The invention belongs to the technical field of vehicle operation control, and discloses an unpowered vehicle comprising a dragging damping system, which comprises the dragging damping system, a chassis, wheels and a shaft, the shaft penetrates through the chassis and is in clearance fit with the chassis; the two ends of the shaft are fixedly connected with the wheels respectively; the dragging damping system comprises an inner wheel disc, an inner damping ring, an outer damping ring and a damping fixing plate; the damping fixing plate is fixed to the chassis, the inner damping ring is located in the outer damping ring, and the inner wheel disc is arranged in the inner damping ring. The inner ring of the inner damping ring and the circumferential face of the inner wheel disc are each provided with a circle of ratchets. A waist-shaped through hole is formed in the inner wheel disc; a through hole A is formed in the damping fixing plate, the shaft sequentially penetrates through the through hole A and the kidney-shaped through hole, and the shaft is in clearance fit with the through hole A. The safety risks of unhooking, squeezing, drifting, overturning and the like caused by out-of-control posture of the motor-free car due to acceleration or deceleration of the tractor are avoided, and the problems of impact or collision between the motor-free car and the tractor due to inertia are solved.

    本发明属于车辆运行控制技术领域,公开了一种包含拖拽阻尼系统的无动力车,包括拖拽阻尼系统、底盘、车轮和轴;轴穿过底盘,并与底盘间隙配合;轴的两端分别和一个车轮固定连接;拖拽阻尼系统包括内轮盘、内阻尼圈、外阻尼圈和阻尼固定板;阻尼固定板固定在底盘上,内阻尼圈位于外阻尼圈内部,内轮盘设置在内阻尼圈的内部;内阻尼圈的内圈和内轮盘的周面上均设有一圈棘齿;内轮盘上设有腰形通孔;阻尼固定板上设有通孔A,轴依次穿过通孔A和腰形通孔,且轴与通孔A间隙配合。本发明避免了因牵引车加速或减速而导致无动车出现姿态失控产生脱钩、挤兑、甩尾、倾覆等安全风险,以及因惯性与牵引车发生冲击或碰撞的问题。
