METHOD OF DETERMINING TRACTION-POWER PARAMETERS OF TRACTORS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC G01M17/00 

FIELD: agriculture.

SUBSTANCE: in process of determining the traction-power parameters of tractors the adjustable horizontal force of resistance to movement of the test tractor is provided. At the same time the rear drive axle is loaded fully, creating an adjustable vertical load on the cross-element of the drawbar hitch of the rear linkage or a hydrohook. In addition, the test tractor engine is loaded with an adjustable resistive torque through its PTO shaft, and the values of the traction-power parameters and the parameters of loads with different gears of transmission and backgrounds of farm works are registered. The device for determining the traction-power parameters of tractors comprises the strength measuring equipment, a loading tractor, the front linkage of which is connected by a cable with the cross-element of the drawbar hitch of the rear linkage or a hydrohook of the test tractor and a traction uniaxial frame. In the side members of the frame inner space the load is placed with the ability to move, and on top of the frame a pneumatic braking device is fixed, connected through a hinge cardan shaft with the PTO shaft of the test tractor.

EFFECT: increase in efficiency of use of expensive equipment.
