The invention provides a trailer chassis capable of being dragged and self-propelled, and mainly relates to the technical field of trailer chassis. A trailer chassis capable of being dragged and self-propelled is characterized in that the trailer chassis adopts a driving structure that a front axle can be steered by wheels and a rear axle has power, a traction rod is hung on a tractor and runs along with the tractor when the trailer chassis is dragged, a hydraulic inertia braking system is adopted for service braking during dragging, and when the trailer chassis is switched to a self-propelled state, the traction rod is driven by the hydraulic inertia braking system to run along with the tractor. Power is switched to a rear axle driven by a motor or an oil motor through a gear shifting handle, the rear axle drives a trailer chassis to walk, a front axle steers through a hydraulic oil cylinder or an electric push rod, and braking is conducted through an electric control brake pump. According to the invention, a power and steering system is added to the trailer in a relatively economical form, so that the trailer can run autonomously, and the power and steering system can be disconnected very conveniently during dragging, so that the trailer can be dragged quickly in a long distance, and different trailer use scenes can be better met.

    本发明提供一种既可拖行又可以自行走的挂车底盘,主要涉及挂车底盘技术领域。一种既可拖行又可以自行走的挂车底盘,挂车底盘采用前轴可轮转向,后轴带动力驱动结构,牵引杆在挂车底盘拖行时挂接到牵引车上,跟随牵引车行驶,拖行时的行车制动采用液压惯性制动系统,挂车底盘切换到自行走状态时,通过换挡手柄把动力切换到由电机或者油马达驱动的后轴上,由后轴驱动挂车底盘行走,前轴通过液压油缸或者电推杆进行转向,由电控刹车泵进行制动。本发明通过一种比较经济的形式给挂车增加动力及转向系统,使挂车可以自主行驶,并在拖行时可以很方便地断开动力及转向系统,快速长距离地拖行,以更好地满足不同的挂车使用场景。
