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.

Abstract: An energy dissipation system for a frame of a vehicle includes a frame rail including a crushable region and a non-crushable region. An energy dissipation device includes an energy transfer portion arranged partially in the crushable region and partially in the non-crushable region and configured to move in response to a vehicle impact on the frame rail. An energy dissipation portion is arranged within the non-crushable region, connected to the energy transfer portion. The energy dissipation device includes a first region connecting the energy dissipation portion to the non-crushable region, and a second region connecting the energy dissipation portion to the energy transfer portion. The first region of the energy dissipation portion is stiffer than the second region of the energy dissipation portion.

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 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 vehicle includes an underbody and a cradle assembly. The assembly includes a cradle body and a flange extending to a distal end portion. The distal end portion includes a platform having at least one side and defining an aperture spaced from the side. A fastener is disposed through the aperture and in engagement with the underbody when the cradle body is in a first position. The platform defines a void and has a portion of material disposed adjacent to the void to present a release pathway. The cradle body is configured to move from the first position to a second position which separates the flange of the cradle body from the underbody by moving the fastener out of the aperture, through the void and the portion of material along the release pathway, and out the side of the platform when the cradle body moves to the second position.

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 translation: 可释放接头被构造成将托架附接到能够受到外力的车辆的底部包括紧固件，托架的附接部分和部分套筒。 紧固件将摇篮连接到底部。 托架的附接部分包围紧固件，并且包括当外力超过阈值力时断裂的分离部分。 部分套筒附接到并设置在支架的附接部分内并且部分地环绕紧固件，以便形成开口，当分离部分断裂时，该开口提供用于紧固件移动通过以离开托架的水平路径。 当外力超过阈值力时，托架可以在可释放接头处与底座分离，在托架相对于底部没有垂直运动时。
