TOWED VEHICLE Russian patent published in 2008 - IPC B60P3/40 B60P3/41 B62D21/20 B62D21/02 

FIELD: transport.

SUBSTANCE: invention relates to vehicle production, particularly, to towed vehicles used incorporated with self-propelled vehicles intended for transportation of, for example, timber. The towed vehicle incorporates a frame made up of lengthwise beams jointed by cross bars, running wheels, a bearing rotary device arranged beneath the frame lower front part and linked to the front wheels, a hitch arranged beneath the frame lower front part and linked to the bearing rotary device, a cargo compartment with its width exceeding the frame width made up of bolsters arranged consecutively along the frame lengthwise beams, every bolster incorporating a transverse beam making a bolster load-carrying base and vertical props linked to the said bolster base on the side of its cantilever end faces. The frame lengthwise beams are made up of two interconnected upper front and lower rear parts arranged consecutively and stepwise. The upper part is arranged above the bearing rotary device. Cross bar or cross bars linking the frame lengthwise beams forms or form the upper step bolster load-carrying base and incorporates sections extending in cantilever beyond the surfaces of the said frame part lengthwise beam outer cross bars. The said frame part lengthwise beams are furnished with lower horizontal shoulders symmetric about the beams lengthwise axes and jointed to the beams to form the bearing surfaces for the cross bar and its cantilever sections, the said surfaces width not exceeding the length of the cross bar cantilever sections.

EFFECT: complex interaction between loading/unloading equipment with the trailer and higher reliability of the latter.
