function by a lamella friction clutch. The shaft of the turbine wheel 1 is. with a shaft of a pump wheel 2 of a hydrodynamic torque converter connected by a lamella friction clutch 3 having an external control. At the same time, the same shaft of the turbine wheel 1 with the shaft of the pump wheel 2 of the hydrodynamic torque converter is rotatably coupled by a one-way leading coupling 4 which, by means of a mechanical transmission formed by the gear wheels 5, 6, 7, 8, forms the shaft of the turbine wheel 1, i.e. side of the machine travel, the shaft of the pump wheel 2 of the hydrodynamic torque converter rotates the fixed coupling. The mechanical transmission 5, 6, 7, 8 determines the gear ratio between the shaft of the turbine wheel 1 and the shaft of the pump wheel 2 and thus the degree of synchronization of their speed when the friction clutch 3 is engaged.
The drive drive solution according to the invention can be used in all types of vehicles and mobile machines with a hydrodynamic drive.
