Rational operation of existing and design of new designs of self-propelled wheeled
vehicles is impossible without a theoretical analysis of their performance properties. In particular,
the operation of such machines in heavy road conditions is relevant such operational properties as
their traction patency. Given the fact that the operating conditions of self-propelled wheeled vehicles
differ in a variety of different road conditions, the correspondence of their traction patency to such
conditions will determine the efficiency of their work. The analysis of the operating conditions of
all-wheel drive self-propelled machines showed that one of the factors that reduce their efficiency
are restrictions on traction patency due to the occurrence of power circulation in their transmission.
Therefore, the paper formulates the requirements for traction patency of self-propelled wheeled
vehicles. Further, the approach to estimate the redistribution of traction forces on the wheels of
self-propelled machines is justified. To establish a direct connection between the traction patency of
self-propelled machines on the one hand and the processes of power circulation in their transmission
on the other hand, it is proposed to link the processes of calculating the parameters of the front and
rear drive wheels of the machine, taking into account the reduced inertia force of the corresponding
wheels with the process of assessing the redistribution of traction forces on their wheels. In the
end, the equations for calculating the parameters of traction permeability of the front and rear drive
wheels of the machine taking into account the reduced inertia force of the corresponding wheels are
justified and obtained.
