Abstract

The invention relates to vehicle engineering and to other mechanisms which require the change of speed of the output shaft of an electric motor. According to the invention, the transmission ratio converter is designed in the form of a planetary differential, one central wheel of which is connected to the output shaft, the second central wheel is connected to the rotor of the electric motor, which is inductively coupled to a stator, and a carrier, on which a pair of satellite gears running on the central wheels is mounted, is connected to an additional rotor which is also inductively coupled to the stator and, when rotating, operates as a generator for producing electric energy returning it to a network and a force breaking the rotor redistributes a torque in the arms of the differential, thereby making it possible to change the speed of the output shaft.

Description

Электродвигатель с электромеханическим преобразователем передаточного отношения. Electric motor with electromechanical gear ratio converter.
Изобретение относится к области транспортного машиностроения и других механизмов, в которых необходимо изменение оборотов выходного вала электродвигателя.The invention relates to the field of transport engineering and other mechanisms in which it is necessary to change the speed of the output shaft of the electric motor.
Известны различные пути изменения оборотов ведущего вала электродвигателя переменного тока. Основным способом плавного изменения оборотов является управление частотой питающего переменного тока с использованием преобразователей частоты. Этот способ описан в литературе. Например: Вольдек А.И. Электрические машины. Ленинград. Энергия, 1978, стр. 571- 572.There are various ways of changing the revolutions of the drive shaft of the AC motor. The main way to smoothly change speed is to control the frequency of the AC supply using frequency converters. This method is described in the literature. For example: Voldek A.I. Electric cars. Leningrad. Energy, 1978, pp. 571-572.
Недостатком этого способа является большая стоимость преобразователей, их сложность, низкий КПД, ненадёжность и то, что для преобразователей электродвигателей большой мощности пока не создана надёжная элементная база.The disadvantage of this method is the high cost of the converters, their complexity, low efficiency, unreliability and the fact that for the converters of electric motors of high power a reliable elemental base has not yet been created.
Задачей изобретения является осуществление плавного изменения оборотов выходного вала устройства с изменением передаточного отношения во всем диапазоне скоростей, в зависимости от нагрузки, при оптимальном режиме работы электродвигателя на постоянных, оптимальных оборотах и, как результат, достижения оптимальности разгонных характеристик, повышения коэффициента полезного действия, удешевление производства и упрощение управления.The objective of the invention is the implementation of a smooth change in the revolutions of the output shaft of the device with a change in the gear ratio over the entire speed range, depending on the load, with the optimal operation of the electric motor at constant, optimal revolutions and, as a result, achieving optimal acceleration characteristics, increasing efficiency, and reducing the cost of production and management simplification.
Указанная цель достигается тем, что, согласно изобретению, в качестве преобразователя передаточного отношения, используют планетарный дифференциал одно из центральных колёс которого связано с выходным валом, а второе центральное колесо с ротором электродвигателя, который индуктивно связан со статором. Водило, на котором установлены пары сателлитов, обкатывающиеся по центральным колёсам, связано с дополнительным ротором, который также связан индуктивно со статором но при вращении, работает в генераторном режиме, вырабатывая электроэнергию, возвращая её в сеть, а тормозящая его при этом, сила перераспределяет крутящий момент в плечах дифференциала. Это позволяет при • постоянных, оптимальных оборотах ротора электродвигателя, изменять, в зависимости от нагрузки, обороты выходного вала.This goal is achieved by the fact that, according to the invention, as a gear ratio converter, a planetary differential is used, one of the central wheels of which is connected to the output shaft, and the second central wheel with an electric motor rotor, which is inductively coupled to the stator. The carrier, on which pairs of satellites are installed, which run around the central wheels, is connected with an additional rotor, which is also inductively connected to the stator but during rotation, operates in the generator mode, generating electricity, returning it to the network, and the power that slows it down redistributes the torque moment in the shoulders of the differential. This allows, at constant, optimal • rotor speeds of the electric motor rotor, to change, depending on the load, the speed of the output shaft.

ЗАМЕНЯЮЩИЙ ЛИСТ (ПРАВИЛО 26) Изобретение поясняется чертежом. На чертеже показан электродвигатель, с вертикальной осью вращения. Со статором 1 индуктивно связан ротор 2, который свободно вращается на оси, но жёстко связан с центральным зубчатым колесом 3 планетарного дифференциала, по которому обкатывается сателлит 4, жестко связанный с сателлитом 5, который обкатывается по центральному колесу 7, жёстко связанному с выходным валом 8. Оси сателлитов свободно вращаются на водиле 6, являющимся корпусом дополнительного ротора 9, который также индуктивно связан со статором, но работает в режиме генератора, возвращая, при вращении, выработанную им электроэнергию в цепь (подключение обмоток не показано). Возникающее при этом тормозящее усилие перераспределяет крутящий момент в плечах дифференциала, создавая условия для раскрутки выходного вала 8. Дифференциал может быть построен так, чтобы в плечо дополнительного ротора поступала значительно меньшая доля энергии, необходимая для уравновешивания второго его плеча, а вся электроэнергия, выработанная, дополнительным ротором, расходовалась на увеличение напряжённости электромагнитного поля статора. Коммутирующее устройство, определяющее величину тормозящего усилия (на схеме не показано), при необходимости может находиться в цепи обмотки дополнительного ротора, либо реализовано любым из известных способов, например изменением зазора между статором 1 и дополнительным ротором 9.SUBSTITUTE SHEET (RULE 26) The invention is illustrated in the drawing.
