具体实施方式
[0029] 下面对照附图,通过对实施例的描述,对本发明的具体实施方式作进一步详细的说明。
[°03°] 如图1至图9所示,该混合动力传动系统,包括发动机20、电动机17、发电机21、电池组19、离合器、制动器16、行星轮系以及倒挡传动轮组。
[0031] 行星轮系包括太阳轮15、行星轮14、行星轮架8以及齿圈6,太阳轮与行星轮相啮合,行星轮与齿圈的内齿相啮合,行星轮设在行星轮架上。离合器包括发动机离合器3和齿圈离合器7以及倒挡离合器5。
[OO3 2] 发动机2 O的输出轴和电动机17的输出轴并排平行设置,结构紧凑。发电机和电池组19之间、电动机与电池组之间均通过逆变器18相连。发动机与发电机之间通过齿轮组相连,齿轮组为与发动机相连的发电机主动轮I和与发电机相连的发电机从动轮2,发电机主动轮I与发电机从动轮2相啮合。
[0033] 发动机20通过发动机离合器3与齿圈6相连,齿圈6与行星轮架之间通过齿圈离合器7相连,齿圈6包括设在齿圈本体上的内圈轮齿和外圈轮齿,内圈轮齿和行星轮14相啮合,外圈轮齿和与发动机离合器相连的外齿圈驱动轮4相啮合。
[0034] 电动机与齿圈相连,电动机的输出轴上齿轮与齿圈的外齿轮相啮合。制动器16与太阳轮相连,行星轮架与车轮22相连。
[0035] 行星轮架8与车轮22相连,输出动力。具体为,行星轮架8与车轮22之间通过相啮合的行星架齿轮9和动力输出轮10相连。进一步的,行星架齿轮和动力输出轮之间可设置齿轮组或行星轮,用于速比调整等。
[0036] 倒挡传动轮组包括相连的倒挡主动轮和倒挡从动轮,倒挡主动轮通过倒挡离合器5与发动机离合器相连,倒挡从动轮与行星轮架相连。优选的,倒挡主动轮为倒挡链轮主动轮11,倒挡从动轮为倒挡链轮从动轮13,倒挡链轮主动轮与倒挡链轮从动轮之间通过链条12相连。
[0037]具有本发明混合动力传动系统的混合动力汽车,可以以多种模式运行,包括:纯电动模式、混动串联驱动模式、混动并联驱动模式、发动机单独驱动模式、行车充电模式、再生制动模式,驻车发电模式等。实现混合动力汽车在各种工作模式之间切换和运行。
[0038] 此外,根据系统和整车布置需要,电动机17和发电机21可以与齿轮结构进行一体化集成设计,也可以利用传动机构进行分布设计。因为可以利用电动机17的反转功能实现倒车,所以倒挡传动轮组可以作为选配,根据产品定义进行取舍。
[0039]如图2所示,车辆运行模式为纯电动模式,即发动机20不工作,发动机离合器3分离,切断发动机与行星轮系之间的动力传递,倒挡离合器5分离,齿圈离合器7分离,制动器16接合,仅由电动机17驱动车辆行驶。电池组19放电,经过逆变器/变压器18将直流电转换为三相交流电后驱动电动机17主轴旋转,电动机17将电能转换为机械能传递给齿圈6,同时利用制动器16锁止太阳轮,齿圈6将机械能传递给行星架8和行星架齿轮9,行星架齿轮与动力输出轴齿轮10啮合,将机械能传递给车轮22。电动机17既可以正转也可以反转,正转时车辆前行,反转时实现纯电动模式下的倒车功能。
[0040] 如图3所示,车辆运行模式为并联式混合驱动模式,即发动机20和电动机17共同工作,联合驱动车辆行驶,可以输出较大的功率,提高整车动力性。执行器状态:发动机离合器3结合,使发动机飞轮与齿轮4连接,实现能量的传递、倒挡离合器5分离、齿圈离合器7接合。发动机20输出机械能,并通过发动机离合器3传递给齿轮4,齿轮4与行星轮系的齿圈6的外齿啮合,并将机械能传递给齿圈6,齿圈6通过接合后的齿圈离合器7将机械能传递给行星架
8。同时,电动机17将电能转换为机械能传递给齿圈6,齿圈6将机械能传递给行星架8。
[0041]当车辆工作模式由纯电动切换到并联模式过程中,发动机离合器3先不接合,使用发电机21倒拖发动机20起动,然后控制发动机20调节转速,使发动机离合器3两侧的转速差较小时,再快速接合发动机离合器3,根据控制策略逐渐增加发动机扭矩,实现快速、平顺的模式切换,发动机平稳介入驱动车辆行驶,并减少发动机离合器3的滑磨,提高该离合器的使用寿命。
[0042] 此外,控制系统可以根据需求关闭或者打开发电机21的发电功能,发电功能开启后,发电机主动轮I将发动机20的部分机械能传递给发电机从动轮2,发电机从动轮2再将机械能传递给发电机21,发电机21将机械能转换为电能,可以直接提供给电动机17使用,多余的能量可以通过逆变器/变压器18将三相交流电转换成直流电存入电池组19。可以让发动机20工作在最佳燃油效率区间内,提高节油率。
