Independent work prepared by Boltayeva Ziyoda, a 3rd-year student of Fergana Polytechnic Institute, Faculty of Mechanics and Mechanical Engineering, on the topic "Longitudinal cars in normal stagnation"

There are many things that change during the use of the car Among the factors, the ones that mainly affect its stability are tires and is the technical condition of the braking system. Tire treads are eaten away As you go, the bite gets worse and the speed increases or the possibility of being pushed to the side increases when braking. Tire patterns gear ratio of a completely lost wheel, to a new one almost twice less than Grip to prevent skidding on slippery roads it is good to brake the car without disengaging the mechanism gives, because of the rotating leading wheels the fact that the engine is connected to the gi is their blocking resists.

The development of automobile technology and its operational features The researcher depends on the improvement of scientific sources. Including each The compliance of the construction with operational requirements is a new feature of automobile technology ensures promotion to the next level. That is why in the field of automobile transport active scientific research departments, project design bureaus, scientists and researchers at relevant higher educational institutions in the country advanced motor vehicle by studying the specific features of operation experiences of enterprises, engineers, technicians and drivers generalize, newly created or modified vehicles develop the necessary requirements for the basic rules of automobile theory to practical issues related to improvement and their precise exploitation work on implementation.

Classification of operating characteristics. The theory of operational characteristics of the car, transport movement theoretical mechanics is a science that studies the laws and operational characteristics, based on such sciences as machine and mechanism theory, material resistance. Operation of the car based on theoretical research and experimental data Factors affecting its characteristics are identified and the car design is improved Theory of operational characteristics of cars 11 ways of improvement have been found, while this science optimizes the cargo transportation process also solved the issues of organization and maximum economic efficiency. The theory of operational characteristics of the car during its use the methods of effective use of the car and operational design characterizes the degree of satisfaction of requirements. Operating characteristics are the actual operating conditions of the vehicle refers to the level of adaptation and their ease of use and efficiency determines. Operating characteristics of the vehicle, that is, the vehicle mainly divided into two groups: 1) features related to movement; 2) static, i.e. characteristics that do not depend on movement.
