Methodology for calculating indicators of braking stability of road trains

Abstract

The article discusses the stability of road trains with four-wheel drive tractor-trailers during braking. The existing methods of ensuring the stability of braking of road trains with non-four-wheel drive tractors in relation to road trains with four-wheel drive tractor vehicles are ineffective, due to the fact that they have a number of significant design features that do not allow them to distribute the results of the studies carried out on road trains with non-four-wheel drive tractor vehicles.

The authors propose a methodology for calculating the indicators of braking stability of road trains with four-wheel drive tractor vehicles, which is based on the possibility of taking into account the patterns of distribution of braking torque by methods adopted in the theory of force flow with differences in the implementation of braking forces on tractor wheels.
