Description
Predmetom vynálezu je zdrojová jednotka pre napájanie elektrického zapalovania raotorov špeciálnych vozidiel najma pojazdných hasiacich zariadení.The subject of the invention is a power supply unit for supplying electric ignition of special vehicle rotors, in particular mobile fire extinguishers.
Pre štartovanie raotorov, ktoré neraajú běžný motorový startér v spojení s batériou sa používajú rozné zariadenia pre štartovanie motora, a to najraá u špeciálnych účelových vozidiel. Tieto štartovacie zariadenia sú vačšinou raagneto-elektrické a pracujú na principe magnetickej indukcie v cievkach, v ktorých sa indukuje elektrické' napatie pohybom permanentných raagnetov okolo cievok. Tieto zariadenia sú poměrně zložité a výrobně náročné a obsahujú vela mechanických častí, ktoré musia byť velmi presne vyrobené na náročnom výrobnom zariadení. Vzhladom na ich vysoké přesnost a na podmienky prevádzky dochádza k ich poruchám a vyradeniu.A variety of engine starting devices are used to start rotors that do not mow a conventional motor starter in conjunction with a battery, and this is especially true for special purpose vehicles. These starter devices are mostly raagneto-electric and operate on the principle of magnetic induction in coils in which electrical voltage is induced by moving the permanent magnets around the coils. These devices are relatively complex and labor intensive and contain a lot of mechanical parts that must be manufactured very precisely on a demanding manufacturing facility. Due to their high accuracy and operating conditions, they are malfunctioning and discarded.
Tieto nedostatky odstraňuje zariadenie podlá vynálezu. Zdrojová jednotka podlá vynálezu má nahradené přesné mechanické časti elektronickými, ktoré sú v podstatě výrobně jednoduchšie ako aj mertej náročné na údržbu a prevádzku. Zdrojová jednotka podlá vynálezu obsahuje alternátor, ktorý je upevněný na otočnom čapě v púzdre zdrojovej jednotky, ktoré je připevněné přírubou na blok motora. Pri startovaní motora sa ručně roztáča veniec zotrvačníka, -ktorý je v zabere s kolieskom alternátora. Koliesko roztáča alternátor a tým sa vytvára energia v alternátore pre elektrické zapalovanie motora. Keď sa motor nastartuje, nastane v nasávacom potrubí podtlak, ktorý je vedený trubičkou do podtlakového ovládača, ktorý uvedie do pohybu západku a páku a nastane vyklonenie alternátoru a tým sa jeho koliesko odklopí zo zaberu.These drawbacks are overcome by the device according to the invention. The power supply unit according to the invention has been replaced with precision mechanical parts by electronic ones, which are substantially simpler to manufacture as well as being very demanding in terms of maintenance and operation. The source unit according to the invention comprises an alternator which is mounted on a pivot pin in the housing of the source unit, which is fixed by a flange to the engine block. When starting the engine, the flywheel rim, which engages the alternator wheel, manually turns. The wheel turns the alternator and thus generates energy in the alternator for electric ignition of the engine. When the engine starts, there is a vacuum in the intake manifold, which is guided through the tube to the vacuum actuator, which moves the latch and lever, and the alternator tilts, thereby swiveling the wheel off the engagement.
Na priloženom výkrese je znázorněný příklad vyhotovenia zdrojovej jednotky podlá vynálezu, kde na obr. 1 je priečný osový rez jednotkou a na obr. 2 je čelný pohlad na zdrojové jednotku podlavynálezu.In the accompanying drawing, an example of an embodiment of a source unit according to the invention is shown. 1 is a cross-sectional axial section of the unit; and FIG. 2 is a front view of the source unit of the invention.
V púzdre j_, ktoré má prírubu 7. je otočné uložený alternátor 2., ktorý má na jednom konci koliesko 3. Alternátor 2 je spojený druhým koncom pákou 8, so západkou 4., ktorá má výřez a je zasunutá do podtlakového ovládača 5, spojeného trubičkou 6. s nasávacím potrubím, V púzdre zdrojovej. jednotky je zabudovaná príechodkaAn alternator 2 having a wheel 3 at one end is rotatably mounted in a housing 7 having a flange 7. The alternator 2 is connected to the other end by a lever 8, with a pawl 4 which has a cut-out and is inserted into a vacuum actuator 5 connected tube 6 with suction pipe, in the source housing. unit is built in
Pri Startovaní motoru sa ručně roztočí zotrvačník motora, na ktorom je veniec čo zaberá do kolieska 3_ alternátoru 2_ a ten sa roztočí a vytvára energiu v alternátore 2. pre elektrické zapalovanie motora, Keď nastane zapálenie motora, nastane v nasávacom potrubí podtlak, ktorý sa trubičkou _6 prenesie do podtlakového ovládača 5. a zasunie sa západka £, ktorá je spojená s pákou 8, a ta otočí alternátor _2 a tým vysunie koliesko 3. zo záběru. Zdrojová jednotka je tak v klude. Zdrojová jednotka podlá vynálezu je vhodná pre Speciálně vozidla s motorom najmá pre protipožiarné zariadenia.When starting the engine, the flywheel of the engine is rotated by hand, on which a rim engages into the wheel 3 of the alternator 2 and it spins and generates energy in the alternator 2 for electric ignition of the engine. 6 is transferred to the vacuum actuator 5 and the latch 8, which is connected to the lever 8, is engaged, and it rotates the alternator 2 and thereby disengages the wheel 3 from the engagement. The source unit is thus quiet. The power supply unit according to the invention is suitable for special vehicles with an engine especially for fire-fighting equipment.
