Description

Vynález sa týka pohonu s dvoma elektromotormi a planétovou prevodovkou pre použitie hlavne v elektromobiloch.The invention relates to a drive with two electric motors and a planetary gearbox for use mainly in electric vehicles.

Doterajší stav technikyPrior art

V súčasnosti v každom vozidle pri rozbehu je potrebný vysoký krútiaci moment. V klasickom vozidle má prvý prevodový stupeň vysoký prevodový pomer. Na prvom prevodovom stupni sa dosahuje len malá rýchlosť a preto sa radia ďalšie prevodové stupne, ktoré zmenšujú prevodový pomer a dosahujú sa vyššie rýchlosti.At present, high starting torque is required in every vehicle. In a classic vehicle, the first gear has a high gear ratio. Only a small speed is achieved in the first gear, and therefore further gears are engaged, which reduce the gear ratio and achieve higher speeds.

Súčasné elektromobily vo väčšine používajú stály prevod od 3 : 1 do 12 : 1 v závislosti od účelu vozidla a charakteristík elektromotora, lebo elektromotor dokáže aj pri nízkych otáčkach vyvinúť vysoký krútiaci moment a tiež dosahuje vysokých otáčok na dosiahnutie vysokých rýchlostí vozidla. Nevýhodou stáleho prevodu je nízka účinnosť elektromotora v malých otáčkach, čo v mestskej premávke môže bez rekuperácie znížiť jeho dojazd až o 50 %. Vo vysokých otáčkach stráca elektromotor krútiaci moment, čo má za následok malú dynamiku.Today's electric cars mostly use a constant gear from 3: 1 to 12: 1 depending on the purpose of the vehicle and the characteristics of the electric motor, because the electric motor can develop high torque even at low speeds and also achieves high speeds to achieve high vehicle speeds. The disadvantage of a permanent transmission is the low efficiency of the electric motor at low speeds, which in urban traffic can reduce its range by up to 50% without recuperation. At high speeds, the electric motor loses torque, which results in low dynamics.

Podstata vynálezuThe essence of the invention

Uvedené nedostatky sú odstránené v predloženom vynáleze, ktorého podstata je tvorená pohonom s dvoma elektromotormi a planétovou prevodovkou, ktorý obsahuje prvý elektromotor so statorom a rotorom a druhý elektromotor so statorom a rotorom, kde stator prvého elektromotora je pevne spojený so statorom druhého elektromotora, ktoré sú spojené s rámom alebo karosériou vozidla, pričom rotor prvého elektromotora je spojený cez výstupný hriadeľ s centrálnym kolesom planétovej prevodovky a rotor druhého elektromotora je spojený s korunovým kolesom, ktoré je vybavené brzdovým kotúčom brzdy, ktorá je spojená s rámom alebo karosériou vozidla, potom korunové koleso a centrálne koleso zaberajú so satelitmi spojenými unášačom, ktorý je spojený s výstupným hriadeľom.These shortcomings are overcome by the present invention, which consists of a drive with two electric motors and a planetary gearbox, comprising a first stator and rotor electric motor and a second stator and rotor electric motor, wherein the stator of the first electric motor is fixedly connected to the stator of the second electric motor; connected to the frame or body of the vehicle, wherein the rotor of the first electric motor is connected via an output shaft to the central gear of the planetary gearbox and the rotor of the second electric motor is connected to a crown wheel equipped with a brake disc which is connected to the frame or body of the vehicle; and the center wheel engages with satellites connected by a carrier which is connected to the output shaft.

Príklady uskutočnenia vynálezuExamples of embodiments of the invention

Pohon s dvoma elektromotormi a planétovou prevodovkou obsahuje prvý elektromotor so statorom 1 a rotorom 2 a druhý elektromotor so statorom 4 a rotorom 5, kde stator 1 prvého elektromotora je pevne spojený so statorom 4 drahého elektromotora, ktoré sú spojené s rámom alebo karosériou 13 vozidla, pričom rotor 2 prvého elektromotora je spojený cez výstupný hriadeľ 3 s centrálnym kolesom 9 planétovej prevodovky a rotor 5 druhého elektromotora je spojený s korunovým kolesom 6, ktoré je vybavené brzdovým kotúčom 10 brzdy 11, ktorá je spojená s rámom alebo karosériou 13 vozidla, potom korunové koleso 6 a centrálne koleso 9 zaberajú so satelitmi 7 spojenými unášačom 8, ktorý je spojený s výstupným hriadeľom 12.The two-motor and planetary gear drive comprises a first electric motor with stator 1 and rotor 2 and a second electric motor with stator 4 and rotor 5, wherein the stator 1 of the first electric motor is fixedly connected to the stator 4 of the expensive electric motor, which are connected to the vehicle frame 13. wherein the rotor 2 of the first electric motor is connected via an output shaft 3 to the central wheel 9 of the planetary gearbox and the rotor 5 of the second electric motor is connected to a crown wheel 6 which is provided with a brake disc 10 of a brake 11 connected to the frame or body 13 of the vehicle the wheel 6 and the central wheel 9 engage with satellites 7 connected by a carrier 8 which is connected to the output shaft 12.

