Abstract
Description
Vynález sa týká zapojenia elektrického obvodu pre ovládáme převodového poměru · hydrostatického pohonu v závislosti od otáčok primárného vznětového motora.The invention relates to an electrical circuit for controlling the transmission ratio of a hydrostatic drive as a function of the speed of the primary diesel engine.
Doteraz sú známe dva spósoby ovládania převodového poměru hydrostatického pohonu. Jeden je mechanicko-tekutinový, u ktorého sa převodový poměr mění podl'a tlakového spádu na hydrostatickom odpore, cez ktorý preteká množstvo tekutiny priamoúmerne otáčkám primárnému vznětovému motoru. Nevýhodou tohto ovládania převodového poměru je změna tlakového spádu v závislosti od viskozity tekutiny, jej teploty a strata výkonu na hydraulickom odpore. Druhý sposob ovládania převodového poměru je založený na elektrickom principe. Signál pre převodový poměr je priamoúmerný otáčkám primárného vznětového motora. Nevýhodou tohto ovládania převodového poměru je v tom, že využívá maximálnu účinnost hydrostatického převodu iba pri maximálnych · otáčkách primárného vznětového motora.To date, two methods of controlling the transmission ratio of a hydrostatic drive are known. One is a mechanical-fluid, in which the transmission ratio varies according to the pressure drop on the hydrostatic resistor, through which a quantity of fluid flows proportionally to the speed of the primary diesel engine. The disadvantage of this gear ratio control is the change in pressure drop depending on the fluid viscosity, its temperature and the loss of power on the hydraulic resistance. The second way of controlling the transmission ratio is based on the electrical principle. The transmission ratio signal is proportional to the speed of the primary diesel engine. The disadvantage of this gear ratio control is that it utilizes the maximum efficiency of the hydrostatic transmission only at the maximum speed of the primary diesel engine.
Uvedené nevýhody odstraňuje riešenie podl'a vynálezu, ktorého podstata spočívá vo vytvoření nelineárnej závislosti signálu od otáčok, jeho časovej integrácie na signál pre vládanie převodového poměru ruhydriostatického' pohonu, ktorá je ešto riadená signálom od maximálnej dodávky paliva · na . · otáčku vstrekovacieho · čerpadla primárného · vznětového motora.The above-mentioned disadvantages are overcome by the solution according to the invention, which consists in creating a non-linear dependence of the signal on the speed, its time integration into the signal for controlling the transmission ratio of the ruhydriostatic drive. · Injection pump speed · Primary · Diesel engine.
Riešením pódia vynálezu sa dosiahne · najmenší převodový poměr pri nižších otáčkách primárného vznětového motora ako sú maximálně a tým hydrostatický převod pracuje pri maximálnej účinnosti v širšom vymedzenom otáčkovom rozsahu. Rovnoměrné zaťažovanie primárného vznětového motora sa dosiahne časovou integráciou signálu od otáčok. Riešenie podlá vynálezu zabezpečuje aj ochranu primárného vznětového motora proti preťaženiu pri změnách převodového poměru.The solution according to the invention achieves the lowest gear ratio at lower speeds of the primary diesel engine than maximum and thus the hydrostatic transmission operates at maximum efficiency over a wider limited speed range. Uniform loading of the primary diesel engine is achieved by time integration of the signal from the engine speed. The solution according to the invention also provides protection of the primary diesel engine against overload in the event of a gear ratio change.
