The invention discloses a passive tire air deflector and a vehicle, and relates to the field of automobile exterior trimming parts, the passive tire air deflector comprises a swing arm, a connecting rod and an air deflector, the swing arm is connected with a first swing arm rotating shaft, and the first swing arm rotating shaft is used for being rotationally connected with the vehicle exterior trimming parts; one end of the connecting rod is rotationally connected with the swing arm through a second swing arm rotating shaft, and the other end is rotationally connected with the air deflector through a connecting rod rotating shaft; when the air deflector is in a vertical state, the connecting rod rotating shaft, the first swing arm rotating shaft and the second swing arm rotating shaft are not located on the same straight line, and a set angle is formed between the center line of the connecting rod and the connecting line of the second swing arm rotating shaft and the first swing arm rotating shaft, so that the self-locking condition of the connecting rod is met. Complex control and execution mechanisms are not needed, and closing of the tire air deflector is controlled only through inertia force generated during braking; and the structure is simple, the cost is low, and the two performances of wind resistance and brake disc cooling are both considered.
本发明公开了一种被动式轮胎导风板及车辆,涉及汽车外饰部件领域,包括摆臂、连杆和导风板,所述摆臂连接第一摆臂转轴,第一摆臂转轴用于与车辆外饰部件转动连接;所述连杆一端通过第二摆臂转轴与摆臂转动连接,另一端通过连杆转轴与导风板转动连接;在导风板竖直状态下,所述连杆转轴、第一摆臂转轴、第二摆臂转轴不在一条直线上,且所述连杆的中心线和第二摆臂转轴与第一摆臂转轴的连线之间呈设定角度,以满足连杆自锁条件。本发明不需要借助复杂控制和执行机构,仅通过制动时产生的惯性力来控制轮胎导风板的关闭;结构简单,成本低廉,同时兼顾了风阻和刹车盘冷却两个性能。
