Improvement of suspension system of mobile power units
Abstract
Original designs of pneumatic-tyre movers and vehicle suspension are proposed. Their use will permit to increase reliability, operation durability, ride comfort, and cross-country capability of machine and tractor unit; to improve operator work conditions; to decrease vertical vibration and dynamic loads on supporting surface as well as soil compaction.
