Abstract
Improvements to a sliding sub-frame for heavy-duty vehicle suspensions include torque boxes, an air slider-pin system, and a heavy-duty shear-off nut. In the prior art, all four sliding pins are linked together with bars so if one sliding pin is stuck they are all stuck. Here, each sliding pin has a dedicated air assist bladder and is independent and can release on its own. That way, if one sliding pin is stuck, it is a much easier job to get it unstuck by moving the vehicle. The torque box relates to stress-relief measures of shear strains at critical fastened (eg., bolted) connections. The shear-off nut has a break-neck flanked between a hex head and collet nut. The clearance between the outside sidewall of the collet nut very nearly fully spans the space between the flats of a hex socket for the hex head, thereby providing light on-axis support.
