The trailer emergency braking auxiliary device comprises a supporting plate, the bottom end of the supporting plate is hinged to the side, close to a trailer head, of the upper end of a trailer plate, a containing cavity is formed in the side face of the supporting plate, a baffle is slidably connected into the containing cavity, and a spring is arranged in the middle of the position between the side face of the baffle and the side wall of the containing cavity. A buffering device is arranged between the side face of the baffle and the side wall of the containing cavity and comprises a first piston rod, a piston, a first damping pipe, a first damping box, a second damping pipe, a second damping box and a second piston rod, and anti-roll devices are symmetrically arranged on the two sides of the bottom end of the trolley plate. According to the trailer emergency braking auxiliary device, energy is absorbed through gas pressure and deformation of the spring, inertia of goods is buffered, a tractor in front is protected, and the safety of the trailer in the traveling process is improved as much as possible.
本发明公开了一种挂车紧急制动辅助装置,包括支撑板,所述支撑板底端铰接在车板上端靠近车头的一侧,所述支撑板侧面设置有容置腔,所述容置腔内滑动连接有挡板,所述挡板侧面与容置腔侧壁之间中部设置有弹簧,所述挡板侧面与容置腔侧壁之间设置有缓冲装置,所述缓冲装置包括第一活塞杆、活塞、第一减震管、第一减震箱、第二减震管、第二减震箱和第二活塞杆,所述车板底端两侧对称设置有防侧倾装置。该种挂车紧急制动辅助装置通过气体压强以及弹簧的形变对能量进行吸收以及对货物的惯性进行缓冲,保护前方的牵引车,尽量提高挂车行驶过程的安全性。
