—种多直流轮毂电机电动车的驱动模式 - Multi-Species DC electric wheel motor vehicle drive mode

技术领域 FIELD

[0001] 本发明涉及一种多直流轮毂电机电动车的驱动模式,具体涉及一种多直流轮毂电机电动车的自动差速、无级变速驱动技术领域。 [0001] The present invention relates to a multi-wheel motor drive mode DC electric vehicle, particularly relates to a multi-speed automatic differential DC electric wheel motor vehicle, the continuously variable drive technology. 背景技术 Background technique

[0002] 随着汽车工业的飞速发展,有害尾气的大量排放和噪声严重破坏了人类的生存环境、急剧增加的能源消耗和浪费对人类未来的生存构成了严重威胁。 [0002] With the rapid development of automobile industry, a large number of harmful exhaust emissions and noise of serious damage to the human living environment, a sharp increase in energy consumption and waste for the future survival of mankind posed a serious threat. 电动车辆以其无污染、噪音小、可直接或间接利用清洁能源和再生能源的优点,受到政府、汽车生产厂家、科研院所和广大科研人员空前的重视。 Electric vehicles for its pollution, noise, can be used directly or indirectly to the advantage of clean energy and renewable energy, by the government, automobile manufacturers, research institutes and the majority of researchers unprecedented attention.

[0003]目前,电动汽车的驱动方式大多是借鉴传统汽车的驱动方式,即用电动机代替发动机作为动力源,动力(速度和扭矩)通过离合器(或液力变矩器)、变速箱,传输给差速器,然后分配给驱动轮实施驱动。 [0003] At present, the electric vehicle drive system mostly conventional reference vehicle driving mode, i.e., the electric motor instead of the engine as a power source, the power (speed and torque) by a clutch (or torque converter), gearbox, transmission to differential, and then allocated to the embodiment of the drive wheels. 这种驱动模式由于动力传递环节多,存在以下问题的:一是结构复杂、车辆自重大、总体布置困难、材料浪费严重;二是传动摩擦副多,热及振动等无功损耗大;三是由于上述两个问题,导致能源浪费大、续航能力差;四是工作可靠性较低。 This drive mode since the power transmission links, the following problems: First, complex structure, the vehicle since the major difficulties in the overall arrangement, material waste; second multi-drive friction, heat and vibration reactive power loss is large; Third due to the above two problems, leading to energy wastage, poor battery life; Fourth, lower operational reliability.

[0004] 多轮毂电机电动车,总驱动力分配于各个驱动轮上,克服了上述电动车驱动模式的不足,机械传动系统环节得到极大简化,传动效率高、耗材耗能少、工作可靠高、寿命长。 [0004] The electric vehicle multi-wheel motor, the total drive force distribution on the respective drive wheels, to overcome the deficiencies of the electric vehicle drive mode, the mechanical drive system links greatly simplified, high transmission efficiency, low energy supplies, high reliable ,long life. 在车辆总体设计时很容易采用全独立悬架设计,大大简化车辆总体布置,增加内部有效使用空间、提高车辆行驶平顺性。 When the vehicle overall design is easy all-independent suspension design, greatly simplifying the overall arrangement of the vehicle, increasing the effective use of interior space and improve vehicle ride comfort.

[0005] 由于直流电机具有优良的可调速性、过载能力强、反正转易切换、电动机-发电机可逆换,很容易满足电动车辆在无级变速、倒车、下坡或制动过程中能量回馈(增加续航能力)等车辆行驶要求。 [0005] Since the DC motor of adjustable speed excellent, strong overload, switch anyway conveyance, the motor - generator reverser, it is easy to meet the energy in the electric vehicle continuously variable, reversing, downhill or during braking feedback (increase endurance) and other vehicles travel requirements. 因此,对多直流轮毂电机电动车驱动模式的研究,具有深远的现实意义。 Therefore, the study of the current multi-wheel motor electric vehicle drive mode, with far-reaching practical significance.

