The invention discloses a trailer and a suspension system of the trailer, and belongs to the technical field of trailers, the trailer comprises a trailer frame, a traction pin is arranged at the front end of the trailer frame, cross beams are welded between the inner walls of the trailer frame at equal intervals in the width direction of the trailer frame, at least one set of wheels are symmetrically arranged at the center of the trailer frame, and supporting legs are arranged in front of the wheels; the suspension system of the trailer comprises a suspension, a trailer frame and wheels are connected through the suspension, a main shaft is arranged in the suspension, hubs are installed at the two ends of the main shaft, the wheels are connected to the hubs in a sleeved mode, and air dampers are symmetrically arranged at the front end of the main shaft. The connecting plate is additionally arranged at the bottom of the air suspension, so that the air spring can have supporting force during installation, the situation that the air spring is in an unstable state in the air suspension, the acting force of the air spring can be concentrated at a connecting point when the air spring is bumped, and consequently the connecting point deforms and cracks is avoided, and a supporting force is provided for the air spring through the connecting plate.
本发明公开了一种挂车及挂车的悬挂系统技术领域,属于挂车技术领域,挂车,包括挂车车架,挂车车架的前端设有牵引销,且挂车车架的内壁之间沿挂车车架宽度方向等距焊接有横梁,挂车车架的中心处对称至少设有一组车轮,车轮的前方设有支脚;挂车的悬挂系统,包括悬架,所述悬架将挂车车架与车轮进行连接,所述悬架内含有主轴,且主轴的两端均安装有轮毂,且车轮套接在轮毂上,所述主轴的前端对称设有空气减震器。通过在空气悬挂的底部增加连接板使空气弹簧在安装时能够有支撑力,避免空气弹簧在空气悬挂中处于不稳定状态,在受到颠簸时其作用力会集中在连接点处,造成连接点变形和开裂,通过连接板为空气弹簧提供一个支撑力。
