The invention provides a non-power steering frame and a rail train. The non-power steering frame comprises a framework, three groups of wheel sets, a traction mechanism and a damping mechanism; the drawing mechanism comprises a central pin, a shaft sleeve, an installation base and two traction rods; the central pin is inserted inside the shaft sleeve; the middle of the installation base is provided with an installation hole; the shaft sleeve is arranged inside the installation hole; the traction rods are hinged between a cross beam of the framework and the installation base; a hinging axis between the traction rod and the cross beam is perpendicular to a hinging axis between the traction rod and the installation base; the damping mechanism comprises an air spring, a vertical damper, a transverse damper and a serpentine resistance damper; bilateral sides of the upper surface of the framework are respectively provided with the air spring and the transverse damper; the transverse damper is horizontally arranged; bilateral sides of the framework are provided with the vertical damper and the serpentine resistance damper; the vertical damper is vertically arranged; the serpentine resistance damper is horizontally arranged. According to the non-power steering frame, maintenance is convenient and the integral weight is reduced to satisfy high-speed operation requirement for shaft weight.
