Description

三挡电驱桥结构
技术领域
本实用新型涉及新能源汽车零部件领域,尤其涉及一种三挡电驱桥结构。
背景技术
新能源汽车越来越受到国家的重视。目前,市面上已应用的或正在研发的电驱动桥大多是单挡或两挡的结构。单挡电驱动桥可降低变速箱的复杂程度,只需配置一个减速机构就行,但对电机的需求较高,需要电机能够提供足够大的扭矩和高转速,以便适应车辆的爬坡性和高车速的要求,往往电机尺寸做的比较大,电机、电控成本较高,而且因为没有挡位的调节,电机运行在高效区间的占比不大,电机整体效率不高。两挡电驱动桥为了兼顾最高车速和最大爬坡动力性要求,要将高低挡速比之间的间比拉的很大,带来车辆换挡时不平顺,会有明显顿挫,车辆在大部分工况行驶时会出现使用低挡位车速不够,使用高挡位动力不够的情况。
因此,有必要研究一种三挡电驱桥结构来解决上述的一个或多个技术问题。
实用新型内容
为解决上述至少一个技术问题,根据本实用新型一方面,提供了一种三挡电驱桥结构,其特征在于包括:
第一传动齿轮,由电机驱动;
平行轴,固定连接有第二传动齿轮、第三传动齿轮和第四传动齿轮,第一传动齿轮与第二传动齿轮啮合;
中间轴,可相对转动地套设有第一换挡齿轮和第二换挡齿轮,第一换挡齿轮与第三传动齿轮啮合,第二换挡齿轮与第四传动齿轮啮合;
第一换挡器,可滑动地设置于中间轴且可选择地接合于第一换挡齿轮或第二换挡齿轮;
第二换挡器,设置于第二换挡齿轮或行星排的行星架且可选择地接合或断开第二换挡齿轮与行星架;
行星排,包括太阳轮、行星轮、行星架和齿圈,该太阳轮固定连接于中间轴,齿圈连接于箱体;以及
差速器,通过差速器壳体连接于行星架,且设置有第一输出半轴和第二输出半轴。
根据本实用新型又一方面,所述中间轴为中空轴,第一输出半轴穿设于该中空轴内。
根据本实用新型又一方面,平行轴与中间轴平行布置。
根据本实用新型又一方面,电机通过电机轴连接于第一传动齿轮。
根据本实用新型又一方面,电机轴与中间轴平行布置。
根据本实用新型又一方面,第一换挡被动齿轮连接有取力器或第二换挡被动齿轮连接有取力器。
根据本实用新型又一方面,所述的三挡电驱桥结构还包括设置于差速器的差速锁。
根据本实用新型又一方面,所述的三挡电驱桥结构还包括第一轮边减速行星排和第二轮边减速行星排,第一轮边减速行星排连接于第一车轮和第一输出半轴之间,第二轮边减速行星排连接于第二车轮与第二输出半轴之间。
本实用新型可以获得以下一个或多个技术效果:
1、采用双换挡器结构,实现三个挡位功能,三挡位之间的换挡间比相较两挡会大大减小,既能降低换挡冲击,提供车辆舒适性,也能提高电机的工作效率。
2、第二换挡器安装在行星排的框架或者第二换挡齿轮上,当第二换挡器的齿套与结合齿啮合时,第二换挡齿轮上的动力经第二换挡器直接传递至行星排机构的框架上,此时行星排机构不工作,减少了一级齿轮传动,提高了系统传递效率。
3、第二换挡被动齿轮左右位置各安装了一个结合齿,左位置结合齿可以与第一换挡器的接合套啮合,右位置结合齿可以与第二换挡器的接合套啮合,系统结构紧凑,轴向尺寸较小。
