Abstract

一种连杆叶片液压式雨刷驱动机构，包括雨刮电机和雨刷驱动轴，其特征是：由两个叶片摆动油缸之间通过液压油管联通并传递扭矩；在主动叶片摆动油缸上设有一连杆摇臂驱动机构。本发明的有益效果是雨刮器的雨刷驱动机构用柔性管道液压传动，传递扭矩大，体积小，响应迅速，由于柔性管道液压传动，安装时受结构限制小，并且是完全的封闭结构，工作时噪声低，尤其适合外部环境结构复杂以及远距离传动，且不受外部影响，避免了因外部障碍物导致雨刮电机烧毁的弊端，有效地降低了车内噪声，提高了车辆运行时内部的舒适性。

Description

连杆叶片液压式雨刷驱动机构
所属技术领域
本发明涉及一种雨刷驱动机构，属汽车雨刮器领域，尤其是柔性管道液压传动的雨刷驱动机构。
背景技术
目前，市场上的雨刮器的雨刷驱动机构多数为连杆传动，其工作时的噪声较大，并且，连杆传动机构为敞开式，受外部影响较大，在工作时如遇到障碍物阻挡易导致雨刮电机烧毁。
发明内容
为了克服现有雨刮器驱动机构工作时噪声较大，并且，连杆传动机构为敞开式，受外部影响较大，在工作时如遇到障碍物阻挡易导致雨刮电机烧毁的弊端，本发明提供一种连杆叶片液压式雨刷驱动机构，它是一种完全封闭的结构，噪声低，传递扭矩大，响应迅速而且不受外部环境影响。
本发明解决其技术问题所采用的技术方案是：一种连杆叶片液压式雨刷驱动机构，包括雨刮电机36和雨刷驱动轴50，其特征是：雨刷驱动轴50分为被动雨刷驱动轴32和主动雨刷驱动轴49，并分别与被动叶片摆动油缸34的被动叶片摆动油缸轴51和主动叶片摆动油缸47的主动叶片摆动油缸轴52同轴相接；被动叶片摆动油缸轴51和主动叶片摆动油缸轴52上分别设有被动油缸隔板57和主动油缸隔板58，被动叶片摆动油缸34和主动叶片摆动油缸47之间通过液压油管48联通并传递扭矩；主动叶片摆动油缸47上设有一连杆摇臂驱动机构53，其结构为：在主动叶片摆动油缸轴52轴向一侧设有同轴联动的主动摇臂61，主动摇臂61通过连杆62与电机齿轮63同轴联动的电机摇臂60相连，电机齿轮63与蜗杆46相啮合，蜗杆46的一端与雨刮电机轴45相接，连杆摇臂驱动机构53设于封闭的结构内。液压油管48为柔性管。
本发明的有益效果是雨刮器的雨刷驱动机构用柔性管道液压传动，传递扭矩大，体积小，响应迅速，由于柔性管道液压传动，安装时受结构限制小，并且是完全的封闭结构，工作时噪声低，尤其适合外部环境结构复杂以及远距离传动，能够适应不同车型，且不受外部影响，避免了因外部障碍物导致雨刮电机烧毁的弊端，有效地降低了车内噪声，提高了车辆运行时内部的舒适性。
