Abstract

本发明公布了一种能够降低变速器倒挡噪音的结构，其是在变速器倒挡轴上增加一橡胶减震垫。拨叉拨动惰轮在倒挡轴上移动，惰轮首先和弹性橡胶环接触，有效地避免了惰轮和倒挡轴轴肩直接接触引起的撞击声，起到减振降噪的作用。

Description

一种降低变速器倒挡噪音的结构
技术领域
本发明涉及汽车传动系统，具体涉及变速器的倒档机构。
背景技术
变速器的功能之一是通过其倒挡装置使汽车倒退行驶。挂倒挡时，驱动拨叉拨动倒挡惰轮和输入轴、输出轴上的倒挡齿轮啮合，这样动力就经过倒挡惰轮由输入轴传到输出轴，并使输出轴反向旋转驱动汽车倒退行驶。
传统的倒挡装置仅有倒挡轴和倒挡惰轮。倒挡惰轮空套在倒挡轴上。当倒挡拨叉拨动倒挡惰轮在倒挡轴上滑动时，倒挡惰轮容易和倒挡轴的轴肩产生碰撞，发出撞击声。
发明内容
本发明提供一种降低变速器倒挡噪音的结构，起到倒挡时缓冲换档冲击，从而降低噪音的目的。
为实现上述目的，本发明采用以下方案： 
一种降低变速器倒挡噪音的结构，包括倒挡轴和空套在轴上的倒挡惰轮，在倒挡轴轴肩处加装一橡胶减震垫。当挂倒挡时，拨叉拨动倒挡惰轮在倒挡轴上移动，倒挡惰轮的端面和橡胶减震垫接触，避免了倒挡惰轮和倒挡轴的轴肩直接撞击，发出噪音。
附图说明
图1为加橡胶减震垫的倒挡机构的示意图。
图中：1、倒挡轴   2、平橡胶减震垫  3倒挡惰轮   4 轴套。
具体实施方式
如图1所示，倒挡装置由倒挡轴1、平橡胶减震垫2、倒挡惰轮3、轴套4等组成。装配时，首先将平橡胶减震垫2压装在倒挡轴1的轴肩处，再将提前压装好轴套4的倒挡惰轮3空套在倒挡轴1。倒挡惰轮3能在倒挡轴1上滑动。由于增加了平橡胶减震垫2，倒挡拨叉驱动倒挡惰轮3在倒挡轴1上滑动时就不会和倒挡轴1的轴肩直接碰撞，有效地避免了噪音的产生。
