Non destructive anti-theft steering column assembly. The utility model mainly solves the problem that the existing steering tube column assembly is easy to cause the ignition switch and the associated component to be damaged. The utility model is characterized in that the spline shaft (2) is provided with an opening elastic sleeve (5), and an outer sleeve of the elastic sleeve (5) is provided with a spline shaft sleeve (6). The non destructive anti-theft steering column assembly with torque protection function, when the spline sleeve to withstand the torque is too large, can slide between the spline sleeve and the spline shaft, the torque is too large and the ignition switch and the associated components are damaged, has the advantages of simple structure, convenient installation, convenient adjustment, switch the location is accurate and reliable safety steering.
【技术实现步骤摘要】
本技术涉及一种汽车转向操纵机构,尤其是非破坏性防盗转向管柱总成。
技术介绍
目前,汽车转向操纵机构主要由方向盘、转向轴总成及转向管柱总成组成,其作用是将驾驶员转动方向盘的操纵力矩传给转向器。其中的转向管柱总成主要由套管及花键轴组成,套管通过轴承安装于套管内,花键轴上焊接有外壁带键槽的花键轴套,套管安装于托架上,套管外安装有点火开关,点火开关内设有与花键轴套上的键槽相对应的锁舌,当点火钥匙关闭时,锁舌可以进入花键轴套上的键槽,卡住花键轴使其不能转动,使汽车方向锁住,起防盗作用;当点火钥匙打开时,转动花键轴锁舌会自动縮回,花键轴可自由转动。现有的转向管柱存在以下缺点1、由于花键轴套与花键轴焊接为一体,当花键轴被锁舌锁住时,汽车停在有坡度的场地,方向轮受到的扭力较大,花键轴所连接的组件可以将扭矩传递到锁舌,将会使锁舌损坏或相关联的组件损坏,甚至使点火开关内的起动电路接通而点火,发生事故。另外,当花键轴套维修或更换时,需要破坏性拆除,维修或更换花键轴套不方便。2、花键轴上方与方向盘相连,方向盘上带有锥形套,锥形套外部安装有组合开关,其中包含有转向开关,转向开关与方向盘联 ...
