Abstract: The article deals with the synthesis of rational parameters of the telescopic front suspension and steering systems of a mining dump truck with payload capacity up to 240 tons. In order to meet the requirements of safety, energy efficiency and technological rationality of the developed systems, the parameters of the systems that largely determine the efficiency of the application of the developed equipment are formulated. In order to determine the rational parameters of suspension and steering system, the chassis and steering system of analog dump trucks were analyzed. The main tendencies in the layout of suspension units and load-bearing system, required dimensions of the chassis and maneuverability indicators were determined. For the system under development the kinematic parameters of turning were determined and the geometry of steering trapezoid was synthesized. The characteristics of pneumohydraulic springs (PHS) of the front telescopic suspension have been calculated and a solid-state model of PHS has been developed. The parameters of the hydraulic cylinders of the hydraulic steering system are determined taking into account the performance of the components of the hydraulic system of the dump truck and the requirements for the system speed. To evaluate the proposed solutions, a solid model of the front suspension and steering system was created.

Key words: suspension energy-efficient chassis design rational parameter synthesis maneuverability performance evaluation calculation of steering system components steering system quarry dump truck
