Abstract

本实用新型提出了避免互锁销脱落的装置,是在装配好的上盖总成处于挂倒档状态下,在倒档导块两侧各卡入有一个弹性卡套在倒档叉轴上,从而限制倒档叉轴的位移。变速箱上盖总成在倒档状态时加装弹性卡套限位,限制倒档叉轴位移,在互锁装置作用下将各档位叉轴锁止,使叉轴在受外力作用下不会产生轴向位移,从而防止互锁销在叉轴过档时脱落,易操作。

Description

避免互锁销脱落的装置
技术领域
本实用新型是一种避免汽车变速箱上盖总成互锁销脱落的装置。 
背景技术
汽车变速箱上盖总成在装入箱体前做功能测试及运输过程中,各档位轴在受轴向外力时位移,过档时轴中的互锁销从上盖轴孔侧壁脱出,丧失了互锁功能,在换档过程中易乱档。 
发明内容
为了防止汽车变速箱上盖总成在装入箱体前互锁销脱落,确保换档时的档位正确性,本实用新型提出避免互锁销脱落的装置。 
本实用新型的技术方案是:避免互锁销脱落的装置,其特征在于:在装配好的上盖总成处于挂倒档状态下,在倒档导块两侧各卡入有一个弹性卡套在倒档叉轴上,从而限制倒档叉轴的位移。 
有益效果:变速箱上盖总成在倒档状态时加装弹性卡套限位,限制倒档叉轴位移,在互锁装置作用下将各档位叉轴锁止, 使叉轴在受外力作用下不会产生轴向位移,从而防止互锁销在叉轴过档时脱落,易操作。 
附图说明
图1是本实用新型的剖视图。 
图2是图1中沿A-A剖视图(放大)。 
图中所示:1.上盖,2.弹性卡套,3.倒档导块,4.倒档叉轴,5.二三档叉轴,6.四五档叉轴,7.互锁销,8.互锁钢球。 
具体实施方式
如图1、2所示,在装配好的上盖1总成处于挂倒档状态下,在倒档导块3两侧各卡入有一个弹性卡套2在倒档叉轴4上,从而限制倒档叉轴的位移。倒档叉轴4在倒档位置时,互锁钢球8从倒档叉轴的槽中滚出,沿互锁孔位移至二三档叉轴5的槽中,同时使二三档叉轴5的互锁销沿二三档叉轴孔中位移,推动二三档叉轴5与四五档叉轴6之间的互锁销7进入四五档叉轴的槽中,使二三档叉轴5及四五档叉轴6均锁止,叉轴在受外力作用下不会产生轴向位移,互锁销将不会从上盖1窗口侧壁脱出。
