FIELD: machine building.
SUBSTANCE: invention relates to automotive industry. Method of measuring traction forces consists in creating adjustable force of resistance to tested tractor movement. Values of obtained load parameters are recorded. For certain type of tractor simultaneously for each of load indicators maximum temperature on surface of discharge pipe, parameters of microclimate and traction force on hook of tractor are measured. Alignment chart of dependence of discharge pipe temperature from load indicators, index of heat load of environment and traction force on hook of tractor is plotted. In field conditions maximum temperature of surface of discharge pipe is measured and actual traction force of tractor is determined using nomogram.
EFFECT: reduced time for determination of actual load of tractor.
