a result of frictional forces (abrasion), exposure to high temperatures, metal fatigue and chemical effects of various gases, acids and alkalis.to comply with regulations governing causes premature wear of the main reasons for which are: non-compliance running car, untimely and poor maintenance, fast driving on bad roads, failure to comply and start the engine warms up, the use of unsuitable varieties of oils and lubricants.influence on the wear parts have driving mode, road and weather conditions, fuel quality, lubrication, maintenance and driving skills.justifying the optimum mode the car is a list of operations is determined by the coefficient of repeatability, the frequency is set by statistical data path of a vehicle to an acceptable parameter value node unit. Since the mileage limit to the node status is random, the large scatter in the data, and therefore to reduce costs to the receiving frequency is more than the minimum, taking into account the confidence level of probability. At the same time a certain portion of vehicles needed at the specified intervals before, and the overwhelming majority - later. To reduce cost and increase reliability maintenance necessary to carry out work, when the parameter reaches the allowable value. And this is only possible with timely and accurate determination of the technical condition of the car without disassembling. Technical control, which is mainly produced the motor company visually insufficiently effective, evaluation of technical condition depends on the skill of the controller. For objective monitoring devices are necessary, that can be used to identify vehicles that pose a risk at the same time avoiding removing serviceable unit. Instrumental determination of the technical state of the node, without disassembling the unit called diagnosing.condition of the car is characterized by structural parameters (clearance, center-distance, deflection, displacement, linear dimensions, surface state of mating parts, etc.). Interaction of car with the environment and mechanical loading lead to a change of its technical condition. Changes in structural parameters of aggregates car has certain regularities.these problems peculiar and Jizzakh regionon the foregoing, the subject of my final qualifying work find relevant and useful.aim of this work is the final qualifying justification optimal mode the car is on the LLC laquo ; Otabeksupertrans (LLC Zhizzahavtotransservis ) increase the efficiency of activity of Otabeksupertrans »(LLC« Zhizzahavtotransservis ) and successful activities should be solved the following problems:
Development of the motor cjmpany production building sites with the location of existing data and the number of cars;
Development and introduction of a 6-rack lift buses with placing it in the Touring Car division;
Development of working drawings lift;
Describe the principle and the main characteristics of the lift;
Description of possible faults lift and troubleshooting.
