Aerodynamically deployable underbody strake

The invention provides an aerodynamically deployable underbody rim. The aerodynamically deployable underbody rim is provided. An aerodynamic control system for a vehicle may include an underbody shroud disposed at an underside of the vehicle, a tire assembly, and an actuator. The rim assembly may include one or more deployable rims operably coupled to the underbody shroud and having a deployed state in which the one or more deployable rims extend away from the underbody shroud to increase drag of the vehicle and reduce lift of the vehicle. The rim assembly may also have a retracted state in which the one or more deployable rims extend not away from the underbody shroud. The actuator may be operated by a driver of the vehicle while driving to transition the tire assembly from the retracted state to the deployed state. 本发明提供了"空气动力学可展开的车身底部轮箍"。一种用于车辆的空气动力学控制系统可以包括设置在车辆的下侧的车身底部护罩、轮箍总成和致动器。轮箍总成可以包括一个或多个可展开轮箍，所述一个或多个轮箍可操作地联接到车身底部护罩并且具有展开状态，在展开状态中，一个或多个可展开轮箍远离车身底部护罩延伸以增加车辆的阻力并减小车辆的升力。轮箍总成还可以具有缩回状态，在缩回状态中，一个或多个可展开轮箍不
