The invention discloses a parking brake wire drawing mechanism. The parking brake wire drawing mechanism comprises a shell, a wire drawing assembly, an adjusting wire drawing sheath and an adjusting assembly; a mounting cavity extending in the front-back direction is formed in the shell; the wire drawing assembly comprises a wire drawing extending in the front-back direction, and the wire drawingis movably installed in the mounting cavity in the front-back direction; the adjusting wire drawing sheath is arranged on the wire drawing in a sleeving mode, and one end of the adjusting wire drawingsheath is movably installed in the mounting cavity in the front-back direction; and the adjusting assembly is arranged in the mounting cavity and is in drive connection with the wire drawing sheath so to drive the adjusting wire drawing sheath to move. The adjusting wire drawing sheath is driven by the adjusting assembly to move so that the adjusting wire drawing sheath can move away from the mounting cavity, the adjusting wire drawing sheath on a parking wire drawing outer sheath is automatically adjusted, the length between the wire drawing end head and the outer sheath is reduced, the freestroke of a parking brake swing arm is reduced, the workload of an operator is reduced, and the operation is simple.
本发明公开一种驻车制动拉丝机构,包括壳体、拉丝总成、调整拉丝护套及调节组件,壳体形成有沿前后向延伸设置的安装腔,拉丝总成包括沿前后向延伸设置的拉丝,拉丝沿前后向活动安装于安装腔,调整拉丝护套套装于拉丝,调整拉丝护套的一端沿前后向活动安装于安装腔,调节组件设于安装腔,与拉丝驱动连接,以驱动调整拉丝护套活动,通过调节组件驱动调整拉丝护套活动,使得调整拉丝护套远离安装腔活动,实现了自动调节驻车拉丝外护套上的调整拉丝护套,减少拉丝端头与外护套间的长度,降低驻车制动摆臂的自由行程,减轻了操作者的工作量,操作简单。
