An arrangement for a motor vehicle includes a suspension arm, an engine cradle, a wheel attached to the suspension arm, at least one intermediate linking fork joint disposed between the suspension arm and the engine cradle to ensure attachment of the suspension arm to the engine cradle, removable elements to attach the linking fork joint to the engine cradle, elements to attach the suspension arm to the linking fork joint, and first fusible elements to allow a first relative displacement of the suspension arm with respect to the engine cradle over a first path only in an event of application, to the wheel or to the suspension arm, of an external force having a lateral component that exceeds a first predetermined threshold for which the first fusible elements are sized. The first fusible elements include at least one portion of the linking fork joint.
