Description

一种混联两档变速箱总成和混合动力汽车
技术领域
本发明属于汽车传动设计技术领域，特别涉及一种混联两档变速箱总成和混合动力汽车。
背景技术
混合动力汽车，一般是指油电混合动力汽车(Hybrid Electric Vehicle，HEV)，即采用传统的内燃机(柴油机或汽油机)和电动机作为动力源，也有的发动机经过改造使用其他替代燃料，例如压缩天然气、丙烷和乙醇燃料等。根据混合动力驱动的联结方式，一般把混合动力汽车分为三类：
①串联式混合动力汽车主要由发动机、发电机、驱动电机等三大动力总成用串联方式组成了该类汽车的动力系统。
②并联式混合动力汽车的发动机和驱动电机都是动力总成，两大动力总成的功率可以互相叠加输出，也可以单独输出。
③混联式混合动力汽车综合了串联式和并联式的结构而组成的电动汽车，主要由发动机、电动-发电机和驱动电机三大动力总成组成。
混合动力汽车可以有效降低燃油消耗，混合动力汽车可以结合电机、发动机特性，开发专用的少档位变速箱，固定速比的变速箱因控制简单，广受欢迎，然而目前的发动机固定速比，高效区只能兼顾中速区或者高速区，无法实现更为灵活的动力输出。
