A system for managing wheel kinematics during a collision event includes a break-away region for releasing a joint of a lower control arm. The system includes a recess arranged in a frame member, and a pin arranged vertically in the recess and configured to couple the lower control arm to the frame member. The break away region includes a reduced stiffness and is configured to fail under the collision event to allow the pin to move laterally out of the recess. The recess may be formed by a top plate and a bottom plate or a C-shaped bracket, which include through features to accommodate the pin. The break-away region includes a first notch and a second notch that reduce a stiffness of the structures that form the recess, thus allowing the pin to be released under a predetermined loading. The break-away region may fracture to release the pin. 一种用于在碰撞事件期间管理轮运动学的系统包括用于释放下控制臂的接头的脱离区域。所述系统包括：凹部，所述凹部布置在框架构件中；以及销，所述销竖直地布置在所述凹部中并且配置成将下控制臂联接到所述框架构件。所述脱离区域包括减小的刚度，并且配置成在碰撞事件下失效以允许所述销从所述凹部横向移出。所述凹部可以由顶板和底板或C形托架形成，所述顶板和底板或
