More Information
Summary:A chassis assembly of a vehicle includes an underbody and a subframe. A connector extends along an axis and connects the subframe and the underbody. A first wedge is fixed to one of the underbody and the subframe about the axis and a second wedge is fixed to the other of the underbody and subframe about the axis. The first wedge includes a protrusion and the second wedge defines a recess receiving the protrusion in a direction along the axis. During a frontal impact of the vehicle, the subframe may rotate relative to the underbody. During this rotation the first wedge and second wedge rotate relative to each other and the protrusion moves along the recess to apply a tensile load to the connection to break the connection.
