The invention relates to an automobile safety braking auxiliary device which comprises an automobile body, the automobile body comprises a rear axle, an axle is installed on the rear axle, the automobile safety brake auxiliary device further comprises a driver, a controller and an auxiliary speed reducing mechanism, and the auxiliary speed reducing mechanism comprises a friction ring arranged on the axle in a sleeving mode, a first brake arm, a second brake arm arranged in a crossed mode with the first brake arm and a rotating shaft. A first center hole is formed in the first brake arm, a second center hole is formed in the second brake arm, and the rotating shaft penetrates through the first center hole and the second center hole; the driver is connected with the auxiliary speed reducing mechanism and used for driving the first brake arm and the second brake arm to move to be matched with the friction ring so as to assist braking, and the controller is in signal connection with the driver and controls the driver to act. The angle between the first brake arm and the second brake arm is changed through the driver, so that the first brake arm and the second brake arm are clamped or loosened towards the friction ring, larger braking force borne by an automobile in the braking process can be increased, and the purpose of shortening the braking distance of the automobile is achieved.
本发明涉及一种汽车安全制动辅助装置,包括车体,车体包括后桥,后桥上安装有车轴,还包括驱动器、控制器和辅助减速机构,辅助减速机构包括套设在车轴上的摩擦圈、第一制动臂、与第一制动臂交叉设置的第二制动臂和转动轴,第一制动臂上设有第一中心孔,第二制动臂上设有第二中心孔,转动轴穿过第一中心孔和第二中心孔;驱动器与辅助减速机构连接,驱动器用于驱动第一制动臂和第二制动臂运动与摩擦圈配合以辅助刹车,控制器与驱动器信号连接并控制驱动器动作。通过驱动器改变第一制动臂和第二制动臂之间的角度,进而使第一制动臂和第二制动臂向摩擦圈抱合或松开,能够增加汽车在刹车过程中受到更大的制动力,从而实现了缩短汽车制动距离的目的。
