This is due to changes in the structure of the bus fleet. Conducted by LLC Zhizzahavtotransservis policy on replacement of the bus fleet, gasoline powered buses with diesel engine has a number of advantages. First, the reduced fuel costs. Second, use the buses with diesel engine economically advantageous due to the low fuel consumption car. Thirdly, a diesel engine compared to a carburettor, has less adverse environmental impact.

2.1 Selection and justification of the initial data
maintenance repair rolling stock
1. Initial data for calculation of accept a feasibility study. In the long term management of the enterprise provides fleet renewal and planned to purchase 60 buses ISUZU. Proceeding from the above calculations supremely proizvozhu for bus fleet of 121 buses:
. The design City - Jizzakh.
. Balance number of cars - 121 buses.
. Average daily mileage - 260 km
. Mileage since new - 1,6 thousand km
. Buses:
«ISUZU» SAZ NP - 3788 «ISUZU» SAZ NP - 2 125 «ISUZU» SAZ NP - 268
. Projected land-body section.number of days the rolling stock on the line adopted by 365 days. The number of buses on the line shifts receive one shift. Working hours 10:00 accept. Category for operation in hilly cities more than 100 thousand inhabitants accept III.
2.2 Calculation of the production program of maintenance
program MC maintenance is characterized by a number of technical services, planned for a certain period of time (year, day) .method of calculating production program involves selection and adjustment of frequency M - 1, M -2 and run to capital repair rolling stock designed for MC, payment number and capital repair for 1 car per cycle, that is to run the CD ratio calculation conversion from cycle to year and, based on counting the number of values ??obtained and capital repair per cycle for 1 car park for the whole year.MC plan on the basic parameters set for the calendar year, and production program for each type then rely on year. The program serves as a basis for determining the annual volume of work required MC and state workers.
Adjustments to regulatory periodicity maintenance and mileage to the capital repair. Mileage to the i-th species is then determined by the formula:
(1)
- standard mileage to the i-th type of maintenance;
coefficient taking into account the category of vehicle operating;
coefficient taking into account the climatic conditions;
К1=0,8; К2=0,9
to the average daily mileage proizvozhu follows:
where - average mileage, km;
the number of the capital repair, for one car per cycle. Specifies the number of overhauls and maintenance for one car per cycle using the following formulas:
Determining the number of maintenance for one car and the entire park for the year. Define technical readiness coefficient applied to the repair cycle by the formula:
dТОіТР - days of downtime in the maintenance and capital repair, day/1000 km to accept payments dТоіТР=0,30; - number of days of inactivity car capital repair accept DK=18 days.
Based on the calculated values ??of? T define pos...
