Abstract
Keywords: influence, reliability, steering gear, utility car, lorry, quantitative and qualitative indicators, operational time.
The paper analyses the influence of the vehicle's type and that of the exploiting conditions upon the reliability of the steering gear. In this certain sense it has developed a theoretical study proper through the description of the main causes that produce the degradation processes in the system's components. With the help of reliability indicators, the experimental research has established the importance of respecting the technologic discipline during the production process and the necessity of modernizing the roads, in order to eliminate extreme solicitation from the steering gear's elements.