[0006] 多直流轮毂电动机驱动要想较好地实际应用于电动车,必须解决:驱动轮差速、个别驱动轮打滑、电机重量大等问题。 [0006] Multi-wheel motor drive current in order to better actually used in electric vehicles, must be addressed: drive wheel speed differential, the individual wheel slip, the motor large weight problems. 具体的说就是:①各驱动轮在车辆行驶过程中差速驱动,以消除车辆在转向、行驶不平路面过程中的功率循环,导致的转向沉重(前轮驱动)、转向系和传动系过载、轮胎过度磨损、无功损耗大的问题。 Specifically, it is: ① a difference in the driving wheels during driving of the vehicle driving speed, steering the vehicle in order to eliminate, uneven road surface during driving power cycle, resulting in a heavy steering (front wheel drive), the drive train and steering system overload, excessive tire wear, no power loss big problem. ②个别车轮在冰雪路面上或泥潭中,由于轮胎附着力小,车轮打滑,整车失去驱动力。 ② individual wheels on snow or quagmire, because of the small tire adhesion, wheel slip, vehicle loss of the driving force. ③由于使用轮毂电机,驱动轮重量(非簧载质量)大,车辆行驶平顺性差。 ③ the use of in-wheel motor, the weight of the driving wheel (unsprung mass) is large, the vehicle ride comfort poor.

[0007]目前,对多直流轮毂电机驱动差速一般是采用电子控制模式。 [0007] Currently, the multi-wheel motor driving current differential is typically electronically controlled mode. 由于使用了较多的传感器、电脑和复杂的电路,价格昂贵、工作可靠性差,故障查找困难,车辆购置和使用成本高,制约了电动车的普及。 Due to the use of more sensors, computers and complex circuits, expensive, poor reliability, fault-finding difficulties, vehicle purchase and use of high-cost, restricted the popularity of electric vehicles.

[0008] 到目前,还没有一种工作可靠、结构简单、高效能的多直流轮毂电机电动车驱动模式。 [0008] Up to now, there is not a reliable, simple structure, high efficiency multi-wheel motor current electric vehicle drive mode energy.

发明内容 SUMMARY

[0009] 本发明的目的是提供一种多直流轮毂电机电动车的驱动模式,具备驱动自动差速、无级调速、解除部分电机驱动等功能,具有轮毂电机(或非簧载)质量小、工作可靠、操纵简便、成本较低的特点。 [0009] The object of the present invention is to provide a multi-wheel motor current electric vehicle drive mode, with automatic differential drive, variable speed, motor-driven lift some other functions, the motor having a hub (or sprung) small mass , reliable, easy manipulation, low cost.

[0010] 本发明采用以下技术方案:电动车驱动系统主要由若干个相同规格的直流轮毂电机Mi、短路开关1、升压器、PWM脉宽调制调速器和电池组构成。 [0010] The present invention employs the following technical solution: an electric vehicle drive system is mainly Mi, the short-circuit switch 1, the booster, the PWM pulse width modulator governor and the battery pack consists of a plurality of the same specification DC wheel motors. 其中:升压器结构为“直-交-升压-直”型,由逆变器、升压变压器和整流器构成;电机及其对应短路开关的数量根据车辆设计需要确定。 Wherein: structure booster "DC - AC - Boost - straight" type, constituted by an inverter, step-up transformer and rectifiers; motor and a corresponding number of short-circuiting switch is determined according to the vehicle design.

[0011] 联接方式和部件的目标功能:①直流轮毂电机Mi (绕组)依次串联,实现电机差速驱动。 [0011] The target function and mode coupling means: ① the DC wheel motors Mi (winding) in series, to achieve the differential drive motor. ②短路开关Ki分别与电机Mi—一对应并联。 ② shorting switch Ki respectively corresponding to a motor Mi- parallel. 当个别驱动轮打滑时,闭合其短路开关将轮毂电机短路而临时解除驱动,其他轮毂电机获得更大的能量。 When individual wheel slip, which is closed shorting switch wheel motor drive shorted temporarily release, the other wheel motor greater energy. ③升压器提升电池组电压,减小电机重量。 ③ lift booster battery voltage, reducing the weight of the motor. ④PWM脉宽调制调速器直接控制和改变电池组能量输出给升压器,实现无级变速。 ④PWM directly control the pulse width modulator and governor to change the battery pack to the power output of the booster, to achieve a continuously variable transmission.

