Designs of power steering gears with a reaction effect are used in off-road trucks. In this article the author investigates a regulating system for reaction effect of hydraulic type power steering gear of a cross-country cargo carrier and justified the characteristic for the regulating system of hydraulic booster reaction effect. The author also introduced a concept of coefficient of informativeness. The mathematical model of steering control and the numerical experiment method were used. The author proposes a regulation method allowing to neglect reactive elements and simplify the design. The results presented in this paper could be used for developing perspective steering systems for trucks which are similar to those discussed and operating under similar conditions.

Design and parameters of steering system are the main factors of maintaining controllability and stability of the vehicle. The subject of this paper is the steering system of a three-axle vehicle with steered front and rear wheels. Calculated relations for determination of the required ratio between the front and rear steered wheels’ rotation to ensure controllability and stability of a car were obtained. Recommendations on control parameters for wheel turning were drawn; a new steering control scheme was also proposed. The results presented in this paper can be used for upgrading off-road trucks which are similar to those discussed and operating under similar conditions.
