ON THE QUESTION OF CREATING A TRAILER BUS TRAIN

Abstract

Hinged buses and bus trains are usually operated in large cities with heavy traffic. Therefore, the traction and speed properties of bus trains should be at the level of single buses. Among the 13 indicators of traction and speed properties that assess the dynamics of the road train, the most important are maximum speed, acceleration during acceleration, time and path of acceleration to maximum speed, acceleration time on the path of 400 and 1000 m. road trains. The A70132 diesel bus and the A701 electric bus were selected as the object of the study when working with the trailer. A comparative assessment of these buses on the indicators of traction and speed properties. It was found that the use of electric buses to create a bus train is problematic in view of the lack of traction in the area of high loads due to the acceleration of the bus. However, for a bus with diesel there is a significant reserve of traction in lower gears, due to the operation of the torque converter. The efficiency of using such a bus train when working on urban routes, where there is a limit on the maximum speed at 50 km / h. If the speed increases to 70 km / h, the use of a bus train consisting of a bus A70132 and a trailer with a total weight of 16,000 kg becomes inefficient. To increase the speed, it is necessary to either increase the power of the bus engine or activate the trailer.