Pri rozbehu je aktivovaná brzda 11, ktorou je pevne zastavené korunové koleso 6 planétovej prevodovky a rotor 5 drahého motora. Takto pohon pracuje ako motor s planétovou prevodovkou s pevným korunovým kolesom 6. Prevodovka má vyšší prevodový pomer napr. 10 : 1, čo je dobré nastavenie na rozbeh a jazdu v malých rýchlostiach do 60 km/h. Pohon takto ľahko prekoná rozbehový moment vozidla a prvý elektromotor pracuje v malom rozsahu výstupných otáčok pohonu čo zvyšuje jeho eľektivitu. Pri takomto vysokom prevodovom pomere prevodovky má vozidlo pri rozbehu vysokú dynamiku aj s elektromotorom menšieho výkonu, čo zníži spotrebu energie.During start-up, the brake 11 is activated, which firmly stops the ring gear 6 of the planetary gearbox and the rotor 5 of the expensive engine. In this way, the drive works as a motor with a planetary gearbox with a fixed ring gear 6. The gearbox has a higher gear ratio, e.g. 10: 1, which is a good setting for starting and driving at low speeds up to 60 km / h. The drive thus easily overcomes the starting torque of the vehicle and the first electric motor operates in a small range of output speeds of the drive, which increases its efficiency. With such a high gear ratio, the vehicle has high starting dynamics even with a lower power electric motor, which reduces energy consumption.

V režime rozbehu sa o pevné korunové koleso 6 opierajú satelity 7 silou prenášanou z centrálneho kolesa 9. Po prekonám rozbehového momentu vozidla je sila prenášaná na korunové koleso 6 nižšia a satelity 7 rotujúce na unášači 8 unášajú korunové koleso 6 v smere otáčania unášača satelitov 8 a tým ešte znižujú silu pôsobiaci na korunové koleso 6.In the start-up mode, the satellites 7 are supported on the fixed crown wheel 6 by a force transmitted from the central wheel 9. After overcoming the starting torque of the vehicle, the force transmitted to the crown wheel 6 is lower and the satellites 7 rotating on the carrier 8 thereby further reducing the force acting on the ring gear 6.

Na dosiahnutie vyššej rýchlosti sa zmení režim pohonu tak, že prvý elektromotor je aktívny, dosiahol svoje maximálne eľektívne otáčky a rozbehol vozidlo, potom je odbrzdená brzda 11a tým aj rotor 5 motora 2To achieve a higher speed, the drive mode is changed so that the first electric motor is active, has reached its maximum effective speed and has started the vehicle, then the brake 11 is released and thus the rotor 5 of the motor 2 is released.

SK 50044-2020 A3 spojený s korunovým kolesom 6 prevodovky a je aktivovaný druhý elektromotor v smere otáčania výstupného hriadeľa 12 pohonu. Zvyšovaním otáčok rotora 5 druhého elektromotora a s ním spojeného korunového kolesa 6 prevodovky sa bude zmenšovať prevodový pomer planétovej prevodovky a tým sa budú zvyšovať otáčky výstupného hriadeľa 12. Takto elektromotory pohonu pracujú v optimálnejšom rozsahu svojej účinnosti pri nízkych aj vysokých výstupných otáčkach pohonu.SK 50044-2020 A3 connected to the crown wheel 6 of the gearbox and the second electric motor is activated in the direction of rotation of the drive output shaft 12. By increasing the speed of the rotor 5 of the second electric motor and the associated ring gear 6, the gear ratio of the planetary gearbox will decrease and thus the speed of the output shaft 12 will increase.

Ak korunové koleso 6 planétovej prevodovky je pevné, prevodový pomer prevodovky je 10 : 1. Ak má korunové koleso 6 rovnaké otáčky ako výstupný hriadeľ 12 je prevodový pomer 1 : 1. Ak má komnové koleso 6 polovičné otáčky výstupného hriadeľa 12 je prevodový pomer 5:1. Prevodový pomer 10 : 1 planétovej prevodovky nie je pevne daný a je použitý ako príklad pre lepšie vysvetlenie.If the ring gear 6 of the planetary gearbox is fixed, the gear ratio is 10: 1. If the ring gear 6 has the same speed as the output shaft 12, the gear ratio is 1: 1. If the ring gear 6 has half the speed of the output shaft 12, the gear ratio is 5: 1. The 10: 1 gear ratio of the planetary gearbox is not fixed and is used as an example for better explanation.

Rekuperácia: Pri rekuperácii vo vyšších rýchlostiach rekuperujú elektrickú energiu oba elektromotory pohonu.Recuperation: When recovering at higher speeds, both drive electric motors recover electrical energy.

V mestskej premávke je potrebné rekuperovať elektrickú energiu pri dosahovaní čo najnižších rýchlostí vozidla. Pohon v režime rozbehu má vyšší prevodový pomer ako bežné elektropohony, preto dokáže rekuperovať elektrickú energiu do nižších rýchlostí vozidla čo prináša viac elektrickej energie vrátenej späť do batérie.In city traffic, it is necessary to recover electricity while achieving the lowest possible vehicle speeds. The drive in start-up mode has a higher gear ratio than conventional electric drives, so it can recover electricity at lower vehicle speeds, which brings more electricity returned to the battery.

Rozbeh a dosiahnutie maximálnej lýchlosti je v tabuľke 1.Start-up and maximum speed are shown in Table 1.

Zmenou pomeru otáčok prvého motora a druhého motora je možné pri rovnakej lýchlosti vozidla meniť prevodový pomer planétovej prevodovky pozri tab. 2, a tým meniť aj krútiaci moment na výstupnom hriadeli 12 pohonu. Takto je možné nastaviť oba elektromotory, aby pre danú lýchlosť vozidla pracovali v optimálnych otáčkach svojej účinnosti, ako pre jazdu v ustálenej lýchlosti, tak pre maximálnu dynamiku v nízkych aj vo vyšších rýchlostiach.By changing the speed ratio of the first engine and the second engine, it is possible to change the gear ratio of the planetary gearbox at the same vehicle speed, see tab. 2, and thus also change the torque on the output shaft 12 of the drive. In this way, it is possible to set both electric motors to operate at the optimum speed of their efficiency for a given vehicle speed, both for driving at a steady speed and for maximum dynamics at both low and higher speeds.