[0012] 与常见的电子控制电机驱动差速模式相比,本模式有以下优点:①不需要差速控制电路,就能实现驱动过程中驱动轮自动差速。 [0012] Compared with a common motor-driven electronically controlled differential mode, the present mode has the following advantages: ① not require differential control circuit can be realized automatically during the driving wheels differential. ②传感器、控制和执行电路、电脑等电子元器件使用少,PWM脉宽调制调速、逆变、变压和整流等技术成熟,且PWM脉宽调制调速器布置在低压端。 ② sensors, control and execution circuit, the use of small computers and other electronic components, pulse width modulation PWM control, the inverter, and a rectifier transformer technology is mature, and the PWM pulse width modulation speed is arranged at the low pressure side. 故而,结构简单、工作可靠、成本低。 Therefore, the structure is simple, reliable and low cost. ③个别车轮打滑车辆失去驱动力时,很容易切换掉打滑的驱动轮(在驱动主电路中用开关短路电机绕组,使之不工作),使整车辆恢复或获得驱动力。 ③ When the individual loses a driving force of the vehicle wheel slip, it is easy to switch off the drive wheel slip (by driving the main circuit switching shorting the motor windings, so as not to work), so that the entire vehicle recovery or obtaining a driving force. ④适用范围宽,设计简单,可用于两轮及以上驱动轮的电动车辆。 ④ wide scope, a simple design, and can be used for two or more wheels of the electric vehicle.

[0013] 下面结合附图和实施例对本发明作进一步详细的说明。 Drawings and embodiments of the present invention will be further described in detail [0013] below in conjunction.

[0025](注:以上电流强度I和反电动势ε皆为瞬态值。) [0025] (Note: the counter electromotive force current intensity I and ε are all transients.)

具体实施例 Specific Example

[0026] 依照附图中等效电路,对直流电机进行瞬态分析: [0026] In accordance with the drawings in an equivalent circuit of the DC motor transient analysis:

[0027] I、自动差速 [0027] I, automatic differential

[0028] 由物理学知识知,对于串联的直流电动机绕组,有: [0028] known from the knowledge of physics, for the DC motor windings in series, are:

[0029] I = (V- Σ ε ^/(R0+nR).................................... (I)[0030] Eei= ε j+ ε 2+··· + ε η .................................... (2) [0029] I = (V- Σ ε ^ / (R0 + nR) ................................. ... (I) [0030] Eei = ε j + ε 2 + ··· + ε η ............................ ........ (2)

[0031] 从式中出发进行分析推断:由于直流电机的结构参数皆相同,当我们将它们串联起来并在两端施加电压时,在任意时刻,不论电机转速如何不同(车辆转向或在不平路面上行驶),每个电机绕组通过的总电流都相同。 [0031] From the estimation formula for analysis: the structure parameter of the DC motor are the same, when we are in series and applying a voltage across, at any time, regardless of how different motor speed (or rough road vehicle steering traveling), the total current through the motor windings each are the same. 进一步说,就是在上述情况中,不管直流电机的结构形式为并励、串励、复励直流电机,还是永磁直流电机,每个直流电机的转子和定子绕组中的电流都分别相同(永磁直流电机只有定子或者转子)。 Further, in the above case it is that, regardless of the structure of a DC motor and shunt, series-wound, compound excitation DC motor, or a permanent magnet motor, the rotor current and stator windings in each of the DC motor are respectively identical (Yong DC magnetic rotor or the stator only). 那么,此时每个直流电机的转矩(驱动力)都相同。 Then, when each of the DC motor torque (driving force) are the same. 这是实现自动差速的理论基础。 This is the theoretical basis of automatic differential.

[0032] 我们用实际运行试验,对上述结论进行了正确性和可行性验证。 [0032] we use the actual running test on the above conclusions were correct and feasible verification.

[0033] 2、解除个别打滑驱动轮的能量输入,恢复或获得整车驱动力 [0033] 2, releasing individual energy input drive wheels slip, the driving force of the vehicle is obtained or recovery

[0034] 当个别驱动轮行驶在冰雪路面或泥潭中时,车轮转速会迅速增加而打滑,整车失 [0034] When the individual driving wheels in a snowy road or puddle, the wheel speed will rapidly increase and slippage, loss of vehicle

去驱动。 To drive. 其原因是:这些(或个)轮毂电机通过轮胎施加给地面的抓地力大于地面的附着力,轮胎打滑,电机转速迅速上升,所述电机的反电动势ε同时迅速上升,由(I)式可知Σ ε i迅速增大,导致I迅速减小,各驱动轮输出扭矩也迅速减小。 The reason is: these (or more) applied to the motor hub by the tire adhesion to the ground surface is larger than the grip, tire slip, the motor speed rises rapidly, the motor counter electromotive force ε rises rapidly while, seen from formula (I) Σ ε i is rapidly increased, leading to rapid decrease I, each of the output torque of the drive wheels decreases quickly. 当直至V = Σ ε i时,电池组输出的能量几乎全部供给滑转的驱动轮,整车失去驱动力。 When until V = Σ ε i, the energy of the battery output supplied to almost all the wheels slip, the vehicle driving force is lost.

