Description
技术领域
本发明属于车辆传动技术领域,具体涉及一种混合动力多挡变速箱。
背景技术
混合动力技术具有降排放和油耗的优点,同时提高车辆动力性能,成为未来汽车动力传动技术的发展方向。并联形式的混合动力优点在于:发动机的动力可以直接用来驱动车辆,没有能量转换,能量损失小,结构简单;电机既可作为电动机使用,也可作为发电机使用,且可以采用较小功率的电机,结构简单,成本低。并联形式混合动力技术中电机主要实现急加速工况或者发动机低速工况下的助力,提高动力性能,改善发动机的燃油经济性;在减速工况,实现制动能量回收;在低速以及起步工况,可实现纯电驱动工况。相比于串联形式混合动力技术适合于低速,经常启停工况的城市车辆,并联形式混合动力技术更适合于中高速、需求动力性能的商用车、越野车以及特种车辆。
根据电机的位置不同,并联式混合动力分为三种:第一种是电机布置在变速箱的离合器前面,其特点是电机可利用变速箱的传动比调节传动范围,电机自身转速、转矩性能需求低,电机体积重量小,但换挡过程中有动力中断,需要同步的惯量较大;第二种是电机布置在变速箱输出轴后面,其特点是换挡过程中无动力中断,但电机的转速、转矩性能要求高;第三种是电机布置在变速箱中间轴上,其特点是采用多自由度齿轮机构耦合电机和发动机的动力,实现混合动力和动力换挡功能。
传统的手动变速箱在换挡过程存在动力中断,影响汽车的动力性。中国专利200910215341.X中的变速器通过机械机构实现动力换挡设计,但其换挡过程中,需要机械机构相互之间的配合,并难以实现混合动力功能。采用上述描述的第三种电机布置形式的动力换挡并联形式的混合动力技术方案,可以实现动力换挡,提高动力性能以及换挡舒适性,并且可利用多自由度定轴齿轮机构实现多个匹配发动机挡位以及多个匹配电机挡位。
发明内容

况,提升车辆动力性能,改善换挡品质,降低离合器磨损,提高燃油经济性。

发动机的动力通过离合器输入到发动机输入轴;电机的动力输入到电机输入轴;变速箱耦合发动机与电机的动力。
有益效果:(1)本发明中发动机、离合器、电机、变速箱同轴布置,适合于传统车辆动力***,便于空间布置;多自由度定轴齿轮变速机构由6对齿轮机构,3.5个同步器组成,通过齿轮对的重复利用,可以提供7个匹配发动机的挡位,3个匹配电机的挡位。
(2)本发明匹配发动机的挡位与匹配电机的挡位不同时换挡,匹配发动机的挡位换挡时,匹配电机的挡位提供转矩支持,反之亦然;通过换挡过程中的转矩支持,实现了动力换挡,提高动力性能和换挡舒适性。
(3)本发明采用电机挡位起步,降低了离合器起步的控制难度以及离合器的磨损,提高了起步舒适性可车辆低速可控性;电动机与多自由度定轴齿轮变速机构提供电动倒挡功能,取消了倒挡齿轮对,提高了齿轮机构的紧凑度。
(4)本发明可实现并联形式的混合动力技术,在低速工况可实现纯电驱动,急加速工况实现混合驱动,减速工况实现制动能量回收。
(5)由于本发明存在多个匹配电机的挡位,电机所需的功率及转矩较小,有利于提高传动***的功率密度;本发明功率传递路径简单,大多数档位下动力只经过两次齿轮啮合输出,功率损失小,变速机构效率高。
(6)本发明匹配发动机的挡位换挡时,同步器所需的同步惯量小,有利于缩短换挡时间,降低了同步器的负荷,提高同步器的寿命;电动机换挡时,可利用电机的转速调节功能同步齿轮转速,改善换挡性能。
