FIELD: transport.SUBSTANCE: invention relates to transport facilities and may be used at farms and in forestry. Proposed traveler comprises two traveling propulsors wherein every linkwork ensures foot straight travel, rocker mechanism allows fast transfer of the foot and hydraulic mechanism extends the foot and lock it to follow ground relief. Body has top and bottom openings, each being communicated via end check valve with appropriate chamber to be open by piston into adjacent chamber at appropriate piston extreme position. Main level axle is furnished with main piston to form front and rear chambers with main housing. Slide valve is arranged at crank axle. In common body said slide valve has groove for connection of twin central slot with left or right slides arranged on main lever axle side in 1and 2quarters of slide circular path. Housing space is communicated via hydraulic control valve with inlet holes with at half-step position and, at stepless travel, with inlet grooves. Hydraulic control valve at step travel is closed. Pump outlet is connected with right main housing rear chamber.EFFECT: higher flotation and traction force, smooth travel.6 dwg |
