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.
