Description

一种新能源汽车后置后驱动底盘
技术领域
本发明涉及一种新能源汽车底盘，具体涉及一种新能源汽车后置后驱动底盘。
背景技术
随着节能减排，低碳出行等环保意识的普及，新能源汽车发展前景越发明朗。目前，新能源汽车底盘驱动方式主要有两种：一种是前置前驱，即动力***前置前轮驱动，一种是中置后驱，即动力***中置后轮驱动。前置前驱结构的新能源汽车只适合载人，不大适合载物：载物时，货物一般放在车辆的后部，车辆后轮轴载大，前轮轴荷小，地面提供的驱动力有限，影响车辆的动力性。因此，前驱结构车辆不太适合载货车型。中置后驱结构的新能源汽车，由于传动轴布置在车辆中部，电池集中布置困难，须离散布置，间接增加了电池包成本，且前置前驱、中置后驱结构车辆前后轴载荷分布调整困难。
发明内容
针对上述现有技术存在的问题，本发明提供一种新能源汽车后置后驱动底盘，成本低廉，载人载物均可适用，能调节车辆前后轴的载荷分布。
为了实现上述目的，本发明采用的技术方案是：一种新能源汽车后置后驱动底盘，包括桥管、制动器总成、动力总成、变速箱和电池，电池与动力总成通过导线连接，还包括万向节，动力总成与变速箱通过螺栓装配在一起，动力总成与变速箱通过花键连接，桥管端头连接有制动器总成，万向节一端通过花键、螺纹与制动器总成连接，另一端通过花键与变速箱滑动连接，动力总成、变速箱位于桥管前上方，电池布置在车辆底盘中部。
进一步的，所述桥管的两侧端头分别连接一个制动器总成。
进一步的，所述变速箱通过万向节斜向与左右制动器总成连接。
本发明的有益效果是：变速箱通过万向节传递动力给制动器。为电池的布置提供了很大的空间，电池根据车辆前后轴载荷分布的情况，可以灵活调整前后位置，本发明电池集中整体安装，无需离散布置，节约了电池成本，同时避免了前轮驱动抓地力不够的缺陷，载人载物车型均适合。
