FIELD: transport.SUBSTANCE: rope weight transfer unit of a drive axle of a wheel-type tractor of the MTZ type includes a stiff power connecting rod attaching an agricultural implement to a towing hitch of the tractor, a flexible rope connection, a guide flywheel, a flanged polyspast assembly, a power hydraulic cylinder, a tractor hitch and a vertically rotating flat lever assembly. The lever assembly includes a bearing and is installed in the middle part of the torsion axle inserted in holes of gusset limit stops fixed with bolts on the tractor frame. One arm of the lever applies pressure to a power frame with a spring damper, which is installed under the housing of the controlled axle of the tractor of the MTZ type. The second arm of the lever is an operating lever, in the manufacturing hole of which a flexible rope connection is fixed, which passes with its other end through the guide flywheel and the flanged polyspast assembly, which are installed in the connecting rod of the agricultural implement, and is attached to a cross bar of tie-rods of the tractor hitch, which is controlled by the power cylinder of a hydraulic magnifying device of weight on drive axles of the tractor.EFFECT: increasing the passing ability, reducing slipping, improving safe operation and productivity of wheel-type tractors.5 dwg |