[0043]如图4所示,车辆运行模式仍然为并联式混合驱动模式,与图3所示并联模式不同的地方是齿圈离合器7分离,发动机20输出的机械能通过齿圈6与行星轮14的齿轮啮合传递给行星架8;而电动机17输出的机械能通过齿圈6合传递给行星架8,行星架8混合发动机20和电动机17的机械能后,经过行星架齿轮9传递给动力输出轮10。
[0044]如图5所示,车辆运行模式为串联式混动模式,即发动机20不参与驱动车辆行驶,工作在燃油消耗率较低的工况,将动力传递给发电机21,发电机21将机械能转换为电能,产生的电能一部分提供给电动机17用来驱动车辆行驶,剩下的一部分经过逆变器/变压器18转换成直流电后存入电池组19备用。执行器状态:发动机离合器3分离,倒挡离合器5分离,齿圈离合器7接合。
[0045]如图6所示,车辆运行模式为纯发动机驱动模式及行车充电模式,即发动机20工作,而电动机17不工作,仅由发动机20提供动力驱动车辆起步和行驶。同时,还可以根据需要控制决策是否开启行车充电模式,开启行车充电模式后会将发动机20输出的机械能一部分提供给发电机21,由发电机21将机械能转换为电能存入电池组19备用。执行器状态:发动机离合器3接合,倒挡离合器5分离,齿圈离合器7接合。发动机20输出机械能,通过发动机离合器3传递给发动机齿轮4,发动机齿轮4与行星轮系的齿圈6的外齿啮合,并通过齿圈离合器7将机械能传递给行星架8,并通过行星架齿轮9将机械能传递给动力输出轮10。
[0046]当开启行车充电工作模式后,发动机20可以运行在最佳燃油效率工况区间,根据发电机21的功率需求,将发动机20输出的机械能分出一部分,并通过发电机主动轮I和发电机从动轮2传递给发电机22,发电机21将这部分机械能转换为电能,经过逆变器/变压器18将三相交流电转换为直流电后,存入电池组19备用。
[0047]如图7所示,车辆运行模式为纯发动机驱动倒车模式。在使用电能的驱动系统出现故障时,该方案不仅能够实现传统动力发动机驱动的车辆起步和行驶功能(如图6所示),还能够实现发动机驱动的倒车功能。执行器状态:发动机离合器3接合,倒挡离合器5接合,齿圈离合器7分离。发动机21输出的机械能通过发动机离合器3传递给倒挡离合器5,并通过倒挡链轮11和链条12传递给倒挡链轮13,由行星架齿轮9将机械能传递给动力输出轮10,驱动车辆实现倒车功能。
[0048] 如图8所示,车辆运行模式为滑行/制动能量回收模式,即车辆滑行或者制动时,动力系统给车辆提供反向力矩,将车辆的部分动能经由电动机17转换为电能,存入电池组19备用。执行器状态:发动机离合器3分离,倒挡离合器5分离,齿圈离合器7接合。车辆运行时因为惯性作用会具有动能,在滑行和制动工况下,电动机17开启发电工作模式,并通过变速箱的齿轮机构给车轮提供一定程度的反向力矩,减小车辆的动能,降低车速。车辆减小的一部分动能会通过车轮22转换为机械能传递给动力输出轮10,动力输出轮10通过齿轮啮合将机械能传递给行星架齿轮9,行星架8通过齿圈离合器7将机械能传递给齿圈6,齿圈6将机械能传递驱动电机17,电动机17将机械能转换为电能,经由逆变器/变压器18转换后将电能存入电池组19中备用,有利于降低油耗,提高燃油经济性。
[0049] 如图9所示,车辆工作模式为驻车充电模式。在电池组19电量较低时,可以在驻车的工况下起动发动机20,由发动机20输出机械能传递给发电机21,由发电机21将机械能转换为电能存入电池组19中。执行器状态:发动机离合器3分离,倒挡离合器5分离,齿圈离合器7不驱动处于自然状态(即离合器可以分离也可以结合)。发动机20输出机械能传递给发电机主动轮I,发电机主动轮I通过齿轮啮合将机械能传递给发电机从动轮2,发电机从动轮2将机械能传递给发电机21,发电机21将机械能转换为电能输送给逆变器/变压器18,经由逆变器/变压器18转换后将电能存入电池组19中备用。
[0050]上面结合附图对本发明进行了示例性描述,显然本发明具体实现并不受上述方式的限制,只要采用了本发明的构思和技术方案进行的各种非实质性的改进,或未经改进将本发明的构思和技术方案直接应用于其它场合的,均在本发明的保护范围之内。
