Description

电动汽车驱动桥
技术领域
本发明涉及电动汽车车桥领域，特别是涉及电动汽车驱动桥。
背景技术
在电动汽车的底盘设计方面，通常会直接借用同类燃油车的底盘设计，把电机安装在底盘上，然后通过与传动轴连接，达到驱动车辆的目的。然而这种设计有明显的弱点，即当车辆在行进中出现颠簸状态时，车桥和底盘的间距经常发生变化，使传动轴经常处于申缩变化、角度变化的状态之中，从而使机械运动的效率较低。另有的一种电机与后桥的平衡式连接，即电机固定在车桥轴上，当车桥产生颠簸时，电机也会同时产生颠簸，从而影响电机的使用寿命和效率。
发明内容
为了克服上述缺陷和不足本发明提供以下技术方案：电动汽车驱动桥，所述驱动桥包括电机、传动轴、减速器、后桥、弹簧、固定架，所述电机固定在固定架，所述电机输出轴通过联轴器A与所述传动轴一端相连，所述传动轴的另一端通过联轴器B与所述减速器的输入轴相连，所述减速器设置在后桥上，所述固定架呈“人”字形，其下部两端部连接在后桥上，其上端部设有定位连接孔，所述弹簧共两个，分别设置在固定架与后桥的连接点上，所述电机、传动轴和减速器成直线阵列。
与现有技术相比，本发明具有以下有益效果：通过将电机、车桥和传动轴连为一体，从而避免了因车辆颠簸对传动效率的影响，使传动阻力和损耗减少，提高运行效率，延长电机的使用寿命。这种结构也有利于提高安装的效率。
附图说明
图1为本发明具体实施方式的结构示意图。
具体实施方式
下面结合附图，对本发明的具体实施方式作详细说明。如图1所示，电动汽车驱动桥，所述驱动桥包括电机1、传动轴2、减速器3、后桥4、弹簧5、固定架7，所述电机1固定在固定架7，所述电机1输出轴通过联轴器A11与所述传动轴2一端相连，所述传动轴2的另一端通过联轴器B12与所述减速器3的输入轴相连，所述减速器3设置在后桥4上，所述固定架7呈“人”字形，其下部两端部连接在后桥4上，其上端部设有定位连接孔8，所述弹簧5共两个，分别设置在固定架7与后桥4的连接点上，所述电机1、传动轴2和减速器3成直线阵列，所述后桥4的两端分别连接轮胎6。
与现有技术相比，本发明具有以下有益效果：通过将电机1、车桥和传动轴2连为一体，从而避免了因车辆颠簸对传动效率的影响，使传动阻力和损耗减少，提高运行效率，延长电机1的使用寿命。这种结构也有利于提高安装的效率。
以上已对本发明进行了详细描述，但本发明并不局限于本文所描述具体实施方式。本领域技术人员理解后，在不背离本发明范围的情况下，可以作出其他更改和变形。本发明的保护范围由所附权利要求限定。
