Abstract: The present invention is directed to a hub lock assembly for rotatably fixing a hub to a selectively powered rotating member. The hub lock assembly comprises a hub including a barrel having a bore therethrough defining internal splines. The hub lock assembly also comprises a spindle having a distal end defining external splines disposed within the barrel of the hub for rotatably supporting the hub. The spindle is adapted to be connected for rotation with the powered rotating member. The hub lock further comprises an actuator for switching the hub lock assembly between an engaged position where hub is rotatably fixed to the spindle and a disengaged position where the hub is free to rotate relative to the spindle. The actuator comprises a body member defining external splines and having a bore therethrough defining internal splines.

Abstract: A deformable panel member is provided for absorbing the energy of a moving object impacting the panel member. The panel member is adapted to be connected to a rigid member and has a front wall, a rear wall and two side walls extending between and interconnecting the front and rear walls. A support member in panel member extends between and interconnects at least two of the walls. The side walls are adapted to be angled relative to the rigid member in a direction of movement of the object when the panel member is mounted to the rigid member. An impact on the panel member will tend to deform the panel member toward the rigid member in the direction of movement of the object. This deformation allows the panel member to absorb the energy of the object for decelerating and redirecting the object subsequent to impact. An energy absorbing barrier is also provided comprising a plurality of the panel members mounted at spaced intervals along the rigid member.
