Abstract: A structural arrangement for a vehicle includes a vehicle frame including a first frame member and a second frame member coupled to the first frame member. The vehicle frame extends along a vehicle body axis. The vehicle frame includes a suspension component including a control arm, a bushing, a bolt coupling the suspension component to the second frame member, and a load member coupled to the first frame member at a first attachment point and coupled to the second frame member at a second attachment point. The load member extends generally longitudinally along the vehicle body axis. The suspension component is coupled to the second frame member at the second attachment point and is detachable from the second frame member upon application of a load to the vehicle due to an impact event.

Abstract: A mount assembly for attaching a cradle to a vehicle frame includes an inner sleeve. The inner sleeve defines an inner sleeve aperture having a first aperture portion having a first diameter and a second aperture portion having a second diameter. The mount assembly also includes a bushing having a bushing body and configured to extend through the first aperture portion. The mount assembly additionally includes a fuse fixed to the bushing body to separate the first and second aperture portions. The mount assembly also includes a fastener configured to extend through the bushing body and an aperture in the vehicle frame for attaching the cradle to the frame. The fuse is configured to separate from the bushing body under a predetermined load to permit the fastener to shift from the first aperture portion to the second aperture portion and the cradle to shift relative to the frame.

Abstract: Suspension systems are provided where the lower control arm is allowed to separate from the engine cradle at prescribed conditions to deliver the proper wheel kinematics for select cases while maintaining structural integrity for all other load cases. A system includes a vehicle body structure, a wheel assembly, and a suspension system linking the wheel assembly to the engine cradle. The suspension system includes a link coupled with the engine cradle through a first joint and coupled with the wheel assembly through a second joint. The first joint is configured to release the link from the engine cradle under loads above a threshold force and above a threshold angle of the threshold force at the second joint, to provide the desired kinematics.

Abstract: A releasable joint configured to attach a cradle to an underbody of a vehicle subjectable to an external force includes a fastener, an attachment portion of the cradle, and a partial sleeve. The fastener attaches the cradle to the underbody. The attachment portion of the cradle encircles the fastener and includes a breakaway portion that fractures when the external force exceeds a threshold force. The partial sleeve is attached to and disposed within the attachment portion of the cradle and partially encircles the fastener so as to form an opening that provides a horizontal pathway for the fastener to move through to exit the cradle when the breakaway portion fractures. The cradle may separate from the underbody at the releasable joint with no vertical motion of the cradle relative to the underbody when the external force exceeds the threshold force.

Abstract: Systems are provided for suspensions that deliver desirable wheel kinematics at prescribed conditions. A system includes a vehicle body structure with an engine cradle, and an associated wheel assembly. A suspension system links the wheel assembly with the engine cradle, and includes a link coupled with the engine cradle and coupled with the wheel assembly. A joint at the link includes a flange that has an opening, an edge, and at least one undercut defined in edge of the flange. The joint allows release of the wheel assembly from the engine cradle by designed tearing between the opening and the at least one undercut. The release is initiated only under loads above a select threshold at the joint, to provide select kinematics of the wheel assembly for specific operational cases.

Abstract: A load impact management system for an automotive vehicle includes a load member extending from a first vehicle frame rail to a second vehicle frame rail and perpendicular to each of the first and second vehicle frame rails and to a vehicle body axis. The load member is coupled to the first vehicle frame rail at two attachment points and coupled to the second vehicle frame rail at two attachment points. The load member defines a load path between a first side of the automotive vehicle to a second side of the automotive vehicle opposite the first side and the load member is forward of a passenger compartment of the vehicle.

Abstract: A cradle assembly for a vehicle having an underbody is provided. The cradle assembly includes a cradle body attachable to the underbody of the vehicle by at least one fastener. The cradle body may define at least one pathway, which may have a first pathway portion and a second pathway portion between which the at least one fastener is movable. The at least one fastener may be positioned in the first pathway portion to enable the cradle body to be secured to the underbody, and in the second pathway portion to enable the cradle body to be separated from the underbody. The cradle body is configured to move with respect to the at least one fastener when an applied load on the vehicle is at or above a threshold magnitude.
