History
In 1976, the All-Union Design and Experimental Institute of Bus Engineering developed the terms of reference for the creation of a new model of the LAZ-5255 tourist bus with a KamAZ diesel engine, designed to replace the LAZ, taking into account the experience of the previously created experimental LAZ "Ukraine-73" experimental model -699 N [1] . The bus was originally developed as part of a new unified family of buses (which included the average city bus LAZ-4202 , suburban bus LAZ-42021, large city buses LiAZ-5256 and LiAZ-5256M and tourist buses LAZ-5255) [2] .
In 1978, several experimental bus options were made by the forces of the experimental workshop: [1]
- 43-seater bus (offered as standard) [1]
- 40-seater option (equipped with a wardrobe for storing passengers' outer clothing) [1]
- 30-seat option (equipped with wardrobe, bar and table with four seats) [1]
- 28-seat option (equipped with wardrobe, bar, table with four seats, toilet and air conditioning ) [1]
In addition, for each option, a “Lux” version was provided (which provided for the installation of a TV , VCR and radiotelephone ) [1] .
The first two LAZ-5255 buses were sent for trial operation in Moscow, they were used during the 1980 Olympic Games [2] .
After completion of state tests, in 1980 the LAZ-5255 was recommended for production (by this time, the bus resource before maintenance of TO-1 was 5000 km, before maintenance of TO-2 it was 20,000 km) [1] .
In 1981, the experimental operation of the LAZ-5255 was completed with positive results [3] .
In 1983, a decision was approved to manufacture the bus in two versions (43-seater and 28-seater) [2] .
In 1984, at the Autoprom-84 exhibition, the plant introduced the LAZ-5255 intercity bus [4] .
By 1991, the bus was prepared for mass production. In the future, a more simplified version of the LAZ-5207 was produced instead.
Description
The bus is a two-door, cabless, rear-mounted diesel engine, high-floor (a luggage compartment with a capacity of 6.7 m³ is located under the passenger compartment floor) [1] .
Superior cabin, with a liquid heating system (heating was provided by three heaters located on the sides and in the rear of the cabin), the ventilation system included six fans and an air intake on the roof) [1] .
Three emergency hatches of 600 × 800 mm were equipped in the roof of the bus [1] .
Since the bus was created under the program of industrial cooperation between the USSR enterprises and the CMEA countries , the design used a driveshaft from MAZ-500 and a two-stage bridge with final drives manufactured by the Hungarian company Raba (unified with the bridge of the Ikarus buses that were in operation in the USSR) [ 1] .
Options and Modifications
- In the 1980s, on the basis of LAZ-5255, special buses LAZ-5255P and LAZ-5255P1 were designed and built to deliver astronauts and launch personnel to the launch site of the Baikonur Cosmodrome [5] .
