Abstract
A trailer suspension slider is provided that includes a suspension bogey. A trailer is supported on the suspension bogey and is longitudinally movable between a plurality of position relative to the suspension bogey. The trailer includes a stop bar to prevent the bogey from sliding out from underneath the trailer during braking if the pins are disengaged. A locking pin mechanism is movable between a locked position in which the locking mechanism couples the suspension bogey and the trailer in one of the plurality of positions and an unlocked position in which the trailer can move relative to the suspension bogey. The suspension bogey may collide violently with the stop bar when braking from a relatively low speed when the pins are unlocked. To this end, an energy absorption device is supported on either the trailer or the suspension bogey. The energy absorption device collapses in response to the stop bar engaging either the energy absorption device or the suspension bogey. Alternatively, an expandable cable may be used between the trailer and suspension bogey to slow the trailer as the stop bar approaches the suspension bogey.
