Ensuring the safety of operation of the truck with the semi-trailer

Abstract

This article raises an important issue of road train stability under various operating conditions, it also discusses one of the elements of active safety in the operation of road trains consisting of a truck tractor and a semi-trailer, namely the ordering of the mutual position of the parts of the train. A brief overview of the principle of operation of various schemes designed to prevent the folding of a tractor with a semi-trailer, as well as structural and functional capabilities, some disadvantages and advantages is given. The new and one of the latest implementation systems for blocking the folding of a trackless vehicle consisting of a semi-trailer is presented. The blocking mechanism for folding a train includes a closed kinematic chain using flexible coupling, as well as a controlled closed hydraulic system. There are certain promising possibilities of this proposed technical solution in terms of increasing active safety in the operation of the trailer and organizing the provision of controllability of the saddle tractor relative to the semi-trailer interconnected with the steering and steering wheels, with the position of the brake pedal sensor road trains, with driver’s actions, weather conditions and traffic situations.
