The invention provides a vehicle choke plate and an automobile. The vehicle choke plate comprises a first windward plate, a second windward plate and a third windward plate, wherein the first windward plate is used for shielding a suspension of the automobile on the windward side; the second windward plate is used for shielding the side, close to the suspension, of wheels of the automobile on the windward side; wherein the first windward plate and the second windward plate are connected through a transition section; the second windward plate is fixedly connected with the third windward plate; the first windward plate is provided with a first end and a second end which are opposite in the width direction; the vertical distance from the first end to the second windward plate is greater than the vertical distance from the second end to the second windward plate; the first windward plate is located on the side, away from the vehicle head, of the second windward plate. The first end is the end where the first windward plate is connected with the transition section. According to the technical scheme, under the action of the vehicle choke plate, the direct impact of airflow on the suspension and the wheels is reduced, and the flow field of the wheels and the suspension area is improved, so that the wind resistance coefficient of the vehicle is reduced, and the endurance mileage of the vehicle is increased.
本申请提供了一种车辆阻风板及汽车,该车辆阻风板包括:用于在迎风侧遮挡车辆的悬架的第一迎风板,用于在迎风侧遮挡车辆的车轮靠近悬架一侧的第二迎风板,以及用于在迎风侧遮挡车轮远离悬架一侧部分区域的第三迎风板;其中,第一迎风板与第二迎风板通过过渡段连接;第二迎风板与第三迎风板固定连接;第一迎风板具有沿宽度方向相对的第一端及第二端;其中,第一端到第二迎风板的垂直距离大于第二端到第二迎风板的垂直距离;第一迎风板位于第二迎风板背离车辆的车头一侧;第一端为第一迎风板与过渡段连接的一端。在上述技术方案中,在车辆阻风板的作用下,气流对悬架和车轮的直接冲击减少,改善了车轮与悬架区域的流场,从而减小了车辆风阻系数,提升了车辆续航里程。
