    • An anti-theft steering shaft lock on an automobile steering column includes a keeper rotatable as a unit with a steering shaft of the steering column, a dead bolt slidable into and out of a slot in the keeper to immobilize the steering shaft, a transmission shift lever rotatable about a transverse axis of the steering column, a connecting rod between the shift lever and the dead bolt for withdrawing the dead bolt from the keeper slot when the shift lever is rotated from a PARK position to an operating range position, and a blocker on the steering column connected to an ignition lock on the steering column operative to prevent withdrawal of the dead bolt from the keeper when the ignition is locked. The mechanical advantage attributable to the length of the shift lever affords relatively effortless withdrawal of the dead bolt from the keeper against residual torque induced friction between the dead bolt and the keeper slot.
    • 汽车转向柱上的防盗转向轴锁定装置包括一个可转向作为一个单元的转向柱的转向轴的保持器,一个能够进入和退出保持器中的一个狭槽的固定螺栓以固定转向轴, 所述杆可绕所述转向柱的横向轴线旋转,所述连接杆位于所述变速杆和所述止动螺栓之间,用于当所述变速杆从公差位置旋转到操作范围位置时将所述止动螺栓从所述保持器槽中取出, 在连接到转向柱上的点火锁的转向柱上,可操作以防止当点火锁定时死栓从保持器中撤出。 由于变速杆的长度的机械优点使得死栓从保持器相对轻而易举地抵抗残余扭矩引起的死栓和保持器槽之间的摩擦。
