The invention discloses a split type wind resistance braking device and a vehicle braking system thereof. The split type wind resistance braking device comprises two wind resistance plates arranged oppositely, a spring damping actuator, a driving connecting rod transmission mechanism, a locking mechanism, an auxiliary opening mechanism and a main body frame. The main body frame is provided with a mounting interface connected with a train and is mounted at the top of the train. The two wind resistance plates and the rotating shafts are oppositely arranged, the rotating shafts and the wind wing plates are installed on the main body frame and rotate around the corresponding rotating shafts, and then the two wind resistance plates can be opened and closed in the independent shaft rotation direction. According to different running directions of the train, each unit opens the wind resistance plate on one side in a staggered mode, and the wind resistance plate on the other side only opens a tiny angle under the action of pneumatic pressure after being unlocked. The area of a single wind resistance plate is larger, the total area of the wind resistance plates is close to the projection area of a unit, and the space utilization rate is higher; and meanwhile, the series connection aerodynamic efficiency of the wind resistance plates can be effectively improved in the mode of opening the wind resistance plates in a staggered mode.

    本发明公开了一种对开式风阻制动装置及其车辆制动系统,包括对向布置的两个风阻板、弹簧阻尼作动器、驱动连杆传动机构、锁闭机构、辅助开启机构以及主体框架。所述主体框架设置与车辆连接的安装接口,供安装于列车的顶部。所述对向布置的两个风阻板以及转轴,所述转轴所述风翼板安装于所述主体框架并绕各自所述转轴转动,进而两个风阻板能够独立的轴转方向启闭。根据列车行驶方向不同,每个单元分别交错式的打开一侧的风阻板,另一侧的风阻板解锁后在气动压力的作用仅打开一个微小的角度。本发明单块风阻板的面积更大,且风阻板的总面积接近单元的投影面积,空间利用率更高;同时这种交错式打开风阻板的方式,能有效提高风阻板的串联气动效率。