[0035] 在上述情况下,若闭合滑转驱动轮(轮毂电机)对应的短路开关将电机绕组短路,就可使这些(或个)轮毂电机排除在整个驱动系统之外,而驱动主电路仍然连通,电池组输出的能量供给其余的轮毂电机(驱动轮),使车辆恢复或获得驱动力前行。 [0035] In the above case, if the drive wheels slip closed (wheel motor) corresponding to the short-circuiting switch the motor winding short circuit, it is possible to make these (or more) wheel drive motor excluded from the entire system, and drives the main circuit is still communication, energy battery output supplied to the rest of the wheel motor (driving wheels), or to restore the vehicle obtained before the driving force line. 这类似一般汽车的“差速锁”。 This is similar to the general car "differential lock."

[0036] 3、无级变速 [0036] 3, a continuously variable transmission

[0037] 由非常成熟的PMW脉宽调制调速器的PWM脉宽调制电路技术,控制和改变电池组平均电流强度(功率或能量)的输出,从而控制和改变各直流轮毂电机的输出速度和扭矩,实现电动车无级变速。 [0037] The pulse width modulation by the PWM circuit technology is very mature governor PMW pulse width modulator controls the output of the battery pack and change the average current intensity (power or energy) so as to control and change the output speed of each wheel motor and DC torque electric cars to achieve a continuously variable transmission. 由于PWM脉宽调制调速器直接控制低压输出,提高了工作可靠性、降低了成本。 Since the PWM pulse width modulation speed control direct voltage output, improve reliability and reduce costs.

[0038] 4、升高驱动直流电机驱动电压,减小电机重量,提高车辆行驶平顺性 [0038] 4, elevated driving voltage DC motor drive, the weight of the motor is reduced, improving ride comfort of the vehicle

[0039] 结合对自动差速的分析,对(I)式进行进一步分析: [0039] Analysis of the binding of the automatic differential of formula (I) for further analysis:

[0040] 若仍采用低电压驱动,采用电机串联驱动,(RQ+nR)势必增大,势必引起电流I减小,导致每个直流电机出力减小。 [0040] If the still low voltage driving, using the driving motor in series, (RQ + nR) bound to increase, is bound to cause the current I decreases, resulting in each of the DC output decreases. 为达到车辆的驱动要求,必须增大电流I,即只能减小(Ro+nR)。 To achieve the required vehicle drive, it is necessary to increase the current I, which can only be reduced (Ro + nR). 由于Rtl由车辆结构参数确定,只能减小R,即增加绕组线径。 Since Rtl determined by the structural parameters of the vehicle, only reduce R, i.e. to increase the winding diameter. 这样带来的不仅仅是由于电机重量的增加、车辆行驶平顺性下降的问题,而且还带来由于Rtl分压增加导致无功热损耗增加、车辆续航能力下降的问题。 Such brings not only due to the increased weight of the motor vehicle ride comfort drop problem, but also cause problems due to the increasing partial pressure leads to an increase Rtl reactive heat losses, decrease the battery life of the vehicle.

[0041] 采用“直-交-升压-直”升压器放大电池组的输出电压,以提高每个直流轮毂电机的驱动电压,有效地解决了上述问题。 [0041] The "DC - AC - Boost - straight" booster amplifies the output voltage of the battery, to increase the DC voltage of each driving wheel motor, to effectively solve the above problems. 同时,还能通过电机优化选型,最大限度地减小电机绕组线径,减小电机重量,提高车辆行驶平顺性。 Meanwhile, also optimize the selection by a motor, the motor winding diameter minimizing, reducing the weight of the motor vehicle to improve ride comfort.

[0042] 综上所述,该“多直流轮毂电机电动车的驱动模式”,能完全满足电动车驱动、操纵和乘坐要求。 [0042] In summary, the "plurality of DC electric wheel motor vehicle drive mode", can fully meet the electric vehicle driving, steering and ride requirements. 采用本技术方案的电动车不但具备差速、差速锁、无级变等功能,而且工作可靠性和行驶平顺性高、制造和使用成本低、操纵简便,对电动车的普及具有非常积极的促进作用。 According to this aspect of the electric vehicle includes not only a differential, differential lock, stepless variable functions, reliability and low and high ride comfort, and the manufacturing cost, easy to manipulate, the popularity of electric cars have a very positive enhancement.
