AIR SPRING ACTUATED SLIDER FOR SEMI-TRAILER

An air spring actuated slider pin release system for a semi-trailer slider includes an actuator shaft oriented to extend in generally parallel relationship to at least one of a pair of parallel main members, being connected to the slider for axial rotation, and having a transverse lever arm secured to each end of the shaft for common rotation. Each lever arm has an end connected to a retractable,biased lock pin via a link so that rotation of the shaft and the lever arms causes retraction of the associated lock pin relative to the main member. The actuator shaft has a normally projecting air spring bracket. An air spring is disposed between one of the main members and the air spring bracket so that inflation of the air spring acts on the air spring bracket, axially rotating the shaft and the lever arms for retracting the lock pins. 种用于半挂车滑块的空气弹簧致动的滑块销释放系统，包括：致动器轴，其被定向成以与对平行的主构件中的至少个大体上平行的关系延伸，其被连接到所述滑块用于轴向旋转，并且具有个被固定到所述轴部的每端的横向杠杆臂，用于共同旋转。每个杠杆臂的端部经由连杆被连接到可缩回的偏置的锁定销，使得轴和杠杆臂的旋转导致相关联的锁定销相对于主构件缩回。致动器轴具有正交突出的空气弹簧支架。
